After a frosty start to the day, temperatures this afternoon will remain well below normal for this time of year despite a good deal 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 showers 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 primarily in the 50's which is below normal for this time of year (normal high at DCA is now 66 degrees). Low pressure will slide to our north on Thursday bringing showers 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 in suburban locations.

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 frontal passage from later today through much of tonight and there can be a thunderstorm mixed in as well, but winds will become the biggest factor associated with this upcoming 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 be confined to the 50’s on Saturday and low-to-mid 60’s on Sunday 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 region will slacken off a bit today, but it’ll still feel more like summer than fall. However, changes are coming to the Mid-Atlantic 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.

DC Forecast: Warm air will stick around early in the week, with a cold front bringing a chance of showers on the way into the weekend. Cooler air comes in overnight Friday, leading to seasonably cool, and likely dry, fall weekend.

Forecast for DC: While Matthew was impacting the Southeast US this weekend, a strong cold front pushed through the Mid-Atlantic region and ushered in a cool air mass to start the new week. Cool and dry weather should continue through much of the week thanks to large high pressure building into the Northeast US over the next few days.

Hurricane Matthew will impact much of the Southeast US coastal region during the next couple of days from Florida to North Carolina, but it should stay away from the Mid-Atlantic region. Matthew is likely to turn sharply northeast once it reaches the South Carolina/North Carolina border region and an eventual looping track will likely prevent it from coming near the Mid-Atlantic coastline and ultimately, it could actually come back around and affect the Southeast US/Bahamas region for a second time. Meanwhile, here in the Mid-Atlantic, a strong cold front can generate some shower activity on Saturday before ushering in a cooler air mass for the latter part of the weekend and early part of next week.

Hurricane Matthew remains a serious threat to the Southeast US coastal region from Florida to North Carolina. It continues on a track towards the east-central section of Florida and it could make landfall there early tomorrow as a major hurricane (i.e., category 3, 4 or 5). If so, it would end an unprecedented streak in the US without a major hurricane strike that has lasted since October 2005 (Wilma). After its arrival in east-central Florida, Matthew is likely to move northward along the northeast Florida coastline and it should ride up along the Georgia and South Carolina coastlines as it gradually turns to the northeast. By this time, a deep upper-level trough will have an increasing influence on Matthew and this will cause an eventual turn to the east and then southeast in a looping fashion over the western Atlantic. This sharp turn and loop will likely prevent Matthew from impacting the Mid-Atlantic region this weekend, but there can still be some shower activity around here as a strong cold front heads into the eastern US.
