A fresh, cold and dry air mass pushed into the region last night following the passage of a cold frontal system. This air mass is being anchored today by strong high pressure over New England and it helps to set the stage for plenty of frozen precipitation around here from later this evening into early Tuesday. As moisture first arrives, it’ll likely be cold enough for snow, but then a thin layer of above-freezing air will push in aloft and result in a changeover of the precipitation to sleet which may last for an extended period of time during the overnight hours. By late tonight, the sleet may mix with or change to rain and with ground temperatures at or below freezing, any rain that falls will freeze on untreated surfaces. In fact, temperatures will be reluctant to climb above freezing for most of the morning on Thursday; especially, across the N/W suburbs. Bottom line...Thursday AM commute can be quite a mess with slippery road conditions possible throughout the region. A repeat performance is likely this Saturday and Saturday night with a ”snow-to-sleet-to-freezing rain-to-plain rain” scenario on the table. Looking ahead, accumulating snow is likely to threaten the Mid-Atlantic region during the early-to-middle part of next week.

A fresh, cold and dry air mass pushed into the region last night following the daytime passage of a cold frontal system. This air mass is being anchored today by strong high pressure over New England and it helps to set the stage for snow here later tonight which can mix with sleet by morning. Snow and sleet in the morning can mix with or change to rain which can freeze on untreated surfaces…expect slippery road conditions for the AM commute. Enough milder air pushes in by mid-day on Thursday for the precipitation to wind down as plain rain and afternoon temperatures should peak near 40 degrees. A repeat performance is possible this weekend with a ”snow-to-sleet-to-freezing rain-to-plain rain” scenario on the table. Looking ahead, there is an accumulating snow threat for the Mid-Atlantic region during the early-to-middle part of next week.

An active weather pattern will likely bring three winter storm systems to the Mid-Atlantic region during the next week or so. The first system will bring a mix of precipitation to the DC-to-Philly-to-NYC corridor from late tomorrow into Thursday morning and all areas are likely to experience slippery road conditions for the Thursday AM commute. A thin layer aloft of slightly above-freezing air will push into the region on Wednesday night, and this will play a big role in precipitation types ranging from snow-to-sleet-to-freezing rain to just plain rain. Always a difficult forecast when dealing with these thin layers, but my initial feeling on this mid-week threat in the I-95 corridor is as follows: DC metro region will get hit hard with freezing rain leading to a significant ice-buildup, the Philly metro region may have an extended period of sleet, and the NYC metro region may actually see snow for much of the event that certainly can mix with sleet at times. A similar weather event could unfold for the upcoming weekend in the Mid-Atlantic region with a “snow-to-sleet-to-freezing rain-to-plain rain” scenario on the table. Looking past the weekend system, there very well may be an accumulating snow threat for much of the Mid-Atlantic region by the middle of next week and it can be significant.

The overall weather pattern across Colorado will remain on the mild side for the next few days little chance of any rainfall. It does turn moderately cold this weekend, and the chance of rain (or snow) showers will return to the area.

It stays very mild around here for the next few days with daily highs near or slightly above the 70-degree mark. The weather becomes rather unsettled as well with an increasing chance of showers and thunderstorms as we head through the middle and latter parts of the week.

In just the next week or so, it appears there will be as many as three opportunities for snow, ice and rain in the Mid-Atlantic region. The first such opportunity will come from later tomorrow into Thursday and this could turn out to be quite a mess around here for the Thursday AM commute with some accumulations of snow and sleet. The setup will include a cold frontal passage today that will be followed by an influx of fresh cold and dry air in the overnight hours while at the same time moisture begins to gather over the Tennessee Valley. This dense, cold air mass will be quite reluctant to give up its ground on Wednesday night and Thursday as the moisture arrives and surface temperatures will be slow to climb to above freezing levels until mid-day Thursday.
Looking ahead, there can be a repeat performance in the Mid-Atlantic region during the upcoming weekend with “snow-to-sleet-to-freezing rain-to-plain rain” on the table. Looking even farther ahead, there may be an accumulating snow threat by the middle of next week in this on-going very active weather pattern.

February is now a few days old, and it looks like it will be a very active month with plenty of cold air around and it is likely to feature a polar vortex “split” and high-latitude blocking. There should be plenty of opportunities for snow, ice and rain in the Mid-Atlantic region as we progress through the month with just the next week or so likely to feature as many as three precipitation events. The first opportunity comes at mid-week, and it may turn out to be the first significant icing event in quite awhile for much of the Mid-Atlantic region with possible snow on the front end and plain rain on the back end. A similar scenario may take place this weekend with frozen precipitation possible on the front-end of the next storm system and plain rain on the back end. A third storm may threaten by the middle of next week and this one should have more cold air to work with raising the chance of accumulating snow in the Mid-Atlantic region.

It was a little past 1 AM on February 3rd, 1959 when American musicians Buddy Holly, Ritchie Valens and J.P. “The Big Bopper” Richardson were killed in a plane crash near Clear Lake, Iowa along with pilot Roger Peterson. Weather conditions were certainly contributing factors in the plane crash as there was poor visibility on that cold night with snow blowing across the runway. Hours before, Holly and his tour mates were on the eleventh night of their “Winter Dance Party” tour through the snow-covered Midwest. It was a Monday and a school night, but 1,100 teenagers crammed into the Surf Ballroom in Clear Lake, Iowa for two sold out shows with the second one ending around midnight. The event later became known as “The Day the Music Died” after singer-songwriter Don McLean referred to it as such in his 1971 song “American Pie” which paid homage to the tragedy of February 3rd, 1959.
