Snow & Cold Details

Low pressure over southern Pennsylvania will track northeast today, bringing a band of snow through the region, followed by cold temperatures.

As of 7 AM, the band of snow was moving into the western Finger Lakes in the I-390 region. This snow band will continue to spread eastward over the next couple hours.

Once it starts to snow steadily, it will continue for several hours. The snow will come down at a moderate intensity with a few heavier bursts and a few lulls.

Snow will taper off to scattered flurries as the steady snow ends during the early to mid afternoon hours.

Most of the Finger Lakes should see an inch or two of accumulation, though localized amounts up to three inches are likely. Three-inch amounts are most likely in the higher elevations of Central New York, as well as in the I-90 region and the higher elevations of the western Southern Tier. The best chance for under an inch will be in the eastern Southern Tier for places like Elmira and Owego.

Major roadways should remain in good condition. Traffic cameras over Western New York show a couple inches of snow on the ground, but only wet roadways. I suspect that some rural roads will become messy, though, so use caution as appropriate.

Temperatures will not move much today with most places seeing highs in the low and mid 30s. Northwest winds will be breezy with gusts of 25-30 mph.

Scattered snow showers and perhaps a brief squall or two will continue through the overnight. Locally another inch could fall, but most areas will only see a fresh coating of snow.

Widespread 20s are expected overnight, with low 20s in the western Southern Tier, and mid and upper 20s for most of the remainder of the region. Areas near Lake Ontario, and perhaps along the immediate shores of the Finger Lakes, may remain closer to 30 degrees.

A few more stray flurries will be possible on Thursday. Temperatures will start to crawl back upward. Highs in the I-90 and Lake Ontario areas will probably just get above 40. Most of the rest of the region will be near or just below 40, with mid 30s in the higher elevations.

Thursday will be windier than today, with northwest winds gusting between 35-45 mph.

Warming Trends

Skies will clear Thursday night, allowing temperatures to slip into the upper 20s and low 30s overnight. Northern areas will be warmer, and southern areas cooler, as is usually the case.

Friday will be quite sunny with just a few midday and afternoon fair weather clouds bubbling up. Highs will reach the mid 50s for most, with just a few higher elevations sticking to the low 50s. Friday night will not be as cool with lows ranging through the mid and upper 30s.

Saturday will start off sunny, but clouds will gradually increase through the afternoon. South winds will help boost temperatures into the low 60s.

The next weather system will arrive late Saturday night as rain moves in from the southwest. Rain will continue Sunday morning before tapering to showers Sunday afternoon. Wind gusts late Sunday through Monday will be between 30-40 mph, coming from the northwest.

High temperatures on Sunday will stick to the upper 40s with the clouds and rain, and Monday will follow suit with the northwest winds, despite increasing sunshine.

Warmer weather quickly moves in for the middle of next week, with highs near 60 on Tuesday and into the 70s Wednesday and Thursday. Temperatures are less certain after that, but favor warmer over cooler conditions.
