AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
1115 PM CDT TUE OCT 21 2014

.AVIATION...
AS EXPECTED...STARTING TO SEE SOME SCATTERED CLOUDS ON IR IMAGERY
ACROSS PORTIONS OF THE REGION. THESE CLOUDS HEIGHTS ARE AROUND
4-5KFT AND SHOULD NOT POSE ANY PROBLEMS OVERNIGHT. WE ARE STARTING
TO SEE SOME VSBY ISSUES HOWEVER AT ELD AND MLU WITH 2-5 MILES
BEING OBSERVED ATTM. THE LEADING EDGE OF A MUCH DRIER AIRMASS
CONTINUES TO SLOWLY BACKDOOR ITS WAY INTO CENTRAL ARKANSAS AND
NORTHERN MISS ATTM. THIS BOUNDARY IS STILL PROGD TO MOVE INTO OUR
REGION FROM THE NORTHEAST AND BACKDOOR ITS WAY THROUGH THE REGION
DURING THE DAY WEDNESDAY. HOPEFULLY THIS DRIER AIR MOVES INTO THE
ELD/MLU TERMINALS BEFORE SUNRISE OR WE COULD SEE VSBYS CONTINUE TO
CRATER. FOR THIS REASON...PREVAILED MVFR VSBYS AT ELD AND MLU WITH
A MUCH LOWER TEMPO GROUP OVERNIGHT.

OTHERWISE VFR CONDITIONS ARE EXPECTED TO CONTINUE THROUGHOUT THE
DAYTIME HOURS ON WEDNESDAY WITH NE WINDS PREVAILING NEAR 5-8KTS ON
WED.

.PREV DISCUSSION... /ISSUED 953 PM CDT TUE OCT 21 2014/

DISCUSSION...
UPPER RIDGE AXIS IS ROUGHLY OVER THE OK/AR AND TX/LA BORDERS. WEAK
BACK DOOR FRONT STILL REMAINS NE OF THE AREA. LATEST WV LOOPS
INDICATE DRY AIR ALOFT IS BEING DISPLACED TO THE NE AS A WEAK
UPPER WAVE MOVES EWD ACROSS S TX. SOME INCREASED HIGH CLOUDS MAY
MOVE INTO THE AREA OVERNIGHT AS THIS WAVE MOVES CLOSER. THIS COULD
KEEP OUR TEMPERATURES A DEGREE OR TWO WARMER THAN CURRENTLY FCST.
HOWEVER...CURRENT THINKING IS THE ARRIVAL OF THE BACKDOOR COLD
FRONT WILL BRING ENOUGH COOL AND DRY AIR TO OFFSET THE INCREASED
CLOUDS. THEREFORE...WILL LEAVE MIN TEMP FCST INTACT FOR
TONIGHT/WEDNESDAY MORNING BUT DID MAKE SOME MINOR TWEAKS TO THE
HOURLY TEMP TRENDS. OTHER MINOR ADJUSTMENTS WERE MADE TO
DEWPOINT/WIND/SKY GRIDS BASED ON LATEST OBS.

UPDATED TEXT PRODUCTS WILL BE SENT SHORTLY. /09/
