DISCUSSION
KEY MESSAGE 1)
SHALLOW MID/UPPER LEVEL TROUGHING WILL SHIFT SLOWLY EAST ACROSS THE
GREAT LAKES REGION THROUGH THE END OF THE WEEK. AS IT DOES, SEVERAL
EMBEDDED IMPULSES WILL MOVE THROUGH THE TROUGH. THIS WILL LEAD TO
OCCASIONAL CHANCES FOR SHOWERS AND THUNDERSTORMS OVER THE NEXT
SEVERAL DAYS.
THE FIRST CHANCE FOR PRECIPITATION WILL BE WEDNESDAY AS AN
INSTABILITY GRADIENT DEVELOPS ACROSS EASTERN PORTIONS OF OUR AREA.
WHILE FORCING IS LIMITED, INSTABILITY SHOULD BE SUFFICIENT ENOUGH
FOR AT LEAST SCATTERED THUNDERSTORM DEVELOPMENT THROUGH THE AFTERNOON
AND LINGERING INTO THE EVENING. GIVEN THE WEAK FORCING AND LIGHT
FLOW, THE SEVERE THREAT WILL BE LOW, BUT LIGHT FLOW/SLOW STORM
MOVEMENT WILL LEAD TO THE POTENTIAL FOR LOCALLY HEAVY DOWNPOURS.
BETTER CHANCES FOR SHOWERS AND THUNDERSTORMS WILL DEVELOP THURSDAY
INTO FRIDAY AND CONTINUING INTO THE WEEKEND AS SOMEWHAT STRONGER
IMPULSES BEGIN TO MOVE THROUGH THE TROUGH. THIS WILL ALSO RESULT IN
SOMEWHAT BETTER MID LEVEL WIND FIELDS/DEEPER LAYER SHEAR. THIS WOULD
SUPPORT THE POTENTIAL FOR A FEW STRONGER TO POSSIBLY SEVERE STORMS
AS WE PROGRESS THROUGH THE WEEK.
AVIATION /00Z WEDNESDAY THROUGH SUNDAY/
THERE WILL BE THE POTENTIAL FOR SOME FOG OVERNIGHT. HAVE REDUCED
VISIBILITIES IN AT KCVG, KLUK, KILN, AND KLCK. SOME ISOLATED TO
SCATTERED THUNDERSTORMS WILL DEVELOP FOR THE DAY ON WEDNESDAY. WHILE
MOST OF THE ACTIVITY WILL BE EAST OF THE TAF SITES, KCMH, KLCK, AND
KILN WILL BE ON THE EDGE OF THIS ACTIVITY. DUE TO THIS, LIMITED
THUNDERSTORM POTENTIAL TO A PROB30. WINDS WILL GENERALLY BE LIGHT
AND LESS THAN 10 KNOTS THROUGH THE TAF PERIOD.
OUTLOOK...THUNDERSTORMS ARE POSSIBLE AT TIMES THROUGH SUNDAY.
