The passage of a strong cold front on Wednesday evening ushered in a much colder air mass and temperatures will remain well below-normal through Friday. Winds will stay quite strong today from a west-to-northwest direction making it feel even colder than the actual ambient temperatures. High pressure will be in charge to be the weekend and temperatures will moderate some and then a couple of low pressure systems will affect the region from Sunday night through Tuesday.

It turns milder today and stays relatively mild for the remainder of the week. Sunshine should be quite abundant each day through the remainder of the week with large-scale upper-level ridging dominating the scene across the western states.

The combination of an intensifying surface low pressure system, a strong cold front, and a deepening upper-level trough will result in the biggest rain event around here since early June. Rainfall amounts by later tonight can exceed 2 inches all along the I-95 corridor and a few thunderstorms can mix into the picture as well. In addition to the rain, the winds will become an important factor; especially, along coastal sections where a low-level jet is going to become quite intense by later today. The passage of the strong cold front later this evening will result in another cold blast for the region with temperatures on Thursday and Friday well below-normal for this time of year.

The combination of an intensifying surface low pressure system, a strong cold front, and a deepening upper-level trough will result in additional heavy rainfall across the area and there can be a thunderstorm mixed into the picture. The passage of a cold front later today will reverse temperatures from the early day highs in the 60’s to the middle 40’s by day’s end. Much colder-than-normal air will ride in on strong NW winds during the overnight hours and temperatures on Thursday and Friday will be well below-normal for this time of year. One final note, as the initial burst of cold air pours into the late today/early tonight, there can be a brief period of snow or snow showers and small accumulations cannot be ruled out in some of the far N/W suburbs.

There was some rainfall in the DC-to-Philly-to-NYC corridor on Monday which was certainly a welcome happening; however, overall totals were on the low side due to the quick movement of the low pressure system. The rain event coming from late Tuesday night through Wednesday will be quite a different story, however, and likely the biggest single rainstorm in this area since early June. Rainfall amounts can exceed 2 inches all along the I-95 corridor and a few thunderstorms can mix into the picture. The combination of a strong surface cold front, plenty of available moisture, and a deep upper-level trough that becomes “negatively-tilted” will lead to this heavy rain event
In addition to the rain, the winds will become an important factor; especially, along coastal sections of the eastern seaboard from the Carolinas to New England where a low-level jet is going to become very intense. In fact, there is the potential for winds to gusts to 60 mph late Wednesday across portions of eastern New England where the low-level jet will reach its greatest strength.
In terms of temperatures, it’ll be unseasonably mild through much of the day on Wednesday - ahead of the strong cold front - temperatures will drop sharply late in the day or early tonight on the heels of its passage. This cold air intrusion can lead to a brief period of snow in some of the N/W suburbs along the I-95 corridor where small accumulations cannot be ruled out this evening. Finally, this cold blast will result in yet another “Great Lakes snow event” for those areas just downstream of Lakes Erie and Ontario (e.g., Erie, PA, Watertown, NY).
