NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
527 am CST Thursday Nov 27 2014 


Aviation... 
concerns for this forecast period will be the winds shifting today 
and development of low clouds after 09z Friday. For today dry air 
and weak pressure gradient will provide VFR conditions. Will see 
light northerly flow this morning...becoming easterly this 
afternoon and southerly tonight. A few models...along with the 
simulated WRF are showing the development of low clouds across the 
Rio Grande plains after 06z and spreading north and east through 
12z. This fast return of low clouds can be overdone by the models 
at times. Will go ahead and include MVFR/IFR conditions after 09z 
west and 10-13z east. 


&& 


Previous discussion... /issued 358 am CST Thursday Nov 27 2014/ 


Short term (today through friday)... 
cold front has moved through south central Texas with surface high 
pressure settling in over our area. Temperatures will be up to 10 
degrees cooler than yesterday and fall back to below average today 
due cold advection in spite of sunny skies. Surface high moves off 
to the east by this evening allowing southerly lower level flow to 
return. Moisture increases leading to some low clouds Friday 
morning and then warming trend begins on Friday with temperatures 
back above average. 


Long term (friday night through wednesday)... 
southerly lower level flow strengthens this weekend with night 
and morning low clouds giving way to afternoon sunshine and well 
above average temperatures. On Sunday...a weak upper level trough 
moving across southern Texas and the low level jet may generate 
isolated showers across far eastern areas. An upper level trough 
moving east across the far northern United States and southern 
Canada this weekend forces a cold front south. European model (ecmwf)/GFS/Gem bring 
the front through south central Texas on Monday while navgem keeps 
the front north of our area. Will go with the GFS/ECMWF/Gem as the 
density of the cold airmass should allow the front to move through 
our area. Moisture convergence along the front is sufficient for 
isolated showers along and east of I-35 on Monday. Temperatures 
will fall back to below average by Tuesday. European model (ecmwf) and navgem show 
a stronger trough moving across the plains on Wednesday forcing 
another cold front south across south central Texas. The GFS shows 
a weak trough and no frontal passage. Will favor the GFS for now 
as it has been more consistent with a warming trend on Wednesday. 
The low level jet may generate some isolated showers on Wednesday.
