High pressure continues to dominate our weather pattern and will get the week off to a warm start.
The primary high is centered over the southeastern United States, but an elongated axis of high pressure extends north-northeastward over the Finger Lakes and into eastern Canada.
Light southwest winds will blow today as the center of the axis sets up just east of the area. This will allow warmer air to move into the region, especially for the western half of the area.
Skies will once again be sun-filled. There are a few early clouds over the far northeastern Finger Lakes this morning, but they should not last long.
The influx of warmer air and the sunny skies will help temperatures warm significantly today. Mid 60s will be widespread for areas west of Cayuga Lake, with highs closer to and just above 60 to the east.
Skies will start clear this evening, but some clouds will start to roll in after midnight. Southwest winds will increase a little, but speeds will stay under 10 mph.
The clouds and wind will keep temperatures in the 40s for all but a few cold pockets in the Southern Tier where some upper 30s will be possible. Across the northern half of the region, many areas will stay near or above 45 degrees tonight.
Tuesday will be rather cloudy, but no rain is expected during the daytime hours. The best chance for some breaks of sunshine will be in the midday and early afternoon when one batch of clouds departs and a second area moves in.
Winds will turn from the southwest to the northwest, but speeds will stay near or under 5 mph. By the late afternoon, the wind will be nearly calm.
Without the sun and consistent southwest wind, temperatures will take a step back but will remain well above average. Look for highs mostly in the upper 50s with a few mid 50s east of Cayuga Lake and in the higher elevations of the western Southern Tier.
A batch of light rain will move into the area Tuesday evening. These showers will be quick moving and should only stick around for a few hours. Many areas will see less than a quarter-inch of rain, but some areas, mainly near Lake Ontario, could approach a half-inch.
The rain should be long gone by Wednesday morning. It will again be a relatively mild start to the day with mid 40s throughout much of the region.
Sunshine will increase Wednesday morning and skies will be mostly clear for the afternoon. Northwest winds will blow at around 10 mph, especially during the morning.
Temperatures will settle mostly in the low 50s, though a few areas in the vicinity of I-90 could poke into the mid 50s. Mostly clear skies overnight will allow temperatures to fall back into the low and mid 30s by Thursday morning.
Clouds will gradually increase on Thursday. Like Tuesday, rain will approach but looks as though it will hold off until the nighttime hours. This batch of rain looks heavier, with some areas approaching an inch. The rain will taper off Friday morning.
Temperatures will remain on the warmer side with highs in the mid 50s both Thursday and Friday.
The weekend is less certain. Another cold front should move through on Saturday with rain showers. There is a small chance for some snow to mix in as the front drops temperatures, but it is much too early to tell if the precipitation will end before the colder air moves in or not.
Sunday looks cooler with highs returning to the 40s. There will be some precipitation off the Great Lakes, but at this early stage, it looks mostly like the precipitation will fall outside of our area.
Next week looks cool and unsettled. Highs may struggle to get beyond 40 degrees at times, which means not everything that falls will be rain. However, there are hints at a couple days of warmer weather late next week as well.
This graphic represents an average over the entire Finger Lakes region. Localized variations should be expected.
