Afternoon Rain

Wednesday started on the sunny side but as we go through the afternoon  the clouds will continue to increase. An upper level ridge will begin to slide to the east but as it does so, the nose of the jet will pull down over the Stateline, as a low pressure system slides to the east. The jet stream will provide enough lift in the atmosphere to crank out a few light showers. The jet stream will also pull in a pocket of cold air above, while temperatures at the surface will be in the mid and upper 60s. This will create a big temperature gradient and instability, allowing for a few rumbles of thunder in the afternoon.


The air mass in place is relatively dry so we won't get much rainfall today. Best timing will arrive after 3pm. Showers will stay widely scattered through the later afternoon into the early evening. The threat for rain leaving just after sunset tonight.
