NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
854 am CDT Tuesday Sep 2 2014 


Update... 
light streamer showers have developed further west across the I-35 
corridor into the eastern Hill Country as moisture levels increase 
due to a stronger flow off the Gulf of Mexico. Have added probability of precipitation to 
include these areas for today and boosted slightly for areas near 
the coastal plains for this afternoon. Otherwise...no changes. 


&& 


Previous discussion... /issued 621 am CDT Tuesday Sep 2 2014/ 


Discussion...update for 12z aviation below. 


Aviation...broken stratus producing MVFR ceilings early this 
morning...with the greatest concentration along and north of a 
drt-hdo line. VFR ceilings developing around 16z at most 
locations. Increase in moisture today will lead to isolated to 
scattered rain showers/thunderstorms this afternoon. A few of these rain showers/thunderstorms 
could approach the I-35 corridor 20z-01z. At this time do not have 
mention in Sat/ssf/aus tafs due to coverage. Southeast winds 5-10 this 
morning increasing 10-15 kts in the afternoon with a few higher 
gusts near 20 kts. 


Previous discussion... /issued 351 am CDT Tuesday Sep 2 2014/ 


Short term (today through wednesday)... 
Tropical Storm Dolly is projected to move west from the western Gulf 
into Mexico late tonight. Satellite imagery shows a middle-level 
circulation to the north of the NHC defined surface position and 
track early this morning...and the new 06z NAM shows a good 
response to this feature by concentrating chances for moderate to 
heavy rains over deep south Texas today. Farther north high heat 
indices are expected across much of south central Texas for another 
day. A stubborn middle-level ridge axis over central Texas is still 
likely to hold of a deep intrusion of this unstable air into south 
central Texas today...but could set up more favorable conditions for 
good rain chances over the southern two- thirds of our south 
central Texas counties by late Wednesday. Deep surface to 500 hpa 
S/southeast winds are expected to push precipitable water values of around 2 inches up 
the Rio Grande Valley to near drt. Will favor the wetter European model (ecmwf) 
guidance over the drier GFS for Wednesday...but the Austin metropolitan 
area and points north are expected to be on the out fringe of 
these higher rain chances. Isolated 1-2 inch rainfall totals will 
be possible from a few training cells...but most of the activity 
should move fast enough to not present a concern for runoff. 


Long term (wednesday night through monday)... 
Wednesday night through Friday...the NAM and European model (ecmwf) continue to favor 
better rain chances associated with Dolly over mainly the Rio 
Grande plains into early Friday while the GFS remains drier. The 
mainly westward track of Dolly expected after landfall should 
leave only remnant moisture to spill into Texas...so there should be 
little in the way of vorticity to help concentrate rain chances. 
Thus after some low chance category pop days for the Rio Grande 
plains through Friday...model consensus shows the middle-level ridge 
becoming established back over the area by the weekend. Slightly 
higher moisture levels over the coastal prairies could keep a few 
daytime showers and thunderstorms over southern counties...but the 
resilient high pressure aloft will otherwise continue to extend 
the drought conditions for most areas. A tropical disturbance 
expected by model consensus to form over the eastern Pacific over 
the next couple days is not shown to produce a significant impact 
on the central Texas Ridge. The European model (ecmwf) and GFS do agree on the 
potential for an upper level trough to possibly modify the heat 
wave over the area by the middle of next week.
