&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
TWO WEATHER FEATURES FOR THE FORECAST TONIGHT...A COLD FRONT MOVING
THROUGH THIS EVENING AND THEN AN UPPER LOW WILL PASS WELL TO THE
NORTH OF THE FORECAST AREA LATE TONIGHT.

A WEAK TROUGH MOVING THROUGH ATTM...SOME SHOWERS AND
THUNDERSTORMS COULD DEVELOP WITH IT BUT THE MAIN ACTIVITY WILL BE
SHOWERS AND THUNDERSTORMS AHEAD OF THE FRONT...MAINLY STRONG WINDS
WITH IT AND POSSIBLY SOME HAIL. INVERTED V SOUNDING. SPC IS
FAIRLY CONFIDENT A WATCH WILL BE NEEDED BY 21Z.

MORE THAN LIKELY BEHIND THE FRONT...COULD BE A SHORT PERIOD OF
SOME SHOWERS. CLOUD COVER MAY BE VARIABLE WITH A BREAK AFTER THE
FRONTAL PASSAGE AND THE CLOUDS FROM THE UPPER LOW. WENT WITH THE
WARMER GUIDANCE ESPECIALLY ALONG THE LAKE SHORE BECAUSE OF ONSHORE
FLOW.

RAINFALL AT MOST LOCATIONS SHOULD BE UNDER HALF AN INCH TONIGHT.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY NIGHT/...
UPDATED TO ADD THE WATCH.

HIGH PRESSURE BUILDING IN FOR THURSDAY...PLENTY OF LOW LEVEL
MOISTURE...SKIES WILL BE PARTLY TO MOSTLY SUNNY...THE BEST CHANCE
FOR CLOUDS WILL BE OVER THE EASTERN PORTION OF THE FORECAST AREA.
WENT WITH THE WARMER GUIDANCE FOR TEMPERATURES BECAUSE OF PLENTY OF
SUN.

MOSTLY CLEAR AND DRY THURSDAY NIGHT. INCREASING CLOUDS
FRIDAY...TIMING OF THE LOW AND FRONT IS STILL IN QUESTION. WILL GO A
LITTLE SLOW BUT TRY TO EMPHASIZE THE AFTERNOON. PLENTY OF COLD AIR
FOR THE WEEKEND. THE GFS IS A FEW DEGREES COLDER AND THE LAKE AND
850 MB TEMPERATURE DIFFERENCE WILL BE NEAR 16C...ENOUGH FOR SOME
LAKE EFFECT SHOWERS. HIGH PRESSURE IS TRYING TO BUILD IN WITH SOME
RIDGING BUT THAT SHOULD ONLY HAVE A MINOR IMPACT ON THE ACTIVITY.
BECAUSE OF PLENTY OF CLOUDS EXPECTED DID A BLEND BETWEEN THE MAV AND
NAM MOS FOR HIGHS FRIDAY.

SOME LAKE EFFECT SHOWERS WILL OCCUR OVER THE SNOW BELT SATURDAY
INTO SATURDAY NIGHT. THE ECMWF IS WARMER AND KEEPS THE
PRECIPITATION SATURDAY NIGHT ALL RAIN WHILE THE GFS HAS A MIX.

INTO THURSDAY.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
COLD FRONT IS NEAR THE I-71 CORRIDOR. A BROKEN LINE OF CONVECTION
CONTINUES ALONG THE FRONT. THERE HAS BEEN SOME DECREASE IN
INTENSITY THE PAST HOUR OR SO. THE STRONGEST STORM IS NOW JUST SW
OF KFDY AND COULD AFFECT KMFD IN AN HOUR OR TWO IF IT MAINTAINS
ITSELF. ANOTHER BROKEN LINE OF SHOWERS AND STORMS HAS DEVELOPED
OVER NW OH. THIS ACTIVITY IS LIKELY ASSOCIATED WITH THE UPPER
TROUGH TRAILING THE COLD FRONT. IT WILL TAKE MOST IF NOT THE
REMAINDER OF THE EVENING FOR ALL OF THIS ACTIVITY TO MAKE IT OUT
OF THE AREA. WILL GIVE MOST LOCATIONS A COUPLE HOUR PERIOD OF
THUNDER FOLLOWED BY ANOTHER HOUR OR TWO OF SHOWERS. WINDS WILL
INITIALLY BECOME NW BEHIND THE FRONT BUT WILL BECOME W TO SW BY
06Z. SW FLOW WILL REMAIN GUSTY AHEAD OF THE COLD FRONT. CIGS AND
