Weekly Outlook: April 13-19, 2020

We’ve got quite the storm coming in to start the week, but it’s not the only one that may impact us before the week is out.

Low pressure will head through the Great Lakes and into Ontario today, bringing some very adverse weather into the region. We’ll have periods of rain, possibly heavy at times throughout the day, with some thunderstorms possible as well. The biggest threat will be the wind. High Wind Warnings have been posted for nearly all of Southern New England, with Wind Advisories for southern portions of New Hampshire and Maine. Sustained southerly winds of 25-35 mph are likely, with gusts to 50 mph or more common, especially in southern New England. This would be enough to take down some trees and power lines, but it could end up being worse. Not far above the surface, winds will be screaming out of the south at 90-100 mph. We’ll have some relatively stable air below that, keeping those winds aloft from getting down to the surface for the most part. However, some of the heavier downpours, especially in thunderstorms, will help bring some of those strong winds down during the afternoon, which could result in wind gusts of 60-70 mph or more, especially across southeastern Massachusetts and Rhode Island.

A cold front moves through during the evening, bringing an end to the rain, and allowing winds to rapidly diminish at night as they shift into the west. High pressure then builds in for Tuesday with some sunshine, but it will remain breezy as Monday’s storm moves into northern Quebec. Clouds come right back in Tuesday night as low pressure rides along a front stalled out south of New England. It looks like this system will remain fairly far to the south, with the best chance for any shower activity across the South Coast, Cape Cod, and the Islands. Another weak disturbance may bring in a few showers on Thursday. High pressure then builds in for Friday and the weekend, but we’ll have to keep our eyes on a couple of systems that look like they’ll stay south of the region right now.

Monday: Windy with rain, heavy at times, possibly some thunderstorms. High 56-63.

Monday night: Rain ending in the evening, then becoming partly cloudy with diminishing winds. Low 37-44.

Tuesday: A mix of sun and clouds, breezy. High 51-58.

Tuesday night: Partly to mostly cloudy. Low 35-42.

Wednesday: Plenty of clouds with a few showers possible along the South Coast and across Cape Cod. High 45-52.

Thursday: More clouds than sunshine, breezy, slight chance for a few showers. High 43-50.

Friday: Sunshine and some afternoon clouds, breezy. High 45-52.

Saturday: Partly to mostly sunny. High 48-55.

Sunday: A mix of sun and clouds. High 52-59.
