Rain will gradually taper off from west to east tonight.

Look for a clearing trend after a chance of some morning fog.

A fresh puff of dry comfortable Canadian air will deliver a spectacular day on Wednesday! Look for highs in the 70s north to near 80 south, with a fresh northwest breeze at 10-20 mph and plenty of sunshine!

PH

Update 4:15pm:

A band of showers & T-Storms continues to slide east through Minnesota through this evening. So far the storms have been pretty tame, garden variety rain producers.

The strongest storms will stretch from near Duluth southward along I-35 through 6pm.

1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 raddy tue.gif

Severe weather parameters are running pretty low, and a good batch of debris clouds ahead of the system is likely to prevent any kind of widespread severe outbreak.

Still, a warning or two is possible with some of the stronger storms.

Expect a few scattered showers and T-Storms in the metro this evening, but the threat for severe storms seems to be diminishing at this time.

PH

Update 2:55pm:

Storms are still very tame on doppler, and no indications (mesoscale discussions) of a watch from SPC yet. Strongest storms heading for Lake Mille Lacs may produce some .50″ hail along with heavy downpours and lightning.

A few garden variety showers & storms will enter far west metro in the next hour, but they do not look severe at this point.

NWS discussion below.

Update 2:20pm:

Our cold front is on schedule today, and it’s sparking some scattered storms in central Minnesota.

So far there are no watches or warnings, and the storms have been fairly tame. But they are producing heavy downpours with some gusty winds and lightning.

It still looks like the best window for metro storms will be between 4pm and 7pm tonight.

SPC maintains a slight risk for severe storms in Minnesota through tonight.
