AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
310 PM EDT SUN MAY 12 2013

.SHORT TERM...-- Changed Discussion --
(TONIGHT AND MONDAY)...PATCHY FROST IS POSSIBLE
TONIGHT AS OVERNIGHT MINS WILL APPROACH THE LOWER TO MID 30S ACROSS
THE MAJORITY OF OUR CWA. THE BIG QUESTION IS STILL THE WINDS. WINDS
MAY BE RELUCTANT TO DROP OFF COMPLETELY WHICH MAY PROHIBIT
WIDESPREAD FROST DEVELOPMENT. IF THE WINDS DO NOT COMPLETELY
SUBSIDE...THEN FROST WILL LIKELY BE MORE LOCALIZED TO SHELTERED
AREAS THAT ARE PROTECTED FROM WINDS. SOUNDINGS INDICATE ELEVATIONS
ABOVE 4500 FEET WILL SEE NEAR FREEZING TEMPS WHILE AREAS AROUND
5000 FEET WILL APPROACH THE UPPER 20S. MINS TONIGHT WILL BE CHILLY
ENOUGH TO BE CLOSE TO RECORD LOWS FOR MAY 13TH.

A PLEASANT DAY IS IN STORE FOR MONDAY. HIGHER PRESSURE WILL BEGIN TO
BUILD IN AS THE DEEP LONG-WAVE TROUGH PUSHES FURTHER EAST.
HOWEVER...TEMPS ARE STILL EXPECTED TO BE ROUGHLY 10 DEGREES BELOW
NORMAL FOR THIS TIME OF YEAR.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)...COLD UPPER TROUGH
SHIFTS EAST TO OFF THE EAST COAST BY TUESDAY. ONE MORE COLD NIGHT
MONDAY NIGHT WITH LOWS MID TO UPPER 30S SHELTERED HIGHER VALLEYS IN
THE MOUNTAINS AND NE TN AND SW VA. COULD BE A LITTLE MORE FROST
EARLY TUESDAY THEN MUCH WARMER TEMPERATURES AS RIDGING ALOFT OVER
THE WESTERN STATES SHIFTS EAST INTO THE FORECAST AREA. A WEAK WARM
FRONT PASSES THROUGH TUESDAY WHICH MAY PRODUCE SOME LOW AND MOSTLY
MID LEVEL CLOUDINESS BUT NO SIGNIFICANT RAINFALL. EVEN WARMER
TEMPERATURES WEDNESDAY IN THE MID 80S AND CONTINUED DRY CONDITIONS.
HIGH PRESSURE AREA CENTER SHIFTS EAST AND SOUTHEAST TO THE EASTERN
GULF COAST WITH A GOOD SOUTHERLY FLOW OF MOISTURE. DEWPOINTS WILL
RISE AND THERE WILL BE A CHANCE OF MAINLY DIURNAL SHOWERS AND
THUNDERSTORMS FROM THURSDAY THROUGH THE WEEKEND.-- End Changed Discussion --
