Eyes on a weekend winter storm

Winter Storm Watch

Friday will be mild but dreary. Rain sticks around through the early afternoon but we're looking ahead to the weekend concerns.

A Winter Storm Watch has been put in effect from Saturday evening through Sunday morning for Rhode Island along with Plymouth and Bristol County, MA. Southern Worcester County is also in this Watch. The steadiest snow should come between the hours of 10pm and 5am. The timeline has come together quite nicely and the guidance models agree that it should push to the northeast by 7am Sunday. Take a look at how quickly this system moves below.

Over the past few days, the snow totals have waivered a bit. In fact, 72 hours from the event, the European model was suggesting over 8" while the American forecast was between 1-2". That wide gap has become smaller over the last day, but, the totals will depend on where this system ultimately lands. At this time, both models (as well as the higher resolution information) are suggesting is stays offshore which is conducive to snow in southern New England. But, as you can see in the images below, the two premier models differ in their location.

Regardless of which track eventually wins, it's safe to say there will be a brushstroke of 3-6" for most in RI. Lesser amounts are possible towards the Cape and Islands as some rain could mix in. This is expected to be wet, dense snow and should compact quickly.

A parking ban has already been put into effect for Portsmouth. Portsmouth Police told NBC10 the ban will last from 9pm Saturday through 1pm Sunday. I expect bans in other parts of the state to pop up ahead of this storm. If you don't like to shovel, there is some good news to pass along as well. Temperatures will be on the rise as early as Sunday afternoon. With highs in mid 40s on Sunday, near 50° Monday, and approaching 60° on Tuesday, the snow will likely melt off quickly!

Chief Meteorologist Mark Searles will have updated information about this winter storm later today. Be sure to tune into NBC10!
