Area forecast discussion, Dec 20, 3:01 PM CST, 42 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HUNTSVILLE AL 301 PM CST THU DEC 20 2007 .DISCUSSION...A PROGRESSIVE PATTERN CONTINUES ACROSS NORTH AMERICA. A SHORTWAVE TROUGH IS CURRENTLY OVER THE TN VALLEY. MOST OF THE PRECIP ASSOCIATED WITH THIS WAVE IS ALONG THE COAST...PRECLUDING MOST OF THE EXPECTED PRECIP FROM FORMING OVER NORTHERN ALABAMA. A LONGWAVE TROUGH CURRENTLY COMING ONSHORE IN NORTHERN CA WILL BEGIN MOVING EASTWARD BECOMING THE MAIN FOCUS OF PRECIP INTEREST ON SATURDAY/SUNDAY MORNING OVER THE TN VALLEY. A SERIES OF SHORTWAVES WILL AFFECT THE REGION OVER THE COMING WEEK. THE ECMWF SEEMS TO BE MORE CONSISTENT WITH THE SHORTWAVES THAN THE GFS. FOR TONIGHT THROUGH SATURDAY...THE FIRST SHORTWAVE CURRENTLY OVER THE SOUTHEAST WILL EXIT THE TN VALLEY LATE TONIGHT. THE PRECIP WILL COMPLETELY EXIT THE REGION BY EARLY TOMORROW MORNING. DUE TO THE WARM CORE CHARACTERISTICS OF THIS SYSTEM...TEMPERATURES WILL NOT CHANGE MUCH. IN FACT WITH CLEARING SKIES...SOUTHERLY FLOW...AND INCREASED WAA TOMORROW...DAYTIME TEMPERATURES SHOULD WARM INTO THE LOW 60S FRIDAY AND SATURDAY. NIGHTTIME FOG COULD BE A CONCERN IN LOW VALLEYS...BUT HAVE NOT INCLUDED IT IN GRIDS AT THIS TIME. CLOUDS WILL BEGIN INCREASING BY SATURDAY MORNING. FOR SATURDAY NIGHT THROUGH SUNDAY...THE SECOND SHORTWAVE IS EXPECTED TO CROSS THE TN VALLEY ON SATURDAY AFTERNOON/EVENING. LOOKING AT BUFR SOUNDINGS...HAVE CONCLUDED THAT PROFILES ARE CURRENTLY TOO WARM ALOFT TO SUPPORT THUNDERSTORMS. SHEAR DOES LOOK IMPRESSIVE...BUT WITHOUT MUCH IN THE WAY OF INSTABILITY...STRATIFORM PRECIP LOOKS MORE VIABLE. WINDS WILL INCREASE SIGNIFICANTLY SATURDAY NIGHT/EARLY SUNDAY MORNING AS THE FRONT APPROACHES WITH DAYTIME HIGH TEMPS SUNDAY EXPECTED IN THE 40S. FOR MONDAY THROUGH WEDNESDAY...AFTER A COLD START ON MONDAY MORNING WITH TEMPS EXPECTED TO BE BELOW FREEZING AT MOST LOCATIONS...A THIRD SHORTWAVE IS EXPECTED LATE MONDAY NIGHT. HOWEVER GIVEN THE ECMWF CURRENT TRACK/DEPICTION...MOISTURE IS LACKING FOR MUCH PRECIP. ALSO...TEMPS ARE NOT EXPECTED TO BE BELOW FREEZING AND TEMPS ALOFT ARE TOO WARM TO SUPPORT DENDRITIC GROWTH. HAVE THUS LEFT A SLIGHT CHANCE OF RAIN IN THE FORECAST FOR MONDAY AND TUESDAY MORNING. AFTER CLOUDS CLEAR BRIEFLY ON WEDNESDAY...TEMPS WILL RECOVER INTO THE 50S. FOR WEDNESDAY NIGHT AND THURSDAY...A FOURTH SHORTWAVE IS THEN EXPECTED TO IMPACT THE REGION ON WEDNESDAY NIGHT/THURSDAY. THE CURRENT RUN SHOWS IT LIFTING NE ACROSS MO/KS. THE EXACT TIMING AND PRECIP IS UNCERTAIN AT THIS POINT...SO HAVE INCLUDED SLIGHT CHANCE POPS DURING THAT TIME PERIOD. TEMPS WILL REMAIN NORMAL FOR THIS TIME OF YEAR BY WEDNESDAY/THURSDAY. && .PRELIMINARY POINT TEMPS/POPS...
