The featured time series is from the RWIS site on US Highway 20 near Waterloo. The green line (dew point) tells the story of what happened to cause an icing event. Moist air was surging into the state on Saturday with air temperatures hovering just below freezing. Since the cold air was shallow and near saturation, rain was able to fall to the ground without much evaporation nor phase change and then immediately freeze as pavement temperatures were below freezing. The timing of this event late in the afternoon followed by a cold front passage both conspired to prevent most any melting over night. Cold temperatures on Sunday kept nearly all of this ice around on untreated surfaces. > NWS Watch/Warning Summary *** Products issued on 05 Jan 2009 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 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 Wed Jan 7 11:01:04 2009 From: mesonet at mesonet.agron.iastate.edu (Iowa Mesonet) Date: Wed Jan 7 11:01:08 2009 Subject: IEM Daily Bulletin Message-ID: <200901071701.n07H14RI004923@mesonet.agron.iastate.edu> Iowa Environmental Mesonet Daily Bulletin Data valid for 06 January 2009 > News +---------------------------------------------- | Title : New WeatherNet: Harrisburg, SD | Date : 07 Jan 09:48 AM | Author: Daryl Herzmann | URL : http://mesonet.agron.iastate.edu/schoolnet/current.phtml?tv=KELO +---------------------------------------------- A new KELO-TV WeatherNet station has come online today.

We are saving data for all of the sites available in the feed. This was primarily done to support some of the ISU Senior Thesis projects done each year on the MOS data. I suspect that others will find it useful as well, so it is now linked in on the website under 'Archive'. Currently, the archive is complete back to 3 December 2008, but it could be backfilled for a number of years based on raw text archives stored locally and at the NWS. If there is interest, I'll backfill it :) At this point, there are two applications available on the page including an interactive table viewer on how a MOS variable changes over time and with model iteration. There is also a simple CSV application that web developers may find of use.

Please note that these statements are not official. - Cedar Rapids broke the all-time record low temperature with an observation of -29. This breaks the previous record of -28 . Of course, the -29 also breaks the record for 15 Jan. The wind chill dropped to -52 degrees at 7:52 this morning, which is close to the coldest value of -55 on Jan 20 1985. This is based on data the IEM has back to 1973 or so. - Dubuque set a record low for 15 Jan of -26, breaking the previous record of -25. Davenport NWS noted that these records may be in danger of being broke this evening at midnight before the day is done! - Sioux City hit a record low of -20, breaking the previous record for Jan 15 of -18. Overall, today was the coldest day in Iowa since 3 Feb 1996. Many locations in the state will struggle to get above zero. The last day with widespread highs below 0 was 4 Feb 2007. A number of locations are struggling to reach -10F, the last time this has happened was the same 3 Feb 1996. Minimum morning wind chills: Iowa City -43 Esterville -50 Dubuque -36 Cedar Rapids -52 Des Moines -38 Mason City -48 Waterloo -45 Spencer -48 Marshalltown -48 The wind chill at Des Moines was below -30F for 10 hours this morning. The last duration of this length happened back in 1997 and the last duration of even over 3 hours happened back in 1999. Looking at durations of extreme wind chills, the period up till 25 Dec 1983 was exceptionally cold. The wind chill at Waterloo was below -30F for 90 straight hours (~4 days!).

Here are some unofficial notes for the cold weather today (16 Jan 2009)... - The Ames airport dropped to at least -30F degrees with the COOP observer dropping to -33F. The ISU Ag Farm (which may or may not be the 'official') for Ames got to -22F. The previous record low for today was -22F. The last -30F reading from Ames Ag Farm was 14 Jan 1957. - Spencer hit a record low for today of -28F, the previous was -26F. - Burlington tied a record low of -18F. - Cedar Rapids broke their record low this morning with an observation of at least -27F. - Waterloo tied an all-time record low of -34 and easily broke the previous record low for today of -26F. - Mason City dropped to -31F, breaking the previous record of -25F. - Ottumwa broke their record low of -19F by dropping to -20F this morning. The Monticello AWOS station recorded a low temperature of -38F, which must be close to a record for an automated station in Iowa. Colder values reported in the state were probably from manual thermometers. I am still checking into this, so don't authoritatively quote me on it :) The Coggon NWS COOP observation this morning was of -40F, this is the first -40 reading in the state since 3 Feb 1996. > Yesterday's Daily Feature +---------------------------------------------- http://mesonet.agron.iastate.edu/onsite/features/cat.php?day=2009-01-16 | Title : 50-60 degree warm up gets us to just above freezing | Date : 16 Jan 06:26 AM | Votes : Good: 34 Bad: 7 +---------------------------------------------- Just another amazingly cold morning with low temperatures in the -40 to -20 degree range in Eastern Iowa. The featured plot of AWOS low temperatures shows a -38 in Monticello! Not shown, Waterloo tied its all-time record low temperature of -34.

The IEM generates this information by parsing the weather observations reported in METAR format. One of the complications of this data stream is that METARs routinely are reported in duplicate fashion with slight differences. Here is an example: For Waterloo, this METAR comes in the data stream: KALO 190054Z AUTO 33010KT 10SM OVC055 M03/M06 A2982 RMK AO2 SNE24 SLP109 P0000 T10331056 The T-group component gives precision necessary to convert this Celsius value (1033) into the Fahrenheit value recorded by the ASOS (26F). So the IEM database recorded 26... Then this duplicate METAR comes a few moments later: KALO 190054Z AUTO 33010KT 10SM OVC055 M03/M06 A2982 Since this observation does not have the T-group, the Celsius value (M03) converts to 26.6 or 27F! So the IEM database recorded 27 and displays 27, while the NWS product has 26 in the summary. Well, I wrote some logic to hopefully detect when this happens and not use the less precise temperature value when the T-group was present in a prior ob valid at the same time. Hopefully, I just did not introduce new bugs! > Yesterday's Daily Feature No feature posted. > NWS Watch/Warning Summary *** Products issued on 18 Jan 2009 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 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 Jan 20 11:01:07 2009 From: mesonet at mesonet.agron.iastate.edu (Iowa Mesonet) Date: Tue Jan 20 11:01:09 2009 Subject: IEM Daily Bulletin Message-ID: <200901201701.n0KH176C022606@mesonet.agron.iastate.edu> Iowa Environmental Mesonet Daily Bulletin Data valid for 19 January 2009 > News No news is good news > Yesterday's Daily Feature +---------------------------------------------- http://mesonet.agron.iastate.edu/onsite/features/cat.php?day=2009-01-19 | Title : 3+ days below zero | Date : 19 Jan 06:13 AM | Votes : Good: 20 Bad: 7 +---------------------------------------------- The featured time series from the Esterville Airport shows a period of 87 hours were the temperature never exceeded 0 degree F.

This is simply the depth of liquid water contained in the snow pack. Our lack of days above freezing has allowed the snowfalls to accumulate into a snow pack containing between 2-5 inches of water over the northern half of the state. The hope is for a slow snow melt so that the rivers have a chance to move water downstream. Some melting should occur this week as temperatures are expected to warm above freezing. > NWS Watch/Warning Summary *** Products issued on 20 Jan 2009 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 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 Thu Jan 22 11:01:07 2009 From: mesonet at mesonet.agron.iastate.edu (Iowa Mesonet) Date: Thu Jan 22 11:01:12 2009 Subject: IEM Daily Bulletin Message-ID: <200901221701.n0MH171M027047@mesonet.agron.iastate.edu> Iowa Environmental Mesonet Daily Bulletin Data valid for 21 January 2009 > News +---------------------------------------------- | Title : MOS Archive to 3 May 2007 | Date : 22 Jan 10:50 AM | Author: Daryl Herzmann | URL : http://mesonet.agron.iastate.edu/mos/ +---------------------------------------------- The IEM's archive of MOS (Model Output Statistics) has been backfilled to 3 May 2007.
