DISCUSSION
KEY MESSAGE 1)
WEST TO NORTHWEST FLOW ALOFT WILL LEAD TO AN ACTIVE WEATHER PATTERN
THROUGH AT LEAST MID WEEK AND POSSIBLY LINGERING INTO THE LATER PART
OF THE WEEK.
THE AIRMASS ACROSS OUR AREA HAS DESTABILIZED NICELY AGAIN THIS
AFTERNOON, WITH AN AXIS OF MLCAPES OF 2000 J/KG OR SO RUNNING
NORTHWEST TO SOUTHEAST ACROSS OUR AREA. THIS IS RESULTING IS A TIGHT
INSTABILITY GRADIENT STRETCHING FROM FAR NORTHWEST INDIANA DOWN
ACROSS NORTHERN OHIO. THERE IS SOME UNCERTAINTY AS TO HOW WELL THE
STORMS CURRENTLY UP TOWARD SOUTHERN LAKE MICHIGAN WILL HOLD
TOGETHER, BUT IF THEY DO, THEY COULD TRACK EAST SOUTHEAST ALONG THE
GRADIENT AND TOWARD OUR AREA LATE THIS AFTERNOON INTO EARLY EVENING.
WILL GO AHEAD AND INCLUDE SOME LOWER END POPS ACROSS OUR FAR NORTH
THIS EVENING TO ACCOUNT FOR THIS POSSIBILITY.
A STRENGTHENING LOW LEVEL JET LATER TONIGHT WILL LIKELY LEAD TO SOME
ADDITIONAL REDEVELOPMENT OFF TO OUR NORTHWEST. SEVERAL OF THE HI-
RES MODELS ARE SUGGESTING THIS ACTIVITY WILL THEN DROP EAST-
SOUTHEAST INTO OUR AREA LATE TONIGHT INTO EARLY MONDAY MORNING. WITH
THIS BEING DURING A LESS FAVORABLE TIME OF DAY, WOULD GENERALLY
EXPECT A WEAKENING TREND WITH ANY STORMS THAT DO MAKE IT INTO OUR
AREA, BUT SUPPOSE IT WILL BE TOUGH TO RULE OUT A LOW END
SEVERE/DAMAGING WIND THREAT, ESPECIALLY ACROSS NORTHWEST PORTIONS OF
OUR AREA.
REMNANTS FROM THE POTENTIAL MORNING ACTIVITY COULD INITIALLY AFFECT
TEMPERATURES. HAVE MADE SOME MINOR DOWNWARD ADJUSTMENTS TO
TEMPERATURES AS A RESULT, BUT WE WILL STILL BE QUITE HUMID WITH
AFTERNOON HEAT INDICES IN THE 95 TO 100 DEGREE RANGE. THIS WOULD
STILL ALLOW FOR A FAIR AMOUNT OF DESTABILIZATION THROUGH THE DAY SO
ADDITIONAL SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE LATER MONDAY
AFTERNOON AND INTO THE OVERNIGHT HOURS AS A WEAK FRONTAL BOUNDARY
PUSHES SOUTH TOWARD OUR AREA. WITH STRENGTHENING LOW/MID LEVEL FLOW,
SOME SEVERE STORMS WILL AGAIN BE POSSIBLE. DAMAGING WIND WILL BE THE
PRIMARY THREAT, ALTHOUGH INCREASING LOW LEVEL SHEAR COULD ALSO LEAD
TO A LOWER END TORNADO THREAT, ESPECIALLY FOR AREAS ALONG AND NORTH
OF THE I-70 CORRIDOR.
IN THE PERSISTENT NORTHWEST FLOW ALOFT, ADDITIONAL ROUNDS OF SHOWERS
AND STORMS WILL BE POSSIBLE TUESDAY AND WEDNESDAY AS THE FRONTAL
BOUNDARY CONTINUES TO SAG SLOWLY SOUTH INTO OUR AREA. A CHANCE FOR
PRECIPITATION WILL LINGER INTO THURSDAY AND POSSIBLY FRIDAY, WITH
THE BEST CHANCES ACROSS OUR SOUTHERN AREAS, CLOSER TO THE REMNANT
BOUNDARY.
WITH HIGH SUMMERTIME PWS IN PLACE AND REPEATED ROUNDS OF STORMS
POSSIBLY TRACKING OVER THE SAME LOCATIONS, FLOODING CONCERNS WILL
INCREASE AS WE PROGRESS INTO MID WEEK.
AVIATION /18Z SUNDAY THROUGH FRIDAY/
SOME LOCALIZED MVFR STRATOCU WILL BE POSSIBLE FOR THE NEXT HOUR OR
TWO. OTHERWISE, GENERALLY EXPECT JUST SCT-BKN VFR CU THROUGH THE
REMAINDER OF THE AFTERNOON. A SERIES OF CONVECTIVE COMPLEXES OFF TO
OUR NORTHWEST WILL DROP SOUTHEAST INTO OUR AREA THIS EVENING AND
OVERNIGHT INTO MONDAY MORNING. THERE IS SOME UNCERTAINTY AS TO HOW
WELL THESE WILL HOLD TOGETHER THOUGH, SO WILL GENERALLY JUST INCLUDE
A PROB30 AT THE TAF SITES DURING THE MOST FAVORABLE TIME. WE SHOULD
THEN GET INTO A LULL IN PCPN LATER MONDAY MORNING INTO EARLY
AFTERNOON, BUT ADDITIONAL REDEVELOPMENT WILL BE POSSIBLE LATER IN THE
DAY. WILL COVER THIS THREAT WITH A PROB30 IN THE TAIL END OF THE 30
HOUR KCVG TAF.
OUTLOOK...THUNDERSTORMS ARE POSSIBLE AT TIMES THROUGH THURSDAY.
