Area Forecast Discussion
National Weather Service Corpus Christi TX
1233 AM CDT Mon Jun 7 2021

.AVIATION...06Z TAFs

The period will begin with predominately VFR ceilings, though have
included TEMPO groups for MVFR for all sites other than LRD.
Patchy fog may develop late tonight/early Monday morning, but winds
will become breezy to windy Monday morning limiting the time fog
could persist. VFR conditions will return by late morning for all
sites and should continue to the end of the period.

&&

.PREV DISCUSSION... /Issued 644 PM CDT Sun Jun 6 2021/

AVIATION...00Z TAFs

MVFR ceilings will continue to affect the northern Coastal Bend
into the Victoria Crossroads early this evening while VFR conditions
will exist elsewhere. The low level southerly flow will strengthen
to 30-40 knots tonight. Expect MVFR ceilings will move into the
southern Coastal Bend by 03Z and move inland during the rest of
the evening hours and reach as far west as a HBV-COT line by 09Z.
There will be the possibility of IFR ceilings/MVFR vsbys with
patchy fog at ALI before daybreak. Ceilings will lift over the
Brush Country and Coastal Bend by late morning while MVFR ceilings
will linger into early afternoon for VCT area before lifting to
VFR levels. South to southeast winds will become gusty over the
coastal plains by 14Z and continue through the afternoon with
gusts up to 30 knots possible at CRP.

PREV DISCUSSION... /Issued 409 PM CDT Sun Jun 6 2021/

SHORT TERM (Tonight through Monday Night)...

Concur with the deterministic runs that the upper low will
continue to lift slowly toward the E/NE during the period, with
subsidence over the CWA during the period. The NAM predicts
maximum CAPE values Monday afternoon, yet greater minimum CIN
values, and near normal PWAT values. CAPE/moisture
notwithstanding, expect subsidence/CIN to preclude convection.
Diurnal moderate/breezy onshore flow expected Monday. Maximum
Heat Index values Monday may reach 110F, yet will defer to the mid
shift for NPW issuance.

LONG TERM (Tuesday through Sunday)...

The long term starts out with a Mid-level low over the Midwest and a
High pressure over north central Mexico. This high will dominate our
weather pattern for the upcoming week and expect mainly dry and
hotter conditions to take hold. As the high pressure remains parked
over MX, any upper level disturbances will circumnavigate around it
and will travel north near the Canadian border.

Look for daily highs mainly range between upper 80s near the coast
with low 100s out west with little day to day variation.
Unfortunately this means that an SPS or Advisory for heat index
values near 110-112 are possible on Tuesday. Slightly cooler
temperatures could usher in the weekend but as confidence is low
regarding model guidance of a disturbance late in the week, not
willing to put too much stock into at this point. Because of this
have not strayed from NBM in the forecast. Some showers may be
possible each day with the seabreeze but that is looking more
unlikely due to the subsidence in place. At least we get to finally
dry off.

MARINE...

No significant precipitation expected tonight/Monday owing to
increasing subsidence. Moderate onshore flow expected tonight
and moderate to strong Monday, as the MSLP gradient increases.
Will defer to mid shift to determine specific zones for any Small
Craft Advisories for Monday. Moderate onshore flow Tuesday will
fluctuate between moderate and weak to moderate levels each day
through the period. Onshore flow will then drop to weak by
Saturday evening.
