Changes Coming???

Real Time Regional Radars:

———————————————————————————-

Today 6/2 – Scattered Thunderstorms – High 86° / Tonight – Isolated Thunderstorms – Low 70°

Today’s weather will remain much the same as yesterday’s weather, and the day before that, and the day before that, and the day before that, etc. Yep, we’re still stuck in that summertime pattern where we’ll see a daily chance of thunderstorms across the region.

A surface low pressure system will be located well north of the region on Monday. This will place us in the warm sector of the low pressure system, with the cold front located to our west. Although the result of this warm sector thunderstorm setup remains the same, the overall setup is different, which could lead to some changes in the forecast.

All in all, expect highs to be in the mid 80s across the region. As we saw on Sunday, those places that experience rain may cool back off into the 70s. As the sun sets, expect a decrease in thunderstorm activity. Lows will be in the upper 60s across the region.

Tuesday 6/3 – Scattered Thunderstorms – High 86° / Tue Night – Isolated Thunderstorms – Low 69°

On Tuesday, we’ll see a fairly robust low pressure system form to the west of the region. Severe weather looks very possible across the Plains. However, I don’t expect any severe weather in our neck of the woods. Thunderstorms will remain a possibility as we remain in the warm sector of the approaching storm system. This strong low pressure system could be the focus of change in the forecast. I believe we could all use some change, right?

What if the change was stronger storms?

Expect highs to be in the mid to upper 80s across the region. Per the usual, we should expect thunderstorms to diminish across the region as the sun sets. Lows will be in the upper 60s to low 70s across the region as well.

Wednesday 6/4 – Isolated Strong/Severe Thunderstorms – High 90° / Wed Night – Scattered Thunderstorms – Low 70°

On Wednesday, our forecast becomes a bit more interesting as well as challenging. The aforementioned strong low pressure system will continue to move eastward into the mid Mississippi Valley region, as well as into the Ohio Valley. This places us pretty close to the center of low pressure. This will help strengthen any storms that form.

As for now, I expect the main hazard to be heavy rain with any thunderstorms that form during the evening hours over the region. Precipitable Water values will be quite high. This is a good indication that our atmosphere is in a moist state, and heavy rain is possible.

One interesting thing to note is that we could expect thunderstorms to increase during the evening hours, rather than dying off. Why is this you may ask? This is because we’ll have a strengthening low level jet entering the region. This will enhance lift in the region, causing for some thunderstorms to form. Some of these storms may be strong to severe.
