Most valley locations will see heat indices climb to between 100 and 105 each afternoon Wednesday through Friday, and just minor relief will be found across the Northern and Western Mountains where it will still feel like the low to mid 90s. An isolated afternoon shower or thunderstorm is possible today as the leading edge of warmer air pushes slowly northeast across the state. Another round of thunderstorms, originating over the Upper Great Lakes, may race southeast along this boundary during the day Tuesday and impact mainly the Northwest and North Central Mountains. Hot and dry conditions will bake the region Wednesday and Thursday with an increasing chance for a thunderstorm later Friday and Saturday as a cold front pushes Southeast from the Great Lakes region. Under variable amounts of clouds and some sun, highs today will range from the low 80s across the Laurel Highlands to near 90 in some parts of the Susquehanna valley and also across the Western Lowlands. Lows tonight will range through the 60s and highs Tuesday will be in the mid 80s to low 90s. Stay informed and take steps to protect yourself from heat related illness. Drink plenty of fluids and refrain from doing any strenuous activity in the sun during the peak heat of the day. $$
