A small change has been made to the website navigation bar found on most every page. Instead of having two rows of links, there is now a drop down menu by mousing over the section title. I have also added a "related" section to help navigate between various rabbit holes on the website. Look for more of these to appear after I get questions on where to find stuff!

The "related" will appear like so on some page:
related

Please let me know if you have comments on this change. +---------------------------------------------- | Title : Climodat reports for other states | Date : 03 Sep 12:53 PM | Author: Daryl Herzmann | URL : http://mesonet.agron.iastate.edu/climodat/ +----------------------------------------------

I have expanded the routines and data ingest processes to now produce climodat reports for other states in the mid-west. It took 10 years just to build up Iowa's database, so this is by no means a finished product. If you see suspicious data, please let me know. The various climate pages are being updated to show products from the other states as well. +---------------------------------------------- | Title : Worldwide METAR data | Date : 03 Sep 12:48 PM | Author: Daryl Herzmann | URL : http://mesonet.agron.iastate.edu/ASOS/current.phtml +----------------------------------------------

The IEM is now attempting to process METAR data from any site in the world, whose data is available via the NWS feed we process. The ASOS currents page and download page have been updated to support the viewing and download of this data. The metadata on these sites is very much a work in progress, so please let me know of any troubles you see. Another problem yet is that the daily summary data is computed for the local day here in Iowa. At some point, I'll come up with something clever to correct this. Most people will only wish to use the download option, which provides data in UTC anyway. > Daily Feature No feature posted > NWS Watch/Warning Summary for 03 Sep 2011 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 73 0 | 0 0 0 0 0 | 3 Svr Tstorm 133 2 | 4 3 0 0 0 | 3 Fl Flood 14 1 | 2 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: 201 Verified: 84 [41.8 %] Reduction of Size Versus County Based [66.3 %] Average Perimeter Ratio [24.9 %] Percentage of Warned Area Verified (15km) [18.5 %] Average Storm Based Warning Size [1304 sq km] Probability of Detection(higher is better)[0.68] False Alarm Ratio (lower is better) [0.58] Critical Success Index (higher is better) [0.35] -------------- next part -------------- An HTML attachment was scrubbed...

The featured chart attempts to look at the relationship of having cool days along with mostly clear skies or northerly winds. While the determination of these two criteria was somewhat arbitrary, the signal appears to be reasonable.

The quality controlled Iowa COOP data for December 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:

December temperatures averaged 18.9 degrees or 3.7 degrees below normal while precipitation averaged 1.29 inches or 0.06 inch above normal. This ranks as the 27th coolest and 55th wettest December among 138 years of records. Snowfall averaged 13.5 inches or 6.2 inches more than normal to rank as the 10th snowiest December among 124 years of records. Record snow totals for any calendar month were set at New Hampton (36.9 inches) and Waukon (36.0 inches).

For 2010 temperatures averaged 48.1 degrees or 0.3 degrees above normal while precipitation totaled 45.10 inches or 11.02 inches more than normal. This ranks as the 66th coolest and second wettest year among 138 years of records. Only 1993 saw more precipitation with a statewide average of 48.22 inches. Most noteworthy was a 66.77 inch annual total at Rathbun Dam which trails only Muscatine's 74.50 inch total in 1851 for the most precipitation at one location in Iowa.

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

One way to measure the distance a temperature is from the average value is to normalize it by the standard deviation for all temperature reports for that day in history. A value of positive two would mean the temperature is two standard deviations warmer than average. By standardizing, we can compare temperatures at most any time of the year. Indeed, the lowest values on the upper air occurred with our recent cool stretch! The bottom chart simply shows the largest and smallest index value per year.

One of the detrimental factors to this year's crop was a very hot stretch of weather in July during an important crop development stage. The featured chart looks at the number of days between two key stages in the corn development based on accumulated growing degree days from 1 May. Some suggest that longer the crop stays in this sweet spot for development, the more time the plant has to cycle water and nutrients leading to a better yield. The 19 days that it took this year tied the shortest period on record for Ames. Of course, there are caveats galore to this plot as corn could have been planted earlier or later than 1 May, also could have been a shorter or longer maturity variety, and crop physiology / genetics continue to improve. > NWS Watch/Warning Summary for 27 Sep 2011 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 2 0 | 0 0 0 0 0 | 0 Svr Tstorm 49 0 | 0 0 0 0 0 | 0 Fl Flood 21 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: 54 Verified: 25 [46.3 %] Reduction of Size Versus County Based [73.9 %] Average Perimeter Ratio [23.4 %] Percentage of Warned Area Verified (15km) [19.6 %] Average Storm Based Warning Size [1328 sq km] Probability of Detection(higher is better)[0.72] False Alarm Ratio (lower is better) [0.54] Critical Success Index (higher is better) [0.39] -------------- next part -------------- An HTML attachment was scrubbed...

The featured chart presents two measures of heat stress. The top panel is the number of hours where the temperature was at or above 93 based on data from the Des Moines Airport sensor. The bottom panel presents the traditional stress degree days, which is a measure of the exceedance of 86 by the daily high temperature. For both measures, this year has been the warmest since the drought year of 1988. The largest values, by a large margin, on the chart are from the dust bowl in the 1930s. > NWS Watch/Warning Summary for 28 Sep 2011 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 2 0 | 0 0 0 0 0 | 0 Svr Tstorm 59 0 | 0 0 0 0 0 | 2 Fl Flood 22 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: 57 Verified: 16 [28.1 %] Reduction of Size Versus County Based [74.8 %] Average Perimeter Ratio [18.3 %] Percentage of Warned Area Verified (15km) [16.8 %] Average Storm Based Warning Size [996 sq km] Probability of Detection(higher is better)[0.58] False Alarm Ratio (lower is better) [0.72] Critical Success Index (higher is better) [0.23] -------------- next part -------------- An HTML attachment was scrubbed...
