The big weather story of the week in the Mid-Atlantic region will be the soaking rain event that takes place from later tomorrow into early Wednesday as strong low pressure pushes into the Great Lakes region. It has been very dry in recent weeks, but this system should produce an inch or more of rain throughout the area by early Wednesday morning. It appeared last week that there would be an influx of unseasonably cold air into the Mid-Atlantic region on the back side of this storm, but that no longer appears to be the case. Instead, Turkey Day should be dry and cool with only slightly below-normal temperatures for this time of year. The weather becomes unsettled again at week’s end and for the upcoming weekend and it looks like it will be on the chilly side.

It turned noticeably milder in the Mid-Atlantic region on Thursday as high pressure shifted offshore and the mild conditions will continue today ahead of an incoming frontal system. The front will set off some shower activity tonight, but – as has been the case in recent weeks – this will not be a significant rain event. Colder air pushes into the Mid-Atlantic region this weekend on the heels of the frontal passage. Looking ahead, a strong storm system will head to the Midwest/Great Lakes during the first half of next week and likely result in rain and wind here from Tuesday into Wednesday - and this time the rainfall may be significant.

A widespread and impressively cold air mass will cross the nation next week and reach the eastern seaboard in time for Thanksgiving Day (Thursday). A strong storm system will develop out ahead of the incoming cold air mass and it will impact a large part of the nation with rain, snow and wind on the busy travel days of Tuesday and Wednesday.

It turns noticeably milder in the Mid-Atlantic region today as high pressure pushes off the east coast and a low-level southwesterly flow of air develops in our area. After a mainly clear night, clouds will increase on Friday ahead of an incoming cold frontal system and showers are likely here on Friday night as the front passes through the DC metro region. As has been the case in recent weeks, this upcoming rain event on Friday night does not look impressive so don’t expect much relief in the dry soil conditions. Chilly air will return this weekend on the heels of the cold frontal passage and high pressure will take control of the weather into early next week.

The overall weather pattern across the nation is becoming more and more active compared to recent days and it is likely to result in a strong storm system by the middle of next week that impacts a wide area from the Great Lakes and Midwest to the Mid-Atlantic and Northeast US. In terms of temperatures, the overall pattern will flip across the nation from today’s widespread warmer-than-normal conditions to below-normal for the last ten days or so of the month of November. In fact, a widespread cold air mass with its origins in northern Canada will sweep across the nation next week from northwest-to-southeast…just in time for the Thanksgiving Day holiday. This is very likely not going to be the last cold blast for the eastern half of the nation as the colder pattern that sets up next week will likely take us to the beginning of December.

It stays chilly and dry today in the Mid-Atlantic region with high pressure remaining in control of the weather. A cold front will arrive in the area at the end of the work week and it turns milder ahead out of it on Thursday afternoon. That next front will bring us shower activity by Friday night and then another chilly air mass will follow for much of the upcoming weekend.

A cold front passed through the region late yesterday and, in its wake, today will feature chilly and increasingly windy conditions with NW winds gusting to 30 mph or so. It stays chilly and dry on Wednesday, but then turns somewhat milder on Thursday ahead of the next cold frontal system. That next front will bring us a threat of PM showers on Friday and then another chilly air mass should push into the Mid-Atlantic region for the weekend.

The overall weather pattern has been rather quiet across much of the nation in recent days, but a more active pattern appears to be setting up as we approach the middle of November. In the near term, a strong storm system will slide east across the Gulf of Mexico producing significant rainfall in the region from Louisiana to Florida where it has been quite dry in recent weeks. In addition, California and the rest of west coast will get significant rainfall (low elevations) and snowfall (high elevations) during the second half of the week. In the longer term, there are signs for a strong system by the middle of next week that can have an impact in the eastern states during a busy travel time. In terms of temperatures, this unfolding weather pattern appears to be one that can feature multiple cold air outbreaks across the northern states and this idea is supported by some teleconnection indices such as the MJO and EPO. One such cold air outbreak may very well sweep across the nation later next week…just in time to make for a cold Turkey Day for many.

High pressure is in control as we begin the new work week and will remain so making for generally quiet weather in the Mid-Atlantic region. It will be quite chilly for the next few days, but temperatures will modify later in the week. Showers will become a threat at week’s end with the approach of a strong cold front from our northwest.

Colder air will push into the Mid-Atlantic region today following the passage of a cold front and this time, the chilly air will stick around. After the threat of occasional light rain today, Canadian high pressure will take control of the weather as we head into the weekend and it’ll help to anchor this chilly air mass in place. As a result, temperatures should stay below-normal from today through Monday with the return of milder air later next week. One final note and for those interested, it looks like it’ll be chilly (40’s) and dry tomorrow in State College, PA for the noontime game between Penn State and Michigan.
