NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
1244 PM CDT Thursday Apr 24 2014 


Aviation... 
/18z tafs/ 
clearing is taking place across the western half of south central 
Texas early this afternoon. MVFR ceilings will affect only kssf maybe 
from 18z to 19z as a dry-line/weak frontal boundary pushes across 
the area. A wind shift from northwest to north and NE is expected across the 
I-35 sites between 21z and 22z this afternoon as the boundary 
travels southeastward. Wind speeds will be around 10 knots most 
areas with gusts up to 20 knots...especially over the Rio Grande 
plains. The boundary weakens as it approaches the coastal plains 
later tonight. East to southeast winds are anticipated to return 
on Friday. VFR conditions are expected across the area terminals 
for much of this forecast cycle.

Previous discussion... /issued 633 am CDT Thursday Apr 24 2014/ 


Aviation... 
low level southeasterly winds bringing moisture and MVFR ceilings to 
south central Texas this morning. Expect clouds to lift by 17z 
most areas with VFR expected for the trest of the taf forecast 
period. A weak cold front was located over West Texas from near 
Throckmorton to Big Spring at 11z. This boundary should slide 
southward through the day...reaching the Austin/San Antonio area 
around 21-23 z before washing out further to the south. Could see 
an isolated storm along the front this afternoon...but confidence 
is very low so will not include in tafs. Otherwise...wind shift to 
the northeast and drier air movig in this evening should hamper 
low cloud development overnight. 


Previous discussion... /issued 339 am CDT Thursday Apr 24 2014/ 


Short term (today through friday)... 
mostly cloudy and humid conditions this morning will dissipate 
from west to east today from a Pacific front. A few light showers 
will be possible over central Texas this morning with possibly enough 
focus for isolated thunderstorms east of I-35 in the afternoon. 
Stability through decreasing moisture availability should prevent 
the storms from becoming organized and limit the potential for 
severe weather although lapse rates would be sufficient for strong 
storms should the moist layer be slow to decrease. Increasing 
trends on the drying potential with the more recent model runs 
could suggest that no storms form at all. Shallow low level 
moisture is expected to hold over the coastal Bend to allow for 
areas of fog to form around daybreak Friday. Then east/NE low level 
winds will resume drying for a mostly sunny...arid and warm day 
Friday. 


Long term (friday night through wednesday)... 
onshore flow increases Friday evening...and a quick return of 
humidity brings low clouds and possibly some light rain showers or 
patchy drizzle by Saturday morning. A deepening upper trough to 
the west could enhance this lift to produce some light measurable 
rainfall amounts along the Escarpment by midday. Late in the 
day...isolated thunderstorms are possible near the Rio 
Grande...but will expect a cap to keep most of the activity in 
Mexico until the early evening. Steepening lapse rates and 
increasing wind shear could promote a few severe storms as noted 
by the day 3 slight risk area extending into The Hill Country. 
Rain chances remain higher over North Texas and a dry slot could 
lower rain chances for most areas by Sunday morning. Downsloping 
westerly winds Sunday afternoon could produce the warmest 
temperatures so far this season...especially west of San Antonio. 
The upper low is expected to deepen over the Central Plains and 
be slow to eject eastward...leaving a similar breezy and warm day 
for Monday. Late Monday the cold air advection is expected to 
increase with mild and dry weather to last into late next week. 


Fire weather... 
strengthening trends in the Pacific front for today will result in 
elevated fire weather conditions for The Hill Country...southern 
Edwards Plateau...and northern Rio Grande plains. The next 
elevated fire weather pattern is expected for Sunday and 
Monday...with near critical fire weather conditions possible west 
of I-35.
