Forecast discussion: Despite sunshine today, a low pressure system over the Canadian Maritimes continues to influence our weather. As a high pressure ridge tries to build over New England, the low pressure system’s pressure gradient remains over New England. This fight between the two pressure systems have tightened the pressure gradient, hence the stronger afternoon winds. Both Logan Airport and T.F. Green Airport in Warwick, RI are showing winds of 20 mph with gusts of 30 mph as of 4 p.m.
As we head into this evening, the low will continue to move away from the area, allowing the pressure gradient to relax. This means the winds will diminish, and with the skies mostly clear, temperatures will fall into the lower 30’s. We will return to sunshine on Saturday, but temperatures will be about 10 degrees cooler. A weak cold front will pass over Southern New England Saturday night, and may trigger some showers during the morning hours. Because the front is mostly dry, we will have dry conditions the rest of Sunday, but we will keep mostly cloudy skies until Sunday night.
We will begin Monday with mostly sunny skies and temperatures into the lower 50’s. A weak warm front will help raise our temperatures Monday night into the lower 40’s. Veteran’s Day looks nice for any outdoor events, but a weak cold front will pass through early Wednesday morning. We will see some isolated showers during the morning, before breaks of sunshine come out for the afternoon.
As we head into Thursday, the computer models have been agreeing that the polar vortex that is bringing well below normal temperatures to the Central U.S. and Midwest will move over New England. We will feel that cold air as temperatures only reach the lower 40’s. The American model is also trying to form a weak low over the Delmarva Peninsula Thursday evening. This system will try to move northward, and may bring some scattered rain and possible snow showers next Friday into Friday night. The cold pool of air will remain over us into next weekend.
