ARCTIC HIGH PRESSURE WILL SLOWLY BUILD IN TODAY AND CROSS THE AREA TONIGHT. A WARM FRONT WILL LIFT INTO THE REGION SUNDAY AFTERNOON AND NIGHT. LOW PRESSURE WILL PASS SOUTHEAST OF THE AREA ON MONDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... HAVE LET THE WIND CHILL ADVISORY EXPIRE THIS MORNING. LOWERED CLOUD COVER SIGNIFICANTLY THOUGH IT SHOULD CU UP A LITTLE BIT MORE THIS AFTERNOON...PARTICULARLY IN THE NORTH. PREV AFD BELOW - IT APPEARS THAT FETCH WILL STABILIZE WITH ANOTHER BAND OF MOISTURE BECOMING ESTABLISHED ACROSS FAR NORTHERN COUNTIES THIS AFTERNOON. SO MORE SNOW SHOWERS/FLURRIES WILL BE POSSIBLE IN THOSE AREAS. OTHERWISE WILL SEE VARIABLE CLOUDINESS WITH CLEARING PUSHING IN FROM THE WEST IN THE AFTERNOON. TEMPERATURES WILL STRUGGLE TO RISE MUCH TODAY WITH HIGHS ONLY IN THE TEENS. && .SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/... SOME FLURRIES MAY STILL BE LINGERING IN PARTS OF CENTRAL OHIO AT THE BEGINNING OF THE PERIOD. BUT THEY WILL COME TO AN END AS THE CENTER OF THE HIGH MOVES ACROSS THE AREA. THIS WILL ALSO PROVIDE GOOD RADIATIONAL COOLING CONDITIONS WITH ONLY SOME HIGH CLOUDS STARTING TO ADVANCE AHEAD OF THE NEXT SYSTEM. HAVE CONTINUED TO UNDERCUT GUIDANCE LOWS. SHORT WAVE WILL TRACK FROM THE UPPER MISSISSIPPI VALLEY INTO THE GREAT LAKES SUNDAY INTO SUNDAY NIGHT. AS THIS OCCURS A WARM FRONT AT THE SURFACE WILL APPROACH SUNDAY AFTERNOON AND LIFT THROUGH THE AREA SUNDAY NIGHT. AS A RESULT OF THESE TWO SOURCES OF LIFT WIDESPREAD LIGHT PRECIPITATION WILL BREAK OUT. THIS WILL BE IN THE FORM OF SNOW WITH ACCUMULATIONS FROM 1 TO 3 INCHES. FORECAST BECOMES MORE COMPLICATED BEYOND THIS TIME FRAME. NEXT SHORT WAVE WILL TRACK FROM THE MID SOUTH INTO THE APPALACHIANS MONDAY INTO MONDAY NIGHT. ASSOCIATED SURFACE LOW WILL PASS WELL SOUTH AND EAST OF THE REGION. 00Z GUIDANCE CONTINUES TRENDS OF THIS BEING PROGRESSIVE AND LESS AMPLIFIED. BUT DIFFERENCES REMAIN CONCERNING HOW FAR NORTH OF THE LOW THE SHIELD OF PRECIPITATION DEVELOPS...WHETHER THERE WILL BE A BREAK AFTER THE WARM FRONTAL PRECIPITATION...AND HOW MUCH WARMING THERE WILL BE WHICH MAY AFFECT PRECIPITATION TYPE. GIVEN UNCERTAINTY HAVE USED A BLEND THAT SHOULD BE MIDDLE OF THE ROAD WITHIN THE ENVELOPE OF MODEL SOLUTIONS. SO ADDITIONAL LIGHT ACCUMULATIONS WILL BE POSSIBLE DURING THIS TIME PERIOD ALTHOUGH THAT COULD BE MINIMAL IF PRECIPITATION MIXES WITH OR CHANGES TO RAIN. TEMPERATURES WILL REMAIN BELOW NORMAL SUNDAY BUT THERE WILL BE LITTLE IF ANY DROP EARLY SUNDAY EVENING BEFORE READINGS RISE THROUGH THE REMAINDER OF THE NIGHT.

BUT THEN ANOTHER SHORT WAVE WILL MOVE INTO THE AREA FRIDAY BRINGING RAIN SHOWERS AHEAD OF A COLD FRONT. TEMPERATURES WILL REMAIN COOL DURING MID WEEK AND THEN RISE ABOVE NORMAL BY THE END OF THE PERIOD. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... CU FIELD IS THICKENING OVER THE REGION THIS AFTERNOON BUT WILL REMAIN VFR EVEN IF A BKN DECK PRESENTS ITSELF. WINDS SHIFTING WEST WILL PUSH RELATIVELY WARMER AIR INTO THE OHVLY AND ERODE THE WESTERN EDGE OF THE CU THIS AFTERNOON. BY THE LATE DAY...THE REST OF THE REGION WILL SEE ANY CU DISSIPATE BY NIGHTFALL WITH THE EXCEPTION OF CENTRAL OHIO WHERE KCMH/KLCK MAY HANG ON TO A VFR DECK THROUGH ABOUT 2Z. HIGH CLOUDS WILL STREAM IN OVERNIGHT AS THE SURFACE HIGH MAKES WINDS LIGHT AND VARIABLE AND EVENTUALLY TURN THEM SOUTHEAST BY MORNING.
