Area forecast discussion, Jul 28, 3:49 PM CDT, 1 hour 16 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 349 PM CDT FRI JUL 28 2006 .SHORT TERM...(TONIGHT THROUGH MONDAY NIGHT) WHAT A DILEMMA THIS FORECAST HAS BECOME THE NAM AND GFS CONTINUE TO DIFFER GREATLY THROUGH SUNDAY...WITH THE ECMWF AND UKMET FAVORING THE DRYER NAM SOLUTION. THE NAM KEEPS THE SHORTWAVE AND THUS THE BULK OF RAIN TO THE NORTH...WHILE THE GFS BRINGS IT ACROSS CENTRAL ALABAMA SATURDAY AND THEN ANOTHER ONE ON SUNDAY. THE GFS HAS BEEN WAY TO WET THIS LAST WEEK...BUT THE HUGE ISSUE FOR ME IS THE FACT IT IS CURRENTLY RAINING WITH EXCELLENT COVERAGE WEST OF INTESTATE 65 AND NORTH OF INTERSTATE 20. VERY CLOSE TO WHERE THE GFS INDICATED IT TO BE. WILL GO WITH CURRENT RADAR TRENDS FOR TONIGHT/S POPS. FOR TOMORROW WILL NOT HAVE LIKELY EVERYWHERE BUT EXPECT THE BEST RAIN TO BE INTERSTATE 20 AND NORTH. EVEN IF THE NAM SOLUTION WERE 100% CORRECT WITH TEMPS IN THE 90S...CAPES OVER 2000 J/KG...LI/S-4+...AND OUTFLOWS FROM THE NORTH SOMETHING COULD BE SPARKED. THIS IS ALSO A VERY TROPICAL AIRMASS. WILL TAPER POPS TOMORROW FROM LIKELY NORTH TO LOW END CHANCE SOUTH. NOT SURE WHAT TO DO WITH POPS SUNDAY AND MONDAY SO TOOK A MIDDLE OF THE ROAD APPROACH. MODELS INDICATE MONDAY WILL BE THE DRIEST DAY. TEMPERATURES...THE GFS IS A BIT ON THE COOL SIDE SO WENT ABOVE MAV GUIDANCE BUT BELOW MET. EXPECT AFTERNOON HIGHS TO BE IN THE UPPER 80S FOR THE COOLER ELEVATED LOCATIONS TO THE LOWER TO MID 90S FOR THE WARMER SPOTS. OVERNIGHT LOWS WILL BE IN THE LOWER TO MID 70S WITH THE COOLER LOCATIONS IN THE UPPER 60S. 80 .LONG TERM...(TUESDAY THROUGH FRIDAY) DGEX AND GFS BOTH DEVELOP A LOW IN THE WESTERN ATLANTIC OFF THE GA...SC COAST. THE GFS MEANDERS IT WEST AND EVENTUALLY IT GETS CAUGHT UP IN A FRONT PAST DAY 7. THE DGEX MOVES THE LOW NORTH AND EAST. NOT SURE WHAT TO BELIEVE. THE GFS IS MUCH WETTER FOR THE FORECAST AREA. AT THIS TIME WILL NOT MAKE MANY CHANGES TO CURRENT FORECAST. WILL GO WITH SCATTERED POPS FOR DAYTIME AND ISOLATED FOR EVENING. TEMPERATURES SHOULD BE ABOVE CLIMATOLOGY FOR LATE JULY/EARLY AUGUST. 80 && .AVIATION...DISCUSSION FOR 18Z TAFS. STORMS WILL CONTINUE TO DEVELOP ACROSS NORTHWEST ALABAMA. SOME OF THESE STORMS COULD AFFECT TCL AND BHM. WILL CONTINUE TO WATCH THE WEATHER OVER THE NEXT SEVERAL HOURS AND WILL ADJUST THE FORECAST AS NEEDED.
