7:00 AM | Still colder-than-normal for the next few days, but not as harsh; much milder on Saturday with the 50′s likely
Partly sunny, still quite cold, but not as harsh as yesterday, highs in the upper 30’s
Partly cloudy, cold, lows in the lower 20’s
Mostly cloudy, a bit colder, mid 30’s
Mostly cloudy, cold, chance for snow or rain showers, lows in the upper 20’s
Mostly cloudy, chilly, chance for snow or rain showers, low-to-mid 40’s
Partly sunny, becoming milder, low-to-mid 50’s
Partly sunny, colder, upper 40’s
Mostly sunny, milder, mid-to-upper 50’s
Our bitter cold air mass will modify some today, but temperatures will remain below normal through Friday. Milder air will push into the region on Saturday and temperatures will respond by climbing well up into the 50's. There is a one storm to monitor as the week progresses as low pressure will organize in the Southeast US. This storm will move off the Southeast US coast and then will ride to the northeast coming quite close to the I-95 corridor at the end of the work week. There is the chance that it could generate some snow or rain shower activity in the region as we close out the work week.
Looking ahead to next week, somewhat colder air will return for Sunday, but that should be rather short-lived as it'll turn milder again early next week. Later next week, however, colder air will again head towards the Mid-Atlantic region and there are signs that a significant storm could form near the east coast during the second half of next week.
7:00 AM | A bitter cold start to the day with some amazing March low temperatures, but the 50′s are on the horizon
A brutal cold start to the day with mainly cloudy skies, but the afternoon should feature partial sunshine along with very cold conditions, highs only reaching the upper 20’s (normal high at DCA is 51 degrees)
Partly cloudy, bitter cold, lows in the low-to-middle teens
Partly-to-mostly sunny, very cold for this time of year, but not as harsh as Tuesday, upper 30’s
Mostly cloudy, quite cold, lows in the lower 20’s
Mostly cloudy, cold, chance for snow showers at night, upper 30’s
Partly sunny, breezy, somewhat milder, mid 40’s
Mostly cloudy, even milder, chance for rain showers at night, low 50’s
Partly sunny, colder, mid-to-upper 40’s
Bitter cold air starts the day and temperatures will climb no higher than the upper 20’s this afternoon which is way below normal for this time of year. Some impressive morning low temperatures in the Mid-Atlantic region with, for example, Atlantic City, NJ bottoming out at 2 degrees - an all-time record low temperature for the month of March. In addition, all of the following are record lows for the month of March that were set this morning:
Dover, DE: 8 degrees
Baltimore, MD: 4 degrees (broke a record that stood since 1873 for the city of Baltimore)
Dulles Airport, VA: -1 degrees (tied)
Charlottesville, VA: 3 degrees
After another bitter cold night, temperatures will slowly modify during the second half of the week and should actually climb into the 40’s by Saturday afternoon. A storm does move up along the east coast later this week, but it appears at this time that it will only skirt the I-95 corridor with its moisture field.
6:50 AM | ***A major snowstorm for the DC metro region; snow for much of the day with significant accumulations; brutally cold tonight***
Periods of snow, heavy at times, with significant accumulations of 4-8 inches, highest amounts on the south side of the District, “thunder snow” is even possible, windy, very cold with temperatures holding steady in the lower 20’s
Gradual clearing and brutally cold with lows by morning in the single digits
Mostly sunny, very cold for this time of year, upper 20’s
Mostly cloudy, brutal cold, lows near 10 degrees
Mostly cloudy, not as cold, mid 30’s
Cloudy, breezy, cold, mid 30’s; chance for snow showers at night
Mostly cloudy, not as cold, rain showers possible, low 40’s
Partly sunny, milder, upper 40’s
A major snowstorm is underway for the DC metro region with significant accumulations expected on the order of 4-8" (highest amounts on the south side of the District). Snow will continue through much of the day, heavy at times, with “thunder snow” possible and temperatures holding nearly steady in the lower 20’s as Arctic air has arrived. Gradual clearing will take place tonight as Arctic high pressure takes control and temperatures will plunge to the single digits. Very cold conditions on Tuesday will give way to milder conditions later this week.
4:20 PM | ***Arctic air moves in overnight and temperatures will plunge; steadiest and heaviest snow is late tonight/early Monday***
Precipitation will continue to be of the scattered variety over the next several hours as an initial area of moisture pushes through the Mid-Atlantic region. A second batch of moisture will push in from our southwest late tonight and it will produce steadier and heavier precipitation and that moisture will be coincide with the colder Arctic air moving in from our north. The axis of heaviest snow from this storm will occur in the area from the DC metro region to the central Delmarva Peninsula to the Jersey Shore where totals can reach 6-12”. Snowfall accumulations will drop off quickly to the north with areas like New York City likely ending up in the 2-4 inch zone and New England largely being spared from this storm.
Now for the specifics:
NYC: light snow or a light wintry mix this evening changes to all snow later tonight. The snow continues into the mid-to-late morning hours before winding down with total accumulations on the order of 2-4 inches. Temperatures drop sharply overnight to near 20 degrees by morning and hold relatively steady tomorrow in the upper teens to lower 20’s before plunging to single digits late tomorrow night.
PHL: rain or a light wintry mix at times through the evening hours and then steadier and heavier snow should fall from late tonight to the mid-to-late morning hours on Monday. Total accumulations are likely to end up in the 4-8 inch range in the Philly metro region with the 4 inches in the northern sections of the area (e.g. northern Bucks County) and the 8 inches in southern sections (e.g., southern Chester County). Temperatures drop sharply overnight to near 20 degrees by early morning and then hold relatively steady tomorrow in the upper teens to lower 20’s before plunging to near 0 degrees late tomorrow night.
DC to the Jersey Shore: rain falls early tonight and it should then change to a wintry mix after midnight and then to all snow by early tomorrow. Snow will continue for much of the day on Monday, heavy at times, and “thunder snow” cannot be ruled out. Total accumulations are likely to end up in the 6-12 inch range throughout this region from DC to the Jersey Shore. Temperatures drop sharply overnight to near 20 degrees by morning and hold relatively steady tomorrow in the upper teens to lower 20’s before plunging to single digits late tomorrow night.
