With high pressure still in control, the high heat and humidity will continue for another couple of days in the Mid-Atlantic region. In fact, the heat both this afternoon and on Thursday can break records in some spots with expected highs well up in the 90’s (see below). Later tomorrow, the chance of showers and thunderstorms will increase as a frontal system approaches the area from the northwest. This front will tend to stall out in the general vicinity late in the week and that will result in unsettled weather conditions on Friday, Saturday and Sunday with the daily threat of showers and thunderstorms.
On the tropical scene, “Lee” will be closely monitored in coming days as it intensifies rapidly and potentially becomes a threat to the US east coast. Lee will probably reach hurricane status later today and will likely become a “major” hurricane by the weekend…maybe even intensify all the way to a “category 5” storm.
The record high temperature today at Philly Intl Airport (PHL) is 95 degrees set in 2018 and it is in jeopardy.

A tropical wave that pushed off of Africa’s west coast several days ago has officially become tropical depression #13 in the Atlantic Ocean. This system is likely to reach named tropical storm status within 24 hours or so (will be named Lee) and very well could intensify to “major” hurricane status by the upcoming weekend. The overall environment will become increasingly conducive for intensification of the soon-to-be named tropical system in coming days as it continues on a long track across the Atlantic Ocean. Wind shear will relax as an upper-level ridge builds nearby and it’ll move over very warm waters to the east of the Lesser Antilles. Looking ahead, it appears this system may push to the northeast of the Lesser Antilles - avoiding the Caribbean Sea - and then head on a course towards the US east coast as a “major” hurricane. Whether or not this developing tropical storm ever reaches the US east coast is simply too early to call.

Strong high pressure will be in control of the weather in the Mid-Atlantic region for the next few days and it will stay hot and humid with highs well up in the 90’s. These temperatures are well above-normal for the early part of September and will challenge records in many areas through the day on Thursday. A frontal system will approach later in the week and this will increase the chance of showers and thunderstorms and the front then stalls nearby likely resulting in an unsettled weather pattern for the weekend.

On September 1st, 1859, a ferocious solar storm took place that impacted much of the planet. This ferocious solar storm is now known as the “Carrington Event”, named after the British astronomer, Richard Carrington, who witnessed the largest solar flare from his own private observatory which caused a major coronal mass ejection (CME) to travel directly toward Earth. Recent studies of solar storms have warned that these type of “Carrington Events” may not be quite as rare as once thought (e.g., Hayakawa et al). Many previous studies leaned heavily on Western Hemisphere accounts, omitting data from the Eastern Hemisphere. A super storm of the same magnitude as the “Carrington Event” in today’s world would very likely have a much more damaging impact than it did in the 19th century potentially causing widespread power outages along with disruptions to navigation, air travel, banking, and all forms of digital communication.

Strong high pressure will be in control of the weather in the Mid-Atlantic region for the next several days and that includes the long holiday weekend. Sunshine is likely to prevail each day from today through Tuesday with high pressure nearby. Temperatures in this upcoming stretch of nice weather will start off very comfortable in the Mid-Atlantic region with the high pressure stationed primarily to our west. However, after the high pressure shifts to a position off the coast, much warmer air from the middle of the country will make an advancement to the eastern states. As a result, it’ll turn quite warm around here early next week with lower 90’s likely on Monday, Tuesday and Wednesday.
