PLAINS. THIS FEATURE AIDED IN PRODUCING A FEW SHOWERS OVER THE
LOW ROLLING PLAINS DURING THE LATE MORNING AND EARLY AFTERNOON.
THERE WAS ALSO A WEAK SURFACE BOUNDARY EXTENDING ACROSS CHILDRESS
COUNTY INTO THE TEXAS PANHANDLE ASSOCIATED WITH THIS FEATURE.
ANOTHER IMPULSE IS SEEN ON WATER VAPOR MOVING INTO FAR WEST TEXAS
WITH DIFFLUENT AREA OVER SOUTHEAST NEW MEXICO. SURFACE ANALYSIS
ALSO HAS A CONVERGENCE AREA OVER SOUTHEAST NEW MEXICO AT 18Z.
PLENTY OF LOW LEVEL MOISTURE WITH 50 DEW POINTS BANKED UP AGAINST
THE MOUNTAINS AND 60S MOVING ACROSS OUR SOUTHEAST ZONES. WITH
CONTINUED SOUTHEAST FLOW AND STRENGTHENING LOW LEVEL JET...LOW
LEVEL MOISTURE TO CONTINUE MOVING INTO THE FORECAST AREA DURING
THE NIGHT. CURRENTLY CONVECTION SEEN DEVELOPING OVER THE MOUNTAINS
OF NEW MEXICO...HOWEVER EXPECT CONVECTION TO BEGIN DEVELOPING OVER
THE EASTERN PLAINS OF NEW MEXICO NEXT FEW HOURS AND THEN MOVE INTO
THE SOUTH PLAINS AND TEXAS PANHANDLE. WITH GOOD SHEAR AND FAIRLY
STEEP LAPSE RATES...SOME OF THESE STORMS MAY BECOME SEVERE AS
THEY ROLL INTO THE FORECAST AREA. WITH HIGH DEW POINT TEMPERATURE
ACROSS THE REGION...LOWS TUESDAY MORNING TO BE WELL ABOVE NORMAL.
AFTER A LULL IN THE ACTION TUESDAY MORNING...WHILE ATMOSPHERE

COAST MOVES TOWARD SOUTHEAST ARIZONA BY LATE AFTERNOON AND THE DRY

.LONG TERM...
THE GENERAL TREND IN THE LONG TERM GRIDS WILL BE A TRANQUIL WEATHER
PATTERN AFTER THE UPPER LOW TRANSLATES OUT OF THE AREA TO THE EAST
ON WEDNESDAY. PRECIPITATION CHANCES WILL BE ON THE INCREASE TUESDAY
EVENING AS THE UPPER LOW EDGES CLOSER TO THE AREA ALONG WITH THE JET
ENERGY ASSOCIATED WITH IT. A SHARP DRYLINE SHOULD SHARPEN UP BY THE
EVENING HOURS WITH STEEP MIDLEVEL LAPSE RATES EAST OF THE DRYLINE.
A STRONG SURFACE CAP SHOULD ALSO SIGNIFICANTLY WEAKEN BY THE
EVENING HOURS. MOISTURE WILL STAY IN PLACE FOR MOST OF THE EVENING
AND NIGHTTIME HOURS BEFORE THE DRYLINE BEGINS TO MIX EAST EARLY ON
WEDNESDAY. IN ADDITION...MODERATE TO STRONG SHEAR WITH STRONG
INSTABILITY WILL PROMOTE SOME POSSIBLE SEVERE STORMS OVERNIGHT
TUESDAY INTO WEDNESDAY MORNING. AS THE UPPER LOW SLIDES OFF TO THE
EAST...MOST OF THE PRECIPITATION CHANCES WILL END FROM WEST TO
EAST BY LATE WEDNESDAY MORNING.

CRITICAL FIRE WEATHER CONDITIONS COULD THEN DEVELOP ON WEDNESDAY
AFTERNOON ACROSS THE SOUTHWESTERN SOUTH PLAINS. WINDS WILL PICK UP
BEHIND THE FRONT BUT POSSIBLY STILL BELOW CRITICAL THRESHOLDS. A
QUIET WEATHER PATTERN WILL ENSUE FOR THE REST OF THE WEEK IN
GENERALLY ZONAL FLOW. A FRONT MAY PUSH THROUGH SOMETIME LATE
