Last March /2013/ did do an about face on March of 2012 with colder than normal readings across the region but NOTHING like this March as temperatures just averaged a couple of degrees below normal.
Note where the March temperature places thus far as of the first day of spring and in spite of our "mild spells"recently. I think what is most amazing in the metro Detroit area is that this March's average temperature thus far is about half of what it was two years ago for March. In other words, we had twice the heat in March 2012 than we've had thus far this March! Think that's bad; it gets worse in the Flint and Saginaw areas. If one doubles Flint's March average temperature /22.7/ it still wouldn't be close to the 49.5 reading of two years ago. Same at Saginaw with an average temperature 22.1, doubling that would give a 44.2...a far cry from the 48.0 degrees in 2012! Another mind blowing item is that the range from the record warmest March to this record cold March thus far is 25 degrees at Detroit! Flint is even wider with 28.3 degrees from warmest to coldest while Saginaw is 25.9. And, excepting for Flint, both Detroit and Saginaw this has happened in the last two Marches!
The anomaly temperatures at 850 MB /5kt/ displayed here in C /Celsius/ for the middle of next week are forecast to be around -15C below the norm.
The map below displays similar Analogue dates & years for the upcoming cold snap at this time of year along with the height departures for above (red) and below (blue) departures. Note late March - early April 1982 one of our season(s) analogues shows up again and is also among them for this time period /19820405, displayed on the lower right/
Try to hang in there because, as evidence by just the past few Marches and springs, this time of year the weather is extremely fickle and changeable. On average, the more typical gradually warming spring weather has been delayed about a solid month (when looking at the three month meteorological spring /Mar-May/ and not the calendar). And; with the turn of the calendar month comes the promise of warmer weather.
