DISCUSSION
KEY MESSAGE 1)
SOUTHERLY FLOW AND WARM CONDITIONS WILL BE OBSERVED TODAY AHEAD OF A
COLD FRONT THAT SLIPS INTO NORTHERN OHIO AND STALLS PARALLEL TO THE
WESTERLY MID LEVEL FLOW. IT IS NOT OUT OF THE QUESTION THAT A FEW
LIGHT SHOWERS COULD MAKE IT AS FAR SOUTH AS ILN/S NORTHERN COUNTIES
LATE IN THE DAY. HIGHS TOP OUT IN THE MID AND UPPER 70S TODAY - WHICH
LOOK TO BE 10 TO 15 DEGREES ABOVE NORMAL. IN THE WELL MIXED BOUNDARY
LAYER SOUTHWEST WINDS TO GUST TO 25 TO 30 MPH THIS AFTERNOON.
MID LEVEL ENERGY PASSING THRU THE GREAT LAKES WILL LEAD TO THE
DEVELOPMENT OF A WEAK SURFACE LOW WITH A TRAILING WEAK FRONT PASSING
THRU ILN/S AREA FRIDAY INTO FRIDAY NIGHT. SOUTHWEST LOW LEVEL FLOW
AHEAD OF THIS FRONT WILL LEAD TO AN INCREASE IN MOISTURE WITH
MARGINAL INSTABILITY DEVELOPING. HAVE A SLIGHT CHANCE MENTION OF
THUNDER DUE TO THIS LIMITED INSTABILITY. HAZARDOUS WEATHER CONTINUES
TO LOOK UNLIKELY.
SURFACE HIGH PRESSURE WILL BUILD INTO THE GREAT LAKES IN THE WAKE OF
THE FRONT FRIDAY NIGHT INTO SATURDAY. THIS HIGH WILL OFFER DRY AND
COOLER WEATHER SATURDAY - WITH HIGHS RANGING FROM THE LOWER 60S NORTH
TO THE LOWER 70S SOUTH.
MID LEVEL FLOW AMPLIFIES WITH A MEAN RIDGE DEVELOPING OVER THE
EASTERN CONUS. A PROLONGED PERIOD OF SOUTHERLY TO SOUTHWESTERLY
FLOW IS EXPECTED FOR SEVERAL DAYS, BRINGING HIGHS INTO THE 80S.
THERE IS HIGH CONFIDENCE IN THIS PERIOD OF WARM TEMPERATURES.
CONSIDERABLY LOWER CONFIDENCE EXISTS REGARDING RAIN TIMING AND
CHANCES THRU THIS PERIOD. IT DOES LOOK LIKE A THREAT FOR SHOWERS AND
STORMS WILL EXIST BEGINNING MONDAY AND BEYOND AS WAVES TRACK AROUND
THE PERIPHERY OF THE MID LEVEL RIDGE BUT SPECIFIC DETAILS ARE
SOMEWHAT UNCERTAIN AT THIS TIME.
AVIATION /10Z THURSDAY THROUGH MONDAY/
VFR CONDITIONS ARE EXPECTED THROUGH THE TAF PERIOD. ANY PRECIPITATION
THAT MAY DEVELOP LATER IN THE AFTERNOON WILL STAY NORTH OF THE TAF
SITES. SOME HIGH LEVEL CLOUDS WILL MOVE ACROSS THE TAF SITES AT
TIMES THROUGH THE TAF PERIOD. ALSO, A FEW CUMULUS CLOUDS WILL BE
LIKELY DURING AFTERNOON. THERE WILL BE THE POTENTIAL FOR A PERIOD OF
LLWS EARLY THIS MORNING AT KCVG, KLUK, AND KDAY. SURFACE WINDS WILL
INCREASE THIS AFTERNOON WITH GUSTS UP TO 25 KTS.
OUTLOOK...MVFR CONDITIONS POSSIBLE FRIDAY AFTERNOON INTO FRIDAY
NIGHT AND THEN AGAIN ON MONDAY. WIND GUSTS AROUND 30 KNOTS POSSIBLE
ON MONDAY.
