Area Forecast Discussion...UPDATED
National Weather Service Corpus Christi TX
1051 PM CST Sun Jan 17 2021

.AVIATION...A light onshore flow over the Coastal Bend has
brought higher surface moisture inland with dewpoint temps
in the lower 50s. This higher boundary layer moisture will
continue to move inland into the Brush Country tonight. Expect
radiational fog/MVFR vsbys to form over the southern Brush Country
into the Coastal Bend by 09Z, and then deteriorate to LIFR by 11Z
with low stratus/fog moving north into the northern Brush Country
between 12-13Z. The Victoria Crossroads will be a little drier,
so only expecting MVFR vsbys with IFR vsbys possible from 12Z-16Z.
The fog will continue over the rest of south Texas until around
16Z with improvement to IFR ceilings/MVFR vsbys between 16Z-18Z.
MVFR ceilings will linger over the coastal plains late Monday
morning. Southerly winds will become gusty Monday afternoon with
VFR conditions area wide. Low level flow will increase on
Monday night and bring in MVFR ceilings to the inland coastal
plains to the eastern Brush Country by late evening.

&&

.PREV DISCUSSION... /Issued 946 PM CST Sun Jan 17 2021/

DISCUSSION...Light southeast flow has pushed higher surface
moisture inland with dewpoint temperatures in the upper 40s to
lower 50s from the Brush Country to the Coastal Bend. Expect
radiational fog to form over the northern portions of deep
south Texas late tonight that will move northward into the
Brush Country and Coastal Bend. Latest HRRR model along with
SREF probabilities give more confidence that fog may become
dense over these areas.

PREV DISCUSSION... /Issued 402 PM CST Sun Jan 17 2021/

SHORT TERM (Tonight through Monday Night)...

Deterministic runs move an upper trough/low across the Midwest/ERN
CONUS while a series of upper disturbances result in the
development of a mean upper trough over the WRN CONUS/Baja CA
during the period. The LFQ of an upper jet streak is predicted to
approach/enter the CWA Monday night. Increasing onshore
flow/moisture expected over the CWA/MSA, with PWAT values
near/above normal over the ERN CWA Monday night (per NAM/GFS.)
Anticipate that increasing upper forcing and moisture will
contribute to isolated showers over the ERN CWA Monday night. NAM
deterministic output/SREF probabilistic output suggest that fog
may occur over the inland CWA tonight/early Monday morning.

LONG TERM (Tuesday through Sunday)...

A surface low pressure located over Mexico Monday will approach the
area Tuesday and Wednesday. With onshore flow and the low pressure
to the west, WAA and moisture will continue to being pumped into
South Texas. A cold front is expected to attempt to push through
South Texas mid week, but appears like it will wash out just north
of our area. With PWATs expected to be near 1.5 inches or higher
Tuesday through the end of the week, which is in the 99th percentile
for this time of the year. With the approaching disturbance and near
record PWATs, isolated to scattered showers will be possible Tuesday
through Wednesday night with a slight chance of thunderstorms. Rain
chances are expected to taper off Thursday morning, however, due to
elevated PWAT values, mainly across the Coastal Bend, left enough
PoPs for slight chance of showers through the end of the work week.
Models are showing the possibility our next cold front sometime this
weekend, however, due to model disagreement the timing of the
front is still up in the air.

With the increase in cloud cover and possible showers Tuesday and
Wednesday, highs are expected to remain cool with temperatures
ranging in the lower to upper 70s. With onshore flow continuing and
cloud cover clearing up, temperatures are expected to warm into the
upper 70s and lower 80s across much of the area Thursday through
Saturday. Low temperatures are expected to remain mild in the lower
to mid 60s Tuesday night through Saturday.

MARINE...

In response to the development of upper level disturbances to the
west, increasing onshore flow and moisture expected during the
period. An upper level jet and significant moisture may result in
isolated showers Monday night. Small Craft Exercise Caution
conditions expected over the coastal waters Monday, with Small
Craft Advisory conditions over the offshore coastal waters Monday
night. A moderate to strong onshore flow will be in place until
Tuesday night, then becoming weak to moderate for the remainder of
the week. Small Craft Advisory conditions remain a possibility
through Tuesday night due to seas up to 7 feet, and possibly
returning next weekend. In the meantime, Small Craft Exercise
Caution conditions will be likely Wednesday through Friday night.
Rain chances will increase Tuesday through Thursday as a
disturbance approaches the area with a slight chance of
thunderstorms Tuesday and Tuesday night.
