NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
247 PM CDT sun Aug 30 2015 


Discussion... 
a broad longwave middle-level trough extended from the Southern 
Plains through the Mississippi...Tennessee and Ohio valleys today 
with a positive tilted ridge anchored west over The Rockies. A 
myriad of shortwave disturbances were embedded within the broad 
longwave trough...two of which over southwest Texas and eastern OK 
that may have an impact on North Texas sensible weather. A surface 
trough extended from Sherman...to d/fw...to near Comanche with 
higher surface dew points yielding SBCAPE values between 1000-2000 
j/kg to the east of this feature. Temperatures currently ranged 
from the middle- upper 80s in central Texas where a middle-high cloud 
canopy has lingered most of the day...to the Lower-Middle 90s north 
of I-20 where sunshine has been more abundant. 


Challenges abound once again today regarding convective initiation 
due to the mesoscale nature of lifting mechanisms noted above. 
North and central Texas remain sandwiched between the southwest Texas 
and eastern Oklahoma shortwave with both progressing slowly south. In 
addition...a deformation/frontogenetical region aloft was noted on 
water vapor imagery between these two shortwaves north of I-20. 
I am expecting isolated thunderstorms to develop by late afternoon 
between I-30 and the Red River to the east of the surface trough 
where heating has been strong and where a Theta-E axis has set up. 
Further south over central Texas...the majority of activity will 
remain in the form of light showers. Any pocket of insolation that 
does occur this afternoon across central Texas may allow for isolated 
thunderstorm development. 


Thunderstorms that do develop across the north and northeast 
counties could reach strong limits with gusty downburst winds... 
frequent lightning and possibly small hail. Rain chances should 
continue primarily south of I-20 for the evening as better forcing 
with the middle level frontogenesis shifting slowly south of I-20. 
After sunset...stronger isolated storms will likely weaken with 
loss of heating and diminishing instability. 


The area of middle-level deformation/frontogenesis shifts south into 
central Texas on Monday with much the County Warning Area under the influence of 
subsidence and drier air north of this feature. The shortwave 
further northeast will remain east of Paris and put that part of 
the County Warning Area within an area of subsidence as well. I have left the 
forecast dry Monday and Monday night with this in mind. The 
arklatex shortwave will retrograde westward to near the I-35 
corridor Tuesday-Thursday and will advertise diurnal convective 
chances east of I-35 and south of I-20 where daily seabreeze 
boundaries may aide in a focus for low convective chances. 


The middle-level trough will shift back to the east of the area 
Friday into next weekend...as middle level system deepens and 
organizes over the Pacific northwest. In addition...a potential 
Omega block pattern sets up over the upper Midwest and Great Lakes 
area which should keep North Texas dry and seasonable. 
Temperatures throughout the week are expected to remain near 
seasonal normals for early September.

Aviation... 
/issued 132 PM CDT sun Aug 30 2015/

Concerns...afternoon/evening thunderstorms. 


Metroplex... 
significantly veered winds will not diminish boundary layer 
moisture. And with sunshine this afternoon...MLCAPE values may 
exceed 1000j/kg. This instability will be essentially uncapped by 
late afternoon...when a few thunderstorms may develop. Although 
the old surface front is well to the northwest...winds this 
afternoon will not be strong enough to obliterate all the residual 
outflow boundaries...which may serve as a focus for initiation. 
With weak shear...the activity will be driven primarily by 
surface heating and should decay around sunset. 


Waco... 
showers have been slow to dissipate...and lingering cloud cover 
will limit surface heating this afternoon. However...temperatures 
are already in the 90s from Corsicana to Mexia...showing that 
increasing instability is not far away. With middle-level forcing 
remaining at the heat of the day...thunderstorms may develop 
within central Texas. The activity is not expected to be 
widespread...and weak steering flow will limit the amount of area 
individual storms will cover.
