Area Forecast Discussion
National Weather Service Houston/Galveston TX
359 PM CST Thu Jan 7 2021

.SHORT TERM [Tonight Through Friday Night]...
Wrap around clouds continue over the northeastern 1/2 of the
region and will probably sag slightly further south into the early
evening then dissipate from south to north before midnight. Cool
temperature overnight with northerly winds. Skies remain mostly
clear to clear Friday so anticipate another dry day warming up a
few more degrees in the afternoon. High pressure over N TX slides
east and weakens as the next big weather making upper trough drops
into Utah turning winds northeast Friday night. Temperatures will
likely dip to near freezing over the north beneath the mostly
clear skies.

On a different note...NWS storm survey results in Texas City
indicated an EF-1 tornado on the ground for around 0.7 of a mile
with winds approaching 110 miles per hour last night around 613 PM.
For more detail see the PNSHGX issued earlier.

.LONG TERM [Saturday Through Thursday]...

The main focus of the long term period continues to be the potential
for snow and rain/snow mix across the northern half of the area this
weekend. While it remains quite a complex and messy forecast,
there's increasing confidence that portions of SE Texas will receive
their first measurable snowfall in over two years late on Sunday
into early Monday.

The deterministic EC/GFS solutions have come into a bit better
agreement regarding the synoptic pattern leading up to the event
during the earlier part of the weekend. As a 300mb longwave
trough/upper low approaches the Four Corners region overnight on
Saturday/early on Sunday, a surface cold front will advance towards
the northern counties. Meanwhile, a developing coastal
trough/surface low in the southwestern Gulf will push towards the
offshore waters, with associated moisture advection pushing total
PWs to around 1.0 in by Sunday afternoon. Furthermore, the region
will lie within the favorable left front quadrant of an upper jet
streak associated with the aforementioned upper low, providing ample
upper-level divergence for efficient/widespread precipitation.

Precipitation on Sunday will initiate as rain across the entirety of
the area. However, model soundings and 850mb temperatures to the
north of the Columbus-Conroe-Livingston line continue to show
favorable profiles for mixed phase precipitation to snow as
temperatures drop during the evening and overnight hours. NAM
continues to be fairly aggressive in depicting frontogenetically
enhanced snowfall across the northern third of the area during this
time frame, but given warmer temps with limited winter precip in GFS
solution and less aggressive EC solution, have opted to forecast a
"middle ground" for the time being. In general, snowfall amounts (if
accumulation does take place) will be largely driven by mesoscale
forcing and thus are not focusing on specific totals for now.
However, confidence is building that we'll see some form of
measurable snow during this event as model solutions continue to
converge. The rainfall threat from this event across the Houston
metro and areas south must also not be disregarded. The
aforementioned synoptic pattern will also prove favorable for the
development of locally heavy rainfall as the surface front/coastal
low traverse the area on Sunday and Monday.

A colder and quieter period is expected in the wake of the frontal
passage on Monday as the coastal low advances into the central Gulf.
Daytime highs in the upper 50s/lower 60s and overnight lows
generally in the 30s expected through mid-week as surface high
pressure develops over the area. A warming trend is expected by mid-
week as a more southwesterly flow pattern develops. No precipitation
is anticipated between Tuesday and Thursday at this time.

.MARINE...
SCEC flags hoisted for the 20-60nm waters tonight through midnight as
winds of 15 to 20 knots gradually diminish after midnight.
Offshore flow will continue through Saturday morning then become
more easterly Saturday night strengthening and will looking for
SCA conditions with winds of 20-30 knots and seas building to 5-8
feet nearshore and 7-10 feet Sunday and Sunday night as the
coastal low tracks up the coast. Still some question as to the
exact track so this forecast is more in the middle of the pack for
the winds...if the system tracks more offshore then winds will
likely be stronger and weaker if it tracks as far north as
Galveston. Stay tuned. The impacts from this will be beach and low
lying coastal flooding, strong rip currents and may warrant a
coastal flood warning for more significant impacts with the
persistence of these stronger winds. The cold front should shove
off the coast early Monday and the strong winds should start
tapering off Monday afternoon.
