Desert Like Dry
Posted by Chris Lambert
Yikes! At one point this afternoon, the relative humidity in Boston was 14%. The same as Las Vegas, NV and near the 13% in Tucson, AZ. Combine that with a gusty wind, and the brush fire risk was high.
Tomorrow is another dry day, and with a strong breeze and afternoon humidity down in the 20-30% range, brush fires can easily start and spread again. Although many of us are anxious to get out there and get the yard all cleaned up after a long winter, it's not a good time to burn off the dead brush and leaf piles as the wind can pick up some of those embers and spread that fire quickly. Also, be careful discarding cigarette butts.
At least those winds turn to the south tomorrow, and that'll bring in milder temperatures as highs head toward 60 away from the coast. It'll remain cooler down through the Cape and Islands.
Opening day looks dry as well, as temps near 60. We'll watch the likelihood of winds turning onshore in the afternoon, and that'll drop temps back through the 50s late in the afternoon close to the coastline, including at Fenway park.
The middle part of next week presents a challenge temperature-wise a cold front drops in from our north Tuesday night/Wednesday AM. On the other side of that front, winds turn north to northeast and that squashes any sort of warm weather this time of year. Occasional showers ride along that front as well mid to late week, but most look to miss us just to our south. Just south of the front, temperatures are in the 70s. If we can get a day or two with that front moving back north of us, we'll do ok, but the problem is, that's a tall order this time of year with an area of high pressure to the north. As of now, my 7-day forecast is based on the fact that the warm air stays just south of us Wednesday-Friday, putting us generally in the 50s.
