…WINTER WEATHER ADVISORY REMAINS IN EFFECT FROM 10 PM THIS
EVENING TO NOON EST WEDNESDAY…
* WHAT…Snow expected. Total snow accumulations of 1 to 4
* WHERE…Portions of northern Connecticut, south central and
portions of eastern Massachusetts as well as Rhode Island.
* WHEN…From 10 PM this evening to noon EST Wednesday.
* IMPACTS…Plan on slippery road conditions. The hazardous
conditions could impact the morning commute.
* ADDITIONAL DETAILS…Rain changes to snow from northwest to
southeast between 10 pm tonight and 4 am Wednesday, but that
process may not happen until near daybreak across portions of
the Cape. Biggest concern is the Wednesday morning commute,
especially across Rhode Island and southeast Massachusetts.
Slow down and use caution while traveling.
A cold front will push the warm and rainy conditions currently affecting us out to sea. Behind it, cold northwest winds will cool things down quickly, but a small storm will develop along the frontal boundary as it exits our area.
This will be a storm with only minor total accumulations. However, given that it may be snowing during rush hour, expect delays and slippery driving conditions on Wednesday morning. It will be a tough call for administrators on school cancellations on Wednesday morning, since the heaviest precipitation will be falling during the hours of 4AM – 10AM.
1-3″ is expected in most locations, but 2-4″ could fall in a few spots, especially south and east of Providence, based on the track of the storm along the front. Dry air will limit snowfall as you get farther northwest. Snow should end by late afternoon. It will be cold and blustery Wednesday night into Thursday.
This post will be updated as needed.
