Bitter cold with party sunny skies, highs only reaching the mid teens
Mostly cloudy, brutal cold, lows by morning near zero
Mostly cloudy, still very cold, maybe a little snow, upper teens
Mainly cloudy, still brutal cold, some snow likely, lows near zero
Mostly cloudy, still very cold, chance for snow, mid-to-upper teens
Mostly sunny, very cold, near 20
Partly sunny, not as harsh, upper 20’s
Partly sunny, even milder, low 40’s
A large and nearly stationary upper level trough of low pressure will keep the region very cold for the next few days before some genuine warming takes place by the middle of next week. Along with the brutally cold temperatures during the weekend, there can actually be a little bit more snow as weak disturbances pass through the region.
1:45 PM | **Amazing weather across the western 2/3 of the nation; two chances for wintry precipitation in the Mid-Atlantic region this weekend**
Quite an incredible weather pattern across the western two-thirds of the nation during the past couple of days and some of the fun will spread to the eastern states this weekend. From California to Texas to the Great Lakes, there has already been an influx of brutal Arctic air and some of these areas have received a boat load of snow to go along with it. In addition, one of the worst ice storms in years is now unfolding in the region between Texas and Kentucky and icing problems are likely to hit the Mid-Atlantic I-95 big cities later this weekend…more on that threat below. Here are a few of the highlights of this amazing winter weather across the nation in the last 48 hours or so:
1) West Yellowstone, Montana reached 31 degrees below zero
2) Denver set a record low on Wednesday of 13 degrees below zero which shattered the old record by a whopping 8 degrees. Denver bottomed out at 15 degrees below zero this morning which is the coldest ever this early in the season. All of this bitter cold was accompanied by several inches of snow in the metro region.
3) Record low temperatures, frost and hard freezes hit California this morning and will again early tomorrow. Also, significant snow will fall in some of the California higher elevations later today and tonight.
4) More than 30 inches of snow fell in some areas between the Colorado Rockies and upstate Minnesota.
There are two shots at wintry precipitation in the I-95 corridor between DC and NYC during the upcoming weekend. The first shot will come late Friday night/early Saturday morning as rain winds down from one low pressure system. Temperatures will likely peak tomorrow morning and then will drop during the afternoon and evening hours on Friday in this region. By late tomorrow night, just as the precipitation is ending, it is possible that the rain mixes with or changes to sleet and/or snow in the northern and western suburbs of the big cities.
The second threat comes on Sunday and this one is a more significant threat than the first one. This appears to be setting up as a classic "cold air damming" event with very strong Arctic high pressure system situated in the Northeast US by Sunday that will act as an anchor for dense, cold low-level air which will be able to penetrate southward on the eastern side of the Appalachian Mountains. Snow, sleet and freezing rain is likely to reach the DC metro region on Sunday morning, and then Philly by Sunday afternoon, and New York City by Sunday evening. The snow will likely not be a big player in these areas during this upcoming event; however, the icing could last for an extended period as temperatures will only grudgingly rise above the freezing mark. By late Sunday night or early Monday, enough milder air should move into the big cities to change the precipitation to plain rain, but it is still a close call, and areas just to the N and W of I-95 may hold onto frozen precipitation for awhile longer on Monday. More Arctic air moves into the Mid-Atlantic region for Tuesday and Wednesday.
Finally, it is not often one sees a 6-10 day temperature forecast by NOAA (above) with colder-than-normal weather (blue) expected from coast-to-coast.
7:00 AM | **Brutal early season cold sticks around for awhile; low of -13 degrees is the coldest ever so early in the season**
Bitter cold with mostly cloudy skies, highs struggling to climb through the single digits - perhaps topping out at 10 degrees
Cloudy, bitter cold, a little evening snow possible, lows by morning near 10 below zero
Partly sunny, bitter cold, maybe a little snow, low teens for highs
Mainly cloudy, still brutal cold, lows near 5 below zero
Mostly cloudy, still very cold, upper teens
Mostly cloudy, very cold, upper teens
Partly sunny, not as harsh, low 20’s
Partly sunny, milder, upper 20’s
An amazing low temperature record was set this morning in Denver at 13 degrees below zero. Not only did this break the daily record by a whopping 8 degrees, but it also was the lowest temperature ever recorded so early in the season. A large and nearly stationary upper level trough of low pressure will keep the region very cold for the next few days before some noticeable modification takes place by early next week. Along with the brutally cold temperatures during the next 36 hours, there can actually be a little bit more snow as a weak disturbance passes through the region.
Bitter cold with snow today, breezy conditions, temperatures hold steady or drop slowly through the single digits
Cloudy, bitter cold, evening snow winds down with total snow accumulations on the order of 4-8 inches, lows by morning near zero
Cloudy, bitter cold, a little more snow possible, near 10 for highs
Mainly cloudy, brutal cold, lows from 5 to 10 below zero
Partly sunny, bitter cold, low-to-mid teens
Mostly cloudy, very cold, upper teens
Mostly cloudy, still very cold, near 20
Partly sunny, less cold, upper 20’s
A brutal Arctic air mass has plunged into the region and temperatures today will hold steady or slowly drop through the single digits. Snow will continue into the evening hours with total accumulations by later tonight on the order of 4-8 inches. Brutal cold will hang around for the next few days and the low point might be late tomorrow night/early Friday when low temperatures could approach 10 below zero.
