Spring 2012 Review...Warmest Spring on record for some

 

 

     The historic heat wave in March set the tone for the rest of the spring, with all the Spring months coming in well above normal for temperatures.  The final numbers confirm as such, with several locations reporting their warmest Spring on record since reliable records began.  Even those that did not set a record reported one of their top three warmest Springs.

     Precipitation varied across the region. In general, the least precipitation occurred across Eastern Upper and Northeast Lower Michigan, where amounts averaged below normal. Elsewhere, rainfall averaged near to above normal, with Traverse City recording an exceptionally wet Spring.

    Despite the record warm temperatures, snowfall was well within the realm of normal.  However, most of this occurred with the early March severe winter storm, with snowfall averaging well below normal from the second half of March onward.
