.DISCUSSION...
/ISSUED 1030 AM CDT SUN MAR 29 2015/
SURFACE HIGH PRESSURE IS ANCHORED ALONG THE EASTERN SEABOARD BUT WILL
PROVIDE A PLEASANT DAY ACROSS THE TN VALLEY. TEMPERATURES ROSE
QUICKLY THIS MORNING FROM THE UPPER 20S TO THE UPPER 40S. TEMPS WILL
CONTINUE TO REBOUND BEFORE CLOUD COVER MOVES IN FROM THE SOUTHWEST
BUT WINDS WILL BE FROM THE SOUTHEAST TODAY AROUND 5-10KT TO ASSIST IN
ADDITIONAL WARMING. ADJUSTED CLOUD COVER FOR THE CURRENT TRENDS...AS
THEY ARE SLOW TO MOVE IN SO FAR THIS MORNING. ALSO ADJUSTED THE
HOURLY DEWPOINTS DUE TO THE DRIER AIR IN THE EASTERN PORTION OF THE
CWA THIS MORNING. THEY WILL RISE THROUGHOUT THE DAY AS THE HIGH
MOVES EAST SO ADJUSTED THE HOURLY TREND AS WELL. OTHERWISE THE REST
OF THE FORECAST PACKAGE IS ON TRACK FOR TODAY.

.AVIATION...
FOR 18Z TAFS...2-3KFT CIGS ARE MOVING FROM THE WEST AND SHOULD BE AT
KMSL BY 18Z AND KHSV AT 19Z OR SHORTLY AFTER. ONCE THESE CLOUDS MOVE
OUT...ANOTHER AREA OF LOW-MID CLOUDS WILL MOVE IN FROM THE NW. THERE
IS A CHANCE THERE WILL BE A BREAK IN THE CLOUDS BETWEEN THESE TWO
SYSTEMS AND INCLUDED AN EXTRA GROUP TO BRING CLOUDS UP TO SCT
BRIEFLY. THERE IS LOW CONFIDENCE IN THIS SOLUTION SO AMENDMENTS MAY
BE NEEDED TONIGHT. AN OCCASIONAL GUST OF 15-20KT MAY BE POSSIBLE THIS
AFTERNOON BUT WILL NOT BE FREQUENT ENOUGH TO MENTION IN THE TAFS. A
COLD FRONT WILL MOVE THROUGH IN THE MORNING WITH A QUICK BURST OF
RAIN BETWEEN ABOUT 07-15Z. THERE IS A SLIGHT CHANCE OF THUNDER
TONIGHT AS WELL BUT TOO ISOLATED TO MENTION. CIGS WILL DROP DURING
THIS TIME TO BELOW 2KFT BUT SKIES SHOULD QUICKLY CLEAR AFTER 15Z.
