Brightening for Late Work Week...

There still were a lot of lingering clouds across Minnesota yesterday (see infrared loop from College of DuPage Satellite and Radar Menu), but St. Cloud got through the day dry for the only the third time in the past 10 days. High temperatures didn't get much beyond where they were on Tuesday, topping out in the lower 60's (see 3-day loop of high temperatures from NWS/University at Albany). The low level clouds have eroded a bit more overnight, but temperatures have remained in the 40's to near 50 (see UCAR Minnesota surface chart).

Our warming trend will finally return us to near average temperatures for late May, meaning that we will see temperatures climb back into the 70's over the next three days. That doesn't guarantee dry days, however. A warm front will approach Minnesota this afternoon, so there will be a chance for scattered showers and thunderstorms this afternoon and especially overnight. The chance won't be huge, however. We should see more sunshine than we have during most of the work week thus far.

Tomorrow should be a gorgeous day and, unfortunately, the best day of the long weekend most likely. After a few morning clouds, we will break out into sunshine and temperatures will climb well into the 70's.

By Saturday, however, the slow moving storm now moving across southwestern Canada will begin to push southeastward. This will trigger a lot of afternoon clouds with a chance for scattered showers and thunderstorms. Highs will be able to make it into the 70's again, but it won't be as bright and sunny as on Friday.

...But More Showers Over the Weekend

It now appears that the cold front from this system will push through Minnesota late Saturday, and the upper-level low will follow the front, moving into Minnesota for Sunday and Monday. That will create a lot of clouds, cooler temperatures, and the chance for occasional rain or showers. The most likely time for rain will be Sunday midday through evening. Temperatures will be knocked down to the 60's both Sunday and Monday.

Again, the showers I am forecasting will be scattered and relatively brief. So, I wouldn't cancel any outdoors plans, but I would be prepared for some periods of rain during any outdoor activities.
