Fine Weather Follows the Northeast Rain

Tuesday 11 a.m.

Here is a video I prepared at 6:30 this morning. Since then, the worst rains have shifted toward coastal New Jersey. Earlier, Philadelphia's western suburbs got 2-4 inches of rain, turning roads into rivers, streets into streams and parking lots into ponds.

With more than 2 inches of rain in Philadelphia, the rainfall total since June 1 is now above 27 inches, which is about three times the average rainfall for the same period. So far this year, there has been more than 40 inches of rain, which is close to the average total for the entire year. There has also been more rain so far this year than all of last year.

This map shows the pressure pattern early this morning. The most intense rainfall was associated with the low pressure area over Delaware. The system also spawned damaging thunderstorm winds as it tracked from Delaware across southern New Jersey.

At first, the heaviest rain was in Philadelphia's western suburbs. This radar map shows the boundary between where it was pouring and where it was doing nothing.

As the low pressure area moved northeast, the heavy rain swept eastward across southern New Jersey.
