NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
631 am CDT Friday Aug 28 2015 


Aviation... 
VFR conditions will continue at all North Texas taf sites through 
Saturday morning with only scattered to broken high clouds. A 
south to southeast wind will prevail at speeds generally less than 
12 knots. 


A cold front will approach the Red River tonight and bring a few 
showers and storms but all activity should stay north of the 
metroplex terminals.

&& 




Previous discussion... /issued 304 am CDT Friday Aug 28 2015/ 
not many sensible weather changes are expected for North Texas over 
the next week. The area currently remains on the eastern edge of 
a broad upper level ridge...which leads to warm temperatures and 
mostly clear skies. However...a weak cold front is still expected 
to traverse the plains and approach North Texas today but will 
likely stall across Oklahoma. Showers and storms associated with 
this feature will mostly remain north of our area as well...but 
some activity may slide into the North Texas counties that are 
near the Red River overnight tonight. 


Another feature that could possibly affect part of our area during the 
next week will be from an upper level low that is prognosticated to 
develop off of the la/MS coast today and slowly meander 
northward. Model guidance is still not consistent with the 
handling of this feature...but it is possible it could help 
provide some rain for our southeastern zones next week. 


For the most part...expect a relatively dry forecast for much of 
the area over the next week. Afternoon highs are expected to climb 
into the 90s with overnight lows dropping into the 70s...near 
normal temperatures for late August/early September.
