Wind roses are a wonderful graphic tool to provide wind climatology. The saying "a picture is worth a thousand words" definitely applies to these plots:

These plots are available for each of the automated airport sensors in the ASOS and AWOS networks by pre-generated or custom generated requests at the linked URL. Each day, a script reprocesses these plots for a different state in the United States based on the stored archive of data here at the IEM. This process is intensive, so we can't simply reprocess every plot each day.

At this time, these pre-generated plots are not being generated for non-United States sites. Our archive of data for these sites is not backfilled enough to make this happen. At some point, the backfilling will occur, but it is a low priority item at the moment. > Daily Feature +---------------------------------------------- http://mesonet.agron.iastate.edu/onsite/features/cat.php?day=2011-10-18 | Title : Some have yet to see cold | Date : 18 Oct 05:56 AM | Votes : Good: 15 Bad: 1 +---------------------------------------------- The minimum temperature so far this fall has been on the warm side of average with many locations yet to experience a sub freezing temperature.

A long standing bug with the IEM was the assumption of all data to be in central standard/daylight time here in the US. Well, now that we are processing data from most anywhere in the world, this assumption caused problems when computing summary data like daily high and low temperature.

Over the past week, I believe I have added proper support for presenting data in the local time zone and computing daily summary values for the local time zone as well. For example, the referenced link will show currents for Germany in their local time zone with summary data valid for that local day.

Unfortunately, there does not appear to be an authoritative database of local time zones for observations sites, so some fudge work was done in places.

This support is also useful for supporting observation sites here in the midwest which are either in mountain or eastern time.

As always, please let me know of troubles you see. > Daily Feature No feature posted > NWS Watch/Warning Summary for 23 Oct 2011 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 0 0 | 0 0 0 0 0 | 0 Svr Tstorm 18 0 | 1 0 0 0 0 | 0 Fl Flood 0 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: 11 Verified: 4 [36.4 %] Reduction of Size Versus County Based [61.1 %] Average Perimeter Ratio [48.8 %] Percentage of Warned Area Verified (15km) [13.2 %] Average Storm Based Warning Size [2065 sq km] Probability of Detection(higher is better)[1.00] False Alarm Ratio (lower is better) [0.64] Critical Success Index (higher is better) [0.36] -------------- next part -------------- An HTML attachment was scrubbed...

The quality controlled Iowa COOP data for January 2011 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:

January 2011 temperatures averaged 14.5 degrees or 4.9 degrees below normal while precipitation averaged 0.93 inch or 0.01 inch more than normal. This ranks as the 36th coolest and 69th wettest January among 139 years of records. Snowfall averaged 11.3 inches or 3.6 inches above normal to rank as the 18th snowiest January among 124 years of record. Temperatures varied from a low of -30 degrees at Elkader on the 21st to highs of 45 degrees at Shenandoah and Sidney on the 6th and at Glenwood on the 28th. A few northern Iowa locations never warmed above freezing during the month. The 45 degree statewide maximum temperature for the month has been lower only three times, 42 in Feb. 2010, 40 in Dec. 1983 and 40 in Jan. 1979. The result was very little snow melt during the month with Spencer reporting 20 inches on the ground at month's end.

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

> Daily Feature +---------------------------------------------- http://mesonet.agron.iastate.edu/onsite/features/cat.php?day=2011-10-28 | Title : Can't catch 1966 | Date : 28 Oct 05:55 AM | Votes : Good: 20 Bad: 4 +---------------------------------------------- So far, Des Moines has had its 12th driest meteorological fall on record. The featured chart presents the precipitation rank to date since the first of September for this year, 1914 (the wettest year) and 1966 (the driest year). If we got no precipitation for the rest of the season, our fall total would still be a bit higher than 1966 and coming in second lowest. The forecast has some chances of rain in the forecast next week. > NWS Watch/Warning Summary for 28 Oct 2011 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 0 0 | 0 0 0 0 0 | 0 Svr Tstorm 0 0 | 0 0 0 0 0 | 0 Fl Flood 2 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 No Warnings Issued -------------- next part -------------- An HTML attachment was scrubbed...
