Area Forecast Discussion
National Weather Service San Angelo TX
1251 AM CDT Tue May 22 2018

.AVIATION...
/06Z TAFS/

Stratus is expected to spread north across the terminals
towards daybreak, with MVFR ceilings developing. Stratus will
linger through the morning hours, before scattering/lifting
to VFR by early afternoon. Could see some showers approach
the KSJT and KSOA terminals from the west during the early
to mid morning time frame but confidence is too low to mention
at this time. Expect light winds the next 24 hours.

AVIATION...
/00Z TAFS/

Look for challenging flight weather to develop again tonight.
Stratus will again develop later tonight and create MVFR ceilings,
at all terminals. Fog formation does not look as likely tonight,
thus, terminals this cycle do not include any fog. Expect return
to VFR conditions by 18Z Tuesday.

SHORT TERM...
(Tonight through Tuesday)

Visible satellite imagery indicates scattered cumulus across West
Central Texas this afternoon, with temperatures currently in the
upper 70s to low 80s across the region. The dry-line is currently
far west of the area (into western New Mexico) while an upper level
trough is over southern California/Nevada. An embedded short-wave
trough will move up in the southwest flow aloft today and spark
thunderstorm activity along and ahead of the dry-line in far West
Texas as the dry-line migrates back east. There is a slight chance
that some of these storms could drift far enough east to make it
into our western counties overnight tonight into early Tuesday
morning. Other than that, expect low clouds to surge back into the
area from the southeast late this evening through sunrise
Tuesday, with forecast overnight lows in the mid 60s.

We`ll see warming on Tuesday as an upper level ridge starts to
build. Highs Tuesday are forecast to reach the upper 80s. The dry-
line will be over the Permian Basin Tuesday and another short-wave
trough aloft will likely initiate more thunderstorm activity along
and ahead of the dry-line, with the slight chance once again that
some storms could develop into our western counties. Otherwise,
expect low clouds to mostly clear during the late morning, leaving
partly cloudy skies for the rest of the day.

LONG TERM...
(Wednesday through Tuesday)

A disturbance is expected to sit across the southwestern U.S. for
the first part of the period. This will allow for low rain
chances across the far western portions of the area. Then, a high
pressure ridge builds across the region allowing for higher
temperatures and dry conditions to persist through the remainder
of the work week. Highs looks to be above normal in the 90s.
Memorial day weekend looks to be hot in the mid 90s with minimal
chances for rain.
