Area Forecast Discussion

512 PM CST Mon Dec 7 2020

.AVIATION [00Z TAF Issuance]...

Light northerly winds overnight will gradually back to more
west/southwest later in the morning. Some potential for shallow,
patchy fog around dawn from IAH coastward, but lack of moisture
should keep impact on flight category minimal to nil.

.PREV DISCUSSION /Issued 322 PM CST Mon Dec 7 2020/...

.SHORT TERM [Tonight through Wednesday]...

In general, weather pattern remains unchanged as high pressure
system centered over west/central TX dominates the region. North
to northwest flow persists through at least, mid-week. Clear skies
and light winds will yield to good radiational cooling tonight.
Overnight lows will be in the mid 30s far inland to near 50 along
the coast. Despite a fairly shallow moisture layer, areas south of
I-10 could see some patchy fog, especially in low-lying areas.

As the surface high progresses east/southeast on Tuesday, 850 mb
temperatures begin to warm to around 10-11 C, bringing
temperatures into the upper 60s and lower 70s at the surface.
Sunny skies and slightly warmer conditions are expected on
Wednesday with highs from the upper 60s to mid 70s.


.LONG TERM [Wednesday Night Through Monday]...

As a surface high pressure continues to move further east,
onshore winds will usher in a gradual warming trend and help to
increase humidity with high temperatures reaching the mid 70s by
Thursday, overnight lows reaching upper 50s and low 60s.

Model guidance between the GFS, ECMWF and ensembles are still in
agreeance with the timing and location of a front pushing through
our area Friday night and early Saturday. Preceding this front
should be a band of precipitation pushing through on Thursday
night and into Friday evening. The best chances for thunderstorms
still remains in our northeastern counties with rainfall totals
predicted to be a few tenths of an inch to near half an inch for
our area. In the wake of this front, drier air and more seasonal
temperatures should resume.


.MARINE...

Winds and seas have decreased as surface high pressure builds
into West Texas. The surface high will be east of the region by
Wednesday morning and this will allow onshore winds to redevelop
by Wednesday afternoon. The next storm system deepening and moving
across the Southern Plains will produce a more southerly flow by
Thurs...with speeds picking up Thurs night near SCEC/SCA criteria.
This strengthening and warmer onshore flow will be overriding the
cooler shelf waters, and could be favorable for the development
of sea fog. This storm system is then expected to drag a cold
front off the coast Fri night or early Sat.
