Sunshine returns: Nice start to the week

What is that bright yellow thing in the sky today? And where are my shades anyway?

Yes, Sunday featured several different shades of grey.

High pressure is pushing that cloudy mess east today, and other than a brief stray showers in the eastern half of MPR land things will turn sunnier and nicer to start the work week.

Summer makes a cameo by Tuesday PM & Wednesday with temps pushing 80 Tuesday and maybe as warm as 89 Wednesday afternoon with enough sun and a warmer southerly breeze. As low pressure spins through, a few scattered storms may rumble around Minnesota into Wednesday& Wednesday night.

September Preview: Summer’s strongest cool front ahead Thursday

Thursday will feel like September in Minnesota. The strongest cool front since May will push south on gusty northwest winds,

Temps may not climb out of the 60s in northern Minnesota, and highs will hover near 70 in the south Thursday into this weekend.

Lows will dive into the 40s north and maybe even in the outer metro suburbs by this weekend. Upper 30s and scattered frost look likely by the time we reach next weekend up north.

Staying Power: “Hudson Bay Low” develops into next week?

The upper air pattern over North America is radically different from a month ago.

Gone is the big Bermuda High “Heat Pump” that fried corn fields from Iowa to Ohio.

The jet stream has shifted 500 to 1,000 miles further south, and there are signs that a big, “cut off low” will develop by this weekend over Hudson Bay.

If that happens temps will remain cooler than average over Minnesota into early next week. That should be enough to keep August monthly temps below average overall through about August 22nd.

Looking at the medium range maps we have a shot at ending up cooler than average for the month of August in Minnesota. If that happens, it will be the 1st cooler than average month in 14 months, since May 2011 when MSP ran -0.9 degrees.

There are signs we may warm up a bit just in time for the Minnesota State Fair, which begins a week from Thursday.

How did that happen?
