Weather Shocker: May snowfall

1 84 hr snow north.PNG

84 hour NAM snowfall forecast shows a potential swath of 4″+ from Bemidji to Hinckley to Rice Lake.

You knew the other shoe would drop.

All indications are that our record mild spring is about to take a wintery detour.

A potent low pressure system is heading for the Upper Midwest Thursday into Friday. This one brings a cold rain to much of the state. All indications are that the rain will be so cold it will fall as snow in North Dakota, northern Minnesota and northern Wisconsin.

Expect rainfall to spread from west to east Thursday. It looks as if rain will reach the metro by evening rush hour. The good news is that many locations could see an inch of rain by late Friday. Temperatures will not climb out of the 40s for most of Minnesota Friday.

The system will drag along enough cold air aloft to change rain to snow for much of northern Minnesota by Friday night. Indications are anywhere from 2″ to more than 6″ of heavy wet snow could fall along a line from Bemidji, to Hinckley to Rice Lake. Enough cold air may mix in Friday night that a few wet snowflakes could fall as far south as the metro.

Get ready for a weather shocker over the next 72 hours!
