Altoona is not named after former New York Jet Al Toon.
At 1153PM, ET, Altoona was still reporting clear skies and a temperature of 78 degrees. There was little by way of synoptic features across the east, but the heat and humidity have led to an unstable pattern, and the lightest ripple has been able to set off thunderstorms. At this time, however, it appears that Altoona is in for a quiet night.
Tomorrow, showers and thunderstorms should manage to stay south of Altoona and Pennsylvania as a whole as the develop over the southeast. An actual real live cold front will develop in association with a trough moving through Canada. The boundary will be dragged slowly south towards Altoona, and may set off a thunderstorm late in the day on Saturday, but by and large, the weekend will be very hot and humid.
