Area Forecast Discussion

.AVIATION... /06Z TAFS/

No low clouds are expected near the 4 TAF VCNTYs. CONSSHORT
indicates a possible area of low clouds and fog forming around Cuero
and perhaps as far north as La Grange, but southwest winds in the
boundary layer are already enhancing a topographic drainage wind out
of the W/NW to prevent a rise in dewpoints. The gradient is somewhat
tight just east of the I-35 Terminals, so the wind directions will be
important to maintain despite the low speeds through 12Z. Will keep
a dry forecast in place with mostly clear skies. Westerly wind
components increase after 15Z and should keep skies mostly clear
across the forecast area by midday.

.PREV DISCUSSION... /ISSUED 244 PM CST Thu Dec 12 2019/

SHORT TERM (Tonight through Friday Night)...
A clear night is in store for the tonight period. Some clouds are
expected to redevelop across the coastal plains and over the far
east portion of the area overnight. Those similar locations may end
up with patchy fog due to elevated dewpoint temperatures. Otherwise,
a much warmer morning commute with lows in the 40s. Clearing will
take place in the late morning continuing through the afternoon with
high temperatures in the mid to upper 70s.

A reflection of a mid to upper level disturbance moving across the
area to show at the surface with west to northwest winds on Friday.
By early Friday evening, a weak frontal passage is forecast to push
across the area, keeping a similar wind flow, but not for long. A
surface high pressure system builds across the upper Texas coast with
a southeast flow expected for Saturday.

LONG TERM (Saturday through Thursday)...
With the return of a southerly wind flow and limited moisture in
place, expect pleasant weather conditions on Saturday with highs in
the 70s for the most parts. Dry conditions continue on Sunday with
increased moisture which means warmer temperatures for the area with
highs in the upper 70s and lower 80s.

Next rain chances come on Monday of next week as a cold front move
across the area. However, at this time, the forecast calls for
scattered showers and isolated thunderstorms for areas along and
east of Interstate 35. Rainfall accumulations will be limited if
this forecast holds with amounts less than one tenth of an inch for
affected locations.

The front looks to quickly exit the area with a cold and dry airmass
behind it. Overnight lows on Tuesday are expected to range from the
lower 30s across the Hill Country to upper 30s along the I-35
corridor. A colder night is forecast for Wednesday morning with lows
in the 20s across the Hill Country to lower 30s elsewhere. High
temperatures on Tuesday and Wednesday afternoons in the 50s. Back to
the 60s on Thursday as moisture increases.
