Dec. 3 20

 Summary: White alto stratus clouds looked to cover most of the sky with maybe some occasional clearing, during the morning, afternoon, and maybe evening and night. The sky may have looked clear during the evening and night. (Sorry I was not paying that much attention.) The wind speeds were calm with moderate and moderately strong gusts. I believe there was a 0 percent chance for rain for the Houston, TX area. I did not hear about or see any rain drops falling anywhere in, or near the Houston, TX area. I did not see, or hear any rain drops where I was in the Houston, TX area, during anytime of the day. It felt very cold, during the early morning and late night. It felt cold, during the mid-morning and night. It felt very cool, almost cold, during the late morning and evening. It felt very cool, during the afternoon.

will begin eroding from the south over the next few hours.
Following this, VFR conditions will prevail across the area.
Northwesterly flow will prevail through the afternoon with wind
gusts up to 20 knots at GLS through the morning hours. Winds will
gradually become light and variable across the area around sunset

SHORT TERM [Friday Through Saturday Night]...

In the wake of yesterdays cold front, not much in the forecast for
active weather. Cloud coverage will still persist through the
evening and night for the eastern half of the CWA. With the boundary
still along the TX/LA border, the low in OK, we still are in the
area that the cloud coverage will stick around for a bit. High
pressure is building in from the west will clear out most of the
clouds through the night and relax the gradient which will calm
these chilly winds down. Coastal counties will stay a bit more
breezy than the rest of the CWA but speeds will decrease there too
tomorrow. The partly cloudy skies will help keep low temperatures
somewhat more mild than what they could be. Northern counties will
get close to freezing tonight and tomorrow night and coastal
counties will get to the 40s. Highs today peaked in the mid 50s and
tomorrow is looking about the same with mid to upper 50s across the
CWA. Biggest downfall will be the nightly higher humidities making
it a bit harder to start the backyard campfires. 35

LONG TERM [Sunday Through Thursday]...

Heading into the weekend, the progression of an upper low over
western TX will place SE TX within the left front quadrant of an
associated jet streak, a pattern indicative of favorable upper-
level support for the development of showers and storms on
Saturday and Sunday. That being said, any development which does
occur should be limited in both coverage and intensity as total
PWs should remain below 1.0 in while model soundings indicate
relatively low instability. The bulk of any showers that occur
should remain confined to the coastal waters, where low-level
moisture availability will be best. Have also included some
slight chance PoPs (15-20%) inland, mainly across the SW zones,
given the favorable synoptic pattern. One more certain impact of
this pattern will be an increase in cloud cover, which should keep
daytime highs down over the weekend. Highs are unlikely to
eclipse 60 degrees on Saturday afternoon, while a modest increase
into the lower 60s on Sunday as skies begin to clear. Overnight
lows should remain in the upper 30s across the northern zones, in
the low 40s across the Houston metro, and close to 50 near the
coast.

As we head into next week, the period of relatively benign
weather continues as surface high pressure once again takes hold
over the south central CONUS. With this feature reestablishing
itself by Monday, expect a return to northerly winds and a
continuation of below normal high and low temperatures. With
total PWs sinking below 0.5 in and no forcing to speak of,
conditions should remain dry through Wednesday. Models still are
in disagreement regarding the redevelopment of onshore winds and
the potential approach of a cold front by mid-late next week. For
now, our next chance at widespread precipitation looks to fall
within the Thursday-Friday timeframe.

MARINE...

Offshore flow will be increasing slightly overnight as cold air
settles in across the region. SCA conditions should prevail over the
Gulf and may see winds in the lower portions of the bays increase to
SCEC but not that confident yet. Friday morning after sunrise winds
should start decreasing and 7-13 knot winds should prevail through
the weekend. Stratiform rain chances increasing Friday night into
Saturday overspreads the waters then tapers off Saturday night as
the upper low departs.
