Slow Improvement Through Mid-Week
Pesky Low to Hang Around One More Day
The low pumping all of the moisture over Minnesota has finally arrived in Minnesota overnight (see water vapor loop from College
of DuPage Satellite and Radar Menu). Over the past week, this system has dropped between 2 and 5 inches of rain in much of central Minnesota (1.47 inches at the St. Cloud Airport; NWS will update this map later this morning) with much more in the northwestern Twin Cities and in south central and southeastern Minnesota. The rain has slowed down, but the persistent clouds have remained over Minnesota (see infrared loop from College
of DuPage Satellite and Radar Menu) with rain showers lingering across northeastern Minnesota. The flood warnings have continued in south central and southeastern Minnesota.
The upper low is getting stronger as it moves through Minnesota, but the good news is that it will drift southeastward during the next two days. That will be far enough away for us to see some improving weather during this work week. I think today will be the last day of completely cloudy weather. The air will be slightly more stable, so I only think there will be some spotty showers or sprinkles this afternoon, instead of the persistent rain. Late tonight, the storm will have moved far enough away to allow us to see some clearing. Tomorrow, we could actually see some morning sunshine before skies cloud up completely in the afternoon. By Wednesday, we could finally have a good supply of sunshine.
Highs will be in the 60's today and only around 60 tomorrow. All of the clouds will keep the lows in the 40's. There will also be a strong wind, so the combination of clouds and wind will make it feel much cooler than we are used to.
Sunshine by Mid-Week and Lingering For a While
This low is actually forecast to stall out across the Southern Appalachians for the bulk of the week. The strong low will block the advance of any other weather systems. This will be good news for Minnesota since the low is expected to move far enough away to allow us to stay in the sunshine, starting on Wednesday and continuing through the (don't jinx it) weekend. As sunshine returns, highs will likely return to the seasonably middle to upper 60's for the end of the week and could be in the 70's over the weekend.
