Heavy Rain, Thunderstorms Take Aim at New England Next Two Days

Two waves of rainfall followed by a line of thunderstorms will be making its way through New England starting tomorrow afternoon and continuing through Saturday evening. Here's a breakdown on impact and timing.


FRIDAY AFTERNOON


the first batch of precipitation will break out Friday afternoon from west to east. This batch of rain will be steady to at times heavy, especially across southern New England. Higher elevations of northern New England will begin as snow with lower elevations perhaps seeing a rain/snow mix. This will switch over to rain quickly Friday evening. Before the switch over, the Green and White Mountains could see a quick inch or two of snow. This will get washed away quickly.





FRIDAY NIGHT


The bulk of rain will continue working through New England during the evening hours. By the end of the evening, the heaviest of rain will be gone, but showers will linger around for much of the night. A widespread quarter to half an inch of rain is expected in this batch. Areas of dense fog could develop overnight across northern Massachusetts, southern New Hampshire and southern Vermont.


SATURDAY MORNING-MIDDAY


A strong area of low pressure will move well north of New England and, in doing so, will lift a warm front through the region. Temperatures will soar into the 50s and 60s across much of New England. Rain will once again be steady and at times heavy with this second batch. The heaviest of rain looks to fall throughout the morning hours. Higher elevations could once again see some snow and mixing early, but everywhere will switch to rain by midday, even the summit of Mt. Washington will see plain rain.


SATURDAY AFTERNOON-EVENING


New England will very likely work into a dry slot on Saturday afternoon. During this time, rain will not be as widespread or as heavy, but there will still likely be plenty of showers around, so this "dry" slot will not be fully dry for everyone. While some areas of Vermont and potentially New Hampshire could actually see some breaks of sun Saturday afternoon, it will remain cloudy and damp for a majority of the region.


As the low pulls away from the region, it will drag a rather potent cold front across the region. This front will swing into New England from New York and will rapidly push through the region from Saturday mid-afternoon through Saturday evening. This front will produce more showers and potentially some thunderstorms. Thunderstorm chances will be greatest in Vermont and northern New Hampshire. The chances for thunderstorms decrease more and more the further south and east you get in New England.


In Vermont, there is a slight chance of potentially strong thunderstorms and brief periods of high winds as the front pushes through. While thunderstorms become unlikely south and east of Lake Winnipesaukee, the front will produce more rain showers in the late afternoon and evening.





SATURDAY NIGHT-SUNDAY


This potent cold front will create a much cooler Saturday night than Friday night. There will be a lot of sun for most of the region on Sunday, but it will be quite chilly and breezy. This chill will not last long as seasonable weather returns for Monday.
