.DISCUSSION...
/ISSUED 932 PM CDT SUN SEP 21 2014/
SFC OBSERVATIONS AT 9 PM CDT INDICATE A COOLER/DRIER CP AIRMASS
POISED JUST TO OUR NORTH...READY TO ENTER THE AREA. WINDS HAVE
SHIFTED TO NORTHERLY AT MOST LOCATIONS NORTH OF THE TN
RIVER, ALTHOUGH THE STRONGER DEW POINT GRADIENT LINGERS BEHIND THE
WIND SHIFT BY ABOUT 100 MILES. AT THE LEADING EDGE OF THE COMPLEX
FRONTAL BOUNDARY ALONG THE LOW-LVL CONVERGENCE AXIS, A FEW SHOWERS
AND STORMS CONTINUE TO DEVELOP AND PUSH SEWRD. CURRENTLY, THE
STRONGEST STORM IN OUR AREA IS IN EASTERN PORTIONS OF CULLMAN COUNTY.
OTHER SMALL, ISOLD SHOWERS LIE TO THE NE FROM NEAR ALBERTVILLE TO
VALLEY HEAD. MOST OF THE SHOWER/STORM ACTIVITY WILL LIKELY EXIT THE
AREA BY 03Z. HOWEVER, A SLIGHT CHANCE SHOWER/STORM MENTION WAS
INCLUDED ALONG A VERY NARROW SLIVER OF OUR FCST AREA FROM EASTERN
CULLMAN TO SOUTHERN MARSHALL AND EASTERN DEKALB DUE TO THE POTENTIAL
FOR LINGERING SMALL POCKETS OF LOW-LVL WIND CONVERGENCE. SKY
CONDITIONS WILL RAPIDLY CLEAR TONIGHT AS THE DRIER AIRMASS MOVES INTO
THE AREA. GENERALLY MINOR TEMP/DEW POINT ADJUSTMENTS WERE MADE TO THE
FORECAST. LOWS TONIGHT EXPECTED TO RANGE FROM THE MID 50S IN THE
NORTH TO THE LOW 60S IN FAR SOUTHERN PORTIONS OF THE AREA.
