Weekly Outlook: May 20-27, 2019

The time has finally arrived. We hereby declare it safe to put away your snowbrushes, shovels, winter clothing, etc. Winter has finally ended around here. We hope you enjoyed the 3 days of Spring we had this year, because we’re going right to summer now.

We get an early taste of summer today with warm and humid conditions. Many locations, especially away from the South Coast, could top 80 degrees this afternoon. However, with a cold front approaching this afternoon, we’ll have to contend with some showers and thunderstorms. Some of the storms could be quite strong to severe, especially north and west of Boston, up into southern New Hampshire and across central and western Massachusetts. Some of the stronger storms may produce torrential downpours, strong winds, hail, and frequent lightning.

Once the front moves through, cooler and drier weather settles in for Tuesday on gusty winds. A pop-up shower or two can’t be ruled out as well. High pressure builds in for Wednesday with temperatures moderating back to seasonably mild levels.

The end of the week looks mild, but unsettled. We have a system moves through on Thursday, producing some showers across the region, mainly during the afternoon and at night. High pressure builds in with cooler and drier weather again for Friday and at least part of Saturday before another system approaches, with another round of showers likely later Saturday into Sunday. Neither of these systems look strong, and the timing is still a bit uncertain, so don’t go cancelling any outdoor plans for the weekend just yet. Yet another system may approach for Memorial Day, but for now at least, most of the day looks dry, with any shower activity likely holding off until evening or at night.

Meanwhile, in the Atlantic, the tropics look like they are starting to wake up a little. Hurricane season in the Atlantic officially starts on June 1, but it’s not unheard of for tropical systems to develop before then. As of early Monday morning, a disorganized area of showers and thunderstorms was located between the Bahamas and Bermuda. This area could become more organized over the next 12-24 hours, and could become a tropical or subtropical cyclone later today or Tuesday. While it is expected to remain weak, and should get absorbed by a cold front towards midweek, it could bring some showers and squally conditions to Bermuda. It’s not a threat to us here in New England, but it should serve as a reminder that hurricane season is nearly here and we are WAAAAAAAAAY overdue for a hurricane to impact us. The last one to make landfall in New England was Hurricane Bob in August of 1991.
