Area forecast discussion 
National Weather Service Fort Worth Texas 
1222 PM CDT Sat Aug 30 2014 


Aviation... 
a positive tilt upper trough continues to dampen while moving 
east across the Southern Plains. Most of the energy associated 
with this system has shifted east of North Texas...and likewise 
the brunt of today/S convective weather should remain east of the 
region. However...the southwest edge of the trough still lingers 
overhead and isolated convection can be expected this afternoon. 
The morning sounding indicates plenty of instability along with 
1.5 inch precipitable waters ...and a convective temperature in the lower 90s. 
There is temptation to include a thunderstorms in the vicinity at area airports...but due to 
the isolated nature of the convection...probabilities appear too 
low to mention. But as always we will keep an eye on trends this 
afternoon...and if higher coverage develops farther west we would 
amend to include a thunderstorms in the vicinity for a few hours. 


Otherwise...MVFR conditions have lingered through middle day at kdal 
but should be improving shortly. VFR can be expected 
this afternoon through the overnight hours...with a brief period of 
MVFR stratus possible again Sunday morning.

Update... 
the isolated showers in the southwestern zones have nearly 
dissipated. We did an update earlier to remove the mention of 
isolated morning showers/thunderstorms from all but the extreme 
southwestern and extreme northeastern zones. Additional 
shower/thunderstorm development is expected after 2 PM so we left 
the 20 percent probability of precipitation area wide for this afternoon.

Previous discussion... /issued 408 am CDT Sat Aug 30 2014/ 


Early morning water vapor satellite imagery showed a shortwave 
trough over northern Missouri moving off to the northeast with a 
cyclonic shear axis extending south across Oklahoma and over 
northwest Texas. A second...but weaker...shortwave trough was 
observed over southeast Colorado...moving southeast towards the Texas 
Panhandle as of 08z/3am. It was difficult to pick out this second 
trough on 00z upper air analysis as this feature was masked by 
height rises following the stronger trough exiting the region to 
the northeast. However...there were some subtle height falls and a 
cyclonic wind shift observed over eastern Colorado and northern 
New Mexico at the 250 mb level which are likely associated with 
this secondary trough. Otherwise...upper air analysis indicated 
upper level ridging over the southwest and southeast Continental U.S....which 
are expected to bridge over the Southern Plains by early next week 
becoming the dominant weather feature over the region for much of 
the week ahead. 


Early morning infrared satellite imagery showed a band of middle- 
level clouds developing along a line from Gainesville to Mineral 
Wells to Brownwood. This is likely associated with some weak 
forcing for ascent associated with the trailing cyclonic shear 
axis aloft that is moving east over the area right now. The forward 
00z radiosonde observation indicated a fairly significant subsidence inversion at 
the 525 mb level yesterday evening...so chances are that this 
developing middle-level accus will not result in thunderstorms this 
morning. However...with no commercial airline activity to grab 
radiosonde observation data from recently...it is difficult to know the strength of 
this elevated cap early this morning over the region. Went ahead 
and mentioned isolated thunderstorms along and southeast of this 
line this morning with a 10 pop to account for the possibility 
that lift has cooled/removed this elevated cap this morning. Once 
the 12z radiosonde observation is in...or after we get some morning air traffic 
processed through dfw and Dal...we will have a better idea of 
morning elevated thunderstorm chances. 


Otherwise...the primary feature we will be watching for today is 
the secondary shortwave trough moving southeast towards North 
Texas this afternoon. The large scale forcing for ascent 
associated with this trough is expected to be weak...and mainly 
focused over the northwestern County Warning Area this afternoon. The best way to 
track the lift associated with this trough might be to look for 
500 mb cold air advection. Outside of looking at a dynamic 
tropopause map...it's just not that easy to find the lift 
associated with this trough. 500 mb cold air advection seems to 
line up well with the primary area of lift associated with the 
trough this afternoon. 


00z radiosonde observations and early morning GOES sounder imagery show the deepest 
moisture in place over East Texas and the Texas Gulf Coast...with the 
driest air observed over the Texas Panhandle. As a result...we 
will be getting the best lift this afternoon where the moisture is 
most lacking...and we will have more or less neutral forcing where 
moisture is deepest. As a result...went ahead and just expanded 
the 20 probability of precipitation we had over the eastern County Warning Area to cover the entire area 
for this afternoon into the early evening hours of the day. 


Because lift and moisture do not line up well...think that 
wherever storms develop...they will be limited in coverage to 10 
to 20 percent across the region. High resolution models are 
favoring thunderstorm development along and west of the Interstate 
35 corridor...closer to the lift associated with the shortwave 
trough. Thunderstorms to the east will most likely be dependent 
upon peak heating/buoyancy as the primary lifting mechanism... 
leading to a more chaotic development of storms this afternoon. 
Forecast soundings indicate little cap for surface based free 
convection this afternoon across the region...so confidence in 
storms developing is high...despite the expectations that coverage 
will remain isolated in nature. Deep layer shear is expected to 
hold in the 15 to 20 knots range...so no organized severe weather is 
expected at this time. Localized strong wind gusts associated with 
downbursts...and heavy rainfall are the expected thunderstorm 
hazards...aside from cloud to ground lightning. 


Expect thunderstorm activity to dissipate quickly after sunset as 
the forcing for ascent associated with the secondary shortwave 
trough is not expected to be strong enough to keep storms going 
with the loss of daytime heating. 


Sunday...the shortwave trough is expected to continue off to the 
east overnight...and is expected to be east of the County Warning Area by Sunday 
morning. This will leave the County Warning Area under weak subsidence aloft with 
no obvious upstream shortwave troughs. The consensus of guidance 
is for zonal flow to build over the northern and central Continental U.S. 
While upper level ridging builds over the southern third of the 
Continental U.S.. the only exception to this is along the Texas Gulf Coast where 
models hold on to a weak upper level disturbance at least through 
Sunday afternoon. With this feature holding in place...but the 
rest of the County Warning Area seemingly dominated by weak subsidence 
aloft...went ahead and maintained 20/30 probability of precipitation for locations along 
and southeast of a line from Athens to Killeen Sunday afternoon. 
These locations are closest to the weak upper level disturbance 
and hold on to the deepest moisture...so some unorganized 
afternoon convection cannot be ruled out. For the remainder of the 
County Warning Area however...dry conditions should prevail as subsidence builds 
weak capping over the region. 


Monday through Friday...the consensus of guidance is to build 
upper level ridging over the County Warning Area for the week ahead. The GFS 
continues to hold on to the weakness aloft over the Texas/la Gulf 
Coast...but the Canadian and European model (ecmwf) favor ridging dominating the 
region...so went ahead and removed the probability of precipitation the previous forecast 
had over the southeastern County Warning Area each afternoon from Tuesday through 
Thursday. The only way the upper level weakness along the Texas/la 
Gulf Coast is going to be maintained is through daily persistent 
and somewhat vigorous thunderstorm activity. If that activity is 
observed Sunday through Tuesday...we may have to adjust the 
forecast to place these probability of precipitation back in. Because the GFS maintains 
this feature in the absence of focused thunderstorm 
activity...sided with the European model (ecmwf) and Canadian which made more 
conceptual sense at this point. 


Ridging aloft should keep US dry and seasonably hot for the week 
ahead. Kept temperatures below 100 degrees as the ridge aloft is 
not super strong...and we maintain southerly winds through the 
entire week due to Lee side troughing associated with zonal flow 
over the northern and central Continental U.S.. persistent southerly winds 
will keep some shallow moisture in place resulting in some morning 
stratus intrusions...and an afternoon fair weather cumulus field 
each day...both of which should prevent a big heat wave from 
setting up over the region.
