Clouds Increase…Rain Develops This Afternoon

Low pressure lifting northward through the Ohio Valley today and into the Great Lakes tonight will drag a series of frontal boundaries across New England over the next 24 to 36 hours.

Initially, a warm front will advance northward toward the area today, passing over our region tonight and lifting into Northern New England on Wednesday. All the while, the storm center’s accompanying cold front will push eastward from the Ohio Valley and pass across the Northeast and New England during the day on Wednesday – shifting east of Cape Cod during Wednesday afternoon and evening.

Both of these two frontal zones will bring a period of wet weather to the area…with a more concentrated period of rain focused around the approaching warm front later today and tonight. Expect clouds to fill the sky this morning and for rain to develop over the area during the mid to late afternoon hours…continuing through the evening before eventually tapering to drizzle near or a bit after midnight. While most of the rain will be on the steady but light side of things…a few late evening downpours could pass over a couple of spots.

Behind tonight’s wet weather, winds will shift to the south and southwest and a surge of mild air will lift into the region. Temperatures will climb through the 40s overnight and likely reach into the lower 50s by morning across most of the Cape as we sit squarely in the storm’s warm sector, waiting the arrival of the aforementioned cold front.

The cold front will approach our area during the second half of Wednesday, bringing a renewed threat for some showers…but most of that activity will be fairly short-lived as compared to it’s Tuesday evening predecessor.

One additional thing to note…within the warm sector, strong southwest winds will develop Wednesday and continue throughout the day. A few wind gusts over 40 mph are likely and it’s possible that a couple of spots record a gust closer to 50 mph…particularly on the Mid and Upper Cape where temperatures will get noticeably warmer during the daylight hours.
