Welcome to the last day of September.

We have that trough dropping in out of Canada with the cold front over New York State and New England dropping through the region. Radar and satellite show the clouds streaming in from Imelda Into the northern Middle Atlantic and Pennsylvania. With the clouds over Maryland Delaware into southern New Jersey There is a chance for some light rain or drizzle, but it shouldn't be too bad. North and west of there should be dry today.

North of the cold front It's mostly sunny, with temperature starting to cool off. South of the front It is warmer with muggy conditions in the Middle Atlantic. As the cold front continues to drop south it is going to take these warmer temperatures and muggy conditions out of here.

Hurricanes Humberto and Imelda.

Humberto has maximum sustained winds of 80 mph, minimum central pressure Of 979 mb, he is moving north northwest at 17 mph . As he's interacting with that trough dropping down out of Canada, that we can see on the satellite is shredding him apart. Imelda also has maximum sustained winds of 80 mph, Central pressure of 980 MB. With the weakened upper level low to her west; she's starting to feel Humberto 's tug and is tracking northeast at 7 mph

The  two hurricanes Together That their respective circulations Are impacting each other With windshield. With the trough dropping out of Canada The added windshield has exposed Humberto's center. Humberto will likely be downgraded to a tropical storm at some point today.  He is going to stay several hundred miles west and then north of Bermuda, so no direct impact there. Imelda Is going to be right in his way wake, straight for Bermuda. Imelda Is going to be aided by the wind Sheer caused by the trough and slightly strengthen s she as she gets close to Bermuda So it's possible she could bring category 2 hurricane conditions to the island. Regardless of how strong she is. Imelda is going to bring powerful winds and dangerous storm surge to the island  late tomorrow into Thursday.  She will be moving quickly so conditions should quickly start to improve later Thursday as she is passing to the east.

back to the Northeast

For the Northeast as the trough that is protecting us from the hurricanes moves in We are going to cool off to average to below average temperatures for a couple of days. But the high pressure Is going to ensure that we stay dry. On Friday the high pressure is going to start to slide towards the coast We will start to see more in the way of a southerly flow that is going to start to warm us up for Friday.  As the high pressure Continues to slowly slide east Saturday and Sunday  we'll see temperatures continuing to warm and become above average. The entire weekend looks to be dry. Monday will be a mirror image of what we saw over the weekend with above average temperatures and dry conditions. Then on Tuesday into Wednesday We will have a weak moisture starve cold front approach and slide through the region bringing back the chance for more in the way of widespread but scattered showers to the region.

Even though we're going to be in October. As we start to think about Halloween we're still going to have quite a bit of warmer temperatures at times during the month.
