WIDESPREAD CONVECTION ALONG THE QUASI STATIONARY SURFACE TROF WILL WREAK HAVOC WITH THE KAMA TAF THROUGH THE EVENING HOURS. A TEMPO INCLUDING TSRA WITH GUSTY WINDS AND MVFR CIGS/VSBY WAS INCLUDED IN THE INITIAL HOUR GIVING WAY TO SHOWERS AND VCTS FOR AN HOUR OR TWO THEREAFTER. FARTHER NORTH...A CB WAS INCLUDED AT KDHT GIVEN THE PROXIMITY TO THE STORM 30 MILES TO THE SOUTH BUT KGUY SHOULD BE FAR ENOUGH REMOVED TO KEEP MENTION OUT OF THE TAF. OVERNIGHT...MID/HIGH LEVEL CONVECTIVE DEBRIS ARE EXPECTED WITH PREVAILING VFR CONDITIONS.

CONVECTION CHANCES THROUGH THE SHORT TERM PART OF THE FORECAST WILL BE THE MAIN FORECAST CONCERNS. SURFACE TROUGH HAS DIPPED INTO THE NORTHERN PANHANDLES AS OF DISCUSSION TIME. ACROSS THE SOUTHERN AND SOUTHEASTERN TEXAS PANHANDLE...DEWPOINTS ARE RUNNING IN THE MIDDLE TO UPPER 60S. THIS COUPLED WITH TEMPS AOA 90 DEGREES HAS YIELD ATMOSPHERE TO BECOME QUITE UNSTABLE WITH SBCAPES AROUND 4000 J/KG. LATEST GUIDANCE SUGGESTS THUNDERSTORMS DEVELOPING ACROSS THE SOUTHERN TX PANHANDLE LATE THIS AFTERNOON AND EVENING AND GIVEN DEGREE OF INSTABILITY...A FEW STRONG TO SEVERE THUNDERSTORMS MAY BE POSSIBLE. OTHERWISE... UPPER LEVEL FLOW REMAINS OUT OF THE W TO NW INTO NIGHT. HELD ON TO THE POPS ACROSS THE NORTHERN ZONES AS MOUNTAIN CONVECTION MAY BE ABLE TO DRIFT INTO THE AREA. FORECAST FOR MONDAY MAY BECOME A LITTLE MORE TRICKY DEPENDING ON WHERE THE BOUNDARY ENDS UP. OVERNIGHT CONVECTIVE COMPLEXES COULD AID IN PUSHING THE FRONT A BIT FURTHER SOUTH INTO THE PANHANDLES...AND THIS WILL PLAY A ROLE IN CONVECTIVE COVERAGE TOMORROW. DECIDED TO THE HOLD ON TO THE SLIGHT END POPS ACROSS THE AREA DURING THE DAYTIME...AND THEN STARTED TO TRIM BACK POPS FROM THE NORTHWEST FOR MONDAY NIGHT AS UPPER LEVEL SHORTWAVE TROUGH SWINGS THROUGH. UPPER LEVEL RIDGE WILL SET UP ACROSS THE PANHANDLES TUESDAY INTO WEDNESDAY ACROSS THE SOUTHERN PLAINS. THIS WILL BRING ABOUT DECREASING PRECIP CHANCES ALONG WITH TEMPS ABOVE NORMAL FOR THIS TIME OF YEAR. MIDDLE TO UPPER 90S WITH A FEW 100/S MIXED IN SEEM REASONABLE FOR THE MIDDLE PART OF THE WEEK. LATEST GUIDANCE IN PRETTY GOOD AGREEMENT ON THIS SCENARIO AND MAV/MEX NUMBERS WERE GENERALLY ACCEPTED. UPPER LEVEL TROUGH LOOKS TO MOVE ACROSS THE NORTHERN PLAIN STATES WEDNESDAY/THURSDAY...WITH BOUNDARY APPROACHING THE AREA. SLIGHT END POPS WERE RETAINED FOR THURSDAY ACROSS THE NORTH AND AREA WIDE ON THURSDAY NIGHT. UPPER RIDGE SHOULD REMAIN THE PREDOMINANT FEATURE DURING THE EXTENDED PART OF THE FORECAST. HOWEVER...WHERE THE CENTER OF THE RIDGE SETS UP STILL REMAINS A BIT MORE UNCERTAIN. ANY WEAKNESS IN THE RIDGE COULD YIELD A FEW STORMS DURING THE EXTENDED...BUT WILL KEEP STATUS QUO IN THE GRIDS FOR NOW. FIRE WEATHER... NO FIRE WEATHER CONCERNS ANTICIPATED THROUGH THE FORECAST DUE TO RECENT RAINFALLS AND CONTINUED CHANCES OF SHOWERS AND STORMS. && .AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. && 24/03
