AM All Zones Update: Snow and ice threat for the interior Sunday

/by

Clouds will be around much of the day, as a warm front lifts through region. But some breaks of sunshine are likely as drier air moves in to the mid-levels of the atmosphere. A southwest flow developing near the surface today will also help temperatures warm into lower to middle 40s. However, weather conditions will take a turn for the worst again late tonight and tomorrow morning, as a storm system approaches the region. Clouds will increase again overnight, thanks to some warm-air advection aloft, and some light precipitation could break out sometime closer to daybreak.

PM Zones (N NJ, NYC, CT): Light snow likely tonight

/by

Calm and pleasant weather conditions dominated the day today, with breezy conditions from earlier this morning tapering off a bit as the day went on. The weather will remain for the next few hours, but sun will become filtered by high and eventually mid clouds near sunset. The weather will become unsettled again later today and tonight as a disturbance and associated low pressure area approach.

This low pressure area will be driving from Southaest Canada into New England, eventually to a position off the coast of New England. The storm system is not deep or amplified, and will remain very progressive. But bands of snow are likely to move from New York State through Southern New England tonight, possibly clipping parts of Northern New Jersey, NYC, and Long Island.

Mid-AM All Zones: Multiple wintry events in New England

/by

An active pattern, which has existed across the Eastern United States for the better part of the past 3 months, will kick into even higher gear later this week into the early part of next week, as multiple disturbances drive southeastwards from Canada into New England. These disturbances in the mid and upper levels of the atmosphere will aid in the development of surface low pressure systems, first moving through Southeast Canada and then redeveloping off the coast of New England.

Exactly where and when these surface low pressure systems develop will be the critical component to wintry weather potential in Southern New England — including parts of Central and Northern Connecticut from Friday Night into Saturday morning and again from Sunday Night into Monday morning.

2/9 PM Zones: Storm exits, more to come in New England

/by

Snow is wrapping up from west to east throughout the area this evening, including parts of Long Island where snow has lingered for the longest today. A low pressure center moved from the coast of New Jersey to a position south of New England — in fact, quite close to the 40/70 “Benchmark” for impactful storm systems. Impactful snow moved from Northeast NJ and NYC through Long Island and Connecticut, and now is positioned near Southern New England.

The storm system will continue wrapping up and pulling further eastwards as the evening goes on tonight. As low pressure moves away from the Northeast US, northwesterly winds will gradually allow drier air to move into the region. A developing pressure gradient between the low pressure center and an incoming high pressure will lead to the potential for gusty winds through the evening. This will be especially true near the area coasts, where gusts may exceed 35 miles per hour at times.
