DAYS 1-5 (MAY 1-5)

Happy May Day! As we enter the final month of “meteorological spring” we have an upper trough over our region, but it’s not the type that’s going to give days of unsettled weather, although we could use more rain most certainly. What we have is mostly dry weather for our region through this weekend. Sun heating the ground today will initiate clouds to pop up today with the colder air aloft – typical springtime set-up. These clouds should be for the most part “fair weather clouds” but a few of them can grow enough to produce a shower later in the day or this evening. Saturday’s weather will feature less sun as the coldest air moves through aloft, with a slightly more unstable atmosphere initiating more cloudiness associated with the upper low while at the same time a surface low heading off the Mid Atlantic Coast throws its high to mid level cloud shield our way as well. That system will graze southeastern New England Saturday night with a bit of rain for Cape Cod and possibly RI and the MA South Shore, but I expect it to be staying pretty far offshore and moving fairly quickly so that by Sunday it’s moving away. We will still have a pool of cold air aloft on Sunday so look for additional clouds to pop up with a few showers possible. The upper low starts to make its exit by Monday when it warms up a little, but a disturbance moving in from the west can bring some additional cloudiness and perhaps a few showers later in the day. Looking ahead a bit more, right now Tuesday is looking like a dry and mild day as an area of high pressure slides to our south.
