area forecast discussion
national weather service houston galveston tx
356 pm cdt Fri oct 18 2019

Short term tonight through tomorrow)
Weak upper level ridging is over SE tx and this feature will get
nudged eastward tonight as a weak short wave trough over the
western high plains pushes east. A weak onshore flow coupled with
moistening of the boundary layer, clear skies and limited mixing
should set the stage for areas of fog to develop. SREF ensembles
hinting at pretty good coverage W NW of houston tonight and have
added patchy fog to the weather grids after 09z.

Have issued a coastal flood statement for the potential for some
minor coastal flooding on gulf facing beaches at high tide. Water
levels could reach 3.5-3.8 feet at high tide around 10 pm and there
could be some wave run up to the dunes on area beaches and some water on
vulnerable roads like beach dr. In surfside.

The trough will induce a weak area of low pressure to develop over
the red river valley. Weak onshore winds will develop over the
region as the low moves east. The low will drag a weak boundary
toward SE tx that will likely stall just north of the CWA Saturday
afternoon. Modest directional and speed convergence coupled with pw
values increasing to around 1.70 inches suggest that some light
precipitation will develop. Have added 20 pops for a small area around
galveston bay for Saturday afernoon.The GFS is the most aggressive with
rain chances on Saturday but it gets strong support from the nmm and
additional support from the 12z ECMWF and the href. 43

Long term (Sunday through Friday)
A somewhat negatively-tilted upper plains 5h trough will travel
into the great lakes region through Monday. At the surface, a
weak surface boundary will work its way into the CWA and wash out
somewhere near the coast early Sunday. A modest chance for early
(Sunday) morning frictional land-sea interface streamer showers
to develop along and south of i-10, or just downstream of this
weakening boundary. Onshore flow returns through the day Sunday
and this moisture return will keep a slight to low end chance for
primarily showers with isolated thunder in the forecast through
the day into evening hours. Higher moisture Sunday morning will
make for a mild sunrise in the upper 60s to lower 70s... Warming
the afternoon well up into the middle to upper 80s.

A cold front will come across the region late Monday morning into
the afternoon and increase Monday's rain chances to likely. A
decent westerly push of a near 1016 mb high out of the rockies
should have the front entering our northern counties by 10 or 11
am and then have it off the coast by the late afternoon. Widespread
swath of rain accompanying the front as it travels on through
with QPF in the half an inch to 2 inch range still looking like
the most likely scenario for the majority of southeastern texas.

The area will get clipped by the tail end of a northeastern-lifting
jet so, with the best frontogenesis occurring during daytime
warmth, there is a higher prob of more areawide thunder.

High pressure expands in from late Monday through Tuesday with its
eastern exit on Wednesday swinging northerlies back onshore by
Wednesday afternoon. Nil rain chances will exist through late week
with subsequent mornings warming up from the chilly 50s (Tuesday
am) to back into the 60s by Thursday morning. Cold air advection
behind Monday's frontal passage will make Tuesday the coolest day
of the week... Afternoons warming from Tuesday's 70s into the 80s
by mid Thursday afternoon. Southerlies and moisture increase
ahead of the next cold front that currently slated for a Friday
arrival. 31
