Area forecast discussion, Jul 28, 3:26 PM EDT, 3 hours 3 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 326 PM EDT FRI JUL 28 2006 .SHORT TERM /TONIGHT THROUGH SATURDAY/... CONVECTION CONTINUES TO FIRE AHEAD OF SURFACE BOUNDARY AND WITH APPROACH OF SHORT WAVE. ACTIVITY WILL WIND DOWN BY LATE EVENING AS UPPER SUPPORT MOVES EAST AND WITH LOSS OF HEATING. PRIMARY PROBLEM WILL BE POTENTIAL FOR STRONG WIND GUSTS AND LOCALIZED DRAINAGE FLOODING. GIVEN HIGH FREEZING LEVELS...HAIL POTENTIAL WILL BE QUITE LIMITED. ON SATURDAY...SCATTERED CONVECTION DEVELOPS BY AFTERNOON AHEAD OF THE FRONT WITH HIGHEST POPS ACROSS THE HIGHER TERRAIN. WESTERLY FLOW SHOULD ALLOW EVEN THE COAST TO BAKE WITH READINGS CLOSE OR EXCEEDING 90 IN MANY LOCATIONS. && .LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/... THE COLD FRONT WILL CROSS THE FORECAST AREA BEFORE MIDNIGHT. FOR NOW...WILL HOLD OFF ON CARRYING A MENTION OF SHOWERS AND THUNDERSTORMS GIVEN THE TIME OF DAY...BUT LATER FORECASTS MAY HAVE TO ADDRESS THIS. AFTER THIS...THERE SHOULD BE A FAIR AMOUNT CLEARING...EXCEPT FOR NEAR THE COAST. WITH THE AIRMASS TRANSITION SLOW...WENT WITH A BLEND OF MOS NUMBERS FOR LOWS SATURDAY NIGHT. MODELS ARE A BIT CLOSER ON THE POSITION OF THE FRONT FOR SUNDAY...BUT STILL ENOUGH DIFFERENCES FOR A PROBLEMATIC FORECAST...ESPECIALLY FOR SOUTHERN NEW HAMPSHIRE. AT THIS POINT...BELIEVE MOST MODELS ARE TOO FAR SOUTH WITH THE FRONT...GIVEN THAT THE PUSH IN THE MID LEVELS SHEARS OUT TO THE EAST AND WEAKENS. BECAUSE OF THIS...BELIEVE THAT SOUTHERN NEW HAMPSHIRE HAS A SHOT OF FIRING CONVECTION ON THE FRONT. ELSEWHERE...EXPECT A QUIETER DAY WITH A FAIR AMOUNT OF CUMULUS. 850 MB TEMPERATURES SUPPORT A BLEND OF MOS NUMBERS FOR HIGHS ON SUNDAY. ANY CONVECTION THAT DEVELOPS SUNDAY SHOULD END WITH DIURNAL HEATING. BELIEVE THE GFS IS TOO COOL WITH THE NEW AIRMASS...SINCE THE TRANSITION SHOULD BE SLOW. LEANED TOWARD THE NAM MOS FOR LOWS SUNDAY NIGHT BECAUSE OF THIS. LOOKING FURTHER AHEAD...MODELS CONTINUE TO HAVE DIFFERENCES ON HOW TO HANDLE THE SHORT WAVE ENERGY IN THE NORTHERN STREAM...AND HOW FAR NORTH THE RIDGING WILL GET. FOR NOW...USED AN APPROACH CLOSER TO THE 06Z/12Z GFS. THIS MEANS THAT JUST ABOUT EVERY DAY THROUGH WEDNESDAY HAS A CHANCE OF SHOWERS AND THUNDERSTORMS WITH THE BOUNDARY CLOSE BY. STUCK CLOSE TO GUIDANCE WITH THE UNCERTAINTY. A MORE SUBSTANTIAL COLD FRONT SHOULD CROSS THE REGION WEDNESDAY EVENING...WITH COOLER CONDITIONS AFTER THIS. && .AVIATION... VFR WITH LOCAL IFR IN THUNDERSTORMS THROUGH EVENING...THEN WIDESPREAD MVFR OVERNIGHT IN FOG AND HAZE. && .MARINE... SHORT TERM (TONIGHT AND SATURDAY)...WINDS AND SEAS MAY APPROACH SMALL CRAFT TONIGHT AHEAD OF SURFACE THROUGH THIS EVENING. OTHERWISE...PRIMARY PROBLEM WILL BE SCATTERED STRONG CONVECTION TONIGHT AND VSBY RESTRICTIONS IN FOG AND HAZE. LONG TERM (SATURDAY NIGHT THROUGH WEDNESDAY)... A FEW WIND GUSTS TO 20 KT ARE POSSIBLE AHEAD OF THE FRONT SATURDAY EVENING. AFTER THIS...BECAUSE OF THE PROXIMITY OF THE FRONT...WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT LEVELS. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...NONE. NH...NONE. MARINE...NONE. &&
