NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
414 am CDT Tuesday Jun 28 2016 


Short term (today through wednesday)... 
the subtropical ridge is currently centered over The Four Corners 
region. A surface boundary is forecast to sag to the south into 
south central Texas later today. Upward forcing along the boundary 
will generate showers and thunderstorms later this morning over 
central Texas. These will spread to the south and west across 
south central Texas this afternoon due solar heating and outflow 
boundary interactions with the highest pops along and north of 
I-10. There is a potential for gusty winds due dcape near 1000 
j/kg and locally heavy downpours due precipitable waters  near 1.9 inches with the 
strongest storms. Showers and thunderstorms wane this evening with 
loss of heating. Showers and thunderstorms may develop early to 
mid Wednesday morning east of I-35 as the front slowly dissipates. 
Better upward forcing due to solar heating and outflow boundary 
interactions waits until Wednesday afternoon. Similar to today, 
gusty winds and locally heavy downpours are possible the strongest 
storms. Highest pops on Wednesday are from the southern Edwards 
Plateau to across the Rio Grande plains to near the coastal plains 
where the deeper moisture lingers. The subtropical ridge drifts to 
the southeast across New Mexico during the day bringing drier air 
into central Texas with no probability of precipitation there. Near normal temperatures 
are expected today and Wednesday. 


&& 


Long term (wednesday night through monday)... 
the subtropical ridge becomes centered over west central Texas on 
Thursday bringing drier air aloft and subsidence. However, the 
seabreeze may generate isolated showers and thunderstorms near the 
coastal plains Thursday afternoon. The ridge becomes centered over 
central Texas on Friday, lingers through the weekend, then splits 
by Independence day on Monday, however the axis lingers over south 
central Texas. No rain is expected due to warm mid level cap and 
subsidence. Above normal temperatures are expected through the 
Independence day weekend with heat indices possibly becoming 
elevated.
