VALID 210254Z - 210430Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 157 CONTINUES. SUMMARY...THE SEVERE THREAT CONTINUES ACROSS TORNADO WATCH 157. A COUPLE OF SEVERE GUSTS ARE THE MAIN CONCERN, THOUGH A TORNADO CANNOT BE RULED OUT. DISCUSSION...A PRIMARY BAND OF CONVECTION PERSISTS AMID VERY STRONG FORCING ACCOMPANYING AN APPROACHING SURFACE LOW AND UPPER-LEVEL JET STREAK. DESPITE SCANT BUOYANCY, THE LATEST LOT VAD SHOWS A HODOGRAPH WITH IMPRESSIVE SIZE AND CURVATURE, INDICATING STRONG LOW-LEVEL WIND SHEAR, DRIVEN BY VERY STRONG FLOW JUST ABOVE THE SURFACE. WHILE DECREASING LIGHTNING TRENDS SUGGEST THAT STORMS ARE WEAKENING, THE INTENSE LOW-LEVEL FLOW/SHEAR SUGGESTS THAT DAMAGING GUSTS MAY STILL OCCUR WHEREVER DOWNWARD MOMENTUM TRANSPORT MAY OCCUR. A TORNADO ALSO REMAINS POSSIBLE IF A ROTATING UPDRAFT CAN INGEST ANY REMAINING SURFACE-BASED BUOYANCY. ..SQUITIERI.. 04/21/2025 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...

SEVERE THUNDERSTORMS WILL SPREAD ACROSS THE MID MISSISSIPPI VALLEY INTO WESTERN TENNESSEE THIS EVENING. A FEW TORNADOES REMAIN POSSIBLE, ALONG WITH THE THREAT OF WIND AND PERHAPS SOME HAIL. ...01Z UPDATE... STRONG NEGATIVE-TILT SHORT-WAVE TROUGH IS EJECTING NORTHEAST ACROSS EASTERN KS/WESTERN MO EARLY THIS EVENING. THIS FEATURE IS CONTRIBUTING TO AN ELONGATED BAND OF CONVECTION THAT CURRENTLY ARCS FROM WESTERN IL-SOUTHEAST MO-CENTRAL AR-SOUTHEAST TX, COINCIDENT WITH THE PRIMARY SYNOPTIC COLD FRONT SURGING EAST. OVER THE LAST FEW HOURS THE MOST CONCENTRATED CORRIDOR OF SUPERCELLS HAS SHIFTED INTO EASTERN AR WHERE NO LESS THAN FOUR DISTINCT SUPERCELLS ARE SPREADING ACROSS WESTERN PORTIONS OF WW156. LATEST MODEL GUIDANCE SUGGESTS THE LLJ WILL INCREASE ACROSS NORTHERN MS/WESTERN TN/KY LATER THIS EVENING. THERE IS SOME CONCERN THIS ACTIVITY MAY SPREAD A BIT FARTHER DOWNSTREAM THAN DEPICTED IN EARLIER DAY1 CONVECTIVE OUTLOOK. FORECAST SOUNDING FOR MEM AT 06Z EXHIBITS MORE THAN ADEQUATE SBCAPE FOR ROBUST UPDRAFTS, AND STRONG SHEAR IS FAVORABLE FOR THE MAINTENANCE OF THESE STORMS. WILL ADJUST THE SLGT/MRGL RISKS EAST TO ACCOUNT FOR THIS SCENARIO. ..DARROW.. 04/21/2025 READ MORE =#=#=#=#=#=#=#=#= +----------------------------------------------------------------------------+ HYPERTEXT PREPROCESSOR - DEVELOPED BY LU9DCE - VERSION 3
