Finally, a dry day!

25 Jun 2010 06:04 AM
Thursday was finally a day without rain in the state and interrupted a very wet period. The featured chart displays the statewide averaged daily rainfall as estimated by the IEM since 1 May. While values may not appear to be very large, once spread over the entire state it equates into a lot of water! Friday is expected to be mostly dry until later in the afternoon when thunderstorms are expected to develop and stick around into Saturday.

Quite hot for May

26 May 2010 05:09 AM
This past Sunday and Monday saw high temperatures over 90 for most of the state and lows around 70. For May, these two days were some of the warmest on record and the warmest for days prior to 25 May as shown by the featured illustration. The two days were also exceptional for having low temperatures above 70, which was only the sixth time that has happened in May dating back to 1893. All of these values are statewide areal averages computed by the IEM.

Day 5 of 6 below 60 degrees?

11 May 2010 05:13 AM
The featured graph of daily high and low temperatures for Ames shows a period of six days with the high temperature below 60 degrees. A model's forecast for today and tomorrow have yet to verify, but if it does, this period would tie a record for consecutive days below 60 in May. The last time this has happened in Ames was all the way back in 1931. Wet conditions will also persist with even heavier rain expected by the end of the week.

A bit frosty for May

10 May 2010 05:10 AM
Clear skies and calm winds helped temperatures to drop to frosty levels Sunday morning as shown by the featured IEM analysis of low temperatures. The full impacts of this cold event will take a bit to be determined, but the corn crop was probably not far enough developed to be significantly impacted. Trees and flowers took the brunt of this cold weather with more cool weather expected this week. The big story will be the heavy rainfall along with highs only in the 50s for the next few days.
