Rich tropical moisture remained across the Northeast region. Precipitable water values continued to be high at 1.90 to 2.00 inches. Morning soundings showed very little upper level flow. A static atmosphere prompted a risk for flooding; storms that developed tended to move very little. Isolated wet microbursts were a potential due to CAPE values over 2000 J/kg. Storms developed from outflow boundaries and light convergence aloft.
