Hot Temperatures, Excessive Rainfall, and Severe Thunderstorms in the Eastern U.S.
Hot temperatures are expected again today along the Mid-Atlantic, Southeast, and lower Mississippi Valley. Heavy to excessive rainfall from thunderstorms today in parts of the Midwest to the Mid-Atlantic regions may bring areas of flooding. Severe thunderstorms pose a risk for damaging wind gusts across the Mid Atlantic region again today.

Issued at 1245 AM CDT Sun Jul 5 2026
- Although the heat and humidity of early July will persist, our
daily rain chances look to continue through at least Tuesday
with a low-end severe risk over much of the region today.
- An induced trough axis will hold serve for a few more days as we
remain flanked by a ridge to our east and west, keeping the more
intense summer heat at bay at least temporarily.
- Forecast confidence continues to increase that upper ridging
will begin to exert greater influence across our region late
next week, which would mean a trend toward hotter and drier
conditions once again.

.DISCUSSION...
Issued at 1245 AM CDT Sun Jul 5 2026
Mother Nature delivered some impressive fireworks of her own over
the Independence Day holiday, and the longwave pattern will favor
a continuation of scattered showers and thunderstorms once again
today and into the first half of next week. In fact, the next wave
of convection is ongoing toward the I-30 corridor where a decaying
MCS continues to slowly advance SE of the Red River. Although wind
speeds have dropped off considerably from early this evening when
it was still upstream over parts of central and eastern Oklahoma,
frequent to near continuous lightning is still accompanying these
storms. However, do expect the weakening trend to continue as the
convection moves south of I-30 through the pre-dawn hours before
largely diminishing toward daybreak.
In its wake, look for residual outflow boundaries to set up and
serve as a focus for renewed convection later on today as strong
sfc heating helps to further destabilize the atmosphere and high
temperatures surge back into the lower and mid 90s once again. For
this reason, SPC has highlighted the vast majority of our region
in a Marginal Risk for severe weather later today. The threat of
damaging wind gusts will be primary with this low-end risk in any
storms that develop through this evening and potentially overnight
if another MCS is able to manifest farther upstream. In addition,
can`t rule out some small hail as well but it should be much more
isolated and confined to the most intense storms.
Heading into next week, our region will effectively remain in an
area of induced troughing between a ridge axis just off the SE
coast over the Atlantic and a stronger one building to the west.
Given this pattern, we should expect more scattered convection and
largely diurnally driven through Tuesday before the ridge out west
begins to expand closer to our region by mid to late week. In this
scenario, our rain chances will be greatly diminished while summer
heat really ramps up with potentially our hottest temperatures so
far this summer.

(12Z TAFS)
Issued at 614 AM CDT Sun Jul 5 2026
Outflow boundary from previous convection has now moved south of
the I-20 Corridor and was located from near LFK to near HEX and
continues to make quick progress south and east. A broken line of
convection was observed along and in the wake of this boundary
with greater coverage across East Central and Northeast Louisiana
to begin the 12z TAF period. Prevailed -TSRA at the MLU terminal
for the first couple hours of the TAF period with VCTS at LFK for
the same period of time. Otherwise, believe any new convection
will have to await daytime heating today. Again, based the 12z TAF
package on the latest HREF output which has had a far superior
handle on current and past trends. Reintroduced VCTS at all
terminals beginning at 17z and continued through 01-02z this
evening. There are some indications we could see some nocturnal
convection again overnight tonight near the I-20 Corridor
confidence and/or lack of storm coverage will preclude any mention
in this TAF package for now. Look for mostly variable winds today
with speeds generally under 10kts except stronger and gusty near
thunderstorms.

Although spotter activation is not expected today, spotter reports
may be needed once again with the threat of isolated severe storms
continuing through at least this evening if not into the overnight
hours.
