A slow moving upper level disturbance will generate numerous rain
showers and a few thunderstorms into early tonight. Conditions
will gradually improve Sunday into Monday though as this low

Upper low just south of KFWA beginning to lift out toward KDET by
daybreak Sunday. Vast majority of shower/isold thunder had drifted
westward from nw IN through ne IL. Clearing within ern/nrn
quadrant of upper low continues to slowly destabilize and expected
to continue to fill in.

Otherwise showers will diminish this evening and will minimized pops

Secondary disturbance wrapping sewd through lower MI tomorrow had
trended even farther north in latest 12Z model solutions and have
cut pops further.

Issued at 223 PM EDT Sat Oct 1 2016

Upper low lifts out through New England on Monday with rapidly
building upper ridge in its wake across the lakes. Vigorous low
level thermal ridge builds in earnest thereafter...peaking Wed-
Thu. No suprise to see additional eastward slowing of upstream sys
ejecting out of the wrn US given intense Hurricane Matt working
north along the se coast. 12Z solution scope somewhat varied with
wrn energy splitting and frontal wave developing through the mid
MS valley Thu the primary trend noted. Will generally rely on a
blend later periods. Temps returning to well above normal by Tue.
