Area Forecast Discussion
National Weather Service Houston/Galveston TX
1150 PM CDT Sun Jun 6 2021

.AVIATION [06Z TAF Issuance]...

CIGS are starting to lower in spots across SE TX at this time, but
given the slightly increased southerly flow just above the surface
(20-25kts), will expect CIGS to bounce in and out of MVFR through-
out the overnight hours. Near-term models are still holding off on
the return of precipitation into our northern CWA by mid/late mor-
ning...then spreading south into the rest of the region during the
afternoon. Not very confident that this activity will make it near
the coast so have kept the mention of VCTS for sites mainly along/
north of the I-10 corridor (ie SGR northward). Latest runs seem to
be keeping with this trend with the shortwave tracking across N/NE
TX. Will expect things to quiet down once again by the evening. 41

.PREV DISCUSSION...  /ISSUED 257 PM CDT Sun Jun 6 2021/

SHORT TERM [Through Monday Night]...
The showers and thunderstorms that developed this morning have moved
east of the region leaving us with partly cloudy skies and light
southerly winds. Cannot out rule that some additional isolated to
scattered precipitation develops late this afternoon along the
seabreeze, but coverage should be fairly limited. The atmosphere
remains well saturated, so locally heavy rain may happen where a
thunderstorm pops up. The increased sunshine combined with dewpoints
in the mid 70s has led to a fairly hot day across the area with heat
index values climbing into the mid 90s with some areas even getting
into the triple digits.

Synoptically speaking for today, the upper level low that has been
over Texas the past several days will be lifting to the northeast
overnight tonight into Monday. However, shortwave troughs will still
be rounding the underside of low that will pass through our region.
The first passed through earlier today which triggered this
morning's precipitation, and the next one will be arriving Monday
morning. This will bring additional showers and thunderstorms to areas
mainly north of I-10 through noon. If this shortwave is faster, then
expect mainly showers with some isolated thunderstorms through the
mid morning. However, if this shortwave is a little bit slower
allowing for more daytime heating to destabilize the atmosphere then
expect more thunderstorms with some of them becoming strong. The
area that would have the best potential for some stronger
thunderstorms will be the extreme northern counties (Houston,
Trinity, Polk). The SPC has placed this area in a Marginal Risk for
tomorrow. Another shortwave will move through in the late evening
into the overnight continuing the chance of showers and
thunderstorms for the northern half of the CWA. Like today, the
atmosphere will remain well saturated so any thunderstorms that do
form may be able to produce a quick inch or two of rain. Normally
this wouldn't be too much of an issue, but the ground remains very
saturated from the past several weeks of rain. The WPC has placed
areas north of I-10 in a Marginal Risk of Excessive Rainfall with
portions of Madison, Houston, and Trinity counties in a Slight Risk.

Monday is looking to be another muggy day across Southeast Texas.
High temperatures will again climb into the upper 80s to low 90s
with heat index values approaching triple digits across the area.
Overnight lows tonight and tomorrow night will be mild with
temperatures bottoming out only in the mid to upper 70s.
