Clark Special Weather Statement in effect WINTRY WEATHER EXPECTED FOR THE LATTER HALF OF THE WEEK AND NEXT SUNDAY AN EXPANSIVE STORM SYSTEM WILL SPREAD FROM THE SOUTHERN PLAINS THROUGH THE OHIO VALLEY AND INTO NEW ENGLAND LATE THIS WEEK. ACROSS THE OHIO VALLEY AN ARCTIC COLD FRONT WILL SLIDE THROUGH THURSDAY EVENING WITH COLD AIR GRADUALLY WORKING IN BEHIND IT THURSDAY NIGHT THROUGH FRIDAY NIGHT. HOWEVER A LAYER OF WARM AIR ALOFT WILL REMAIN IN PLACE JUST ABOVE THE LOWER-LEVEL COLD AIR. THIS WILL BRING PRECIPITATION TYPES INTO QUESTION EARLY FRIDAY THROUGH FRIDAY NIGHT. CURRENT DATA SUGGESTS RAIN WILL BEGIN TRANSITIONING TO A MIX OF WINTRY PRECIPITATION ACROSS PORTIONS OF SOUTHERN INDIANA AS EARLY AS MIDNIGHT THURSDAY NIGHT. BY DAYBREAK FRIDAY THIS TRANSITION LINE OF RAIN TO A WINTRY MIX IS EXPECTED TO BE STRETCHED ALONG THE OHIO RIVER AND THEN MOVE SOUTH OF THE RIVER THROUGH THE DAY FRIDAY. BY FRIDAY EVENING COLD AIR AT ALL LEVELS WILL OVERSPREAD MOST OF THE AREA CHANGING MUCH OF THE PRECIPITATION OVER TO LIGHT SNOW AS THE EVENT ENDS FRIDAY NIGHT. THE LAKE CUMBERLAND REGION WILL LIKELY EXPERIENCE A WINTRY MIX AS THE EVENT COMES TO AN END. THE OVERALL PRECIPITATION TYPE EVOLUTION AND EXACT TIMING ARE NOT YET FULLY KNOWN AT THIS TIME. HOWEVER CONFIDENCE OF AN IMPACTFUL WINTRY WEATHER SCENARIO INCLUDING ACCUMULATIONS OF SNOW SLEET AND POSSIBLY SOME LIGHT FREEZING RAIN IS MODERATE NORTH OF THE OHIO RIVER AND LOW ALONG AND JUST SOUTH OF THE RIVER. STAY UP TO DATE WITH THE LATEST FORECASTS AS DETAILS BECOME MORE CLEAR ANOTHER WEATHER SYSTEM WILL IMPACT SOUTH-CENTRAL INDIANA AND CENTRAL KENTUCKY LATE SATURDAY NIGHT AND SUNDAY. COLD AIR WILL BE IN PLACE AT THE SURFACE EARLY SUNDAY WHICH SHOULD RESULT IN A PERIOD OF FREEZING RAIN ESPECIALLY OVER SOUTHERN INDIANA AS WELL AS NORTH-CENTRAL AND EAST-CENTRAL KENTUCKY WHERE A COATING OF ICE IS POSSIBLE. OVER SOUTH-CENTRAL KENTUCKY ANY FREEZING RAIN EARLY SUNDAY MORNING WILL CHANGE TO RAIN DURING THE DAY. THE FOCUS ON WINTRY WEATHER POTENTIAL SHOULD NOT TAKE AWAY FROM THE FACT THAT A HEAVY RAINFALL EVENT FROM THURSDAY THROUGH FRIDAY NIGHT AND AGAIN ON SUNDAY COULD LEAD TO SOME FLOODING CONCERNS. THIS IS ESPECIALLY TRUE ACROSS SOUTH-CENTRAL KENTUCKY WHERE 2 TO 4 INCHES OF RAIN ARE EXPECTED THROUGHOUT THE EVENT. IF YOU LIVE IN LOW LYING OR FLOOD PRONE AREAS WATCH WATER LEVELS CLOSELY IF HEAVY RAINS PERSIST AND TAKE NECESSARY PRECAUTIONS.
