AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
251 PM CDT MON JUN 30 2014

.DISCUSSION...

SHOWERS AND STORMS ARE CONFINED TO THE EASTERN PART OF THE CWA
THIS AFTERNOON WHERE MID-LEVEL TEMPS ARE QUITE A BIT COOLER ON THE
PERIPHERY OF A RIDGE AXIS. HAVE KEPT DRY CONDITIONS IN FOR TUESDAY
AS THE INFLUENCE OF THE RIDGE SPREADS EASTWARD ACROSS THE FORECAST
AREA. A SIMILAR STORY IS EXPECTED FOR WEDNESDAY...BUT A TROUGH
TO OUR NORTHWEST COULD WEAKEN THE RIDGE ENOUGH TO ALLOW FOR A FEW
SHOWERS AND STORMS WEDNESDAY AFTERNOON ACROSS THE NORTHWEST.
TEMPERATURE GUIDANCE CONTINUES TO INSIST ON HIGH TEMPERATURES
REACHING 100F ON TUESDAY AND WEDNESDAY ACROSS THE SOUTH...BUT THIS
SEEMS TOO HIGH GIVEN THE WARM BIAS OF GUIDANCE SO FAR THIS SUMMER
AND MODEST 500MB HEIGHTS AT 5900M.

THE AFOREMENTIONED TROUGH AXIS WILL MOVE INTO THE REGION ON
WEDNESDAY NIGHT INTO THURSDAY IN ASSOCIATION WITH A SURFACE COLD
FRONT. DEEP-LAYER MOISTURE APPEARS SOMEWHAT LIMITED WITH
NORTHWEST WINDS ALOFT...BUT HAVE INCLUDED SMALL RAIN CHANCES FOR
THE SOUTHERN AREAS ON THURSDAY. COOLER AND DRIER AIR SHOULD
OVERSPREAD THE FORECAST AREA THURSDAY NIGHT INTO FRIDAY...BRINGING
SIGNIFICANT RELIEF FROM THE HOT AND MUGGY CONDITIONS...AND
GREAT WEATHER FOR JULY 4TH FESTIVITIES. LOWS IN THE LOWER TO MID
60S ARE EXPECTED OVER THE NORTHERN HALF OF THE AREA FOR BOTH
FRIDAY AND SATURDAY MORNING. DRY CONDITIONS WILL CONTINUE SATURDAY
WITH ONLY SLIGHT RAIN CHANCES RETURNING FOR SUNDAY.

87/GRANTHAM

.AVIATION...
18Z TAF DISCUSSION.

SCATTERED SHOWERS/STORMS WILL CONTINUE ACROSS NE/E AL THRU THE
EARLY EVENING. ANB LOOKS TO BE THE ONLY TERMINAL THAT WILL BE
IMPACTED AT THIS TIME. HAVE REMOVED VCTS FROM ALL OTHER TAF
SITES...BUT WILL MONITOR IN CASE ANYTHING MANAGES TO DEVELOP A BIT
FARTHER WEST. WINDS WILL GENERALLY BE OUT OF THE WEST AROUND 5-10
KTS.

FOR TONIGHT...WITH SFC RIDGING BUILDING INTO THE AREA WINDS WILL
BE LIGHT/CALM AND SKIES WILL BE MOSTLY CLEAR TO PARTLY CLOUDY.
WITH SOME LOW LEVEL MOISTURE STILL IN PLACE PATCHY FOG COULD BE
POSSIBLE LATE TONIGHT TO NEAR SUNRISE. HAVE ONLY INCLUDED A
TEMPO FOR MVFR FOG AT MOST TERMINALS FOR NOW.
