CONCERNING...SEVERE THUNDERSTORM WATCH 97...
VALID 042255Z - 050030Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 97
CONTINUES.
SUMMARY...FORCED CONVECTION CONTINUES IN A COUPLE OF BANDS ACROSS
OHIO THIS EVENING. THE OVERALL ENVIRONMENT SHOULD CONTINUE TO
STABILIZE WITH THE LOSS OF DIURNAL HEATING, BUT A SEVERE GUST OR
BRIEF TORNADO REMAINS POSSIBLE FOR ANOTHER COUPLE OF HOURS.
DISCUSSION...TWO NARROW BANDS OF CONVECTION CONTINUE TO MOVE ACROSS
PORTIONS OF SEVERE THUNDERSTORM WATCH #97. THE LEADING BAND,
STRETCHING FROM NEAR CLEVELAND, OH, TO NEAR COLUMBUS, OH, IS BEING
FORCED ON A PRE-FRONTAL BAND OF ASCENT PERHAPS ASSOCIATED WITH A
COLD FRONT ALOFT. THE ENVIRONMENT ALONG AND AHEAD OF THIS BAND IS
STABILIZING AS EVIDENCED BY RECENT OBJECTIVELY ANALYZED MUCAPE
FIELDS FALLING TO BETWEEN 500 AND 1000 J/KG AND MLCAPE INCREASINGLY
LESS THAN 100 J/KG. CONTINUED STABILIZATION OF THE LOWER LEVELS WILL
TEMPER A MORE WIDESPREAD SEVERE EVENT DESPITE FAVORABLE LOW LEVEL
KINEMATIC FIELDS. THAT SAID, A SEVERE THUNDERSTORM WIND GUST OR TWO
MAY REMAIN POSSIBLE FOR THE NEXT COUPLE OF HOURS GIVEN THE STRENGTH
OF THE LOW-LEVEL FLOW.
TO THE WEST OF THIS FIRST BAND, A SECOND BAND OF CONVECTION
STRETCHES FROM THE WESTERN EDGE OF LAKE ERIE TO NEAR DAYTON, OH.
THIS BAND IS BEING DRIVEN BY LOW-LEVEL CONVERGENCE ALONG THE SURFACE
FRONT. INSTABILITY IS RATHER LIMITED AHEAD OF THIS LINE, BUT GIVEN
THE INCREASED SURFACE VORTICITY ALONG THE COLD FRONT AND STRONG
LOW-LEVEL FLOW, A DAMAGING WIND GUST OR BRIEF TORNADO MAY STILL BE
POSSIBLE, AS SUPPORTED BY SEVERAL SMALL-SCALE CIRCULATIONS WITHIN
THE LAST HOUR ACROSS SOUTHEAST LOWER MICHIGAN.
WITH BOTH BANDS, CONVECTIVE TRENDS WILL BE MONITORED AND UNLESS
ACTIVITY STRENGTHENS IN THE NEXT HOUR OR SO, ALL OR PORTIONS OF THE
SEVERE THUNDERSTORM WATCH MAY BE CANCELED EARLY.
