.AVIATION...
Low clouds continue to linger over San Antonio and Austin. MVFR
ceilings will persist through the middle of the evening and then drop
to IFR. MVFR fog will develop overnight. Some models are suggesting
dense fog, but the visibility forecast doesn`t seem to match the
temperature and dew point forecasts. A cold front will move through
the region Sunday morning and will clear out the ceilings with
northwest to north wind.
At DRT, conditions will remain generally VFR, but there is a chance
for temporary IFR ceiling for a few hours late this evening and early
Sunday morning. Northwest winds will move in overnight.

.PREV DISCUSSION... /ISSUED 224 PM CST Sat Feb 16 2019/
SHORT TERM (Tonight through Sunday Night)...
This mornings cold frontal passage has left the area with an
interesting temperature gradient. Currently, for the counties in the
northeastern section area are seeing temperatures in the 40s, while
our furthest western county of Val Verde is already up to 81 degrees.
The cold air advection will stay limited to the northeast. This
evening, winds turn back to southeasterly and keep temperatures mild
overnight before another cold front passes through early tomorrow
morning. Most models showing frontal passage as dry until reaching
coastal region. The passage of this Pacific front will lower RHs into
the teens for Rio Grande Plains. These low RHs and increased winds
from FROPA will bring Elevated Fire Weather for areas west of I-35
Sunday afternoon.
LONG TERM (Monday through Saturday)...
Cooler airmass from Sunday`s frontal passage will set up another wet
pattern as isentropic ascent keeps the area cloudy and damp with
chances for rain from Tuesday through Wednesday. Temperatures also
remain cooler through Thursday. Thursday, another approaching system
brings more chances for showers, mostly for eastern counties. By
Friday, temperatures recover to near normal.
