Rain is most likely in northeast Minnesota and northwest Wisconsin, including Duluth, from Thursday evening into the overnight, with a chance it could stick around into Friday.
The chance of rain comes from a cold front pushing east from the northern Plains, along with a strong low-pressure system moving northeast out of the Dakotas.
There’s a chance for some thunderstorms in parts of the Northland Thursday evening, with computer models showing elevated CAPE (instability). However, the risk for severe weather looks pretty low at the moment.
The Euro model indicates a faster arrival of rain on Thursday evening.
The RRFS model indicates a slower approach of the rain, which is something the computer models will need to work out over the next few days.
Rainfall of about 0.1 to 0.25 inches or more is possible across northeast Minnesota and northwest Wisconsin from Thursday through early Friday.
