NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1155 PM CDT Wednesday Oct 1 2014 


Aviation... 
stratus with MVFR ceilings southeast of a kpez to khyi to kgyb line will 
spread northwest across remainder of south central Texas overnight. Ceilings 
may become IFR for a brief time. However...only mentioned at kdrt 
where lower level flow is weaker. Ceilings lift Thursday morning to 
VFR late morning with clouds becoming few-scattered cumulus. Isolated rain showers 
may develop on Thursday. However...chances are 20 percent or less 
and have left mention out of tafs. A cold front moves across south 
central Texas late afternoon into evening. Expect passage at kdrt 
around 02/22z and I-35 taf sites between 03/03z-05z. A line of 
rain showers/thunderstorms and rain will develop along the front over The Hill Country then 
move southeast across eastern and central parts of south central Texas 
during the evening into overnight. Have tempos of thunderstorms and rain and MVFR 
ceilings along with wind gusts up to 35 kts at I-35 taf sites from 
03/02z-07z. S to southeast winds 5 to 10 kts overnight increase to 10 to 
17 kts Thursday and then shift to north to northwest late Thursday afternoon 
out west and rest of the area in the evening into overnight.

Aviation...mostly clear skies and light winds will prevail 
across the region this evening. Ceilings will drop to MVFR 
overnight at all terminals with IFR ceilings at Sat...ssf...and 
drt around 09z. VFR conditions develop by late morning with south 
to southeast winds increasing to around 12 knots by the afternoon. 
A cold front will approach the area Thursday afternoon. Will 
mention thunderstorms in the vicinity at all terminals after 22z with prevailing thunderstorms and rain/MVFR 
conditions at aus and Sat by 02z Friday. 


Previous discussion... /issued 311 PM CDT Wednesday Oct 1 2014/ 


Short term (tonight through Thursday night)... 
Summer-like temperatures are back this afternoon with heat indices 
in the middle to upper 90s. Clouds continue to dissipate out west 
with partly cloudy skies prevailing along and east of Interstate 35. 
Area radars show isolated showers and storms across the coastal 
waters and out west a few storms over the serranias del burro 
mountains. None of this activity is anticipated to affect our area 
the rest of this afternoon and evening. An increase of low level 
moisture in combination with a low level jet with 30 to 40 knots 
will bring rain chances late tonight into Thursday morning. After 
a cloudy morning with some light rain-showers mainly east of 
Highway 281...clouds will scatter/dissipate mainly across the Rio 
Grande and Edwards Plateau. Another warm day is in store on 
Thursday before big changes come around during the evening and 
overnight hours. 


An upper level trough will dig southeastward tonight and over the 
Southern Plains on Thursday. A surface cold front will push ahead 
of the upper level shear axis. The timing of the frontal passage 
across south central Texas is estimated to be Thursday evening from 
about 7 PM to midnight Friday (hill country and locations along 
Interstate 35). After midnight Friday...the cold front should be 
moving south over areas along Highway 90 and southern counties. 


As the cold front pushes across The Hill Country during the early 
evening hours...there is a slight chance for strong to severe 
thunderstorms mainly north of a Harper to Austin to Lexington line. 
The main hazard treat will be thunderstorm damaging winds. Can't 
rule out small hail and localized heavy downpours. As the front 
advances to the south the potential for heavy rain increases due 
to deeper moisture available and better instability. Storm 
rainfall totals for the duration of the event should range from one 
to three quarters of an inch with up to two inches over some spots. 


Long term (friday through wednesday)... 
by Friday morning (7am)...the cold front should be exiting our 
southern counties with some lingering showers across those areas. 
In the wake of the front...expect breezy northerly winds and 
clearing skies as a moderate surface high pressure system settles 
over North Texas. Northwest winds aloft and northerly winds at the 
surface with a cooler airmass spreading across the area will 
promote pleasant and slightly below temperatures Friday into the 
upcoming weekend. Surface southerly flow returns on Sunday as high 
pressure pushes to the east...resulting in morning clouds/partly 
cloudy skies in the afternoons and a slightly warming trend for 
the beginning of next week.
