.UPDATE...
High pressure anchored across the region is producing very weak
near surface winds under clear skies. This should allow for
efficient warming into the average middle 70s, with some spots
warming to near 80 F, across Southeast Texas today. Drier air
aloft will mix down this afternoon and drive mid to late day
humidities into the 30(%)s, possibly a few hours where further
inland humidities bottom out in the mid to upper 20(%)s. Clear
overnight skies and weak winds will have many interior locales
falling to around 50 F by sunrise. Another warm and mostly sunny
day in the areawide middle to upper 70s tomorrow afternoon.
Onshore flow returns that will commence the moisture pump going
into the weekend. A developing Rocky lee low/mid-upper trough on
Saturday will strengthen onshore winds and increase westerly-
northwesterly POPs to low end chances for primarily showers with
isolated thunderstorms. 31

I need some rain - like seriously - if it doesn’t rain this weekend (and chances keep dropping) - I’m gonna need to run my sprinklers.

.DISCUSSION...
Continued dry weather but with warmer temperatures are expected to-
day as onshore winds resume and mostly sunny skies prevail. A deep
ridging pattern in place over SE TX today will be evolving tonight
and Sat as the next upper low/trof deepens and moves NE across the
South/Central Plains. This more northerly track along with limited
return of moisture (PWs 1.1-1.3") and a persistent cap should keep
POPs low for much of the CWA this weekend even with the passage of
a stray disturbance aloft (Sat) or daytime heating/seabreeze (Sun).

Will keep the low POPs in place for Mon/Mon night with the passage
of the next cold front. Progs of a strengthening cap for Mon could
mean even lower rain chances should this trend continue. A cooler/
drier air mass will be moving into the area Tues behind this front.
Thereafter, a slightly more progressive pattern is expected as the
next upper trof moves in from the west. Onshore winds to return by
late Weds/Thurs out ahead of the next cold front (currently on tap
for late Fri/early Sat). Confidence for elevated POPs for this sys-
tem remain low given the indications of the strong capping persist-
ing. However, given the time of year, some or all of this could be
moot as we move forward. 41

&&

.MARINE...
High pressure has drifted into the coastal waters this morning with
light southwesterly component. Landbreeze could take shape near
sunrise then winds come back around to the south and southeast near
noon. Winds should strengthen this afternoon through Saturday as
high drifts away and pressures fall in West Texas as an upper level
s/w trough lifts out. Seas slowly building from 1 foot this morning
to 2 to 4 feet Saturday and then with persistent southeasterly flow
Sunday creeping up further. A cold front moves through SETX Monday
and into the coastal waters Monday evening. Winds picking up and
peaking Tuesday morning and will probably need an SCA at least
briefly. Isolated streamer shower may be possible Saturday but
chances look slim given the poor moisture return. Cap strengthens
Sunday and limits rain chances until near the frontal passage. Brief
window for precip with the fropa.
45

.AVIATION...
Fog on the increase over the southwestern counties and could briefly
impact LBX/SGR this morning. Otherwise VFR with high clouds and
light/variable winds becoming south and southeast. If mixing isn`t
too strong may see fog again Saturday morning at the more
problematic sites LBX/CXO.

The plant is on fire again. Weather seems much warmer, drier, and with weaker winds than vs the first fire... I wonder what effects this will have.

Missed a good chance to rain earlier, was really cloudy with grey skies. Now looks like the sun is peeking out. Need some rain to wash this green pollen off of everything. Washed my car today, but I am sure the green stuff will be back on it by morning, if not sooner.

I doubt it’s going to rain this weekend guys. We might have to wait a while before it rains. Possibly next weekend.

One thing that is confusing me is the precipitation forecast from the CPC. They keep on placing us in the above average precipitation, but the Euro is almost completely dry for our area for the next ten days. Plus the past couple times the CPC has put us in the above average precipitation area it never materialized. I’m not really putting too much stock into their forecast like I usually would.

Area Forecast Discussion
National Weather Service Houston/Galveston TX
1057 AM CDT Mon Mar 25 2019

.DISCUSSION...
Current fcst has a good handle on things. Just a few tweaks for
the update, mainly extending fog duration in the Gulf until the
front passes thru that area later tonight. 47

&&

.PREV DISCUSSION... /ISSUED 653 AM CDT Mon Mar 25 2019/
Some areas of fog linger across the forecast region, particularly
across the south and southwest counties, mostly affecting LBX and
GLS. Fog is expected to lift by 15Z today. MVFR to IFR ceilings
are expected to lift during the morning hours and should become
VFR in the afternoon. Winds will be shifting during the TAF period
due to the passage of a weak cold front. Winds will become west
to northwest in the morning and then become north in the afternoon
across the northern half of the CWA. For the southern half of the
CWA, winds will become west to northwest during the morning and
then become north tonight. SHRA expected mostly north of I-10 and
east of I-45 this afternoon as the cold front moves across the
local area. The development of isolated thunderstorms is possible
mainly across the northeastern and eastern counties. Rain activity
will dissipate after 00Z Tuesday with skies clearing through the
end of the forecast period. 24

PREV DISCUSSION... /ISSUED 459 AM CDT Mon Mar 25 2019/
Line of showers and thunderstorms along the front extending from
near Palastine to near Nacogdoches to Ruston LA. Garden variety
storms but wouldn`t rule out some brief gusty winds and small hail
though probably northeast/east of the CWA. The tail end of the
band should clip the Crockett to Livingston areas eastward this
morning.

Warm and humid across the region this morning with areas of fog
over the southwest areas intruding into Hobby/Pearland
areas...visibility of 1 mile at times with fluctuations around
that. May need a small dense fog advisory for the
Matagorda/Brazoria county region if it gets much thicker.

As the front pushes down across the region today should see some
scattered showers form beneath the cap and as cap erodes this
afternoon with temperatures climbing into the upper 70s to around
80 ahead of the frontal boundary will probably see some isolated
to widely scattered thunderstorms. Most of these should be
southeast of a Livingston to Houston to Bay City line. By early
evening the front should be near the coast and offshore more than
10-20nm by midnight. Loss of heating should bring on the demise of
the storms.

Front pushes on southward and dry air overspreads the region
tonight/Tuesday. Skies clearing and should make for nearly a
Chamber of Commerce sort of day. Wednesday expecting the winds to
turn back from the north to the east bringing back an increase in
low level moisture to the southwest areas (still dry over the
north and central and warmer) with the flow increasing Wednesday
night and Thursday. Rain chances increasing Friday over the west
in closer proximity to the upper speed max exit region. Still
looks relatively capped. Friday into Saturday rain chances
increase and Saturday looking like the beginning of the spring
season for storms in SETX. CAPE in excess of 1500j/kg and two
short waves that aren`t quite in phase...(of course this a day 6
forecast and subject to significant change)...could bring a good
chance for soaking rains to much of the area. The associated cold
front should move off the coast Saturday night or early Sunday
morning. 45

MARINE...
Some areas of patchy fog continues possible this morning,
particularly across Matagorda Bay and adjacent nearshore waters.
Light south winds will become southwest to west across the
nearshore waters throughout the day today. Over the offshore
waters, winds should become southwest to west tonight. Winds
across the Gulf waters will become north to northeast and increase
overnight after the passage of a weak cold front. SCEC conditions
are expected early Tuesday morning through Tuesday afternoon.
Seas should remain 3 feet or less across the nearshore waters and
remain 5 feet or less across the offshore waters. Easterly wind
flow will then prevail across the Gulf waters Tuesday afternoon
through Wednesday evening. Onshore flow returns Thursday through
Saturday. Another cold front could move across the coastal waters
Sunday with increasing winds and seas in the wake of the front. 24

Mesoscale Discussion 0239
NWS Storm Prediction Center Norman OK
1210 PM CDT Mon Mar 25 2019

Areas affected...Portions of southeast TX and southwestern LA

Concerning...Severe potential...Watch unlikely

Valid 251710Z - 251945Z

Probability of Watch Issuance...20 percent

SUMMARY...An isolated large hail and gusty wind threat should exist
this afternoon. Watch issuance is unlikely.

DISCUSSION...A surface cold front is located over southeast TX and
southwestern LA this afternoon based on recent surface observations
and visible satellite imagery. A thunderstorm has gradually
strengthened along the front near the TX/LA border where diurnal
heating has encouraged MLCAPE around 1000 J/kg to develop per recent
mesoanalysis estimates. Low-level flow across this region remains
generally weak, with the LCH and HGX VWPs showing westerly winds of
25 kt or less in the lowest 3 km AGL. But, mid to upper-level
westerly winds do strengthen with height, and 35-40 kt of effective
bulk shear should be enough to support some updraft organization.
Additional thunderstorms will probably develop this afternoon along
the front and move east-southeastward. Isolated large hail may occur
due to the strong uni-directional flow present above 3 km and some
modest steepening of mid-level lapse rates. Gusty downdraft winds
may occur as well where low-level lapse rates become steepened. With
the large-scale ascent expected to remain minimal across this
region, thunderstorm coverage and related severe threat will
probably remain too isolated to justify watch issuance.

A clear cool SE TX morning will be followed by a perfect Spring afternoon. The skies and lighting were beautiful yesterday evening.
