NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
645 PM CDT Tuesday Aug 4 2015 


Aviation... 
no aviation concerns expected for the 00 UTC taf cycle and VFR 
conditions should prevail. 


For the metroplex taf sites...late afternoon cumulus is expected to 
dissipate with the loss of daytime heating and only a few high 
clouds are expected during the overnight hours. On 
Wednesday...VFR cumulus should develop middle morning and will persist 
through the early evening hours. Southerly winds of 10-12 knots are 
expected through the entire taf cycle. 


For the Waco taf site...expect VFR cumulus to decrease in coverage 
through the evening hours. Low level moisture is expected to stream 
northward overnight which may result in the development of brief 
MVFR ceilings. For now...have opted to leave mention of MVFR stratus out 
of Waco taf site...but will monitor observational trends and re- 
examine the potential with the 00 UTC guidance for the 06 UTC 
tafs. 


Note...hot conditions are expected to occur at all taf sites on 
Wednesday and heat index values of 104 to 107 degrees will be 
possible. Individuals that work outside are urged to stay 
hydrated and take frequent breaks when possible.

Previous discussion... /issued 312 PM CDT Tuesday Aug 4 2015/ 
showers and isolated thunderstorms associated with a weak 
shortwave have remained mainly north of the Red River this 
afternoon. An isolated shower or two cannot be ruled out over the 
northern most counties later this afternoon and this evening as 
the upper level feature continues to drop southeast through the 
Southern Plains...but activity will remain isolated if at all. 


The more pressing part of the forecast will be development of a 
middle and upper ridge currently centered over the Desert Southwest. 
The ridge is prognosticated to shift east with time as the weak shortwave 
trough moves east of the region. The ridge axis Will Park itself 
overhead tomorrow and remain in place through at least the early 
part of next week. 


Triple digit high temperatures will begin as early as tomorrow 
across much of the area...with high temperatures creeping a degree or so 
higher each afternoon through the weekend. Maximum heat index 
values should exceed 105 by Wednesday afternoon across roughly the 
northern half of the region...and a heat advisory will go into 
effect for areas generally along and north of a line from Cisco to 
Waxahachie to Emory beginning 18z Wednesday. This area will likely 
be expanded south to include most of North Texas for Thursday 
through the weekend...with the specifics being better known by the 
issuance of tomorrow/S afternoon package. At this time...it 
appears that the warmest days will be Friday through Monday...with 
high temperatures of 102 to 105 becoming common along with maximum 
heat indices 105-109. 


Either way...it looks like the ridge is here to stay for a while 
with the triple digit heat residing along with it. Some relief 
will be possible as we approach the middle part of next week...and 
another weak front eases south into the area. At this time we will 
include some 20 probability of precipitation in the extended portion of the forecast with 
not much else showing up in the foreseeable future.
