HIGHLY AMPLIFIED MID LEVEL FLOW WITH DEEP LOW PRESSURE OFF THE MID
ATLANTIC COAST PLACING THE OHIO VALLEY IN NORTHERLY FLOW. IMPULSES
EMBEDDED IN THE FLOW TO DROP THRU THE AREA THIS MORNING. STEEP LOW
LEVEL LAPSE RATES WITH THE SATURATED LAYER IN THE FAVORABLE DGZ WILL
CONTINUE TO BE FAVORABLE FOR SNOW SHOWERS. THESE SNOW SHOWERS WILL BE
ENHANCED WITH FLOW OFF THE GREAT LAKES. NBM MODEL TENDS TO STRUGGLE
ENDING SNOW SHOWERS TOO SOON IN THESE SITUATIONS. THEREFORE POPS HAVE
BEEN INCREASED TO REFLECT THIS POTENTIAL THRU THE MORNING. HREF
SHOWS 60 TO 70 PERCENT PROBABILITY OF A HALF INCH OR MORE OF SNOW
ACROSS PORTIONS OF CENTRAL OHIO. FOR THE FORECAST HAVE ANY ADDITIONAL
ACCUMULATION UP TO AROUND A HALF INCH WITH THIS BEST POTENTIAL
ACROSS CENTRAL OHIO. WITH ROAD TEMPERATURES BELOW FREEZING
- SLICK SPOTS WILL REMAIN POSSIBLE. ALSO, NORTHWEST WIND GUSTS WILL
RESULT IN BLOWING AND DRIFTING SNOW. HAVE AN SPS TO HIGHLIGHT THE
TRAVEL IMPACTS FOR THIS MORNINGS COMMUTE.
KEY MESSAGE 2)
MODEL SOLUTIONS HAVE TRENDED FARTHER SOUTH WITH SYSTEM TRACKING
THROUGH THE REGION AT MID WEEK. LATEST ENSEMBLE SOLUTIONS BRING A
LOW PRESSURE SYSTEM THROUGH SOUTHERN PORTIONS OF THE OHIO VALLEY
LATE WEDNESDAY INTO THURSDAY. RETURN FLOW LOOKS TO BRING A SURGE IN
DEEPER MOISTURE NORTH JUST AHEAD OF THE SYSTEM. THERE IS STILL LARGE
SPREAD IN SOLUTIONS AND THEREFORE A GOOD DEAL OF UNCERTAINTY. THIS
SOUTHERN TREND ALLOWS FOR MORE SNOW POTENTIAL ALONG AND NORTH OF I-70
WHERE THE POTENTIAL EXISTS FOR SEVERAL INCHES OF SNOW. NBM INDICATES
A 20 PERCENT CHANCE FOR SNOW ACCUMULATION ABOVE 3 INCHES ACROSS ILN/S
EXTREME NORTHERN COUNTIES. WHILE PWATS INCREASE THE LATEST SOLUTIONS
HAVE LESS OF AN ANOMALY WITH VALUES 150 TO 200 PERCENT OF NORMAL
ACROSS THE SOUTH. THE SYSTEM IS PROGRESSIVE WITH RAINFALL APPROACHING
AN INCH POSSIBLE ACROSS NORTHERN KY AND ALONG THE OHIO RIVER.

BE FAVORABLE FOR SNOW SHOWERS. THESE SNOW SHOWERS WILL BE ENHANCED
WITH FLOW OFF THE GREAT LAKES. SNOW SHOWERS WILL REDUCE VISIBILITIES
