Sydney Claridge Posted March 14, 2019 Share Posted March 14, 2019 I had been wondering about the storms over central IL as well. There's plenty of sunshine to get things destabilized there, and its fairly close to the low pressure system too. Link to comment Share on other sites More sharing options...

DISCUSSION...VISIBLE SATELLITE IMAGERY SHOWS MOSTLY CLEAR SKIES ACROSS CENTRAL IL WITH BREAKS IN THE CLOUDS OVER NORTHEAST IL INTO NORTHWEST IN AS OF 1030AM CDT. A MID-LEVEL VORTICITY MAXIMUM LOCATED OVER THE MID MS VALLEY IS EXPECTED TO MOVE NORTHEAST ACROSS CENTRAL IL DURING THE NEXT SEVERAL HOURS.

GIVEN THE VERY STRONG TO EXTREME SHEAR PROFILE COUPLED WITH THE VERY STEEP LAPSE RATE, IT APPEARS TORNADO POTENTIAL IS GREATER THAN PREVIOUSLY ANTICIPATED AND AN UPGRADE IN TORNADO PROBABILITIES WILL BE REFLECTED IN THE UPCOMING 1630Z CONVECTIVE OUTLOOK.

Sydney Claridge Posted March 14, 2019 Share Posted March 14, 2019 Eagerly anticipating the 1630Z SPC convective outlook. Some changes are bound to be made, especially for central and NE IL, plus NW IN, given the storms in that area. Not to mention that clearing along the Ohio River is bound to introduce some issues down the line for Louisville and Cincinnati as well. Link to comment Share on other sites More sharing options...

Oddly, it doesnt destabilize much though. ~500 cape. Obviously enough for today, but I would have thought clearing would push to 750+ Link to comment Share on other sites More sharing options...

Yep, I'd say an upgrade to MDT is warranted along the OH River Valley; probably a slight deeper west into Chicago as well. Hi-res guidance is killing off those cells in western KY, which doesn't make a lot of sense given the clearing, moisture advection, wind fields, etc. Link to comment Share on other sites More sharing options...

janetjanet998 Posted March 14, 2019 Share Posted March 14, 2019 DAY 1 CONVECTIVE OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 1126 AM CDT THU MAR 14 2019 VALID 141630Z - 151200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON FOR NORTHEASTERN IL AND VICINITY...AND THROUGH LATE EVENING FOR PARTS OF THE TN AND OH VALLEYS... ..SUMMARY SEVERE THUNDERSTORMS ARE LIKELY FROM PORTIONS OF THE SOUTHEAST U.S. INTO THE OHIO VALLEY AND SOUTHERN GREAT LAKES. SEVERAL TORNADOES, A FEW OF WHICH COULD BE STRONG, DAMAGING WINDS AND ISOLATED LARGE HAIL WILL BE POSSIBLE THROUGH THIS EVENING. ..TN VALLEY TO THE OH VALLEY THROUGH THIS EVENING A DEEP SURFACE CYCLONE IN SOUTHEASTERN NE WILL MOVE NORTHEASTWARD OVER IA/WI/UPPER MI BY THIS EVENING, AS AN ASSOCIATED MID-UPPER JET STREAK EJECTS NORTHEASTWARD FROM MO TOWARD THE LOWER GREAT LAKES. A SURFACE COLD FRONT WILL PROGRESS EASTWARD FROM THE MID MS VALLEY TO THE OH VALLEY, AND SOUTHEASTWARD INTO THE LOWER MS VALLEY. A NARROW CORRIDOR OF LOW-LEVEL MOISTENING AND SOME SURFACE HEATING IN CLOUD BREAKS IS EXPECTED IMMEDIATELY AHEAD OF THE COLD FRONT THROUGH THIS AFTERNOON, WHICH WILL SUPPORT SOME DESTABILIZATION AS FAR NORTHEAST SOUTHERN LOWER MI. THE STRONGEST LOW-LEVEL FLOW WILL DEVELOP NORTHEASTWARD ACROSS TN TOWARD OH THROUGH THE AFTERNOON. VERTICAL SHEAR WILL BE VERY STRONG WITHIN THE WARM SECTOR, WITH EFFECTIVE BULK SHEAR OF 70-80 KT AND EFFECTIVE SRH OF 400-600 M2/S2. BOUNDARY-LAYER DEWPOINTS IN THE LOW 60S HAVE SPREAD AS FAR NORTH AS THE LOWER OH RIVER AS OF LATE MORNING, AND SOME ADDITIONAL MOISTENING IS EXPECTED TO THE NORTHEAST THROUGH THE AFTERNOON. MIDLEVEL LAPSE RATES ARE NOT PARTICULARLY STEEP AND SURFACE HEATING WILL BE SLOWED BY THE MORNING CONVECTION/CLOUDS, SO MLCAPE WILL LIKELY REMAIN IN THE 500-1000 J/KG RANGE. WIND PROFILES WILL CLEARLY FAVOR SUPERCELLS, AS WILL THE MODE OF INITIATION ALONG AND EAST OF THE FRONT (NOT STRONG LINEAR FORCING FOR ASCENT). THE VERTICAL SHEAR IS ON THE HIGH END FOR THE MODEST BUOYANCY, BUT IT APPEARS THE COMBINATION WILL BE SUFFICIENT FOR THE STRONGEST/MOST SUSTAINED SUPERCELLS TO PRODUCED ISOLATED STRONG TORNADOES AS THE STORMS ARE ROUGHLY PACED BY THE LOW-LEVEL DESTABILIZATION. ADDITIONAL SUPERCELL DEVELOPMENT WILL BE POSSIBLE LATE THIS AFTERNOON INTO THIS EVENING ALONG THE TRAILING BOUNDARY IN THE VICINITY OF NORTHWESTERN AL. THOUGH THE STRONGEST LOW-LEVEL FLOW WILL DEVELOP NORTH OF THIS AREA BY LATE AFTERNOON, WIND PROFILES WILL REMAIN FAVORABLE FOR SUPERCELLS/TORNADOES GIVEN SOME HEATING IN CLOUD BREAKS AND AN INCREASE IN LOW-LEVEL MOISTURE THROUGH THE AFTERNOON. ..CENTRAL/NORTHEASTERN IL TO SOUTHERN LOWER MI THIS AFTERNOON BANDS OF CONVECTION ARE DEVELOPING ALONG THE NOSE OF THE PRIMARY FRONTAL SURGE/DRY SLOT NEAR AND NORTH OF SAINT LOUIS AS OF MID MORNING. THE LOW LEVELS ARE DESTABILIZING NORTHWARD ACROSS IL WITH SURFACE HEATING IN CLOUD BREAKS AND BOUNDARY-LAYER DEWPOINTS OF 56-60 EXPECTED TO REACH NORTHEASTERN IL BY EARLY AFTERNOON. A BROKEN BAND OF LOW-TOPPED THUNDERSTORMS IS EXPECTED ALONG THE WIND SHIFT BY THIS AFTERNOON, WHEN STRONG VERTICAL SHEAR WILL SUPPORT SUPERCELLS CAPABLE OF PRODUCING TORNADOES, DAMAGING GUSTS, AND MARGINALLY SEVERE HAIL. THE CONVECTION WILL SUBSEQUENTLY SPREAD NORTHEASTWARD TOWARD LOWER MI LATER THIS AFTERNOON. THE DEGREE OF DESTABILIZATION IS MORE QUESTIONABLE COMPARED TO AREAS FARTHER SOUTHWEST, BUT WIND PROFILES WILL STRONGLY FAVOR ORGANIZED/SUPERCELL STORMS. ..THOMPSON/BENTLEY.. 03/14/2019 Link to comment Share on other sites More sharing options...

Hoosier Posted March 14, 2019 Share Posted March 14, 2019 Ominous look on visible satellite imagery in IL. Low level moisture still lacking a bit toward Chicago but there is still some time and we probably won't even need to get dewpoints into the 60s to have problems given the steep mid level lapse rates with partial clearing.

janetjanet998 Posted March 14, 2019 Share Posted March 14, 2019 instead of having 3 seperate threads might as well make this the main sever thread for the day...... so.. ESOSCALE DISCUSSION 0208 NWS STORM PREDICTION CENTER NORMAN OK 1147 AM CDT THU MAR 14 2019 AREAS AFFECTED...NORTHEAST MISSISSIPPI...NORTHWEST ALABAMA...AND SOUTHERN TENNESSEE CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY VALID 141647Z - 141815Z PROBABILITY OF WATCH ISSUANCE...80 PERCENT SUMMARY...A GRADUAL INCREASE IN STORMS IS EXPECTED THROUGH THE AFTERNOON. A TORNADO WATCH WILL LIKELY BE NEEDED SOON. DISCUSSION...16Z SURFACE ANALYSIS SHOWS MUCH OF NORTHEAST MISSISSIPPI AND NORTHWEST ALABAMA HAS WARMED 4 TO 5 F IN THE LAST HOUR DESPITE SOME CLOUD COVER ACROSS THE AREA. THIS HAS LED TO AN INCREASE IN LOW-LEVEL INSTABILITY TO AROUND 750 TO 1000 J/KG OF MLCAPE. WARMING IS EXPECTED TO CONTINUE WITH LOW-LEVEL MOISTURE ADVECTION WHICH WILL LEAD TO MODERATE INSTABILITY BY MID-AFTERNOON. THE RECENT HEATING IN THIS AREA HAS PROVIDED ENOUGH INSTABILITY FOR A REINVIGORATION OF LIGHTNING FROM SOME OF THE CONVECTION IN NORTHERN MISSISSIPPI. THEREFORE, EXPECT MORE WIDESPREAD STORM COVERAGE WITHIN THE NEXT HOUR OR TWO AS SURFACE DESTABILIZATION CONTINUES TO INCREASE. DEEP-LAYER SHEAR IN THIS AREA IS VERY FAVORABLE FOR SUPERCELL AND LOW-LEVEL MESOCYCLONE DEVELOPMENT WITH DEEP LAYER EFFECTIVE SHEAR AROUND 55 TO 60 KNOTS AND 0-1 SRH AROUND 350 M2/S2 PER GWX VWP. THEREFORE, THESE STORMS WILL POSE A TORNADO THREAT WITH THE POTENTIAL FOR STRONG TORNADOES, ESPECIALLY AS SUPERCELLS MATURE INTO NORTHWEST ALABAMA.

CryHavoc Posted March 14, 2019 Share Posted March 14, 2019 In fairness to the NWS, this is not your usual synoptic setup with the bomb cyclone moving through. Definitely a lot of factors went into the ingredients today to giving those cells the ability to rotate. Link to comment Share on other sites More sharing options...
DanLarsen34 Posted March 14, 2019 Share Posted March 14, 2019 If storm evolution in real time is favorable before the mid afternoon update, wouldn’t be surprised to see a moderate for some part of the enhanced tornado risk area. Link to comment Share on other sites More sharing options...
NTXYankee Posted March 14, 2019 Share Posted March 14, 2019 Per visible a nice clearing is headed to CMH. We’ve had very little in the way of rain today except this morning early. Thinking Ohio is going to be a surprise later. Link to comment Share on other sites More sharing options...
