Posted on30. Oct, 2011 by Jesse.
Late yesterday afternoon we first mentioned a potentially high impact storm system that may affect large parts of the US next weekend. While this is a system that needs to be closely monitored, as it is poised to potentially be the first major high impact surface cyclone of the fall season, it is far too [...]

Convective Addiction members will be monitoring today as each of the home states for our entire team is under the scope for a conditional threat of severe weather again today, with the main peril likely being damaging winds.

June 14, 2011: New Boston, MO Tornado
Posted on15. Jun, 2011 by Jesse.
A spectacular view of a tornado in northeastern Missouri at night is a rare treat, and getting a decent viewing angle is even less likely. Frankly, I was convinced that this particular severe weather event would be mostly a non-event due to the presence of a strong EML (warm layer aloft that prevents vigorous convective [...]

Posted on25. May, 2011 by Jesse.
Another significant severe weather day appears in store for parts of the Midwest and Corn Belt regions, especially over parts of the Middle Mississippi and Ohio River valleys. As yesterday’s system treks eastward, the strong mid and upper-level dynamics will once again coalesce with a very unstable warm sector to potentially yield an outbreak of [...]

All of the synoptic ingredients appear to be coalescing today for a major severe weather outbreak across the Central and Southern Plains, and the SPC has already outlined a high risk for severe weather across the region. Some details remain to evolve, so mesoscale forecasting will be important this afternoon as the event gets closer [...]

I chased on Friday, April 22, 2011 with Dr. Tom Williams from Western Illinois University, along with fellow chasers Jeremy Degenhart and Eric Apel. We witnessed several tornadoes and tornadic circulations in the St. Louis region, including power flashes associated with the cell that moved through Pontoon Beach, IL after dark. We initially targeted Kingdom [...]

A significant severe weather event appears poised to unfold across a large part of the nation’s midsection tomorrow, especially across areas of the Upper Mississippi River and Ohio River valleys. The current surface analysis shows a stationary boundary draped largely proximal to the I-70 corridor, with a 997 mb surface cyclone situated over the Southern [...]

Posted on11. Apr, 2011 by Jesse.
I chased this day with Brad Goddard and Jodi Irvin; we initially targeted Council Bluffs, IA as a preliminary starting spot, but decided to move north to the Missouri Valley truck stop exit when a cumulus field started to build northwest of Omaha between 4 PM and 5 PM. A healthy storm popped up west [...]

A significant severe weather outbreak appears poised to take aim on the Upper Mississippi Valley/Superior Uplands region of the Upper Midwest on Sunday afternoon into the evening hours. This potentially significant SVR weather event could feature all modes of SVR weather, including large hail, damaging winds, and strong tornadoes from long-lived, discrete supercells. A potent [...]

FCST: 04/09/11 – Midwest / Mid-Mississippi Valley
Posted on08. Apr, 2011 by Jesse.
Saturday is looking to be sort of the archetypal “day before the day” severe weather event in the central CONUS. A powerful upper-level trough currently situated over the Great Basin/Sonora region of the SW CONUS will continue digging eastward as it completes amplification within the longwave regime, taking aim on the Upper Midwest by the [...]
