High pressure will build into the Mid-Atlantic for the next couple of days and we’ll start off the new work week with cool and rain-free conditions. A strong cold front will slowly trek across the nation over the next few days and it’ll arrive in the Great Lakes region by Thursday. As a result, Halloween Day (Thursday) around here may feature showers ahead of the cold front with breezy and mild conditions and heavy rain is possible late Thursday night into early Friday as the front arrives. Following the passage of the front at the end of the work week, cooler-than-normal air will push in for the upcoming weekend and it looks like the pattern may stay on the cool side as we progress through the first part of November.

High pressure will remain in control of the weather around here into the weekend, but a couple of fronts will bring us some rainfall from later tomorrow into Sunday. Tropical moisture from the Gulf of Mexico will merge with an eastward moving cold front over the next couple of days and produce significant rainfall from the northern Gulf to the Ohio Valley. As low pressure pulls to our northwest along the cold frontal boundary zone, a warm front will push northward later in the day on Saturday. This front could bring some scattered shower activity to the region late tomorrow and tomorrow night and then the cold front will close in from west-to-east during the day on Sunday with occasional rain likely and it can be heavy at times. The low pressure will push off the coast on Sunday night paving the way for drier conditions as we begin the new work week.

High pressure will remain in control of the weather around here for the next couple of days with generally cool and dry conditions in the Mid-Atlantic region. There will be an increasing chance for rain this weekend as low pressure pushes out of the Deep South and heads toward the Ohio Valley/Great Lakes. As a result, a warm front will push northward into the Mid-Atlantic region later Saturday and the low pressure system will push a cold front in our direction on Sunday. Rain is likely to accompany both frontal systems from later Saturday into Sunday with the heaviest amounts likely to come on Sunday. The low pressure system will push off the Mid-Atlantic coastline on Sunday night and drier air will return for the early part of next week.

The World Series between the Washington Nationals and Houston Astros began last night in Houston, Texas, but weather was not a factor. The Astros stadium known as Minute Maid Park has a retractable roof and it was closed last night for Game 1 which was won by the Nationals with a 5-4 score. The World Series will shift to Washington, D.C. on Friday night for Game 3 and then Games 4 and 5 (if necessary) are scheduled for Saturday night and Sunday night respectively.
From this vantage point, it appears the weather will be decent for Game 3 on Friday night with cool and dry conditions, but then rain could become a factor this weekend for Games 4 and/or 5. It does not appear that any of these three scheduled games in Washington, D.C. will be played under truly cold conditions as any significant cold air outbreak for the Mid-Atlantic region should hold off until later next week – perhaps in time for Halloween Day. Weather has indeed had a big impact on some World Series games in recent history in terms of both cold and precipitation.

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 near 40 degrees for late night lows - upper 30's in some outlying spots. 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 40-50 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 into the upper 30’s 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.
