Area forecast discussion, Mar 22, 4:30 AM CDT, 5 hours before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
430 AM CDT THU MAR 22 2012

.DISCUSSION...
DEEP COLD CORE UPPER LOW WILL CONTINUE TO SPIN ACROSS CENTRAL OK
TODAY...BEFORE SLOWLY MOVG INTO SW MO TONIGHT. SFC FEATURES HAVE
LONG SINCE OCCLUDED WITH DIFFUSE FRONTAL BOUNDARY WELL TO EAST OF
UPPER LOW..NEAR THE MISSISSIPPI RIVER VALLEY. BACK EDGE OF PCPN
ASSOCIATED WITH THIS BOUNDARY HAS SHIFTED JUST EAST OF THE RIVER...SO
WILL NOT INCLUDE ANY POPS WITH THIS ACTIVITY. HOWEVER...BAND OF
SHALLOW CONVECTION WRAPPING AROUND SE SIDE OF THIS UPPER LOW..AND
APPROACHING RED RIVER VALLEY BORDERING OK/TX. STEEP LAPSE RATES
AND SFC HEATING SHOULD YIELD STGR CONVECTION BY MIDDAY WITH THE
CURRENT SHOWERS AND THEY SHIFT EAST. WITH LOW LVL DRYNESS OF
AIR...AND SATURATION IN MID LVLS...SEE ENHANCED THREAT FOR STG
GUSTY WINDS IN ANY STORMS THAT DEVELOP...AS WELL AS THREAT FOR AT
LEAST SMALL HAIL AS MID LVL TEMPS AROUND -20C IN SE OK. MOST OF
THIS STRONGER CONVECTION WILL LIKELY MISS CWA TO THE NORTH...BUT
NAM IS BRINGING TRACK OF UPPER LOW SLIGHTY FURTHER SOUTH THAN IS
GFS AND ECMWF.
BROAD UPPER RIDGING WILL MOVE OVER THE REGION THIS WEEKEND...AND
MOSTLY SUNNY SKIES AND HIGH TEMPERATURES MAINLY IN THE LOWER TO
MID 80S CAN BE EXPECTED. EVENTUALLY...TROUGHING TO DEVELOP OVER
THE PLAINS NEXT WEEK...FOR NOW WILL GRADUALLY INTRODUCE LOW POPS
FROM THE WEST LATER IN THE EXTENDED PERIOD.
A NARROW ZONE OF DENSE FOG DEVELOPMENT IS POSSIBLE EARLY THIS
MORNING ACROSS EASTERN CWA...WHERE CLEAR SKIES EXIST JUST WEST
CLOUD DECK OVER MISSISSIPPI RIVER VALLEY...AND ALTOCU ADVANCING
EASTWARD ACROSS NW LA. VERY WET GROUND AND WINDS LIGHT SO
CONDITIONS ARE PRIME...AND VSBYS BEGINNING TO FALL AT A FEW
LOCATIONS...BUT WINDOW OF OPPORTUNITY TOO NARROW WITH ADVANCING
MID LVL CLOUDS TO WARRANT DENSE FOG ADVISORY AT THIS TIME. PLACED
AREAS OF FOG FOR THE EARLY MORNING...BUT WILL CONTINUE TO MONITER./VII/.

&&

.AVIATION...

VFR FLIGHT CATEGORIES REMAIN COMMON ACROSS MUCH OF THE AREA THIS
MORNING...AND THIS SHOULD CONTINUE THROUGH THE 12Z TAF PERIOD. WE
COULD SEE SOME TEMPO IFR CONDITIONS AT ELD AND MLU AT THE START OF
THE 12Z TAF PERIOD...BETWEEN 12Z AND 14Z. AN UPPER LOW CURRENTLY IN
THE SOUTHERN PLAINS WILL ROTATE SOME MID LEVEL CLOUDS ACROSS THE
AREA DURING THE DAY...AND ISOLATED TO SCATTERED -SHRA ACTIVITY WILL
NOT BE OUT OF THE QUESTION FOR TXK AND THE EAST TEXAS I20 TERMINALS.
SOUTHERLY WINDS OF 5 TO 10 KTS WILL AGAIN BE COMMON...THEN BECOMING
LIGHT AND VARIABLE OVERNIGHT AS A WEAK BOUNDARY ENTERS THE AREA.
