NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
322 PM CST Tuesday Mar 3 2015 


Short term (tonight through Thursday morning)...fog will be the 
issue again tonight. Areas along the I-35 corridor are still 
seeing some visibilities below a mile. Fog will expand in coverage 
across the area this evening and overnight...becoming dense where 
it already is not. A dense fog advisory will likely be needed for 
a portion of the area. Patchy drizzle and isolated showers 
possible along and east of I-35 overnight and through midday 
Wednesday. Elevated showers may clip far northwest areas of the 
County Warning Area during this time with approach of middle level shortwave and 
moist axis. 


Much advertised cold front still on track to enter northern areas 
of The Hill Country and central Texas Wednesday afternoon. Cold 
dense airmass behind this front...with front accelerating quickly 
through the remainder of the County Warning Area early Wednesday evening. Very 
sharp temperature drop behind the front...and strong pressure 
rises will result in windy conditions areawide. Winds potentially 
approach Wind Advisory criteria along the edge of the Escarpment 
and eastward through the coastal plains. 


The forecast philosophy has not changed much with respect to precipitation 
chances behind the front and potential for winter precipitation across 
the northern half of the County Warning Area. Deep forcing continues behind the 
front peaking west to east between 06z-12z as middle level shortwave 
passes by. Favorable upper level jet positioning will assist in 
ascent across the northeast half of the County Warning Area. Top down look at 
forecast sounding as well as sref plume from NCEP indicate 
predominate precipitation type will be freezing rain mixing to sleet. 
There will be a very slight chance and small window for light 
snow to mix in across the far northern Hill Country Thursday 
morning. 


Areas along and north of a Comstock to Concan to Helotes to San 
Marcos to Lexington line are currently where we are expected the 
potetnital for ice accumulations...ranging from a trace to 1/10 
of an inch. This includes the Austin metropolitan area. Can not rule out 
some sleet south of this line...but ground temperatures should be 
above freezing. Can not rule out a few spots along a kerrvile to 
Johnson City to Georgetown line seeing accumulations just over 
1/10 of an inch. 


A Winter Weather Advisory will likely be issued in the next 
forecast package...and depending on quantitative precipitation forecast trends a Winter Storm 
Watch/warning may be required for The Hill Country and portions of 
central Texas. 


Jr 


&& 


Long term (thursday afternoon through tuesday)...models have 
trended faster with precipitation exiting the area Thursday morning...and 
we no longer carry mention of weather Thursday afternoon. A more 
widespread freeze is likely Friday morning as clouds decrease due 
to continued drying and a cold surface ridge over our area. The 
middle level shortwave reforms into a low across northern Baja California then 
opens and moves across southern Texas this weekend. There are 
differences between GFS and European model (ecmwf) with amplitude and speed of this 
system. Have low chances for rain in the forecast Saturday night 
through Sunday night. More seasonable temperatures finally return 
to the forecast early next week...depending on speed of 
aforementioned system
