.SHORT TERM...
SURFACE RIDGE SLIDING ACROSS THE SOUTHEAST CONUS TODAY IN
CONJUNCTION WITH DEVELOPING SURFACE TROUGHING NEAR THE TEXAS/NEW
MEXICO STATE LINE WILL BRING A RETURN TO SOUTH/SOUTHWEST SURFACE
WINDS AND SUBSEQUENT WARMING INTO THE UPPER 80S TO MID 90S THIS
AFTERNOON. STRENGTHENING LOW LEVEL JET ACROSS THE TEXAS PANHANDLE
INTO SOUTHWEST KANSAS WILL NOSE INTO THE FAR SOUTHERN PANHANDLE THIS
MORNING...POTENTIALLY SPARKING AN ISOLATED SHOWER OR STORM ALTHOUGH
MORE THAN LIKELY REMAINING NORTH OF THE FAR SOUTHERN PANHANDLE.

BEST GLIMMER OF HOPE FOR PRECIPITATION WILL COME THIS EVENING INTO
TONIGHT FOLLOWING DIURNAL HEATING AND INCREASING INSTABILITY TO 1.5-
2 KJ/KG AS A 35-45 KNOT UPPER JET NOSES THROUGH THE TEXAS PANHANDLE.
LEFT EXIT REGION OF THIS FEATURE WILL BE LOCATED ACROSS THE FAR
SOUTHEASTERN TEXAS PANHANDLE INTO THE ROLLING PLAINS...PERHAPS
LEADING TO BETTER DEEP LAYER LIFT. HOWEVER...STRONGER H85 WIND
FIELDS WILL BE AVAILABLE WEST OF THE CAPROCK ESCARPMENT TO FEED INTO
ANY SOUTHWARD PROPAGATING ACTIVITY. DEEP LAYER SHEAR OF AROUND 20
KNOTS MAY BE JUST ENOUGH TO ALLOW A FEW CELLS TO HOLD TOGETHER FOR A
SHORT TIME...WITH THE PRIMARY HAZARD COMING IN THE FORM OF STRONG
DOWNBURST WINDS BENEATH A SUB-CLOUD DRY LAYER AS FAIRLY WARM MID
LEVEL TEMPERATURES AND THE CONTINUED PRESENCE OF A SUBSIDENCE
INVERSION KEEP EQUILIBRIUM LEVELS LOW ENOUGH TO PRECLUDE THE
DEVELOPMENT OF SIGNIFICANT HAIL. LIGHT SOUTH/SOUTHWEST BREEZES
COMBINED WITH A WARM AIRMASS OVERNIGHT WILL KEEP TEMPERATURES IN THE
MID 60S-LOW 70S.

.LONG TERM...
PRIMARY INFLUENCE OF OUR WEATHER IN THE EXTENDED WILL BE THE STRONG
DOME OF HIGH PRESSURE OVER THE GREAT BASIN WHICH LOOKS TO PERSIST
THROUGH 240 HOURS.  THE INFLUENCE OF COURSE IS THE SYNOPTIC SCALE
INTERACTION WITH THE JET WHICH DIVES SOUTH ACROSS THE SOUTHEASTERN
PART OF THE COUNTRY.  MID LEVEL FLOW WILL CONTINUE TO BE
NORTHWESTERLY INTO MONDAY BEFORE A BIT OF A GYRATION OCCURS WITH THE
HIGH THUS VEERING THE FLOW TO A MORE NORTHERLY DIRECTION FOR TUESDAY
AND THENCE NORTHEASTERLY INTO WEDNESDAY.  AFTER A BIT OF A
REORGANIZATION OF THE HIGH...THURSDAY INTO FRIDAY SEES A BACKING OF
THE WINDS ONCE AGAIN WHICH PERSIST THROUGH NEXT WEEKEND.  WITHIN THE
MEAN FLOW...A FEW EMBEDDED SHORTWAVE TROUGHS ARE ANTICIPATED TO PASS
TO OUR NORTHEAST THE FIRST OF WHICH WHICH WILL TRAVERSE THURSDAY
MORNING NIGHT WITH PROGRESSIVELY STRONGER TROUGHS INTO NEXT WEEKEND.

TSTM ACTIVITY STILL LOOKS POSSIBLE MONDAY INTO MONDAY NIGHT AS A
WEAK FRONTAL BOUNDARY SINKS INTO THE REGION.  BY TUESDAY MORNING
HOWEVER...CONDITIONS RAPIDLY DRY OUT WITH SOUTHERLY FLOW INDICATED
BY MOST ALL THE SOLUTIONS.  AS THE FLOW BACKS TO A MORE
NORTHWESTERLY VECTOR...TSTMS WILL FIRE ACROSS THE ELEVATED TERRAIN
OF NERN NM AND DRIFT SOUTHEASTWARD.  AS THERE ARE HINTS THAT THE
ACTIVITY COULD PERSIST WELL INTO THE NIGHT...WILL MAINTAIN SLGT CHC
POPS UP IN THE NORTHWEST ON THURSDAY.  IN GENERAL...THE EXPECTATION
IS THAT LATE NIGHT TSTM ACTIVITY WILL THEN PERSIST EACH NIGHT INTO
THE WEEKEND.  ALL IN ALL...ALMOST THE SAME STORY DAY AFTER DAY FOR
THE NEXT WEEK WITH THE EXCEPTION OF A DRIER TUESDAY/WEDNESDAY.
