Winter 2025-26 Short Range Discussion

[Chicago Storm]

guidance is all over the place with the narrow snowfall axis for tonight.

past history would tell you that the border always cashes in on this type of scenario, though.

10pm Milwaukee update

Snow is beginning to move into the region late this evening.
Area of banded snow that has been discussed over prior forecasts
is materializing from central Iowa east to the Wisconsin-
Illinois border, with lighter and more disorganized activity
apparent into west-central Wisconsin and southeast Minnesota.
Banded snow is blossoming along a band of 925-700 mb
frontogenesis that continues to sharpen to the northeast of a
developing surface low near Omaha, NE. With most pronounced
surface pressure falls apparent to the east of the low, expect
that the newly-developed surface low will track over south-
central Iowa and northwest Illinois through the overnight
period. Already beginning to play out in radar trends, this will
put our southernmost counties (particularly those near and
especially south of I-94 & US-18) in line for the greatest
banded snow potential through the overnight hours. Have thus
maintained the ongoing Winter Weather Advisory as-is, with the
expectation that the higher end of the forecasted 2 to 5 inch
totals will materialize closer to the Wisconsin-Illinois border.
Will continue to monitor through the overnight hours. Budget
extra travel time if commuting tomorrow morning, particularly
over the southern part of the area.
