...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE CENTRAL
HIGH PLAINS TO THE TENNESSEE VALLEY...
..SUMMARY
CLUSTERS OF THUNDERSTORMS ACCOMPANIED BY A RISK FOR DAMAGING WIND
GUSTS MAY EVOLVE IN A CORRIDOR ACROSS PARTS OF THE CENTRAL AND
SOUTHERN GREAT PLAINS INTO THE TENNESSEE VALLEY FRIDAY AFTERNOON AND
EVENING.
..CENTRAL/SOUTHERN PLAINS TO OH/TN VALLEYS
WEAK UPPER TROUGHING WILL SHIFT EAST FROM THE MIDWEST TO THE
ATLANTIC COAST ON FRIDAY. MEANWHILE, A CONVECTIVELY ENHANCED
MIDLEVEL DISTURBANCE WITHIN LARGER-SCALE UPPER RIDGING OVER THE
PLAINS MAY MOVE ACROSS PORTIONS OF THE CENTRAL/SOUTHERN PLAINS TO
THE MID-MS VALLEY. ADDITIONALLY, IT IS POSSIBLE AN MCV MAY BE
LOCATED IN THE VICINITY OF THE LOWER OH VALLEY, RELATED TO REMNANT
CONVECTION FROM THE DAY 2/THURSDAY PERIOD. WITHIN THIS CORRIDOR FROM
EASTERN CO THROUGH PORTIONS OF TN/KY, A SEASONALLY MOIST AND
UNSTABLE AIRMASS WILL BE IN PLACE. ONE OR MORE OUTFLOW BOUNDARIES
ARE ALSO LIKELY TO OVERLAP THIS ZONE. MODESTLY ENHANCED WESTERLY
FLOW ATOP THIS MOIST/UNSTABLE CORRIDOR MAY PROMOTE SEVERAL
THUNDERSTORM CLUSTERS CAPABLE OF PRODUCING MAINLY STRONG TO SEVERE
WIND GUSTS. WHERE THESE CLUSTERS DEVELOP WILL LARGELY BE DRIVEN BY
MESOSCALE PROCESSES AND CONVECTIVE EVOLUTION IN THE DAY 2/THURSDAY
PERIOD. GIVEN UNCERTAINTY IN LOCATION OF VARIOUS SURFACE FEATURES AT
THIS TIME FRAME, WILL MAINTAIN A BROAD MARGINAL (LEVEL 1 OF 5) RISK
AREA FOR FRIDAY AFTERNOON/EVENING FROM THE CENTRAL HIGH PLAINS TO
THE LOWER OH AND TN VALLEYS.
