Update
Updated for evening discussion.

Discussion
The last showers have dissipated and no additional development is
expected the remainder of the night. Minor adjustments to the
temperatures curves were made where it rained but morning lows
were still on track. 22
prior discussion below:
tonight & Tuesday: this convection going on around the region
will continue to drift through the west-southwest over the next
several hours. As the shortwave trough continues to dive south,
some gradual weak subsidence will build in the wake. Due to this,
expect rain & storms to gradually wind down through early evening
& the cloud debris will gradually thin out to the southeast. Lows
will be near or slightly normal as these clouds gradually thin.

However, more clouds & some patchy fog may be able to redevelop,
especially across areas in the highway 59 corridor & especially
east of interstate 55.

The 595dm subtropical ridge axis will gradually build to the east
through the central plains on Tuesday, leading to increased thermal
warmth & some subsidence. Moisture profiles will be slightly lower
across the delta, mainly in the arklamiss delta, so this will limit
some coverage of storms somewhat across this area. Due to this,
storm coverage will be more isolated across the arklamiss delta,
while more scattered to the southeast due to pws closer to 2
inches. Similar to today, some locally heavy downpours & gusty winds
can't be ruled out but with even lighter flow, that should limit
storm intensity somewhat. In addition, thermal warmth will be
similar than today. With less coverage, we should be able to reach
into heat advisory criteria. Due to that & how limited coverage &
heat that has been across the delta today, added an "elevated" for
the arklamiss delta for Tuesday & a "limited" down to mainly the
interstate 20 corridor. Due to that, introduced a heat advisory for
Tuesday afternoon for areas that are a little more on isolated to
low-end scattered storm coverage. This may need to be expanded more
east across the highway 82 corridor towards the golden triangle but
with some higher coverage, decided to hold off introducing it for
this area for now. Dc
tomorrow night through Monday...

a fairly typical late summer weather pattern is expected to persist
across the area through the rest of the week and into the weekend.

The period starts off tomorrow night with ridging centered across
the southern plains continuing to break down as an active northern
stream persists over the northern third of the conus. The ridge is
progged to flatten with the center becoming displaced further west
into the desert southwest and less of an influence over the
arklamiss region. With that being said, one last day of heat stress
is expected on Wednesday as 850mb temperatures remain near 20 c
across the delta. This will result in high temperatures in the mid
90s, which combined with dewpoints in the low to mid 70s will result
in heat index values of 104-108 degrees. Will update the
hwo graphics to include an elevated threat area for heat across the
delta and a limited elsewhere along and north of i-20. A heat
advisory may also be needed, but will be assessed at a later time.

Heading later into the week and into the weekend, high temperatures
are forecast to remain in the low 90s with increasing coverage of
afternoon showers and thunderstorms. Several perturbations embedded
in the weak upper flow will help support this increasing activity.

While organized severe weather is not expected, an isolated severe
storm or two cannot be completely ruled out each day and the
potential will need to be assessed daily with the local microburst
checklist. In addition, pwats will remain near 2" and locally heavy
rainfall can be expected with any storms. Tw

Aviation
18z TAF discussion:
widespread showers & storms are ongoing across most of the area,
minus near gwo & glh. Any stronger storm could bring gusty winds,
heavy downpours & brief ifr drop to flight categories. Storms
will decrease in coverage after 19 23 - 20 00z. Some lower flight
categories, with low ceilings & some patchy to possibly patchy
dense fog, are possible with MVFR-ifr flight categories are
possible, at mei, hbg & pib. Expect these low flight categories
between 20 13-15z. More storms are possible by mid-morning
tomorrow across most of the region. Dc

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
