Blizzards. Arctic Outbreaks. Freezing Rain. Scraping your windshield. Getting stuck behind a conga line of plows on the highway. Common occurrences in winter, and you’ve been dealing with them for several months while dreaming of sunshine and warmer days. You can stop dreaming now, because those days have arrived. They may not last long though, so you’d better enjoy them while they are here.
High pressure will move offshore today, with southwesterly winds bringing warm air into the region today into Tuesday. If you live along the South Coast or especially the Cape, it won’t be quite as warm, as southwest winds will be a seabreeze coming off the still fairly cool ocean. Away from the South Coast, we’re looking at highs well into the 70s, with some places possibly getting into the 80s on Tuesday. Yes, we’re serious, April Fool’s Day was over a week ago. Wednesday is the tricky day. Low pressure will pass by to the north, dragging a cold front across the region, likely producing scattered showers and maybe some thunder. It will still be warm ahead of the front, though the cloud cover and showers will prevent it from getting as warm as Tuesday. However, if we can get some sunshine to develop, temperatures could get into the 70s one more time. We snap back to reality on Thursday as high pressure builds in with much more seasonable conditions lasting into Friday. We’ll start to warm up again for the weekend, but another system will approach from the west, with some more showers possible on Sunday.
We’re not quite ready to say that it’s OK to put away all of your winter gear just yet, this is New England after all, and we’ve had measurable snow into mid-May before. However, we’re getting close. One of the longer-range models shows the potential for at least some wet snow to mix in with some rain across parts of the region towards the middle of next week. That’s still a long ways off, and has plenty of time to change. This same model also shows the potential for the latter half of April to be very wet, which could result in a lot of flooding around here. We’ll worry about that later on though. For now, enjoy the warm weather.
