From the thread in the main forum...

Jeff Masters has weighed in: http://www.wundergro...l?entrynum=2057

Highlights

Pellston, Michigan in the Northern Lower Peninsula is called "Michigan's Icebox", since it frequently records the coldest temperatures in the state, and in the entire nation. But the past four days, Pellston has topped out at 80° - 84°F, the first 80°F March days in their history. Yesterday's 84° reading broke the previous record for the date (55° in 1976 and 1948) by an unbelievable 29°, and was 44°F above average.
Water temperatures at the South Lake Michigan buoy were 46 - 47°F yesterday (8°C), which is about 10°F above average for this time of year, and typical of early June temperatures.

So, if we have a 30-year history of high temperatures for a particular date, we'd expect 20 of those years to be 1-sigma years, when the temperature is plus or minus 34% of average (ten colder years, and ten warmer years.) Rare 2-sigma events occur 4.5% of the time, so we should have about 16 of these per year. Even rarer 3-sigma events occur just 0.27% of the time, or just one day per year, on average. Truly extreme 4-sigma events should only occur once every 43 years. Much of Michigan, Wisconsin, Illinois, Minnesota, Northeast Iowa, and the eastern Dakota have experienced multiple 4-sigma days over the past week.

Quite a few personal weather stations in the Saginaw Valley are reporting 90 this hour. This is likely the first 90 degree temp ever recorded in March in Michigan. Hopefully one of the coop stations there was able to snag that temp.

On this day in weather history...

1952 -- Today and tomorrow 31 tornadoes touched down from Missouri to Alabama. 343 people were killed, 3600 homes damaged, and $15 million damage. Judsonia, Arkansas and Henderson, Tennessee were virtually wiped off the map.

1992 -- 6" of snow fell north of Route 6 in Indiana.

Quite the contrast in this post from IWX NWS for Wednesday March 21

Through 5 pm:

Midland - IKW - hit 88

Saginaw - HYX - hit 88

Saginaw - MBS - hit 87

Doubtful any METAR site hit 90. However, there are about 6 or 8 coop stations in this area that might have hit 90.

I think someone posted a bit back that 89 at a coop in Lapeer was the previous state record for the month of March. We'll see if that was tied or broken in the morning when the coops report.
