Concern...gusty Crosswinds Wednesday before afternoon frontal passage. 


Vigorous low level jet will result in 50-knots winds as low as 1kft above ground level. Have 
introduced low level wind shear through mid-morning. Significant westerly 
component of low level jet should keep stratus east of metropolitan taf sites... 
though Waco will likely see broken MVFR deck. A few hours of gusty 
Crosswinds (18g28kt) with prefrontal veering and downward mixing 
of westerly momentum. Front will arrive middle-afternoon metropolitan... 
shortly thereafter at Waco.

Update... 
quick update for minor temperature and cloud tweaks. Areas in the 
south and east that are still windy are cooling off slower than 
expected. Will have the update out shortly. 84

Previous discussion... /issued 251 PM CST Tuesday Dec 2 2008/ 
as expected...breezy conditions and a dry airmass have resulted in 
red flag criteria being met over much of North Texas this 
afternoon. Gustiness will subside some after dark...but wind 
speeds will remain in the 10 to 20kt range overnight. 


Another breezy day on tap for Wednesday as southwest winds 
gradually shift to westerly during the day ahead of approaching 
front. Cold front should pass through North Texas during the 
afternoon/evening hours. An isolated shower or two will be 
possible along the Red River and across our eastern zones as the 
front translates the region. 


Expect dry weather for the late work week and weekend. Another 
front will push into the area early next week. Models continue to 
display disagreements on strength of front and amount of precipitation. 
Will continue to monitor trends...but for now have backed off on 
cold air and will keep probability of precipitation at slight chance.
