We are on our way to a long duration heatwave here that will last at least into the middle part of next week For South Central Pennsylvania, North Central Maryland and for that matter all of the Northern Middle Atlantic and Northeast US Sunday will be the worst of the heat as temperatures are likely to approach 100 in many locations.
SUNDAY FORECAST HIGH TEMPERATURES
Meanwhile this afternoon we are seeing temperatures rise rather quickly as the warm front is long past us to the north and we wait for a "dry line" to approach and move through this evening. A pop up thunderstorm or two could develop into this evening but the severe weather risk today is to our north and east.
Skies will clear out tonight with most lows in the 60s. Then the heat gets turned on Friday with lots of sunshine and highs reaching into the 90s. For more on this potentially long duration heatwave and how long it will last check out the latest JOESTRADAMUS post on Meteorologistjoecioffi.com
