The rain just keeps coming in the East since the last part of summer. Anyone for 3 feet of rain?

The rain has not quit in the East in the wakes of Irene and Lee.

Most recently a nearly stationary low pressure area over the Midwest has been working to funnel moisture up from the Gulf of Mexico and in from the Atlantic Ocean, producing rounds of heavy rainfall.

As of last week, several cities, including Philadelphia, New York City, Allentown and Baltimore, have had record rainfall for two consecutive months.


This graphic shows rainfall since Aug. 1, 2011, as of 2:00 a.m. EDT on Thursday, Sept. 29, 2011.

Philadelphia and New York City are within reach of surpassing 30 inches of rain for the two-month period ending Sept. 30. Additional rain will fall on these cities and others through the end of the month.

Many locations have the potential to reach or exceed 2 feet of rain for the two-month period, including Harrisburg, Lancaster, Mount Pocono, Reading, Scranton, Selinsgove and York in Pennsylvania, Binghamton, N.Y., Wilmington, Del. and Trenton and Wrightstown in New Jersey.

Locations already topping the 2-foot rainfall barrier for August and September thus far include Middletown, Pa., Newark, N.J., and Montgomery, N.Y. These areas have received 25.26, 25.45 and 25.13 inches respectively as of the midday hours Wednesday.

To put the rainfall in perspective, most locations in the region typically receive between 4.00 and 4.50 inches of rain each month during August and September. The normal annual rainfall for most locations in the region is between 40 and 50 inches.

As we have said before so many times in recent weeks, "More rain is on the way!"

Unfortunately, not all of the additional rain through the end of the month will come at a gradual pace.

The rain will be heavy enough in localized areas to cause flash, urban and small stream flooding.

The ongoing rainfall will hinder normal seasonal maintenance, flood cleanup and repair work in the wake of the earthquake in August.

There is at least some good news for leaf-peepers and skiing interests in Vermont, according to AccuWeather.com's Grace Muller. Crews in the Green Mountain State have roads on the mend.
