A cold front passed through the Mid-Atlantic region last night and today will turn out to be a cooler day than yesterday with a noticeable breeze and a mix of sun and clouds. A secondary cold front passes through the area later tomorrow and the end result of these frontal passages will be a stretch of cooler-than-normal conditions from today right through the upcoming weekend.

The European model run on Monday morning produced some stunningly high rainfall amounts of a foot or more in much of the Mid-Atlantic region for the 5-day period ending on Saturday, November 1st. Meanwhile, the Canadian model run from Monday night featured what is likely to be a hurricane (Melissa) producing accumulating snow over some of the higher elevations of the Northeast US late next week after it shifts northwest towards the New England coastline and encounters an unusually cold air mass. While odds are against either of these scenarios coming to fruition, they do suggest to me that the models are correctly sniffing out the potential for some energetic weather from later next week into the following week and there are several ingredients likely to come into play for just such a pattern. The ingredients include a powerful jet streak that will push into the western US this weekend from the northern Pacific Ocean, intense blocking in the upper part of the atmosphere that is likely to develop across central Canada by the middle of next week, a cold air intrusion into the US from Canada, and a likely hurricane over the western Atlantic Ocean.

There will be a slight chance of showers on Tuesday across the Tennessee Valley, but for the most part, the reminder of the week looks quite decent. High temperatures this afternoon should be near the 75-degree mark and likely in the low-to-middle 70’s for the rest of the week.

One cold front passed through the Mid-Atlantic region early yesterday and a second one arrives later tonight. This next cold front can cause some shower activity in the area during the nighttime hours, but nothing significant in terms of total rainfall amounts. Breezy and cool conditions will prevail on Wednesday behind the front to go along with increasing amounts of sunshine. Slightly cooler-than-normal conditions are likely to continue in the Mid-Atlantic region from Thursday through the upcoming weekend with plenty of sunshine on each day.

There have been some notable storms near the east coast during the late stages of October and early parts of November including Hurricane Sandy in 2012, the so-called “Perfect Storm” in 1991, and Hurricane Nicole in 2022 which made landfall in Florida. It is at this time of year where there can be a “last gasp” from the Atlantic Basin tropical season as water is still quite warm in places like the Caribbean Sea, and southwestern Atlantic Ocean. At the same time, there is often an increasing frequency of chilly air masses moving from Canada into the US warning us that winter is not too far away. It is this combination of a waning tropical season combined with increasingly winter-like chill that can cause volatile weather patterns in late October and early November and we could be setting up for something like that for late next week into the beginning of November.

A cooler air mass pushes into the region to start the new work week and temperatures should peak later today at a comfortable 70 degrees along with plenty of sunshine. The remainder of the week looks to be dominated by high pressure with upper 60’s to lower 70’s common for highs and lows generally in the upper 30’s to lower 40’s.

After the passage of a strong cold front, the new work week will start with windy and cooler conditions with increasing amounts of sunshine…there can be a lingering early day shower. Weak high pressure pushes into the region later today and then another cold front heads our way late on Tuesday. This next front will not be quite as strong as the system that is crossing through the region this morning, but there can be a few showers to deal with during its passage on Tuesday night. High pressure resumes control for much of the second half of the week with breezy and cool conditions to prevail.
