The IEM database server just got a big hardware and software upgrade. It will take me a bit to straighten out a few datasets, but otherwise things should be good to go. Please let me know of any applications you see problems with. A couple of database syncs are still processing, so the known errors should stop around 2 AM or so.

This upgrade puts the IEM at PostgreSQL 8.4 and PostGIS 1.4. > Yesterday's Daily Feature +---------------------------------------------- http://mesonet.agron.iastate.edu/onsite/features/cat.php?day=2009-07-31 | Title : Average Temperature | Date : 31 Jul 06:06 AM | Votes : Good: 22 Bad: 3 +---------------------------------------------- Today's feature is a bit of a thought provoker for you to consider. July's average temperature is expected to be the coldest on record for Iowa, but what is an "average temperature"? Setting aside the spatial aspects, typically this value is the simple average of the daily high and low temperature (since that observation is the most commonly available for the longest periods). Since automated sensors report information every hour, how does a simple average of these values compare with the average of the high and low daily temperature? The featured chart presents the monthly mean biases based on observations from the Des Moines Airport site back to 1973. The positive values mean the simple average of high and low temperature yields a warmer value than the average of the hourly observations. The red bar represents the 95% confidence level for the mean. There is a clear annual signal in this chart, what causes it? > NWS Watch/Warning Summary *** Products issued on 31 Jul 2009 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 5 0 | 0 0 0 0 0 | 0 Svr Tstorm 133 0 | 0 0 0 2 6 | 4 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 From mesonet at mesonet.agron.iastate.edu Sun Aug 2 11:01:03 2009 From: mesonet at mesonet.agron.iastate.edu (mesonet at mesonet.agron.iastate.edu) Date: Sun, 2 Aug 2009 11:01:03 -0500 Subject: IEM Daily Bulletin Message-ID: <200908021601.n72G13Uc016951@iem10.local> Iowa Environmental Mesonet Daily Bulletin Data valid for 01 August 2009 > News No news is good news > Yesterday's Daily Feature No feature posted. > NWS Watch/Warning Summary *** Products issued on 01 Aug 2009 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 1 0 | 0 0 0 0 0 | 0 Svr Tstorm 28 0 | 0 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 From mesonet at mesonet.agron.iastate.edu Mon Aug 3 11:01:03 2009 From: mesonet at mesonet.agron.iastate.edu (mesonet at mesonet.agron.iastate.edu) Date: Mon, 3 Aug 2009 11:01:03 -0500 Subject: IEM Daily Bulletin Message-ID: <200908031601.n73G13Cp003984@iem10.local> Iowa Environmental Mesonet Daily Bulletin Data valid for 02 August 2009 > News No news is good news > Yesterday's Daily Feature No feature posted. > NWS Watch/Warning Summary *** Products issued on 02 Aug 2009 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 8 0 | 0 0 0 0 0 | 0 Svr Tstorm 95 5 | 0 0 0 1 14 | 4 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 From mesonet at mesonet.agron.iastate.edu Tue Aug 4 11:01:04 2009 From: mesonet at mesonet.agron.iastate.edu (mesonet at mesonet.agron.iastate.edu) Date: Tue, 4 Aug 2009 11:01:04 -0500 Subject: IEM Daily Bulletin Message-ID: <200908041601.n74G145x032214@iem10.local> Iowa Environmental Mesonet Daily Bulletin Data valid for 03 August 2009 > News No news is good news > Yesterday's Daily Feature +---------------------------------------------- http://mesonet.agron.iastate.edu/onsite/features/cat.php?day=2009-08-03 | Title : Diurnal Cycle | Date : 03 Aug 06:05 AM | Votes : Good: 16 Bad: 4 +---------------------------------------------- On Friday, the featured plot shown two seasonal maxima of difference between the daily average computed by taking the high and low temperature to that of taken by averaging hourly observations.

The quality controlled COOP data for March 2009 has been uploaded to the IEM. The climodat reports have been subsequently updated as well. Harry Hillaker, our state climatologist, passes along these notes for the month:

The statewide average temperature was 36.7 degrees or 0.7 degrees above normal. Precipitation averaged 3.11 inches or 0.90 inches above normal while snowfall averaged 1.4 inches or 3.4 inches less than usual. This ranks as the 51st warmest and 19th wettest March among 137 years of records. Snowfall was the 15th lowest among 122 years of records for March. The last March with less snow was in 1997.

New daily records set for the month:

The featured map is an estimate of the total rainfall for the past 7 days. Select locations in the Cedar Rapids and Iowa City area have seen upwards of 8-10 inches causing flooding, but nothing like what was seen in 2008. The good news is that our weekend looks dry, but will be on the cool side of what to expect in late August. > NWS Watch/Warning Summary for 28 Aug 2009 Summary +_________ By WFO ____________+ Watches Type US IA | ARX DVN DMX OAX FSD | US Tornado 2 0 | 0 0 0 0 0 | 0 Svr Tstorm 17 0 | 0 0 0 0 0 | 0 Fl Flood 17 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: 19 Verified: 5 [26.3 %] Reduction of Size Versus County Based [56.6 %] Average Perimeter Ratio [46.5 %] Percentage of Warned Area Verified (15km) [16.5 %] Average Storm Based Warning Size [1084 sq km] Probability of Detection(higher is better)[0.82] False Alarm Ratio (lower is better) [0.74] Critical Success Index (higher is better) [0.25] -------------- next part -------------- An HTML attachment was scrubbed...
