Squeezing Out Another Dry Day
Most of us will squeeze out another dry day today with a slight chance of a few showers well north and west of Boston. As high pressure continues to lose control, a frontal boundary will begin to affect the region by Wednesday.
Mid-to-late week: Wednesday...A frontal boundary travels from west to east allowing showers and rumbles of thunder to sweep across Southern New England. Then,the surface low and upper level low collaborate late Thursday into a vertically-stacked low, which is a sign of weakening. This low pressure will act as the toy 'sit 'n' spin' through Friday. Minor disturbances (shortwaves) spiral around the low pressure center. This will induce diurnal cloud cover in addition to a few showers, especially during the afternoon hours. Highs will be in the lower 60s Wednesday...near 60F Thursday...middle 60s Friday.
Mother's Day Weekend: Tough call! I can say that most of the weekend will be dry, but the models continue to depict discrepancies. The EURO is now showing a few showers possible Saturday and Sunday afternoon as the flow of the jetstream would allow 'lil shortwaves to produce a few raindrops. However, the GFSx is forecasting a dry day on Saturday with a surface low/upper level distrubance passing to our south on Mother's Day. So, if the GFSx verifies, I'd say there is a chance of afternoon showers across Southeastern Mass. on Sunday. The good news is that the weekend will NOT be a rain out.
