AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
322 AM CDT TUE APR 24 2007

.SHORT TERM...
UPPER LEVEL LOW IS NOW MOVING EAST JUST EAST OF THE FOUR CORNERS
AREA. AS THIS SYSTEM APPROACHES...WINDS WILL INCREASE AS PRESSURE
GRADIENT AT THE SURFACE AND ALOFT TIGHTENS. MEANWHILE...DRYLINE HAS
BACKED UP INTO EASTERN NEW MEXICO BUT WILL BEGIN MOVING EAST TOWARD
12Z AS PACIFIC FRONT APPROACHES. KEPT A SLIGHT CHANCE OF TSTMS
IN ACROSS THE EXTREME EAST FOR A FEW HOURS THIS MORNING BEFORE THE
MOISTURE IS SCOURED EAST BY NOON.

MAIN ISSUE TODAY IS THE WINDS. GUIDANCE HAS BEEN CONSISTENT WITH
WIND SPEEDS THE PAST COUPLE OF RUNS...AND THAT SEEMS TO AGREE WELL
WITH FORECAST HEIGHT AND MID LEVEL WIND FIELDS. SURFACE WINDS WILL
INCREASE TO AROUND 30 TO 35 MPH FOR A FEW HOURS THIS AFTERNOON...
THUS WILL ISSUE WIND ADVISORY FOR THE ENTIRE FORECAST AREA. ALSO
EXPECT PATCHY BLOWING DUST ON THE CAPROCK. UPPER LOW WILL MOVE NEAR
THE OKLAHOMA PANHANDLE BY MIDNIGHT...WITH GRADIENT GRADUALLY
WEAKENING MID TO LATE EVENING. WILL SEE AN INCREASE IN LOW TO MID
LEVEL MOISTURE AND LIKELY SOME CLOUD COVER CLOSER TO UPPER LOW
ACROSS THE SOUTHERN PANHANDLE AND NW SOUTH PLAINS MID TO LATE
AFTERNOON. WINDS WILL VEER TO THE NORTHWEST THIS EVENING AS WEAK
COLD ADVECTION CONTINUES DURING THE OVERNIGHT HOURS AS SURFACE HIGH
PRESSURE BUILDS SE OUT OF THE CENTRAL ROCKIES/HIGH PLAINS. KEPT
SLIGHT CHANCE TSTMS ACROSS THE NW UNTIL MIDNIGHT. AS FAR AS TEMPS GO
TODAY...WILL SEE A DECENT GRADIENT FROM NW TO SE WITH HIGHS RANGING
FROM LOWER 70S SW PANHANDLE TO THE MID 80S SRN ROLLING PLAINS.
LOWS TONIGHT A LITTLE COOLER THAN NORMAL IN THE LOWER 40S TO LOWER
50S.

.LONG TERM...
COOLER AND BREEZY DAY IN STORE FOR WEDNESDAY AS UPR LOW SLIDES EAST
ACRS NORTHERN OKLAHOMA AND ALLOWS COLD FRONT TO MARCH SOUTH THROUGH
CENTRAL WEST TX. WRAP-AROUND LOWER AND MIDDLE LEVEL CLOUD COVER
SHOULD ALSO SLIDE SOUTH THROUGH MUCH OF THE NORTHERN AND EASTERN
CWFA. DUE TO MODEST COLD AIR ADVECTION AND ANTICIPATED CLOUD
COVER...HAVE DECIDED TO LOWER HIGHS INTO THE LWR/MID 60S ACROSS
THE NORTH...WITH MID 60S/NR 70 OVER THE SOUTH. GUSTY NORTHWEST TO
NORTH WINDS OF 20 TO 30 MPH WILL ADD A BIT OF A CHILL TO THE AIR.
COULD ALSO SEE A FEW SPRINKLES FLIRT WITH THE FAR NORTHEAST CORNER
OF THE CWA...BUT WILL LEAVE POPS LESS THAN 20 PERCENT.

NICE WEATHER EXPECTED ON THURSDAY AS WEAK H50 RIDGE TRANSLATES ACRS
THE REGION IN ADVANCE OF ANOTHER MID LEVEL DISTURBANCE PUSHING
SOUTH-SOUTHEAST THROUGH THE ROCKIES. THIS SHORTWAVE WILL MOVE CLOSE
ENOUGH ON FRIDAY TO WARRANT A SLIGHT CHC OF SHOWERS OR STORMS OVER
THE EASTERN 1/3 OF THE CWFA MAINLY FRIDAY AFTERNOON. ANY PRECIP
AMOUNTS SHOULD BE LIGHT DUE TO LIMITED MOISTURE.

WEEKEND WEATHER LOOKS IDEAL AT THIS TIME AS PRONOUNCED UPPER LEVEL
RIDGE BUILDS ACROSS MUCH OF THE SOUTH CENTRAL UNITED STATES.
EXTENDED MODELS FORECAST THIS RIDGE TO SLOWLY SLIDE EAST DURG EARLY
TO MID NEXT WEEK WITH SOUTHWEST FLOW RETURNING.

&&

.AVIATION...
WILL SEE PATCHY LOW CLOUDS/AROUND BKN010/THIS MORNING WITH CONTINUED
MOIST ADVECTION THROUGH 10-11Z AT KLBB AND PERHAPS A COUPLE HOURS
LONGER AT KCDS. WINDS WILL STAY UP AROUND 15 KNOTS...AND THEN VEER
TO THE SW AND INCREASE TO ADVISORY LEVELS THIS AFTERNOON. SHOULD SEE
VFR CONDS LATE THIS MORNING THOUGH LATE AFTERNOON...WITH AN INCREASE
IN LOW TO MID LEVEL MVFR CLOUDINESS AFTER 12Z WEDNESDAY MORNING AT
KCDS AND POSSIBLY AT KLBB.

&&

.FIRE WEATHER...
STRONG SURFACE WINDS OF 30 TO 35 MPH ALONG WITH AFTERNOON RELATIVE
HUMIDITIES IN THE 10 TO 15 PERCENT RANGE AND NFDRS RATING OF HIGH
ACROSS THE CENTRAL AND SOUTHERN SOUTH PLAINS EAST INTO THE ROLLING
PLAINS WILL PROMPT THE ISSUANCE OF RED FLAG WARNING TODAY. THE
NORTHERN SOUTH PLAINS AND SOUTHERN PANHANDLE WILL SEE HUMIDITIES A
LITTLE HIGHER...IN THE 15 TO 20 PERCENT RANGE DUE TO SLIGHTLY HIGHER
DEWPOINTS AND COOLER SURFACE TEMPS CLOSER TO UPPER LOW.
