.SHORT TERM... /NEW/
Update:
No major changes were made to this morning's forecast. The main
changes were to expand the mention of thunder further north into
the rest of North and Central through the morning hours.
With the frontal boundary still just south of our CWA, the
expectation is that much of the severe weather will remain south
of our area. That being said, there remains plenty of instability
along with steep mid-level lapse rates, allowing for small hail to
remain the main threat. Can't rule out gusty winds as well, but
given the elevated nature of these storms, damaging winds appear
unlikely at this time.
Winds this morning have begun to increase areawide, gusting to
around 30 mph in some locations. This is expected to be the case
through much of the morning hours and into the afternoon as the
main weather system moves overhead.
Precipitation is expected to diminish late today as the shortwave
keeps tracking to the east. Winds will likely diminish after
sunset, leaving behind partly cloudy skies with lows in the 40s
across the region.

Previous Discussion:
/Through Tonight/
Widespread precipitation has begun to develop across the western half
of the state as anticipated, with showers ongoing across the Brazos
Valley at the moment. The culprit for today's precipitation will
be the combination of a stalled front across Central Texas coupled
with an approaching shortwave currently centered between Big Bend
National Park and El Paso.
Gradual eastward movement through the night will enhance the
development of additional showers and thunderstorms through much
of the heart of Texas, then gradually advance eastward this early
morning. As showers and thunderstorms increase in coverage and
spread eastward, there will be a potential for at least some small
hail from any storm across Central Texas. Instability and lapse
rates significantly drop off the farther north you go, with very
little opportunity for hail across North Texas.
The location and threats of severe weather will remain highly
dependent on the placement of the warm front. With the wind field
responding to the strong southerly flow ahead of the incoming
shortwave, it is possible this warm front makes a gradual
northward push into our southern tier of counties, mainly from
Bell to Leon Counties and points south. If a storm is able to
develop in the warm sector, the probability for large hail would
increase. At this point, it appears unlikely that the warm sector
will actually reach our CWA given the development of a surface low
appears to occur just southwest of the Temple/Killeen area, then
move to the southeast through the day. Although unlikely at this
time, if the warm sector does move into the the Bell to Leon
County area, there would be a temporary increase in the threat of
large hail, damaging winds, and can’t rule out an isolated
tornado given the strong low-level wind shear. Again, the threat
for damaging winds and tornadoes will remain near zero if the warm
front remains south of our region. The threat of severe weather
is expected to decrease through the late morning hours, and by
noon today, any severe weather potential will have moved out of
the region.
The other threat that will arise as precipitation invades North
and Central Texas will be that of flooding. Minor flooding of
roads will be possible as recent rainfall, combined with dormant
vegetation, will enhance runoff. A widespread area of 1 to 2
inches appears likely south of the Interstate 20 corridor.
Additionally, up to 3 inches would be possible across the Hill
Country. Prolonged heavy precipitation may lead to flooding of
roads this early morning and continue through the day tomorrow.
Therefore, if you encounter a flooded road, Turn Around, Don’t
Drown!
The bulk of the precipitation is expected to move eastward
through the late afternoon and evening hours as the shortwave
moves away from the region. Wind speeds are likely going to
increase throughout the morning as a tightening pressure gradient
translates to strong northeasterly winds. Winds could gusts as
high as 35 mph, but sustained winds will likely remain at to
slightly below 25 mph. Winds and precipitation will decrease
tonight, leading to a drying trend from west to east after
midnight.
With plenty of precipitation and cloud cover in place today,
highs will likely remain in the 50s for much of the region. With
the blustery northeasterly winds in place, it will feel about 10
to 15 degrees cooler than the actual temperature. Therefore, if
you are planning on venturing out today, make sure to prepare for
the chilly wind chills as well as the expected precipitation. Lows
tonight will dip into the 30s and 40s as a gradual clearing trend
commences from northwest to southeast.

.LONG TERM... /Issued 202 AM CST Wed Mar 4 2020/
/Thursday through Tuesday/
Rain will move east of the region by sunrise Thursday as the
upper low opens up and lifts to the Mississippi Valley. Increasing
large scale subsidence will result in a clearing sky. Although
weak cold/dry air advection will remain through the day, temperatures
should still warm into the 60s. However, the dry air and clear
sky will help temperatures to fall steadily after sunset with
lows from the upper 30s to the mid 40s.
Ridging aloft and dry air near the surface will make for a beautiful
end to the week with abundant sun, a relatively light wind and
near normal temperatures both Friday and Saturday.
The upper ridge axis will move east of the region Saturday night
in response to a developing trough on the West Coast. This upper
pattern will result in a deepening lee trough across the Northern
and Central High Plains and the return of Gulf Moisture back to
the Southern Plains. Therefore, it will be mostly cloudy, more
humid, breezy, and mild Sunday and Monday with highs mainly in the
60s Sunday and 70s Monday. There will also be a chance for
showers and isolated thunderstorms Sunday and Monday as shortwave
energy embedded in southwest flow aloft moves across the region.
The upper flow will become more zonal Tuesday, but mild
temperatures and low rain chances will linger. Temperatures
Tuesday will remain above seasonal normals with highs in the lower
and middle 70s and lows in the 50s. It does appear that a cool
down will occur around the middle of next week with the passage of
a cold front.

.AVIATION... /NEW/
/12Z TAFs/
Convection is ongoing across North and Central Texas as the main
upper level shortwave makes its way into the region. Given the
convective trends, there remains a mention of thunderstorms at all
North Texas airports until 14Z. After 14Z, expected rain to
continue sans lightning.
The ceiling forecast remains tricky given the sharp gradient in
low-level moisture on the north side of the surface low. For now,
have sided with the more optimistic forecast, keeping North Texas
MVFR through sunset tonight. This will be reevaluated in case IFR
looks more likely. For Waco, IFR is ongoing and expected to remain
in place through the rest of the morning. As the rain begins to
dissipate, MVFR will likely take over KACT and remain through the
rest of the day.
In addition to the ongoing precipitation, winds have begun to
increase, generally gusting to around 25 kts. They are expected to
remain quite breezy through the rest of today. Given the
orientation of the winds, moderate crosswind issues will be
possible on all northwest to southeast oriented runways.
