Good Friday morning from Chief Meteorologist Tony Petrarca
Looks like the anticipated change in the weather pattern continues as the jet stream (storm track) shifts to an extended colder period for New England and eastern half of the country. We are not anticipating record or extreme cold, but rather temperatures that are either normal or below average. The shift in the jet stream is one that favors increased chances of precipitation and with colder air in place, increase chances for snow. Our first chance of the season is this Saturday, then another possibility by early next week. Let’s break down Saturday.
The seasons first accumulating snow arrives Saturday. Expecting flurries Saturday morning turning into a steadier snow by afternoon and evening. Snow continues Saturday night and this is when most of our accumulations will occur. Roads will become slick by early evening, Snow ends early Sunday morning with improving weather. The storm is still 24-30 HOURS hours away. Things can certainly change as far as snow amounts. Keep checking back for updates now thru Friday Night.
Here is what we are thinking
EXPECTED SNOW AMOUNT BY LATE SATURDAY NIGHT…
HIGHEST AMOUNTS EXPECTED IN AREAS NORTH AND WEST OF PROVIDENCE. A general 2-5 inch snowfall is expected with the higher amounts further inland away from the shore. Amounts of 5-7 inches would be confined to northwest Rhode Island from roughly Foster to Smithfield
WHAT TO EXPECT:
With temperatures expected to be in the mid 30s during daylight hours, snow may have hard time initially sticking to roads, with better chances of road coverage at night.
We expect “daytime” wet snow to initially stick to grassy surfaces, shrubs and car tops at first (essential non paved surfaces). Bottom line, accumulations during the daytime will vary depending on varying surface types. Accumulations on paved surfaces will start near sunset.
SATURDAY TIME LINE
PRECIPITATION TYPE: Some rain and sleet will mix in across south coast, the Cape and Islands which will limit snow amounts in those locations. The outer Cape will actually get very little snow
Check back for updates Today and Tonight as the final accumulation forecast may need some adjustments
