Forecast discussion: Well, sunshine in the early morning quickly gave way to mostly cloudy skies in Boston. Despite the clouds, strong southwest winds helped raise the mercury to 90 degrees in the capital city today. Now, we are awaiting a cold front passing into eastern New York at the moment. A strong line of thunderstorms are moving through Hartford, CT as of writing this article. This activity will arrive over eastern Massachusetts within the next two to three hours.
So, some areas may see periods of heavy rain, with some areas seeing thunderstorms. These thunderstorms may be strong enough to create small hail, lightning, and gusty winds. The thunderstorms will dissipate as we lose the daytime heating from the sun. Precipitation will continue into the early part of the morning commute, so please take precaution for some poor drainage on roads and highways.
By mid-morning on Friday, we will have sunshine return to us, as a strong high pressure system brings a ridge over New England. This ridge will bring less humidity as well, so it will feel a little more comfortable to be outside. However, temperatures are not going down at all, as we have a chance to reach 90 degrees in the capital city. If the mercury can reach 90, Boston will officially have its first heat wave of the summer, as the last 2 days have seen high temperatures of 90 or more degrees. This nice weather persists into early Saturday night.
A weak disturbance will pass through New England Saturday night, and it may help trigger a passing shower or thunderstorm. The American model has been quite consistent with this scenario, although the European model keeps flip-flopping. Due to the consistency of the American model, I will keep the chance for precipitation in the forecast. Any precipitation would end by early Sunday morning, with mostly sunny skies by the late morning.
Another quick disturbance leaves us with a small window of time for any more precipitation early Monday morning. We will return to partly sunny skies and very warm temperatures. A new low pressure system will bring some rainfall by early Tuesday morning, and persist until early Wednesday morning. By the end of next week, some cooler air coming down from Canada will help lower our temperatures slightly, making it feel slightly more comfortable to be outside.
