.SHORT TERM (Tonight through Wednesday Night)...

Hot conditions are in place for the rest of today with temperatures
in the mid to upper 80s to the lower 90s as of 2:30 PM. There is a
good chance for record highs across all climate sites for today. See
climate section below. Otherwise, plenty of sunshine is expected
across most areas with south to southwest winds around 10 mph with
gusts up to 25 mph. A dryline is making its way across Val Verde and
Edwards Counties and expected to move eastward through late this
afternoon. Surface observations are showing very dry air across the
Hill Country with dewpoints in the 30s and relative humidities in the
teens as a result of a well mixed atmosphere. All of this translates
to fire weather concerns across the Hill Country southwestward to the
Rio Grande where a Red Flag Warning is in effect through 8 PM this
evening. Fire weather concerns continue into Wednesday for most areas
and another Red Flag Warning has been issued from 10 AM through 8 PM
Wednesday for all areas except Lee, Fayette and Lavaca Counties due
to breezy northerly winds and low relative humidity.

Another weather concern for the rest of today across the southwest
and southern counties of South Central Texas is the possibility of
isolated strong to severe thunderstorms as an upper level trough axis
moves into the east Texas coast. Main hazards will be damaging winds
and large hail. All hires models agree for convection to begin over
Mexico and then push to the east and southeast through early this
evening. The shower and thunderstorm activity comes to an end between
7 and 8 pm across the southern areas with mostly clear skies for all
areas overnight.

A strong cold front is forecast to push across the area early
Wednesday morning with breezy and cooler temperatures. Wednesday’s
high temperatures are expected to range from the mid 70s across the
Hill Country to lower 90s across the southwest.  As mentioned
earlier, a Red Flag Warning is in effect for Wednesday for all areas
except east of Highway 77 from 10 AM to 8 PM. Cooler temperatures are
in store for Wednesday night with lows in the 40s and 50s.

&&

.LONG TERM (Thursday through Tuesday)...

Beautiful spring weather is expected across South-Central Texas for
the end of the workweek and into the start of the upcoming weekend
with low humidity and some cool mornings and mild but not too hot
afternoons. The coolest morning will be during Friday morning where
the low-lying valleys across the hill Country could fall into the
mid 30s. The warmest day will be on Saturday with the afternoon
highs in the mid to upper 80s. Fire weather concerns remain through
this period given the dry airmass and the very dry fuels. Highest
fire weather danger would be Thursday afternoon given a moderate to
breezy northwesterly flow over the region behind a large upper level
low over the Great Lakes. Winds are lightest on Friday as surface
high pressure is more positioned overhead. Saturday then returns to
a breezy southerly flow as surface high pressure slides towards the
east. Despite the southerly winds, the fire weather concerns will
linger at least through Saturday afternoon as the moisture recovery
takes some time.

The pattern will become a bit more active from Sunday through early
next week as longwave troughing establishes across the western CONUS
while occasional embedded shortwaves in the southwesterly flow aloft
advance out of Mexico and into the region. This will likely result
in several opportunities for isolated to scattered convection across
the region with help from any additional lifting mechanisms, such as
the dryline and/or outflow. Enough ingredients may coexist at times
to allow for more organized convection to develop where storms could
trend towards strong to severe levels at times. Otherwise, expect a
warmer and more humid stretch of weather with moderate to breezy
southeasterly winds and more cloud cover.

.FIRE WEATHER...

Elevated to critical fire weather conditions expected today and
continue through Saturday. Minimum humidities will plunge into the
single digits and 10s across our western areas this afternoon and
Wednesday across most areas. Fire weather concerns continue
through at least Saturday. Red Flag Warning is in effect for the
Hill Country and Rio Grande through 8 PM this evening. Another Red
Flag Warning is in effect for all areas except Lee, Fayette and
Lavaca Counties on Wednesday. Additional Red Flag Warnings are
expected for the next several days. Fuels are expected to remain
dry through the weekend.
