During the overnight of January 20th, arctic air moved through the Ohio Valley with a strengthening surface low crossing east through the Tennessee Valley. An upper level disturbance crossed the region at the same time, creating a narrow band of higher intensity snowfall over the region.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
737 PM EST MON JAN 20 2014
.SYNOPSIS...
A DISTURBANCE WILL LINK UP WITH AN APPROACHING ARCTIC AIRMASS TO
PRODUCE SNOW ACROSS THE AREA TONIGHT INTO TUESDAY MORNING. THE
ARCTIC AIRMASS WILL REMAIN IN PLACE INTO THE MIDDLE OF THE WEEK.
A WEAK DISTURBANCE WILL BRING SNOW TO THE REGION AGAIN ON
WEDNESDAY NIGHT.
&&
.NEAR TERM /THROUGH TUESDAY/...
AN UPPER LEVEL DISTURBANCE WILL DROP SOUTHEASTWARD FROM THE
NORTHERN PLAINS TONIGHT. AN ARCTIC AIRMASS IS POSITIONED NORTH OF
OUR REGION AT THIS TIME. AS THE DISTURBANCE MOVES INTO OUR REGION
THIS EVENING...A SURFACE LOW WILL BEGIN TO DEVELOP ACROSS THE
TENNESSEE VALLEY IN RESPONSE TO THE APPROACHING UPPER LEVEL
ENERGY. THE LOW WILL THEN INTENSIFY TONIGHT WHILE MOVING
EASTWARD...AS THE ARCTIC AIRMASS BEGINS TO MOVE INTO THE OHIO
VALLEY. PRECIPITATION WILL INTENSIFY IN THE FORM OF SNOW ON THE
NORTH SIDE OF THE LOW AS IT TRACKS SOUTH OF OUR AREA TONIGHT. THE
12Z MODEL RUNS CAME IN NOTABLY HIGHER IN THEIR QPF TOTALS WITH
THIS SYSTEM...WHICH COULD IN PART BE DUE TO THE INTENSIFYING
CHARACTERISTIC OF THE LOW AS IT PASSES BY OUR AREA. THIS HAS
RESULTED IN AN OVERALL UPTICK IN THE TOTAL SNOW ACCUMULATION FROM
THIS SYSTEM ACROSS OUR ZONES. HI-RES MODELS HAVE BEEN INDICATING
A CORRIDOR OF HIGHER SNOWFALL TOTALS...DUE TO THE DEVELOPMENT OF A
FRONTOGENETIC SNOW BAND NORTH OF THE LOW AS IT INTENSIFIES EARLY
TUESDAY MORNING. THE PROBLEMATIC PART OF INCLUDING THIS SNOW BAND
DETERMINISTICALLY INTO THE STORM TOTAL...IS THE FACT THAT IT IS TOO
EARLY TO KNOW WHERE THIS BAND WILL SETUP. THEREFORE...WITH WITH A
SMOOTHED MEAN OF THE SNOW BAND FORECAST LOCATION BY THE
MODELS...WHICH RESULTS IN A LARGE AREA OF 2 TO 4 INCHES OF
SNOWFALL FORECAST. THE SCENARIO THAT WILL MOST LIKELY PLAY OUT
WILL BE A WIDESPREAD 1 TO 3 INCH SNOWFALL ACCUMULATION WITH A BAND
OF HIGHER AMOUNTS APPROACHING...IF NOT EXCEEDING...4 INCHES WHERE
THE FRONTOGENETIC BAND SETS UP. REGARDLESS OF WHETHER SPECIFIC
LOCATIONS REACH WINTER WEATHER ADVISORY CRITERIA...WINDS BEHIND
THE LOW WILL INCREASE TONIGHT WHILE THE TIMING OF MOST INTENSE
SNOWFALL MAY OCCUR CLOSE TO SUNRISE AND THE MORNING COMMUTE. THIS
COULD PRODUCE LOW VISIBILITIES...SLICK ROADWAYS...WITH BLOWING
SNOW TUESDAY MORNING...RESULTING IN SIGNIFICANT TRAVEL IMPACTS. HAVE
THEREFORE ISSUED A WINTER WEATHER ADVISORY FOR LOCATIONS MAINLY
SOUTH OF THE INTERSTATE 70 CORRIDOR...WHERE THE HIGHEST LIKELY-
HOOD OF IMPACTS WILL OCCUR.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
THE LOW WILL CROSS THE APPALACHIANS TUESDAY MORNING WHILE HIGH
PRESSURE TO OUR WEST CONTINUES TO PUSH ARCTIC AIR INTO OUR REGION.
WIND AND SNOW WILL BE OCCURRING ACROSS MUCH OF THE AREA AT THE
START OF THE SHORT TERM...WITH SNOW ENDING FROM NORTHWEST TO
SOUTHEAST DURING THE MORNING HOURS. NORTHERLY WINDS OF 15 TO 20
MPH...GUSTING UP TO 30 MPH...WILL OCCUR THROUGHOUT THE DAY AS
TEMPERATURES STRUGGLE TO RISE OUT OF THE SINGLE DIGITS ACROSS THE
NORTH...AND TEENS ACROSS THE SOUTH. THESE WINDS COMBINED WITH THE
COLD TEMPERATURES WILL PRODUCE WIND CHILL VALUES NEAR OR BELOW
ZERO ALL DAY NORTH OF THE OHIO RIVER...AND IN THE SINGLE DIGITS TO
THE SOUTH.
AS TEMPERATURES CONTINUE TO DROP INTO THE OVERNIGHT HOURS TUESDAY
NIGHT...WINDS WILL GRADUALLY DIMINISH. HOWEVER...WINDS ARE
EXPECTED TO STILL BE SUFFICIENT...AROUND 5 TO 10 MPH...TO COMBINE
WITH TEMPERATURES AT OR BELOW ZERO NORTH OF THE OHIO RIVER...TO
PRODUCE WIND CHILLS THAT MAY DIP APPROACH OR DIP BELOW -10
DEGREES AT TIMES TUESDAY NIGHT THROUGH WEDNESDAY MORNING. WILL
CONTINUE TO HIGHLIGHT THE POTENTIAL FOR THESE DANGEROUSLY COLD WIND
CHILLS IN THE HWO.
HIGH PRESSURE WILL SLIDE ACROSS THE REGION WEDNESDAY MORNING AND
AN UPPER LEVEL TROUGH WILL BEGIN TO MOVE SOUTH FROM LAKE SUPERIOR
TOWARD OUR REGION. A WEAK SURFACE LOW WILL DEVELOP AHEAD OF THIS
TROUGH AND IS EXPECTED TO BRING A CHANCE OF SNOW TO OUR AREA BY
WEDNESDAY EVENING AND INTO THE OVERNIGHT HOURS. MODELS ARE
CURRENTLY SHOWING QPF UNDER A TENTH OF AN INCH WITH THIS SYSTEM AT
THIS TIME. AND...DUE TO THE UNCERTAIN NATURE OF THE EXACT TRACK OF
THIS FEATURE...WILL LIMIT POPS UNDER THE LIKELY CATEGORY FOR THE
TIME BEING.
TEMPERATURES WEDNESDAY WILL TOP OFF IN THE TEENS ACROSS THE NORTH
AND LOW 20S ACROSS THE SOUTH...WITH SINGLE DIGIT TEMPERATURES
FORECAST ACROSS THE NORTH WEDNESDAY NIGHT AND TEENS ACROSS THE
SOUTH. WINDS WILL COMBINE WITH THE COLDER TEMPERATURES TO PRODUCE
WIND CHILLS AT OR BELOW ZERO AT TIMES WEDNESDAY AND WEDNESDAY
NIGHT. WILL CONTINUE TO HIGHLIGHT THESE WIND CHILLS IN THE HWO.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
A LOW LEVEL TROUGH AXIS WILL PIVOT DOWN ACROSS THE AREA THROUGH THE
DAY ON THURSDAY IN THE WAKE OF A LOW PRESSURE WAVE PUSHING OFF TO
THE EAST. THIS WILL BE ACCOMPANIED BY DECENT CAA...LIMITING
TEMPERATURE RECOVERY THROUGH THE DAY. THE 12Z NAM/09Z SREF ARE BOTH
INDICATING THE POSSIBILITY OF SOME SCATTERED SNOW SHOWER DEVELOPMENT
THROUGH THE DAY AS THE LOW LEVEL LAPSE RATES INCREASE. MOISTURE
COULD BE A LIMITING FACTOR BUT WITH A FETCH OFF OF THE LAKES
POSSIBLE...WILL ALLOW FOR A 20-30 POP ON INTO THE AFTERNOON.
SURFACE HIGH PRESSURE WILL BUILD IN FROM THE SOUTHWEST THURSDAY
NIGHT. SKY CONDITIONS WILL BE DEPENDENT ON THE FLOW OFF OF THE
LAKES...BUT EXPECT AT LEAST SOME PARTIAL CLEARING ACROSS THE AREA.
IF THIS OCCURS...TEMPERATURES WILL LIKELY FALL BELOW ZERO ACROSS
MUCH IF NOT ALL OF OUR FA BY EARLY FRIDAY MORNING. INCREASING WEST
TO SOUTHWEST LOW LEVEL FLOW WILL HELP PUSH THE CORE OF THE COLD AIR
OFF TO THE EAST FRIDAY INTO FRIDAY NIGHT...MAKING FOR A DIFFICULT
TEMP FORECAST DEPENDING ON HOW FAST THE WAA DEVELOPS. WILL GENERALLY
GO WITH HIGHS IN THE UPPER TEENS NORTH TO LOWER LOWERS SOUTH FOR
FRIDAY.
THE UPPER LEVEL TOUGH WILL REESTABLISH ITSELF OVER THE EASTERN
UNITED STATES THROUGH THE WEEKEND AND ON INTO EARLY NEXT WEEK...WITH
SEVERAL REINFORCING SHOTS OF COLDER AIR PUSHING DOWN INTO OUR AREA.
THE ECMWF AND GFS CONTINUE TO DIFFER WITH BOTH THE TIMING AND
STRENGTH OF THE VARYING SHORT WAVES AND COLD AIR PUSHES. IT LOOKS
LIKE THE FIRST ONE WILL AFFECT OUR REGION SATURDAY INTO SATURDAY
NIGHT BUT DUE TO SOME OF THE UNCERTAINTIES...WILL KEEP POPS IN THE
CHANCE CATEGORY. TEMPERATURES WILL ALSO BE DEPENDENT ON THE EXACT
TIMING...BUT IT LOOKS LIKE THE COLD AIR MAY HOLD OF LONG ENOUGH TO
ALLOW FOR HIGHS ON SATURDAY TO RISE UP IN THE UPPER 20S TO POSSIBLY
LOWER 30S ACROSS OUR SOUTH...WITH COLDER AIR THEN PUSHING BACK IN
FOR SATURDAY NIGHT INTO SUNDAY. IN NORTHWEST FLOW ALOFT...IT WILL
REMAIN TOUGH TO RULE OUT THE POSSIBILITY OF A CLIPPER TYPE SYSTEM
DROPPING DOWN AND AFFECTING OUR REGION SUNDAY INTO MONDAY. THE 12Z
GFS IS SUGGESTING THE POSSIBILITY OF ONE FOR SUNDAY SO WILL MAINTAIN
SOME LOWER POPS ON THROUGH THE WEEKEND...BUT MODEL TIMING AND
PLACEMENT THIS FAR OUT WITH CLIPPERS IS HIGHLY UNRELIABLE.
&&
.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
CONDITIONS TO DETERIORATE LATE TONIGHT AS THE NEXT WEATHER SYSTEM
MOVES IN AND SNOW OVERSPREADS THE TAF SITES. A COLD FRONT ACRS SRN
GREAT LAKES TO PUSH SOUTH THRU THE TAF SITES LATE TONIGHT. MVFR
CIGS WILL DEVELOP IN THE WAKE OF THIS FRONT. A WAVE OF LOW
PRESSURE WILL DROP SE ALONG THE FRONT INTO KY OVERNIGHT WITH AN
ENHANCED BAND OF SNOW DEVELOPING NORTH OF THIS WAVE ACRS THE TAFS.
EXPECT A PERIOD OF ACCUMULATING SNOW...IFR CONDITIONS ARE PROBABLE
FROM AROUND 09Z TO 14Z. AS THE WAVE MOVES EAST EXPECT SOME
IMPROVEMENT TO MVFR BY TUESDAY AFTN AND VFR TUESDAY NIGHT.
NORTH WINDS WILL GUST UP TO 27 KTS LATE TONIGHT INTO TUESDAY AND
THEN BECOME NW AROUND 10 KTS TUESDAY NIGHT.
OUTLOOK...MVFR CONDITIONS POSSIBLE WEDNESDAY INTO THURSDAY.
