NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
1246 PM CDT sun Apr 20 2014 


Aviation... 
after a morning of widespread IFR...ceilings are slowing rising 
into MVFR categories. Satellite shows some thinning taking place 
in some locations so went with some VFR conditions by the 21-22z 
time frame later this afternoon. Higher confidence out in drt of 
some partial clearing as satellite loop shows clearer skies 
advancing eastward. Time tool puts the clearing line into drt 
around the 21z mark. Chances of rain remain too small to mention 
for the rest of today or tomorrow. Deep moisture remains in place 
for tonight and early Monday so looking for a repeat of IFR ceilings 
and some lower visibilities as well. Some patchy drizzle and -ra may also 
be around. Trough axis is pushing east overnight so westerly middle 
level winds should allow for quicker VFR by around 18z Monday. But 
the morning hours will be socked in once again all taf sites. Scattered 
convection may affect aus late in the day on Monday but timing and 
low pop keeps the confidence low enough to leave out of the tafs 
at this point.

Previous discussion... /issued 1225 PM CDT sun Apr 20 2014/ 


Update... 
the large cloud coverage and light rains over the area will 
keep high temperatures several degrees lower than previously 
forecasted. Therefore...adjusted maximum temperatures for this 
afternoon based on latest GFS/lamp guidance.
