Early Week Weather

An active pattern of weak weather systems will keep the weather busy this week but with few significant impacts.

Low pressure moved into the area yesterday and is only slowly drifting eastward. While most of the area is free of the snow this morning, there are a few flurries and squalls, mainly across the southern half of the region.

These snow showers should diminish as the morning goes on, and the afternoon will see some sun poke out between the clouds. By sunset, there may be more sun than clouds, and mostly clear to partly cloudy skies will persist into the early evening.

Winds will be from the northwest at up to 10 mph through the daytime hours. Top gusts should be around 20 mph. The winds will drop to around 5 mph this evening and turn to the west, then southwest.

Temperatures will mostly be in the low 30s today. As usual, some warmer areas are likely along the I-90 corridor, while some higher elevations may struggle to get above 30.

The temperature will have a quick drop this evening with low and mid 20s common along with some colder pockets. As the winds shift, temperatures will come back up overnight, with temperatures of 25 to 30 degrees by daybreak.

By Tuesday morning, clouds will be thick once again and some light snow will move in. This snow will weaken as it arrives and may even dissipate altogether as early as the midday hours. Accumulations will remain under an inch.

Winds will remain out of the southwest, which should nudge highs into the mid 30s. Temperatures will only drop a few degrees Tuesday night with clouds and west-southwest winds around 10 mph.

Slight Warm Up

Wednesday looks like the best chance for a completely dry day this week. Winds will be unfavorable for lake effect and high pressure will nose in between weather systems. Temperatures will push to near 40 degrees, though higher elevations will stick to the 30s.

The wind will pick up Wednesday night with speeds around 15 mph from the south. This will keep temperatures from falling further than the mid 30s.

Precipitation will move in Wednesday night as well. While the precipitation may start off as some snow, it should mostly turn to rain by dawn Thursday. Periods of rain will persist through Thursday morning before tapering off to a few afternoon showers.

It will remain breezy with wind speeds of 10-15 mph. The wind direction will become more westerly early on and should end up from the west-northwest by the afternoon. Thursday will be the warmest day of the week with highs in the mid 40s.

Cooler air will move back in on northwest winds on Friday. The wind should not be as strong as Wednesday night or Thursday, but a few gusts as high as 30 mph may be possible.

Some limited lake effect will be possible southeast of Lake Ontario. The details this far out are fuzzy, but overall, it does not look like a significant lake effect event.

Another weak system will move in for next weekend. Right now, the best chance for snow will come on Saturday. Once again, snow amounts look minimal.

Temperatures will stick to the 30s through the weekend with our unsettled cool pattern possibly extending into next week as well.
