Area forecast discussion, Nov 30, 3:50 PM EST, 1 hour 52 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 350 PM EST TUE NOV 30 2010 .SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/... A VERY BUSY DAY TO SAY THE LEAST. THE MAIN SQUALL LINE STRETCHES FROM DAHLONEGA THROUGH DECATUR AND GREENVILLE TO COLUMBUS AT THIS TIME. WARM AIR ADVECTION WITH TEMPS IN THE 70S AND 80S CONTINUE IN ADVANCE OF THE LINE. THE DIURNAL HEATING WILL BE PEAKING SOON WITH MAXIMUM INSTABILITY OVER EAST AND SOUTH GA. HELICITY REMAINS IN THE 300 TO 400 RANGE. CONSEQUENTLY, ANOTHER TORNADO WATCH HAS BEEN ISSUED OVER THE FFC FORECAST AREA FROM ATL TO AGS SOUTHWARD. EXPECT TO BE DROPPING WESTERN COUNTIES FROM THE WATCH EACH HOUR AS THE SQUALL LINE MOVES TO THE EAST. BASED ON CURRENT MOVEMENT, THE ATL METRO AREA SHOULD BE OUT OF THE WATCH BY 500 PM EST. THE WORDING IN THE ZONES REFLECT THIS, BUT HAVE TO KEEP THE HEADLINE FOR THE TORNADO WATCH FOR A LITTLE WHILE LONGER. OTHERWISE, THE COLD FRONT EXTENDS FROM NEAR BLUE RIDGE TO CARTERSVILLE TO CARROLLTON AT THIS TIME. THE FRONT WILL MOVE EAST THROUGH THE FORECAST AREA TONIGHT. A RAPID CHANGE WITH A COLD AIRMASS WILL TAKE PLACE BEHIND THE FRONT AS HIGH PRESSURE BUILDS OVER GA. A NORTHWEST WIND WILL PREVAIL WITH TEMPS DROPPING INTO THE 30S AND 40S BY WEDNESDAY MORNING. CLEAR AND UNSEASONABLY COLD ON WEDNESDAY AND THURSDAY WITH TEMPS 5 TO 10 DEGREES BELOW NORMAL. .LONG TERM /FRIDAY THROUGH TUESDAY/... SIGNIFICANT DIFFERENCES BETWEEN THE 00Z RUN OF THE GFS AND THE 12Z RUN OF THE ECMWF. WE HAVE BEEN LEANING WITH THE GFS AND WILL CONTINUE TO DO SO. THE H5 TROUGH WITH THE CURRENT SYSTEM WILL MOVE OFF THE ATLANTIC WITH A RIDGE BUILDING OVER THE MIDWEST. THIS WILL PUT THE CWA IN A DRY NORTHWEST FLOW THAT WILL CONTINUE THROUGH THE WEEKEND. THIS WILL ALSO KEEP TEMPS AT OR JUST A FEW DEGREES BELOW NORMAL. A SHORT WAVE MOVING THROUGH NORTHWEST CANADA WILL DIVE INTO THE NORTHERN PLAINS AND JOIN WITH AN UPPER LOW OVER NEWFOUNDLAND CANADA AND THEN DEEPEN OVER THE EASTERN U.S. THIS WILL BRING ANOTHER COLD FRONT INTO THE CWA MONDAY NIGHT AND TUESDAY. ATMOSPHERE WILL REMAIN VERY DRY AND AT THIS TIME THE PROBABILITIES ARE TOO LOW TO MENTION PRECIP AT THIS TIME. && .HYDROLOGY... AROUND 2 TO 3 INCHES OF RAIN HAS FALLEN SO FAR IN THE EXTREME NORTHERN COUNTIES OF GA. MOST CREEKS HAVE HAD SIGNIFICANT RISES, BUT NO FLOODING IS EXPECTED TO OCCUR. A FEW MAY REACH BANKFULL BEFORE FALLING THIS EVENING. BIG CREEK NEAR ALPHARETTA WILL BE MONITORED FOR ADDITIONAL RISES AS WELL SINCE AROUND 1.5 INCHES OF RAIN HAS FALLEN ACROSS THAT BASIN. 16 && AVIATION... 18Z UPDATE... MVFR CIGS BUT LINE OF +TSRA APPROACHING THE WESTERN TAF SITES. WILL SEE REDUCED VSBYS WITH THIS LINE AND G30-35KTS. SUSTAINED WINDS WILL REMAIN UP THROUGH THE NIGHT...BUT NOT AS CONFIDENT ON THE WIND GUSTS AT ALL THE TAF SITES OVERNIGHT...BESIDES ATL. WINDS ARE S...BUT GENERALLY EXPECT THE WIND DIRECTION TO BE SSW BECOMING NW LATER THIS AFTERNOON. BEHIND THE LINE OF STORMS...CIGS VARY BETWEEN IFR AND MVFR SO HAVE DECIDED TO SHOW MVFR CIGS WITH SCT007 BUT COULD SEE AN IFR OB.
