Much of the upcoming week, which features the start of astronomical spring, should be dry, but on the cool side.
We start the week off with high pressure building in, but a series of weak upper-level disturbances will move through as well. What that means is that we may start each day with some sun, but clouds will quickly fill in, with just a slight chance for a pop-up shower today and Tuesday. Some gusty winds are expected both days, and temperatures will be near or even a little below normal for the latter half of March. A weak low pressure area will move across the region on Wednesday, bringing in more clouds and a better chance for some showers. With some rather cool air aloft, some of these showers could contain some graupel, which is just soft hail, or even some wet snowflakes. High pressure builds in for Thursday with sunshine, breezy, conditions and cooler weather. The high hangs on into early Friday with dry weather, but the weekend looks unsettled at this point.
The weekend forecast is very uncertain at the moment. Most of the model show a coastal low developing off the Mid-Atlantic coast and heading off toward the Northeast. But that’s about the extent of what they agree on. Some keep the storm too far south to have little or no impact on the region. Some bring it close enough to bring some rain in, and some have a weak disturbance ahead of it that may bring in a little snow to start, especially across the interior. At this point, it’s too early to tell which scenario is right, so we’ll just play the middle ground for now, and hope to have a much better idea of what will happen by the time we get to our Weekend Outlook on Thursday.
