NOT A WHOLE LOT OF CHANGES MADE THIS FORECAST PERIOD OTHER THAN
UPGRADING THE WINTER STORM WATCH TO A WINTER STORM WARNING FOR
MOST OF THE CWA THE ONLY EXCEPTION WAS FOR THE ISSUANCE OF A
WINTER WEATHER ADVISORY FOR ALLEN COUNTY IN OHIO. STILL LOOKING
LIKE SNOWFALL RANGING IN THE 4 TO 12 INCHES WITH LOCALLY HEAVIER
AMOUNTS ESPECIALLY IN AREAS THAT WILL GET LAKE ENHANCEMENT
BEGINNING SUNDAY. THE SMALLER ACCUMULATIONS WILL BE GENERALLY IN
THE SOUTHEASTERN PORTIONS OF THE CWA, SOUTH AND EAST OF
INTERSTATE 69 DUE TO THE WARM NOSE INTRODUCING SOME RAIN/SNOW
MIX ON LATE SATURDAY NIGHT INTO SUNDAY MORNING. SNOW WILL TEND
TO BE THE WETTER AND HEAVIER VARIETY ESPECIALLY FOR THE
SOUTHEASTERN PARTS OF THE FORECAST AREA. THERE ALSO WILL BE SOME
BUST POTENTIAL IF THE TRACK OF THE STORM SLIGHTLY DEVIATES OR
WARMER THAN EXPECTED LAYER DEVELOPS WITHIN THE ISENTROPIC
UPGLIDE ON THE EASTERN SIDE OF THE STORM. WINDS GUSTS OF 25 TO
30 MPH WILL BE EXPECTED WITH THIS STORM. WITH THE WETTER
SNOWFALL WOULD NOT EXPECT MUCH BLOWING SNOW ISSUES, HOWEVER ON
SUNDAY WITH THE DRIER SNOW WITH THE COLDER AIR BEING ENTRAINED
THERE MAY BE SOME BLOWING AND DRIFTING ACROSS AREA ROADS. ALSO,
WITHIN THE HEAVIER BANDS OF SNOWFALL VISIBILITIES WILL BE
GREATLY REDUCED AT TIMES. THE WETTER SNOW WILL ALSO MAKE
REMOVING THE SNOW MORE DIFFICULT AND PERHAPS HAZARDOUS. HEART
ATTACK SNOW COMES TO MIND.
ON SUNDAY EVENING AFTER THE STORM SHIFTS EASTWARD THERE IS A
CONCERN FOR SOME FLASH FREEZING WITH MUCH COLDER AIR SPILLING IN
BEHIND THIS SYSTEM. ANY WET ROADS AND ANY SNOWFALL LEFT ON THE
ROADS WILL LIKELY FREEZE UP ESPECIALLY ON UNTREATED SURFACES AND
RURAL ROADS WHICH ARE LIKELY TO MAKE FOR CONTINUED HAZARDOUS
ROAD CONDITIONS.
NEXT WEEK THE ARCTIC AIRMASS WILL BRING VERY COLD TEMPERATURES
ACROSS THE ENTIRE AREA WITH HIGHS ONLY IN THE 20S AND MOSTLY
TEENS FOR LOWS. FRIDAY MORNING LOOKS TO BE THE COLDEST WITH
SINGLE DIGITS FOR LOWS.
