Snow showers and squalls possible for Saturday

2/19/2022

Back to winter

Picture
After the recent warm up, the reality of where the point of the season returns for the weekend. A spicy clipper passes through the region Saturday. The breeze returns from the south / southwest which warms the shorelines up, but most areas stay below freezing for the day. With the warm air creeping in aloft from the southwest flow, clouds increase. As the system approaches, snow showers break out. 
Picture
Saturday 8 AM to Sunday Midnight - Snow appears relatively light for most of the day. Squalls arrive late afternoon over western and southern areas and then move eastward through mid-evening. The squalls could produce whiteout conditions and a quick burst of accumulating snow of upwards of an inch or two. Be aware of rapidly changing conditions if you are out on the roads later in the day and evening. 

Wind increases with the passage of the front tonight, with gusts from the west / northwest at 30 - 40 mph for few hours as the system moves east. Any snow that falls may blow around and reduce visibility in spots at times until the wind settles down heading into Sunday morning. Expect wind chills below zero in the north and single digits for the coast.

Another inside runner on the way
​Tuesday into Wednesday

Picture
Monday 7 PM to Wednesday 7 PM - High pressure that keeps the region quiet through Sunday and Monday moves eastward. A southwesterly flow develops, and mild air returns starting Tuesday and continues to get warmer into Tuesday night. A storm forming over the Great Lakes Tuesday heads along the St. Lawrence River Tuesday night. Coastal areas see rain develop in the afternoon Tuesday. The mountains and foothills may deal with freezing rain at the onset which could impact evening travel. The question at this point is how far north the warm air surges as that impacts precipitation type and for how long that type falls. At this point, most of the state can expect rain out of this system with ½-1+" possible Tuesday night into Wednesday. With the parent low intensifying through Quebec, wind out of the south could bring potential for power outages along the coast. For those with shoreline interests, the 3 AM hour Wednesday high tide may bring some minor flooding and splash-over, and should be monitored for impacts there.

Snow possible late in the week

Picture
There is a signal showing potential for a snow event later in the week, but for now confidence is low being 7 days out. Guidance is hinting at a Miller B type nor'easter which could bring heavy snow for interior areas and a mixed bag for the coast, along with gusty winds. For now, it is something to watch and stay updated on as the week unfolds.

Newsflash: winter is not over.

Be aware of snow squalls

Picture
Snow squalls are short, intense bursts of snow and wind that can catch people off guard. They can reduce visibility and cause dangerous travel conditions. If possible, avoid or delay travel until the squall passes. If you’re caught in one, slow down, turn on your headlights and hazard lights, and try to exit the road. Stay on alert, and make sure you have a way to receive alerts!
