Arctic air continues to impact the eastern states here at mid-week and today will feature colder-than-normal temperatures around here along with a continued stiff westerly wind making it feel even colder than the actual air temperature. A cold front passes through the area overnight and it’ll usher in a chilly air mass for the remainder of the week with temperatures remaining below-normal Thursday, Friday, and Saturday.
In terms of space weather, a very active sunspot region unleashed three separate solar flares on Sunday, Monday, and Tuesday and each one resulted in a coronal mass ejection (CME) headed towards Earth (full story). The combination of the first two CMEs impacted the Earth last night with auroras seen around here in the Mid-Atlantic region and in unusually far south locations such as Texas, Alabama, and New Mexico. The third CME that was unleashed early Tuesday morning - the strongest solar flare of the year - could result in more northern lights on Wednesday night so be on the lookout for that if skies cooperate (and they should).

Solar cycle 25 is in its maximum phase as we approach the end of the year and it has featured numerous active sunspot regions in recent weeks. In fact, one such sunspot region known officially as AR4274 had an X5.1 class eruption early Tuesday morning...the year’s most powerful solar flare...and this follows two intense flares from the same sunspot region that took place on Sunday and Monday. The latest data that has come in on this morning’s intense solar flare suggests it was indeed accompanied by a coronal mass ejection (CME) that could reach the Earth on Wednesday, November 12th. Meanwhile, the prior two flares - which were also accompanied by coronal mass ejections - may combine into a “cannibal” CME before reaching Earth as early as later tonight.

The Arctic blast that reached the eastern US on Monday is having an impact this morning all the way down to southern Florida with numerous low temperature records across the southeastern states and Tennessee Valley region. In addition to the unusual cold in our area, winds will be quite strong today gusting to 40 mph or so which will make it feel even colder than the actual air temperatures. Temperatures do relax some at mid-week, but a chilly air mass moves in later this week following the passage of another cold frontal system.

An Arctic air mass that originated near the North Pole has infiltrated the eastern states today and it will have an impact all the way down to southern Florida by Tuesday morning. In fact, temperatures on Tuesday morning are likely to bottom out in the 30’s across the central part of the Sunshine State and the 40’s in southern Florida. At the same time, many suburban locations along the Mid-Atlantic’s I-95 corridor region from DC-to-Philly-to-NYC will feature the first hard freeze of the season with overnight lows well down in the 20’s in many spots. There is accumulating snow to go along with this early week Arctic blast with favored areas including the Great Lakes, interior sections of the Mid-Atlantic and Northeast US, and the central Appalachians where a vigorous upper-level low is helping to destabilize the atmosphere in a big way.
While there will likely continue to be colder-than-normal temperatures across the northeastern states during the second half of the week, this winter-like pattern does not look like it’ll continue through November. In fact, there are signs for warmer-than-normal conditions to cover much of the nation from next week into the following week and it may include one or more severe weather outbreaks as well. Looking farther down the road, numerous signals point to a sustained colder-than-normal period to start the winter season as we transition into the month of December.

Fifty years have passed since a major storm over the Great Lakes helped to sink the SS Edmund Fitzgerald on Lake Superior taking the lives of all 29 crew members on November 10th, 1975. When launched on June 7, 1958, it was the largest ship on North America's Great Lakes, and to this day she remains the largest to have sunk there. The Edmund Fitzgerald was in the worst possible location during the worst weather of the ferocious storm. The wind and waves from the west hit the freighter broadside as it tried to flee south to safety in Whitefish Bay. The Edmund Fitzgerald was loaded with about 26,000 tons of taconite pellets on November 9th, 1975, at Superior, Wisconsin and was bound for Detroit, Michigan when the storm hit.

An Arctic cold front passed through the region last night and the coldest air of the season pushes into the eastern US for the next couple of days. Temperatures will peak this morning in the low-to-mid 50’s for highs and then drop to the upper 20’s later tonight for overnight lows….the first hard freeze of the season in many spots. It remains unseasonably cold on Tuesday and a tight pressure gradient will result in stiff winds around here making it feel even colder than the actual air temperature. While temperatures relax at mid-week, another cold front will usher in a chilly air mass for the latter part of the week with below-normal conditions remaining on Thursday, Friday, and Saturday.

The dry weather pattern continues across the area with no appreciable precipitation expected over at least the next few days. Temperatures should reach around the 70-degree mark this afternoon and for the next couple of afternoons for daily highs.
