Heatwave Continues 100 Degree Highs Severe Weather Risk Monday
The heatwave goes into overdrive this weekend as we are still days away from a heatwave breaker that arrives late Monday. Until then we continue to roast under sunny skies in the Northeast and Middle Atlantic states. By mid morning temperatures were already at the 90 degree mark in many places and nothing will stop it from reaching the mid to upper 90s this afternoon. Some hot spots near warmer urban centers like NYC, Newark, and Philadelphia will see temperatures hit 100 degrees.
Mechanisisms to trigger off some scattered thunderstorms are not very close by and while there is always the chance that an isolated shower or thunderstorm pops up this afternoon or evening, the chances are very low and would be confined to areas well inland. Humidity levels took a small break yesterday but they will be on the march higher today and especially Sunday.
Tonight will be a steamy night with most lows in the mid 70s to lower 80s. Sunday will be the hottest day of this heatwave as the streak runs to 6 days. Highs will be in the mid 90s to around 100 degrees. Some areas around warmer urban areas like NYC Philadelphia and Boston for example could see highs exceeding 100 degrees.
Some scattered strong thunderstorms could develop late Sunday afternoon and evening in response to all the daytime heating. However Monday offers a higher risk of thunderstorms. A cold front will be approaching and it will break the heatwave after it goes by Monday night. Ahead of it will be another day of highs above 90 degrees.
Monday’s high temperatures in the lower 90s will be about 5 to 8 degrees lower than Sunday due to the approaching front and more cloud cover around which will cut back on the daytime heating somewhat. However the atmosphere will become very unstable and the Storm Prediction Center has indicated a slight risk of severe weather from Southeastern New England to Eastern Virginia. This includes all the cities in the I-95 95 corridor from Boston to Richmond.
This front will bring temperature and humidity relief to most of the area Tuesday and Wednesday before another front brings humidity and higher temperatures back Thursday. This lead front for Monday night could get hung up for awhile on Tuesday causing showers to linger around from Central NJ and Southern Pennsylvania southward. Eventually the front will move offshore and weather conditions will improve during Tuesday from north to south. Highs Tuesday will be in the 80s with gradually lowering humidity.
