AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
339 AM CDT WED JUN 20 2007

.SHORT TERM...
IMPRESSIVE MCS INTERACTIONS EARLY THIS MORNING AS THE COMPLEX
CHARGES EASTWARD INTO NORTH TEXAS. STILL A BIT OF CONVECTION TRYING
TO HANG ON WEST OF THE MCS BUT BELIEVE THIS WILL DISSIPATE RATHER
FAST THROUGH THE EARLY MORNING.

RAIN CHANCES WILL NOT BE MENTIONED FOR THE AFTERNOON AND EVENING AS
THE ATMOSPHERE SLOWLY RECOVERS. WILL TAKE A SIGNIFICANT PORTION OF
THE MORNING BEFORE WE SEE A RETURN TO THE SOUTHEASTERLY WINDS.
CLOUD COVER WILL ALSO TAKE ITS TIME CLEARING OUT AND WILL BE THE
LATEST ACROSS THE EASTERN ZONES. THE RAINFALL AND CLOUD COVER WILL
HAVE AN IMPACT ON TEMPERATURES. WITH THAT IN MIND WE DECIDED TO LEAN
TOWARDS THE COOLER GUIDANCE FOR TODAY WITH HIGHS WITHIN A FEW
DEGREES OF 90.

.LONG TERM...
MODELS IN GOOD AGREEMENT WITH MID LEVEL RIDGE EXTENDING NORTHWARD
FROM A 500 MB HIGH OVER NEW MEXICO EXPECTED TO TILT NORTHEASTWARD
INTO THE NORTHERN PLAINS THROUGH THE END OF THE WEEK AND INTO THE
WEEKEND AS A DEEP LOW MOVES OUT OF THE GULF OF ALASKA INTO THE
PACIFIC NORTHWEST. RIDGE BEGINS TO FLATTEN WITH CENTER OF HIGH
MOVING TOWARD THE SOUTHEASTERN U.S. AT THE BEGINNING OF NEXT WEEK
AS THE LOW MOVES EAST ALONG THE CANADIAN BORDER/SOUTHERN CANADA.
ALTHOUGH WITH SOME DIFFERENCES MODELS ALSO INDICATE A WEAK LOW
MOVING WESTWARD ACROSS TEXAS...ON SOUTHERN PERIPHERY OF MID LEVEL
HIGH DURING THE EARLY TO MID PART OF NEXT WEEK. AND ALTHOUGH
CANNOT COMPLETELY RULE OUT POSSIBILITY OF SOME CONVECTION FOR
THE EARLY AND MID PART OF NEXT WEEK WILL CONTINUE WITH DRY
FORECAST FOR NOW. WITH UPPER RIDGE OVER THE REGION EXPECT DAYTIME
HIGHS TO REMAIN IN THE 90S ACROSS THE AREA THROUGH THE FORECAST
PERIOD. ALL IN ALL NO MAJOR CHANGES MADE TO PREVIOUS FORECAST.
