.DISCUSSION...
(Today through Monday)
Issued at 230 AM CDT Tue Jun 11 2024

One more day of below normal temperatures is on tap today as
northeasterly flow continues on the south side of a 1018 mb surface
high centered over the MO/IL/KY tri-point. Expect afternoon highs
hovering in the low 80s today; quite pleasant by June standards
in the Mid-South. The aforementioned surface high looks to shift
over the Lower MS River Valley over the course of the next few
days, which will gradually increase temperatures and humidity
through the end of the work week. We should tip the scales into
the low 90s by Friday.

Moving into the weekend, strong midlevel ridging looks to set up
over the southeast CONUS. This will allow temperatures to continue
climbing into the mid 90s and maybe even upper 90s by Sunday. In
addition, a surface boundary will act as a moisture trap for much
of the Deep South this weekend, keeping the cooler, drier air
just to the north across the Upper MS River Valley. NBM
probabilities of temperatures > 90 degrees are maxed out
everywhere on Sunday afternoon with even a few low probability
pixels of T > 100 degrees. This weekend will likely be the first
instance of triple digit heat index of the year, though it`s not
looking like heat headlines will be necessary quite yet.

Midlevel ridging finally breaks down early next week, allowing
temperatures to fall back into the low 90s. Long range models are
starting to pick up on a stark plume of Gulf moisture being
funneled up the Mississippi River Valley starting on Monday
afternoon. This system does not look to have tropical
characteristics, but it does indicate a very wet start to next
week for the central Gulf Coast. PoPs are generally in the 30-40%
range Monday and Tuesday to account for model discrepancy, but
expect shower and thunderstorm activity to be on the rise early
next week.
