This may sound familiar, but there is the chance that a storm system will travel eastward this weekend from the Deep South to the east coast, and it could threaten the Mid-Atlantic region with snow, ice and/or rain. The overall weather pattern will be quite active for much of the country in coming days with multiple storm systems to deal with and impacts from coast-to-coast. One storm system came ashore on Monday along the California coast, and it will push to the Colorado Rockies by the middle of the week. At the same time, a frontal boundary zone will start to set up from the Northern Plains to the northeastern states, and it will be the focus area for multiple disturbances leading to some snow and ice on its northern side and rain to the south.
By the early part of the weekend, another storm system will begin to take shape over the south-central US with its moisture field starting to expand. Much like the scenario that played out last weekend, this low pressure system will trek in a general eastward direction - riding along the subtropical jet stream - and potentially can reach the Mid-Atlantic coastline by late Sunday. With cold air in place and support in the upper atmosphere, this system could intensify at that point and become a threat for accumulating snow in at least portions of the Mid-Atlantic region by the latter part of the weekend.

A very windy day is expected in the Denver metro region with gusts of 45 mph or so on the table raising the concerns for wildfires. It turns colder as we reach mid-week and the chance for some snow will be on the increase by the time we get to tomorrow night, Thursday and Friday.

After a cloudy and foggy morning, skies should partially clear this afternoon and it’ll become milder with highs well up in the 50’s. A frontal boundary zone will set up right nearby at mid-week and result in unsettled weather around here for the remainder of the week with showers likely on multiple occasions. Looking ahead, we may have to deal with another late weekend storm system in the Mid-Atlantic region...more on that threat during the next few days.

After a cloudy and foggy morning, skies should partially clear this afternoon and it’ll become milder with highs well up in the 40’s. A frontal boundary zone will set up right nearby at mid-week and result in unsettled weather around here for the remainder of the week with showers likely on multiple occasions. This front will drop to our south at times (as a backdoor cold front) keeping a lid on any warmup around here. Looking ahead, we may have to deal with another later weekend storm system in the Mid-Atlantic region...more on that threat during the next few days.

The overall weather pattern looks quite warm for the remainder of the week with 70-degree highs each of the next couple of days and then likely well up in the 70’s on Thursday and Friday. The pattern becomes unsettled as well with the chance of showers for much of the second half of the week.

A storm system that came ashore in California at mid-week is crossing the southern states and will spread its precipitation shield into the Mid-Atlantic region from later Sunday into Sunday night. The air mass will initially be only marginally cold enough to support frozen precipitation; however, dynamical cooling in the atmosphere associated with a strong upper level jet streak should result in more favorable conditions for snow by Sunday night across eastern Pennsylvania, New Jersey, and New York City and up to a few inches are on the table. To the south of the PA/MD border, rain is likely to be the predominate precipitation type in the immediate DC metro area with no accumulations expected. However, snow and/or ice can mix in across some of DC’s far northern suburbs, and the northern part of Maryland that is close to the Pennsylvania border and northern Delaware can certainly see some small accumulations.
