The upper-level flow over North America is undergoing a significant transition and this will lead to a stormy weather pattern next week in a good portion of the country. One storm will ride up the east coast later Monday into Tuesday likely bringing rains to the I-95 corridor region from DC-to-Philly-to-NYC. There is an outside chance that if the precipitation sneaks in early enough on Monday, there may be a little sleet and/or snow in parts of the Mid-Atlantic region for a brief time. Another storm will pound the western states early next week producing snow in many of the higher elevation locations.
The strongest storm of the week will affect the Upper Midwest, Northeast and Mid-Atlantic region on Christmas Eve (Wednesday) and into Christmas Day. The Mid-Atlantic region will be on the warm side of this storm with periods of rain likely on Wednesday possibly heavy at times. There is even the chance for some thunderstorm activity to form on Wednesday; especially, in the southern and eastern portions of the Mid-Atlantic (e.g., Delmarva Peninsula, coastal New Jersey). The winds will become quite strong on Wednesday and they will remain strong on Wednesday night and Thursday following the system. Colder air will move in behind the storm on Wednesday night and Thursday and snow showers are possible in the Mid-Atlantic region to go along with the strong winds. A significant lake-effect snow event is likely in the wake of the storm on Christmas Day in the typical areas just downstream of the Great Lakes (e.g., western NY).
7:00 AM | Weekend looks rather quiet…next week looks stormy and wet; strong winds possible Christmas Eve and Christmas Day
Mostly cloudy, cold, highs in the low 40's
Mostly cloudy, cold, lows by morning near 30 degrees
Partly sunny, cold, upper 30’s
Mostly cloudy, cold, cannot rule out a rain or snow shower, low 30’s
Mostly cloudy, cold, maybe a rain or snow shower, low 40’s
Mostly cloudy, cold, PM rain likely, low-to-mid 40’s
Mostly cloudy, milder, still the chance for some rain, near 50 degrees
Cloudy, becoming windy with periods of rain, heavy at times, mild, low-to-mid 50’s
After another cold day to close out the work week with limited amounts of sunshine, low pressure will pull out of the southern states this weekend and head towards the Mid-Atlantic coastline. This storm will not intensify appreciably as it reaches the east coast and its limited precipitation field will stay to the south and east of the I-95 corridor region.
The overall weather pattern next week looks quite active as the atmosphere over North America undergoes some significant changes. One storm is likely to ride up the east coast later Monday bringing some rain to the I-95 corridor and then another and even stronger storm is likely to affect the Northeast US and Upper Midwest on Christmas Eve (Wednesday). Odds heavily favor rain in the I-95 corridor with the second storm and it could be a very windy and soaking rain event - possibly even including some thunderstorm activity. On the back side of that mid-week storm, it’ll turn colder around here on Wednesday night and Christmas Day with possible snow showers, but the biggest factor of all may very well be the continuing strong winds. The overall weather pattern will likely turn much colder as we approach New Year’s Day.
7:00 AM | Chilly to close out the work week…weekend looking rather quite…next week looking very noisy
Clouds and limited sun, breezy, cold, highs in the lower 40’s
Partly cloudy, cold, lows by morning in the lower 30’s
Mostly sunny, cold, low 40’s
Partly cloudy, cold, near 30 degrees
Partly sunny, cold, cannot rule out a couple of rain and/or snow showers at night, near 40 degrees
Partly sunny, cold, low 40's
Mostly cloudy, cold, rain likely, low-to-mid 40’s
Mostly cloudy, not as cold, still the chance for some rain, upper 40’s
Colder air has returned to the region following the passage of a frontal system early yesterday. Today and Friday will be slightly colder-than-normal in the Mid-Atlantic region, but dry on each day along with limited sunshine. Over the weekend, low pressure will pull out of the southern states and head towards the Mid-Atlantic coastline. It appears that intensification of this system at the coastline will be quite limited and that its precipitation field will generally stay southeast of the I-95 corridor.
The overall weather pattern looks very active next week as the atmosphere over North America undergoes some significant changes. One storm could ride up the east coast on Monday bringing a soaking rain event to the I-95 corridor and then another and even stronger storm is likely to affect the Northeast US and Upper Midwest by Christmas Eve (Wednesday). Odds favor rain in the I-95 corridor with the second storm and it could be another soaking rain event possibly even including some thunderstorm activity. On the back side of that mid-week storm, winds could howl next Wednesday night and again on Christmas Day and there will likely be a significant temperature plunge. The overall pattern looks to get progressively colder as we move from Christmas Day to New Year's Day.
7:00 AM | Cold front ushers in colder air for tonight, tomorrow and Friday…weekend storm looks rather weak, but still time for that to change
Partly sunny, becoming breezy, cool, highs not far from 50 degrees
Partly cloudy, turning noticeably colder, maybe a rain or snow shower, lows by morning in the low-to-mid 30's
Partly sunny, breezy, cold, low 40's
Partly cloudy, cold, near freezing for lows
Mostly sunny, cold, near 40 degrees
Increasing clouds, cold, chance for rain and/or snow at night, near 40 degrees
Mostly cloudy, cold, chance for rain and/or snow, near 40 degrees
Mostly cloudy, cold, maybe some rain and/or snow shower activity, near 40 degrees
A warm front pushed through the region on Tuesday and a cold front has followed closely on its heels. After a relatively mild day today with highs near 50 degrees, colder air will become noticeable tonight and then the next two days will return to colder-than-normal conditions. The weekend will feature low pressure moving from the southern states towards the Mid-Atlantic coastline. The main disturbance involved with this potential Mid-Atlantic storm is just now moving onshore in California. Latest indications are that this system will remain rather weak this weekend and that any potential precipitation event around here would be only of the "light-to-moderate" variety; however, there is still time and reason to believe that this can change. There is some hinting that an inverted trough of low pressure will try to throw additional rain/snow shower activity our way on Monday and then a stronger storm is possible on Christmas Eve (next Wednesday). As of now, odds favor rain from that mid-week storm in the Mid-Atlantic region and then it would likely set up a cold pattern around here for the week between Christmas Day and New Year's Day. Stay tuned...an active pattern setting up with a lot going on over the next 7-10 days.
