February Frozen Days

02 Feb 2018 05:34 AM
The calendar day high temperatures on Thursday failed to breach the freezing level making for a frozen day. The featured chart looks at the frequency of such days during February for Ames. The labels on the bars are the actual number of years over the period of record that the high was below 32 degrees. Of course, Feb 29th shows up a bit funny as there have been one quarter as many of those days than others in February. The slope is downward going from just over 50% to start the month to under 30% by the end. So such days become less common as we slowly inch toward spring!

Warmer March in store?

15 Feb 2011 05:55 AM
The past few days of much warmer weather has helped to eliminate much of the snow that has stuck around for most of winter. The featured chart looks at the relationship between having snow on the ground of a given day in February and then the average temperature that following March. The implication is clear, getting rid of the snow now leads to a few more degrees warmer weather in March. The chart also shows that the coldest, on average, March temperatures are when there is snow at the end of February and the warmest are when there is no snow at the beginning of the month.
