BROAD MID AND UPPER LEVEL RIDGE TO SHIFT EAST AND FLATTEN AS
SHORTWAVE ENERGY PASSES THRU THE GREAT LAKES OVERNIGHT THRU SATURDAY.
INITIAL SHORTWAVE PASSES TO OUR NORTH WITH CONVECTION THAT DEVELOPS
IN THE UPPER MIDWEST TONIGHT TRACKING SOUTHEAST AND WEAKENING AS IT
APPROACHES THE REGION TOWARD DAYBREAK SATURDAY. THIS CONVECTION WILL
HAVE DECREASING CHANCES FOR THUNDER AS IT DROPS INTO OUR NORTHERN
COUNTIES SATURDAY MORNING.
AFTER THE MORNING CLOUDS CLEAR THE AIRMASS WILL RECOVER WITH MODERATE
INSTABILITY EXPECTED SATURDAY AFTERNOON. MODEL SOLUTIONS CONTINUE TO
SHOW A WIDE ARRAY OF POSSIBLE OUTCOMES - THEREFORE UNCERTAINTY IS
HIGH. FOLLOWING A CONSENSUS SOLUTION WITH THE MODERATE INSTABILITY
DEVELOPING DURING THE AFTERNOON - THE MOST FAVORED AREA FOR THE
DEVELOPMENT OF DEEP CONVECTION IS ALONG AND NORTH OF I-70. WITH THE
TAIL OF WEAKENING JET PIVOTING THRU CENTRAL OHIO, THIS WILL BE THE
MOST FAVORED REGION FOR ORGANIZED CONVECTION DURING THE LATE
AFTERNOON AND INTO THE EVENING. DAMAGING WIND GUSTS WILL BE THE
PRIMARY THREAT. CANNOT RULE OUT ISOLATED LARGE HAIL OR EVEN A
TORNADO.
KEY MESSAGE 2)
A SKINNY NARROW MID LEVEL RIDGE BUILDS INTO THE REGION SUNDAY INTO
EARLY NEXT WEEK. A SYSTEM LIFTS NORTHEAST ON THE BACK SIDE OF THIS
RETREATING RIDGE BRINGING INCREASED CHANCES FOR SHOWERS AND
THUNDERSTORMS MONDAY AND TUESDAY.
A BROAD MID LEVEL RIDGE THEN LOOKS TO BUILD INTO THE REGION FOR LATE
WEEK INTO NEXT WEEKEND. THIS WILL ALLOW TEMPERATURES AND DEW POINTS
TO INCREASE WITH THE POTENTIAL FOR IMPACTFUL WEATHER DUE TO HEAT.
