.DISCUSSION...
Issued at 119 PM CDT Sat May 30 2026

High latitude blocking with an anomalously strong upper ridge
over central Canada will continue to result in dry conditions
the rest of this weekend and much of the upcoming work week. Sfc
high pressure to our north will continue to result in winds off
the lake through midweek, resulting seasonably cool weather
near the lake. Meanwhile, inland temperatures are expected to
generally remain above average through the upcoming workweek.

Upper trough moving out into the Plains today will run into this
upper ridge, and its eastward progress will likely become
stunted. Some modest height falls are expected along the
southern flanks of this upper ridge across the Midwest, but
precipitation should struggle making east of the Mississippi
River as it encounters very dry low level easterly flow. Did
hang on to some slight chance pops for showers Sunday night west
of I-39, but suspect even those very low pops may be too high.

High latitude ridging is finally progged to break down late in
the upcoming work week as a vigorous northern stream trough
tracks east across southern Canada. This should eventually allow
a cold front to sag southward across the Great Lakes and into
our area by next weekend. Ahead of that front, winds will likely
finally turn offshore later this week bringing the summer-like
warmth to the lakefront. This will be followed by an increased
chance of at least some showers and thunderstorms by next
weekend.
