Big October Warmup

19 Oct 2018 05:32 AM
Temperatures warmed nicely on Thursday after a chilly start to the morning. The day made for a near perfect fall weather in the state.

The featured table presents the top 10 largest differences for the daily high and low temperature during October for the site. This site only has data going back 30 years, but still it is fun to see yesterday crack the top 10 for largest differences.

October Precip and Snow

16 Oct 2018 05:33 AM
Getting a bit of snowfall during October is not all that uncommon as shown by the featured chart comparing October snowfall totals with total precipitation for Des Moines. Of course, getting snowfall this early in October is a bit rare and we are already well above average for precipitation amount for the month. The long term average snowfall is just 3 tenths of an inch, so hopefully we stay below average for the rest of the month! The current forecast looks dry for at least the coming week, which is much needed to help farmers again make some progress with the harvest.

Hour of New Minimum

10 Oct 2017 05:34 AM
Some of the coldest air of the season arrived over Iowa overnight. A number of locations will likely set new fall minimum temperatures. The featured chart looks at the hour at which and the new minimum fall temperature that was reported during October for Des Moines. Of interest are the very few number of reports between noon and 6 PM. This shows that it is very difficult to set new fall minimum lows during the afternoon hours as it is difficult to get very cold air into the region when even minimal amounts of sunshine can provide some heating. It will be interesting to see if this situation can happen today with very cool temperature expected this afternoon for places like Des Moines.

70+ in October

15 Oct 2015 05:35 AM
High temperatures again warmed nicely into the 70s for much of Iowa on Wednesday. The featured chart shows that with each passing October day, these events become less frequent! In fact, it is interesting to see the frequency reverse from above 80% to start the month to around 20% to end it. The middle of the month is around 50%, so about half of the past 15 October's were above 70 degrees for a high temperature.

October Ranges

22 Oct 2014 05:44 AM
This has been a rather tranquil October with temperatures within a range of 40 some degrees as shown by the featured chart. The range shown is simply the difference between the warmest high and coldest low for the month. The range this October, so far, is one of the smallest on record with only 1998 (38) smaller. Of course, this October is not over yet, but the forecast only has temperatures that may extend the range a bit higher on the warm side... An interesting data point on this chart is 1925 with the minimum that year at negative 7! In fact, the last three days of Oct 1925 all had lows below 10 degrees!
