Get used to this.

The thing about summer is that patterns get slow and sluggish, less dynamic. A cold front has sagged into the middle of the Ohio Valley and is connected with a stationary front through Montana. Not strong, not moving much, but present, which will mean isolated storms within a couple hundred miles o the boundary. Not strong, but not moving, either.

Expect August to be dominated by two different stories. The continuing heat, which has lead to extreme warmth in the north Atlantic, and the approach of peak hurricane season. All other things being equal, you might expect that the increased sea surface temperature would lead to an increased risk for hurricane development. There is a long way to go and it certainly remains to be seen, but at this point, it’s still pretty quiet out there.

Of course, while it feels like a slow season, the next named storm will already be the 5th of the year.

There is a bit of cooler air filtering into the northern US, slowly but surely. Bands of training thunderstorms are expected in the Upper Midwest today. The threat for storms is in the hail and wind variety, particularly when they get going later today. The jet is lingering near the Canadian border, so don’t expect this action to move further south. Sure, it’s hot down there, but at least it isn’t stormy, right?

Strong storms coming for Michigan tomorrow

There is some heavy weather in the northern Plains this evening, including tornado warnings in South Dakota and Nebraska. Fortunately, this activity is in pretty remote terrain, which makes tomorrows threat more dangerous, even if the storms were at the same level as today’s, because Michigan, especially lower Michigan, is well populated.

Tornadoes and strong winds will be the primary concern, though hail is a threat as well.

I’m looking a little bit at the Harrisonburg forecast…

I’m looking a little bit at the Harrisonburg forecast from a few days ago, and I am reminded that, because of the combination of high population and density of vegetation, the region is very sensitive to wind storms. While in the Plains or Midwest, you see long track lines of severe weather with the heaviest storms, you get mottled spasms of wind reports out east like they did over the weekend in the Atlantic Coastal Plains.
