It has been a long time since Iowa has seen this warm of weather. The featured chart displays the year of the previous date that had temperatures as warm as those reported by the automated sensors. The plus symbol means the previous date was during this year. For some locations, this was the warmest temperature in over 10 years! For the IEM computed statewide average, yesterday was the warmest day since 1 August 2006 and the warmest day in June since 1988. > NWS Watch/Warning Summary for 07 Jun 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 139 0 | 0 0 0 0 0 | 2 Fl Flood 27 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: 140 Verified: 82 [58.6 %] Reduction of Size Versus County Based [68.5 %] Average Perimeter Ratio [17.0 %] Percentage of Warned Area Verified (15km) [21.1 %] Average Storm Based Warning Size [1599 sq km] Probability of Detection(higher is better)[0.85] False Alarm Ratio (lower is better) [0.41] Critical Success Index (higher is better) [0.53] -------------- next part -------------- An HTML attachment was scrubbed...

These events consist of a rapid rise in temperature along with a drop in dew point. The featured chart displays the one minute interval observations from the airport sensor showing perhaps two heat burst signatures. A rise in temperature to over 100 degrees can be seen along with a drop in dew point to near 30. The physical reason for these events remains somewhat a mystery, but they are almost always found near an area of rapidly decaying rain showers. > NWS Watch/Warning Summary for 10 Jun 2011 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 11 0 | 0 0 0 0 0 | 0 Svr Tstorm 251 1 | 0 3 1 0 0 | 5 Fl Flood 20 2 | 0 1 1 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: 265 Verified: 128 [48.3 %] Reduction of Size Versus County Based [65.3 %] Average Perimeter Ratio [26.4 %] Percentage of Warned Area Verified (15km) [21.0 %] Average Storm Based Warning Size [1248 sq km] Probability of Detection(higher is better)[0.81] False Alarm Ratio (lower is better) [0.52] Critical Success Index (higher is better) [0.43] -------------- next part -------------- An HTML attachment was scrubbed...

The quality controlled Iowa COOP data for October 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:

October 2010 temperatures averaged 53.9 degrees or 3.0 degrees above normal while precipitation totaled 0.98 inches or 1.54 inches below normal. This ranks as the 41st warmest and 16th driest October among 138 years of records.

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

The featured chart presents the running maximum daily number of hits made against the website. The past ten years have been quite the experience as the website has built up massive archives of data and exposed this data via various web services. The most rewarding part of the IEM has been the close interactions with those in the private sector and other government agencies that have made the IEM possible. The work will continue as there are still more datasets to pull in and improvements to be made to the entire system. > NWS Watch/Warning Summary for 17 Jun 2011 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 11 0 | 0 0 0 1 0 | 2 Svr Tstorm 208 1 | 0 0 1 8 0 | 6 Fl Flood 11 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: 220 Verified: 98 [44.5 %] Reduction of Size Versus County Based [70.0 %] Average Perimeter Ratio [22.2 %] Percentage of Warned Area Verified (15km) [19.5 %] Average Storm Based Warning Size [1373 sq km] Probability of Detection(higher is better)[0.81] False Alarm Ratio (lower is better) [0.55] Critical Success Index (higher is better) [0.40] -------------- next part -------------- An HTML attachment was scrubbed...

The IEM has been providing GeoTIFFs of satellite data for a few years now. This data was basically a re-packaging of a product provided by NOAA. This product was somewhat delayed and only updated twice an hour (the baseline for GOES data). When the satellites are in rapid scan operation, the more frequent data was not available.

I have now written a decoder for the raw satellite information that comes in near real-time from NOAA. The decoder converts the imagery into GIS-ready rasters. You can download the raw files here . The files are also being archived in the standard location on the IEM h ere. The files are in a lambert conic comformal projection with reference latitude of 25 north and reference longitude of 95 west.

The IEM tilecache service is also aware of these rasters and you can find more details on these services here.

Enjoy!

The featured chart is of the past seven days for Childress, Texas showing temperatures above 100 degrees each day. Iowa has not seen weather like that for many years and from the looks of the forecast, it will continue to be that way.

This was thanks to a thick cloud cover and cold air brought in from our north. The featured chart looks at a measure of the amount of cloud cover on days were the high temperature was at record minimums and maximums. It makes intuitive sense that the coldest days are typically more cloudy during the spring, summer, and fall months as the sun is effective at warming the ground thanks to its high declination. Clouds are less important in the winter months as temperatures are dominated by organized air masses and the sun is less effective. For the warmest temperatures, having more sunny conditions are the most important in October it appears. Outside of a blip for warmest days in May, the plot has two clear annual signals! > NWS Watch/Warning Summary for 23 Jun 2011 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 10 0 | 0 0 0 0 0 | 1 Svr Tstorm 123 0 | 0 0 0 0 0 | 2 Fl Flood 15 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: 133 Verified: 71 [53.4 %] Reduction of Size Versus County Based [71.7 %] Average Perimeter Ratio [14.7 %] Percentage of Warned Area Verified (15km) [20.2 %] Average Storm Based Warning Size [1876 sq km] Probability of Detection(higher is better)[0.86] False Alarm Ratio (lower is better) [0.47] Critical Success Index (higher is better) [0.49] -------------- next part -------------- An HTML attachment was scrubbed...

The featured chart compares the number of days above the 75th percentile with the number below the 25th for each June back to 1893. An average year would see around 15 days per month within these two intervals. Interestingly, it is much more rare to see many days in a month below the 25th. This is because the cold patterns tend to be more transient than the hot and dry patterns that can be reinforced by ample sunshine and dry conditions. > NWS Watch/Warning Summary for 24 Jun 2011 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 1 0 | 0 0 0 0 0 | 0 Svr Tstorm 189 0 | 0 0 0 0 0 | 5 Fl Flood 11 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: 189 Verified: 92 [48.7 %] Reduction of Size Versus County Based [70.3 %] Average Perimeter Ratio [20.8 %] Percentage of Warned Area Verified (15km) [15.0 %] Average Storm Based Warning Size [2155 sq km] Probability of Detection(higher is better)[0.81] False Alarm Ratio (lower is better) [0.51] Critical Success Index (higher is better) [0.44] -------------- next part -------------- An HTML attachment was scrubbed...
