issued at 224 am edt fri jul 10 2026
widely scattered convection associated with a mid level shortwave
and corridor of higher theta-e will exit off to the east by daybreak
leaving primarily dry/humid conditions for the bulk of the morning
and early afternoon. diurnally driven, isolated to scattered,
convection then once again redevelops this afternoon into early this
evening in the vicinity of a subtle low level boundary and/or
convective outflows drifting slowly south into a moderately unstable
air mass (~2000 j/kg of cape). the overall weak forcing/shear/flow
will not be conducive to storm organization, leaving localized
flooding and pulse-type wind gusts to 40 mph as the primary threats.
the southward sagging front will force the primary instability axis
south of the area later friday night into saturday with the bulk of
the area dry and less humid. there remains mixed signals in
available model guidance on if the northern fringes of a mcs
tracking east through the mid ms/oh river valleys clips our southern
zones during this time. opted to retain a slight chance pop south of
us 30 in in and south of us 24 in oh.
an anomalously strong and expansive mid-upper level ridge remains on
track to build east over the north-central us and midwest sunday
through the middle of next week. this will put a lid on any rain
chances with highs expected to reach the low-mid 90s by tuesday-
wednesday. afternoon heat indices may make a run at 100 by this
time, though humidity levels look less impressive when compared to
our previous heat wave. low chances (20-30%) for convection then by
the end of next week as ensembles tend to flatten the ridge
somewhat.

issued at 1236 am edt fri jul 10 2026
widely scattered storms will remain possible through 09-10z with
brief ifr/mvfr vis restrictions possible (currently seeing this
at ksbn). weak mid level shortwave and deeper moisture will exit
off to the east by daybreak with dry conditions anticipated
through the early afternoon. retained an mvfr group at ksbn
10-16z as some stratus/br may attempt to fill in given light
winds, late clearing and moist low levels. moisture/instability
axis will linger over northern in this afternoon with diurnally
driven, scattered, convection redeveloping.
