After a hot summer day on Sunday, we’ll start the work week off with another warm, summer day. A mix of clouds and sunshine, along with highs in the low to mid 80s… with heat index values in the mid 80s as well. The story then turns to yet another wave of low pressure approaching the Hudson Valley and northeast.

A wave of low pressure will slide across the Ohio Valley on Monday, and spread scattered rain showers into the Hudson Valley by midnight on Monday night. Then as we head into the overnight, some areas of heavier rain are possible to develop. Periods of rain are possible into the morning commute on Tuesday before fully tapering off. Much of the computer guidance suggests that around an inch of rain is expected on average across the Hudson Valley (locally 0.75″ to 1.25″).

But the HRRR model is quite bold about the rainfall rates before sunrise on Tuesday.

The futurecast radar for 4am suggests that an area of torrential rains will push through parts of the Hudson Valley. If that solution is correct… then the region could see closer to 2″ or 2.5″ of rain… which could lead to flash flooding concerns. Something we’ll watch as we get closer to Monday night.
The Tuesday AM commute could be impacted with rain lingering until after sunrise, so be sure to plan for that as well. Have a great start to your work week, and we’ll update if flash flood concerns become more likely.
