NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
647 PM CDT Friday Mar 27 2015 


Update... 
made minor adjustments to the hourly dewpoint grids. Dewpoints in 
the 30s remain across much of the region...but these values 
should slowly rise this evening and overnight. No other 
significant adjustments were needed to the forecast.

Previous discussion... /issued 619 PM CDT Friday Mar 27 2015/ 


Discussion...update for 00z aviation below. 


Aviation...VFR conditions under clear skies through the taf 
period. Winds diminishing to around 5 kts or less this evening and 
overnight. SW to southeast wind developing and increasing to 12-15 kts 
15z-18z...a few gusts around 25 kts possible Sat afternoon at 
aus. 


Previous discussion... /issued 304 PM CDT Friday Mar 27 2015/ 


Short term (tonight through Saturday night)... 
pleasant weekend weather is in store with light winds tonight 
leaving brisk morning lows in the middle 40s to middle 50s. An amplified 
ridging pattern aloft over The Rockies will produce more warm 
afternoons Saturday into Sunday with the warming trends being 
helped by southwesterly low level winds. Winds should again be mostly 
decoupled Saturday night...but the gradually increasing southerly 
flow should lead to warmer dewpoints and less cooling in the 
valleys of The Hill Country for Sunday morning. 


Long term (sunday through friday)... 
skies should again be mostly sunny for the most part Sunday...with 
some increasing middle and high clouds possible. Sunday night...the 
low level moisture catches up...and some morning low clouds and 
patchy sprinkles are forecast for Monday morning. Models continue 
to show good consistency and grouping for a low amplitude upper 
trough to pass directly over the south central Texas to enhance rain 
chances for Tuesday into Tuesday night. Given the track...there 
could be a potential for some Spring hail...but the weakness of 
the upper pattern does not lend to US being worried about strong 
storm hazards at this time. Another warm afternoon should follow 
in the wake of the disturbance Wednesday...with Thursday also 
likely to see temperatures near or above early Spring normals. Another 
weak to moderate cold front is depicted for next Friday 
morning...with the European model (ecmwf) looking slightly stronger with the 
surface ridge than the GFS.
