NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
627 am CDT Monday Sep 22 2014 


Aviation... 
only concern this forecast period will be the front. This weak 
cold front will move south across the region today into this 
evening. Isolated showers or thunderstorms are possible this 
afternoon into the evening. Due to the uncertainties with timing 
and location...plus low probabilities have not included in any 
rain showers/thunderstorms and rain in the terminal forecast at this time. Will monitor the 
trends throughout the morning and make updates as necessary. After 
some MVFR ceilings at kdrt this morning...VFR conditions are 
expected for the remainder of the forecast. Winds will be east/NE at 
5-10 knots. Krdt will have east-southeast winds 5-10 knots.

Previous discussion... /issued 317 am CDT Monday Sep 22 2014/ 


Short term (today through tuesday)... 
light showers have developed over the Rio Grande plains early this 
morning...but these are now mostly across the border in Mexico. 
Meanwhile...the weak cold front has made it as far south as 
Hillsboro...with convection popping up about 100 miles behind 
frontal passage. The primary forecast issue today is the Prospect for 
convection behind the front. Blended tpw imagery shows pooling of 
precipitable water immediately behind the surface frontal passage...but only to 1.5 inches. 
Otherwise...it/S dry ahead of the front with precipitable water in the 1-1.25 inch 
range across our area. The convection-allowing mesoscale models 
are in good agreement and depict deep moist convection firing 
behind the front around 21-22z in our area. The best chances for 
rain will be in a band 50 miles either side of I-10...but we 
decided to include a generic 20 percent pop for the entire area to 
allow for timing uncertainty. Low probability of precipitation will be kept through 06z 
for the coastal and Rio Grande plains...but otherwise dry air will 
push into the area. 


Long term (tuesday night through sunday)... 
high pressure will maintain low humidity with cool nights and mild 
afternoons Tuesday through Thursday. We shaved a degree or two off 
model consensus lows and added a degree or two to highs to account 
for the dry atmosphere...which should promote a large diurnal 
temperature range. 


The global models are in fair to poor agreement in the medium 
range...with the GFS and Canadian similar...and the GFS most 
consistent run-to-run...while the European model (ecmwf) is unsettled. The model/S 
depiction of a cut-off low range from centered over Texas to centered 
over the northwest Gulf. Despite the differences...there is good 
agreement Gulf return flow only gets weakly re-established. The 
best combination of moist air and lift will be late Thursday night 
into Friday...so low probability of precipitation were included for those periods. Otherwise... 
expect a slow return to near normal temperatures and humidity.
