DAY 3 CONVECTIVE OUTLOOK 
   NWS STORM PREDICTION CENTER NORMAN OK
   0230 AM CDT SAT JUN 06 2015

   VALID 081200Z - 091200Z

   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF THE OH/TN
   VALLEYS AND CENTRAL APPALACHIANS...

   ...THERE IS A MRGL RISK OF SVR TSTMS FROM THE SOUTH-CENTRAL HIGH
   PLAINS TO THE NORTHEAST/MID-ATLANTIC STATES...

   ...SUMMARY...
   ISOLATED STRONG TO SEVERE THUNDERSTORMS WILL BE POSSIBLE ON MONDAY
   FROM THE SOUTH-CENTRAL HIGH PLAINS TO THE TENNESSEE VALLEY...CENTRAL
   APPALACHIANS...AND NORTHEAST STATES.

   ...OH/TN VALLEYS TO THE NORTHEAST/MID-ATLANTIC STATES...
   AN UPPER TROUGH IS EXPECTED TO AMPLIFY OVER THE UPPER OH RIVER
   VALLEY/NORTHEAST STATES ON MONDAY...WITH A COLD FRONT SPREADING
   EAST-SOUTHEASTWARD ACROSS THE OH/TN VALLEYS AND
   NORTHEAST/MID-ATLANTIC STATES. EARLY-DAY SHOWERS/THUNDERSTORMS AND
   RELATED CLOUD COVER ARE LIKELY TO ACCOMPANY THE ADVANCING
   FRONT...WHICH LEADS TO UNCERTAINTY REGARDING PRE-FRONTAL
   DESTABILIZATION...PARTICULARLY WITH NORTHEASTWARD EXTENT INTO THE
   NORTHEAST STATES. SOUTH OF THE EARLY DAY CLOUD
   COVER/PRECIPITATION...CURRENT THINKING IS THAT STRONG/SEVERE
   THUNDERSTORMS ARE MOSTLY LIKELY TO INTENSIFY MONDAY AFTERNOON JUST
   AHEAD OF THE FRONT ACROSS PORTIONS OF THE LOWER/MIDDLE OH VALLEY AND
   TN VALLEY TO THE CENTRAL APPALACHIANS VICINITY VIA A
   WEST-SOUTHWESTERLY FEED OF MOIST/UNSTABLE AIR. 35-55 KT
   WEST-SOUTHWESTERLY MID-LEVEL WINDS WILL CONTRIBUTE TO ORGANIZED
   MULTICELLS AND POTENTIALLY SOME SUPERCELLS WITH DAMAGING
   WINDS/SEVERE HAIL AS THE PRIMARY HAZARDS. ADDITIONAL PORTIONS OF THE
   NORTHEAST/MID-ATLANTIC STATES MAY ULTIMATELY WARRANT INCLUSION INTO
   A CATEGORICAL SLIGHT RISK PENDING FURTHER DETAILS/CONFIDENCE IN MORE
   CONSEQUENTIAL PRE-FRONTAL DESTABILIZATION.

   ...SOUTH-CENTRAL PLAINS TO OZARKS...
   ISOLATED STRONGER THUNDERSTORMS MAY DEVELOP MONDAY AFTERNOON/EARLY
   EVENING ACROSS SOUTHEAST CO/NORTHEAST NM VIA LOW-LEVEL UPSLOPE
   FLOW...WITH THE POSSIBILITY OF INTENSIFICATION/INCREASED
   ORGANIZATION AS THE STORMS SPREAD EAST-SOUTHEASTWARD WITHIN THE
   INSTABILITY AXIS ACROSS THE SOUTH-CENTRAL HIGH PLAINS. SEVERE
   HAIL/WIND WILL BE POSSIBLE.

   FARTHER EAST...AT LEAST ISOLATED STRONG/SEVERE MULTICELL STORMS ARE
   EXPECTED TO DEVELOP MONDAY AFTERNOON/EARLY EVENING NEAR THE WSW-ENE
   ORIENTED FRONT ACROSS THE SOUTH-CENTRAL PLAINS TO OZARKS. A
   RELATIVELY WARM/MOIST BOUNDARY LAYER IN CONJUNCTION WITH MODERATE
   HIGHER-LEVEL WESTERLIES MAY LEAD TO BOUTS OF LOCALLY DAMAGING
   WINDS/SOME HAIL.

If the NAM 4k is anywhere right we could have a good light show late afternoon/evening for BNA with the k-index at 43 and the potential of some flash flooding being we haven't seen rain in days with the PW's @ 1.92" with the LI @-9 and MUCapes above 3800.Not the greatest wind shear Monday but you can't rule out a mesocyclone.

   1242 AM CDT SUN JUN 07 2015

   VALID 081200Z - 091200Z

   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF THE TN/OH
   VALLEY TO PARTS OF NORTHEAST STATES/DELMARVA...

   ...THERE IS A MRGL RISK OF SVR TSTMS FROM THE SOUTH-CENTRAL HIGH

   ...SUMMARY...
   SEVERE THUNDERSTORMS WILL BE POSSIBLE MONDAY MAINLY ACROSS THE
   TENNESSEE VALLEY...CENTRAL APPALACHIANS...INTO THE NORTHEAST
   STATES...WHILE OTHER STRONG STORMS WILL BE POSSIBLE ACROSS THE
   SOUTH-CENTRAL HIGH PLAINS.

   ...OH/TN VALLEYS TO THE NORTHEAST STATES/DELMARVA...
   AN UPPER TROUGH IS EXPECTED TO AMPLIFY OVER THE UPPER OH RIVER
   VALLEY/NORTHEAST STATES ON MONDAY...WITH A COLD FRONT SPREADING
   EAST-SOUTHEASTWARD ACROSS THE OH/TN VALLEYS AND
   NORTHEAST/MID-ATLANTIC STATES. SCATTERED EARLY-DAY
   SHOWERS/THUNDERSTORMS AND RELATED CLOUD COVER ARE LIKELY TO
   ACCOMPANY THE ADVANCING FRONT...WHICH LEADS TO UNCERTAINTY REGARDING
   PRE-FRONTAL DESTABILIZATION PARTICULARLY WITH EAST-NORTHEASTWARD
   EXTENT INTO THE NORTHEAST STATES/DELMARVA WHERE VERTICAL SHEAR WILL
   BE STRONGER. SOUTH OF THE EARLY DAY CLOUD COVER/PRECIPITATION AND
   POSSIBLE OUTFLOW...CURRENT THINKING IS THAT STRONG/SEVERE
   THUNDERSTORMS ARE MOSTLY LIKELY TO INTENSIFY MONDAY AFTERNOON WITHIN
   A WEAKLY CAPPED/MODERATELY UNSTABLE ENVIRONMENT AHEAD OF THE FRONT
   ACROSS PORTIONS OF THE LOWER/MIDDLE OH VALLEY AND TN VALLEY TO THE
   CENTRAL APPALACHIANS VICINITY...BUT POTENTIALLY ALSO ACROSS PARTS OF
   PA/DELMARVA VICINITY WITH THE POSSIBLE AID OF WEAK PRE-FRONTAL
   TROUGHING/TERRAIN. THE WEST-SOUTHWESTERLY FEED OF MOIST/UNSTABLE AIR
   AND STRENGTHENING BELT OF WEST-SOUTHWESTERLY MID-LEVEL WINDS /30-60
   KT BETWEEN 700-500 MB/ WILL CONTRIBUTE TO ORGANIZED MULTICELLS/LINE
   SEGMENTS AND POTENTIALLY A FEW SUPERCELLS WITH DAMAGING WINDS/SEVERE
   HAIL AS THE PRIMARY HAZARDS.

   ...UPPER MIDWEST/UPPER GREAT LAKES...
   WHILE MASS CONVERGENCE WILL WE WEAK...AND MOISTURE WILL BE LIMITED
   /50S F SURFACE DEWPOINTS/ IN THE WAKE OF A PRIOR FRONTAL PASSAGE
   ACROSS MOST OF THE REGION...SUFFICIENT MOISTURE/CONVERGENCE IN
   CONJUNCTION WITH STEEPENING LAPSE RATES AND A WEAK SURFACE TROUGH
   SHOULD ALLOW FOR ISOLATED THUNDERSTORM DEVELOPMENT BY MONDAY
   AFTERNOON. IN THE PRESENCE OF A STRENGTHENING BELT OF NORTHWESTERLY
   MID-LEVEL WINDS...SOME STRONGER STORMS CAPABLE OF GUSTY WINDS AND
   HAIL...POTENTIALLY TO NEAR MARGINALLY SEVERE LEVELS...COULD OCCUR ON
   AN ISOLATED BASIS MONDAY AFTERNOON/EARLY EVENING.

   ...SOUTH-CENTRAL HIGH PLAINS TO OZARKS...
   ISOLATED SEVERE THUNDERSTORMS ARE EXPECTED TO DEVELOP MONDAY
   AFTERNOON/EARLY EVENING ACROSS SOUTHEAST CO/NORTHEAST NM VIA WEAK
   LOW-LEVEL UPSLOPE FLOW...WITH THE POSSIBILITY OF
   INTENSIFICATION/INCREASED ORGANIZATION AS THE STORMS DRIFT/SPREAD
   EAST-SOUTHEASTWARD TOWARD TX PANHANDLE/FAR WESTERN OK WITHIN A
   RELATIVELY SPATIALLY NARROW CORRIDOR OF MODERATE
   INSTABILITY/VERTICAL SHEAR. A TORNADO COULD OCCUR ACROSS NORTHEAST
   NM/FAR SOUTHEAST CO VICINITIES...BUT ISOLATED INSTANCES OF SEVERE
   HAIL AND POSSIBLY STRONGER WIND GUSTS WILL BE THE PRIMARY RISKS.

   FARTHER EAST...A FEW STRONG/POTENTIALLY SEVERE MULTICELL STORMS ARE
   EXPECTED TO DEVELOP MONDAY AFTERNOON/EARLY EVENING NEAR THE WSW-ENE
   ORIENTED FRONT ACROSS OK TO THE OZARKS. A RELATIVELY WARM/MOIST

DAY 1 CONVECTIVE OUTLOOK 
   NWS STORM PREDICTION CENTER NORMAN OK
   0100 AM CDT MON JUN 08 2015

   VALID 081200Z - 091200Z

   ...THERE IS A SLGT RISK OF SVR TSTMS FROM THE MID SOUTH THROUGH THE
   TN/OH VALLEYS TO CENTRAL MD/PA AND PARTS OF SERN NY/NWRN NJ...

   ...THERE IS A MRGL RISK OF SVR TSTMS SURROUNDING THE SLIGHT RISK
   AREA FROM THE NORTHEAST STATES TO THE TN VALLEY...WESTWARD TO THE
   SRN HIGH PLAINS AND INTO THE MIDWEST/UPPER GREAT LAKES...

   ...SUMMARY...
   SEVERE THUNDERSTORMS WILL BE POSSIBLE TODAY INTO THIS
   EVENING...MAINLY ACROSS PARTS OF THE TENNESSEE AND OHIO VALLEYS TO
   CENTRAL MARYLAND...PENNSYLVANIA...AND PARTS OF SOUTHEAST NEW YORK
   AND NORTHWEST NEW JERSEY.  OTHER STRONG STORMS WILL BE POSSIBLE FROM
   ARKANSAS WESTWARD TO THE SOUTHERN HIGH PLAINS AND ACROSS THE MIDWEST
   AND UPPER GREAT LAKES.

   ...SYNOPSIS...
   A BROAD MID- TO UPPER-LEVEL TROUGH WILL UNDERGO FURTHER
   AMPLIFICATION THIS FORECAST PERIOD...MOVING E/SE OF THE UPPER AND
   MID MS VALLEY REGION...ACROSS THE GREAT LAKES AND OH/TN VALLEYS
   TOWARD THE MID-ATLANTIC AND NORTHEAST STATES.  A COUPLE OF IMPULSES
   WILL MOVE ACROSS THE OH VALLEY TO THE NORTHEAST STATES WITHIN A BAND
   OF 50+ KT SWLY MIDLEVEL WINDS.  MEANWHILE...A MORE PROMINENT
   SHORTWAVE TROUGH IS EXPECTED TO DIG SEWD THROUGH THE BACKSIDE OF THE
   PARENT TROUGH...ACROSS THE UPPER MS VALLEY TO THE LOWER OH VALLEY BY
   09/00Z.  THIS VIGOROUS SHORTWAVE TROUGH WILL THEN TURN EWD MONDAY
   EVENING TRACKING TOWARD THE MID-ATLANTIC AND NORTHEAST STATES.

   ...MID-SOUTH TO THE NORTHEAST STATES...
   AT THE SURFACE...A COLD FRONT SHOULD EXTEND FROM LOWER MI SWWD
   THROUGH CENTRAL MO TO SRN KS AT 12Z.  THIS BOUNDARY WILL REMAIN
   PROGRESSIVE TODAY AND SHOULD REACH THE LOWER GREAT LAKES...AND TRAIL
   SWWD THROUGH OH TO THE MID-SOUTH BY 12Z TUESDAY.  A VERY MOIST
   ENVIRONMENT WILL EXTEND ACROSS THE WARM SECTOR FROM THE OZARKS
   THROUGH OH/TN VALLEYS TO THE NORTHEAST STATES WITH PRECIPITABLE
   WATER VALUES EXCEEDING 1.5 INCHES.

   AREAS OF CONVECTION AND RELATED DEBRIS CLOUDS WILL BE RATHER
   PERVASIVE OVER PORTIONS OF THE WARM SECTOR THIS MORNING ACROSS MUCH
   OF THE SLIGHT RISK AREA.  DESPITE POOR MIDLEVEL LAPSE
   RATES...POCKETS OF DIABATIC HEATING ARE EXPECTED TO OCCUR BY
   MID-DAY...YIELDING MODERATE-STRONG INSTABILITY AMIDST GENERALLY
   MIDDLE/UPPER 60S SURFACE DEW POINTS.  WEAK MLCINH AND FORCING FOR
   ASCENT ATTENDANT TO THE AFOREMENTIONED LEAD MIDLEVEL IMPULSES
   SUGGEST AN INCREASE IN TSTM COVERAGE/INTENSITY BY AFTERNOON IN
   VICINITY OF DIFFERENTIAL HEATING BOUNDARIES AND REMNANT MORNING
   OUTFLOW BOUNDARIES.  MODERATE H85-H5 SWLYS/WSWLY ARE FORECAST TO
   ENCOURAGE CONVECTIVE BANDING WITH OCCASIONAL FAST-MOVING/SMALL
   EMBEDDED BOWING SEGMENTS CAPABLE OF DAMAGING WIND GUSTS. THIS
   ACTIVITY WILL SPREAD GENERALLY EWD WITH TIME.  A FURTHER INCREASE IN
   TSTM COVERAGE/INTENSITY MAY OCCUR ACROSS THE LOWER OH VALLEY REGION
   AS THE STRONGER FORCING FOR ASCENT AND SUBSEQUENT STRENGTHENING OF
   WIND FIELDS OCCUR WITH THE APPROACH OF THE DIGGING UPPER MS VALLEY
   SHORTWAVE TROUGH.  HIGHER SEVERE PROBABILITIES MAY BE NEEDED IN
   LATER OUTLOOKS...IF CONFIDENCE IN THIS SCENARIO INCREASES.

   A TORNADO OR TWO WILL ALSO BE POSSIBLE...ESPECIALLY WITH ANY
   ESTABLISHED LEWP PATTERNS.  THE GREATEST TORNADO THREATS SHOULD BE
   OVER THE OH/TN VALLEYS WITH A SEPARATE AREA EXTENDING FROM CENTRAL
   MD TO SERN NY/NWRN NJ WHERE LOW-LEVEL CONVERGENCE ALONG A
   STRENGTHENING SLY LLJ THIS AFTERNOON/EVENING SHOULD ENHANCE
   LOW-LEVEL SHEAR.  THIS LATTER THREAT AREA MAY EXTEND FARTHER NORTH
   INTO MORE OF SERN NY...BUT CURRENTLY FORECAST WEAKER INSTABILITY
   PRECLUDES THIS INCLUSION AT THIS TIME.

   ...UPPER GREAT LAKES REGION AND MIDWEST...
   MASS CONVERGENCE WILL BE RELATIVELY WEAK.  LIMITED MOISTURE /50S F
   SURFACE DEW POINTS/ IN THE WAKE OF A PRIOR FRONTAL PASSAGE ACROSS
   MOST OF THE REGION AND DIABATIC HEATING SHOULD RESULT IN MLCAPE OF
   AT LEAST 1000 J/KG.  SUFFICIENT CONVERGENCE IN CONJUNCTION WITH
   STEEPENING LAPSE RATES AND A WEAK SURFACE TROUGH SHOULD ALLOW FOR
   TSTM DEVELOPMENT BY AFTERNOON.  IN THE PRESENCE OF A STRENGTHENING
   BELT OF NWLY MID-LEVEL WINDS...SOME STRONGER STORMS CAPABLE OF GUSTY
   WINDS AND HAIL...POTENTIALLY TO NEAR MARGINALLY SEVERE
   LEVELS...COULD OCCUR ON AN ISOLATED BASIS THIS AFTERNOON/EARLY
   EVENING.

   ...SOUTH-CENTRAL HIGH PLAINS TO OZARKS...
   ISOLATED SEVERE TSTMS ARE EXPECTED TO DEVELOP MONDAY AFTERNOON/EARLY
   EVENING ACROSS SOUTHEAST CO/NORTHEAST NM WITHIN WEAK LOW-LEVEL
   UPSLOPE FLOW.  THE POSSIBILITY EXISTS FOR  INTENSIFICATION/INCREASED
   ORGANIZATION AS THE STORMS DRIFT/SPREAD
   E/SEWD TOWARD THE TX PANHANDLE WITHIN A RELATIVELY SPATIALLY NARROW
   CORRIDOR OF MODERATE INSTABILITY/VERTICAL SHEAR.  A TORNADO COULD
   OCCUR...BUT ISOLATED INSTANCES OF SEVERE HAIL AND POSSIBLY STRONGER
   WIND GUSTS WILL BE THE PRIMARY RISKS.

   FARTHER EAST...A FEW STRONG TO POTENTIALLY SEVERE MULTICELL STORMS
   ARE EXPECTED TO DEVELOP THIS AFTERNOON/EARLY EVENING NEAR A WEAK
   SURFACE FRONT ACROSS OK TO THE OZARKS.  A RELATIVELY WARM/MOIST
   BOUNDARY LAYER WITH MODERATE INSTABILITY IN CONJUNCTION WITH
   MODERATE HIGHER-LEVEL WESTERLIES COULD LEAD TO BOUTS OF LOCALLY
   DAMAGING WINDS/SOME HAIL.

SPC shinks tornado 5% at 13Z and rightfully so. Looks like morning line going up Middle Kentucky into Mid/West Tennessee is too early and will crush CAPE for the eastern Valley. Second line should redevelop farther northwest, where the airmass will recover more, but winds will be veered off.

 

I'm not sure I believe the HRRR with its hideous performance recently. It blows up two lines with the stronger one west, but seems like too much going on. RAP holds onto a dominant front (east) line but I think it has already blown the forecast. 12Z hi-res NAM echos the 2nd line (west) dominant forecast, without all the HRRR noise. However winds are veered off back there. Appears wind and hail are the main threats today. No ENH is a good call though; again, low CAPE with the morning line going too early.

 

Otherwise mid level and upper level winds are healthy for this time of year. Maybe we can get some shelfies or pics of other benign but scary looking clouds, lol!

I was very happy with the storms we got last night.  Some of the hardest rain I've ever seen but wind gusts were not too bad and no hail that I noticed.  The lightning was the best I've seen this year.  Hopefully we can get into a pattern of more consistent summer afternoon pop-up storms.

The rain was definitely nice! It wasn't overly heavy at the house, but it was steady for most of the evening and a few heavier bursts. It was the most rain in one system we've had in quite awhile, I guess since April. Ended up with almost 1.25in

KCHA gusted to 56 (1 minute reading was 47 mph) with the first storm at 5:30. I had more wind IMBY from the second round that hit around sunset. There was apparently a lot of damage in the East Ridge area. The newspaper said that 8 homes were deemed uninhabitable due to falling trees.

I was at Brown Acres when the first one hit...it took out 4-5 trees around the golf course....we bolted about 15 mins before the second came in. So I can give no comparison. But there was no hail...just quite a bit of wind.

GFS just threw another bone into the forecast for the Valley.It's still sticking with the trough and this LP S off La would ride it seemingly and as it crosses into Ark and into Ky but the winds would be out of the S TO SW,The last run of the GFS is showing the LLJ AT 45kts in the western Valley with the shear at 0-1 km at 30 kts,Wed afternoon.Only thing the models seem to agree on at this point is there will be some record breaking temp east of us towards the SE states

Ugh, if KMGE manages to stay be,ow 95 today I'll be lucky.... Good lord it's hot down this way. Hopefully further north into the TV it's not as hot.

I'm already six degrees ahead of yesterday during the past two temp updates, if that trend continues I'm looking at 96 for a high, the NWS says 94 today and 95 tomorrow......

Certainly by the GEFS  you guys in your area look toasty coming up,not that our area is relative cool,just not as hot as you guys.

 

The weeklies last Thursday is showing a ridge (592dm) building into the Valley from the W the last week of June then shifting east into the Mid Atl.Today's MJO is showing it going into phase 6 during the same time so it's another period to watch in the long term,maybe something pops up in the GOM during this time frame

Well I got lucky and only hit 91. Today may be a different story. NWS is going with 94. Based on what you're saying it looks to stay hot.

Yes they are downsloping a bit off the Apps. In the larger scale the SER looks to maintain control for the next 10-14 days, perhaps longer. Any breaks will be minimal. Texas system now looks to be shunted northwest, but may still come around this way. if not, well it'll just get more humid.

595dm+ death ridge incoming? The signal on the models is sick heat. I'm not expecting another 108 like we had a couple of summers ago but this is a nasty heat wave developing. This one looks to have some staying power and humidity which IMO is worse than a single extremely hot but very dry day.

   ...SUMMARY...
   SEVERE THUNDERSTORMS WITH A THREAT FOR LARGE HAIL...DAMAGING WIND
   AND POSSIBLY A FEW TORNADOES ARE EXPECTED OVER THE NORTHERN PLAINS
   INTO A PART OF MINNESOTA FRIDAY. ELSEWHERE A COUPLE OF TORNADOES
   CANNOT BE RULED OUT FROM NORTHEAST ARKANSAS...SOUTHEAST
   MISSOURI...WESTERN TENNESSEE INTO SOUTHWESTERN PORTIONS OF THE OHIO
   VALLEY DURING THE DAY.

   ...SYNOPSIS...

   FASTER BELT OF WLYS WILL PERSIST OVER THE NRN THIRD OF THE U.S. WITH
   SEVERAL EMBEDDED IMPULSES MOVING THIS ZONE OF FLOW FROM THE NRN
   ROCKIES INTO THE NRN PLAINS. REMNANTS OF TROPICAL STORM BILL WILL
   MOVE NEWD THROUGH THE LOWER-MID MS VALLEY INTO SWRN PORTIONS OF THE
   OH VALLEY.

   ...NRN PLAINS AREA INTO CNTRL MN...

   ELEVATED STORMS SHOULD BE ONGOING OVER A PORTION OF ND EARLY FRIDAY
   WITHIN ZONE OF ISENTROPIC ASCENT NORTH OF A CONVECTIVELY-ENHANCED
   WARM FRONT. THIS ACTIVITY WILL SHIFT EWD INTO NRN MN DURING THE DAY
   IN ASSOCIATION WITH A LEAD SHORTWAVE TROUGH EMBEDDED WITHIN ZONE OF
   FASTER WLYS. THE ATMOSPHERE WILL DESTABILIZE IN WAKE OF EARLY STORMS
   FROM ERN MT THROUGH THE DAKOTAS WHERE AN AXIS OF MID 60S DEWPOINTS
   WILL HAVE ADVECTED THROUGH WARM SECTOR BENEATH STEEPENING MID-LEVEL
   LAPSE RATES. THIS WILL SUPPORT MODERATE TO STRONG INSTABILITY WITH
   MLCAPE FROM 2000-3000 J/KG. A CAP RESULTING FROM AN EWD ADVECTING
   EML WILL PROBABLY LIMIT SURFACE BASED STORM DEVELOPMENT MUCH OF THE
   DAY.

   STORMS ARE EXPECTED TO EVENTUALLY DEVELOP OVER THE HIGHER TERRAIN
   FROM SRN MT INTO NRN WY BY LATE AFTERNOON AND SPREAD ESEWD AS NEXT
   UPSTREAM SHORTWAVE TROUGH MOVES THROUGH WRN/CNTRL MT. THIS ACTIVITY
   WILL POSE A THREAT FOR LARGE HAIL AND DAMAGING WIND. OTHER STORMS
   MAY DEVELOP ON A SEWD ADVANCING COLD FRONT ACCOMPANYING THE
   SHORTWAVE TROUGH FROM ERN MT INTO WRN ND. THUNDERSTORM COVERAGE
   SHOULD INCREASE DURING THE EVENING OVER THE DAKOTAS AS ACTIVITY
   MOVING SEWD OFF THE HIGHER TERRAIN AND ALONG THE COLD FRONT GROWS
   UPSCALE SUPPORTED BY AN INTENSIFYING LLJ. PRIOR TO UPSCALE GROWTH
   STRONG VERTICAL SHEAR WILL PROMOTE SUPERCELLS WITH LARGE HAIL AND
   POSSIBLY A FEW TORNADOES WITH INITIAL STORMS. HOWEVER...DAMAGING
   WIND SHOULD EVENTUALLY BECOME THE DOMINANT THREAT. HAVE INCLUDED AN
   ENHANCED THREAT AREA DUE TO POTENTIAL FOR A MORE CONCENTRATED SWATH
   OF DAMAGING WIND DURING THE EVENING/OVERNIGHT AS STORMS ORGANIZE
   INTO LEWP/BOWING SEGMENTS.

   ...SERN MO THROUGH SWRN PORTIONS OF THE OH VALLEY...

   CORRIDOR OF MODERATE-STRONG LOW-LEVEL SHEAR ASSOCIATED WITH REMNANTS
   OF TROPICAL STORM BILL WILL PERSIST AND SPREAD ENEWD DURING THE DAY
   INTO THE WRN TN VALLEY AND SWRN PORTION OF THE OH VALLEY. SOME
   THREAT FOR A FEW TORNADOES WILL REMAIN...BUT UNCERTAINTY REGARDING
   DEGREE OF BOUNDARY LAYER DESTABILIZATION PRECLUDES MORE THAN 5%
   SEVERE PROBABILITIES AT THIS TIME.

   ...THERE IS A MRGL RISK OF SVR TSTMS FROM MIDDLE TN INTO KY...

   ...THERE IS A MRGL RISK OF SVR TSTMS OVER A PORTION OF THE CNTRL
   HIGH PLAINS...

   ...SUMMARY...
   STRONG TO SEVERE STORMS ARE EXPECTED TO DEVELOP FROM PARTS OF IOWA
   INTO SOUTHEAST MINNESOTA...WISCONSIN AND NORTHERN MISSOURI. A MORE
   MARGINAL RISK FOR SEVERE STORMS WILL EXIST OVER A PORTION OF LOWER
   MICHIGAN...TENNESSEE AND KENTUCKY AND THE CENTRAL HIGH PLAINS.

   ...MID MS VALLEY INTO THE GREAT LAKES AREA...

   RICHER MOISTURE WITH MID-UPPER 60S NEAR SFC DEWPOINTS WILL ADVECT
   NEWD THROUGH PRE-FRONTAL WARM SECTOR SATURDAY WHERE MID-LEVEL LAPSE
   RATES WILL STEEPEN AS THE EML ADVECTS EWD...SUPPORTING 2000-3000
   J/KG MLCAPE. THIS REGION WILL REMAIN WITHIN BELT OF FASTER WLYS
   WHERE A LOW-AMPLITUDE SHORTWAVE TROUGH WILL MOVE FROM MN EARLY IN
   THE PERIOD INTO THE GREAT LAKES AREA DURING THE AFTERNOON. STORMS
   WILL LIKELY BE ONGOING OVER A PORTION OF MN DURING THE MORNING AND
   WILL DEVELOP ESEWD DURING THE DAY IN ASSOCIATION WITH THE LEAD
   SHORTWAVE TROUGH AND ATTENDANT SWLY LLJ. THOUGH CAPPING COULD BE AN
   ISSUE IN MUCH OF WARM SECTOR...SOME SWD DEVELOPMENT ALONG THE FRONT
   AND OUTFLOW BOUNDARIES IS POSSIBLE IF SUFFICIENT BOUNDARY LAYER
   DESTABILIZATION OCCURS. STRONG VERTICAL SHEAR WILL SUPPORT ORGANIZED
   STORMS INCLUDING BOWING SEGMENTS AND A FEW SUPERCELL STRUCTURES.

   ...CNTRL TN THROUGH KY...

   A RISK FOR A FEW TORNADOES WILL PERSIST IN ASSOCIATION WITH REMNANTS
   OF TS BILL. HOWEVER...DEGREE OF ANY SUCH THREAT WILL DEPEND ON HOW
   MUCH BOUNDARY LAYER DESTABILIZATION OCCURS WHICH REMAINS UNCERTAIN
   SO WILL MAINTAIN LOW PROBABILITIES AT THIS TIME.

   ...CNTRL HIGH PLAINS...

   ELEVATED STORMS DEVELOPING OVERNIGHT IN WEAK WARM ADVECTION REGIME
   MAY POSE A MARGINAL RISK FOR MAINLY ISOLATED HAIL.

Yesterdays weeklies continue to show the SER breaking down and and the ridge shifts to the NW then what happens after that is cloudy IMHO.The weeklies now show a ridge around the lower plains during the July 2-3 time frame then it starts to extend into the heart of the Valley around the 4th
