With this evening's sunset, any significant likelihood of thunderstorm intensification or redevelopment has gone out the window; that's the good news - the unfortunate news is that we're not necessarily through with our rain chances quite yet, even with many communities already seeing more than an inch of rainfall over the last 24 hours alone. While the majority of the shower and thunderstorm activity during the next 6 to 10 hours will remain south hand east of the Tri-State, we should see another round of rainfall return to the Ohio Valley as early as tomorrow's morning commute.
Low pressure currently camped out atop the region will gradually drag northeastward overnight and early Thursday, rainfall developing along the back edge of the departing system will continue to affect the Tri-State though tomorrow morning and even into the afternoon. The latest model data suggests that the last of our organized rain chances should exit east of the area by 3PM or 4PM Thursday afternoon. As one round of rainfall exits, another round of humid and more mild air will begin to settle back in over the Tri-State, pushing the temperature higher and making things feel a whole lot like summer moving forward.
After seeing temperatures only reach as high as the mid to low 70s for the for the last week, one might begin to wonder when summer will return - while the official start to the summer season isn't for another two and a half weeks, summer-like temperatures will make an early entrance to the Ohio Valley. Temperatures will reach 85° and 86° under a good amount of sunshine on Friday and Saturday respectively. Higher pressure however is expected to settle in over the North Carolina/Virginia boarder over the next 48 hours or so - once that occurs, southerly winds will carry gulf heat and moisture up the Mississippi Valley and into the Tri-State. This trend isn't expected end quickly either - we should see temperatures routinely reach the mid to upper 80s fueling scattered showers and storms chances beginning Sunday through the remainder of the extended forecast.
