NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
255 PM CST Monday Dec 22 2014 


Short term (tonight through Tuesday night)... 
low clouds have dissipated from nearly all of the forecast area 
this afternoon...except for a small patch near del Rio. Middle/high 
clouds will continue to stream from west to east over the region. 
There is a wind shift that is beginning to enter the northwestern 
County Warning Area. This wind shift is most likely not the true cold front as the 
cooler air and pressure rises remain well to the north. Hi-res 
models are showing the winds across most of the County Warning Area returning to 
light from the east/southeast overnight. This could lead to fog 
potential across the southeastern counties where surface moisture 
may pool ahead of the boundary. The north winds and cold air will 
reach the the County Warning Area tomorrow morning. Day time highs will likely be 
just before the front moves through with slowly falling or nearly 
steady temperatures expected for the remainder of the day. Hi-res 
model guidance as well as the global models continue to suggest the 
northern and eastern zones will have enough moisture in a layer 
extending from near the surface to about 700 mb for some shower 
activity ahead and behind the boundary. There will be a dry slot to 
the southeast of the upper low that moves over the area that will 
limit moisture in the middle-levels available for deep convection. 
Any rain totals will remain light...generally less than 0.15 
inches. Rain is expected to end by tomorrow night with cloudy 
skies slowly clearing. Lows will reach near freezing in The Hill 
Country to upper 30s elsewhere. 


&& 


Long term (wednesday through monday)... 
Christmas evening...clear skies and breezy northwest winds will be 
prevailing for most of the day. Highs will be on the cool 
side...in the lower 50s to near 60 degrees. Clear skies and light 
winds will lead to decent radiational cooling conditions across 
the area. Lows Christmas morning will range from the upper 20s to 
middle 30s with much of the area at or below the freezing mark. 
South winds will return as well Christmas morning and highs will 
rebound into the 60s. The next upper trough will pass through the 
plains on Friday and this will send another strong cold front into 
the area Friday evening. Little to no precipitation is expected with this 
front but The Hill Country could see freezing temperatures once 
again Sunday morning. South winds return Monday and a slow warming 
trend will begin. The GFS is hinting at weak showers associated 
with the warm air advection and will forecast 20 probability of precipitation across the 
eastern zones Monday.
