-Seeing a let up in the heavier precipitation in Duluth as of 7 PM as the first wave lifts north out of the city, but additional precipitation will continue in the form of light sleet and freezing drizzle.

-Another round of moderate to heavy precipitation should affect the city between 9 PM and 1 AM, that's when there could also be a few rumbles of thunder.  What type of precipitation we get with this second wave will depend on the surface temperatures -- Anything from freezing rain, sleet to rain is expected with even some wet snow not out of the question.

-So far there haven't been too many power outages reported in the Northland with isolated outages confined to the Brainerd, Staples, Long Prairie and Sauk Centre areas in central Minnesota as of early this evening.  MNPower outage map http://outagemap.mnpower.com/external/default.html

-If precipitation remains as sleet then that would likely result in only spotty power outages the rest of tonight, but if freezing rain becomes heavier and a significant accumulation of ice occurs, then power outages could become more widespread during the night.

-Precipitation should become more scattered overnight as a dry slot works in from the SW.  Temperatures will continue to rise after midnight with 30 to near 40 degree temperatures expected in northeast Minnesota and northwest Wisconsin overnight.

-Temperatures will fall into the teens and 20s on Monday as colder air advects into the area; Snow showers will also develop on Monday with light snowfall accumulations possible.

-Travel conditions will remain poor tonight with ice covered roads.
