    Light snow will overspread the state late tonight as low pressure moves in from the Ohio valley. This is a quick moving moisture-starved system so only 1/2 to 1 & 1/2 inches of snow is expected the bulk of which will occur between midnight and daybreak Friday. Skies will briefly clear out Friday afternoon and evening. A powerful winter storm will impact us this weekend. Elongated, but intensifying low pressure will develop along a strong frontal boundary on Saturday. Strong jet dynamics along with a deep subtropical moisture feed will support heavy precipitation amounts across the state. Clouds will thicken up again Saturday morning and precipitation will begin as snow in the mid to late afternoon Saturday. This snow will be heavy at times into Saturday evening. As the low makes its closest approach, the coastal front will move into parts of Connecticut during the height of the storm. A wintry mix of sleet and some freezing rain will develop from south to north Saturday night, with plain rain expected for a period of time Sunday morning at the coast. Temperatures will remain below freezing inland, while rising into the mid 30s at the coast. Precipitation will end as snow showers from west to east as temperatures rapidly fall through the 20s everywhere during the afternoon Sunday. Total snow and sleet accumulations at the coast will average 3-5 inches, inland areas 5-9 inches with 0.1″ to 0.3″ of freezing rain. Standing water and slush from any melting Sunday will ice over as a bitterly cold arctic airmass surges in. This will remain with us on Monday with highs in the teens and wind chills -5 to -15 at times. Tuesday will still be below normal with sunshine and highs in the 20s. Another weather system will approach Wednesday with rain and snow showers and highs in the mid to upper 30s.

Keep checking back for the updates on the storm through this upcoming weekend.
