Area Forecast Discussion
National Weather Service Corpus Christi TX
1030 PM CST Sun Jan 31 2021
.AVIATION...
VFR and light northerly winds will continue through Monday as
broad high pressure moves closer.
&&
.PREV DISCUSSION... /Issued 307 PM CST Sun Jan 31 2021/
SHORT TERM (Tonight through Monday Night)...
This morning's cold front is well south of the area and is currently
pushing towards the Central Gulf. Much drier air has been filtering
into the region behind the boundary. PWATs are hovering around 0.5"
per the GOES16 TPW imagery. Despite the passage of the front this
morning, temperatures have warmed into the upper 70s to low 80s.
Breezy northerly winds will continue through the afternoon before
weakening overnight. Light winds and sufficient radiational
cooling will allow for temps to fall into the upper 30s to mid
40s. Highs will be a bit cooler tomorrow as CAA continues with
temps in the upper 60s to near 70 degrees. Northerly winds will
begin to shift to the east-northeast Monday night as the surface
high nudges east.
LONG TERM (Tuesday through Sunday)...
Surface high pressure ridge will be translating to the east on
Tuesday with highs near normal. An upper level ridge over northern
Mexico Tuesday and Wednesday will dampen out as it drifts across the
region by Thursday. Warming trend will occur through Wednesday and
Thursday with readings in the 80s across the region Thursday except
for the immediate coast. Low pressure will be over the southern
plains Thursday leading to breezy conditions over the Coastal Bend.
Most of the medium range models, except for the GFS, are more
progressive with the upper trough moving from the Rockies Wednesday
night into the plains Thursday. This should send the next cold front
into the area early Friday. Only limited moisture return expected
but will keep a mention of slight chance of showers along the coast
into the coastal waters Friday. High pressure behind this front will
be weak with temperatures expected to only cool to near normal by
Saturday.
Medium range models are in agreement with a strong upper ridge
building north into the Gulf of Alaska by the weekend. Arctic air
mass will be building over northwest Canada by Friday. This arctic
air mass will surge into the central plains Saturday morning as a
short wave trough dives southeast into the central plains. Expect
this modified arctic air mass will reach south Texas by early Sunday
morning. Went with CONSAll for winds/temperatures this period which
was similar to the ECMWF/CAN models.
MARINE...
Moderate to strong offshore flow will continue through tomorrow
morning. The Small Craft Advisory remains in effect through 6 AM
but may need to be extended by a couple of hours. Winds will
begin to weaken by mid morning as the pressure gradient relaxes.
A weak to moderate offshore flow is expected tomorrow afternoon
through the overnight hours. Winds will begin to shift to the
northeast as we head into Tuesday morning. A weak onshore flow
will develop Tuesday as high pressure shifts to the east. The weak
to moderate onshore flow will continue through Wednesday morning.
The onshore flow will strengthen Wednesday afternoon and become
moderate to strong Wednesday night as low pressure forms over the
southern plains. SCA conditions are expected over the Gulf waters
Wednesday night through Thursday night as winds remain moderate to
strong. Winds will shift to weak to moderate offshore behind a
cold front Friday morning and continue through Friday evening.
Isolated showers will be possible with the front Friday. A brief
period of onshore flow will occur Saturday before the next cold
front with modified arctic air forecast to reach the coastal
waters by early Sunday morning. Strong offshore flow/SCA will
occur behind this cold front Sunday.
