Forecast discussion: Happy Easter to all. Well, as expected, high pressure did give us some sunshine in the early part of the morning, followed by increasing clouds. The latest radar imagery shows showers now moving into central Connecticut. Eastern Massachusetts should see a few showers within the next couple of hours.
A warm front ahead of the precipitation is the root cause, and this front will continue to move eastward through Sunday evening. We may see periods of heavy rain at times this evening, but should only last for about four or five hours. We will also see patchy fog after midnight. The precipitation will come to an end on Monday morning, but the dry weather will be brief. The cold front associated with a Canadian low will move through in the afternoon, helping to trigger another round of showers by the evening commute. In fact, with the warmer temperatures, a rumble of thunder or a widely isolated thunderstorm is possible before sunset.
By Tuesday, a new cold front from Canada will push through the region. This front will be dry, but it will bring colder air coming down from Hudson Bay. Our high temperatures will only reach the middle 40’s. Overnight lows will fall below freezing. Temperatures will slowly increase to near normal conditions by Thursday.
As we move into Friday, the computer models suggest a low pressure system bringing thunderstorms to the Southeast U.S. moving in a north-northeast direction, bringing more precipitation by the morning. The European model suggests we could be on the very edge of the precipitation shield, while the United Kingdom model keeps the low just offshore on Saturday morning. For now, I will keep showers and moderate rain in the forecast, starting late Friday morning. All precipitation ends by early Saturday morning, as the low moves towards Nova Scotia. A quick moving low pressure system along the northern U.S. may give us some showers next Sunday morning.
