Area forecast discussion 
National Weather Service Brownsville Texas 
736 PM CST Tuesday Dec 2 2008 


Discussion...weak cold front will pass through deep south Texas 
late Wednesday night or early Thursday morning...with another weak 
cold front suggested by GFS to arrive next Tuesday...and tranquil 
conditions in between. Real story through the next seven days will 
be strong southerly winds tomorrow...developing in the morning 
hours and persisting through the afternoon. Wind Advisory a very 
real possibility for Wednesday...with mav guidance indicating 25 
to 35 miles per hour from the south with higher gusts. Think Wind Advisory 
would encompass the five eastern counties of the bro County warning forecast area...but 
will defer issuance of product...if deemed necessary...to shift 
arriving tonight.

Marine...south winds have increased to 20 to 25 knots over the 
Laguna Madre. A Small Craft Advisory has been posted for the Laguna 
Madre through 7 PM CST tonight. The combination of deepening surface 
low pressure over the Texas Panhandle interacting with strong 
surface high pressure over the Gulf will induce strong southerly 
winds over the marine areas by daybreak Wednesday and lasting 
through the day. Small craft advisories will be posted by later 
tonight for all marine areas of deep south Texas Wednesday. A cold 
front will move through the coastal waters of deep south Texas on

flags raised for much of Thursday.
