Weekend Washout? Storm to Cross New England This Weekend

The parade of low pressure systems moving through New England will continue this weekend as another cut off low forms over the Great Lakes and pushes into New England for the weekend. This storm has the potential to give New England another decent soaking from Friday night through Sunday.


As the storm system slowly meanders across New England, it will send plumes of moisture through the region. This system will be like most of the others we've seen throughout June, that is to say it likely won't be raining all day on Saturday, but bands of scattered showers and heavier downpours will rotate through the region.


Expected weather Saturday afternoon, you can see overall heavier rain around the Green and White Mountains as the center passes Cape Cod:



Before the arrival of this low pressure system, instability will allow for some thunderstorms to erupt Friday afternoon, mainly across interior northern New England. Bands of rain from the system will likely begin to arrive in New England overnight Friday night and spread eastward throughout the day Saturday.


Most of New England will be seeing scattered showers and downpours throughout Saturday. The daylight hours Saturday is when the bulk of the rain will fall. Along with showers and downpours, there could be some embedded thunderstorms as well.


After a mainly dry morning, much of Maine will get into the storm by Saturday afternoon with the bulk of the rain likely arriving Saturday evening and into the overnight hours as the storm center continues to push eastward. Northern Maine will see the least rain.



By Sunday, the system will be pushing away from New England. The storm is moving slowly, so clouds and showers will linger into Sunday morning. Another round of scattered showers and isolated thunderstorms will be possible Sunday afternoon.


Sunday afternoon, continued light showers:


Saturday will be cool, with highs likely rising five degrees or less for much of New England. Maine will see temperatures rise more as the system naturally arrives there a bit later. Highs will be in the 60s region wide.


In the end, a widespread half inch to an inch of rain is expected by the end of the weekend. The highest totals will likely be across western New England and into the Green, White and Maine mountains, where over an inch will be possible. Amounts generally taper off as you head eastward.




The cold front associated with this system looks to stall to New England's south, keeping cooler weather around and continued unsettled weather. Interestingly, northern areas of New England appear to have a better chance of warmer temperatures than southern New England heading into next week as a ridge of high pressure sets up shop in eastern Canada. There are some indications of a Rex Block developing next week.


A Rex Block is a block where a high pressure is located directly over a low pressure. Exactly where this block sets up is still very much in question (its mere formation is not even locked in yet), but this could bring New England a break in this unsettled weather at the latter half of next week. We'll have to keep watching.


Potential Rex Block situation with high pressure near New England and low pressure near Virginia late next week. Being a week out, plenty can change:
