000 FXUS63 KJKL 151901 AFDJKL AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 301 PM EDT TUE APR 15 2014 .SHORT TERM...
-- Changed Discussion --
(THIS EVENING THROUGH WEDNESDAY NIGHT) ISSUED AT 301 PM EDT TUE APR 15 2014 TWO SIGNIFICANT FORECAST ISSUES TO DEAL WITH IN THE SHORT TERM. FIRST WILL BE THE FRIGID TEMPERATURES WE ARE EXPECTING TONIGHT INTO EARLY TOMORROW MORNING AS A LATE SEASON ARCTIC AIR MASS SETTLES OVER THE AREA. THE LATEST MOS GUIDANCE CAME IN WITH OVERNIGHT LOWS RANGING IN THE LOW TO MID 20S FOR MOST LOCATIONS. WITH CLEAR AND NEARLY CALM CONDITIONS EXPECTED OVERNIGHT...THIS SEEMS LIKE A VERY REASONABLE SCENARIO. IN FACT...THE EXISTING TEMPERATURES IN THE FORECAST GRIDS FOR TONIGHT LOOKED VERY GOOD. A FEW MINOR TWEAKS WERE MADE HERE AND THERE FRO TONIGHTS LOWS...BUT OVERALL WE ARE STILL ANTICIPATING TEMPERATURES EASILY DROPPING INTO THE LOW TO MID 20S FOR MOST FOLKS...WITH SOME OF OUR COLDER VALLEYS PLUMMETING INTO THE TEENS. THE OTHER ISSUE OF NOTE WILL BE THE POTENTIAL FOR WIDESPREAD FROST AND A HARD FREEZE. THE NEW FORECAST WILL CONTINUE TO REFLECT THIS AND OUR FREEZE WARNING HAS ALREADY BEEN UPDATED AND IS GOOD UNTIL 10 PM THIS EVENING. IT LOOKS HIGHLY LIKELY THAT EASTERN KENTUCKY WILL EXPERIENCE A WIDESPREAD KILLING FREEZE EVENT TONIGHT INTO EARLY TOMORROW MORNING. COLD TEMPERATURES ARE ON TAP AGAIN WEDNESDAY NIGHT...BUT THINGS WILL NOT BE NEARLY AS COLD AS WE WILL SEE TONIGHT. AREAS OF FROST WILL ONCE AGAIN BE POSSIBLE AND THE SITUATION WILL BEAR WATCHING TO DETERMINE WHETHER OR NOT ANOTHER FREEZE PRODUCT WILL NEED TO BE ISSUED FOR THE WEDNESDAY NIGHT THURSDAY MORNING TIME FRAME. TEMPERATURES SHOULD REBOUND NICELY DURING THE DAY ON WEDNESDAY...WITH HIGHS CLIMBING INTO THE MID TO UPPER 50S ACROSS THE BOARD. MOSTLY CLEAR SKIES AND LIGHT WINDS WILL ON TAP THROUGHOUT THE PERIOD. .LONG TERM...(THURSDAY THROUGH TUESDAY) ISSUED AT 300 PM EDT TUE APR 15 2014 AN EXTENDED DISCUSSION WILL BE ISSUED SHORTLY.
