Area Forecast Discussion

1128 AM CST Sat Dec 18 2021
.AVIATION...
Cold front just NW of VCT will continue sweeping S this afternoon
ahead of gusty N winds and low CIGs. Widespread +TSRA are most
likely at VCT with the potential for some hail, before this
activity shifts mostly offshore later today. Farther SW along the
front, still feel that some TS will threaten CRP during FROPA
around 21z. Precip should taper from N-S following FROPA with
most areas dry this evening with VFR ceilings west and mostly MVFR
for the eastern terminals. Potential for some -RA tomorrow
morning is too iffy at the moment for inclusion in this TAF cycle,
but after 18z Sunday this should change.
&&
.PREV DISCUSSION... /Issued 956 AM CST Sat Dec 18 2021/
DISCUSSION...
Quick update this morning to align PoPs more closely to observed
trends and to boost winds speeds a bit more behind FROPA this
afternoon. This front as of 930 AM stretched from SAT west to near
DRT and was moving south around 20 knots. On this pace, FROPA
looks to occur at VCT around 1 PM and CRP ~3 PM which aligns well
with the latest HRRR and NAM. Prospects for severe storms are
perking up a bit more, especially over the northern Coastal Bend
and Victoria Crossroads where a N-S axis of exceptionally rich
PWATs (1.6") resides with MLCAPEs AOA 2000 J/kg. Compared to
points farther W-SW, this deeper boundary layer moisture and
subsequent weaker capping is convecting more easily and should
result in the greatest coverage of storms focusing NE of CRP
through the day. The concern for CRP and the rest of the Coastal
Plains is that 850mb winds have veered more SW since the 12z RAOB
and increased to 20 knots which may unfortunately advect lower
PWATs/more CIN along our southern coast by the time FROPA occurs
this afternoon. This is evident in the latest HREF which shows
diminished storm coverage this afternoon near CRP, although our
PoPs over the southern coastal counties remain 60-70% given such
favorable ascent on the horizon, with 90% PoPs farther northeast
closer to the moist axis. No other updates at this time.
