...New Long Term...

.SHORT TERM... /Issued 1235 AM CDT Sun May 19 2024/
/Tonight through Sunday night/

The upper ridge currently over the Central and Southern Plains
will shift eastward over the next 24 hours while a broader trough
in the northern branch of the jet stream translates across the
western CONUS. This upper pattern will allow for a surface trough
to develop lee of the Central Rockies. The resultant pressure
gradient will bring an increase in southerly winds to the region
along with a constant fetch of Gulf moisture. The moisture surge
will keep overnight lows warm (upper 60s to lower 70s) and bring
early morning low clouds and patchy fog to parts of Central Texas.
The moisture return will be a bit deeper than it was Saturday
morning so it may take until mid to late morning before low
clouds/fog lift and dissipate. Ample afternoon sun and low level
warm advection will make for a hot, breezy, and humid afternoon
Sunday with highs in the upper 80s to lower 90s and afternoon heat
index values generally in the middle 90s. Warm and humid weather
will continue Sunday night with lows in the upper 60s to lower 70s
once again. Wind speeds Sunday night will be strong enough to
limit fog production.

.LONG TERM... /NEW/
/Monday through Saturday/

The work week will start out hot, rain-free, and humid due to low
level warm advection and ridging aloft. Highs Monday and Tuesday
will range from the upper 80s in the east to the middle 90s in the
west. Lows will be in the upper 60s to the lower 70s.

The upper ridge axis will shift to the east Tuesday in response
to a trough approaching from the west. Although large scale
forcing for ascent will gradually increase, it will likely not be
strong enough to eliminate a cap of warm air aloft. Therefore, no
measurable rainfall or thunderstorms are expected on Tuesday, but
a few storms developing along and just ahead of an approaching
cold front may manage to cross the Red River Tuesday night. Storm
chances will increase Wednesday when the front moves into North
Texas and a shortwave moves quickly through southwest flow aloft.
The front is progged to move a bit farther south Wednesday night,
but it may get a push farther south depending on the extent of
cool convective outflows that may develop during the day. Lift
along the front and passage of additional shortwaves will warrant
chance PoPs Wednesday night with slightly higher PoPs Thursday due
to the arrival of stronger shortwave energy and the return of the
front back to the north. It is difficult to say exactly where and
how much rain will fall, but the setup has the potential to
produce locally heavy rainfall which may result in some flooding.
Instability and wind shear are also progged to be sufficient for
some strong to severe storms, especially Thursday afternoon.
Rain/storm chances will temporarily end on Friday but the passage
of additional shortwaves embedded in southwest flow may spark a
few storms Friday night.

Temperatures the second half of the week will be slightly cooler
due to more clouds, showers/storms, and the brief appearance of
the cold front. Highs Wednesday and Thursday will be generally in
the 80s to around 90. Lows Wednesday night will range from the
middle 60s near the Red River to the lower 70s across Central
Texas. A slight warmup is expected Friday and Saturday with highs
in the upper 80s and 90s and lows from the upper 60s to the lower
70s.

.AVIATION... /Issued 1235 AM CDT Sun May 19 2024/
/06Z TAFs/

The only aviation weather concern will be the potential for
stratus and patchy fog across Central Texas early Sunday morning.
A 30 knot low level jet, as indicated by the KFWS VAD wind
profile, will lift moisture over the higher terrain of the Texas
Hill Country, resulting in a deck of stratus initially between
1000 and 2000 ft. The base of the low cloud deck will temporarily
lower below 1000 ft around sunrise, briefly impacting the Waco
terminal, but likely remaining south/southwest of D10. Ceilings
in Waco will lift through the morning, scattering out by midday.
Temporary visibility restrictions between 2 and 4 miles will
accompany the low clouds, but these will also improve above 6
miles in the mid to late morning.

Otherwise, VFR conditions are expected Sunday and Sunday night
with a south wind in the 6 to 10 knot range tonight and 10 to 16
knot range on Sunday along with some daytime gusts near 20 knots.
