NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
917 am CST Wednesday Jan 28 2015 


Update... 
main forecast from the morning package is on track. Have decreased 
dew points slightly for the morning period based on current 
observations. Also upped the wind speeds slightly for this 
afternoon based on the morning models and soundings. Looks like 
sustained south winds around 10-12 knots with some gusts to 20 
knots are possible between noon and 6 PM across much of south 
central Texas. Trended the rest of the hourly weather grids to 
continue morning observational trends.

Aviation... 
VFR skies with few-scattered clouds above 10k feet will prevail today 
through the overnight. Lower level moisture returns by early 
Thursday morning along and southeast of the I-35 corridor with 
IFR/MVFR visibilities in br and few-sct003 developing after 09z and 
persisting until 16z. There may be some LIFR/vlifr vsbys/cigs. 
However...due to uncertainty will leave mention out of tafs. Variable 
winds less than 5 kts early becomes S to southeast at 5 to 12 kts with 
some gusts to 20 kts by midday. Just beyond this forecast...a cold 
front moves across the area Thursday afternoon switching winds to 
north to NE. 


Previous discussion... /issued 336 am CST Wednesday Jan 28 2015/ 


Short term (today through thursday)... 
another well above average day is in store today...in fact...if 
forecast highs are realized today...records will be set at 
multiple locations across south central Texas...namely Camp 
Mabry and San Antonio. 


Spent a good deal of time considering what...if any variable would 
prevent these highs from being realized and that would likely be 
the 10-15 miles per hour wind field prognosticated to develop this afternoon. The 
southerly fetch could work to add some surface moisture into the area 
and prevent highs from getting into the 80s today. However...clear 
skies...and a 4-5 degree cool MOS bias yesterday would suggest 
that continuing to go above guidance is a good bet. 
Therefore...forecast highs in the lower 80s was decided on. 


A weak cold front passage Thursday will begin a more active period 
over the weekend. Only short term concern will be fog development 
Thursday morning ahead of the front where return flow and 
isentropic lift will be strongest. For now...this looks to be 
generally an area south and east of the i35 corridor...closer to 
the Gulf Coast. 


Long term (thursday night through tuesday)... 
by Friday...a deepening 500 mb low over the SW Continental U.S. And Baja California 
California will send embedded shortwaves downstream into West 
Texas along with some Pacific moisture. The upper level energy 
will bring pop chances into the forecast by Friday...but believe 
this is a pretty small chance as it will take time for the top 
down moistening process to take place. However overnight Friday 
and Saturday morning...deep lift and precipitable water values in the 1.2-1.3 
inch range should set up the whole County Warning Area for a healthy 48 hour 
period of rainfall with the bulk of the quantitative precipitation forecast taking place Saturday 
and Saturday night. 


As it stands now...lift is decent but not eye popping but a strong 
850 mb low level jet should keep rain rates respectable. Its still too far 
out to pinpoint where heavier rain rates would develop with this 
broad upper level support...so went with the more general 48 hour 
total that wpc suggested (up to 1 inch) for the weekend. Think its 
a good chance localized areas will see higher than that but kept 
things general for the time being. Middle level lapse rates are 
somewhat steep Saturday afternoon as well so kept the slight 
chance thunder mention as well. 


Through Sunday and into Monday...the aforementioned 500 mb low plunges 
far south into the southern tip of Baja California California before it 
begins to shift northeast. Both models are now taking the center 
of the low through central Mexico and passing directly overhead of 
Brownsville. The European model (ecmwf) is a bit faster with this translation but 
both models are finally in agreement with the overall path the low 
will take. This should keep the outlook for the middle of next 
week dry so backed off pop chances for day 7 and beyond.
