Omaha Storm Weather question

[Cup of Cheese]

I have an odd question about Omaha storm weather and wind questions. From my rather poor memory, it seemed like a majority of the storms came from southwest. In other words, winds were blowing from the southwest to northeast, and the storms approached from the southwest.

Is that in any way accurate?

That's not at all inaccurate. Often, the classic storm events you expect do "come up the pike", meaning they generally come up along I-80, so Southwest. But in recent years, a lot of the big events have been coming from the North/Northwest, which is a departure from what I remember growing up, but of course, its not a log of sorts. It just seemed like most of the time, the big, bad storms came from the Southwest.

The big events that happened this year came from the Northwest and the Southwest, respectively.

Then we hadn't had any sort of memorable event since 2017, when the hailstorm came from the North. The Bellevue Tornadoes that year also came from the Northwest.

Then the West Omaha tornado in April of 2016 came from the Southeast, which was really different.

The Mothers day Tornado of 2014 was a classic, mean as heck, "up the pike" storm.

Whenever that huge hailstorm that hit Blair was, came from the Northwest.

Prior to that, all the other big storms I remember came from the Southwest, but I don't have a log of all of them.

I feel like the early season storms and more isolated cells generally come southwest to north east. However I feel like the later season storms, lines of storms, and overnight storms more often come from the northwest to southeast. I could be completely working, but that just the way I remember it.

The big supercell storms need lots of energy to get that mesocyclone turning. This usually means coming from a southerly origin where the warm gulf air impacts on polar air still retreating north. Thus the spring storms come from the southwest. By the late summer, the intersection of warm gulf air and cold polar air is over the Dakotas and not as intense.

Later in the season, some of this could power storms from the north and as more of the storms mentioned are really not mesocyclone based, but rather frontal boundaries, less directional bias is seen as you aren’t dependent on the massive energy of the gulf/polar boundary.
