Temperatures are expected to warm nicely today and Friday, perhaps reaching 70+ degrees.

Temperatures on Thursday were in the 70s, which is doing rather well for mid October. The featured chart presents the frequency of having the 3 PM CDT (2 PM LST) in the 70s. For October, the value is around 20% meaning that one in five days experience temperatures this warm. September and June are practically tied for the highest percentage, so if this type of weather fits your fancy than those are your favorite months.
Today is the long anticipated day of very warm weather with highs expected into the 70s for much of the state. The featured map presents an analysis of the average first date of 70+ degrees each year and those locations that have already hit that level this year denoted with a x. The eastern half of the map is where the persistent cold and heavy snowfall has occurred this year and you can see how far behind they are with hitting their first 70, by about two weeks. Hitting 70 today would be about normal for areas in the teal color. Minneapolis would be one such area.
Strong winds helped boost temperatures to wonderfully warm levels on Sunday with Des Moines topping out over 70 degrees. The featured chart presents the frequency of having a second 70+ degree day afterwards. For the end of March, the frequencies are below 50%. The higher frequencies shown earlier in March are simply due to a limited number of events. Of course, the highest values are in July when each day is almost guaranteed to be at least 70 degrees.
High temperatures today are expected to soar into the low 70s for much of Iowa. The calendar does now say November, so one may expected the staying power of such warm temperatures to be fleeting. The featured chart presents the frequency of having a day above 70 followed by another day over 70 by each day of the year. As shown by the chart, the chances for early November are not good. Indeed, temperatures will fall back into the 40s tomorrow as the warm up will be brief!
