AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
700 PM EST SUN FEB 15 2015
.SYNOPSIS...
HIGH PRESSURE WILL ALLOW FOR DRY CONDITIONS ACROSS THE AREA THIS
EVENING AND MOST OF TONIGHT. AN AREA OF LOW PRESSURE WILL MOVE
SOUTH OF THE REGION MONDAY INTO MONDAY NIGHT BRINGING ACCUMULATING SNOW
TO THE AREA. A DISTURBANCE WILL WORK THROUGH THE REGION TUESDAY
INTO TUESDAY NIGHT BRINGING THE CHANCE FOR SOME SNOW SHOWERS AND
COLDER TEMPERATURES TO THE REGION.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
DRY CONDITIONS WILL CONTINUE ACROSS THE AREA THIS EVENING WITH
HIGH PRESSURE IN PLACE. ALTHOUGH SOME WIND CHILL VALUES WILL REACH
WIND CHILL ADVISORY CRITERIA TONIGHT ACROSS THE NORTH...WINDS WILL
BE LESS THAN REQUIRED FOR A WIND CHILL ADVISORY AND THEREFORE HAVE
DECIDED AGAINST A WIND CHILL ADVISORY FOR TONIGHT. TEMPERATURES
WILL DROP ACROSS THE AREA FOR THE FIRST HALF OF THE NIGHT HOWEVER
EXPECT TEMPERATURES TO INCREASE SOME OVERNIGHT AS CLOUD COVER
INCREASES. PRECIPITATION WILL HOLD OFF FOR MOST OF THE NIGHT. SNOW
WILL BEGIN TO MOVE INTO SW PORTIONS OF THE FA BY THE END OF THE
NEAR TERM.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/...
SNOW WILL OVERSPREAD THE AREA ON MONDAY. HIGH TEMPERATURES ON
MONDAY ARE ONLY EXPECTED TO BE IN THE TEENS. DUE TO THIS THERE
WILL BE HIGH SNOW RATIOS FOR THIS SYSTEM. MODELS HAVE COME INTO
MUCH BETTER AGREEMENT WITH THIS SYSTEM HOWEVER THERE ARE STILL
SOME MINOR DIFFERENCES IN STRENGTH AND NORTHWARD EXTENT OF THIS
SYSTEM.
THE HEAVIEST SNOW WITH THIS SYSTEM IS EXPECTED TO BE ALONG AND
SOUTH OF THE OHIO RIVER WITH SNOWFALL TOTALS DECREASING FURTHER TO
THE NORTH. AROUND 6 TO 10 INCHES ARE EXPECTED ALONG AND SOUTH OF
THE OHIO RIVER. NORTH OF INTERSTATE 70 LESS THAN AN INCH OF SNOW
IS EXPECTED. IN BETWEEN THERE WILL BE A TIGHT GRADIENT IN SNOWFALL
VALUES. A SHARP CUT OFF IN THE NORTHERN EXTENT OF THE SNOWFALL IS
EXPECTED AND A SHARP GRADIENT IN SNOWFALL VALUES IS EXPECTED.
WENT WITH A WINTER STORM WARNING FROM FRANKLIN COUNTY INDIANA
EASTWARD TO HOCKING COUNTY OHIO. THESE LOCATIONS ARE IN THE 4 INCH
WINTER STORM WARNING CRITERIA. DUE TO THE RECENT NORTHWARD TREND
DECIDED TO HAVE A ROW OF COUNTIES NORTH OF THIS IN A WINTER
WEATHER ADVISORY. MORE CONFIDENT IN THE WINTER WEATHER ADVISORY
FROM FAYETTE COUNTY OHIO TO FAIRFIELD COUNTY OHIO WHERE WINTER
WEATHER CRITERIA IS 2 INCHES. THERE IS LESSER CONFIDENCE IN THE
ADVISORY FROM FAYETTE COUNTY INDIANA EASTWARD TO GREENE COUNTY
OHIO WHERE THE ADVISORY CRITERIA IS 3 INCHES. AS MENTIONED HOWEVER
WITH THE NORTHWARD SHIFT AND VALUES NEAR CRITERIA DECIDED TO GO
WITH AN ADVISORY ACROSS THESE COUNTIES.
SNOW WILL MOVE OUT OF THE AREA MONDAY NIGHT. THERE WILL BE A BRIEF
LULL BEFORE ANOTHER SYSTEM MOVES THROUGH TUESDAY AFTERNOON INTO
TUESDAY NIGHT. THIS SYSTEM WILL BRING LIGHT SNOW SHOWER ACTIVITY
TO THE AREA AND COLDER AIR TO THE REGION. WIND CHILL VALUES WILL
DROP BELOW ZERO TUESDAY NIGHT. MANY LOCATIONS ARE EXPECTED TO HAVE
WIND CHILL VALUES LOWER THAN NEGATIVE TEN AND THEREFORE FUTURE
FORECASTS WILL HAVE TO BE MONITORED FOR POTENTIAL WIND CHILL
ADVISORIES.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
ARCTIC AIR WILL WILL BE PERSISTENT FOR THE LATTER HALF OF THE WEEK.
WITH SNOW COVER EXPECTED ACROSS MOST IF NOT ALL OF THE AREA...
TEMPERATURES WILL BE APPROACHING RECORD COLD...BOTH FOR MAXES AND
MINS. CANNOT RULE OUT SOME SNOW SHOWERS ON WEDNESDAY WITH THE BETTER
POTENTIAL ACROSS FAR NORTHERN COUNTIES DOWNSTREAM OF THE FETCH OFF
LAKE MICHIGAN. AS LOW LEVEL FLOW BACKS FURTHER THE CHANCE OF
LINGERING SNOW SHOWERS WILL END. CENTER OF THE ARCTIC HIGH WILL PASS
ACROSS THE REGION THURSDAY NIGHT INTO FRIDAY. NEXT SYSTEM DEVELOPING
IN THE PLAINS WILL SPREAD MOISTURE INTO THE AREA ON SATURDAY.
TEMPERATURES WILL MODERATE SOMEWHAT ALTHOUGH STILL BE BELOW NORMAL.
A COLD FRONT WILL SLIDE THROUGH THE REGION SATURDAY NIGHT BUT MIGHT
NOT MAKE IT MUCH FURTHER SOUTH ON SUNDAY. CURRENTLY APPEARS THAT
THERE COULD BE AN EXTENDED CHANCE OF PRECIPITATION THROUGH THE
WEEKEND. TEMPERATURES SHOULD BE COLD ENOUGH FOR PRECIPITATION TYPE
TO BE SNOW ALTHOUGH THERE COULD BE A MIX WITH RAIN IN THE SOUTH.
&&
.AVIATION /00Z MONDAY THROUGH FRIDAY/...
MAINLY CLEAR SKIES ACROSS THE AREA EARLY THIS EVENING WILL GIVE WAY
TO INCREASING MID CLOUDS FROM THE WEST LATER THIS EVENING INTO THE
OVERNIGHT HOURS. AN INVERTED TROUGH WILL NOSE UP TOWARD OUR AREA
LATE TONIGHT AND THEN SHIFT EAST ACROSS THE REGION THROUGH THE DAY
ON MONDAY. AS DEEPER MOISTURE SPREADS IN LATE TONIGHT INTO MONDAY
MORNING...EXPECT SNOW TO DEVELOP FAIRLY QUICKLY WEST TO EAST
ACROSS SOUTHERN PORTIONS OF OUR AREA WITH CIGS/VSBYS DROPPING INTO
IFR AT KCVG/KLUK AND REMAINING THERE THROUGH MUCH OF THE DAY.
THERE WILL BE A SHARP NORTHERN CUT OFF WHICH WILL PUT THE I-70 TAF
SITES ON THE EDGE OF SNOW/NO SNOW. AS A RESULT...WILL LIMIT
KDAY/KCMH/KLCK TO MVFR CONDITIONS...BUT CIGS/VSBYS WILL ULTIMATELY
BE DEPENDENT ON EXACTLY WHERE THIS NORTHERN CUTOFF SETS UP.
SIGNIFICANT SNOW ACCUMULATIONS WILL LIKELY AFFECT GROUND
OPERATIONS AT KCVG/KLUK THROUGH THE DAY ON MONDAY.
