Early 12Z Meso's suggest Friday will be cooler for much of PA with the LSV's chances of staying under 90 depending on front timing and where it stalls. Not as hot as today or tomorrow though. Tomorrow is a frying pan for the Central and Southern LSV, Lehigh Valley and SE PA while clouds and rain keep the rest of PA out of the 90's tomorrow as well. HRRR and 3K both have scattered thunder/showers for Western LSV overnight tonight as a piece of energy moves by to the N/W.
