.DISCUSSION...
Issued at 209 PM EDT Mon Sep 15 2025
Stretch of dry/warm wx will persist this week. The feature
driving this is a high magnitude upper level ridge, and its
associated stable/dry column, currently centered over the Great
Lakes. This ridge gradually flattens with time this week as
northern stream height falls eventually work east through
Ontario and Quebec with no impact locally. Light easterly winds
will persist at the sfc otherwise through mid-week on the
southwest fringe of sfc high pressure. Some very weak nocturnal
moisture flux off of Lake Erie in this regime could allow patchy
fog/stratus early tomorrow across ne IN and nw OH.
The next opportunity for rain doesn`t arrive until this weekend when
a disjointed upper level trough releases east into the region. NBM
PoPs are low, generally 20-40%, given lingering differences in the
timing/track of the upper system and frontal zone.
