'Potentially headline-worthy accumulations' late Saturday and again Monday with one-two Arctic punch

Spring is over for now.

Winds, associated with a passing cold front, will gust at close to 50 mph today and blow much of the warmth right out of the Buffalo Niagara region by later Friday. A wind advisory is in effect until 11 p.m. for Erie, Niagara, Chautauqua, Cattaraugus and Wyoming counties.

First comes a cold rain, then expect the snow.

A trough of Arctic air behind another passing cold front Saturday will change precipitation from liquid over to snow later in the evening as temperatures plunge.

A "general inch or two of snowfall" is expected across Western New York by daybreak Sunday, according to forecasters at the National Weather Service.

Because the frigid flow will be coming from the northwest as well as the presence of available moisture in the atmosphere - and that lakes Erie and Ontario are open and relatively warm (about 40 degrees) - there's a potential for the lake-effect snow machine will get revved up again.

Here's what weather service forecasters say about that:

SEVERAL ADDITIONAL...AND POTENTIALLY HEADLINE-WORTHY...INCHES OF
ACCUMULATION WILL BE POSSIBLE WITHIN THE REGIONS OF LAKE EFFECT/LAKE
ENHANCEMENT SATURDAY NIGHT.

The areas most likely to be affected will be found southeast of the lakes. More specific forecasts, with potential snow totals, are expected by Friday.

The snow should taper off by the middle of Sunday morning, the weather service said, but it's going to be cold.

Again, in the words of weather service forecasters:

WITH RESPECT TO TEMPERATURES...THE INCOMING ARCTIC-SOURCED AIRMASS
FOR SATURDAY NIGHT AND SUNDAY WILL RESULT IN READINGS MORE TYPICAL OF
JANUARY OR FEBRUARY THAN OF EARLY APRIL...

Overnight lows Saturday night and Sunday night will be in the lower 20s. The mercury will struggle to escape the upper 20s during the day on Sunday and will only make it to about freezing on Monday.

The average high temperature for this time of year is about 50 degrees.

The second-punch comes late Sunday night into early Monday.

A "diving" Canadian Clipper system behind the trough of Arctic air is forecast to track over the Buffalo Niagara region or sufficiently close enough to bring more snow.

ON SUCH A TRACK...THIS SYSTEM WOULD BE LIKELY TO BRING A
GENERAL SYNOPTIC SNOWFALL TO MUCH OF OUR REGION...WITH ANOTHER ROUND
OF POTENTIALLY HEADLINE-WORTHY ACCUMULATIONS EVEN POSSIBLE SOUTH OF
LAKE ONTARIO WERE ITS TRACK AND TIMING TO LINE UP JUST RIGHT.

Added weather service forecasters:

NEEDLESS TO SAY...THIS IS YET ANOTHER SYSTEM WE WILL NEED TO KEEP AN EYE ON
OVER THE COMING DAYS.
