Persistent rounds of rain return to eastern US for second half of week

The second full week of May will start off on a much drier note across the Northeast. However, this dry spell will be short-lived, with a wetter pattern returning by the end of the week.

For many cities across the region, the amount of rain that has fallen in the past week is greater than the amount of rain that fell during the entire month of April.

This complete 180 from abnormally dry weather to above-normal rainfall has been good for vegetation and helping with soil moisture and stabilizing the unusually low levels on streams and rivers. There are still pockets from Pennsylvania and New Jersey to Maine, where soil moisture remains below the historical average (1916-2004) for early May.

Replenishing the soil moisture this spring could be an important factor to avoiding significant drought during the summer, with hotter and drier weather in the forecast.

While the rain is good for helping ease drought conditions, it can be a nuisance to those who live in the East.

A moisture-laden storm is expected to traverse very slowly across the eastern third of the country starting on Thursday and continuing into the weekend.

"Residents along the Eastern Seaboard will be hard-pressed to find more than a couple days in a row of completely dry weather over the next week or two," said AccuWeather Meteorologist Bill Deger.

Rain boots, umbrellas and rain coats will be necessary items to have on hand for the latter part of the week, through the weekend and even into next week.

Rounds of showers and thunderstorms will plague this area through at least mid-May, Deger added.

These rounds of rain and storms will be the result of an unsettled weather pattern that develops over the region.

"Rainfall amounts of an inch or so could fall from Boston to Philadelphia next Friday and Saturday," said AccuWeather Senior Meteorologist, Dan Pydynowski.

"While this is not enough rain to cause any flooding issues, the rain could still come down heavily at times and cause standing water on roadways in low-lying or poor drainage areas, " said Pydynowski.

Warm, springlike temperatures combined with the moisture from this pattern will trigger some thunderstorms, especially south of the Mason-Dixon Line.

Dangerous lightning, gusty winds and hail could be threats from those storms.
