Area Forecast Discussion
National Weather Service Corpus Christi TX
1226 PM CDT Sat May 21 2022
.AVIATION...
VFR conditions are expected to prevail today with gusty winds
before dropping back into MVFR tonight. Showers and thunderstorms
are possible at all sites tonight as a front approaches the
region. Showers and thunderstorms could begin as early as 04-06z
across COT and LRD, 05-07z across VCT and 10-14z across ALI and
CRP. As the front moves across the area, winds are expected to
shift to the east between 05-08z.

.PREV DISCUSSION... /Issued 709 AM CDT Sat May 21 2022/
AVIATION...
A mixture of MVFR/VFR conditions is ongoing across area terminals,
with MVFR cigs across CRP/VCT and VFR out west. A gradual return
to VFR is expected around mid morning, before MVFR conditions
develop once again this evening as a frontal boundary approaches
the region from the north. Vicinity showers and thunderstorms will
be possible ahead and along the boundary late tonight into early
Sunday morning. Winds will be gusty out of the south and
southeast around 20-25 kts through this evening. As the front
nears the region tonight, winds are expected to lighten up and
shift eastward.
PREV DISCUSSION... /Issued 449 AM CDT Sat May 21 2022/
SHORT TERM (Today through Sunday)...
The thunderstorm activity associated to a passing mid level
disturbance across the region earlier in the night as finally
cleared out of the area, and a slightly drier and more stable
airmass has settled in.
Rain chances will remain limited across the area through most of the
day today as weak ridging at the 500 mb level builds in. By this
afternoon, however, the forecast becomes more unsettled as a trough
crossing the Northern Plains sends a late season cold front across
the state. This boundary is progged to approach the northern parts
of the CWA late tonight into early Sunday morning, before probably
stalling as it nears the coast by the mid to late morning hours.
Increased convergence ahead and along the boundary, in addition to a
steady increase in Gulf moisture over the region (PWATs 1.8-1.9")
and a moderately to highly unstable airmass (SBCAPE ~2500-4000 J/kg)
with little to no convective inhibition, will provide the setting
for some strong to potentially isolated severe thunderstorms to
develop and push through the region overnight. Latest CAM models
indicate a line of thunderstorms developing over the Southern
Plains tonight with the southern tip extending into portions of
the northern CWA by early Sunday morning. Day 1 convective outlook
from SPC has maintained northwestern portions of the Brush
Country under a marginal risk for severe weather tonight. Rain
and storm chances are expected to linger onto Sunday as the
boundary stalls.
Hot temperatures and dangerous heat indices are in store for South
Texas today, with temperatures ranging from the upper 80s along
the coast to around 105 out west. A Heat Advisory is in effect
from noon through 7 PM today across the inland Coastal Plains,
Brush Country and Rio Grande Plains. Heat indices may exceed 110
degrees over the area under Advisory and may range between 105 to
109 degrees elsewhere. The temperature forecast for tonight and
Sunday will be dependent on how far south the front is able to
push through and the amount of cloud cover. But, in general,
expect overnight lows in the 70s, with highs on Sunday ranging
from the upper 80s to the mid 90s.
In addition to the heat, a High Risk of Rip Currents will remain
in effect through at least Sunday morning owing to the combination
of a strong onshore flow and long period swells moving in.
LONG TERM (Sunday Night through Friday)...
Rain chances will be on the increase Monday as another in a series
of short wave troughs track across the region and taps into
deepening moisture and an unstable environment. Numerous showers and
thunderstorms are expected across the Rio Grande Plains, Brush
Country and Victoria Crossroads to scattered across the Coastal
Bend. PWATs start to approach 2 inches and the cap is fairly weak on
Monday. The only thing missing is a low level focus/boundary.
Although, the sea breeze and any outflow boundaries from storms
farther north could provide a focus for storms which strong storms
could develop along.
By Monday night, models develop an area of low level moisture
convergence as a strong mid level short wave trough tracks across S
TX. PWATs are progged to increase to 2.3 inches across northern
portions of the CWA with a moderately unstable environment still in
place, but CIN values are also progged to increase from the south.
Feel the other environmental factors will be strong enough to
overcome any weak capping inversion. Thus, TSRAs are expected to
become numerous across all of S TX Monday night. The GFS forecast
sounding also indicated a saturated profile with skinny CAPE across
the northern CWA late Monday night/early Tuesday morning which is
conducive for heavy rainfall. Given the lack of any significant
rainfall recently, am not expecting any widespread flooding.
However, localized flooding of low lying areas may be possible.
Scattered showers and thunderstorms remain possible through
Wednesday then decrease by Thursday as ridging builds across the
region and brings a weak frontal boundary across S TX. Models are in
pretty good agreement with a front moving through S TX, but differ
on timing and strength as well as when the rain chances diminish.
For now kept with the NBM which shows the boundary pushing through
Thursday with drier and slightly cooler conditions filtering into S
TX Thursday. But this will be brief as temps quickly warm up by
Friday.
Hot and humid conditions will persist through Wednesday. This will
lead to heat index values ranging from 100 to around 105 each
afternoon through mid week.
Minor coastal flood potential should decrease this upcoming weak as
astronomical tides decrease. However, the rip current risk may
remain at moderate to high Sunday night with swell periods
increasing to around 9 seconds.
MARINE...
Strong southeasterly flow and Small Craft Advisory conditions are
expected to continue through the mid morning hours today across
the bays and through early this afternoon over the Gulf waters.
Occasional gusts to gale force will be possible. The flow will
decrease to moderate to strong levels later this afternoon and
remain at these levels overnight. Winds will shift eastward on
Sunday and become weak to moderate as a frontal boundary
approaches the region. Isolated to scattered showers and
thunderstorms will be possible ahead and along the boundary
tonight through Sunday. Moderate to strong onshore flow is
expected Monday through Wednesday with flow becoming northeasterly
with the approach of a cold front mid to late next week. Advisory
conditions are expected Monday through Wednesday. Isolated to
scattered showers and thunderstorms are expected Monday through
Wednesday.
