Wet weekend on tap:
The
mesoscale predictability of where the heaviest convective rainfall
axis will be is still low at this time, but potential exists
somewhere across Central CT/Central LI westward into Lower HUD/NE
NJ/NYC metro. In this region, threat for locally torrential rain and
localized swaths of flash flooding exist late tonight into Saturday
afternoon, with shortwave lift encountering increasingly deep
moisture of 1-2 +std PWATs, apparent instability gradient, and a
focus for development/SW-NE training along a stalling frontal
boundary.
