Area Forecast Discussion
National Weather Service Houston/Galveston TX
220 PM CST Sat Jan 9 2021
.SHORT TERM [Tonight through Sunday Night]...
Winter storm system is still on schedule to move eastward across the
state tomorrow through late tomorrow night. Current south Texas cloud
cover will be moving into our southwest and western counties later this
afternoon and the rest of the area tonight, and look for areas of rain/showers
to develop late tonight but more likely tomorrow morning. These rain
areas along with the chance of some thunderstorms mainly near/along
the coast will be on the increase as the day progresses as the surface
low develops/strengthens along the lower to middle coast and intensifies
as it moves generally eastward across our coastal waters in the afternoon
through evening hours. As winds shift to the northeast and north across
our area, temperatures will be falling, and model soundings are still
forecasting a transition from rain to show across our northern counties
beginning as early as the mid to late afternoon hours tomorrow. After
coordinating with adjacent offices, have upgraded our Winter Storm Watch to
a Winter Storm Warning where 1 to 4 inches of snow with locally higher amounts
can be expected. Because, the far northern edges of both Polk and San
Jacinto counties have some potential to get similar snowfall amounts, have
gone ahead and placed them under a Winter Storm Watch. These two counties
might need to be upgraded to a warning later tonight or early tomorrow
morning if model trends continue. Speaking of model trends, we are still
seeing a large range of potentially higher snowfall amounts (>4 inches)
across our far northernmost counties, and our expected amounts might need to
be raised in future updates if we begin to see any model convergence toward
these higher totals. As noted over the past several days, there will likely
be a sharp gradient of snow accumulations, and any slight storm track
deviations and/or mesoscale forcing could become a significant player as to
where the 1 to 4 inch or higher totals end up.
Further to the south where temperatures will stay too warm for any winter
precipitation (it will end up being a cold, cold rain), rainfall totals
for this event are anticipated to average around one inch with higher
totals mainly near the coast and offshore locations that will be closer
to the surface low (especially near the Matagorda Bay area). Also expect
breezy/windy conditions to develop as this system moves on through,
especially for locations closer to the coast and especially offshore. 42

.LONG TERM [Monday Through Saturday Night]...
In the wake of this frontal system, a high pressure should build
over the region. CAA and clearing skies will allow temps Monday
night and into Tuesday morning to steadily drop into at or near
freezing levels. North of I-10 and outside of the Houston metro
area, temps will be below freezing for several hours overnight.
South of I-10, temps will be at or near freezing overnight. Along
the coast, more cloud coverage and moderation from The Gulf will
help keep overnight temperatures in the mid to upper 30s. For
Tuesday night, overnight temperatures will only be a few degrees
warmer compared to Monday night, but areas north of the beltway will
still be at or near freezing overnight.
After that, high pressure should settle in over our region for
several days and temps will gradually warm back to the 60s by
Wednesday. Global models indicate a low pressure system sitting over
the Baja Peninsula for several days with zonal flow sending short-
wave ripples across SE TX. The only impacts expected from this would
be increased cloud coverage. The Euro shows this Baja low merging
with a developing front on Friday and pushing east, but any precip
would develop well east and offshore of our CWA. The GFS is more
aggressive with this front developing on Friday, however it does not
interact with the Baja low and precip still remains east and well
offshore of our CWA. KBL

.MARINE...
Northeasterly winds will transition to more easterly winds today. As
a coastal low begins to develop late tonight and early Sunday
morning, winds will begin to increase in our SE offshore waters with
possible SCEC conditions tonight transitioning to SCA early tomorrow
morning. In the wake of this coastal low, winds will become
southeast and increase to near 25 knots. As the cold front pushes
off Sunday evening and early Monday morning, winds will continue to
increase with gale force conditions possible beginning as early as
Sunday night with seas forecast to range from 7-11 feet. With strong
offshore winds, low water advisories are possible during this time
frame. SCA conditions are expected to persist through Monday and
offshore winds will continue through the middle of next week before
transitioning to west/southwesterly winds by late Wednesday night
and persisting through the rest of the week. KBL

.PREV DISCUSSION... /ISSUED 1150 AM CST Sat Jan 9 2021/
AVIATION...
Still expecting VFR conditions to persist for the rest of the day and
on through the overnight hours with gradually increasing mid to upper
level clouds. Generally expect mostly light E to NE winds. Steadily
decreasing ceilings can be expected tomorrow as the coastal low approaches
the area with MVFR levels likely and IFR levels quite possible, especially
heading on into the afternoon hours when -RA/-SHRA will be on the increase.
There will be the possibility of some TSRA to develop too, mainly to
the S of IAH where the better instability is anticipated. Also look
for increasing/gusty E to NE winds to develop as the day progresses.
We will need to start talking about adding afternoon snow to the
CLL and UTS TAFs with the 00Z package. 42
