NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
646 am CDT Thursday may 5 2016 


Update... 
please see the 12z aviation forecast discussion below. 


&& 


Aviation... 
VFR conditions are expected at area taf sites through the current 
forecast period. Mainly light and variable or light northwesterly 
winds will continue this morning. Winds will then transition to a 
more northeasterly direction at or below 10kts along the I-35 
corridor by early afternoon. Farther west...winds will become 
southeasterly at kdrt around 15z. Mostly clear skies are expected 
as some thin cirrus clouds drift in from the west. 


&& 


Previous discussion... /issued 353 am CDT Thursday may 5 2016/ 


Short term (today through friday)... 


High amplitude ridging over the central US with deep upper troughs 
impacting the east and west coasts will leave south central Texas 
with more seasonal weather with wide diurnal temperature ranges. 
Light east/NE winds will continue to recirculate dry Continental air 
with good afternoon mixing into the dry layers aloft. Near 
persistence highs are expected for today and Friday...as southerly 
low level winds develop and increase during the day Friday. With 
the dry air...at least one more night of mins below normals is 
expected. 


Long term (friday night through wednesday)... 


Although surface winds return to southerly and increase 
slightly...dew points are expected to be slow to respond...and 
another night of near or below normal min temperatures is expected for 
Saturday morning with only a few morning clouds expected around 
daybreak. Middle and high level clouds will begin to invade western 
counties as the upper ridge is nudged slightly east by the western 
US upper low. Favor the GFS over NAM on a slower return of precipitable water 
values...and will remain conservative for probability of precipitation Saturday with only 
western Val Verde County showing a mention of weather. 


By Saturday evening...the all models show a significant breakdown 
of the middle to upper level ridge and a middle-level moisture tap 
connected to the inter-tropical convergence zone which is currently active between 110 and 
130w. For this reason...the probability of precipitation/weather for Saturday night through 
daytime Monday lean slightly to the wet side of blended guidance. 
As with most storms forming diurnally near the serranias del 
burros in the month of may...there is always at least a cape- 
related low end threat for severe weather...and the Storm Prediction Center outlooks 
currently detail threats into Monday morning over generally the northwest 
half of our area. A few strong storms could remain possible into 
early Monday evening as the rain focus shifts east into the I-35 
corridor and coastal prairies. There could be a dryline focus or 
there could be dry-slotting to cap most of the area...so the 
Monday pop and weather grid is at or below the inherited forecasts... 
meaning decreased confidence. Will handle the hazard threat here 
as vaguely as possible. 3 GFS runs in a row have trended with a 
more distinct dryline intrusion into central Texas...so the increased 
stability and hot temperatures out west is followed with slightly better 
confidence. 


Am cautious about buying into the stable pattern depicted going 
into Tuesday/Tuesday night...as large upper lows can carry 
subtleties that throw off models into yo-yo forecasting. Will also 
stay slightly on the wet side of the blended guidances in this 
period for one more forecast package. 


Nevertheless...the work week trend in probability of precipitation is down over 
wednesdays forecast package...but conditional instability will 
remain in play all week. Broad troughing remains depicted over northwest 
Mexico through Wednesday...and the more dynamic portion of the western 
US low is still a threat to bring a weak cold front into south 
central Texas next Friday.
