Update
Updated for morning discussion.

Discussion
Current scans of radar depict some isolated light shower activity
across the arklamiss. However, capping will prevent any
significant development of showers and storms this evening. High
temperatures were lowered a few degrees due to cloud cover across
the region. However, heat index values could still surge into the
upper 90s as dewpoints continue to increase as moist gulf air
continues to advect into the region from the south. Jpm3
prior discussion below:
today and tonight: a warm day is on tap to kick off the holiday
weekend. After morning stratus lift and break up, strong warm most
ssw low level flow, increasing insolation, and rather high low mid
level heights will support high temps near 90. The juxtaposition of
hot conditions and high dewpoints in the low mid 70s will result in
heat indices nearing the triple digits across much of the area.

We'll continue to highlight the areas with the greatest potential
for 100-105f apparent temps in the hwo. While this wouldn't be as
big a deal later on in the summer, it is a holiday weekend and
somewhat early in the season for this degree of heat stress, so
we'll continue to devote added attention to this item.

Rain chances will be rather limited through the day thanks to a
strong cap. Somewhat better rain chances are expected over the
northern portion of the area late tonight as a convective complex
over mo ar spreads southeastward toward the area. These storms
will likely be on a weakening trend when if they reach our CWA due
to decreasing instability and increasing inhibition. However with
any storms that make it into the highway 82 corridor, there is
some potential they will still be strong enough to produce
damaging winds and perhaps marginally severe hail. We'll continue
to highlight the severe threat in the hwo and split out separate
graphics to differentiate between the late tonight early sun
morning threat and storm potential over the remainder of the
holiday weekend. Dl
Sunday through Friday... It is possible that a decaying MCS might be
dropping over our northern most zones come sunrise Sunday but
otherwise main rain chances will hold off until the evening. Sunday
morning wl still have a 591dam high centered over the central gulf
with at least a 1016mb ridge nosing west across southeast
mississippi from the eastern gulf as well. This high pressure
surface and aloft will try to hang tough over our CWA while a
shortwave trough associated with a closed low centered over
manitoba ontario of canada, swings east supporting a cold front that
will be dropping toward our cwa. Our surface dew points will be in
the lower 70s Sunday morning but the pwats will be less than an inch
and a quarter over our CWA except our western most zones. As the
day progresses moisture will continue to pool ahead of the
approaching cold front and the cap associated with the high pressure
over the region will weaken. Early Sunday evening the cold front
will approach our northwest zones in an environment where heights
will remain rather high but our pwats will be in excess of an inch
and three quarters. Mlcapes are progged in excess of 2500j kg with 0-
6km shear around 40kts and mid level lapse rates around 7.0c km to
support isolated strong to severe storms over the northwest half of
our CWA Sunday evening into Monday morning. Monday the closed low
will still be just north of the great lakes region while ridging
surface and aloft remains centered to our southeast. The cold front
is expected to stall across the central portions of our cwa.

Although weaker environmental parameters are expected, daytime
heating will lead to another round of strong to severe storms across
our CWA Monday, especially over east central mississippi. The main
threat with storms Sunday and Monday will be damaging straight line
winds but hail greater than quarters and locally heavy rainfall will
also be possible especially Sunday evening. The large closed low
will lift north back into canada very slowly Tuesday and Wednesday
and it will take until Thursday night before our CWA will be free of
its influence. Although the stalled frontal boundary will have
weakened by Tuesday, it will remain the focus for diurnal
thunderstorms each day through Thursday. The GFS is much farther
northwest, but the canadian and ECMWF have a shortwave trough over
the southern plains Friday that will help increase rain chances over
our CWA going into the weekend. 22

Aviation
12z TAF discussion:
MVFR ifr stratus will continue through the early morning hours,
lifting dissipating by mid late morning.VFR conditions will
prevail through the remainder of the day and into the early part
of tonight. S SW winds may gust to 20-25 kt at times during the
daytime hours. Late tonight, stratus will return with ceilings
again falling to MVFR ifr levels. A weakening line of tsra with
gusty winds may reach the glh gwo gtr area after 08z Sunday
morning. Dl

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.
