**More rain is on the way for the Mid-Atlantic region...wetter pattern brings two rain events continuing to alleviate any remaining drought conditions in the area**

One low pressure system will head up the Ohio Valley and a second will form by early tomorrow near the Mid-Atlantic coastline. The result here will be a cool, breezy mid-week with periods of rain that will continue to alleviate any remaining drought conditions in the Mid-Atlantic region. Another round of rain is likely from late Friday into Saturday from yet another low pressure system headed towards the east coast. Map courtesy NOAA, tropicaltidbits.com
Overview
Recent rain events in the Mid-Atlantic region have helped to alleviate drought conditions that began to develop last fall and more beneficial rainfall is on the way with two storm systems. Clouds will lower and thicken today as high pressure shifts off to the east of here and low pressure pushes into the Ohio Valley. A new low pressure system will form by early tomorrow near the Mid-Atlantic coastline and it will produce periods of rain for the mid-week and quite cool conditions as a low-level ocean flow of air forms in the DC-to-Philly-to-NYC corridor. In fact, temperatures may end up being some twenty degrees below-normal on Wednesday with the influence of the still chilly western Atlantic Ocean. A cold front then pushes through the region on Thursday night with a few showers and stalls in the area on Friday. Another low pressure system will likely ride up along that stalled-out boundary zone potentially bringing another round of soaking and beneficial rainfall to the Mid-Atlantic region from late Friday into Saturday.
Another rain event is headed to the Mid-Atlantic region and it can result in anywhere from a half an inch to one and a half inches helping to keep it nice and green around here as we transition into the month of June. A second beneficial rainfall is likely to take place from late Friday into Saturday as another low pressure system heads towards the east coast. Map courtesy NOAA, tropicaltidbits.com
Details
The overall weather pattern in the Mid-Atlantic region during the past several weeks has been one with occasional rainfall events in the Mid-Atlantic region allowing for a “chipping away” at drought conditions that began to develop last fall which featured some very dry stretches of weather (e.g., virtually no rain at all during October 2024 for the Philly metro area). This wetter pattern will continue through the remainder of May with one and quite likely two more soaking rain events...each of which can result in a half to one and a half inches of rain keeping it nice and green around here as we transition into the month of June. Looking ahead, there are signs of a warmer and drier pattern in early June so any rain this last week of May may be much appreciated in coming days.

High pressure shifts to the east today and opens the door for low pressure to climb up the Ohio River Valley during the next 12-24 hours or so. At the same time, a secondary low pressure system will begin to form near the Mid-Atlantic coastline and this system will be in the right location to usher in cool, ocean air on Wednesday into the DC-to-Philly-to-NYC corridor. In fact, temperatures could end up being some twenty degrees below-normal for this time of year all along the I-95 corridor (normal highs are now in the mid-to-upper 70’s). The rain should begin this afternoon in the DC metro region, during the overnight hours in Philly, and then by early-to-mid-day on Wednesday across the NYC metro and it’ll continue through Wednesday night in most locations to go along with those very cool and breezy conditions.

A cold front will push across the region on Thursday night and the then stall in the area on Friday. Its arrival on Thursday night can spark some shower activity in the Mid-Atlantic region and perhaps a thunderstorm or two. At this point, low pressure is likely to form along the stalled-out frontal boundary zone and this can result in a second soaking rain event from later Friday into Saturday with continued below-normal temperatures. After that, signs point to a drier and warmer pattern as we begin the month of June suggesting that any rainfall we can squeeze out during the remaining days of May may indeed be quite fortunate.
