DISCUSSION
KEY MESSAGE 1...
THE UPPER LOW REMAINS JUST EAST OF THE LAKES ASSISTING IN THE
NORTHERLY TO NNW-ERLY WIND DIRECTIONS CONTINUING TO ADD TO AN
ENHANCED PORTION TO THE SNOW BANDS OFF THE LAKE. THUS, WILL
EXPECTED TO KEEP POPS IN THE FORECAST OVER THE LOW LANDS AND
RIDGES INTO THE OVERNIGHT. THE ADVISORIES AND WINTER STORM
WARNINGS HAVE BEEN LEFT ALONE AND WILL RUN INTO THE EVENING. THE
HI-RES MODELS ALONG WITH A FAVORABLE WIND DIRECTION HAVE HINTED
ON A SNOW BAND TO DEVELOP TONIGHT THAT LINKS UP TO LAKE HURON.
THIS BAND MAY PRODUCE SOME ADDITIONAL ACCUMULATIONS THIS EVENING
INTO TONIGHT.
THE ADDITIONAL PUSH FROM THE LAKES COULD PUSH THE SNOW AMOUNTS
OVER THE NEEDED THRESHOLD OF 6 INCHES IN THE INDIANA, WESTMO,
AND FAYETTE RIDGES. THE HEADLINES EXPIRE BY 06Z TONIGHT.
KEY MESSAGE 2...
A BRIEF STAY OF HIGH PRESSURE TUESDAY IS QUICKLY CHASED AWAY BY
A SHORTWAVE CRASHING THROUGH THE UPPER OHIO VALLEY TUESDAY
NIGHT INTO WEDNESDAY MORNING. AT THE SURFACE AN ACCOMPANYING LOW
SWINGS THROUGH THE GREAT LAKES PUSHING A SERIES OF FRONTS
THROUGH THE REGION. THE LEFT EXIT REGION OF AN UPPER JET STREAK
AND RATHER STOUT MID-LEVEL WAA LOOK TO BRING A QUICK BURST OF
SNOW ACROSS THE REGION. THE ONLY CONCERN IN THE LATEST RUN, IS
THAT THE TROUGH HAS TAKEN A BIT NORTH IN THE TRACK AND THAT HAS
SHAVED AN INCH OR TWO OFF THE TOTALS IN THE NORTHEASTERN
FORECAST AREA. THIS TREND WILL LEAD TO CONCERNS BECAUSE THE
PROBABILITY OF EXCEEDANCE IN THESE AREAS FOR ADVISORY CRITERIA
IS NEAR 60% TO 75%. SO THIS WILL NEED MONITORING AS THE WARMING
ROAD TEMPERATURES AND THE POTENTIAL CHANGE IN TRACK MIGHT
SIGNIFICANTLY IMPACT THESE TOTALS.
KEY MESSAGE 3...
A THIRD UPPER SHORTWAVE CROSSES THE MIDWEST AND ROUNDS ITS WAY
TOWARDS THE OHIO VALLEY WEDNESDAY INTO THURSDAY. AT THE SURFACE,
A DEEPENING LOW IS PROGGED TO CROSS THE OHIO VALLEY DURING THE
DAY THURSDAY. THERE REMAIN SOME NORTH-SOUTH PLACEMENT
DIFFERENCES IN THE ENSEMBLES THIS FAR OUT BUT A TRACK DIRECTLY
OVER (MIXED PRECIPITATION) OR EVEN NORTH OF PITTSBURGH (MAINLY
RAIN) SEEMS TO BE FAVORED OVER ANY SNOWIER SOUTHERN SOLUTIONS.
WE WILL KEEP AN EYE ON UPCOMING FORECAST TRENDS BUT AT THIS
TIME, WITH A MIX OR MOSTLY RAIN FAVORED, THE PROBABILITY OF
IMPACTFUL SNOW ACCUMULATIONS LOOKS LOW.
