.DISCUSSION...
Issued at 116 AM CDT Thu Oct 29 2026

Today and Tonight

High pressure will provide dry weather through tonight. High
temperatures will range from the mid-50s to mid-60s. Low
temperatures will range from the lower 30s to lower 40s.

Friday into Saturday Night

The surface high will move east from the Great Lakes into the
Mid-Atlantic region. As this high moves away, 850 mb moisture
transport will gradually increase ahead of a slowly moving
shortwave trough embedded in the southwest flow aloft. This
system will produce showers as it moves slowly northeast through
the region. Rainfall amounts will be up to a quarter of an inch.
The probabilities for greater than this total is up to 20
percent north of Interstate 94 and 20 to 40 percent elsewhere.

High temperatures will range from the mid-50s to lower 60s. Low
temperatures will range from the mid-30s to mid-40s on Friday
night and from the lower 40s to lower 50s on Saturday night.

Sunday and Sunday night

High pressure will provide dry weather. High temperatures will
be in the 60s. Low temperatures will range from the mid-40s to
lower 50s.

Monday into Wednesday

There continues to be much uncertainty on whether systems in
the northern and southern streams will phase somewhere from the
Northern Plains into the Great Lakes. If these systems phase,
there will be cyclogenesis across the region. At this time,
this would likely take place to our west and then the low would
either track east across Upper Mississippi River Valley or north
and northeast across northern Minnesota and the northern Great
Lakes.

If these systems do not phase, there will be 2 weaker low
pressure systems. One would move to our west and north and
another would track to our south an east. With these various
scenarios, there is much uncertainty on temperatures and
precipitation amounts.

High temperatures will be in the 60s Monday and Tuesday and from
the mid-50s to mid-60s on Wednesday. Low temperatures will
range from the upper 40s to mid-50s on Monday night and from
the mid-40s to lower 50s on Tuesday night.
