Area Forecast Discussion
National Weather Service Houston/Galveston TX
936 PM CDT Fri Jul 28 2017

Isolated showers and thunderstorms which occurred earlier this
evening near Sugar Land dissipated before sunset. The 500 mb high
pressure ridge continued to nudge southeastward this evening. The
current forecast is on track for overnight lows to be in the upper
70s over the inland areas and near 80 to the lower 80s along the
immediate coast.



.PREV DISCUSSION... /ISSUED 631 PM CDT Fri Jul 28 2017/

Sea breeze has pushed inland with a lone isolated storm just west
of KSGR. Expect this storm to remain just outside 10 mile radius
of KSGR and likely gust out. SGR may experience a brief
thunderstorm gust if anything. VFR conditions are expected tonight
with light winds. There should be enough capping during the day
to keep convection out of the TAFs. There will be a frontal
boundary pushing into the area from the NE so might see a storm or
two develop along it but coverage in CAMs looks sparse. Might see
a bit more activity in the 03-09Z Sunday time frame.


PREV DISCUSSION... /ISSUED 336 PM CDT Fri Jul 28 2017/

Another hot afternoon is in store today with many sites already
reaching heat indices of 105-108. So far it seems that the 108
values are sparse enough (only 2 so far) to not warrant a heat
advisory. The cu field isn`t looking incredibly robust right now,
but based on satellite derived PWs of 1.7-1.9 inches, I still
think we could squeeze out a few showers and storms later this
afternoon/early evening. Tomorrow will likely be a touch warmer
than today as we`ll have a west wind for most of the day. This
will allow the Brazos Valley to reach highs in the 101-102 degree
range and give Houston another good shot at hitting 100 for the
first time this summer. Although the ambient temperature will be
warmer tomorrow, the west wind will also likely allow for more
mixing to occur. This will likely keep the heat indices in the
105-109 degree range again. A heat advisory may be needed, but
that decision will be left for the midnight shift after we have a
chance to evaluate the max heat index values observed today. It is
also worth noting that due to the higher temperatures expected
tomorrow, a heat advisory may be required for the Brazos Valley
based on forecast ambient temperature and not necessarily the heat
index. Heat advisory criteria for our office is a heat index of
108 or ambient temperature of 103.

The forecast gets a little bit more interesting tomorrow afternoon
as a cold front backdoors into the area from the northeast. The
models have been speeding up the arrival of this front, and now
it`s looking like the front and associated showers/storms could
begin to reach the Piney Woods region by late tomorrow afternoon
into early evening. If the front does progress this quickly,
showers and storms will be entering the area during peak heating
of the day and have access to ample CAPE. This in combination of
the inverted V on the forecast soundings suggests that some of
these storms could become strong to severe, with gusty downburst
winds being the primary threat. The front will continue to
push southwestward throughout the night Saturday night into
Sunday, eventually clearing the area by Sunday night.

Following the front, a drier and slightly cooler period is
expected to start out the work week. However, the front is only
going help lower temperatures by a few degrees, so although we
back away from heat advisory criteria it will still be quite hot.
It looks like a more unsettled pattern will take shape for the
second half of next week as an upper-level trough over the eastern
CONUS will bring periods of showers and storms to SE Texas through
the rest of the forecast period. 11

The light southwest winds over the waters today should pick up some
tonight as a front begins to drop into Texas from the
north/northeast. By late Saturday afternoon, that front will reach
portions of Southeast Texas, but a wind shift over the waters
shouldn`t be expected until Sunday as winds head towards
northeasterly. Isolated to scattered showers and storms are possible
around the boundary, particularly farther up the coast. Winds early
next week may veer only modestly, with some variance around
