A cold front passed through the region early yesterday and ushered in a colder air mass as we end the work week. Low pressure will try to organize along the Mid-Atlantic coastline by late tonight, but it will be rather weak. This system can generate some rain by later tonight which can be mixed with snow for a brief time in some of the northern and western suburbs where a coating is possible. Light (plain) rain is likely tomorrow morning and then more significant rainfall is coming for Sunday. A cold front pushes through the area early Monday bringing in another chilly air mass for the early part of next week and the winds will kick up noticeably by late in the day.

A cold front passed through the region last night and ushered in a colder air mass for the next couple of days after our brief mid-week spring tease. Low pressure will try to organize along the Mid-Atlantic coastline by late tomorrow night and it could generate snow or a wintry mix before daybreak and a dusting is possible in some northern and western suburban locations. Light rain is likely in the morning on Saturday and then more significant rain will fall on Sunday. A cold front pushes through the area early Monday bringing in another chilly air mass to the Mid-Atlantic region for the early part of next week.

A bit of a tricky situation today associated with a strong frontal system as there is likely to be a burst of heavy snow possibly mixed with sleet that can result in some rapid accumulations before milder air pushes in to change the precipitation to plain rain. The most likely accumulation amount is 1-3 inches from mid-to-late morning into early-to-mid afternoon and isolated higher amounts are possible. A southerly flow on the back side of the high will boost late afternoon temperatures to above freezing and any snow that falls should change to plain rain across the region from south-to-north. A clipper system to the northwest on Tuesday could produce a snow shower around here and the rest of the week looks rather quiet.

The new work week will begin with a bit of a tricky situation as there is likely to be a quick burst of heavy snow in the DC-to-Philly-to-NYC corridor possibly mixed with sleet at times - all as a strong cold frontal system slides to the east. Snow, possibly mixed with sleet, should arrive by the mid-morning hours on Monday in DC and in the mid-to-late morning hours across the Philly and NYC metro regions. Rapid accumulations are likely before a changeover to plain rain takes place later in the afternoon.

In another long duration winter storm event, snow will tend to hang on today across eastern Pennsylvania, New Jersey and New York City and there can be small accumulations adding onto yesterday’s totals. A stretched-out wave of energy aloft is grinding its way to the east coast and it is generating enough lift in the atmosphere to produce snow in this part of the northern Mid-Atlantic region. High pressure takes back control this weekend, but it’ll remain on the cold side and the breeze will pick up noticeably.

The day will start off with freezing drizzle in most areas and as another low pressure area pushes northeast along a frontal system, snow and sleet will break out from later this morning into the afternoon. Additional accumulations of a coating to an inch or two are possible before the system winds down later in the day. High pressure takes over for the weekend, but then another low pressure area can bring us some snow or snow and rain combination on Monday.

The latest winter storm continues to pound away at the Mid-Atlantic with lots of snow north of the Pennsylvania/Maryland border and lots of icing to the south of there. There have been intense snow bands in the region from southeastern Pennsylvania to central New Jersey during the past few hours resulting in a quick piling up of snow to as much as 8 inches in some spots. The precipitation will tend to slacken off this afternoon, but this latest winter storm will turn into another relatively long duration event with redevelopment of the precipitation by tonight and there can be some impacts into the latter part of the day on Friday.

Snow has overspread the region with our latest winter storm and it will be heavy at times with quick accumulations. The snow can mix with sleet later in the morning and the precipitation may actually lighten up for a brief time later in the day. Precipitation will then re-develop later tonight likely as a wintry mix and it can actually change back to all snow on Friday before precipitation winds down in what will turn out to be another rather long duration event. Snowfall accumulation estimates of 4-8 inches for the Philly metro region with isolated higher amounts N/W and there can be an icy buildup during the second half of the storm.
