Woke up to the strange sound of something hitting against the window and lo and behold yes it was rain! The first round of downpours with the cold front moved through and there is more to go as the wave develops this afternoon and tonight and brings with it a pretty good shot of widespread rain on the order of 1 to 2 inches. Some places have gotten over an inch of rain just from the first shot of downpours so if you get at least the same with the next round you got your 2 inches. Check the latest radars on this page and you can see the moisture beginning to take shape to the southwest. This will be the area that moves in later today. We also will not get out of the 70s today for the first time in 2 months. New York City has seen 80 degrees everyday for the last 60 days or more in a row. That streak will end today.
This is the latest weather service rainfall map for the NYC NE NJ Long Island, Southern Connecticut and Hudson Valley and below is the gfs model run. Pretty much the same idea here all the way around. 1 to 2 inch rains go all the way back to Eastern Pennsylvania and cover all of southern New England.
This moves out late tonight and we should spend Friday slowly improving but then more rain is coming. In fact the look is a little more interesting over the weekend as this strong upper trough swings through and takes its time getting through. This might mean some rain as early as Saturday morning into early Sunday morning and then another round of rain later Sunday into Sunday night as as second wave develops. This is happening alot faster as I thought at first there would be one shot Saturday night into Sunday morning.
I was actually quiet surprised at this as it supports the notion of 2 more waves. The upside is that if it happens it is a rain that is essentially spread out over the course of the weekend which allows it to soak in..which is also the bad news in that it messes up the whole weekend! It all moves out early Monday morning and then get set for another warm up as we move into next week.
