AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
827 PM CDT SUN OCT 19 2014

.UPDATE...
TO ADJUST SKY COVER UPWARD FOR MID AND HIGH CLOUDS PER SATELLITE AND
OBSERVATION TRENDS.

.DISCUSSION...
A BAND OF MID AND HIGH CLOUDS WAS MOVING EASTWARD THRU THE REGION
THIS EVENING. THE CLOUDS WERE MOST PREVALENT ACROSS TN AND THE NERN
PORTIONS OF AL. WE HAVE ADJUSTED SKY COVER TO BETTER ACCOUNT FOR
THIS, BUT FULLY EXPECT IT TO BEGIN EXITING AROUND OR AFTER 06Z.
DESPITE THE CLOUDS, TEMPS IN SRN TN HAVE DIPPED INTO THE U40S, WITH
L-M50S IN NRN AL EXCEPT FOR THE HSV AREA. THE URBAN HEAT ISLAND IS
KEEPING THE TEMP AT 59F AS OF THE TOP OF THE HOUR. THE BUFKIT FOG
TOOLS INDICATE FAVORABLE RADIATION FOG CONDITIONS, PARTICULARLY IN
OUR NOTORIOUS VALLEY LOCATIONS. THIS ALONG WITH THE SFC RIDGE AXIS
NOW LOCATED FROM OHIO THRU LOUISIANA SHIFTING THRU THE REGION AS
WELL. GOOD DRYING CONDITIONS THE PAST COUPLE OF DAYS SHOULD PREVENT
WIDESPREAD DENSE FOG DEVELOPMENT THOUGH. NO OTHER SIGNIFICANT CHANGES
TO THE FORECAST WERE NEEDED.
