NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
1128 PM CDT Tuesday Aug 19 2014 


Aviation... 
the taf sites will remain VFR through this forecast with ceilings 
above 10000 feet tonight and scattered cumulus on Wednesday. Winds 
were southeast to south 12-16g26 knots earlier this evening after an 
outflow boundary moved through. However...expect speeds to come 
down after 06 or 07z and average around 12 knots the rest of the 
night. Pressure gradient to tighten on Wednesday and have speeds 
around 16 knots which should cover afternoon gusts of 20-24 knots.

&& 


Update... 
the isolated to scattered showers and thunderstorms that developed 
during the afternoon have nearly dissipated as of 9 PM. Isolated 
showers and maybe a thunderstorm or two may still occur east of 
the I-35 corridor through midnight. Have updated the grids to 
lower the probability of precipitation and adjust the hourly temperatures.

Previous discussion... /issued 325 PM CDT Tuesday Aug 19 2014/ 
regional satellite and radar data continue to play important roles 
in identifying mesoscale features that contribute to afternoon 
convection across North Texas. A couple of features continue to 
stand out across the region...most notably the presence of 
mesoscale vortices which can help focus convergence for new 
thunderstorms to develop. One of these is located across central 
Texas in The Hill Country...although they are just now beginning 
to destabilize sufficiently for thunderstorms across the southern 
counties. Another feature appears to be located across the far 
western counties this afternoon in close proximity to the weak 
upper low. Some forcing is evident in this area given the increase 
in the cumulus field and some isolated storms. Additional thunderstorm 
development is ongoing on what appears to be a remnant outflow 
boundary near the Red River. For the remainder of the 
afternoon...think the best chances for thunderstorms will remain 
across the western counties and north of Interstate 20 where 
moderate instability is in place. While large scale forcing is 
weak these subtle areas of enhanced low level convergence will be 
the favored areas for thunderstorms going into the evening. 
Farther southeast...widespread sea breeze convection is ongoing 
across southeast Texas and some of this could clip the far 
southeast counties. 


Most of the activity should wind down with the loss of daytime 
heating tonight as the upper ridge to the east continues to build 
into our area. The weak upper disturbance appears to get totally 
absorbed into strengthening southerly flow by late Wednesday. The 
remainder of the week into early next week looks like it will be 
dry with high temperatures near 100 degrees each afternoon. Some 
sea breeze thunderstorm activity could sneak into the southeast 
counties during the late afternoon through the end of the week but 
chances appear generally less than 20 percent. Dunn
