AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
327 AM EDT TUE APR 15 2014

.SHORT TERM...(TODAY THROUGH WEDNESDAY)
ISSUED AT 327 AM EDT TUE APR 15 2014

COLD FRONT NOW EXTENDS FROM JUST EAST OF HUNTINGTON...TO JUST EAST OF
JACKSON...TO NEAR MIDDLESBORO THIS MORNING. PERIODS OF LIGHT
RAIN/DRIZZLE CONTINUES ACROSS EASTERN KENTUCKY WITH THE CONVERGENCE
WITH THE PASSING FRONT. DEEP MOISTURE AND LIFT WILL REMAIN BEHIND THE
FRONT THROUGH THE MORNING HOURS...SUPPORTING PRECIPITATION THROUGH
LATE MORNING. AS WE HEAD TOWARDS MIDDAY AND ESPECIALLY INTO THE
AFTERNOON HOURS...PRECIPITATION WILL END FROM WEST TO EAST. STILL
LOOKS LIKE A GOOD POTENTIAL FOR SOME SNOW FOR MOST AREAS AROUND OR
SHORTLY AFTER DAYBREAK. WITH TEMPERATURES COOLING WELL UNDER FREEZING
IN THE HIGHER TERRAIN ABOVE 2000 FEET IN THE SOUTHEAST...THIS MAY
ALLOW FOR BETTER ACCUMULATION POTENTIAL FOR THESE AREAS. BASED ON
EXPECTED PRECIPITATION...IT LOOKS LIKE 1 TO 3 INCHES OF SNOW WILL BE
POSSIBLE ON THE HIGHER RIDGETOPS. WHILE LITTLE IMPACT IS
ANTICIPATED...SOME REDUCED VISIBILITIES COULD OCCUR. THUS...PLAN TO
ISSUE AN ELEVATION BASED WINTER WEATHER ADVISORY FOR THE COUNTIES
BORDERING VIRGINIA THIS MORNING.

COLD ADVECTION WILL CONTINUE INTO MIDDAY AS TEMPERATURES HOLD STEADY
OR CONTINUE TO FALL THROUGH THE 30S OR 20S FOR THE HIGHER ELEVATIONS.
CLOUDS WILL HOLD TOUGH THROUGH THE DAY GIVEN THE UPSLOPE
CONDITIONS...BUT DRY AIR SHOULD OVERWHELM THE CLOUDS LATE IN THE
DAY...WITH CLOUDS ON A GENERAL DECREASE THROUGH THE EVENING HOURS.
THIS WILL SET UP A RECORD COLD NIGHT WITH LOWS EXPECTED WELL INTO THE
20S AND THE COLDER VALLEYS FALLING INTO THE UPPER TEENS. THIS
WARRANTS THE CURRENT FREEZE WARNING. A BIG DIURNAL SWING IN
TEMPERATURES EXPECTED ON WEDNESDAY AS WE START OFF COLD...BUT SHOULD
RECOVER WELL INTO THE 50S OR LOWER 60S BY THE AFTERNOON. THIS BIG
DIURNAL CURVE WILL FEATURE SOME VERY LOW RELATIVE HUMIDITIES FOR THE
AFTERNOON HOURS ON WEDNESDAY. FORTUNATELY...WINDS WILL REMAIN VERY
LIGHT THROUGH THE DAY.

.LONG TERM...(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 327 AM EDT TUE APR 15 2014

LONG TERM DISCUSSION TO FOLLOW SHORTLY.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z TUESDAY NIGHT)
ISSUED AT 208 AM EDT TUE APR 15 2014

VFR CONDITIONS CONTINUE TO GIVE WAY TO LOWER MVFR/IFR CIGS. THIS
TREND WILL CONTINUE OVER THE NEXT FEW HOURS...WITH CIGS FALLING TO
BETWEEN 600 AND 800 FEET THROUGH THE REMAINDER OF THE NIGHT. THIS WILL
CIGS NEAR AIRPORT MINIMUMS. IN ADDITION...WINDS WILL CONTINUE TO SHIFT
AROUND TO THE WEST AND EVENTUALLY NORTHWEST. RAIN WILL MIX WITH AND
CHANGE TO SNOW IN SOME AREAS AROUND DAYBREAK...BEFORE ENDING BY EARLY
AFTERNOON. AS WE HEAD THROUGH THE DAY WE SHOULD EVENTUALLY GO BACK TO
MVFR AND VFR BY LATE AFTERNOON. HOWEVER...SOME QUESTION AS TO HOW
FAST THIS INCREASE TAKES PLACE.
