Area Forecast Discussion
National Weather Service Brownsville TX
326 AM CDT Tue Mar 29 2022

.SHORT TERM (Today through Wednesday): Mid level trough/storm
moving into the Desert SW this morning advances into the Texas
Panhandle Midnight tonight. Surface low strengthens over the
Plains tightening the pressure gradient across South Texas the
next 24 hours. 06Z special sounding indicated a modest LLJ of
37kts right where the models forecast. Latest model projections
show the LLJ intensifying 40-45 knots by 12Z, 40-50kts 30/00Z, and
GFS peaks 50-60kts along the lower TX coast by 30/09z. This is
sufficient to warrant a wind advisory for the the coastal counties
and southern Hidalgo today through much of tonight with gusts
over 40 mph. Northern Hidalgo and Brooks and possibly Jim Hogg
could see some gusts exceeding 40mph later tonight which might
warrant an advisory. The winds and still no rain raises the fire
weather concern again today but areal coverage of elevated
conditions are limited with higher dew points due to the southerly
winds. Deep mixing and with higher heights with 500mb ridge axis
passing to the east will allow for temperatures to rise a few
degrees over the last few days. Mid-Upper 80s to mid 90s are
expected for today.

Breezy to windy and sultry tonight until the storm systems front
moves into Deep South Texas a few hours after Midnight. Models
suggest a frontal passage sometime between 3-6 AM for the north and
western ranchlands and 6 to 9 AM for the RGV. Not much cooling with
this front but another round of very dry air and brisk northwest
winds. Deep Layer RH values dip well below 20 percent and
temperatures exceeding 90 degrees with a west to northwest downslope
flow 15-25 mph will translate to surface humidity plummeting below
20 percent for most of the CWA. Fire danger will be elevated to
critical for all areas and Red Flag Warning have been posted. (See
Fire weather section for more details).

.LONG TERM (Wednesday Night through Monday): The flow at H5 will
be rather zonal most of the period with a weak perturbation or two
within the mean flow. One such perturbation is expected to move
over Deep South Texas Friday and, when combined with a weak warm
front lifting north, will create the best chance for rain we have
seen in the region in a couple of weeks. However, with the whole
"drought begets drought" saying, it was tough to go higher than a
20 to 30 percent chance for showers and/or storms east of I-69C
on Friday. Still, extra clouds and an onshore flow will help keep
temperatures to near or slightly below normal for the first day of
April.

Surface high pressure is forecast to slide from the Mississippi
River Valley to the Mid-Atlantic this weekend. This will provide
an east to southeasterly surface flow this weekend into early next
week. With some added surface moisture, a few streamer showers
cannot be ruled out Sunday morning and again Monday morning.
Otherwise, rain will be difficult to come by, especially for those
in Jim Hogg, Zapata, and Starr Counties, through the forecast
period.

As far as temperatures are concerned, Thursday and Friday
mornings will be cooler than normal due to very dry air in place
with widespread middle to upper 50s to lower 60s expected. Overnight
temperatures will be back in the 60s this weekend and into early
next week following Friday afternoon's warm front. Thursday's
highs will climb into the upper 80s to lower to middle 90s across
the region before cooling a handful of degrees Friday afternoon
as the warm front lifts north. It then appears persistence is the
name of the game this weekend with highs generally ranging from
the middle to upper 80s east of I-69C to lower to middle 90s out
west.

&&

.MARINE (Now through Wednesday): Buoy 42020 reported south-southeast
winds around 14 knots gusting to around 18 knots with seas of 3.9
feet with a period of 6 seconds at 0200 CDT/0700 UTC. Winds offshore
and along the coast are slow to respond to the anticipated increase
in the pressure gradient. Low level jet of around 35 knots this
morning is just not mixing to the cooler stable water surface.  As a
mid-level trough advances farther to the east gradient intensifies
further with models showing 45-60 knots overnight Tuesday which
should allow for some of the stronger winds to reach the surface.
Initial Small Craft Advisories start over the Laguna Madre mid to
late morning with the Gulf waters seeing winds near 20 knots mid-
afternoon. Once this winds start increasing they are not likely to
relax until a cold front moves through Wednesday morning around or
shortly after sunrise. Gale force gusts although possible are not
anticipated to be frequent enough to warrant a gale watch or warning
at this time.

Wednesday Night through Sunday...Small Craft Advisories will
remain possible Wednesday night due to elevated seas. Winds will
be on the downward trend, but small craft may need to exercise
caution at times from Thursday morning through Friday afternoon
before more favorable marine conditions return this weekend. A
couple of showers and storms will be possible Friday afternoon
over Gulf waters with a few streamer showers possible Sunday
morning.

&&

.Fire Weather (Now through Wednesday): Winds will be the main issue
today with marginal relative humidity as dew points are elevated due
to the southerly flow. Some areas over the North and Western
Ranchlands may see elevated fire weather conditions a few hours in
the afternoon when RH dips below 40 percent and winds peak 15-20
mph. A Range Fire discussion will be issued for the west and north
counties today. Confidence is well above average for Red Flag
conditions Wednesday in wake of the morning cold front. With RH
levels plummeting 8-20 percent and 20 foot winds exceeding 15 mph
which warrants an upgrade of the Fire Weather Watch to a Red Flag
Warning for all areas.

Thursday... Elevated Fire weather conditions are possible again
Thursday. Very low relative humidity values between 10 to 20
percent west of I-69C and 20 to 40 percent east of I-69C are
forecast Thursday afternoon. However, the limiting factor are the
20-foot winds forecast to remain slightly below critical levels.
