.SHORT TERM...
LATEST ANALYSIS CONTINUES TO DEPICT THIS MORNING/S FRONTAL BOUNDARY
BISECTING THE FA. SATELLITE/RADAR TRENDS SHOW INCREASING CONVECTION
ALONG THE MOUNTAINS OF NEW MEXICO...AND INCREASING CU OVER THE
OKLAHOMA/TEXAS PANHANDLE. EXPECT A CONVECTIVE COMPLEX TO ORGANIZE
OVER THOSE REGIONS AND PROPAGATE SOUTHEASTWARD TOWARD THE NORTHERN
ZONES TONIGHT. SHEAR/INSTABILITY CONTINUE TO REMAIN SUFFICIENT FOR A
SLIGHT CHANCE OF SEVERE WEATHER WITH THIS ACTIVITY...WIND AND HAIL
THE PRIMARY THREATS.

A SECOND SURGE OF COOL/CONVECTIVELY ENHANCED RIDGING WILL PUSH
THROUGH THE FA EARLY WEDNESDAY. EXPECT LINGERING CLOUD COVER AT
LEAST THROUGH THE MIDDAY HOURS...WITH COOLER TEMPERATURES. DRIER AIR
WILL ALSO FILTER SOUTH IN THE WAKE OF TOMORROW/S FROPA...SO THE
CHANCE OF STORMS APPEARS TO BE LIMITED EXCEPT PERHAPS OVER THE
SOUTHWESTERN FA IN PROXIMITY TO THE BOUNDARY.

.LONG TERM...
STRONG UPPER TROUGH TRANSLATING EAST ACROSS THE CENTRAL PLAINS AND
MIDWEST WEDNESDAY NIGHT SHOULD FORCE ANOTHER COOL SURGE THROUGH
THE SOUTH PLAINS BY THURSDAY MORNING. THIS WILL KEEP TEMPERATURES
IN THE LOWER TO MIDDLE 70S WITH SURFACE HIGH PRESSURE BUILDING
OVER THE SOUTH PLAINS FROM THE NORTH.

THE SURFACE HIGH WILL BUILD EAST BY FRIDAY WITH A RETURN TO
SOUTHERLY FLOW AND STRENGTHENING UPPER LEVEL RIDGE OVER THE FOUR
CORNERS TO END THE WEEK. LOW LEVEL MOISTURE WILL RETURN TO THE
REGION BY FRIDAY AFTERNOON BUT STOUT RIDGE SHOULD SUPPRESS
CONVECTIVE ACTIVITY.

BUILDING RIDGE WILL ALLOW DAYTIME MAXIMA TO WARM INTO THE 80S TO
NEAR 90 BY SATURDAY BEFORE ANOTHER COLD FRONT APPROACHES THE SOUTH
PLAINS LATER SATURDAY OR SUNDAY.

UPPER TROUGH IS FORECAST TO DEEPEN OVER THE EASTERN TWO THIRDS BY
SUNDAY AND MONDAY WITH NORTHWEST TO NORTHERLY FLOW ALOFT
SHARPENING OVER THE SOUTH PLAINS. IF THIS SUMMER LIKE PATTERN
VERIFIES...LOW LEVEL MOISTURE SHOULD REMAIN IN PLACE WITH
DESTABILIZATION ALOFT OCCURRING AS COLD AIR INTRUDES ALOFT.
THUNDERSTORM COMPLEXES DEVELOPING OVER NORTHEAST NEW MEXICO/SE
COLORADO COULD AFFECT THE REGION FROM SATURDAY NIGHT THROUGH
MONDAY NIGHT. CHANCE POPS LOOK GOOD AT THIS TIME. ANY ACTIVITY
THAT DOES DEVELOP COULD BE STRONG TO LOCALLY SEVERE. CONFIDENCE
STILL TOO LOW FOR ELEVATED MENTION.

LONG RANGE GFS KEEPS THE SHARP NORTHERLY FLOW ALOFT PATTERN WITH A
SERIES OF WEAK COLD FRONTS AFFECTING THE REGION THROUGH THE MIDDLE
OF NEXT WEEK. ONLY MINOR CHANGES MADE TODAY. KW
