COLD FRONT AND ASSOCIATED SQUALL LINE EXTENDING FROM JUST WEST OF
HUNTSVILLE TO NEEDVILLE TO WHARTON MOVING RAPIDLY EAST AT AROUND 35
MPH. BY DAYBREAK FRONTAL BOUNDARY SHOULD BE JUST ABOUT EAST OF OUR

BEHIND FRONT WILL RESULT IN WINDY CONDITIONS FOR OUR CWFA TODAY.
WIND ADVISORY WILL REMAIN IN EFFECT UNTIL 6 PM CST. COASTAL ZONES
MAY STILL NEED AN ADVISORY DURING EARLY EVENING HOURS. THIS WILL
BE MONITORED CLOSELY. ELEVATED SHOWERS ASSOCIATED WITH UPPER LOW 
INDICATED TO LINGER OVER THE NORTHERN ZONES THIS AFTERNOON BY WRF
AND GFS. IT WILL BE QUITE COLD TONIGHT WITH TEMPERATURES DROPPING
TO THE MID 20S FAR NORTHEAST ZONES AND UPPER 20S TO MID 30S
ELSEWHERE. FRIDAY AND THE WEEKEND WILL CONTINUE TO BE UNSEASONABLY
COOL. HIGH PRESSURE WILL MAINTAIN DRY WEATHER. HOWEVER THE COASTAL
WATERS AND PERHAPS THE COASTAL ZONES MAY SEE A SLIGHT CHANCE PRECIP
DUE TO A WEAK SURFACE TROUGH DEVELOPING SOUTH OF OUR CWFA.
DEVELOPING UPPER LOW/TROUGH OVER SW CONUS EARLY NEXT WEEK WILL
APPROACH TEXAS BEFORE MID WEEK. SURFACE TROUGH INDICATED TO

RAIN. 37
