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 a little light rain 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.

Today’s storm in the Mid-Atlantic region is living up to its potential with strong, persistent E-SE winds, some serious coastal flooding, and occasional heavy rainfall that will produce 1-3 inches and isolated higher amounts. The added twist this afternoon and evening will be the likelihood for some strong thunderstorms which should rotate from the southwest-to-northeast and could include damaging wind gusts along with downpours.

Another storm system will impact the region today and it will generate strong winds, periods of rain and a possible strong thunderstorm. Rainfall amounts are likely to end up in the 1-3 inch range from this system and - given the already pretty well saturated grounds - flash flood watches have already been issued in some areas. Winds will become quite strong later today from a E-SE direction as the low pressure system approaches and potentially can gust into the 40-50 mph range. With the expected long time period of an onshore flow during this event, coastal flooding is a serious concern. The coastal flooding threat is not only a concern along the Atlantic Ocean, but also with respect to the Delaware Bay/Delaware River; especially, during tonight’s high tide. It remains quite unsettled on Saturday with lots of clouds remaining and a continuing shower threat. The weather should settle down some for Sunday although a shower cannot be completely ruled out and Monday should turn out to be a dry and cool day.

The next storm for the Mid-Atlantic region will arrive on Friday and this system will bring another soaking rainfall and strong E-SE winds for an extended period of time. As a result of the expected long and strong onshore flow of air with this next storm, coastal flooding is a big concern in all susceptible areas of the Mid-Atlantic.

High pressure will build into the area today, but its impact will be rather short-lived. Another storm system will reach us on Friday and it will generate more significant rainfall in the Mid-Atlantic region likely in the 1-3 inch range. In fact, flash flood watches may have to be issued for this storm given the already pretty well saturated grounds from the rains of earlier this week. In addition to the rain, winds will become quite strong on Friday from a southeasterly direction and potentially gusting into the 40-50 mph range. It remains quite unsettled on Saturday with lots of clouds and a continuing shower threat, but the weather should settle down some for Sunday and especially Monday.

An active weather pattern continues today with a powerful nor’easter finally starting to pull away from the New England coastline and a vigorous upper-level low over Texas that has resulted in an outbreak of severe thunderstorms and tornadoes in the Deep South. This same upper-level low will push to the east over the next 24 hours and contribute to a windy and rainy end to the week in the Mid-Atlantic/NE US.

An off-shore storm will shift away from the region today and there will be some sunshine, but its proximity will continue to result in windy conditions in the Mid-Atlantic. High pressure will build into the area on Thursday, but then another storm will form near the eastern seaboard from Friday into Saturday. This next system is associated with the energy left behind from the storm that pounded the west coast on Sunday and Monday and it could bring more significant rain and wind to the Mid-Atlantic region. Looking ahead, a cold front is likely to push our way by the middle part of next week.
