Rain will become heavy at times later today and continue into early Friday morning and there can be a thunderstorm or two mixed into this soaking rain event. A wintry mix is possible for a little while longer early today in some of the normally colder far northern and western suburbs. It’ll turn milder later in the day and winds will become increasingly strong pushing in the milder air. A powerful Arctic front will arrive here on Friday morning and temperatures will drop dramatically on its back side – perhaps by more than 30 degrees in a short period of time. Winds will remain strong behind the front shifting to a W-NW direction and gusting to 50 mph or so. A quick freeze-up is possible on Friday of any wet spots that remain on the roadways from the prior rainfall. A burst of snow is likely immediately behind the frontal passage which can quickly generate a coating to an inch or two - adding to the potential difficulty in overall travel conditions. Temperatures may bottom out in the single digits by early Saturday morning (Christmas Eve) and the frigid weather will continue through Christmas Day (Sunday). Winds will stay quite strong through much of the weekend adding to the suffering of the upcoming “face-slapping” Arctic cold.

The core of an intensely cold Arctic air mass is now getting ready to plunge southward to Texas by later tomorrow and then it’ll shift to the eastern states on Friday. Numerous low temperature records are likely to be set over the next couple of days as this air mass makes its way across the nation. Blizzard conditions will accompany this advancing Arctic air outbreak over much of the eastern half of the country with the Great Lakes region likely to experience some of the worst weather with an extended period of extreme conditions from Friday into late weekend.
The powerful Arctic frontal system that represents the leading edge of this intensely cold air mass will reach the DC-to-Philly-to-NYC corridor during the late morning/mid-day on Friday. Temperatures will drop dramatically in the wake of the frontal passage some 30+ degrees in a short period of time. Any wet spots on roadways from prior rainfall could freeze-up in a hurry. There will be very strong wind gusts on Friday and a burst of snow is likely immediately behind the frontal passage that can produce a quick coating to an inch or two. A frigid weekend will follow with Christmas Eve (Saturday) and Christmas Day (Sunday) the coldest in many years across much of the eastern half of the nation. Single digits are likely in many spots along the I-95 corridor both on Saturday and Sunday mornings.

Strong low pressure will develop on Thursday in the eastern US and it will push much milder air into the Mid-Atlantic region on increasingly strong S-SE winds. There is a chance, however, that enough cold air will be lingering around early tomorrow to result in a brief period of snow and/or ice in some of the northern and western suburbs; however, temperatures should climb to well above freezing levels by later in the day. The rain can indeed fall heavily at times from later tomorrow into Friday morning and a thunderstorm or two cannot be ruled out. This surge of mild air will likely peak on Friday morning with temperatures likely near 50 degrees, but that warmth will disappear abruptly during the afternoon hours on Friday.
The strong Arctic frontal system that represents the leading edge of an intensely cold Arctic air mass will reach the DC metro region likely during the late morning hours on Friday. The passage of this powerful Arctic surface cold front will not go unnoticed. On the table will be plunging temperatures on the order of 30+ degrees in a short period of time, powerful and potentially damaging wind gusts, a possible “flash-freeze”, and even a burst of snow that can put down a quick small accumulation. A frigid weekend will follow with Christmas Eve (Saturday) and Christmas Day (Sunday) the coldest for the holidays in many years across much of the eastern half of the nation. Single digits are certainly a possibility in the N/W suburbs along I-95 corridor both on Saturday and Sunday mornings.

The core of an intensely cold Arctic air mass is now penetrating the northwest and north-central parts of the nation, and it will drop southward towards Texas during the next 48 hours. After that, the Arctic air mass will shift to the east and reach the eastern seaboard by late Friday. Numerous low temperature records are likely to be set over the next few days; especially, in the central US from the Canadian border to the Mexican border. Blizzard conditions will accompany this advancing Arctic air outbreak during the next few days over many sections of the country with the Great Lakes region likely to experience some of the worst with an extended period of extreme conditions from Friday into much of the upcoming weekend.
The strong Arctic frontal system that represents the leading edge of this intensely cold air mass will likely reach the DC-to-Philly-to-NYC corridor during the mid-day and afternoon hours on Friday. The passage of the powerful Arctic front will not go unnoticed. On the table will be plunging temperatures on the order of 25 or 30 degrees in a short period of time, powerful and potentially damaging wind gusts, a possible “flash-freeze”, and even a burst of snow that can put down a quick small accumulation of a coating to an inch or two A frigid weekend will follow with Christmas Eve (Saturday) and Christmas Day (Sunday) the coldest in many years in much of the eastern half of the nation. Single digits are certainly a possibility along the I-95 corridor both on Saturday and Sunday mornings.

A major Arctic outbreak reached the northern US on Monday and the surface front marking the leading edge of this air mass will likely makes its arrival here on Friday afternoon. Before we get there, a soaking rainfall event is likely here from early Thursday into early Friday and it’ll turn very windy and noticeably milder. In fact, on Friday morning – ahead of the advancing Arctic frontal system – temperatures could peak in the 50’s and winds will be quite strong from a south-to-southeast direction.
Following the passage of the Arctic front on Friday afternoon, winds will remain strong shifting to a W-NW direction and temperatures will plunge by as much as 25 or 30 degrees in just a couple of hours. This sharp drop in temperatures can lead to a “flash freeze” of any lingering wet spots on roadways. In addition, a burst of snow is possible immediately following the frontal passage which can even put down small accumulations in some spots as the Arctic air pours into the region in a still very unstable atmosphere. Christmas Eve (Saturday) and Christmas Day (Sunday) will be very cold throughout the eastern US with some of the coldest weather conditions for these two days in many years. Single digits are on the table in suburban locations both on Saturday morning and again on Sunday morning.

A major Arctic air outbreak has reached the interior northwest and north-central states and it will become quite a newsworthy event in coming days. This widespread and intensely cold Arctic air mass will drop southward to Texas by later Thursday and then shift to the east on Friday reaching the eastern seaboard by Friday night. Numerous low temperature records are likely to be set over the next few days; especially, in the central US from the Canadian border to the Mexican border.
At the leading edge of the Arctic air mass will be a powerful surface frontal system that will be very active as it crosses the Great Lakes/Midwest/Ohio Valley from west-to-east. This Arctic front will produce blizzard conditions from the Plains all the way to the Appalachians as it treks west-to-east during the next few days. The powerful Arctic front is likely to arrive in the DC-to-Philly-to-NYC corridor region on Friday afternoon and its passage could be quite dramatic.
Winds will be very strong and potentially damaging for much of the day on Friday in the Mid-Atlantic region both ahead of the Arctic front (S-SE direction) and behind it (W-NW direction)…not a good time for inflatable outdoor decorations. Temperatures will plunge as plunge as much as 25 or 30 degrees behind the front in just a couple of hours from the mild 50’s in the morning to the 20’s by day’s end. This sharp drop in temperatures can result in a “flash freeze” of any lingering wet spots on roadways from prior rainfall.
In addition, a burst of snow is possible immediately following the frontal passage which can even put down small accumulations in some spots as the Arctic air pours into the region in a still very unstable atmosphere. Christmas Eve (Saturday) and Christmas Day (Sunday) will be very cold throughout the eastern US with some of the coldest weather conditions for these two days in many years. Single digits are on the table in suburbs along the I-95 corridor both on Saturday and Sunday (Christmas) mornings.

A major Arctic air outbreak will blast into the US this week. The core of the frigid air will drop southeastward on Monday from western Canada into Montana/North Dakota and then dive southward to Texas by later in the week. The Arctic air mass will then push to the northeast later Friday with a powerful frontal system at the leading edge of the incoming cold air mass. The powerful Arctic front will likely arrive in the Mid-Atlantic’s I-95 corridor on Friday afternoon and its passage could be quite dramatic. Powerful winds are likely, temperatures will drop sharply as much as 30 degrees in a few hours, there can be a quick freeze-up or “flash-freeze” of any lingering wet spots on roadways. In addition, a burst of snow is possible which can put down small accumulations as the Arctic air pours into the region in a still very unstable atmosphere. Christmas Eve (Saturday) and Christmas Day (Sunday) will be very cold throughout the eastern US with some of the coldest weather conditions for these two days in many years. Single digits are on the table in suburban areas both Saturday and Sunday mornings.

The coastal storm that spread precipitation into our region on Thursday will gradually push away this morning and there will be clearing skies in the afternoon. High pressure edges this way and will control the weather through the weekend and right through the first half of next week. Temperatures will average below-normal for this time of year with highs generally doing no better than the lower 40’s during the next several days despite plenty of sunshine. Late next week, a storm can form near the east coast at the leading edge of an incoming Arctic air mass…something we’ll need to monitor in coming days. Christmas weekend to follow is looking quite cold in the eastern half of the nation.

A record-breaking Arctic air outbreak will blast into the US next week. This frigid air mass will spread south and east next week - no doubt breaking numerous low temperature records along the way - and reach the eastern states by week’s end. A very cold Christmas weekend is in store for much of the eastern half of the nation. In fact, Christmas Eve and Christmas Day (Saturday, Sunday) could turn out to the coldest such in many years across much of the eastern half of the nation. With respect to snow chances, there may very well be a major storm system that forms on the leading edge of the Arctic blast at the end of next week in the eastern US which raises hope for a white Christmas in many locations.
Meanwhile, in the short-term, the major storm that has pounded much of the country in recent days with blizzard conditions in northern areas and severe weather in southern states is now impacting the Mid-Atlantic region and Northeast US. Rain will be the dominate precipitation type from here on out in the immediate I-95 corridor to go along with increasingly strong easterly winds. Significant snow is on the table for upstate PA, upstate NY, and the interior part of New England with some spots likely to receive more than a foot. Following this storm, much of the nation will experience colder-than-normal conditions this weekend with virtually coast-to-coast below-normal temperatures.
