Area forecast discussion, Jun 19, 7:43 PM CDT, 1 hour 18 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 743 PM CDT TUE JUN 19 2007 .AVIATION... ONGOING STRONG TO SEVERE CONVECTION WILL AFFECT THE AMARILLO AND DALHART TAF SITES THIS EVENING AND TONIGHT. THUNDERSTORMS OVER SOUTHWEST KANSAS WILL PUSH SOUTH AND SOUTHWEST AND SHOULD AFFECT THE GUYMON TAF SITE LATER THIS EVENING AND OVERNIGHT. LOW CLOUDS AND FOG ARE EXPECTED TO REDEVELOP ONCE AGAIN LATER TONIGHT AND EARLY WEDNESDAY ACROSS THE PANHANDLES CAUSING IFR TO MVFR CEILINGS AND VISIBILITIES. VFR CONDITIONS WILL PREVAIL BY LATE TUESDAY MORNING THROUGH THE AFTERNOON. EAST TO SOUTHEAST WINDS OF 5 TO 15 KNOTS THIS EVENING WILL BECOME SOUTH AND SOUTHWEST 10 TO 20 KNOTS TUESDAY. SCHNEIDER && .PREV DISCUSSION... /ISSUED 719 PM CDT TUE JUN 19 2007/ UPDATE... WITH THE SEVERE WEATHER ONGOING...QUICKLY UPDATED ZFP TO REMOVE EVENING WORDING AND INCREASE POP CHANCES. COULD STILL SEE THE STORMS LINGER INTO THE LATE NIGHT AND EARLY MORNING TIME FRAME. JJB PREV DISCUSSION... /ISSUED 534 PM CDT TUE JUN 19 2007/ UPDATE... UPDATED FORECAST TO ACCOUNT FOR THE SEVERE THUNDERSTORM WATCH. THE WATCH WILL BE IN EFFECT THROUGH 2 AM WEDNESDAY. THERE IS SOME POTENTIAL FOR THE STORMS IN KANSAS TO DEVELOP INTO AN MCS AND MOVE SOUTH INTO THE PANHANDLES LATE TONIGHT. JJB PREV DISCUSSION... /ISSUED 311 PM CDT TUE JUN 19 2007/ DISCUSSION... 19Z AMA SOUNDING THIS AFTERNOON SHOWS LOTS OF CONVECTIVE POTENTIAL IF THE CAP CAN BE BROKEN. SOME CONVECTION IS TRYING TO GO IN SOUTHEAST COLORADO AND NORTHEAST NEW MEXICO WHERE A SURFACE TROUGH IS HELPING TO FOCUS SOME VERTICAL MOTIONS. THE BEST CHANCE OF THUNDERSTORMS THROUGH TONIGHT...WHERE THE CAP WILL BE THE WEAKEST...WILL BE ACROSS THE NORTHERN AND EASTERN CWA. LARGE HAIL AND DAMAGING WINDS WILL BE BE THE MAIN THREATS WITH THESE STORMS. HOWEVER...A TORNADO CAN NOT BE RULED OUT GIVEN THE AMOUNT OF CAPE AVAILABLE AND THE DIRECTIONAL SHEAR AT HAND. THUNDERSTORMS WILL NOT BE OUT OF THE QUESTION...MAINLY ACROSS THE NORTHWEST SECTIONS OF THE PANHANDLES...THROUGH THE END OF THIS WEEK. HOWEVER...WITH UPPER LEVEL RIDGE ONLY BUILDING WITH TIME... BELIEVE THE WARM MID LEVEL TEMPERATURES WILL KEEP THUNDERSTORMS AT BAY...SO WILL NOT INSERT THUNDERSTORMS IN THE FORECAST BEYOND TONIGHT. MAINLY KEPT WITH THE MEX NUMBERS FOR HIGHS AND LOWS AS THEY HAVE COOLED A LITTLE OVER THE LAST FEW RUNS. SO CONFIDENCE IN THESE NUMBERS HAS INCREASED GIVEN THE LATEST SYNOPTIC SITUATION. AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. && .AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. && 11
