Isolated to scattered coverage of showers and thunderstorms are possible in northeast Minnesota and northwest Wisconsin on Monday, mainly during the morning and afternoon.
Higher instability (mostly elevated CAPE) will advect eastward into the Northland on Monday while a warm front moves ENE out of western Minnesota. Lift associated with the advancing warm frontal boundary, combined with warmer and more humid air advecting into the Northland should be enough to produce isolated to scattered coverage of showers and thunderstorms on Monday. Note: The threat for severe thunderstorms is on the low side on Monday with a Marginal or Level 1 risk for an isolated severe thunderstorm with wind and hail being the main threats along with lightning and downpours which will occur in any thunderstorm.

Not looking at a whole lot of rain or widespread rains on Monday with rainfall totals generally in the trace to quarter inch range, but where thunderstorms occur heavier rainfall totals will be possible.

A dry air mass currently over the Northland this afternoon will be replaced by somewhat more humid conditions by Monday afternoon as dew points climb into the 50s and lower 60s, but this more humid air mass won’t stick around long as drier air moves back in come Tuesday.
A rather large temperature contrast appears to be setting up Monday afternoon with a very warm to hot air mass covering western portions of Minnesota while cooler weather will be found in northeast Minnesota and northwest Wisconsin. Note: Near 80 degree temps should return in Duluth on Tuesday as winds shift from east on Monday to west on Tuesday.
