&& .SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/... As of 435 AM Sunday... Monday brings a reinforcing shot of cooler air on a weak, dry cold front that will be hardly noticeable. High pressure passes south of the area late Monday and Monday evening. A stronger reinforcing cold front and upper level short wave trough cross overnight Monday night and Tuesday. Models have come into better agreement on this being the last and strongest of several short wave troughs moving through, and that it can garner enough moisture for the chance for showers and thunderstorms, the best chance for thunderstorms in the heat of the day Tuesday midday and afternoon. The timing of the exodus of the system is such that showers and thunderstorms will die down and/or move out of the area early Tuesday evening. High pressure builds in Tuesday night for a clear, calm night, which then sets up a gorgeous day on Wednesday, with bountiful sunshine and comfortably low humidity, especially for late June. As the high exits Wednesday night, a return southerly flow of warmer and more humid air ensues. Central guidance temperatures accepted, below normal early on, then getting closer to normal Wednesday afternoon and night. && .LONG TERM /THURSDAY THROUGH SATURDAY/... As of 435 AM Sunday... Upper level low flattens this period, as surface high pressure exits. This results in a low level south to southwest flow of increasingly warm and humid air, beneath westerly upper level flow. With ripples in the upper level flow, this will bring an increasing chance for showers and thunderstorms into the middle Ohio Valley Thursday, and then throughout the area on Friday, the thunderstorms being mainly diurnally driven. The chance for showers and thunderstorms increases further Saturday, as a cold front, and stronger upper level short wave trough, approach. This feature may push on through the area on Sunday. Central guidance temperatures accepted, which are a little above normal. The latest MEX is even higher for highs Thursday and Friday. && .AVIATION /10Z SUNDAY THROUGH THURSDAY/...
