April 25, 2015 – Illinois

Nick Nolte / Blog, Storm Chasing / / 0 Comments

April 25th was the second day of a little mini chase weekend and a shortwave trough was moving east into the Ohio Valley while it deamplified a bit. That was coupled with the nose of a 130kt jet streak at 250mb and a sub-1000mb surface low that was progged to drift east throughout the day. The plan was to play in Southern Illinois just east of St. Louis where a clear slot was expected to form allowing for modest instability to develop and hope for storms to develop and ride the front.

April 24, 2015 – Kansas

Nick Nolte / Blog, Storm Chasing / / 0 Comments

April 24th and 25th presented a couple of opportunities for severe weather across the Great Plains and lower Ohio Valley, so I left Michigan on the 23rd and overnighted in Cameron, MO. Cameron has become my goto town for sleeping if I’m heading out to chase the Plains and leave the evening before. Anyway, the 24th presented two targets for chasers. The first target area was Central Kansas where a surface low and slow moving warm front provided a focus for severe weather. The second was Eastern Texas where a warm front/outflow boundary was being intersected by a rapidly advancing dryline. Both areas were delineated in an enhanced risk from the Storm Prediction Center, although the Texas play had higher tornado probabilities.

Using QGIS to map your travels

Nick Nolte / Blog, Tutorials / / 0 Comments

I know some of us are familiar with the county tracking website where we log all the counties we’ve visited and generate a map of where we’ve been. I even have my own map there, but I haven’t updated it in a couple of years. The user input on that website relies on you manually clicking on whichever counties you want to log as visited. Many of us like statistics, and we like to track where we’ve been. As a GIS Analyst, I love maps. I love mapping data and analyzing that data on maps as well. I thought I could do a post (or a series of posts) on using GIS to generate maps from our storm chasing shenanigans.

April 9, 2015 – Iowa / Illinois

Nick Nolte / Blog, Storm Chasing / / 0 Comments

The day began in Cameron, Missouri and our preliminary forecast was looking at the eastern portion of Iowa for supercells early on in the afternoon. A low pressure that was centered over eastern Nebraska was progged to move eastward dragging a trailing cold front along with it. To the east of the surface low a warm front across Iowa and northern Illinois was the focus of our chase for the day and we expected to play just east of the triple point.

April 8, 2015 – Southwest Kansas

Nick Nolte / Blog, Storm Chasing / / 0 Comments

April 8th and 9th had been shaping up to be decent severe weather days and the chatter amongst chasers had grown to a fever pitch as the first big system of the spring seemed poised to kick the season off. A trough centered over the southwest was beginning to eject into the Plains and bringing with it the dynamics we would need to kick off severe weather. At the surface, a surface low was forecast to strengthen in southwest Kansas before it moved off to the northeast and eventually into Wisconsin by the following day. A couple target areas presented itself for Wednesday: the triple point and east along the warm front along the Kansas/Oklahoma border and further south along the dryline into the Texas Panhandle.
