.DISCUSSION...
A cold front has pushed through the area, and a mix of light rain
showers and drizzle are being seen across much of Southeast Texas.
That should slowly wind down through the night as drier air flows
in. That drier air will also be much colder, prompting a freeze
warning for several counties in the northwest overnight. Inland
areas that don`t see a freeze tonight will almost certainly see
one tomorrow night, and so a freeze watch is in effect for the
rest of inland Southeast Texas. Wednesday night may only be
slightly warmer than Tuesday night, but the second half of the
week will feature a slow, but gradual warmup with fair weather.
Temperatures will only start to approach seasonal averages this
weekend.
.NEAR TERM [Through Tonight]...
With front through the area, winds have become northwesterly
across Southeast Texas, and have increased with sustained winds
into the mid teens and gusts into the 20s and as high as 30 mph
at the coast. The wind advisory at the coast looks to verify
nicely. An argument could be made to expand the advisory inland a
bit more, but is marginal enough that we will hold off on that as
winds are more or less near the forecast max.
Water vapor imagery continues to show a string of very weak upper
disturbances moving across the area as shown in short range model
guidance. This is supporting the light precipitation, but upper
jet placement is fairly poor at the moment. While we are likely to
see the jet drift into a better position late tonight, the influx
of drier air will keep a good setup out of phase.
Temperatures have finally begun to slide as the layer of
northwesterly winds and cold advection becomes deeper. From here
on out, we`re just getting colder. Have not meaningfully changed
the low temperature forecast, so the current freeze warnings have
been left in place, untouched. Did give a brief
thought to expanding south a bit, particularly with the northern
edge of Grimes County, but don`t think that any potential value in
expanding the warning would outweigh the confusion of expanding
it, particularly since most of Grimes is still expected to stay
above the freezing mark.
There is still a non-zero chance that the incoming cold air will
overlap with lingering moisture to provide a brief spurt of a few
sleet pellets. I guess...technically...a flurry isn`t even out of
the question, either. But, the phrase really doing the work here
is `non-zero`. Or, in other words,
. This scenario is unlikely,
but given the buzz flying about today, I wanted to investigate
what would be required to actually see it happen.
If...IF (Big If)...anything pings out of the sky, look/listen for
it to happen in the late overnight hours - 3-6 am...ish - when
the closest thing to an area of frontogenesis aloft will match up
in the northwest (Caldwell, College Station, Madisonville,
Crockett, etc) with some PWATs just under half an inch and
falling. Again...IF...winds are expected to dry off the roads,
plus warm ground will mean no real impacts. Mainly just something
to speculate about around the water cooler today.
