STORM SYSTEM CONTINUES TO IMPACT THE SE HALF OF THE FA THIS MORNING. CANCELLED NW TIER OF COUNTIES OF HEADLINES AS ANY ADDITIONAL SNOWFALL IS EXPECTED TO BE LIGHT. WILL HIGHLIGHT THIS SNOW WITH A SPECIAL WEATHER STATEMENT. ADDITIONAL BANDS OF SNOW HAVE DEVELOPED PRIMARILY JUST SE OF INTERSTATE 71. DUE TO THIS HAVE KEPT MOST OF THE WINTER STORM WARNING IN PLACE. DID CANCEL RIPLEY AND DEARBORN COUNTIES FROM THE WINTER STORM WARNING SINCE THEY HAD RECEIVED LESS SNOWFALL AT THIS POINT FROM THE EVENT AND THEY ARE ON THE EDGE OF THE SNOW THIS MORNING. THERE IS A SHARP GRADIENT IN THE EXPECTED STORM TOTAL SNOWFALL VALUES FROM THIS EVENT. THE HIGHEST TOTALS STILL ARE EXPECTED TO BE ACROSS EXTREME SE PORTIONS OF THE FA WHERE LOCALLY A FOOT OR MORE OF SNOW TOTAL WILL BE POSSIBLE. SOME LOCATIONS HAVE ALREADY SEEN CLOSE TO A FOOT OF SNOW FROM LEWIS INTO SCIOTO COUNTIES. ON THE NW TIER OF THE CURRENT WINTER STORM WARNING...VALUES WILL BE SIGNIFICANTLY LESS AROUND 3 TO 6 INCHES. SNOW WILL CONTINUE FOR SEVERAL MORE HOURS THIS MORNING ACROSS MANY LOCATIONS SE OF INTERSTATE 71 ESPECIALLY EXTREME SE PORTIONS OF THE FA. SNOW WILL TAPER OFF BY AROUND THE MIDDLE OF THE DAY. AN INCH OF SNOW AN HOUR CAN BE EXPECTED WITH SOME OF THESE BANDS THIS MORNING. TEMPERATURES WILL STRUGGLE TO RISE TODAY WITH PLENTY OF CLOUD COVER AND COOL AIRMASS IN PLACE.

SOUTHERLY FLOW DEVELOPS ON FRIDAY AND THEREFORE TEMPERATURES WILL BE ABLE TO REBOUND INTO THE 20S FOR HIGH TEMPERATURES. TEMPERATURES WILL NOT DROP TOO MUCH FRIDAY NIGHT WITH AN INCREASE IN CLOUD COVER ACROSS THE FA. HAVE LOW TEMPERATURES DROPPING INTO THE TEENS EARLY AND THEN INCREASING A FEW DEGREES THROUGH THE NIGHT AS CLOUDS INCREASE. WARMER AIR WORKS INTO THE REGION FOR SATURDAY ALLOWING FOR HIGH TEMPERATURES IN THE 30S TO AROUND 40. HIGH PRESSURE WILL BEGIN TO WORK INTO THE AREA TONIGHT AND REMAIN ACROSS THE AREA FOR FRIDAY. THIS WILL ALLOW FOR DRY CONDITIONS THROUGH THIS TIME. A WEAK DISTURBANCE WILL WORK THROUGH THE AREA LATE FRIDAY NIGHT INTO SATURDAY.
