Screenshot from a video showing a large tornado in North Dakota Sunday. The state was hit by as many as 19 twisters yesterday. |
We had the tornadoes in Utah Saturday, which I've already mentioned in this here blog thingy. I've got an update on that below, but first, more odd tornadoes, this time in North Dakota.
During Sunday afternoon, a total of 22 reports of tornadoes came in, all but three of them mostly along a narrow north-south line in central parts of the state. The actual number of tornadoes will be determined by the National Weather Service.
Observers said this was probably the biggest September North Dakota tornado outbreak on record.
The tornadoes hit sparsely populated areas, though there was damage in the tiny central North Dakota communities of Denhoff and Cannon Ball.
The situation kept meteorologists exceptionally busy, as tornado warnings blared across central North Dakota most of the afternoon and evening. At one point, storm chaser Brian Copic had two tornadoes in his sights: A large, wedged shaped twister and a skinnier one nearby.
North Dakota does get tornadoes, averaging about 29 of them per year. But we're generally past the season for twisters there. But Sunday was an exception.
The direction of Sunday's storms was a little off, too. They headed north to northwest, not in an east or northeast that most tornadic storms travel.
North Dakota is also not known for its heavy rain especially in the autumn. It's in the middle of North America. Humid Gulf of Mexico or Pacific Ocean air has a lot of trouble making it that far north by September, so rainfall is usually fairly sparse.
However, Bismarck, North Dakota got more rain in an hour Sunday than they normally do in the entire month of September. Just under two inches came within that hour, compared to the 1.72 inches that usually falls all month. The storm total in Bismarck Sunday was 2.44 inches.
Not surprisingly, the city and points south were hit by widespread flash flooding.
It's been a rough year for severe weather in North Dakota, even by their standards. Four tornadoes and 100 mph straight line winds hit areas near Grand Forks about a month ago. North Dakota also just approved for disaster assistance from damage caused by tornadoes, high winds and flooding back on June 20-21.
In Utah, two homes, two houses trailers, a hay barn and fifth-wheel trailer were destroyed in the tornado. Nobody was hurt, but several pets are missing. Two additional houses were damaged and power lines have come down.
With Sunday's outbreak, it looks like North Dakota will have had about 60 tornadoes this year, the most there in a single year.
VERMONT LEFT OUT
Here in Vermont, we often get the remnants of any big storms to our west. Usually in the form of some autumn rain. We could really use it, but, again, not this time. The drought stays strong.
The Plains storm is lifting directly north into Canada and dissipating. It won't give us any rain at all. Instead, the forecast is the same as it was yesterday: It will be warm and dry through Thursday. Then, a rainless cold front will hit Friday and it will turn cool and dry. Then it will probably warm up again.
Our next chance of rain isn't until September 25 or 26, but even that is highly uncertain. That storm might go by to our south, missing us again.
We don't want tornadoes here, but it would be nice if one of those tornadic systems spun off a little rain our way.
