.DISCUSSION...
Issued at 244 PM EDT Fri Sep 5 2025

A 992mb low is swirling over northern Ontario, its cold front now
east of our area. Breezy westerly wind today subsides not only with
a loss of daytime mixing but with the 45 knot 850-mb jet departing
to the east as well. Tonight, clouds associated with a weak low
moving through the mid-Mississippi will provide some insulation
overnight helping to keep temperatures from bottoming out, but
still nearly 10 degrees below normal.

Broad troughing in remains in place through the weekend with this
large upper-low lingering over the eastern Great Lakes. Can`t rule
out lake effect showers Saturday night or Sunday as an embedded
shortwave ripples east across Lake Michigan. Duration will be
brief with high pressure quickly coming in to disturb
equilibrium levels. High pressure remains in place through the
coming week promising dry conditions (and an increasing risk of
drought). Temperatures will gradually warm back into the 80s by
midweek as the western US ridge finally tracks east.
