AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
300 AM CDT MON MAY 4 2015

.DISCUSSION...
UNDER CLR SKIES TEMPS WERE MAINLY IN THE MID 50S WITH DEWPOINTS
BETWEEN 45 AND 50 DEGREES. SFC/UPPER HIGH ACROSS THE SERN US WAS
KEEP A CDFNT/CONVECTION ACROSS PORTIONS OF THE MID WEST AND GREAT
LAKES ATTM. WITH HIGH PRESSURE PROGGED TO BE IN PLACE ACROSS MOST OF
THE SERN US FOR THE UPCOMING WORK WEEK...LITTLE TO NO PCPN IS
EXPECTED ACROSS THE TN VALLEY THRU AT LEAST SUNDAY.

HOWEVER MODELS DO SHOW A POSSIBLE TROPICAL SYSTEM/COASTAL LOW THAT
MAY AFFECT PORTIONS OF THE SERN US BY THE END OF THE WEEK. GFS TAKES
THE TROPICAL SYSTEM FURTHER WEST...INTO THE CAROLINAS BY THURSDAY.
ECMWF KEEPS THE SYSTEM FARTHER EAST ALONG THE COASTAL AREAS OF THE
SERN US. ANYWAY YOU CUT IT...IF THIS TROPICAL SYSTEM DOES FORM A
RIDGE WILL LIKELY BUILD ACROSS THE TN VALLEY WHICH SHOULD HELP TO
KEEP MAINLY DRY CONDITIONS INTO THE WEEKEND. FOR NOW WILL LEAN A
LITTLE MORE WITH THE GFS AND KEEP A LOW POP IN FOR SHRA/TSRA ON
SUNDAY.

AS MENTIONED PREVIOUSLY WITH HIGH PRESSURE OVER THE REGION THIS
WORK WEEK...LOOKS LIKE THE DRY CONDITIONS ALONG WITH A WARMING TREND
WILL BE THE MAIN WX STORY FOR THE TN VALLEY. ATTM NEXT WEEKEND WOULD
HAVE THE BEST CHC OF SOME SCT SHRA/TSRA DEPENDING ON THE TRACK OF THE
TROPICAL SYSTEM.
