Significant Weather Weekly Outlook (Updated)
Hazardous weather is unlikely through early next week in southern New England. The purpose of this message is to just refresh the overview through this weekend.
A closed upper trough will move slowly across the Northeast through Friday. That combined with a very slow-moving occluded front and offshore surface low pressure area will result in periods of rain or showers through tonight and probably into Friday. The heaviest rain is expected to fall this afternoon and this evening as that frontal boundary moves slowly east. Clouds, cool temperatures, and scattered showers or drizzle will likely linger overnight into Friday.
A significant pattern change is in store for the weekend as the upper low pressure moves offshore and a broad ridge of high pressure builds into southern New England. Warmer temperatures will prevail this weekend. High temperatures will reach the 70s to around 80 Saturday and 75 to 85 degrees on Sunday across most of southern New England. Onshore sea breezes along the south coast, including the Cape and Islands, will result in somewhat cooler temperatures there. The weekend looks to be mostly dry, although there is a slight risk of a weak and fast-moving upper-level disturbance producing a few showers Saturday night or Sunday. However, confidence is low at this time of any showers actually materializing in our area this weekend. Either way, hazardous weather is not expected through the weekend and into early next week.
