Looks like 1 more day of this glorious low dew point weather and then sweaty sauna hell season kicks off. At least it's been cut down to 5 and a half months instead of the normal 6.

Not concerned. Euro and EPS look great. CPC has a bullseye over southeast Texas as well.

They can actually use the rain more.

The 0z Euro and EPS look outstanding if you want rain here in southeast TX. They match up perfectly to what the CPC is showing.

...New AVIATION...

.SHORT TERM...
(Today through Thursday Night)
Issued at 235 AM CDT Wed May 3 2023

Increasing southeasterly flow at the surface and ridging aloft
will lead to warmer conditions across SE Texas today and Thursday
with highs climbing into the mid to upper 80s. Overnight low
temperatures will dip into the low 60s north of Harris County,
mid 60s along the I-10 corridor, and to near 70 along the coast.
Overnight low become unseasonably warm Thursday night due to the
southeasterly flow and overcast skies causing low temperatures to
only dip into the low to mid 70s for most of the region.

Can expected some patchy fog forming in low lying areas this
morning when winds become calm. This fog won`t last long and will
dissipate shortly after sunrise - though may make a return tonight
into Thursday morning. There may be very isolated streamer
showers this afternoon, but the chance of precipitation increases
Thursday. The upper level ridge begins to weaken as a few
shortwaves traverse across Texas. These disturbances will bring a
chance of showers and thunderstorms will tap into the 1.5" to
near 2" PWATS Thursday afternoon into Thursday night. While the
majority of the storms that develop Thursday will be general
thunderstorms, there is a Marginal Risk of strong to severe
thunderstorms for the northwestern parts of the region.

.LONG TERM...
(Friday through Tuesday)
Issued at 235 AM CDT Wed May 3 2023

Synoptic pattern looks relatively unchanged for Friday as ridging
continues across the Plains/Mississippi River Valley. Shortwave
energy is expected to round the bottom of this upper level ridge,
tapping into 1.7-1.9" PWs to bring isolated showers and
thunderstorms during the day. NAEFS mean 850mb temperatures are
progged to exceed the 90th percentile with deterministic models
showing 850mb temperatures reaching 17-19C during the afternoon.
This comes with southwesterly flow in the lower levels and a 590 dam
midlevel ridge over the Gulf of Mexico. These factors point towards
unseasonably warm temperatures in spite of the cloudy skies with
highs progged in the upper 80s to lower 90s. Dewpoints are expected
to reach the mid to lower 70s during this time frame, which should
bring peak heat indicies near triple digits. While these conditions
do not meet the standard criteria for a head advisory, early season
heat events can be especially stressful on the body. Those planning
to spend time outdoors should practice heat safety on Friday through
portions of the weekend. Be sure to drink plenty of water and limit
outdoor activity when possible. Overnight lows will also be
unpleasantly warm, generally in the mid to lower 70s across SE Texas.

The aforementioned upper level ridge should amplify and drift
eastward through the Mississippi River Valley on Saturday. 850mb
temperatures are progged to rise by a degree or so, which should
bring a slight increase to highs and more widespread triple digit
heat indicies. Periods of showers/storms remain possible through the
weekend and into next week as more shortwave energy rounds the
bottom of the upper level ridge. The continued eastward progression
of the upper level ridge should reduce its influence over the
region, providing a mild reprieve from the unseasonable heat on
Sunday through Tuesday.
