.SHORT TERM...
(Today through Friday Night)
Issued at 330 AM CDT Thu Oct 6 2022
A little more low level moisture will be present today, in
particular along areas south of the I-10 corridor, as a surface low
pressure moves into the western Gulf of Mexico. Showers and
thunderstorms associated with this feature is expected to remain
mostly along the offshore waters. In addition, with subsidence
persisting across Southeast TX and mid levels being fairly dry, rain
activity inland will be limited. On Friday, moisture will continue
to push into the region, increasing PWs to 1.1-1.3 inches by the
afternoon hours, resulting in partly cloudy skies for much of the
day. This gradual rise in moisture will also result in a subtle
increase in temperatures. The highs today will be in the low 90s
inland and in the upper 80s along the coasts, and increase a degree
or two on Friday. The lows will also follow this pattern with lows
overnight in the upper 50 to upper 60s, slightly higher Friday
overnight. But the good news is that a very weak cold front moving
through Friday night into early Saturday morning, will stop this
warming trend, and bring us back to highs in the upper 80s to low
90s for the weekend. Cheers to the "Ouuu Yeahhh" feels again this
weekend

.LONG TERM...
(Saturday through Thursday)
Issued at 330 AM CDT Thu Oct 6 2022
By Saturday morning, a weak cold front will have pushed offshore
with surface high pressure building into the Central Plains and an
850mb high directly overhead. This is more of a backdoor front with
the bulk of the cold/dry air remaining well north and east of
Southeast TX and the predominant winds behind it being northeasterly
to easterly. Nevertheless it will knock temperatures down a few
degrees, so we`ll get to enjoy highs mainly in the upper 80s versus
the low 90s and lows in the upper 50s/mid 60s versus the mid to
upper 60s. It ain`t much, but it`s honest work!
An upper level cutoff low over the Baja Peninsula will keep the
synoptic pattern relatively unchanged over the weekend. On Monday,
it becomes embedded in the flow aloft leading to southwesterly flow
as ridging makes a comeback. Combine this with onshore flow
returning on Tuesday as surface high pressure pushes eastward
enough, and we have an ever so slight warming trend with western
locations reaching the low 90s again beginning Monday. On the
other hand, the moisture trend is definitely an upward one. PW
values increase to near and maybe even exceeding the 90th
percentile (~1.84") by Wednesday with an assist from deeper
tropical moisture pushing in. As a result, Wednesday and Thursday
are setting up to be the best chance of rain we`ve had in quite a
while. In fact, rain on Wednesday (October 12th) would land just
under a month since the last time we`ve had measurable rainfall
in the City of Houston (September 17th). And for those that are
curious, it`s been since September 7th for Aggieland and September
15th for Galveston. So you can expect today`s drought monitor to
become a bit more colorful...
Global models are still pointing towards a deeper upper level trough
digging down into the Northwestern CONUS mid next week that could be
the source of a stronger cold front towards the end of the week.
Uncertainty still remains with it being more than a week out, but
I choose to be hopeful! NBM temperature trends have been downward
after Thursday for the past few days. If I was doing a Lee Corso
style headgear pick for this, I`d have a cold front on my head...

.MARINE...
Issued at 330 AM CDT Thu Oct 6 2022
The period of benign conditions (light winds/low seas) continues
through Friday night. A weak cold front pushes offshore early
Saturday leading to moderate northeasterly to easterly winds and 3-4
foot seas that prevail through Sunday. At least caution flags will
be needed over the weekend as a result. Occasionally moderate
onshore flow returns early next week leading to 3-5 foot seas and
the potential for another round of caution flags.
