Brighter on Tuesday; rain chance Wednesday afternoon

You can think of Monday's weather as a speed bump in our cruise through April.

The official high temp was 53 degrees at Minneapolis-St. Paul International Airport on Monday, but it occurred at 1 in the morning!

Twin Cities temps were in the 40s during the daylight hours of Monday, and temps dropped into the 30s by late afternoon. It was also a breezy day, with some scattered showers and drizzle at times.

That was quite a change from the 70s of this past weekend!

Overnight flakes   

Rain or a mix of rain and snow Monday evening is expected to change to mostly snow in east-central Minnesota overnight.

A quick changeover to snow Monday evening allowed 1 to 2 inches of snow to accumulate in parts of the northwest and north metro.

Some streets and roads could become slick as temps drop overnight.

Sunshine and warming temps will melt much of the snow Tuesday afternoon.

A lingering flurry is possible very early Tuesday morning in parts of eastern Minnesota, then skies are expected to brighten by late morning.

You might impress your friends with these snow facts:

1) We average 2.5 inches of snow during the month of April in the Twin Cities metro area.

2) April of 1983 was the snowiest April in Twin Cities weather records, with 21.8 inches of snow!

Any snow that accumulates overnight in the Twin Cities will melt on Tuesday.

Northwestern Wisconsin could see a couple of inches of snow and patchy freezing drizzle Monday night and early Tuesday

The National Weather Service has issued a winter weather advisory until 7 a.m. Tuesday for northwestern Wisconsin:

Minnesota could also see some showers and isolated thunderstorms Friday evening into Saturday morning.

Better satellite images

NOAA's newest weather satellite, GOES-16, is undergoing testing and it's sending us some very high resolution images:

GOES-16 provides us with higher resolution satellite pictures and more images per hour than previous weather satellites.

That's great news for weather forecasters, public safety agencies and anyone fascinated by weather.

NOAA has posted some details of the GOES-16 testing phase.
