Now that we’re heading into the middle of May, we’re finally getting some typical Spring weather for New England. Nothing too extreme – some mild days, some cool days, some sunshine, some rain. No snow though – that *should* be done for the year.
The week starts off with high pressure building in on Monday, giving us sunshine and cool conditions. Tuesday should be a decent day as well, but there’s the potential for it to be not so great. Low pressure should remain south of the region, but it may be just far enough north to spread some clouds in, at least to the South Coast. If the high pressure area to the north builds in enough, we’ll stay sunny and start to warm up again. Wednesday should also be sunny and mild with high pressure in control.
By Thursday, things start to change again. A cold front will be approaching from the west. Clouds will stream in ahead of the front during the day on Thursday, with some showers likely late Thursday into early Friday as the front moves across the region. Neither day will be a washout, but you may need an umbrella, especially late Thursday and Thursday night if you’re heading out.
High pressure returns on Friday with cooler conditions once again. Mothers Day weekend is a big question mark at this point. Low pressure will head towards the region, with a warm front ahead of it, and a cold front behind it. The timing of these fronts is in doubt, which has significant implications on the forecast. One model brings the warm front through early Saturday, with a mild Saturday, (below left) and a very warm Sunday ahead of the cold front, with showers in the afternoon. Another model keeps Saturday quite chilly and damp (below right), with the warm front not moving through until early Sunday, and the cold front waiting until early Tuesday before it moves through. Based on our experience, the more likely scenario is the later timing. So, even though our forecast right now is for a chilly and damp Saturday, keep in mind that conditions could be significantly better than what we’re forecasting right now.
