NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
1248 PM CDT Tuesday Sep 16 2014 


Update... 
as noted in the aviation discussion...isolated thunderstorms will 
be possible across the forecast area this afternoon. Thus have 
updated the forecast to include this. Have also increased this 
afternoon/S highs by a few degrees as thinning middle-high clouds are 
allowing for a little more heating.

Aviation... 
/issued 1245 PM CDT Tuesday Sep 16 2014/ 
VFR conditions should prevail throughout the entire taf cycle. 
Satellite observations and hi-res model guidance suggests that 
isolated showers may be possible this afternoon in response to the 
slight thinning of middle and upper level cirrus deck and subsequent 
daytime heating. As a result...have included a mention of vcsh at 
all taf sites. Confidence is too low at this time to include 
thunder in any tafs for this afternoon...but may become warranted 
should middle and upper level cirrus continue to thin more than 
currently expected. Otherwise...scattered cumulus and towering cumulus should 
continue with afternoon heating. Towering cumulus...cu...and any showers that 
develop should wane with the loss of daytime heating with light 
northeasterly and easterly winds veering more to the south and 
southwest in response to the deepening Lee trough across Colorado.

Previous update... 
update... 
the weather across the region today will remain relatively quiet. 
The 12z forward radiosonde observation still shows a pretty moist sounding which is the 
same as the soundings that we have seen for the last few days. 
With no major sources of lift /only a weak short wave embedded in 
the upper flow/ and no significant surface boundaries...we are 
counting on diurnal heating for isolated to scattered showers to 
develop today. Have lowered the rain chances to isolated across 
the north and slight chance across the south for the rest of 
today. Rainfall amounts will be light...with most sites that 
receive rain picking up less than 1/10th of inch. Temperatures 
will be dependent on how many breaks we see in the middle and high 
level clouds. Most areas should reach the middle 80s to around 90 
degrees.

Previous discussion... /issued 347 am CDT Tuesday Sep 16 2014/ 
the combination of elevated moisture associated with Tropical 
Storm Odile and weak short wave energy embedded in northwest flow 
aloft will bring a chance of showers to North Texas today. The 
best chances for measurable rainfall will be across the southern 
zones where moisture and lift will be the most favorable. Lapse 
rates will remain nearly moist adiabatic through the day and 
thunder appears unlikely for the most part. However...a brief 
storm or two is not completely out of the question across the 
southern zones. Earlier thinking was that a weak cold front would 
move into North Texas today and provide an additional source of 
lift for precipitation but current surface analysis shows only very 
weak pressure rises behind the approaching front. Therefore...it 
is likely that the front will remain north of the Red River today 
so we will reduce the chances of measurable precipitation across 
the northern half of the region to 20 percent. 


The upper pattern will not change much tonight through Thursday with 
high pressure across the west and a long wave trough in the east. All 
models continue to indicate that a series of shortwaves will move 
across The Hill Country and the southern portions of North Texas 
Wednesday through Thursday and bring scattered rain and 
thunderstorms. It appears that the best chances for appreciable 
rainfall will remain across The Hill Country but we will carry 
chance probability of precipitation across about the southern half of the forecast area 
Wednesday through Thursday. 


Rain chances will decrease Thursday night as the short wave energy 
moves southeast and upper level high pressure builds across the 
state. Large scale subsidence underneath the area of high pressure 
should dominate the region Friday through Saturday and keep rain 
chances low. 


Some changes are on the way late in the weekend through early next 
week as an upper level trough moves east across the middle of the 
nation. While most of the energy associated with this system will 
remain north of the region....the passage of the trough axis will 
allow a cold front to move south across the plains and reach North 
Texas Saturday night. The GFS...Canadian and European model (ecmwf) solutions are 
in decent agreement on the timing of the cold front and the 
associated precipitation...although the European model (ecmwf) is a bit faster 
with the front. We have decided to raise probability of precipitation slightly for Sunday 
due to the overall model agreement. Much drier air will filter in 
behind the front Sunday night and this air will remain in place 
through at least the middle of next week. 


Temperatures through the weekend will be near normal for this time 
of year with highs in the 80s to lower 90s and lows in the upper 
60s and 70s. Temperatures on Sunday and Monday should be a bit 
cooler with lows from the upper 50s to the upper 60s and highs 
generally in the 80s.
