Doesn't feel like Fall
We have high pressure building in out of Canada Behind the cold front dropping south over southern New Jersey into Maryland and Delaware.
Radar shows some rain up around the Delmarva peninsula back into Virginia. Much of that over southern Maryland and southern Delaware is likely virga but there could be some scattered isolated showers here and there.
Satellite shows Mid level clouds from Imelda's circulation pushing in from the south Over the Middle Atlantic into Pennsylvania. North of there there's much more in the way of sun. Temperatures today will be above average. Tomorrow is going to be much the same Only a slight chance for some rain in the northern middle Atlantic.
Then on Wednesday as the high pressure overhead pushes north and east A weak and very moisture starved cold front will drop through. So not expecting much rain if anything out of it. The region will cool off a little bit for Wednesday into Friday. That northeast breeze is going to feel quite chilly As temperatures drop back to average to slightly below average For the time of year. Then the heat heads right back up for later Friday into next week, as High pressure starts drift east changing us to more in the way of a southern flow.
It still looks like the region should be mostly dry for Monday and Tuesday. Our next chance for more in the way of widespread rain showers won't be until late Tuesday or Wednesday of next week. I really don't expect any rain for the northern Middle Atlantic But I can't completely rule it out. Depending on what's going on with Imelda Maryland and Delaware possibly Southern New Jersey could see some rain associated with her. But any rain should be widely scattered. Southeast Massachusetts The Cape and Off-shore Islands could also see a little bit of rain for late Tuesday into Wednesday, This will have more to do with ocean effect rather than Imelda.
Tropical Storm Imelda and Hurricane Humberto

Humberto is still a major category 4 hurricane with maximum sustained winds of 145 mph, minimum central pressure of 940MB, currently tracking northwest at 13 mph. As he moves into cooler waters He should start to gradually weaken over the next couple of days
Imelda has maximum sustained winds of 60 mph, minimum central pressure of 988 MB tracking north at 9 mph. Imelda Is slowly enveloping over the Bahamas. The satellite image show she looks fairly impressive. As she is taking advantage of that marginally favorable environment.
We do have that weakening upper level low sitting over the Southeast US, As Imelda continues to organize and push further north.
That stalled front along the east coast Is going to protect the United States from both of these Systems. Keeping the majority of their impact out over the ocean. Humberto will be passing a few hundred miles west of Bermuda Later Tuesday and Wednesday This will keep most of his impacts out over the ocean but gusty winds and two to perhaps four inches of rain will be possible for the island.
Imelda is gonna stay well off the southeast coast most of her wind impact an excessive rain issues out over the ocean. Gusty winds of 35-40 mph will still be possible with winds of 20-30 mph north of that along the coast. A few days ago the Carolinas looked to be going to have an issue with excessive rain The possibility of a lot of flooding But with Imelda staying so far-off shore before she gets yanked east, the flooding brisk is no longer an issue. So that is very good news for the Southeast US.
The trough to the north Is going to exert influence on Humberto and pull him north and then northeast. At the same time with that weakened upper level low Humberto is going to latch on to Imelda and forced her to follow him. The East Coast's good news is not such good news for Bermuda, Over the next day or so Imelda is going to strengthen into a hurricane. This will make her the 9th hurricane so far of the season. Imelda Looks to To make a close pass or a direct impact on Bermuda Later Wednesday and Thursday likely as a category 1 hurricane but possibly a category 2

While the East Coast has no direct impact from these systems. High surf and dangerous rip currents will still be an issue along the coast.
