Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
714 PM CDT Thursday Aug 28 2008 


Update... 
minor tweaks to mainly removed isolated showers/storms as activity near 
Lampasas should continue to wane as we near sunset. Otherwise...tweaked 
sky cover to more clear/mostly clear over partly cloudy and made winds 
more southeast this evening...becoming light/variable overnight. 
Update sent. 


We'll be maintaining a watch on soon-to-be Hurricane Gustav affecting 
Jamaica at this time...entering the Gulf of Mexico this weekend...before taking 
it into the central Louisiana coastline per preliminary hurricane center tracking. 
These storms can be tricky...so many more updates to come on the track 
updates and we keep showing update graphical images on our web-Page next 
several days.

Previous discussion... /issued 642 PM CDT Thursday Aug 28 2008/ 
315 PM 
for much of the next week...North Texas will remain under the 
influence of an upper level ridge. Starting tomorrow...the upper 
level ridge currently over the western Continental U.S. Will begin to 
build across North Texas and will be centered over the Southern 
Plains by tomorrow night. The ridge will keep moving east and 
settle over the eastern Continental U.S. By the end of the weekend. However 
its vast expanse will keep its influence over Texas. The ridge 
will continue to be pushed east by a digging trough across 
the western Continental U.S. But this trough will lift to the northeast and 
stay well north of Texas. Will continue to watch Gustav and the 
position of the upper level ridge over the next few days to 
determine any impacts on North Texas by the middle of next week. 


A cold front which currently extends from the northwest Texas 
Panhandle through central Kansas will not make it into North Texas 
as is but a few showers or storms may work their way across the 
Red River Friday night ahead of the cold front as it slides into 
central Oklahoma. The associated surface high behind the front 
will move into the Midwest this weekend and a weak boundary /or 
possibly the tail end of the front/ will slide into North Texas 
from the east on Saturday morning. The impacts from this 
boundary/front will be minimal but it could bring some isolated to 
scattered showers and storms on Saturday. Will keep 20 probability of precipitation in on 
Saturday. 


Sunday and Monday look dry and rather warm and then possible 
impacts from Gustav would arrive on Tuesday and Wednesday. Will 
continue with 20 probability of precipitation for now Tuesday afternoon through Wednesday 
and slightly cooler temperatures...especially in the east. The 
models are showing a cold front moving through North Texas on 
Wednesday or Thursday and have started to trend the forecast in 
that direction with slight probability of precipitation and cooler temperatures. 
However...the front may have a hard time making it into Texas if 
the track of the associated upper level trough remains well to 
the north. 


Also of interest next week will be Tropical Storm Hanna. New 
models are converging on the storm slipping south of Florida and 
into the Gulf on Thursday.
