andyhb Posted May 21, 2013 Share Posted May 21, 2013 Another moderate risk in effect for Tuesday... SPC WRF is showing some strong updraft helicity signatures in the Arklatex tomorrow afternoon/evening. DAY 1 CONVECTIVE OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 1259 AM CDT TUE MAY 21 2013 VALID 211200Z - 221200Z ..THERE IS A MDT RISK OF SVR TSTMS ACROSS PARTS OF SW AR SE OK...NW LA...CNTRL TX AND NE TX... ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE SRN PLAINS...OZARKS...MID MS VALLEY...OH VALLEY AND GREAT LAKES... ..SRN PLAINS/ARKLATEX/MID-MS VALLEY AN UPPER-LEVEL TROUGH WILL MOVE EWD FROM THE SRN ROCKIES INTO THE SRN PLAINS TODAY. AT THE SFC...A COLD FRONT WILL ADVANCE SEWD ACROSS CNTRL OK AND WCNTRL TX. AHEAD OF THE FRONT...SFC DEWPOINTS ACROSS THE WARM SECTOR SHOULD BE IN THE MID TO UPPER 60S F RESULTING IN MODERATE TO STRONG INSTABILITY BY THIS AFTERNOON. THUNDERSTORMS ARE FORECAST TO BE ONGOING AT THE START OF THE PERIOD ACROSS ERN OK WHERE AN ISOLATED THREAT FOR HAIL AND WIND DAMAGE MAY EXIST THIS MORNING. WITH SFC HEATING...NEW THUNDERSTORMS ARE FORECAST TO INITIATE ALONG AND AHEAD OF THE COLD FRONT FROM WRN AR SWWD INTO NORTH TX AROUND MIDDAY. THE MODELS QUICKLY EXPAND THUNDERSTORM COVERAGE WITH AN MCS ORGANIZING AND MOVING SEWD ACROSS THE MODERATE RISK AREA. STRONG INSTABILITY...STEEP MID-LEVEL LAPSE RATES AND MODERATE TO STRONG DEEP LAYER SHEAR SHOULD BE SUPPORTIVE OF WIDESPREAD SEVERE THUNDERSTORM DEVELOPMENT ACROSS THE MODERATE RISK AREA WHERE A SIGNIFICANT SEVERE WEATHER EVENT WILL BE POSSIBLE. FORECAST SOUNDINGS AT 00Z/WED FROM LITTLE ROCK SWWD TO AROUND THE DALLAS FORT WORTH METROPLEX SHOW MLCAPE VALUES OF 2500 TO 4000 J/KG WITH 0-6KM SHEAR OF 45 TO 55 KT. THIS ALONG WITH 850 TO 500 MB LAPSE RATES AROUND 7.5 C/KM SHOULD RESULT IN A POTENTIAL FOR SUPERCELLS WITH LARGE HAIL. HAILSTONES OF GREATER THAN 2 INCHES IN DIAMETER WILL BE POSSIBLE WITH THE MORE INTENSE SUPERCELLS. IN ADDITION...THE MORE DOMINANT SUPERCELLS SHOULD BE CAPABLE OF PRODUCING TORNADOES AS THE LOW-LEVEL JET STRENGTHENS. A FEW STRONG TORNADOES COULD OCCUR NEAR THE LOW-LEVEL JET AS BOUNDARY LAYER SHEAR BECOMES MORE FAVORABLE DURING THE EARLY EVENING. THE MODELS SUGGEST CELLS MAY BE DISCRETE AT THE START OF THE EVENT WITH A TRANSITION TO A SQUALL-LINE. THIS WOULD MAKE THE WIND DAMAGE THREAT INCREASINGLY DOMINANT AS A LINEAR MCS ORGANIZES EARLY THIS EVENING. FOR THIS REASON...AN ENHANCED WIND DAMAGE THREAT WILL BE POSSIBLE ACROSS THE MODERATE RISK AREA. ..GREAT LAKES/OH VALLEY SOUTHWEST FLOW WILL BE IN PLACE TODAY FROM THE MID-MS VALLEY NEWD INTO THE GREAT LAKES REGION. AT THE SFC...A LOW IS FORECAST TO MOVE EWD ACROSS THE UPPER MS VALLEY WITH A CORRIDOR OF LOW-LEVEL MOISTURE EXTENDING NNEWD FROM THE LOWER OH VALLEY INTO LOWER MI. SFC DEWPOINTS ACROSS SRN IL...NW IND AND LOWER MI SHOULD BE IN THE MID 60S F RESULTING IN MODERATE DESTABILIZATION. MODEL FORECASTS INITIATE STORMS BY MID AFTERNOON ALONG THE INSTABILITY AXIS WITH STORMS MOVING NEWD ACROSS THE REGION. FORECAST SOUNDINGS ALONG THE INSTABILITY AXIS WEST OF DETROIT AND NORTH OF INDIANAPOLIS AT 21Z SHOW MLCAPE VALUES IN THE 1000 TO 2000 J/KG RANGE WITH STEEP LOW-LEVEL LAPSE RATES AND UNIDIRECTIONAL WIND PROFILES. THIS ENVIRONMENT SHOULD BE FAVORABLE FOR WIND DAMAGE AS CELLS INCREASE IN COVERAGE THIS AFTERNOON. SEVERAL MODEL FORECASTS SHOW AN ENHANCED SEVERE THREAT ACROSS LOWER MI TO THE SOUTHEAST OF THE SFC LOW AND ON THE NOSE OF THE LOW-LEVEL JET. FOR THIS REASON...AN ENHANCED WIND DAMAGE THREAT WILL BE POSSIBLE WITH BOWING LINE-SEGMENTS IN LOWER MI LATE THIS AFTERNOON. LARGE HAIL AND A FEW TORNADOES MAY ALSO OCCUR WITH THE MORE INTENSE CELLS. ..NRN APPALACHIAN MTNS AN UPPER-LEVEL RIDGE WILL BE IN PLACE TODAY ACROSS THE APPALACHIAN MTNS. IN SPITE OF THE RIDGE...MODERATE INSTABILITY IS FORECAST TO DEVELOP FROM PA NEWD ACROSS CNTRL NY WHERE SFC DEWPOINTS SHOULD BE IN THE LOWER TO MID 60S F. THE MODELS APPEAR TO MOVE A DISTURBANCE OVER THE TOP OF THE RIDGE WHICH WOULD HELP WITH CONVECTIVE INITIATION THIS AFTERNOON. IF STORMS CAN DEVELOP IN SPITE OF THE WEAK LARGE-SCALE ASCENT...THEN STEEP LOW-LEVEL LAPSE RATES COUPLED WITH MODERATE INSTABILITY AND SUFFICIENT DEEP LAYER SHEAR COULD BE SUPPORTIVE OF A MARGINAL WIND DAMAGE THREAT. ..BROYLES/MEAD.. 05/21/2013 Link to comment Share on other sites More sharing options...
Shawn Posted May 21, 2013 Share Posted May 21, 2013 Andy, I do not like the look of just the simulated WRF (4-KM). It is definitely conductive of tornadoes. I'd post some maps, but I can't since they're paid. I'm using Weatherbell's, so maybe Ryan has or will post them on his twitter soon. Lets hope something like today doesn't happen again. I noticed some cape in areas of Texas at or over 4000j/kg. You're much smarter with this severe stuff though, maybe it's not as bad as it looks?

andyhb Posted May 21, 2013 Author Share Posted May 21, 2013 Well, if the SPC WRF is on the right track, then we might have some problems today, I checked some hodographs from the 00z GFS and they were fairly universally looping upon an increase in the LLJ today. There does seem to be a bit of a veer-back-veer profile today, so we'll have to see if that affects storm characteristics and/or mode. The thermodynamic environment is still very potent, it's been awhile since I personally have seen a single synoptic system be able to tap such a potently unstable environment for such an extended period of time. The area from the DFW area earlier on and then east along the I-30 corridor towards Texarkana and perhaps approaching Little Rock later on, will need to be watched. Obviously with yesterday in mind, it only takes one to create a disaster. Link to comment Share on other sites More sharing options...

I noticed the SPC mentioned the models showing the storms starting out as discrete cells before turning into mainly wind threats. If today ends up being worse than yesterday, especially with Dallas involved, I'm officially turning into a prepper and building a city underground. What you mention about the LLJ strengthening is ominous too and I noticed that it wanted to do it around peak hours for ARK/TX? Hopefully it will end up a straight line wind threat, but I won't hold my breath. Link to comment Share on other sites More sharing options...

I'm afraid we've got boundaries laying around, just like we did in OKC yesterday. Link to comment Share on other sites More sharing options...

Srain Posted May 21, 2013 Share Posted May 21, 2013 Morning e-mail from Jeff: Severe/Tornado Outbreak possible this afternoon/evening over TX Potential for long tracked violent tornadoes across N TX this afternoon and evening SPC moderate risk for severe weather including tornadoes in effect for today for N TX Multi-day severe/tornado outbreak continues to unfold this morning across the US plains which has already produced devastating results. Parent upper level storm system responsible for the daily outbreaks continues to spin over the northern plains with a slow moving cold front across OK at the current time. Air mass south of this front and east of the dry line is incredibly moist and unstable with frequent dewpoints in the 70’s and CAPES values of 1500-2500 J/kg. With surface heating, the air mass over N and C TX will become extremely unstable by midday with CAPE values approaching 4000-5000 J/kg ahead of the eastward moving dry line and south of the southward moving frontal boundary. Short wave moving out of New Mexico will help erode the capping overhead by early afternoon and expect explosive supercell development along both the dry line and cold front. Storms will go quickly severe with hail to greater than 2 inches likely. Initial mode will be very dangerous supercells capable of strong rotation and tornadoes given the degree of instability and shear in place. Current thinking is that the greatest tornado threat will be along I-20 including the Dallas/Fort Worth metro areas with a secondary threat along/west of I-35 all the way to west of Austin along the dry line. Best ingredients for potentially devastating tornadoes will be over N TX into AR and NW LA although the moderate risk outline does clip our northern set of counties. Severe weather event will unfold NW of SE TX this afternoon and affect at least the north counties of our area this evening/overnight. Initial supercells will congeal into clusters and lines with the tornado threat weakening after dark and the threat for wind damage increasing as lines bow outward. Capping across our region looks to remain fairly potent, but very strong heating combined with lift from an approaching short wave will likely be enough to break the cap and allow central TX storms to move across the northern 1/3rd of our region or roughly from Columbus to Conroe to Livingston. Storms may attempt to build southward toward I-10 in the overnight hours, but it remains to be seen as to how strong the capping is over the southern portions of the area. Think the main severe threat for SE TX will be wind damage and potentially very large hail. Tornado indices are fairly favorable from College Station to the Huntsville area this afternoon, but this is prior to the cap being breached. By early evening when the capping weakens likely allowing storms to develop, the tornado threat appears to be reduced. Should the cap weaken quicker than expected, the tornado threat across our northern counties will be increased Low level boundary will remain in place on Wednesday and expect a continued threat for strong to severe storms across the central and southern counties with large hail and damaging winds being the main threat. Residents across TX need to review their severe weather and tornado safety plans. SPC Severe Weather Outlook: Link to comment Share on other sites More sharing options...
canderson Posted May 21, 2013 Share Posted May 21, 2013 My entire family, save for my brother in Houston, is living all through Dallas to the Tyler/Longview area. I'm worried today. NWS Shreveport is warning everyone to be prepared for significant severe weather - holding emergency planners calls this morning in front of the line.

DISCUSSION...MOSAIC RADAR IMAGERY THE LAST FEW HOURS INDICATED TSTMS CONTINUED TO DEVELOP AND MOVE ENEWD ACROSS CENTRAL...ERN OK INTO WEST CENTRAL AR...WHILE ADDITIONAL STORMS HAVE DEVELOPED SWWD THROUGH SWRN OK TO WRN N TX. THE ENTIRE EXTENT OF THE TSTM ACTIVITY APPEARS TO BE ELEVATED INCLUDING THE LATTER SWRN OK/WRN N TX STORMS THAT HAVE TENDED TO BECOME UNDERCUT BY A SWD ADVANCING COLD FRONT. INCREASING FORCING FOR ASCENT WITH AN APPROACHING SHORTWAVE TROUGH AND LOW LEVEL WAA OVER N TX AND SRN OK WILL SUPPORT CONTINUED TSTM DEVELOPMENT THROUGH THIS MORNING. VISIBLE SATELLITE IMAGERY SHOWS THE LIKELIHOOD FOR ABUNDANT SURFACE HEATING ALONG AND SOUTH OF THE RED RIVER...WHICH WILL FURTHER BOOST AN ALREADY MODERATELY UNSTABLE ENVIRONMENT...WITH THE POTENTIAL FOR STORMS TO BECOME SURFACE BASED. FURTHER STRENGTHENING OF WSWLY MIDLEVEL WINDS/BULK SHEAR WITH THE APPROACH OF THE SRN HIGH PLAINS TROUGH WILL SUPPORT STORM ORGANIZATION. SWLY SHEAR VECTORS ORIENTED PARALLEL TO THE ONGOING STORMS AND NEW DEVELOPMENT WILL FAVOR LINE SEGMENTS/BOWS WITH DAMAGING WINDS THE PRIMARY THREAT. HOWEVER...THE PRESENCE OF STEEP MIDLEVEL LAPSE RATES /NEAR 9 C PER KM ON THE 12Z FORT WORTH TX SOUNDING/ SUGGESTS HAIL WILL BE A THREAT AS WELL.

Srain Posted May 21, 2013 Share Posted May 21, 2013 Carefully watching the Hill Country area this morning. Developing CU field and a rather potent upper level jet streak dropping SE over New Mexico may well enhance severe storm development a bit further S this afternoon.

No way we are chasing east of Dallas I-35 isn't perfect as a boundary, but from the Red River to San Antonio, it pretty much is the boundary between where there are enough/large enough trees to obstruct viewing and where there aren't.

No way we are chasing east of Dallas lots of open area between Waco and Temple/Killeen you could get some good shots. just don't want to go too far south of Killeen/Temple as you start to get mixed up with the folks in Austin and also Bryan/College Station/Texas A&M. you might want to check with MSP to see if there's any construction to worry about in central TX, given that last I knew he goes to A&M.

This. Stay north of Salado at all costs, really. Be wary of Killeen too a bit w/ Fort Hood traffic. North of there up to Temple to Waco and over 31 toward Corsicana (but avoid Corsicana as traffic is tough to navigate around) is a good shot. I 20 isn't bad for chasing (down that many times) but you're in the forests once to Canton and east so you gotta be careful there. You can pick it up off 35 and jog east quickly if you must.
