Halloween Forecast

A chilly air mass is in place across the Finger Lakes today and will stick around into the first few days of November.

Areas southeast of Lake Ontario are starting out cloudy this morning with a few spits of rain or snow. Further west in the region, skies are starting clear. Temperatures are in the low and mid 30s where it is cloudy, and mainly in the upper 20s where it is not.

Winds will shift this morning to the southwest, removing much of the lake effect from the area. However, clouds should increase due to the daytime heating cycle. There will probably be some breaks of sun here and there, but for the most part, it looks like a fairly cloudy day.

Most of the time it will be dry during the daytime hours, though a stray flurry or shower in the far west is possible off Lake Erie. These will increase slightly and spread east during the early evening trick-or-treat period.

Still, for the most part, it will be dry early this evening, and any precipitation that does fall should be light and brief.

Temperatures will rise into the low and mid 40s this afternoon. Early evening temperatures will mainly be in the mid 30s. Overnight lows will end up ranging from the mid 20s in the western Southern Tier to the low 30s along the lake shores and in the Syracuse metro area.

Another wind shift will take place during the overnight, resulting in a few more flurries crossing the region.

Winds will end up back from the northwest early Wednesday morning with some snow showers south of Lake Ontario. A few of these may briefly reduce visibility and partially coat grassy and other cold surfaces.

A few flurries may linger into Wednesday afternoon. Overall, however, the precipitation will diminish. Breaks of sun will also be possible.

Wednesday will be the coolest of upcoming days, with most areas not escaping the low 40s with highs in the 30s for higher elevations. Northwest winds will be blustery as well, adding to the chill. Expect wind speeds over 10 mph with gusts to 30 mph.

Dry, Milder Weather

With partly cloudy skies Wednesday night, temperatures will bottom out with widespread mid and upper 20s throughout the region. Only a few select areas will stay near 30 degrees.

Thursday will start to see a rebound in temperature with a mix of sun and clouds and a steady southwest wind. High temperatures will be similar to or a bit warmer than Monday was, with mid and some upper 40s.

Winds will turn to the south Thursday night and will remain steady. Overnight temperatures should range through the 30s.

Friday will be similar to Thursday, only a bit warmer. South and southwest winds will remain steady and skies will be mixed. Afternoon highs should be in the low and mid 50s, with even the coolest of higher elevations flirting with 50 degrees.

Weather systems will begin to approach the region this weekend, mainly sticking to our north. This may bring a few scattered showers Saturday and Sunday, but as a whole, neither day looks too wet.

Both weekend days will see mild temperatures averaging out in the mid 50s. Sunday should be the warmer of the two days by a couple of degrees, with some areas sneaking into the upper 50s. With daily average highs now only around 50 degrees, these temperatures are now slightly above average.

Unsettled weather will become more likely next week, starting with a cold front on Monday. By the end of the week, as the weather settles down, temperatures may not be much warmer than they are now.
