After a cool day today, temperatures will rebound nicely on Wednesday and 70+ degrees is quite likely tomorrow afternoon in the DC, Philly and NYC metro regions. Another cold front approaches on Thursday and it is quite likely to bring more showers to the I-95 corridor, some of the rain can be heavy at times and there can be a thunderstorm mixed in as well. It'll then turn windy and cooler on Friday to close out the work week following the frontal passage.

A cold front came through the region late yesterday and high pressure will build in today as we begin the new work week. Temperatures will be much cooler today and drop down into the upper 30's overnight in some suburban locations. After becoming warmer again at mid-week, the next front is likely to arrive with showers on Thursday before settling to our south.

A cold front came through the region last night and temperatures today will hold at below normal levels in the lower 50’s for highs and it'll get quite breezy. High pressure will try to take control of our weather this weekend, but a frontal system will keep it somewhat unsettled on Sunday bringing occasional showers to the area late in the day and at night.

Low pressure will slide by to our north today and generate periods of rain in the local metro region. It actually could be just cold enough at the onset for some snow and sleet to fall across places like NE PA, NW NJ, and especially interior New York State where several inches of snow can accumulate. A couple of frontal systems will keep it somewhat unsettled around here this weekend, but it'll turn milder.

After a frosty start to the day, temperatures this afternoon will remain well below normal for this time of year despite plenty of sunshine. Clouds will be on the increase late today and tonight and this should prevent overnight low temperatures from getting as cold as they did last night. Low pressure will slide by to our north on Thursday and likely generate periods of rain in the local metro region. It actually could be just cold enough at the onset on Thursday for some snow to fall across places like NE PA, NW NJ, and especially interior New York State.

For the first time this season, temperatures will drop into the low-to-mid 30's late tonight across many suburban locations and patchy frost is possible. The lowest temperatures will be reached near morning, but the frost could form as early as midnight in outlying areas. High temperatures both today and Wednesday will hold at well below normal levels in the low-to-mid 50's (normal high at Central Park is now 61 degrees). Low pressure will slide to our north on Thursday bringing some rain to the local metro region, but it could be just cold enough at the onset for some snow in places like northeastern Pennsylvania, northwestern New Jersey and especially interior New York State.

Last winter was one in which significantly warmer-than-normal temperatures prevailed in the Mid-Atlantic region largely as a result of a strong El Nino event in the tropical Pacific Ocean, but it also featured a blockbuster blizzard that boosted seasonal values to well above normal levels in the DC-to-Philly-to-New York City corridor. It looks like the Mid-Atlantic region is going to experience a much different winter this year with respect to temperatures as it should turn out to be colder-than-normal as weak La Nina conditions in the tropical Pacific Ocean have replaced the strong El Nino. As far as snowfall is concerned, total amounts this winter are likely to reach near normal to slightly above normal levels in the I-95 corridor. In addition to the big change in temperatures, another big difference this year should be a much quicker start to winter-like weather conditions. The last couple of winters featured quite warm Decembers compared to normal, but that is not likely this year as a big flip in the overall temperature pattern to colder should take place during the middle or latter part of November.

Much cooler air pushed into the Mid-Atlantic region over the weekend and the new week will generally see temperatures stay on the cool side. In fact, a reinforcing shot of even colder air will arrive on Tuesday and patchy frost is possible late tomorrow night as overnight lows should drop well down into the 30’s.

A strong cold front will cross the region tonight and end our recent round of warmer-than-normal weather conditions. Showers are likely to accompany the approaching frontal system today and tonight and there can be a thunderstorm mixed in as well, but winds will become the biggest factor associated with this big transition in temperatures. In fact, winds should gust past 40 mph on Saturday – not a good time to rake leaves – and it’ll stay breezy on Sunday, but nothing like what is coming tomorrow. Afternoon temperatures this weekend will generally be confined to the 50’s which is quite a reversal from the 80’s earlier in the week. After a pleasantly cool start to the new week on Monday, a reinforcing shot of chilly air will arrive for Tuesday and Wednesday of next week.

The record warmth of recent days in much of the Mid-Atlantic region will slacken off today, but it’ll still feel more like summer than fall. However, changes are coming to the region and it’ll turn quite cool by the weekend. A strong cold front will cross the region tomorrow night and the weekend and early next week will be much more reminiscent of the fall season.
