Accuweather has an interesting post this morning, 4/19/11, from Alex Sosnowski, an expert senior meterologist, “Wild April Weather to be Followed by Wicked May.” Sosnowski sees no letup in the violent weather pattern that seems to have settled in over the central plains this spring.
He mentions that La Nina is weakening somewhat, but it is still very strong at present (a factor in Texas drought conditions), and he also talks about the jet stream, and a warmer than normal Gulf of Mexico (uh oh), contributing lots of warm, moist air, which collides with cooler, dryer air from the north. This situation, as we all know, can produce some very violent storms like the killer storms we saw last weekend.
One thing that he mentioned really caught my eye though he didn’t elaborate on it.
“Both of these secondary factors, combined with the strong jet stream may be cranking up the potential energy to be released in the form of violent storms.
It is possible that smoke from the wildfires may be limiting severe weather incidents (and tornadoes) over the favored area of southern High Plains.”
Well, I had a feeling that sooner or later, the smoke from the fires would become significant. Even with high winds dispersing it, there’s bound to be a lot of smoke. At least some experts think the smoke could be a determining factor in who gets violent storms and who doesn’t. Pretty amazing. Please read the full post. It’s short and to-the-point.
