ChiWxWatcher Posted April 30, 2012 Share Posted April 30, 2012 LOT hinting at severe weather Thursday night. LONG TERM...THURSDAY NIGHT THROUGH MONDAYTHE ACTIVE PATTERN LOOKS TO CONTINUE LATE THIS WEEK INTO EARLY NEXT WEEK WITH A POTENTIAL FOR SOME COOLER AIR OVER THE WEEKEND INTO EARLY NEXT WEEK...ESPECIALLY FOR THE NORTHERN CWA/NEAR THE LAKE. BROAD MID/UPPER LEVEL RIDGING OVER THE EASTERN CONUS WILL FLATTEN OUT AND IT APPEARS FAIRLY DEEP TROUGHING WILL DIG INTO THE NORTHEAST US OR SOUTHEASTERN CANADA BY THE WEEKEND. AT THE SAME TIME...A TROUGH WILL DIG INTO THE WESTERN CONUS. THESE DEVELOPMENTS WILL SUPPORT RENEWED RIDGING EXTENDING FROM MEXICO UP THROUGH THE CENTRAL CONUS. AT THE SURFACE...A QUASI STATIONARY FRONTAL BOUNDARY IS EXPECTED TO SET UP JUST NORTH OF THE CWA AND THEN GRADUALLY SAG SOUTH OVER THE WEEKEND AS LARGE SURFACE HIGH PRESSURE TRIES TO BUILD DOWN FROM CENTRAL CANADA. THIS WILL BRING SYNOPTIC ONSHORE/NE FLOW BY LATE SATURDAY...ENDING THE STRING OF UNSEASONABLE WARMTH...WITH THIS MOST LIKELY TO OCCUR FOR THE NORTHERN HALF OF THE CWA AND/OR LOCATIONS CLOSER TO THE LAKE. WEAK WAVES OF SURFACE LOW PRESSURE WILL OCCASIONALLY RIDE ALONG THE BOUNDARY INTO EARLY NEXT WEEK...BRINGING ANOTHER EXTENDED FORECAST WITH POPS THROUGHOUT. IT IS A DIFFICULT PATTERN TO HANDLE INDIVIDUAL FEATURES OF NOTE...SO THE MODELS REALLY DO NOT HAVE MUCH AGREEMENT IN TERMS OF PLACEMENT AND TIMING OF FEATURES THAT WILL IMPACT OUR SENSIBLE WEATHER. ALTHOUGH POPS HAVE AGAIN BEEN INCLUDED FOR EVERY PERIOD...THERE WILL CERTAINLY BE DRY TIMES...WITH REFINEMENT OF DETAILS OCCURRING AS WE GET CLOSER IN THE FORECAST. THE BIG STORY WILL BE THE SUMMER HEAT AND HUMIDITY SOUTH OF THAT BOUNDARY...WITH 850 MB TEMPERATURES IN THE MID TEENS SUPPORTING HIGH TEMPERATURES IN THE 70S AND 80S FRIDAY AND SATURDAY...ALONG WITH DEWPOINTS WELL INTO THE 60S. THE CONCERN IS THERE FOR ORGANIZED CONVECTION POTENTIALLY PRODUCING HEAVY RAIN ON THE NOSE OF 30-40 KT LOW LEVEL JET ON THURSDAY EVENING/NIGHT. PWATS AND 850 MB MOISTURE FLUX CONTINUE TO BE ADVERTISED WELL ABOVE CLIMO AT 2 SD OR HIGHER...AND SOUNDINGS SHOW PLENTY OF INSTABILITY TO BE TAPPED INTO. CANNOT RULE OUT SEVERE THUNDERSTORMS LATE THURSDAY...WITH POSSIBILITY OF DECENT LOW LEVEL SHEAR AND CAPE AT OR IN EXCESS OF 2000 J/KG. HOWEVER...WITH CORE OF JET STREAM WELL TO NORTH...MIDLEVEL FLOW WILL ONLY BE ON THE ORDER OF 35 KT OR SO...SO DEEP LAYER SHEAR PROFILES WILL BE MARGINAL. BIGGEST THREAT MAY BECOME THAT OF HEAVY AND POSSIBLY FLOODING RAINS. HIGH CAPE CAN BE EXPECTED FRIDAY AS WELL...AND THEN SOUTH OF WHEREVER THE BOUNDARY SETS UP SATURDAY AND SUNDAY...SO AT LEAST ISOLATED STRONGER STORMS CAPABLE OF PRODUCING VERY HEAVY RAIN CANNOT BE RULED OUT THOSE DAYS EITHER.

Geos Posted April 30, 2012 Share Posted April 30, 2012 MKX severe weather disco: TUESDAY NIGHT...FORECAST CONFIDENCE MEDIUM TO HIGH. EXPECT ONGOING CONVECTION FROM TUESDAY AFTERNOON IN MN/NW WI ON NOSE OF LLJ AND PORTION OF SURFACE WARM FRONT NEAREST SURFACE LOW TO DEVELOP BACK THROUGH IA ALONG TRAILING SURFACE TROUGH/COOL FRONT. STORMS IN WISCONSIN TO MOVE EAST ALONG WARM FRONT...AND FARTHER SOUTH WITH 1000-850 MB THETA-E ADVECTION/CONVERGENCE AS SOUTHERLY 850 MB WINDS VEER SOUTHWEST BEHIND PASSING SHORT WAVE. FORECAST CAPE VALUES HIGHER OVER WESTERN CWA...THOUGH MAGNITUDE IS SUSPECT AS MODEL 2M DEW POINTS AND SFC DEW POINTS ON FORECAST SOUNDINGS LOOK TOO MOIST. WILL TREND CLOSER TO LOWER MOS GUIDANCE. STILL ENOUGH INSTABILITY...STEEP MID-LEVEL LAPSE RATES AND SHEAR FOR MAINLY ELEVATED STRONG STORMS WITH THE POTENTIAL OF LARGE HAIL...ESPECIALLY WEST. FOLLOWED NEIGHBORING OFFICES AND WENT WITH 3-HOURLY POPS. LIKELY POPS AFTER MIDNIGHT IN THE FAR NORTH LINE UP WELL WITH STRONGER LAYER Q-VECTOR CONVERGENCE...MAINLY ALONG SURFACE AND 850 MB FRONTS...THAT WEAKENS AS IT MOVES SOUTHEAST OVER THE REMAINDER OF THE CWA OVERNIGHT...LEADING TO CHANCE POPS ELSEWHERE. WEDNESDAY AND WEDNESDAY NIGHT...FORECAST CONFIDENCE MEDIUM WHERE THE EFFECTIVE SURFACE WARM FRONT SETS UP DUE TO OUTFLOW AND CLOUD DEBRIS FROM TUESDAY NIGHT INTO WEDNESDAY MORNING CONVECTION WILL BE CRITICAL TO AMOUNT OF WARMING AND INSTABILITY AND SUBSEQUENT DEVELOPMENT OF CONVECTION...AND DICTATE MOST-LIKELY LOCATION OF SEVERE WITH NEXT WARM AIR/MOISTURE ADVECTION SURGE LATE WEDNESDAY AFTERNOON AND EVENING. SPC DAY 3 OUTLOOK COVERS MOST OF THE STATE TO ACCOUNT FOR BOTH MORNING SEVERE POTENTIAL IN THE CENTRAL AND NORTH...AND THE AFTERNOON/EVENING POTENTIAL SOUTH AND CENTRAL. BEST CHANCES FOR SEVERE IN THE SOUTH IN THE LATE AFTERNOON/EVENING...WITH THE HIGHER VALUES ON LOCAL CWASP SEVERE CHECK LIST ALIGNING WELL WITH CONVERGENCE ON LEADING EDGE OF 40 KT LOW-LEVEL JET AND ALONG SURFACE WARM FRONT THAT PASSES SOUTH TO NORTH THROUGH FORECAST AREA BETWEEN 00Z AND 06Z THURSDAY. VEERING WIND PROFILE SUGGEST SUPER CELL STORMS LIKELY WITH SUFFICIENT 0-6KM BULK SHEAR OF 35 TO 40 KNOTS. LARGE HAIL AND STRONG WINDS...WITH THE POTENTIAL FOR TORNADOES WITH LOW LEVEL VEERING ALONG THE SURFACE WARM FRONT PRODUCING 0-1KM SHEAR OF 25 TO 35 KNOTS AND 0-1 KM EHI BETWEEN 1.5 AND 2.25. Sounds like several chance at severe weather in different areas. Should keep local forecast offices quite busy! Link to comment Share on other sites More sharing options...
frostfern Posted May 1, 2012 Share Posted May 1, 2012 I'm not sure I agree. The lapse rate between the lake water and the air just above (like feet above) is often very steep. Over the lake, the slice of the atmosphere affected by the lake is usually thin. Not saying development over the lake is never retarded but I think you are overblowing it. I think you guys are taking what I'm saying the wrong way. The lake is less likely to effect convection that's being fed by unstable air being advected in from elsewhere and converging over the lake. However, for the air to be converging over the lake in the first place there has to be some kind of meso or synoptic scale forcing going on. Or, as in the Chicago case there was already a boundary that formed over the land and was advected over the lake by offshore flow. The same thing can happen on the east side of the lake, but it's more unusual to have an offshore flow since the prevailing flow usually has some westerly component. Anyways, if you ever look at visible satellite view of the cu field during peak heating you'll get what I'm saying. If there is a SW flow the cu field pretty much vanishes by the time the air reaches the middle of the lake and doesn't redevelop until the air gets about 20 miles inland on the leeward side. It's pretty hard for convection to initiate in that cu field hole. It usually has to initiate in Wisconsin and then move across the lake. Also, even if the actual marine layer is too thin to reduce the stability of the layer above directly, it does create a boundary layer meso-high circulation due to differential heating. It may be that the differential heating of lake-vs-land does more to inhibit convection than the absolute reduction in CAPE. You could have 2200 ML CAPE over the lake and 2500 ML CAPE over the land. The 2200 ML CAPE over the lake is still plenty of juice for strong convection, yet the convection might still have trouble initiating over the lake because the heating differential is just enough to increase the CINH so that parcels have more trouble reaching the level of free convection.

Stebo Posted May 1, 2012 Author Share Posted May 1, 2012 Not sure about this discussion about convection forming over the lake, I don't expect that to be the case this week so it is an irrelevant topic to this week's potentials. The current expectation with the stuff this week will be that it moves in from the West or forms over Michigan. Link to comment Share on other sites More sharing options...
Hoosier Posted May 1, 2012 Share Posted May 1, 2012 I see some big hail potential upcoming. Models have ample CAPE and really steep mid level 700-500 mb lapse rates (like 8-8.5 C/km especially per GFS) Link to comment Share on other sites More sharing options...

BELT OF BROAD CYCLONIC FLOW WILL PERSIST OVER THE NRN THIRD OF THE COUNTRY. SEVERAL IMPULSES WILL MOVE THROUGH THIS REGIME AND TEND TO MODULATE THE SEVERE POTENTIAL FROM THE CNTRL PLAINS INTO THE UPPER MS VALLEY AND GREAT LAKES. FRONT WILL LIKELY STALL FROM NEB NEWD THROUGH MN AND WI. DRYLINE WILL PERSIST OVER THE SRN PLAINS NWD INTO SWRN NEB WHERE IT WILL INTERSECT THE FRONT. A WARM FRONT WILL CONTINUE LIFTING NEWD THROUGH THE GREAT LAKES. ...CNTRL PLAINS THROUGH UPPER MS VALLEY AND GREAT LAKES... IT STILL APPEARS LEAD IMPULSE WILL EJECT INTO SWRN QUEBEC EARLY WEDNESDAY WITH SWLY FLOW ALOFT BECOMING NEAR PARALLEL TO FRONT THAT WILL EXTEND FROM WI AND MN SWWD INTO THE CNTRL PLAINS. A MOIST WARM SECTOR WITH LOW TO MID 60S DEWPOINTS WILL RESIDE SOUTH OF FRONT. A FEW STORMS WILL PROBABLY BE ONGOING EARLY IN PERIOD AND MIGHT CONTRIBUTE TO EFFECTIVE BOUNDARY RESIDING SOUTH OF THE SYNOPTIC FRONT. INITIAL CONVECTION WILL SHIFT EWD AND WEAKEN ALLOWING BOUNDARY LAYER DESTABILIZATION IN ITS WAKE. STEEP LAPSE RATES WILL ADVECT ABOVE THE MOIST AXIS RESULTING IN MODERATE TO STRONG INSTABILITY AS THE BOUNDARY LAYER WARMS. LOW AMPLITUDE SHORTWAVE RIDGING WILL MOVE THROUGH THE AREA BEFORE THE NEXT UPSTREAM TROUGH APPROACHES BY EVENING. ADDITIONAL STORMS WILL LIKELY DEVELOP ALONG THE FRONT AND RESIDUAL OUTFLOW BOUNDARIES FROM NEB INTO THE UPPER MS VALLEY BY LATE AFTERNOON. NRN EXTENT OF WARM SECTOR WILL REMAIN WITHIN BELT OF STRONGER WLYS...AND DEEP LAYER WINDS WILL STRENGTHEN AS THE NEXT UPSTREAM SHORTWAVE TROUGH APPROACHES THE NRN PLAINS. VERTICAL SHEAR FROM 35-40 KT WILL PROMOTE ORGANIZED SEVERE STORMS INCLUDING SUPERCELLS...BUT SOME OF THE STORMS MAY EVENTUALLY GROW UPSCALE INTO ONE OR MORE MCS CLUSTERS SUPPORTED BY STRENGTHENING LLJ. LARGE HAIL...DAMAGING WIND AS WELL AS A FEW TORNADOES WILL BE POSSIBLE. Link to comment Share on other sites More sharing options...
RCNYILWX Posted May 1, 2012 Share Posted May 1, 2012 Beat me to it. Placement of the slight risk and higher 30% and hatched area seems very reasonable. Northern IL portion of slight will likely be too capped and very marginal shear, but with steep midlevel lapse rates and high CAPE, still seems warranted to keep part of the LOT CWA in the 15% probs. From NAM and GFS soundings, Thursday looks like it will have even more instability and steeper mid level lapse rates than Weds, but similar capping and marginal shear issues. As Hoosier alluded to earlier though, if any updrafts can be sustained on Weds and Thurs, large hail would be a good bet. This period also looks like a pretty good set-up for nocturnal MCS's for somewhere in the region with plenty of elevated instability remaining overnight and the low level jet ramping up.

wisconsinwx Posted May 1, 2012 Share Posted May 1, 2012 most of the previous high res runs had something That's true, I wasn't sure whether to trust the GFS repeated dry runs or the hi-res models a bit beyond their useful range. Oh well, if not overnight tonight, we should still have chances late Wednesday and Thursday for an MCS. Link to comment Share on other sites More sharing options...

The current expectation with the stuff this week will be that it moves in from the West or forms over Michigan. The cursed t-storm killing lake is relevant to me considering my location. It's a rare case when it's a positive factor (i.e. backed SSE flow setting up a lake breeze) rather than a negative. I guess I'll be happy to get a nocturnal MCS or weakening squall line rolling in from Wisconsin. Discrete afternoon popups are much more interesting to watch but they usually require getting in the car and driving east 20-30 miles or so.

Hoosier Posted May 1, 2012 Share Posted May 1, 2012 5% tor probs in the OV on the new outlook. Nice turning with height especially in the lowest 2 km. May be more of a low instability/high shear threat depending on future warming. Link to comment Share on other sites More sharing options...
