Severe Weather In The Midwest This Wednesday

11/9/15

A strong frontal system will plow through the middle part of the United States on Wednesday bringing a widespread threat for severe weather across America’s heartland. As of today’s forecasts, here is how the set up is looking for Wednesday.

Wed Set Up Day

Several different ingredients for severe weather will be coming together including a strong cold front and VERY active jet stream helping to stir trouble here on the ground. One thing to notice on the above graphic is that this system will have limited moisture (dew-points) to work with. This is typical for this time of year the further north you are but it doesn’t completely rule out the chance for severe weather, even though typically the more moist the air is the better the overall threat for storms.

Here is the current outlook from the National Weather Service for Wednesday’s potential storms.

Notice how the set up graphic above correlates with the outlook. The area where the strong jet stream winds, cold front, low pressure and moisture coincide is where the best chance for storms including isolated tornadoes will be Wednesday afternoon and evening.

All of this activity will head our way Wednesday night with the chance for strong storms here in West Central Ohio. The good news for us is that several factors will work against us getting any severe weather. Here is a look at the potential set up by about midnight on Wednesday night.

We’ll still be dealing with a strong jet stream moving in, so that greatly enhances our chance for strong winds to the tune of 40 to 50 mph. But we won’t have barely any moisture to work with and without higher dew points the atmosphere has trouble becoming unstable, and without that instability storms have a hard time developing and maintaining strength. Here is a look at our projected dew points Wednesday night. Notice the higher dew points staying to the south and west of West Central Ohio. Where you find the higher moisture, that’s where you’ll find the better chance for storms Wednesday night.

Looking closer at the severe weather outlook, it’s clear that’s where the better chance for severe weather is as well.

Having said that, a very strong jet stream can sometimes make up for a lack of instability, but the fact that all this is trying to come together at night has me pretty confident that we’ll very likely just deal with the chance for gusty winds into Thursday morning.

This is definitely something worth watching over the next day or so, but as I mentioned above, I’m not too concerned as of now. Stay tuned!
