AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
1250 PM EST MON JAN 26 2015

.SYNOPSIS...
LOW PRESSURE WILL QUICKLY MOVE AWAY FROM THE REGION THIS MORNING.
HIGH PRESSURE WILL THEN BUILD IN THROUGH THE MIDDLE OF THE WEEK.
ANOTHER LOW AND TRAILING COLD FRONT WILL TRACK ACROSS THE AREA ON
THURSDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
BACK EDGE OF SNOW IS EAST OF ROUTE 23 AND EXITING THE REGION TO
THE EAST. WILL LET THE ADVISORY EXPIRE AT 10 ALTHOUGH I CONSIDERED
STRIPPING OUT THE WEST COUNTIES AND KEEPING THE EASTERN TIER IN.
INSTEAD OF MAKING THE FORECAST COMPLICATED FOR ANOTHER HALF
HOUR...DECIDED TO LET THE ADVISORY CONTINUE AND BY OR SHORTLY
AFTER IT EXPIRES AT 10 THE SNOW WILL HAVE ENDED OVER CWA.

TEMPERATURES WERE RUNNING ON AND WITH THE UNCERTAINTY IN CLOUD
COVER...LEFT THAT ALONE FOR THIS UPDATE PACKAGE. WILL LOOK HARDER
AT THIS IN A LITTLE BIT...ALTHOUGH EVEN WITH FULL SUN I DO NOT SEE
MUCH CHANCE OF WARMING TODAY AND HIGH TEMPERATURES SHOULD NOT SEE
ANY BIG CHANGES TODAY.

TEMPERATURES WILL STILL FALL SOME INTO THE DAYLIGHT HOURS ACROSS
THE SOUTHEAST. ONLY A MODEST REBOUND IN READINGS AT BEST FOR THE
ENTIRE AREA. FORECAST HIGHS ENDED UP BETWEEN MOS GUIDANCE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
HIGH PRESSURE WILL START NOSING INTO THE REGION TONIGHT. SHEARED
SHORT WAVE AND ITS WEAK SURFACE REFLECTION HAVE CONTINUED TO TREND
FURTHER WEST FOR TONIGHT INTO TUESDAY. SO DO NOT EXPECT THAT TO
BRING ANY PRECIPITATION TO THE FORECAST AREA. ONCE THAT WEAK
DISTURBANCE PASSES BY...HIGH PRESSURE WILL BE ABLE TO BUILD ACROSS
THE AREA TUESDAY NIGHT INTO WEDNESDAY. TEMPERATURES WILL BE BELOW
NORMAL WITH MOS LOOKING REASONABLE FOR LOWS AND HIGHS THROUGH THE
PERIOD.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
LOW PRESSURE AND ASSOCIATED COLD FRONT WILL APPROACH THE REGION
WEDNESDAY NIGHT AND MOVE ACROSS THURSDAY INTO THURSDAY EVENING.
00Z GUIDANCE ONLY INDICATING MINOR DIFFERENCES AT THIS POINT. AS
PRECIPITATION SPREADS INTO THE AREA LATE WEDNESDAY NIGHT IT
APPEARS THAT MUCH OF THE AREA WILL BE COLD ENOUGH FOR SNOW.
HOWEVER AS WARMER AIR ADVECTS IN...THIS WILL CHANGE TO RAIN
HEADING INTO THURSDAY WITH THE POTENTIAL FOR A BRIEF PERIOD OF
FREEZING RAIN WHERE THE ATMOSPHERE WARMS A BIT FASTER ALOFT THAN
AT THE SURFACE. THERE WILL BE A CHANGE BACK TO SNOW BEFORE
PRECIPITATION ENDS THURSDAY NIGHT AS COLD AIR GETS DRAWN IN AGAIN
ON THE BACK SIDE OF THE SYSTEM.

HIGH PRESSURE WILL BUILD IN FOR FRIDAY AND MOVE OFF TO THE EAST BY
EARLY SATURDAY. 00Z MODELS NOT IN AGREEMENT WITH THE NEXT SYSTEM.
THUS HAVE OPTED TO USE THE ENSEMBLE MEAN WHICH WOULD BRING A LOW
ACROSS THE AREA ON SUNDAY. THIS WOULD RESULT IN A CHANCE OF SNOW
FOR THE WEEKEND. BUT CLEARLY CONFIDENCE IS STILL LOW AT THIS
POINT.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
PRONOUNCED DRY PUNCH IN THE LOWER LEVELS IS DIGGING INTO WESTERN
OHIO THIS AFTERNOON AND WILL LIKELY KEEP LOWER MVFR CLOUD DECK OUT
OF WESTERN TAF SITES. THERE APPEARS TO BE A SLIGHT WESTWARD
BACKBUILDING IN NORTH CENTRAL OHIO THAT WILL KEEP THE LOW STRATUS
DECK OVER CENTRAL OHIO WITH A BRIEF BREAK EXPECTED LATER THIS
AFTERNOON AND EARLY EVENING. STRATUS WILL BUILD BACK IN OVERNIGHT
IN CENTRAL OHIO BUT THE NORTHERLY FLOW ORIGINATING FROM MICHIGAN
SHOULD KEEP WESTERN TAF SITES AWAY FROM LOW STRATUS CIGS TONIGHT.

UPPER LEVEL CLOUD COVER WILL STREAM OVER THE REGION ON NORTH-
NORTHWEST WINDS...BUT A BREAK SHOULD BE IN THE OFFING AT THE END
OF THE VALID TAF PERIOD AS THE STACKED LOW OVER THE EAST COAST
WRAPS AROUND SOME DRIER AIR IN THE OHIO VALLEY FROM THE UPPER
LEVELS OF THE ATMOSPHERE.

VSBYS SHOULD BE VFR THROUGH THE PERIOD.

OUTLOOK...MVFR CIGS AND VSBYS POSSIBLE THURSDAY.

&&
