isolated showers may dot southern and eastern reaches of the
forecast area today. a stationary front remains draped across
central indiana and weak impulses continue to pass by aloft.
overall, plenty of dry time today with decreasing clouds late
in the day. enjoy today`s highs in the 70s because the heat is
on beginning with highs in the low- to-mid 80s sunday.
as written extensively in this space these last few days, becoming
very hot and humid for the week ahead. a 594dm ridge amplifies over
the southern mississippi valley, eventually translating east through
time. high confidence in highs in the 90s and heat indicies near 100
degrees monday through at least thursday/friday. before
breaking down late week, the ridge appears strongest tuesday
through thursday, representing our hottest days of the week.
i`ve tested the waters for heat headlines this morning, but the
appetite wasn`t there from neighboring offices. primarily dry
during this period, but as the week progresses we`ll monitor for
thunderstorm chances.

while ceilings have improved for the moment at kfwa, ceilings
around the area are hovering near mvfr and ifr. guidance
suggests this area of stratus will gradually ease later this
morning. medium confidence at best with how stratus evolves. i
did remove the -shra mention as activity appears to be quite
isolated today and now favoring areas south of kfwa. with this
pesky boundary still in the vicinity tonight, will need to
consider the possibility of patchy fog. like the showers, it
appears the best area of visibility restrictions may be south
of kfwa.
at ksbn, lesser concerns due to their placement away from a
stationary front. steady east wind and high confidence in vfr
conditions today.
