Forecast discussion: After rain last night, Providence did see a little sunshine this morning and early afternoon, before a mix of clouds and sun took over the late afternoon. However, winds did increase, with gusts of 35 mph this afternoon. We will see an evening of dry weather, before a low pressure system that could create a derecho for the Great Lakes and Ohio River Valley moves towards New England tomorrow afternoon.
Right now, a Flood Watch is in effect for all of Massachusetts, except for the Cape and Islands, until 8 a.m. Saturday. A strong low pressure system will bring another round of showers by Thursday afternoon, with heavier rain arriving by the start of the evening commute. Isolated thunderstorms are possible. Computer models are predicting we could see another 1 to 3 inches of rainfall by the time this low moves offshore Friday afternoon. This extra rainfall could create some street or river flooding, especially during the morning commute Friday morning.
As we approach the weekend, a high pressure in the Northern Plains will bring drier weather and warmer temperatures. We will be in the upper 70’s in Saturday, with partly sunny skies for Father’s Day. However, we will not be able to escape the precipitation. A new low pressure system will be moving south of New England Sunday evening. It will not bring much rainfall, and showers should end by early Monday morning.
As we move into the middle of next week, the models seem to disagree on a low pressure system in the Central U.S. The American model wants to give us scattered showers Tuesday night into Wednesday. The European model keeps the low far enough south, so we will see dry weather. At this time, I am not very confident in either model at this time, due to the forecast being seven days out. So, I will go with the European model, as it has done better as of late in long range forecasting. I will give us partly sunny skies, with no precipitation.
