(TODAY THROUGH FRIDAY) ISSUED AT 514 AM EST THU MAR 5 2015 A MAJOR WINTER STORM CONTINUES TO AFFECT EASTERN KENTUCKY EARLY THIS MORNING. A LARGE AREA OF MODERATE SNOW IS CURRENTLY MOVING ACROSS PORTIONS OF EASTERN KENTUCKY GENERALLY EAST OF THE I75 CORRIDOR. ANOTHER BAND OF INTENSE SNOW IS ALSO REORGANIZING AND MOVING BACK INTO OUR FAR NORTHWESTERN COUNTIES. A QUICK CHECK OF UPSTREAM RADAR LOOPS CLEARLY SHOWS MORE BANDS AND AREAS OF MODERATE TO HEAVY SNOW MOVING INTO SOUTH CENTRAL KENTUCKY THAT WILL EVENTUALLY MAKE THEIR WAY INTO OUR AREA. EVEN THOUGH SNOW TOTALS ACROSS THE AREA HAVE NOT BEEN QUITE AS HIGH TO THIS POINT AS WE HAD PREVIOUSLY FORECAST...IT DOES APPEAR WE WILL HAVE PLENTY OF CHANCES THROUGHOUT THE MORNING TO PICK UP WARNING CRITERIA SNOW FALL FOR ALL OF THE AREA. THE ONE AREA WHERE THE SNOW HAS BEEN PILING UP QUICKLY IS NORTH OF THE MOUNTAIN PARKWAY. THE I64 CORRIDOR HAS SEEN A NUMBER OF LOCATIONS PICK UP 6 TO 8 INCHES OF SNOW SINCE YESTERDAY EVENING. AT THIS TIME IT APPEARS THAT MORE SNOW IS ON THE WAY...SO THERE COULD BE AREAS UP THERE THAT SEE AROUND A FOOT OF SNOW BEFORE THE EVENT COMES TO AND LATE THIS MORNING. THE FORECAST GRIDS WERE MODIFIED TO REFLECT THE HIGHER SNOW FALL AMOUNTS IN OUR FAR NORTH IN RELATION TO A NARROW BAND OF HEAVY SNOW THAT MOVED THROUGH THERE OVERNIGHT. THE NEW FORECAST WILL ALSO REFLECT HIGHER SNOW AMOUNTS IN THE CENTRAL AND EASTERN PORTIONS OF THE AREA PER THE LATEST HRRR MODEL OUTPUT. TEMPERATURES FOR TODAY WILL NOT RISE VERY MUCH DUE TO ALL THE SNOW...SO HIGHS WILL LIKELY ONLY TOP OUT 20S ACROSS THE AREA. THE SNOW SHOULD BEGIN WINDING DOWN BY MID MORNING...AND BE OUT OF EASTERN KENTUCKY BY MID AFTERNOON. FLOODING WILL ALSO CONTINUE TO BE AN ISSUE TODAY AND TOMORROW...AS AREA RIVERS HAVE BECOME SWOLLEN DUE TO HEAVY RAINFALL FROM THE PAST 24 HOURS AND RUNOFF FROM SNOW MELT. NUMEROUS FLOOD WARNINGS ARE CURRENTLY IN AFFECT ACROSS THE ENTIRE AREA. A NUMBER OF OUR RIVERS WILL CONTINUE TO RUN HIGH THROUGH THE DAY ON FRIDAY. .LONG TERM...(FRIDAY NIGHT THROUGH WEDNESDAY) ISSUED AT 514 AM EST THU MAR 5 2015 AN EXTENDED DISCUSSION WILL BE ISSUED SHORTLY.
