Severe Thunderstorm Warning 213, NWS Lubbock, TX

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
205 PM CDT WED SEP 22 2004

.SHORT TERM...
COLD FRONT CURRENTLY MOVING THROUGH THE TEXAS PANHANDLE WILL
CONTINUE TO MOVE SLOWLY TO THE SOUTH AND EAST DURING THE EVENING AND
OVERNIGHT HOURS. THUNDERSTORMS CONTINUE TO FIRE ALONG AND JUST AHEAD
OF THE FRONT...PRODUCING SOME LOCALLY HEAVY RAINFALL ALONG THE
INTERSTATE 40 CORRIDOR. WHILE SCATTERED THUNDERSTORMS WILL OCCUR
OVER THE AREA TONIGHT...BEST SHOT AT PROLONGED PRECIPITATION WILL BE
IN THE NORTHERN AND NORTHEASTERN COUNTIES THROUGH MIDNIGHT...BEFORE
SLOWLY DRIFTING EAST. WILL NOT BE TERRIBLY SURPRISED TO SEE A FEW
LOCALIZED AREAS OF HEAVY RAINFALL...AND LOCALIZED RUNOFF IN
TRADITIONALLY LOW LYING AREAS IS A DISTINCT POSSIBILITY TONIGHT. LOW
POPS WILL THEN DECREASE FROM WEST TO EAST DURING THE DAY ON
THURSDAY...BEFORE DIMINISHING FURTHER EARLY FRIDAY.

TIMING OF THE COLD FRONT IS THE NEXT ISSUE. PREVIOUS SHIFT HAD THE
FRONT COMING THROUGH THE SOUTHERN HALF OF THE AREA BY 12Z THURSDAY.
CAN NOT ARGUE WITH THIS SCENARIO GIVEN THE LATEST SHORT RANGE MODELS
AND HAVE KEPT THE INTEGRITY OF THE FORECAST INTACT. FIRST FULL DAY
OF FALL WILL SEE BELOW NORMAL TEMPERATURES...BUT WILL ACTUALLY BE A
FEW DEGREES WARMER THAN TODAY.

.LONG TERM...
WILL CONTINUE WITH CURRENT FORECAST OF A FEW SHOWERS LINGERING
ACROSS THE SOUTHEAST LOW ROLLING PLAINS FRIDAY MORNING. DRIER AIR
THEN TO MOVE INTO THE FA DURING THE DAY FRIDAY. MODELS INDICATED
UPPER LOW OVER MINNESOTA EARLY FRIDAY AND LIFTING NORTHEAST INTO
MANITOBA AND ONTARIO PROVINCES OF CANADA DURING THE DAY FRIDAY WITH
ATTENDANT TROUGH EXTENDING SOUTHWEST INTO ARIZONA. MODELS THEN
CONTINUE TO KEEP THIS TROUGH AXIS FROM ARIZONA NORTHEAST INTO
MISSOURI THROUGH THE WEEKEND. SURFACE FLOW TO RETURN TO THE EAST
SOUTHEAST DURING THE WEEKEND AS SURFACE HIGH PRESSURE SLOWLY
TRANSLATES TO THE EAST. COULD SEE SOME CONVECTION DEVELOP OVER THE
HIGHER TERRAIN OF NEW MEXICO OVER THE WEEKEND AND TRY TO APPROACH
THE NORTHWEST PORTIONS OF THE CWFA. STILL A LOT OF UNCERTAINTIES ON
MODELS GOING INTO NEXT WEEK AS MODELS CONTINUE TO INDICATE AN UPPER
LEVEL TROUGH DEVELOPING ACROSS THE PLAINS. GFS INDICATED UPPER
TROUGH EXTENDING SOUTH ACROSS EASTERN NEW MEXICO. HAVE DECIDED TO
ADD SLIGHT CHANCE POPS FOR MONDAY AFTERNOON/EVENING. MADE MINOR
TWEAKS TO THE CURRENT LONGRANGE PERIODS. MODELS LEANING TOWARD COOL
AND WET PATTERN NEXT WEEK. HOWEVER WOULD LIKE TO SEE ANOTHER MODEL
RUN OR TWO BEFORE ADDING POPS AND LOWERING TEMPERATURES. XI
