NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
352 am CDT sun Apr 19 2015 


Short term (today through monday)... 
the 00z upper air analysis showed the persistent upper low which 
has been nearly stationary to our west over the past several days 
beginning to move northeast. The center of the low at 500 mb was 
located near eastern Colorado. Models are consistently 
weakening/moving the low center east this afternoon with an open 
wave expected to be near northeast Oklahoma by this evening. The 
low is being forced eastward by a another strong low dropping from 
Canada into the northern Continental U.S.. as the upper low moves east...it 
will allow a cold front to move through the region late this 
afternoon and evening. The 06z surface analysis showed a surface 
low near Childress with a weak high near Houston. Before the 
frontal passage...breezy southwesterly flow at the surface will setup ahead 
of the approaching cold front. This setup should equate to warm 
afternoon temperatures. Ground moisture should keep temperatures a couple 
of degrees cooler and will undercut mavmos slightly for afternoon 
highs. The focus of todays forecast then shifts to the threat of 
convection along the frontal boundary as it moves through the area. 
The 850 mb analysis shows a sharp cutoff in moisture from our 
western County Warning Area to the eastern counties. If any storms do develop it 
will be across the eastern counties where the best moisture 
coincides with the frontal boundary. Most activity will be well 
east and northeast of our County Warning Area where the best dynamical forcing 
will be today with the exiting low-pressure system. Storm 
processes in our County Warning Area will be primarily driven be mesoscale forces 
such as frontogenetical forcing along the advancing cold front. 
If any storms do develop they will have a very unstable airmass to 
tap into to quickly become strong/severe. Shear values near 40 
knots will also support the threat for severe weather. The Storm 
Prediction Center has placed areas east of an Austin to Seguin to 
Pleasanton line in a slight risk for severe weather this 
afternoon. Agree with this forecast as the threat today should be 
highly conditional. Overall coverage of storms should be low...but 
any storms that do develop could quickly become severe with large 
hail and damaging winds being the main threat. 


The threat of storms will slowly shift south after 00z with all 
storms exiting the County Warning Area by 06z. The front will bring in cooler 
temperatures which leaves todays as the warmest day of the 
forecast period. Continued weak northerly flow at the surface and 
some cloud cover should keep high temperatures Monday in the lower 
to middle 70s. 


&& 


Long term (monday night through saturday)... 
the extended forecast is a tough one as nearly zonal flow aloft sets 
up across the region. This will enable surface cyclogenesis to 
develop on the Lee side of The Rockies on Tuesday. 850 flow will 
also increase from the south Tuesday with 30-35 knots prognosticated by 
medium range guidance. This will allow for a low chance of rain 
associated with warm air advection tues-Thursday. It is tough to 
pin down specific rain chances and locations each day during this 
period at the present time. By Friday...stronger upper lift 
associated with an upper low will possibly combine with a cold 
front to give most of the area another decent chance of rain. It 
is much too early to get into specifics regarding precipitation amounts 
or severe chances. Temperatures for the work week will remain near 
seasonal normals with highs in the 70s and lows in the 50s/60s for 
much of the region.
