New England Weather This Week: Mixed Bag...Again

This week in New England will feature a few quick-hitting disturbances, with generally low impacts expected. Here's the details:


MONDAY


Monday will see increasing clouds across New England as the region's next system begins to move in from the west. The day will remain dry for all of New England with temperatures cooler than the weekend thanks to cooler nighttime air getting trapped at the surface for today. Highs will generally be in the low 50s in southern New England and the low 40s to about 50 in northern New England.


The storm system will pass to New England's north overnight. This will drag the system's warm front across New England, putting New England into the warm sector. Showers won't begin until well after sunset, closer to midnight for most of New England. Showers will generally be light and scattered, with no more than a quarter inch of rain expected anywhere, most areas will see even less.




There is a chance for some mixing in the higher elevations of northern New England before the warm front arrives, switching the precipitation to all rain. Some snow will be possible across northernmost Maine, with up to an inch or two possible through Tuesday morning.

TUESDAY & WEDNESDAY


The storm is quick to exit amid strong zonal flow across the United States. Lingering showers will generally shut down by the morning. New England remains in the system's warm sector for most of Tuesday before a cold front moves in. This will lead to a mild and breezy day with highs generally in the 50s north and 60s south with partly to mostly cloudy skies.


As the storm pulls away, it will drag its cold front across New England from northwest to southeast. This front will usher in much cooler air for the region (compared to Tuesday highs) along with additional scattered showers. Cold front showers will be most numerous in the afternoon across northern and western New England.



The timing of the cold front has been trending faster, but it will take time for the air to cool behind the front, so Tuesday is still looking to be a mild day (highs were written above). By Wednesday, the front will have cleared the region, leading to a much cooler day. Highs Wednesday will be in the 40s for most, with higher elevations of northern New England remaining in the 30s. The day will be dry and generally brighter than the start of the week.



THURSDAY


The next system is looking to arrive in New England Wednesday night into Thursday. Right now, it does appear that it will be cool enough for snow or mixed precipitation across New England early Thursday morning, with any frozen precip changing to all rain for southern New England by Thursday afternoon.


For northern New England, mixing and/or snow showers may linger through most of the day, leading to a cool, raw, messy day. Any accumulations (rain, sleet, ice and snow) across all of New England (northern and southern) are currently looking to be minor with a couple inches of snow possible in the mountains and rainfall at a quarter inch or less. There's still plenty that needs to be worked out with this system, we'll be watching the trends closely over the next couple days.

FRIDAY


Another quick moving storm is looking to pass on Friday. As of now, it looks like this (weak) system will move south of New England, keeping a majority of the precipitation out of the region. Another system to the north may bring scattered showers to the higher elevations of northern New England. Exactly how these systems play out is still up in the air a bit, so, like the Thursday system, we need to keep watching the trends. Highs will remain on the cool side of seasonable for the end of the week.


GFS showing the storm passing to the south of New England, other major models generally agree with a drier outcome for Friday as well:


WEEKEND


The weekend is currently looking to be dry for the most part, with currently no signals for any major storm systems. Some small-scale, weak disturbances may trickle through, leading to scattered, light showers, mainly for northern areas. We'll need to watch the trends on the Friday system.
