Farewell Jefferson Webcam

04 May 2017 05:25 AM
The saying is that you'll never forget your first and within the context of IEM archived webcam imagery, the KCCI-TV webcam in Jefferson was it. Back in 2003 an unique partnership was forged for the IEM to maintain an archive of the webcam imagery and about 1.5 million images later, the running archive for the site will come to an end. This webcam was replaced by an alternative solution. This location has been the most reliable in the network and provided some of the best lapses captured over the years. Cheers!

Pretty Convection

07 Jul 2016 04:27 AM
A few thunderstorms were able to fire late Wednesday afternoon and made for very picturesque viewing with mostly clear skies surrounding them. The featured picture is from the webcam in Parkersburg showing pretty anvil near sunset. These storms died off quickly after sunset as they little wind shear support. The organized and strong storms arrived in the state overnight again bringing damaging winds.

Ames Landspout

17 Jul 2015 05:47 AM
The featured picture was captured by the webcam on the ISU Ag Farm just south and west of Ames on Thursday. This landspout was reported to have briefly touched down, but no damage has been found at the time of this writing. This storm prompted a tornado warning for Ames that lead many to discover that Ames has talking sirens now! These landspouts are formed when a strong updraft stretches an area of spin into a smaller area, which increases the rate of spin. Check out the recent news item with a link to the YouTube lapse of this event.

10 years of webcam imagery

23 Jul 2013 05:30 AM
Yesterday marked the 10th year of webcam imagery collection by the IEM. This is thanks to our partners (KCCI-TV, KCRG-TV, KELO-TV, and the Iowa Department of Transportation) who allow us to collect and archive images from their respective networks. The featured chart shows the number of images saved per year along with the first image collected from the KCCI-TV webcam in Jefferson back in 2003. These images are valuable environmental data providing easily discernible visual reports of sky and ground conditions. Along the way, over 300 lapses have been uploaded to YouTube, including a very popular Gravity Wave video with over 1.3 million views!

Ames webcam used for sunsets (often facing west) and Nevada webcam used for sunrises (often facing east)

Red Sky

12 Jul 2013 05:00 AM
Most are familiar with the old adage; "Red sky at night, sailor's delight. Red sky at morning, sailor take warning." Does this saying apply for us land-locked Iowans? IEM's webcam archive contains an image every five minutes dating back to as far as 2003. For the featured analysis, webcam images approximately 10 minutes prior to sunrise and 10 minutes after sunset were analyzed for amount of red in the sky. The algorithm attempted to differentiate red sky from the red horizon that is common with everyday sun rises and sets. Of 2300 some sunrises and sunsets, 248 red sunrises and 88 red sunsets were identified by an algorithm. For these events, hourly precipitation data from Ames was queried to see if measurable precipitation fell in the 24 hours proceeding the event. The third bar is daily climatology which shows not much of a signal with these events, but there is a slight increase for red sky at morning events. Obviously, a limited sample and computer program does not prove or disprove this adage.

No snow cover this year

09 Feb 2012 05:57 AM
The featured image is a composite of webcam images from Jefferson Iowa for the past nine years. The reported snow depth is shown for each year. There has been very little snowfall to speak of for many places in the state this winter as compared with recent years. A chance of snowfall is expected this weekend, but temperatures are expected to warm again to above freezing to help melt it away.

5 straight sunrises

02 Jul 2010 06:24 AM
This week has been a remarkable for having mostly clear skies and high temperatures around 80, nearly perfect for summer! The featured image shows that the sunrise has been visible each day this work week and our streak may continue Saturday morning. All good things come to an end though with humidity returning this weekend along with thunderstorms on Sunday.

Sunny at noon?

20 Nov 2009 06:08 AM
It seems like we have been stuck with cloudy days for a while now. The featured image attempts to illustrate this by taking a sample of the Ames webcamera imagery at noon each day since the first of August. Clear skies stick out nicely as compared with dreary gray images. The forecast has some hope for seeing some sun this weekend with mild temperataures in the 50s.

Longer daylight hours

17 Feb 2009 06:19 AM
The featured image is from the Glidden webcamera at 4:20 PM for three days since the start of winter showing the sun getting higher in the sky. If you were to make a composite image of the sun's location in the sky over the course of a year, you would get a figure 8 shaped analemma. The IEM generated a cheap timelapse from the Glidden cam showing a portion of this pattern.

Nevada webcam on 19 Dec 2007

Careful of the Fog

20 Dec 2007 07:17 AM
Dense fog has developed most every day this week as warmer air from the south keeps encountering all of this cold ice and snowpack covering Iowa. On Wednesday, the webcams caught some neat lapses of the fog lifting and then settling in again. The Nevada webcam lapse is from 150 feet above the ground, so it was above the shallow layer of fog that crept along Wednesday morning. The Newton webcam lapse shows thick forming, lifting, settling back in, and then lifting once more. We will see more dense fog today in some locations.

Bore-ing

04 Oct 2007 06:38 AM
So much happened on Tuesday that it is filling two days worth of features! This webcam image was taken from the Saylorville Lake webcam on Tuesday morning, you can see clearing on both sides of the cloud that is moving to the east. This feature is showing the wave motion in the atmosphere with downward motion (trough) in the clear area and upward motion (crest) where the cloud is. The experts are still looking at the data from this event, but early indications are that it was a bore! You can view webcam lapses from Tama, Indianola, and Saylorville Lake.

Sunrise shots from Madrid webcam

The moving water tower or...

06 Sep 2007 02:55 AM
The featured image is of the sunrise for 3 dates this year from the Madrid webcamera. Any ideas why the sun's position relative to the water tower (indicated by red arrow) changes? Is the sun moving relative to the Earth? Is the water tower moving? Of course, the answer is related to the changing of the seasons as the tilt of the Northern Hemisphere is slowly starting to point away from the Sun and thus the sun is more southerly in our sky. The effect can be illustrated by comparing webcam shots of the sunrise against a stationary object (water tower). The camera is looking east, so the sun is appearing further to the right in the image (to the south) as the days go by since late June. You can also notice the change in sunrise time as our days get shorter.

ISU Ag Farm webcam

Not Hallmark quality

08 Dec 2006 11:04 AM
The cold weather certainly reminds us of winter, but wouldn't it be nice to have a nice blanket of white snow out there to cover up the ugly shades of brown evident from the webcameras. The forecast for the next 7 days doesn't hold much hope either.

10 Nov 2006 06:25 AM
It was only two days ago temperatures climbed to record levels near 80 degrees. The weather on Friday will quickly remind us what time of year it actually is. The webcam in Algona is showing the collection of frozen water known as snow accumulating on the streets. Snow will fall at heavy rates at times today with totals approaching 6 inches or more in some lucky locations.

Dense fog impacted some parts of the state Tuesday morning. The featured image shows temperatures and dew points yesterday morning along with 3 webcam shots. You can see at 8 and 10 AM how the relative humidity was 100% with the fog present. At 11 AM, you can see the clear skies and the temperature has warmed above the dew point. The sun burns off the fog by mixing down drier air and warming temperatures above the dew point.

The famous Goodyear Blimp is gracing us with its presence this week in Jefferson to celebrate the 40th anniversary of a local tire dealer. The web camera in Jefferson has been closely watching the blimp. The camera is zoomed in about as far as it can go, so the image is somewhat blurry.

Indianola webcam at 7:06 PM on 24 Sep 2006

Setting nearly due west

25 Sep 2006 07:00 AM
Fall officially began this past weekend with the fall equinox. Besides the approximate 12 hours of daytime, the sun sets nearly due west for most every point on earth. The featured image is from the Indianola webcam auto tracking the sunset on Sunday. A due west sunset would be 270 degrees of azimuth (Az). This time of year is dangerous for drivers as the sun at sunset and sunrise will be directly in line of sight for east-west roads.

Days are getting longer!

A simple comparison of recent webcam images valid at the same time of day indicates what our bodies are already feeling, the days are slowly getting longer!

It seems that the past few winters we have had to wait until January to get our first major snowfall of the season. This winter we don't have to be patient! These snowfalls are the fun ones since shoveling is still a novelty and there is plenty of places to put the snow. Hello winter!

Where did the white stuff come from?

16 Nov 2005 07:13 AM
Ah yes, it is November. A powerful storm system is moving away from Iowa this morning and our winds will finally begin to die down some. Snowfall totals were not very impressive, but the wind continues to blow the snow around making road plowing difficult. Temperatures will remain below freezing until this weekend when our next storm system arrives.

Looking WNW from Agronomy at 12:30 PM on 8 Sep 2005

Direct Hit

09 Sep 2005 07:21 AM
Thursday was a wild day for weather on the ISU Campus. A weak tornado touched down on campus and produced a narrow path of extensive tree damage. The Agronomy Building, which houses the IEM, took a direct hit. The featured image is a shot from the webcamera sitting ontop of the Agronomy Building just before it hit. Unfortunately, the big-foot image quality may tend to discredit its veracity, but the dark cloud in the middle matches up very well with the damage path and time of the tornado. Meteorology undergrad Scott Lincoln put together an excellent page detailing the damage.

Proof that the Earth is round

16 Jun 2005 06:53 AM
Via the magic of digital photography, the featured image today proves that the Earth is round! The image is a composite of four webcamera shots synced in time from last evening (click the image for more details). You can see that it is much darker at Lake Rathbun (upper left panel) than it is further west and north at Rockwell City (lower right panel). If the earth was flat, you would expect to see a sunset at the same time. Now, to prove that the Earth is a sphere and not a cylinder, here is a mpeg movie lapse of the sun setting. The movie clearly shows the slanted path of the sun relative to the horizon. What a discovery!

Ames webcam from Thursday evening

Fiery Sky

27 May 2005 08:00 AM
The ISU webcam caught a glimpse of the spectacular light show Thursday evening. While the thunderstorms were not that strong, the air near the ground was rather dry. So when rainwater from these storms fell into this dry layer, it quickly evaporated and cooled the surrounding air. This cooled air then rushed to the ground producing brief gusty winds which then pick up dust to produce the ground dust storm. All of the red in the sky is a result of the Rayleigh scatters (dust and raindrops) scattering the blue light away.

We are loosing our colors! It is getting to be that ugly time of year where the colorful leaves are off the trees and everything is a shade of brown. Some locations in Iowa are at peak color while most are past that point. If you haven't already, this weekend is probably the last to see the fall foilage.

Jefferson webcam for 25 Aug 2003 and 2004.

Staying green

25 Aug 2004 08:26 AM
The picture showns the difference between last 25 August and this year in Jefferson. You can see how much greener the vegetation is this year than last. The reason being the cool and rainy August weather that is favorable for keeping the plants green. Normally, August is hot and dry which usually causes the grass to go dormant.

2004 has been the year of the landspout/F0/ropenado/whatever you want to call it. The Jefferson webcam may have caught a glimpse of one Sunday afternoon. These pictures taken by the public near Gowrie are much more conclusive. The low level environment this year has been very conducive for the formation of these small tornadoes.
