Pattern looks to remain dry with no significant weather indicated.
Temperatures will be the primary forecast concern during the
period.

Low pressure over west central Alberta at 20z will track southeast
across the prairie provinces and north of the Great Lakes into
eastern Canada through Wednesday. This system will drag a cold
front into the northern plains on Monday and into the lower
Missouri Valley by Tuesday morning. High pressure will then build
into the region Tuesday and Tuesday night before moving southeast
on Wednesday.

Alternating temperature pattern will occur during this time with
warm air building in through Monday ahead of the cold front then
cold air and windy conditions behind the front for Tuesday and
Tuesday night. Warm air returns on Wednesday as the upper pattern
amplifies over the country with ridging over the western half of
the nation and troughing in the east.

Long term...(wednesday night through sunday)
