.SHORT TERM...
(This evening through Sunday night)
Issued at 215 PM CDT Sat Jul 20 2024
Due to some drier air filtering in from the north, the area is
seeing only some isolated showers and storms with it clustered
east of I-55 and along/south of the I-10/I-12 corridor. However,
for this area, we have already had repeated rounds of rain the
past couple of days and the current line looks to be training a
bit, so where is some concern of isolated flash flooding.
Otherwise, there really has not been much change in the pattern so
it continues to be day to day diurnally driven hit and miss showers
and storms.
Temperatures will remain in the upper 80s to low 90s if showers
and thunderstorms don't impact an area. However if it does it may
be into the 70s and low 80s instead, but due to the isolated
nature of the rain today left it overall unchanged.

Not sure what to say other than it's more of the same. We continue
to have the same summer pattern showers and storms through most of
the next week. Since the showers and storms continue for the
mostly foreseeable future, still keeping an eye on flash flooding
potential. PoP chances go down slightly and max temps go up as we
approach mid to late next week as the upper level ridge mostly
dominating over the western CONUS will drift eastward. We'll still
have daily chances of storms but not as much as we've seen a few
days ago. But without the more widespread rain chances, high
temperatures will likely start creeping towards heat advisory
criteria again especially late next week.

Terminals will either be in VFR if not impacted by any showers and
storms down to MVFR or lower if there are storms. The coverage of
showers and storms is a little less than the previous days so
tried to be more laser focused on the best times for convection at
specific terminals but otherwise the better chances will be east
of I-55 as well as along/south of the I-10/I-12 corridor. -BL

Issued at 215 PM CDT Sat Jul 20 2024
Light onshore flow continues for the coastal waters for the whole
forecast period. Only concerns will be higher winds and waves in
and near thunderstorms and the possibility of waterspouts,
especially in the morning hours.
