Sequence of low pressures to affect region
This week, a fairly active weather pattern is in place, with a sequence of low-pressure systems marching across the country and bringing periods of bad weather to New England. The first was a mid-level shortwave trough that passed through last night. Tomorrow will be calm, but clouds will increase tomorrow night as a warm front pushes through ahead of the next system. There is uncertainty as to how much precipitation that system will bring, but there remains the possibility of rain showers on Wednesday. More certain is a cold front that will pass through on Thursday, which will cause high temperatures to struggle to reach 50°F. The timing is subject to change, but as of now it looks like Thursday afternoon and evening have the highest chance of rain. That low should move out in time for Friday to be sunny, but chilly.
