The atmosphere has a distinct Florida feel to it this afternoon and we are seeing a some convective activity developing but it seems to be confined mainly to coastal areas along a sea breeze boundary that tends to develop in situations like this. We are seeing a few pop ups in some of the New Jersey coastal counties particularly from Ocean County southward. Also Long Island and coastal Connecticut are getting into the game of slow moving heavy downpours with some local flash flood warnings begin posted. This is all to typical when you have a developing upper low and trough to the west and it is of course a feature that doesn’t look to be in any rush to get out of the way. Throw in some daytime heating and instability and you get boomers with heavy rains.
The good news so far judging from all the radar activity today is that much of New Jersey and the Hudson Valley are getting a well deserved break from the big rains and flash floods of yesterday. We might see a few scattered cells develop between now and 8pm but it should be widespread activity.
LOCAL RADAR NEW YORK CITY
Looking ahead to Monday it has been my contention since Thursday that this was the day to be most concerned about with the upper low at full strength and to our west and some solid dynamics to produce flash flooding again. Models remain essentially useless in situations like this so just remember that much like Saturday, the risk is there for heavy rains and flash flooding for somebody. Also I wouldn’t be surprised if one or two thunderstorms grow to severe levels. Keep and eye on the sky and the radar.
Tuesday will be a repeat performance but it should be the last day of any widespread activity as the upper trough finally pulls out Tuesday night. Wednesday and Thursday look to be very warm humid days but with only some isolated downpours and thunderstorms. Then it picks up again Friday into Saturday.
