A cold front slipped through the region last night and it’ll be sunny today as high pressure builds into the region and seasonably cool. Winds will become quite noticeable today, but then should calm down in the overnight hours and this will allow temperatures to fall to the lower 40's for late night lows. High pressure stays in control over the next couple of days and then we’ll have to watch an area of moisture in the Deep South that can result in clouds and rain around here over the weekend.

A cold front will approach the region later today and after a couple of scattered showers this morning and mid-day, the rain will become more widespread for the mid and late afternoon and it should continue into early tonight. Clearing skies will follow late at night and the next two days promise to be generally sunny and seasonably cool days for this time of year. Another front may approach the region at the end of the work week; the frontal passage could be on the dry side, but it is too early to write off the chance of showers from late Friday into early Saturday.

A tropical system continues to slowly intensify over the Gulf of Mexico and has now reached named (Nestor) tropical storm status. This system is moving to the northeast and will approach the northern Gulf coast later today and tonight and then move inland across the southeast US this weekend. By late Sunday, this tropical storm will likely move offshore somewhere near the Outer Banks of North Carolina and it could generate some rainfall on its NW side in the Mid-Atlantic region late Saturday night/Sunday morning. Looking in the extended time period, some impressive cold air outbreaks are likely to impact the central and eastern US during the last week of October and the first week of November – perhaps leading to quite a chilly Halloween for lots of people across the eastern half of the nation.

High pressure will gradually build into the region today and the impact of the just-departed coastal storm will diminish as the day goes on. Winds will start the day on the brisk side - though not as bad as yesterday - and they’ll become nearly calm later tonight. With clear skies and nearly calm winds in the overnight, temperatures are likely to drop to the mid and upper 30's by tomorrow morning and frost is possible for the first time in many suburban locations. An area of low pressure with tropical characteristics will pull out of the Gulf of Mexico early this weekend and slide to our southeast by early Sunday. There is a very good chance that this system becomes a named tropical storm (Nestor) and it should throw some rain our way late Saturday night and Sunday. A strong frontal system is then destined to reach us by Tuesday night and it should result in more rainfall for the Mid-Atlantic region.

On the heels of yesterday’s soaking rainfall, an intense coastal low will continue to impact the region today with wind gusts of to 50 mph and scattered power outages are certainly on the table. In addition, today will turn out to be one of the coolest days so far this season with temperatures holding in the 50’s and with much lower wind chill values. The breeze will stick around tonight and Friday and then will die down on Friday night allowing for temperatures to fall to near 40 degrees in some suburban locations. Low pressure will pull out of the Gulf States this weekend and it could produce clouds and rain here later Sunday into Monday.

A vigorous upper-level low is dropping southeastward across the Great Lakes today and will interact with a powerful jet streak over the Tennessee Valley to help set off the formation of a strong coastal storm. This low will intensify this afternoon and tonight and will bring a soaking rainfall to the Mid-Atlantic region and the Northeast US – the likes of which haven’t been seen in many weeks. Winds will become an increasing problem as well and could gust past 50 mph later tonight and on Thursday in the Mid-Atlantic/NE US following the departure of the strong storm and possibly to hurricane force along coastal regions of southern New England. As some colder air wraps into the system on Thursday, there is a threat for a changeover to snow in some of the higher elevations of northern New York and New England.

A vigorous upper-level low will drop southeastward across the Great Lakes today and will help to set off the formation of a powerful coastal low along the Mid-Atlantic coastline. This low will bring a soaking rainfall to the NYC metro region today on the order of 2+ inches and the winds will become noticeable as the storm undergoes intensification. The storm will continue to intensify as it rides up along the Northeast US coastline later today into tonight bringing with it heavy rainfall, strong winds and ultimately, even a change to snow in some of the higher elevations of northern New York and New England. Following the storm, winds will be quite strong here on Thursday with gusts to 40 mph and temperatures will struggle to escape the 50's in many spots.

The weather will be nice for today's Yankees playoff game with Houston, but tomorrow night's game is in doubt as soaking rain is on the way. A vigorous upper-level low will drop southeastward across the Great Lakes on Wednesday and will help to set off the formation of a powerful coastal low along the east coast. This low will intensify on Wednesday and begin to impact the Mid-Atlantic region with significant rainfall – something that hasn’t been seen much in recent weeks. The storm will continue to intensify as it rides up along the Northeast US coastline late Wednesday into Wednesday night bringing with it heavy rainfall, strong winds and ultimately, even a change to snow in some of the higher elevations of New England. Following the storm, winds will be quite strong on Thursday in the Mid-Atlantic region and temperatures will struggle to escape the 50’s in many areas.

The big story of the week weather-wise is the likelihood for a significant rain event here on Wednesday - something we haven't seen much of in recent weeks. High pressure will build into the area for the next couple of days, but a frontal system will then approach the region at mid-week from our northwest. In addition, low pressure will pull out of the south-central states and head towards the Mid-Atlantic coastline and these two systems will combine into a powerful storm for the NE US. There will be periods of rain on Wednesday and some of it can be heavy at times with the total rainfall amounts likely increasing as one goes up along the DC-to-Philly-to-NYC-Boston corridor. Following the passage of the mid-week storm, it’ll turn quite cool and windy on Thursday with highs likely confined to the upper 50's.
