Flash FLood Watch Continues Overnight Into Tuesday Morning Improving Weather Wednesday
The severe weather we experienced this evening was probably one of the most active rounds of severe weather I have ever witnessed here from Eastern Pennsylvania to Southern New England. At one point all of New Jersey was under either a severe thunderstorm warning, a flash flood warning, or both. Much of our zone was hit very hard with thunderstorms of varying intensities. The first wave of low pressure has gone by. Now a second wave of downpours will move through overnight into Tuesday morning. With the ground already saturated flash flooding will occur fast in some heavier downpours that will arrive during the early morning hours and last into midday Tuesday.
SATELLITE
REGIONAL RADAR
The regional radar shows the first round of severe weather to the northeast while a second area of heavy rains and possible thunderstorms revs up to the south west. This is a second wave of low pressure that has to move through in order for the frontal boundary to push offshore. This should start to happen during Tuesday. Downpours should come to an end around midday from west to east; sooner toward Pennsylvania and later east of New Jersey and NYC. Temperatures Tuesday won’t get much above the low to mid 70s.
LOCAL RADAR NEW YORK CITY
LOCAL RADAR PHILADELPHIA
Rainfall amounts will reach 3 inches or more in some areas making for additional flooding in vulnerable urban areas as well as areas near small streams and rivers. Once the frontal boundary moves far enough to the east Tuesday we should dry out Tuesday night. Wednesday look for sunshine to return with highs in the upper 70s and lower 80s. Sunshine warm and reasonably humid weather is forecast for Thursday and Friday with highs both days in the 80s.
