The first week of November averaged out to be quite a bit colder-than-normal in much of the eastern half of the nation, but the last couple of days have been quite pleasant for this time of the year and warmer-than-normal. It’ll remain warmer-than-normal in the Mid-Atlantic region into the day on Friday, but the passage of a strong cold front as the work week ends will usher in colder air for the upcoming weekend and it’ll set off an overall pattern change to colder-than-normal for much of the second half of the month. In fact, a reinforcing shot of cold air will arrive early next week and it could actually be accompanied by the first snow of the season in parts of the Mid-Atlantic region during Sunday night and Monday.

As a result, showers are likely on Thursday night and early Friday and there can be a thunderstorm or two mixed in as well. Much cooler air will follow this late week cold frontal passage for the upcoming weekend and a reinforcing chilly air mass will arrive during the early part of next week with the chance of snow and/or rain showers.

Temperatures dropped to near the freezing mark in many spots again late last night and there will be repeat performances late tonight and late Saturday night. The weekend will start off on the dry and chilly side and likely remain that stay way on Sunday as low pressure pushes no farther north than the North Carolina coastline. However, this system still has to be monitored during the next couple of days. A noticeable warm up is coming to much of the eastern half of the nation next week including right here in the Mid-Atlantic region. Looking ahead, there is the potential for a significant rain event in the eastern US at the end of next week. One final note...it is time once again to turn the clocks back an hour.

Last night brought the first frost of the season to many suburban locations of the DC-to-Philly-to-NYC corridor and the next few nights will likely feature low temperatures at or below the freezing mark. By the second half of the weekend, a strong storm will likely be situated off the east coast and it’ll have to be monitored to determine potential impact on the eastern Mid-Atlantic, if any, come Sunday or so. Looking ahead, it looks like a warmer-than-normal stretch of weather will return to much of the eastern half of the nation next week only to be followed by colder weather returning around mid-month.

Temperatures dropped well down into the 30’s last night in many suburban locations with the first frost of the season and, after a mostly sunny day here on Wednesday, they’ll drop to near the freezing mark late tonight. In fact, temperatures should remain at below-normal levels right through the upcoming weekend. High pressure will remain in control through the remainder of the work week, but then we’ll have to monitor the movement of low pressure later this weekend that will be pushing northward just off the east coast.

*The coldest night of the season so far is on its way and many suburban locations will experience a frost/freeze for the first time this fall.* October was a warmer-than-normal month in the Mid-Atlantic region (PHL +5.8 degrees, DCA +5.5 degrees, NYC +4.1 degrees) and overnight lows rarely, if ever, dropped into the 30's in most suburban locations...that will change not only later tonight, but also during the next few late nights as well. An upper-level disturbance can produce occasional showers around here today, but skies should clear this evening and colder air will push into the region following the passage of a secondary cold frontal system. Temperatures should stay below-normal right through the upcoming weekend.

High pressure took control of the weather in the Mid-Atlantic region on Sunday and the new work week will start off with plenty of sunshine, but with cool, breezy conditions. A cold front will slide through the region during the morning without much fanfare (i.e., dry), but its passage will usher in much colder air compared to recent weeks. There will be a couple of chances for the first frost/freeze of the season in the Mid-Atlantic region this week with likely the best chance coming late Wednesday night/early Thursday.
