Nice Weather Tuesday

High pressure will keep the weather quiet and pleasant across the Finger Lakes on Tuesday.

A few areas have seen a little very light lake effect snow overnight as winds turned northerly ahead of the high.

Any lingering lake effect will quickly dissipate this morning as high pressure moves directly overhead.

Even with high pressure over the area, some high and mid level clouds will pass through the area thanks to the jet stream also being directly over the area.

Still, a good amount of sunshine is likely today. Temperatures are starting the day in the teens, but should warm to near or maybe just above 30 degrees today.

That is pretty close to the normal temperatures for mid-February.

As high pressure moves east of the region, winds will swing around to the south, kicking off a warming trend.

Turning Mild

Temperatures this evening will slip back into the mid and upper 20s, but then will start to creep back upwards overnight.

By Wednesday morning, temperatures should be back into the low 30s. Once the sun is up, temperatures will rise quickly through the 30s and into the 40s.

High temperatures Wednesday afternoon should reach the low 40s for most areas with a few spots reaching the mid 40s.

Sunshine will be harder to come by on Wednesday. A couple spits of rain may even be possible very early in the morning as the warm air starts to move north in earnest.

Rain showers will be more likely Wednesday evening as another push of warm air moves north.

Again, temperatures will initially drop a little Wednesday evening, but will then rise again overnight.

Morning temperatures Thursday will be near 40 degrees before rising into the upper 40s.

Thursday will be cloudy with a couple stray showers, but much of the day will end up dry.

The best chance for rain will come on in the predawn hours on Friday with showers lingering into the daytime hours. Rainfall amounts should remain under a half-inch.

Cooler air will briefly work in behind this rain, but more mild temperatures are likely next week.

Quick Clarification

In yesterday’s post, I took a look at the longer range forecast for the remainder of February and March.

The general trend is for temperatures to be above normal.

I would like to stress once again that this does not mean that winter is over or that Spring will truly come early.

Sure, there will likely be some spring-like days, and as we get towards late March, Spring usually starts to nose in anyways.

Above normal may simply mean more 40s than 30s, such as will be the case later this week. There will still likely be shots of wintry weather, too.

Only time will tell how the day-to-day weather will evolve over the coming weeks.
