Area forecast discussion, May 17, 3:37 AM CST, 1 hour 13 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 437 AM CDT MON MAY 17 2010 .DISCUSSION... CHANCES FOR CONVECTION WITH THE POTENTIAL FOR SEVERE THUNDERSTORMS TODAY THROUGH WEDNESDAY WILL BE THE MAIN FORECAST CONCERNS THIS MORNING. SHOWERS AND THUNDERSTORMS HAVE ALL READY DEVELOPED THIS MORNING WITH AID OF THE LOW LEVEL JET. EXPECT THIS CONVECTION TO CONTINUE TO MOVE SOUTHEASTWARD ACROSS THE PANHANDLES THROUGHOUT THE MORNING AND HAVE ACCOUNTED FOR THIS IN THE LATEST GRIDS. OTHERWISE...LOW LEVEL FLOW WILL BECOME MORE SOUTHEASTERLY UPSLOPE AS THE DAY PROGRESSES. GIVEN RELATIVELY MOIST ATMOSPHERE IN PLACE ACROSS THE PANHANDLES...EXPECT ADDITIONAL SHOWERS AND THUNDERSTORMS TO DEVELOP AGAIN LATE THIS AFTERNOON INTO THE EVENING HOURS. WOULD NOT BE SURPRISED TO SEE SOME STRONG TO POSSIBLY SEVERE THUNDERSTORMS AS SUFFICIENT SHEAR WILL BE COUPLED WITH INCREASING INSTABILITY. CHANCES FOR THUNDERSTORMS WILL CONTINUE INTO THE EVENING AND OVERNIGHT HOURS AS LOW LEVEL JET DEVELOPS. UPPER LEVEL FLOW WILL BECOME MORE SOUTHWESTERLY HEADING INTO TUESDAY IN ADVANCE OF APPROACHING UPPER LEVEL TROUGH. SURFACE TROUGH LOOKS TO SET UP ACROSS SOUTHEASTERN COLORADO AND EASTERN NEW MEXICO BY TUESDAY AFTERNOON. LATEST RUNS OF THE NAM AND GFS IN FAIRLY GOOD AGREEMENT WITH THE DRYLINE PLACEMENT DURING THE AFTERNOON HOURS TUESDAY. BOTH DEPICT THE DRYLINE HANGING AROUND THE NEW MEXICO AND TEXAS STATE LINE...WITH AMPLE MOISTURE DOWNSTREAM. FORECAST PWAT VALUES ARE BETWEEN 1.00 AND 1.25 INCHES ACROSS MUCH OF THE AREA COURTESY OF PERSISTENT SOUTHEASTERLY UPSLOPE FLOW. INCREASING DEEP LAYER SHEAR AOA 45 KNOTS AND MODEST INSTABILITY WILL ONCE AGAIN LEAD TO A CHANCE OF STRONG TO SEVERE THUNDERSTORMS. OF CONCERN THOUGH...IF LOW CLOUDS DO DEVELOP DURING THE MORNING HOURS AND ARE TOUGH TO ERODE THIS COULD AFFECT SEVERE POTENTIAL ON TUESDAY. YET MORE THUNDERSTORMS APPEAR IN STORE ON WEDNESDAY AS SURFACE TROUGH AND DRYLINE ARE PUSHED TO THE EAST INTO THE PANHANDLES. HERE IS WHERE SOME DIFFERENCES BEGIN TO CREEP UP...WITH THE NAM HOLDING THE DRYLINE BACK UP A BIT WHILE THE GFS SHOVES IT OUT OF THE EASTERN ZONES BY 00Z THURSDAY AS COLD FRONT MOVES INTO THE REGION. FOR NOW...WILL KEEP THE INHERITED POPS IN TACT AND TAKE A MIDDLE OF THE ROAD APPROACH. ANY SEVERE WEATHER THREAT FOR WEDNESDAY SHOULD SHIFT TO THE EASTERN ZONES BUT WILL COMMENT THAT TUESDAY/S CONVECTION COULD END UP COMPLICATING THE FORECAST FOR WEDNESDAY. ONE CHANGE TO THE FORECAST THIS MORNING WAS TO REMOVE POPS DURING THE THURSDAY TIME FRAME. MEDIUM RANGE GUIDANCE WANTS TO MOVE THE COLD FRONT THROUGH THE PANHANDLES BY 12Z THURSDAY SO FELT COMFORTABLE ENOUGH TO REMOVE THEM. BRIEF UPPER LEVEL RIDGING SETS UP ACROSS THE PANHANDLES LATE THURSDAY NIGHT INTO FRIDAY IN ADVANCE OF THE NEXT STRONG UPPER LEVEL TROUGH. THIS WILL LEAD TO INCREASING SOUTHWEST FLOW FLOW ALOFT AND THE SURFACE TROUGH DEVELOPING BY THE END OF THE WORK WEEK INTO THE WEEKEND...ALONG WITH WARMING TEMPERATURES. GUIDANCE SUGGESTS TEMPERATURES INCREASING INTO THE UPPER 80S AND LOWER 90S BY SATURDAY. INHERITED POPS ACROSS THE EASTERN ZONES ON FOR DRYLINE THUNDERSTORMS ON SATURDAY APPEAR FINE ATTM...WITH WINDS RAMPING UP AS WELL. TAB && .FIRE WEATHER...
