91 day coldest period
Posted: 12 Mar 2014 05:40 AM
Has the winter season already passed us by? If one considers the coldest stretch of 91
days (1/4 of the year) to be the winter season, it is likely that we are now in spring as shown
by the featured chart. It displays the 91 day lagging average temperature for this season
along with the climatological average. This year's line has stopped its decline and has
trended upward thanks to the recent warm weather. The highlighted area indicates the
coldest 91 days and it would appear unlikely that we will be able to push any lower this
month with decent temperatures in the forecast. This does not mean we are done with the
snow storms as Iowa experiences plenty of these in March and April even while the
temperatures warm. You also should not need reminding that it snowed in May 2013!
