The Sunday afternoon high temp at Minneapolis-St. Paul International Airport was 64 degrees. Our average high is 59 this time of year. A cold front will move through the metro area Sunday evening, accompanied by some periods of rain.

Much of central and southern Minnesota, plus western Wisconsin, will have periods of rain Sunday evening. In northeastern Minnesota and parts of north-central Minnesota, the rain will change over to snow at some point Sunday evening. The snow will then continue in sections of northeastern Minnesota overnight Sunday night.

Plotted gusts are in knots, with 19 knots equal to almost 22 mph.

Back to temperatures, Twin Cities metro area highs are projected to be in the mid 40s on Tuesday, followed by upper 40s Wednesday. Our highs rebound to around 60 degrees for Thursday and Friday.  

Twin Cities highs retreat to the 50s next weekend, and cooler than normal temps may linger into the beginning of the following week. The NWS Climate Prediction Center shows a tendency for below-normal temps in Minnesota and Wisconsin for April 24 through April 29:

I should mention that our average Twin Cities high temp is 64 degrees on April 29, so even a high of 60 would be a few degrees below-normal by the time that we reach the final few days of April.
