AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
527 AM CST THU MAR 8 2012

.DISCUSSION...

THIS MORNING A COLD FRONT EXTENDED SOUTHWEST ACROSS SOUTHWEST
MISSOURI INTO NORTHEAST OKLAHOMA AND OUT OF THE SOUTHWEST PART OF
THE STATE AND ACROSS THE SOUTHERN PAN HANDLE REGION OF TEXAS INTO
SURFACE LOW PRESSURE. A RIDGE OF SURFACE HIGH PRESSURE ACROSS THE
GULF COAST STATES CONTINUED TO SUPPLY LOW LEVEL GULF MOISTURE NORTH
AS STRONG SOUTHERLY BOUNDARY LAYER WINDS OF 40 MPH AND SOUTHWEST LLJ
WINDS OF 45 TO 50 MPH ALSO HELPED TO SPREAD MOISTURE NORTH AHEAD
AND INTO THE FRONT. TO THE SOUTHWEST A CLOSED CUT OFF MID LEVEL LOW
OVER SOUTHWEST NEW MEXICO WAS CONTRIBUTING HIGHER PACIFIC MOISTURE
ACROSS THE AREA ALONG WITH A SERIES OF DISTURBANCES EJECTING AROUND
THE BASE AND TO THE EAST AND NORTHEAST IN THE SOUTHWEST FLOW
ALOFT. ANOTHER CENTRAL U.S. TROUGH WILL SEND THE COLD FRONT SOUTH
INTO THE FOUR STATE REGION TODAY. THIS COMBINATION WILL PROVIDE
WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS WITH A FEW OF THE
STORMS POSSIBLY SEVERE DURING THE AFTERNOON AND EVENING. DUE TO THE
HIGH MOISTURE CONTENT...RAINFALL WILL BE LOCALLY HEAVY PROVIDING
AMOUNTS OF ONE TO THREE INCHES THROUGH TONIGHT. THE COLD FRONT
IS EXPECTED TO MOVE TO NEAR THE GULF COAST ON FRIDAY WHERE IT
BECOMES NEARLY STATIONARY AND THEN MAKES A SLOW PUSH BACK NORTH
OVER THE FOUR STATE REGION SATURDAY NIGHT AND SUNDAY AS THE UPPER
LOW OVER THE SOUTHWEST SECTIONS OF THE COUNTRY LIFTS NORTHEAST
INTO THE ROCKIES. ADDITIONAL HEAVY RAINFALL WILL RETURN FOR
SATURDAY NIGHT INTO SUNDAY. ADDITIONAL HEAVY RAIN WILL PROVIDE SOME
LOCATIONS WITH AMOUNTS OF 4 TO 6 INCHES WITH ISOLATED HIGHER
AMOUNTS TO NEAR 8 INCHES. THE UPPER LOW WILL WEAKEN AS IT MOVES
INTO THE EASTERN SLOPES OF THE ROCKIES AND OUT INTO THE PLAINS
DURING THE LATE WEEKEND...BUT A TRAILING TROUGH OF LOW PRESSURE
WILL KEEP RAIN CHANCES GOING INTO THE START OF THE WORK WEEK. RAIN
STARTS TO TAPER OFF AFTER THE UPPER TROUGH PASSES EAST OF THE
REGION LATE MONDAY INTO THE EVENING SENDING A COLD FRONT EAST
RETURNING DRIER AIR. /06/

&&

.AVIATION...

COMPLICATED AND MESSY FORECAST EXPECTED FOR THE 12Z TAF PERIOD.
SCATTERED SHWRS ARE EXPECTED TO INCREASE IN INTENSITY AND COVERAGE
FROM NW TO SE AS A COLD FRONT SLOWLY APPROACHES. LOW OVC SHOULD
PERSIST THROUGH THE PERIOD. ANY TERMINALS EXPERIENCING IFR CIGS THIS
MORNING SHOULD IMPROVE TO MVFR BY 08/18Z. HOWEVER...EXPECT
DETERIORATING CONDITIONS AS SHWRS AND TSTMS BECOME MORE WIDESPREAD
AND A RETURN TO IFR CONDITIONS WILL BE POSSIBLE AFTER 09/00Z WHEN
THE HEAVIEST RAINFALL IS EXPECTED. IN ADDITION...ENOUGH INSTABILITY
WILL BE PRESENT TO SUPPORT A FEW STG TSTMS AHEAD OF THE COLD FRONT.
S/SE WINDS WILL SHIFT THE NORTH AS THE COLD FRONT MOVES ACROSS THE
AREA BEGINNING AROUND 08/18Z. WIND SPEEDS MAY BE GUSTY DURING THE
OVERNIGHT HOURS AS THE PRESSURE GRADIENT WILL BE RATHER TIGHT AFTER
THE FROPA. /09/
