NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
612 PM CDT Friday Jul 25 2014 


Aviation... 
VFR through Saturday evening with only few to scattered daytime 
cumulus. A south wind will prevail generally under 12 knots. These 
typical July conditions should continue until a cold front arrives 
on Monday.

Previous discussion... /issued 351 PM CDT Friday Jul 25 2014/ 
an upper level ridge will continue to dominate the weather across 
north and central Texas through the weekend. The East Part of the 
upper level ridge will start to weaken as an upper low currently 
over western Saskatchewan...west of saskatoon...moves southeast 
across the Great Lakes states. This will allow a cold front to 
move down the plains to near or just south of the Red River by 
Monday morning. Thus have added some 20 to 30 percent probability of precipitation along 
and north of the I-20 corridor for the 06-12z Monday period. The 
12z run of the GFS brings the cold front down through central 
Texas Monday night. The 12z European model (ecmwf) brings the front south of the 
Red River by 12z Monday to south of the I-20 corridor by 
18z...but then stalls it. The European model (ecmwf) then indicates that the front 
will sink south into central Texas Tuesday. We should see 20 
percent probability of precipitation across all but the extreme south Monday...and a 20 
percent chance across most of the region Monday night through 
Wednesday. 


As a series of short waves rotate around a strong upper level low 
over northern Quebec...the trough in the east will deepen. This 
will result in increasing northerly flow aloft across the plains. 
A series of short waves will bring chances of showers and 
thunderstorms for later half of the week. For now will keep the 
highs probability of precipitation across the northeast half Wednesday night...and the 
eastern 2/3s for Thursday. Another round of storms is possible 
Thursday night and Friday. 


Temperature wise...it will be a hot weekend with highs in the middle 
90s to 102 degrees. We will see temperatures cool slightly early 
next week...followed by additional cooler later in the week. 
Exactly how much cooler on any particular day will be dependent 
on cloud cover and precipitation. Right now it looks like Thursday 
and Friday may be around 10 degrees below seasonal normal highs.
