Days Six and Seven...

We're getting in late again tonight and after a little fiddling around with the models here tonight, I'm gonna leave a very short, abridged version of the past couple of days...

Thursday, we chased a high risk day in Nebraska... Had several supercells around us and even had a tornado form about 3/4 of a mile to our north southwest of Kearney. Pretty incredible!

Stayed the night in St. Joseph, MO - then chased southeastern Kansas on Friday. That didn't end up all that well, with scattered weak showers developing along the trailing front during the early-evening. No big storms developed until near sundown when the capping inversion finally broke down.

I'll write more tomorrow night or maybe Sunday, when I return home and have more time.

I'm too tired to write much...

More later...

Day two...

Had a fairly complex forecast this morning and really had several major decisions to make. First, if we wanted to buy into the risk further to our southwest in western Kansas or to take the more synoptically driven area of Minnesota into Wisconsin. Second, what computer model we wanted to take faith in (they were all really telling us three or four different things), and third, logistics, in general.

We had decided to drop my car, so that we could continue with only one vehicle. I didn't have a problem with it, so we needed to decide on our destination before finding out where to leave the car. If we were to go east-northeast, I was going to leave the car in Omaha with some friends of John's. If we were to go west, we were going to leave it in Salina or possibly Hays or Russell, KS.

The west option became the general consensus, and we targeted a Hays-Dodge City-Pratt area and while we got a little bit of a late start, we were still able to observe the blocky wall cloud when the Scott City, KS storm moved northeast into Rush County. We moved to near Bison, KS and observed this cell become outflow-dominate, much as the demise of nearly all the storms today. This did produce a brief gustnado to our south-southwest (about a quarter mile or so) for about 2-3 minutes and was able to get some photos and video of that. All kinds of chaser convergence along Hwy-4, and several of these falsely reported this thing as a tornado, when it obviously wasn't. I swear, some of these folks need to take their Skywarn training again. The YouTube video linked above was from someone actually sitting across the highway from us.

Anyhow, after this, we played around with other convection around southwestern KS, as an OFB from our convection pushed southward towards DDC. Air in this area wasn't worked-over quite yet, so we thought that this may have had the opportunity to fire off some decent Supercells yet. While other storms did develop, they never got their act together and after sitting near Great Bend for about a half-hour, we bagged the evening to retreat to our hotel in Russell. Our room was given away, unfortunately, and much to the displeasure of all of us, we had to relocate to another Super-8 in Hays. It isn't quite so bad, still, as logistics will still be quite simple from here tomorrow. So as far as the models stay consistent with what their progs were indicating earlier today.

A rather aggressive shortwave looks to eject out of Colorado tomorrow, affecting parts of southern Kansas and northern Oklahoma. So, we likely won't need to drive far. Dryline action could also be an option, and if worse comes to worse, upslope off the Colorado high country may also be a play for us.

We'll see things pan out tonight and tomorrow morning on the models and if any residual boundaries from tonight's convection will affect the environment around us.

I'll have photos and video up and available upon my return to GFK, but in the meantime, stay tuned... Six, possibly seven more days of chasing are left on this guy's vacation!

Early-Season Oubreak

As you can see, yesterday saw one of the largest severe weather outbreaks we have seen in some time. Over 50 reported tornadoes traversed through the Lower and Mid-Mississippi Valley yesterday and into last evening. And while this number will likely dwindle some as analysis may indicate redundant tornado tracks, I am sure it will still rank very high as one of the largest outbreaks ever for this early in the year. It, unfortunately, will rank as one of the deadliest 24-hour outbreaks this country has experienced in history. With over 50 fatalities confirmed thus far (26 alone, in Tennessee), it now exceeds the outbreak in Oklahoma of May 3rd, 1999.

The time of year and the late hour that many of these tornadoes hit are both contributing factors to the number of fatalities. But, also because these tornadoes hit largely populated areas. Tornadoes affected many large cities, including areas around Memphis and Nashville, Tennessee, as well as Fairview, Arkansas. Jackson, TN also was hit particularly hard, especially around Union University on the northwest side of the city. It is amazing no lives were lost here, as there were numerous students in dormitories at the time.

My thoughts and prayers go out to all of those that have been affected by this terrible outbreak.

A whole new definition

This certainly ranks right up there with the most counties I've ever seen included in one severe weather warning. It gives an all new definition to the term "blanket warning!" This is just crazy...

That's 25 counties whole or partially included in this warning! Granted, we're dealing with an intense squall line here. Also of particular note is the forward progression! Moving east at 80 mph!?! The line itself, isn't moving eastward quite that fast. I'm assuming the NWS caught the 80mph out of some SCIT information for an embedded cell in the echo wave pattern. Either way, seems like folks in Illinois and those back home in Indiana are dealing with some damaging winds this evening.

Soon enough, they'll find themselves at 10° or 20° F with snow falling... and winds at 30 mph! Pretty incredible system...

A sign of things to come?

Hopefully...!

We received our first SVR of the season this evening:

Unfortunately things moved through fairly quickly and while it was dark. No structure or anything would have been visible, even if I had made any attempt at taking a gander. I was at a friend's place visiting, when the warning came over the wire and didn't even know anything about it until after-the-fact. Interestingly, the city of Grand Forks decided to activate their sirens for the high winds associated with the storms. According to an SVS at 10:50pm, a gust of 57mph was recorded at the NWS office here in town. No lightning to speak of, so am still awaiting that proverbial "first clap" of thunder for the year...

Maybe this will be a preview of what is to come this convective season up here in the Northern Plains! We will see...
