March Lamb: Extended thaw next week

CPC 6-10 day outlook highlights strong possibility of above average temps for the first week of March.

Get ready to dodge some huge puddles.

A weak lazy ridge of high pressure will build in over the Upper Midwest next week allowing afternoon temperatures to soar above freezing for several days. It appears at least 5 of the next 8 days could feature afternoon temperatures above freezing.

Forecast modles hinting at 30s next week. I would not be surprised to see mid to upper 30s late next week.

The warmest stretch appears to be late next week. As high pressure sprawls over the region, increasingly powerful March sun should boost temperatures into the mid to upper 30s each day. Though deep snow cover will work against skyrocketing temps, it's possible that some areas could make a run at 40 by late next week.

Snow pack takes a hit:

The thaw and higher March sun will melt some snow next week. As of Friday morning, 12" of snow is on the ground at Twin Cities International Airport. If we melt an inch every day or two, that number could be down to 6" or 7" in the metro by next weekend.

Pothole warning:

Our early pothole seasons will get much worse in the next two weeks. With daily freezes and thaws, any loose pavement is going to get broken apart in the next week or so. Watch out for some gargantuan potholes next week.

Air quality alerts?

Weak high pressure means light winds next week. That will allow stagnant air to collect pollutants as the week wears on. It's possible that air quality will deteriorate to the point that MPCA will have to issue air quality ad ivories next week.

The good news is it appears our weather pattern is taking a slow turn towards more spring like conditions. There will no doubt be more snow, but right now it appears the only system capable of dumping snow may pass south of Minnesota on or near March 8th. We'll still likely get another shot or two of chilly Canadian air to remind us it's not spring just yet, but I think it's safe to say the worst of winter like conditions are behind us now.

Right on schedule and not a moment too soon for many Minnesotans.

Enjoy the warm up!
