In fact, October saw the largest number of days above normal for high temperature since last November and made for the eight month in a row where there were more than 15 days above average for high and low temperature. Based on IEM calculations, this is only the third time on record for Des Moines to have such a streak last eight months (1987 and 2006). November looks to start off on the cool side with mostly dry weather expected. > NWS Watch/Warning Summary for 01 Nov 2010 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 0 0 | 0 0 0 0 0 | 0 Svr Tstorm 15 0 | 0 0 0 0 0 | 2 Fl Flood 1 0 | 0 0 0 0 0 | N/A ARX = LaCrosse, WI DVN = Davenport, IA DMX = Des Moines, IA OAX = Omaha, NE FSD = Sioux Falls, SD > IEM Cow Report SVR+TOR Warnings Issued: 13 Verified: 6 [46.2 %] Reduction of Size Versus County Based [81.8 %] Average Perimeter Ratio [17.3 %] Percentage of Warned Area Verified (15km) [21.1 %] Average Storm Based Warning Size [1013 sq km] Probability of Detection(higher is better)[0.83] False Alarm Ratio (lower is better) [0.54] Critical Success Index (higher is better) [0.42] -------------- next part -------------- An HTML attachment was scrubbed...

The quality controlled Iowa COOP data for March 2010 has been uploaded to the IEM. These observations are kindly provided by Harry Hillaker, our state climatologist, who passes along these notes on the month:

March temperatures averaged 37.9 degrees or 1.9 degrees above normal while precipitation totaled 1.87 inches or 0.34 inches less than normal. This ranks as the 41st warmest and 63rd wettest March among 138 years of state records. Snowfall averaged only 2.1 inches or 2.7 inches less than normal to rank as the 23rd lowest March total among 123 years of records. Nevertheless this meager total pushed the seasonal total up to 49.2 inches or up to a tie for the sixth highest seasonal total of record and the highest for any winter season since 1978-1979.

The following is the number of new daily records set at COOP sites based on data back to 1951.

The featured chart presents the number of days for the past 31 years that the high was above either 60 or 70 degrees for November at Ames. This year has seen two days over 60 with none over 70 for Ames. Our recent history shows that days over 70 in November were rare in the 80s and 90s.

Warmer weather is expected today, but only to reach average values for this time of year. This weather is a far cry from 70s reached just 10 days ago.

The featured chart presents the high and low temperature for Thanksgiving's past at Des Moines. This should be the coldest day since 1995 and only warmer than way back in 1985. Another big story are the driving conditions over the upper midwest with icey and snowy expected to cause travel difficulties. For Iowa, these impacts look to be limited over the northern half of the state.

For Ames, this made for the first such day this fall. Having such a day does not mean cold despair for the rest of the year as illustrated by the featured chart. Even after the first frozen fall day, temperatures many times still nicely warm sometime before 31 December. Highs on Sunday were a case in point as values soared into the 50s.
