Very Hot Weather On The Way Isolated Severe Storms Possible Today & Sunday
What use to be called nothing at all and then came the Excessive Heat Warning. Now we have the Extreme Heat Warning which has replaced the Excessive Heat Warning. The only remaining step is to create an Apocalyptic Hell Burning Warnings. We will leave that argument for another day. We are going to see a streak of 5 or 6 days of 90 degree plus weather which is about mid range for a heat wave. This one will last through next Wednesday before we get a bit of a break.
Today we should see a good deal of sunshine into this afternoon but there is a system coming over the top of the building high pressure ridge in the Eastern US. It will produce some scattered thunderstorms this afternoon and evening or at least the chance for some storms. Isolated severe thunderstorms are possible. High temperatures today will reach the upper 80s and lower 90s across Eastern Pennsylvania to Southern New England.

Along with the hot days come the steamy nights too. Most lows tonight will be in the low to mid 70s. Sunday will be the first day of very hot temperatures. Humidity levels will be high making it uncomfortable but dew points will not get way out of hand. Sunday highs will be in the mid to upper 90s in some places. Sea breezes will be limited to the beaches themselves.
As the ridge of high pressure strengthens Sunday a disturbance denting the flow in Southern Canada will bring the risk that some scattered thunderstorms will develop during the day, particularly across New England which is where the chance is highest. There is the chance there could be some isolated severe thunderstorms in the mix per the Storm Prediction Center.
Looking ahead to Monday Tuesday and Wednesday we see very hot and humid days. Nighttime lows will be in the 70s to near 80 degrees which is truly miserable. Days will feature plenty of sunshine and at least through Wednesday, highs will reach the mid to upper 90s in most places. Some hot spots could touch 100 degrees and I think the best chances for that will be probably Monday and Tuesday.
The risk for thunderstorms is minimal through Wednesday thanks to the stable sinking air under the upper high pressure cell over the Eastern US. A break comes Thursday as a back door front allows winds to turn more to the east and southeast. This actually could start late Wednesday along the coast but it will be enough of an east to southeast wind Thursday that temperatures will be scaled back to the 80s. No major rain or thunderstorm events are forecast during the week ahead.
