Area forecast discussion, May 16, 5:25 PM CST, 1 hour 50 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AMARILLO TX 625 PM CDT SUN MAY 16 2010 .UPDATE... RECENT RADAR TRENDS INDICATE SHOWERS AND THUNDERSTORMS DEVELOPING ACROSS THE SURFACE TROUGH WHICH REMAINS JUST NORTH OF THE AMA CWA LINE. IN ADDITION...A SECOND AREA OF SHOWERS CONTINUE MOVE INTO THE NORTHWEST TX PANHANDLE. THEREFORE...UPDATING POPS TO REFLECT THESE TRENDS. && .AVIATION... FOR THE 00Z TAFS...TSRA MAY AFFECT KDHT OVER THE NEXT 2 HOURS WITH VRB AND GUSTY WINDS. CONVECTION IS NOT EXPECTED TO IMPACT KAMA AND KGUY WITHIN THE FIRST 6 HOURS. FOR TONIGHT...THOUGH THE GFS LAMP IS SHOWING VFR CONDITIONS THROUGH THE TAF PERIOD...LIGHT NORTHEASTERLY WINDS AND STILL WET GROUND NEAR THE TERMINALS SHOULD PROMOTE BR OR LOW STRATUS DEVELOPMENT AFTER 06Z. HAVE KEPT CONDITIONS MVFR FOR NOW DUE TO THE FACT THAT THERE IS NOT ANY SUPPORT FROM THE MODELS...WITH THE EXCEPTION OF THE NAM...THOUGH WOULD NOT BE SUPRISED IF THERE ARE LOCALIZED IFR AND EVEN LIFR CONDITIONS ESPECIALLY BETWEEN 10 AND 14Z. CHANCES FOR TSRA INCREASE AFTER 18Z...THOUGH STILL NOT ENOUGH CERTAINTY TO INCLUDE IN THE TAFS. SJOHNSON && .PREV DISCUSSION... /ISSUED 304 PM CDT SUN MAY 16 2010/ DISCUSSION... THE SURFACE TROF HAS CLEARED ALL BUT THE SOUTHEAST CORNER OF THE TX PANHANDLE AND CONTINUES TO MAKE SLOW BUT STEADY PROGRESS TO THE SOUTH. SCATTERED STRONG THUNDERSTORMS HAVE DEVELOPED IN THE VICINITY OF THIS BOUNDARY WHICH WILL BE THE MAIN FOCUS THROUGH THIS EVENING. A FEW OF THESE STORMS COULD BRIEFLY BECOME SEVERE THROUGH THIS EVENING. WE COULD ALSO SEE THE ISOLATED CONVECTION DEVELOPING OVER NORTHEAST NM DRIFT INTO THE NORTHWEST ZONES. THEREFORE...POPS WILL BE CONFINED TO THE SOUTH CENTRAL AND SOUTHEAST TX PANHANDLE AS WELL AS THE EXTREME NORTHWEST COUNTIES THROUGH TONIGHT. A WARM ADVECTION PATTERN WILL SET UP TONIGHT AS SOUTHERLY FLOW DEVELOPS ABOVE THE BOUNDARY LAYER. THIS SHOULD AID IN THE DEVELOPMENT OF LOW CLOUDS AND MAY ONCE AGAIN PROMOTE PATCHY DRIZZLE...ESPECIALLY ACROSS THE WESTERN COUNTIES. HOWEVER...NO MEASURABLE PRECIP IS ANTICIPATED THROUGH 12Z. THIS BOUNDARY IS FORECAST TO LIFT BACK TO THE NORTH ON MONDAY AS PRESSURE FALLS TO OUR NORTH AND WEST TIGHTEN THE SURFACE GRADIENT. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG THIS RETREATING BOUNDARY. THERE IS STILL SOME DOUBT AS TO HOW LONG IT WILL TAKE TO ERODE ANY LOW CIGS BUT WITH ANY DECENT AMOUNT OF INSOLATION WE SHOULD BE ABLE TO TAP INTO THE INSTABILITY ALOFT. WIND PROFILES SUGGEST THAT SHEAR WILL BE SUFFICIENT FOR ORGANIZED CONVECTION RESULTING IN A SMALL THREAT OF SEVERE THUNDERSTORMS. THE LOW LEVEL JET INTENSIFICATION SHOULD MAINTAIN CONVECTION FOR A GOOD PORTION OF THE NIGHT. SEE SWODY2 FOR ADDITIONAL DETAILS. BY TUESDAY...A POTENT SHORTWAVE TROF IS PROGGED TO BE MOVING ACROSS THE GREAT BASIN...WITH A LEAD SHORTWAVE EXPECTED BY PEAK HEATING ON TUESDAY. THE ASCENT ASSOCIATED WITH THIS FEATURE WILL HELP COOL TEMPS ALOFT. IN ADDITION...A FAVORABLY POSITIONED H25 JET WILL PROVIDE ENHANCED VERTICAL MOTION ACROSS THE CWA. THE MAIN FORECASTING ISSUE IS WHERE THE SURFACE TROF WILL SET UP. SEVERAL MODEL SUITES HAVE DEVELOPED A SURFACE LOW OVER EASTERN NM WITH STRONG UPSLOPE FLOW ACROSS MUCH OF THE AREA WITH A SURFACE TROF EXTENDING ACROSS THE SOUTHWEST ZONES. THIS COULD BE THE MAIN AREA OF CONCERN FOR THE SEVERE WEATHER POTENTIAL. I THINK THE SPC DAY 3 OUTLOOK IS A GOOD STARTING POINT FOR LOCATION BUT STRONG SHEAR AND INSTABILITY PROGS SUGGEST THAT THE THREAT MAY ALSO EXIST FARTHER DOWNSTREAM. THE MAIN CAVEAT WILL CONTINUE TO BE THE POTENTIAL FOR MORNING GRUNGE CUTTING INTO THE SURFACE BASED INSTABILITY. A SIMILAR SETUP IS ANTICIPATED FOR WEDNESDAY WITH A SURFACE TROF SETTING UP OVER THE EASTERN ZONES. THE GFS IS QUITE A BIT FASTER WITH THE UPPER FORCING COMPARED TO YESTERDAY/S RUN /AND ALSO FARTHER NORTH/ WHILE THE ECMWF/NAM REMAIN MORE CONSISTENT. WILL IGNORE THE 12Z GFS KEEPING HIGH POPS AND MAINTAINING THE SEVERE POTENTIAL FOR WEDNESDAY AS WELL. TEMPS WERE KEPT VERY NEAR THE 00Z MEX GUIDANCE FOR MIDWEEK. THE COLD FRONT WILL LIKELY TRAVERSE THE PANHANDLES WEDNESDAY NIGHT RESULTING IN COOLER CONDITIONS FOR THURSDAYS. I WILL MAINTAIN THE LOW POPS FOR NOW IN THE EAST ON THURSDAY DESPITE MY GUT SAYING TO TAKE THEM OUT. SHORTWAVE RIDGING FOR THURSDAY NIGHT QUICKLY GIVES WAY TO INCREASING SOUTHWEST FLOW ALOFT BY LATE FRIDAY WITH STRONG LEE CYCLOGENESIS UNDERWAY BY THE AFTERNOON HOURS. THE RESULT WILL BE MUCH STRONG WINDS FRIDAY/SATURDAY WITH WARMER TEMPS. HIGHS ARE PROGGED TO CLIMB INTO THE 80S ON FRIDAY AND APPROACH 90 DEGREES IN SOME AREAS BY SATURDAY. A VERY DEEP TROF IS PROGGED TO OVERTAKE THE WESTERN CONUS BY THIS TIME WHICH WILL ENHANCE OUR THUNDERSTORM CHANCES ALONG THE SURFACE TROF/DRYLINE BY SATURDAY AFTERNOON. I HAVE INSERTED LOW POPS MAINLY ACROSS THE EAST. BEYOND SATURDAY...THE MODELS DIFFER ON THE BEHAVIOR OF THIS LONGWAVE TROF. THE GFS/DGEX BLAST A COLD FRONT THROUGH THE AREA BY SUNDAY WHILE SLOWER ECMWF KEEPS STRONG SOUTHERLY WINDS...WARM TEMPS AND DIURNAL CONVECTION IN THE FORECAST. I WENT MORE WITH A COMPROMISE OF THE 00Z GFS ENSEMBLE FOR NOW...KEEPING THE BOUNDARY TO THE NORTH OF THE AREA THROUGH SUNDAY. JOHNSON FIRE WEATHER... NO FIRE WEATHER CONCERNS ARE ANTICIPATED THROUGH THURSDAY ACROSS THE TX/OK PANHANDLES. BY FRI/SAT WINDS WILL INCREASE AS LEE TROFFING RESUMES. HOWEVER...GIVEN RECENT RAINFALL AND THE POTENTIAL FOR MORE PRECIPITATION...NO MENTION OF ELEVATED FIRE WEATHER CONDITIONS WILL BE MADE OUTSIDE OF THIS DISCUSSION FOR NOW. JOHNSON && .AMA WATCHES/WARNINGS/ADVISORIES... TX...NONE. OK...NONE. && 16/01
