Sunshine may be a little hard to come by this week for an extended period, but rainfall won’t be, which will help with the ongoing drought. At least it’s not snow, right?
The weather pattern to start the week across the nation is dominated by a pattern known as an “omega block”. With upper-level troughs of low pressure in both the East and the West, and a ridge of high pressure in the middle, the pattern resembles the Greek letter Omega. With an upper-level low in the East and drifting eastward slowly, that means we’ll be on the cool side to start the week, with some rainfall likely. The heaviest rain will likely fall across western New England today, but occasional showers in our area will persist today. As that upper-level low moves eastward, so will the surface low, so that rain in western New England today will shift into our area later tonight and Tuesday. Wednesday shouldn’t be as wet, but with the upper-level low moving across the region, we’ll still have some showers around. By Thursday, we may dry out a bit, but with another upper-level disturbance moving in, some more showers are possible.
As we get to the end of the week and into the weekend, the upper-level low hangs around, and a surface low pressure system will be moving up the coast, bringing more rain and cool temperatures into the region. For Sunday, many of the models try to have high pressure building in with drier and milder weather. However, we know that the models struggle in this type of pattern, and historically are too quick to improve conditions around here. So, even though the models are forecasting Sunday to be rather nice, we’re going to hedge our bets a little. We should have a better idea how the weekend will play out for our Weekend Outlook Thursday afternoon.
