That’s right… nor’easter. But in September, that means rain… not snow. In the wake of Hurricane Lee, a trough will dig into the eastern US, and a coastal low pressure will develop over North Carolina Sunday night. That low pressure will race northeast as shown in the first image. That low pressure will push NE on Monday, and keep the Northeast US unsettled with periods of rain.
For the Hudson Valley, this means clouds increasing on Sunday, with highs in the mid 70s. We’ll likely have a nice day on Sunday, before skies become overcast Sunday evening. A batch of rain showers is likely to push into the valley between 8pm and midnight Sunday evening. That batch of showers moves east before sunrise on Monday… likely leaving the Hudson Valley cloudy with patchy areas of showers and drizzle for Monday. We’ll need to monitor the development of the nor’easter. Computer guidance is mixed with how much rain we see in the Hudson Valley on Monday. Most guidance keeps the steady rain to our east on Monday, but a few areas of rain could creep into the Hudson Valley on Monday. So expect rain showers Sunday evening, and the threat of showers to persist through the day on Monday.
Projected rainfall is shown on our 3rd image. You can see the Hudson Valley projecting between 0.50″ and 1.50″ of rain… with the highest totals further east, based on the track of the coastal storm (nor’easter). Conditions should improve again on Tuesday… but until then, more unsettled weather for the Hudson Valley. Updates will be shared as needed. Have a great Sunday!
