AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL

.UPDATE...
NO CHANGES ARE NEEDED.

.DISCUSSION...
MID/UPPER LEVEL RIDGING (WITH MAX HEIGHTS IN THE 592/593 DECAMETER
RANGE) SITUATED FROM WEST TEXAS TO THE MID ATLANTIC CONTROLLED THE
GENERAL WEATHER SITUATION ACROSS THE REGION THIS EVENING. 9 PM
TEMPERATURES HAVE COOLED INTO THE UPPER 60S TO UPPER 70S WITH LIGHT
WINDS. DEWPOINT VALUES MAINLY IN THE MID/UPPER 60S MAKE FOR MORE
COMFORTABLE CONDITIONS COMPARED TO THE PAST WEEKEND. ISOLATED TO
WIDELY SCATTERED STORMS THAT AFFECTED LOCATIONS MOSTLY TO OUR WEST
HAVE DISSIPATED WITH A LOSS OF DAYTIME HEATING.

TONIGHT UNDER CLEAR SKIES...OVERNIGHT LOWS SHOULD FALL INTO THE MID
60S IN MOST SPOTS. THOSE VALUES WILL APPROACH DEWPOINT VALUES...
THUS PATCHY FOG DEVELOPMENT IS A GOOD POSSIBILITY...ESPECIALLY IN
THOSE FAVORED FOG PRONE AREAS (NEAR LARGE BODIES OF WATER AND IN
SHELTERED VALLEYS). THE ON-GOING FORECASTS FROM THE DAYSHIFT ARE IN
GOOD SHAPE...THUS NO UPDATES ARE NEEDED AT THIS TIME.

.AVIATION...
/ISSUED 640 PM CDT TUE AUG 26 2014/
FOR 00Z TAFS...
VFR CONDITIONS AND LIGHT WINDS SHOULD CONTINUE INTO THE LATE
NIGHT...AS A WEAK EASTERLY FLOW PREVAILS ACROSS THE REGION. THE
LIGHT WINDS AND MOSTLY CLEAR SKIES COULD RESULT IN PATCHY MVFR
FOG FORMING AROUND DAYBREAK WED. ANY FOG THAT FORMS SHOULD
DISSIPATE SHORTLY AFTER SUNRISE...WITH VFR WEATHER CONTINUING FOR
THE REMAINDER OF THE TAF.

.PREV DISCUSSION...
/ISSUED 422 PM CDT TUE AUG 26 2014/
THE MAJORITY OF THE SHOWERS AND THUNDERSTORMS HAVE STAYED TO OUR
NORTHWEST WITH ONLY A FEW SHOWERS MAKING IT INTO OUR NW COUNTIES
TODAY. ADDED IN PATCHY FOG TO THE FORECAST FOR LOCATIONS NEAR BODIES
OF WATER AND IN VALLEYS. WITH NEARLY CALM WINDS AND DECREASING CLOUDS
TO A MOSTLY CLEAR SKY...EVEN WITH THE LOWER DEWPOINTS IN THE AREA
SOME LOCATIONS COULD SEE FOG. CLOUD COVER THROUGHOUT THE DAY HELD
BACK THE TEMPS FROM REACHING INTO THE 90S TODAY...BUT TEMPS WILL GET
DOWN INTO THE MID 60S TONIGHT. THESE TEMPS COUPLED WITH THE LOWER
DEWPOINTS WILL MAKE FOR A PLEASANT EVENING ACROSS THE TN VALLEY.

WITH HIGH PRESSURE MOVING BACK OVER THE SOUTHEASTERN STATES...DRY
CONDITIONS ARE EXPECTED THROUGH THE WORK WEEK. SOUTHERLY FLOW WILL
BEGIN TO RETURN ON THURSDAY AHEAD OF A TROUGH MOVING THROUGH THE
MIDWEST AND THE HIGH MOVING OFF INTO THE ATLANTIC. THE GULF MOISTURE
WILL ALLOW PWATS TO INCREASE OVER AN INCH ON FRIDAY AND UP TO 2 INCHES
ON SATURDAY. SHOWERS AND THUNDERSTORMS COME BACK INTO THE FORECAST
FRIDAY AFTERNOON AND SATURDAY AS DISTURBANCES MOVE ACROSS THE TN
VALLEY. THE PATTERN WILL REMAIN UNSETTLED INTO THE BEGINNING OF THE
NEXT WORK WEEK.

AS FOR TEMPS...LOW TO MID 90S THROUGH THURSDAY WITH FRIDAY LEADING
THE SLIGHT DECREASE TREND WITH LOWER 90S...WHICH IS OUR NORM. THE
WEEKEND MAY NOT REACH THE 90S...BUT WE WILL BE BACK TO NORMAL TEMPS
THROUGH THE NEXT WORK WEEK. OTHERWISE LOWS WILL BE IN THE UPPER 60S
TO AROUND 70 DEGREES THROUGH THE FORECAST PERIOD.
