A few weak storm systems staggered over several days will prevent a major snowfall from unfolding in the East this week, but wet weather will allow minor travel problems to unfold.
The three smaller storms are likely to remain separate, rather than combine forces into one large, very disruptive storm.
Through Tuesday, a fast-moving storm will cause rain to spread northeastward from the Gulf Coast to New England. Since there is no real cold air available to this storm until the last minute, most of the precipitation that falls will be in the form of rain.
Enough rain and poor visibility will occur to cause some travel delays. Ceilings could become low enough in the coastal mid-Atlantic and New England to cause minor delays at area airports for a time on Tuesday.
During Tuesday into Wednesday, a storm from western Canada, known as an Alberta Clipper, will spread a swath of mostly light snow from the northern Plains to the Great Lakes and Appalachians.
Colder air accompanying this storm will cause enough snow to make roads slippery and potentially lead to deicing delays at airports mainly in the Upper Midwest.
The air will still not be cold enough to support snow in the I-95 Northeast during the day Wednesday from the clipper storm. However, once again, minor travel disruptions are possible due to spotty rain in the afternoon.
During Wednesday night into Thursday, a third storm system will swing quickly eastward across the South and offshore. While this storm will turn northward, odds are it will stay too far offshore to bring a major snowstorm.
Most likely the bulk of the third storm will stay offshore, but spotty snow could fall farther west over land.
By Wednesday night, the air would be cold enough for snow or a rain/snow mix in the coastal Northeast. Only if this third storm were to strengthen quickly would it throw a period of heavy snow back across the I-95 Northeast. This is not likely.
On the other hand, enough moisture may be hanging around to produce spotty light snow during this time. As a result, it bears watching for possible travel delays Wednesday night in the mid-Atlantic and Thursday morning in New England.
Through the weekend and into next week, colder air will continue to push southeastward in stages, but it will stop well short of the magnitude of the cold air from early last week.
Yet another storm is being watched for development near the coast. This storm has a chance at bringing significant snow to parts of New England and neighboring Canada on Saturday. A period of snow is possible in parts of the mid-Atlantic Friday night.
A tropical wave is likely to become the Atlantic Basin's next tropical storm as it approaches or crosses the Caribbean Sea later this week.
Bouts of wet weather will soak the northeastern United States during the last full week of September.
Typhoon Megi will threaten lives and property across Taiwan and eastern China into the middle of the week.
Gusty winds will accompany a push of chilly air across the Great Lakes through Tuesday.
The final day of September will bring a rare lunar event that hasn’t occurred since March of 2014, a Black Moon.
Following some rain and gusty winds on Tuesday, a strong storm will target the United Kingdom on Thursday.
