AN UPPER LEVEL LOW WILL DROP SOUTHEAST TO THE TEXAS/NEW MEXICO

LOW CLOUD FIELD SHOULD ALSO DEVELOP ACROSS THE AREA NORTH
OF INTERSTATE 20. A MIX OF RAIN AND SNOW SHOWERS (TRANSITIONING
TO ALL SNOW SHOWERS) IS POSSIBLE FROM BY MID-AFTERNOON THROUGH

CORE ALOFT WITH THE SYSTEM ENTERS THE REGION.

PREV DISCUSSION... /ISSUED 605 PM CDT THU MAR 26 2009/

PREV DISCUSSION... /ISSUED 335 PM CDT THU MAR 26 2009/

SHORT TERM...
WARM...DRY...AND WINDY ACROSS THE CWA THIS AFTERNOON AS A DRY LINE
PUSHED THROUGH THE AREA BY EARLY AFTERNOON. EXPECT THE WINDY
CONDITIONS TO DIMINISH AS THE SUN SETS THIS EVENING AND MIXING IS
LOST...AS THE SFC PRESSURE GRADIENT IS NOT SUPPORTIVE OF THE CURRENT
WIND SPEEDS.

A POTENT UPPER LEVEL LOW IS CURRENTLY DIGGING SOUTH THROUGH WESTERN
CO/EASTERN UT. THIS UPPER LEVEL LOW WILL CONTINUE DIGGING SOUTH INTO
NM BEFORE TURNING TO THE EAST/NORTHEAST AND KICKING OUT ACROSS THE
TX SOUTH PLAINS AND OK TOMORROW. AT THE SURFACE...A VERY COLD AIR
MASS WILL BE POISED TO MOVE SOUTH INTO THE AREA MOST OF THE
NIGHT...ALLOWING OVERNIGHT TEMPERATURES TO REMAIN NEAR NORMAL OR
WARMER ACROSS MOST OF THE CWA. THIS COLD AIR WILL DIVE SOUTH INTO
THE CWA TOMORROW. THE COLDEST AIR IS NOT EXPECTED TO ARRIVE UNTIL
LATER IN THE DAY TOMORROW. AS THE LOW MOVES ACROSS THE TX SOUTH
PLAINS AND INTO OK TOMORROW...THERE WILL BE A SLIGHT CHANCE TO
CHANCE FOR PRECIPITATION ACROSS THE BIG COUNTRY AREA. HOWEVER... DUE
TO DRY MOVING IN ALOFT AROUND THE SOUTH SIDE OF THE UPPER LEVEL LOW
LIMITING THE AMOUNT OF AVAILABLE MOISTURE...WE ARE GOING TO KEEP
POPS LOW. DUE TO VERY COLD AIR ALOFT...SOME OF THIS PRECIPITATION
COULD BE A MIX OF RAIN AND SNOW. HOWEVER...SINCE TEMPERATURES ARE
EXPECTED TO REMAIN ABOVE FREEZING THROUGHOUT THE DAY...NO
ACCUMULATIONS ARE EXPECTED. EVEN SO...WITH THE COMBINATION OF STRONG
WINDS AND MIXED PRECIP...ROADS COULD BECOME SLICK...MAKING DRIVING
CONDITIONS HAZARDOUS...ESPECIALLY BY THE AFTERNOON HOURS FRIDAY.

LONG TERM...
UPPER LEVEL LOW WILL MOVE QUICKLY NORTHEAST OUT OF THE AREA
SATURDAY TO A POSITION OVER THE MID MISSISSIPPI VALLEY BY SATURDAY
EVENING. AFTER AN UNSEASONABLY COLD START TO THE DAY SATURDAY
MORNING WITH TEMPERATURES IN THE LOWER 30S...TEMPS WILL REBOUND
DURING THE DAY WITH AFTERNOON HIGHS AROUND 60. SUNDAY WILL AGAIN
SEE MORNING LOWS IN THE 30S WITH AFTERNOON HIGHS WARMING TO THE
SEASONABLE 70S.

THE NEXT COUPLE OF WEST COAST UPPER LEVEL SYSTEMS WILL PASS OVER
THE CENTRAL PLAINS KEEPING ANY ASSOCIATED RAINFALL NORTH OF THE
AREA. WILL SEE DRY WEAK FRONTAL PASSAGES ON MONDAY AND THURSDAY
OF THE COMING WEEK WITH PRE-FRONTAL DAYTIME HIGHS IN THE 80S AND
POST FRONTAL DAYTIME HIGHS IN THE 70S. MORNING LOWS SHOULD RANGE
FROM THE MID 40S TO LOW 50S. A DRY WEATHER PATTERN WILL CONTINUE
THROUGH THE EXTENDED.

FIRE WEATHER...
THE RED FLAG WARNING WILL REMAIN IN EFFECT THROUGH 7PM TONIGHT AS
WEST TO SOUTHWEST WINDS GREATER THAN 20 MPH...COMBINED WITH VERY
WARM TEMPERATURES AND RELATIVE HUMIDITY VALUES WILL CONTINUE THROUGH
THE REST OF THE AFTERNOON ACROSS THE CONCHO VALLEY...BIG COUNTRY AND
NORTHERN EDWARDS PLATEAU. VERY POOR RECOVERY WILL TAKE PLACE ACROSS
THE CONCHO VALLEY AND NORTHERN EDWARDS PLATEAU TONIGHT...BUT WINDS
ARE EXPECTED TO DIMINISH SHORTLY AFTER SUNSET AS MIXING CEASES.
TOMORROW...MUCH COLDER AIR WILL MOVE IN KEEPING RELATIVE HUMIDITY
VALUES ABOVE 20 PERCENT...BUT WINDS WILL BE JUST AS STRONG...IF NOT
STRONGER OUT OF THE NORTHWEST...ESPECIALLY BY LATE MORNING AND
AFTERNOON. ELEVATED CONDITIONS WILL REMAIN IN THE AREA THROUGHOUT
THE NEXT 7 DAYS WITH WARMING TEMPERATURES AND RELATIVE HUMIDITY
VALUES FALLING TO LESS THAN 25 PERCENT ACROSS THE AREA EACH DAY. THE
ONE LIMITING FACTOR TO REACHING CRITICAL LEVELS AT THIS TIME APPEARS
TO BE WIND SPEEDS.
