"Here Comes the Rain Again"
Add in some sunshine and take the wind down a few MPH and seasonably cool conditions can feel rather pleasant. We only had a few clouds to dim the sunshine yesterday (see infrared loop from College
of DuPage Satellite and Radar Menu), so high temperatures in the lower half of the 50's (see UCAR 4 PM surface chart) felt pleasant. This morning isn't quite as cool as yesterday morning so far (St. Cloud's coolest morning of the season so far with a low of 27 degrees; see NWS: Last 72 hours of St. Cloud Observations). Temperatures have been hovering in the 30's for a good chunk of the night (see UCAR
Minnesota surface chart), but the high clouds and east winds have helped to keep temperatures up a bit. The exception is along the Iron Range and the Boundary Waters where temperatures have again fallen into the 20's. Perhaps we will see Embarrass or some other town drop below 20 degrees once again.
However, the increase in high clouds is a sign of our upcoming weather. Swept up in the southwest winds ahead of the strong storm off the British Columbia coast is a storm system in Arizona (see water vapor loop from College
of DuPage Satellite and Radar Menu),that will be pushed into the Dakotas and Minnesota by tonight. There is a decent amount of moisture in Oklahoma (total precipitable water of three-quarters of an inch to a bit over an inch on the College of Dupage PW chart) with this system, so this storm has the potential of producing a soaking rain over Minnesota from late this afternoon until the early morning hours tomorrow.
Thursday will be a brighter day. We'll begin with some thick frost and temperatures in the lower 30's, but see readings climb back above average into the upper 50's in the afternoon.
As a series of storms continues to affect the West Coast, another storm system will get caught up in the southwest flow to the east of it and push towards the Northern Plains by Friday. We will see some warmer air pumped in for a while, followed by a cold front passing Friday evening. However, it looks like there will be far less moisture available for this Friday storm, so I only have a chance of some scattered rain showers late Friday or Friday night. Highs will climb into the 60's with at least partial sunshine.
Cooler air will push in behind the cold front and that cool air will be unstable. So, we will have sunshine mixed with a lot of clouds on Saturday. Highs will be limited to the low to middle 50's and there will be a strong northwest wind. We could see a chilly low Saturday night, with temperatures bottoming out in the 20's or near 30 on Sunday morning, then another warm up will begin with readings moderating into at least the middle to upper 50's on Sunday and possibly warmer on Monday.
With the strong storm off the West Coast, heavy rain is possible this week with the highest mid-week rain totals likely along the northern California and southern Oregon coast.
