It is not all that unusual for the “last hurrah” of an Atlantic Basin tropical season to be followed by an influx of winter-like cold into the central and eastern US and, in some cases, it is a “pattern-changing” type of event. One such example of this kind of scenario unfolded with Hurricane Sandy at the end of October during 2012 which was then followed by a colder-than-normal November in most areas east of the Mississippi. (In fact, cold air actually wrapped into Hurricane Sandy with as much as 3 feet of snow in West Virginia during that event). It appears a tropical system now forming over the Caribbean Sea may cross the Yucatan Peninsula by early next week and it then can take a turn to the northeast. Hopefully, this tropical system will weaken during its encounter with the Yucatan Peninsula and before a possible northeast turn towards the state of Florida. At the same time, cold air will be charging southeastward from Canada into the central states and other very impressive-looking cold shots are destined to work their way into the central and eastern states later in the month.

Some of the lowest temperatures so far this fall season have greeted this early Wednesday morning with overnight lows along the Mid-Atlantic’s I-95 corridor ranging from the upper 20’s to lower 30’s. It stays quite cool today despite plenty of sunshine and then temperatures drop to quite cold levels again late tonight. On Thursday, a front and its associated weak low pressure system will approach from the west and it will produce some shower activity in the Mid-Atlantic region from late in the day to early tomorrow night. The best chance of showers will come south of the PA/MD border in the region from DC-to-Delmarva Peninsula with nothing more than a shower or two likely across the Philly-to-New York City corridor. High pressure returns to the region for Friday, Saturday, and Sunday leading to a 3-day stretch of dry and cool weather conditions.

A chilly air mass will flood the Mid-Atlantic region today on the heels of a frontal passage and it can lead to the coldest night of the season so far. Temperatures today will be limited to the low-to-mid 50’s for afternoon highs and then they’ll likely drop to near 30 degrees in the late night hours. In addition to the chill, winds will become quite a factor today with gusts up to 35 mph or so out of the northwest. Temperatures late tomorrow night are likely to fall to the lower 30’s and then clouds will dominate the skies on Thursday as the next front approaches and it can be accompanied by some more rain shower activity.

A cold front will cross the region today and then a secondary cold front pushes through early Tuesday with high pressure to follow for the mid-week. Temperatures will climb into the mid-to-upper 60’s later today, but will be confined to the lower 50’s for highs on Tuesday and likely near 50 degrees on Wednesday and Thursday. Temperatures late tomorrow night/early Wednesday can drop the lowest levels so far this season with overnight lows near the 30-degree mark in many spots. Another frontal system arrives on Thursday and it can bring more showers to the region.

The first widespread rain event in many weeks is coming to the Mid-Atlantic region from later Sunday into early Monday. Strong low pressure will push up to the northwest of here during the latter part of the weekend and it may even be able to draw some tropical moisture into the region from Hurricane Rafael. The likely rainfall amounts here should be in the 0.25 to 0.50 inch range between later Sunday and early Monday. The weather pattern returns to dry and comfortably cool again during the first half of next week, but more rain is possible by Wednesday night or Thursday.

A weak cool front pushed through the region last night and it’ll stay quite warm for today and then turn slightly cooler on Friday and Saturday. Looking ahead, the late weekend may actually feature the first widespread rain event in several weeks for the Mid-Atlantic region. Strong low pressure will push up to the northwest of here during the latter part of the weekend and it may even be able to draw some tropical moisture into the region from Hurricane Rafael (now a “cat 2” over the Gulf). The likely rainfall amounts here should be in the 0.25 to 0.50 inch range between later Sunday and early Monday.

Temperatures today should soar to near 80 degrees for afternoon highs which is in record-breaking territory for many locations including at Central Park (NYC) where the record is 75 degrees (2022). A cool front pushes through the region later tonight and it turns slightly cooler for the next couple of days with some sunshine expected.
Looking ahead, the weekend may actually feature the first widespread rain event in several weeks for the Mid-Atlantic region. Strong low pressure will push up to the northwest of here and this system may draw some tropical moisture (Hurricane “Rafael”) into the Mid-Atlantic region...something that would be quite beneficial to our moisture-starved part of the country.

A warm front lifted northward through the region late yesterday and it’ll turn warmer around here for today and Wednesday. After high temperatures near 60 degrees to start the new work week, they’ll climb to the middle 70’s today and then to near 80 degrees on Wednesday which will be in record-breaking territory for some spots. The next front to arrive here will be a cold front and its passage will usher in slightly cooler air for the late week time period.

The calendar has flipped to November and the first full week of the new month will feature some wild weather across the nation. First, a severe weather outbreak is likely later today into late tonight across the nation’s mid-section and this includes the threat of tornadoes from Texas to Missouri. Second, accumulating snow is likely across the Rocky Mountain States, and it can be significant during the latter part of the week across Colorado and New Mexico. Finally, a surge of tropical activity has begun in parts of the Atlantic Basin and a tropical system now intensifying over the Caribbean Sea is likely to become a hurricane by later in the week as it heads towards the Gulf of Mexico.

A warm front will lift northward through the region later today and it’ll turn warmer around here for Tuesday and Wednesday. After high temperatures in the lower 60’s to start the new work week, they’ll climb well into the 70’s on Tuesday afternoon and to near 80 degrees on Wednesday. The next front to arrive here will be a cold front and its passage will usher in cooler air for the late week time period. Both of these frontal systems – warm front early in the week and cold front at mid-week – should pass through the Mid-Atlantic region without much, if any, in the way of rainfall.
