The sunshine will prevail today. A storm system far offshore will be slinging clouds toward southeastern Massachusetts though. However, the sunshine will struggle to push the mercury into the lower 40s. It’s going to be a chilly one. Thankdully, it won’t be windy so the uwind chill will not be a major factor.
Thursday and Friday will be filled with sunshine as well. Highs will remain cool on Thursday with highs in the lower 40s while Friday will be milder near 50F.
This weekend’s pick day will be Saturday with plentiful sunshine and seasonable highs in the middle 40s. Then, the storm system moves in on Sunday and hangs on through Monday. We know that a storm system will be affecting us, but the question that is still tough to ‘nail down’ is the type of precipitation that will be falling. The 540 line will be bobbing through our viewing area. It still appears that the best chance of a wintry mix/snow will be north of the Mass Pike. We will need to watch this track very closely. It may require a lot of nowcasting in terms of where the rain/snow line sets up and determining who may see accumulating snow. Some areas across northern Mass. and southern NH (north and west of 128) may be reaching for their shovels. The potential for accumulating snow will be Sunday night and Monday. There are signs that cold air damming will be occurring during this event too.
It’s still far into the future, but next Wednesday is showing more signs of a coastal storm potentially heading our way. The track of the jetstream will be positioning us in the ‘line of fire’ with a more ampified pattern/troughy pattern for the Eastern half of the Nation.
