Area Forecast Discussion
National Weather Service Houston/Galveston TX
404 PM CDT Thu Jun 3 2021

.SHORT TERM [Through Friday Night]...

Today is looking almost identical to yesterday with showers and
thunderstorms developing along the sea breeze. A shortwave ejecting
off of a deepening upper level low in West Texas will move across
our area into the evening enhancing the diurnally driven convection.
PWATs are over 2 inches this afternoon, so locally heavy rainfall
will be possible causing ponding along low lying areas. Based short
term PoPs towards the HRRR as it has been initializing fairly well
all day. Precipitation will become largely widespread by the late
afternoon into the evening for most of the area but the immediate
coastline. May want to plan for longer commute times for the evening
rush tonight. There will be a lull in the precipitation late this
evening into tonight, but this won't last long as scattered showers
and thunderstorms fills back in from west to east by day break as
yet another shortwave passes through the area. The upper level
trough becomes a closed low early Friday and begin its slow approach
to Southeast Texas through the day on Friday. There again remains a
chance of locally heavy rain through Friday evening. Grounds are
fairly well saturated from weeks of rainfall, so will need to watch
closely for any flooding concerns. The WPC has placed the western
half of the CWA in a Slight Risk of the area for Excessive Rainfall.
Total rainfall through Friday night will be around 1 to 3 inches
with locally higher amounts possible.

Temperatures through the short term will not vary much thanks to
overcast skies. Low temperatures tonight will dip down to near 70,
then temperatures rise to near 80 in the afternoon tomorrow, then
back down to near 70 Friday night.

.LONG TERM [Saturday through Thursday]...

Environmental conditions will remain favorable for an active
weather pattern this weekend through the upcoming week. Confidence
in the potential for flooding across portions of SE Texas during
the extended period has increased as models get a bit more in sync
with a synoptic pattern that reflects favorable conditions for
periods of heavy rainfall.

An upper level low over Western and Central TX is progged to move
slowly eastward Saturday, continuing favorable jet dynamics for
storm development across Southeast TX. In addition, a few smaller
disturbances are expected to round the base of the associated trough
and move over the local area from time to time, further enhancing
the potential for storm activity. With persistent southerly flow
continuing to provide good surface moisture transport over the
local area (PWs of 1.8 to 2.0 inches), periods of locally heavy
rainfall are likely on Saturday. The upper low is expected to
reach Eastern/Northeastern TX by Sunday and meanders over this
area through Monday. Although the global models weaken the
low/trough over the Southern Plains, pulses of abundant surface
moisture will continue to move through the area, enough to
maintain periods of showers and thunderstorms both Sunday and
Monday. Beyond that timeframe, southerly flow will remain over the
local area, maintaining PWs of 1.7 to 2.0 inches through the end
of the forecast period. Unfortunately, models are now keeping the
upper level ridge more to the west midweek, thus, extending the
potential for active weather through the end of the forecast
period.

Total rainfall amounts of 4 to 7 inches can be expected during
the next 7 days, locally higher amounts are possible with very
slow moving storms or training. Considering the spectrum of
expected rainfall amounts, along with the fact that we will have
saturated soils lurking across portions of the CWA and water
levels running high in a few of our rivers, Southeast TX could
experience some flooding issues during the next few days. Flash
Flood Watches may begin to be issued in the next day or so.
Please stay alert and prepared in case one is issued for your
area.

High temperatures this weekend will be in the low to mid 80s and
in the mid to upper 80s next week. Low temperatures will
generally be in the upper 60s to low 70s inland through early next
week, and in the low to mid 70s through the end of the period.

-- Given it's the long term period, changes to the forecast could
   occur, although at this time, most models are in fairly good
   agreement with the long term synoptic pattern.

.MARINE...

Light winds will continue through the end of the work week across
the bays and waters along with seas of 1-3 feet. Winds increase
this upcoming weekend, possibly requiring Caution flags with seas
building up to 6 feet as a long fetch from the southern Gulf
develops. Chance of showers and thunderstorms can be expected
each day, with the heaviest activity expected to occur Friday
through Monday. Tides levels may also increase Sunday into early
next week.

For those planning to visit the beaches this weekend, strong rip
currents could occur across the Gulf facing beaches. Make sure to
monitor the local beach advisories.
