Area Forecast Discussion
National Weather Service Houston/Galveston TX
940 PM CDT Tue Jun 5 2018

.UPDATE...
Temperatures still plenty warm at 900 PM with temps currently in
the mid/upper 80s. Winds have been slow to decouple and the
pressure gradient is still kind of tight across the middle coast
into east Texas. The winds will eventually weaken and clouds will
begin to fill in over the W-NW parts of the region. Would not be
surprised if some patchy shallow ground fog also briefly developed
toward sunrise.

The few storms that managed to develop have since waned with the
loss of daytime heating. However, the boundary that the storms
fired on continues to languish over extreme east Texas. The 00Z
HiRes ARW continues to suggest that this boundary will become
active between around 21z and this is supported by the HiRes NMM.
The new 00z NAM is coming in dry but breaking things apart via
fcst soundings shows some potential for storms with steeep lapse
rates, little to no capping and convective temperatures in the
lower/middle 90s.

Updated some hourly T,Td and sky grids and added some patchy fog
to the weather grids. Won`t touch Wednesday until more 00z data
arrives. 43

AVIATION [00Z TAF Issuance]...
VFR conditions should remain across all TAF sites until the early
morning hours, when patchy stratus should develop similar to this
morning. Holding on to MVFR ceilings beginning around 09Z and
lasting until 15Z mainly at the inland terminals, before rising
and beginning to mix out with the help of daytime heating. Patchy
stratus should be shorter lived at the sites closer to and along
the coast. Light south/southeasterly winds will veer southwesterly
shortly after sunrise, before increasing to 7-11 kts by the
afternoon hours. Spotty showers will be possible mainly east of
I-45 tomorrow afternoon, associated with a weak disturbance that
slides south across the region around the upper-level ridge. Have
not included the mention of VCSH in the eastern TAF sites such as
UTS and CXO as best coverage still appears well east of these
sites. Will continue to monitor trends in short term model
guidance and make any necessary changes regarding precipitation
development in the 06Z TAF package.

PREV DISCUSSION /Issued 354 PM CDT Tue Jun 5 2018/...

SHORT TERM [Wednesday Through Thursday Night]...

Upper level pattern tomorrow has the short wave trough to the east
over Louisiana moving into the Northern Gulf on Wednesday. Upper
level ridging remains over Mexico into west Texas leaving
northerly flow aloft from north Texas to the NW Gulf. Forecasters
are always a little leary of NW/N flow aloft patterns as jet
streaks and vorticity maximum can sneak into the flow and initiate
convection that was not previously forecast. Forecast will keep
20/30 PoPs for Wednesday due to this pattern mainly for afternoon
convection. Synoptic and mesoscale models only produce isolated if
any convection tomorrow even with moderate instability, little
capping and 1.5-1.7 precipitable water values. SPC keeps area in a
general thunderstorm risk given the stalled outflow and frontal
boundary along with the northerly flow. Again should a storm form,
it looks like hail and damaging winds will be main threat given
instability and inverted V sounding profile in the boundary layer.

Thursday it looks like there will be more subsidence from being on
the back side of the trough and getting closer to the upper level
ridge building over west Texas.

LONG TERM [Friday Through Tuesday]...

Overall the upper level ridging expands over Texas but remains
somewhat weak. This does open the opportunity for thunderstorm
chances. Models hit Sunday harder of all of the days going forward
but there is no strong signal. Upper level support is not great
for rain chances Sunday but will basically keep 20 PoPs going
until there is a more substantial trend in the models. Even the
GFS does not show much of an increase in precipitable water values
during this time with 1.5-1.7 inches. Until there are better
model trends and support for convection, best tactic will be to
take forecasting convection as it comes in the near/short term
leaning on synoptic/mesoscale analysis.

MARINE...
The onshore flow should continue through the upcoming week. A
common pattern of slightly stronger winds during night weakening
during the morning then increasing again early evening should be
repeating most of the upcoming 5 days. A surge of deeper moisture
looks to take aim on the area late Saturday and through Sunday
night with an increase in the chance of showers and possibly a few
thunderstorms for the marine area. Not that an isolated shower is
out of the realm of possibility in the intervening days but
chances looks low. Seas should remain in the 1 to 3 feet nearshore
and 2 to 4 offshore. Will keep an eye on a forecast area of
showers and thunderstorms in the extreme northeastern region of
the Gulf. No unusual tide issues expected this week. 45

FIRE WEATHER...
Rain-free conditions should prevail across the southwest and for
that matter outside the few areas that get much in the way of
showers or thunderstorms across the east and Galveston Bay area.
The point being that with little rain the drought conditions
should gradually worsen over the coming week. Winds this coming
week though should remain fairly restrained. 45

This hazardous weather outlook is for portions of Southeast Texas.

.DAY ONE...Today and Tonight

Shower and thunderstorm development will be possible, mainly to
the north and east of a Midway to Lake Livingston line. Some of
this activity might have the potential to become strong or severe.
Gusty winds and locally heavy rainfall appear to be the main
severe weather threats.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

No hazardous weather is expected at this time.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated at this time.

$$

Locations: Northwest Houston, TX.


Thoughts: The day was hot, sunny, and dry. I don't think there were any showers, or thunderstorms, but there might have been some isolated showers and thunderstorms in and around the Houston, TX area, sometime during the day.
