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.

Low pressure continues to spin off the Mid-Atlantic coastline, but most of its impact will remain to our east. A west-to-east moving cold front will arrive late Saturday and finally help to push the western Atlantic low pressure system farther out to sea. A weak disturbance could throw some clouds and showers our way later Sunday or on Sunday night. The overall pattern will remain on the cool side going through the early and middle parts of next week.

Low pressure will continue to strengthen off the Mid-Atlantic coastline today and it’ll generate windy, damp and cool conditions around here with occasional showers. A west-to-east moving cold front will arrive late Saturday and finally help to push the western Atlantic low pressure system farther out to sea. The frontal passage will also maintain an overall relatively cool weather pattern here through the early and middle parts of next week.

A very active weather pattern across North America will bring a tremendous early season shot of cold air and accumulating snow to the region from the Rockies to the Northern Plains over the next few days and two systems off the east coast will merge into one powerful storm just off the Mid-Atlantic/NE US coastlines. The cold front that passed through the Mid-Atlantic region earlier this week has stalled out over the western Atlantic and low pressure has formed along its boundary zone. Another low pressure system has formed a few hundred miles off the South Carolina coastline and is already producing winds near tropical storm strength. Ultimately, this second system is likely to merge with the “frontal boundary zone” low pressure system just to its north and form one powerful storm. A west-to-east moving cold front will arrive late Saturday and finally help to push the Atlantic low pressure system farther out to sea. It will also maintain an overall relatively cool weather pattern through the early and middle parts of next week.
