Monday Update

Well, it's the first full week of summer and it's certainly going to feel like it...
Overall this week's weather will feature increasing temperatures and humidity with just isolateed thunderstorm chance... mainly on Friday. Then a much btter chnace for thunderstorms on Saturday.

Lets get into this then... overall, the pattern will be dominated by a flat ridge - really across much of the lower 48 for the work week. The main WAA zone will develop well north of us as the week rolls on with the main rain and thunderstorm zone setting up across the northern plains states into the Great Lakes.

For us, a broad southwesterly flow will develop across the Ohio Valley this week gradually warming temperatures and increasing humidity values. In addition both H7 & H5 heights will continue to slowly rise decreasing lapse rates and thereby giving us mainly dry conditions for a good chunk of this work week.
H85 temps are progged by most modeels to climb to the upper teens / lower 20s. That would translate to surface temperatures back into the lower 90s probably by Wednesday and continuing through Friday..


By Saturday, a fairly strong H5 strong will close off across the upper midwest and drift towards the Greta Lakes. This will send a cold front southeast across the Ohio Valley on Saturday with good chances for showers and storms along and ahead of the boundary.
The front should clear by Sunday with cooler and less humid conditions expected for the second half of the weekend.

Have a great day all

Later:
Jay
