     Our weekend system still delivering light rain in the east will gradually exit stage right. Quick on the heels of that system is another low pressure system crossing the Ohio River Valley & reaching the Appalachians this afternoon. We'll keep the threat for showers and thunderstorms this afternoon into our overnight.

     High precipital water values mean that plently of moisture is available to these storm systems. Any storms that do make it into our area could produce heavy rainfall. With soils still for the most part saturated, heavy rainfall could create flashy water problems like ponding on roadways. Storms may also produce damaging winds and hail into the overnight. We'll stay in the warm sector tonight, keeping a muggy feel to the air. Lows will be in the mid  to upper 60s.

     Tuesday we'll see a few peaks of sunshine as upper level ridging helps to clear out any leftover muck. It'll be summer solstice with max sun angles in the northern hemisphere. We'll also be in the warm sector of a cold front crossing the Midwest. So a generally southwesterly air flow will pull lots of warm humid air into our area. This along with max solar intensity plus longest day of the year means temperatures will be about ten degrees hotter than today. So we have to keep a slim chance for these factors to combine to allow for some late day convective thunderstorms for our area.

     Cold front will cross our area Wednesday & Wednesday night. Again we'll have a chance for heavy rainfall  and scattered thunderstorms. Highs will be in the mid to upper 80s. Lows will still be in the mid to upper 60s. We'll keep isolated thunder through the rest of the work week. Weather will calm down with sligthly cooler temps in time for the weekend.
