Cool Air

A large area of low pressure is centered over Michigan this morning.

There are two primary cold fronts associated with this low pressure. The first has already moved east through the Finger Lakes and has knocked temperatures back into the 40s this morning.

Rain showers are also moving through this morning in association with this first cold front. These showers will continue to slowly lift northeast and should mostly be out of the region by the midday hours.

The afternoon will be relatively quiet. There will even be an opportunity for some breaks of sun during the late morning and early afternoon hours. Late in the day, a few more showers will pop up with the second cold front. These should be less widespread and shorter lasting than the rain this morning.

During the quiet part of the afternoon, temperatures will rise into the mid and upper 50s. A few places, mainly in the Southern Tier and around Dansville and Ithaca, may briefly reach 60 degrees.

Winds will be nearly calm for much of the day but will pick up from the southwest during the mid and late afternoon. Wind speeds of 10-12 mph will become likely, though these winds may not make it north of I-90. A few gusts to 30 mph will be possible.

The wind will be short-lived and will lessen as the sun sets.

Evening temperatures will slowly slide back through the 40s and should end up in the mid 30s overnight. A few pockets could dip below freezing, mainly in Steuben, Allegany, and Wyoming counties. Scattered showers will continue overnight, changing to flurries for many areas. No more than a light coating of snow is expected.

Tuesday will be cloudy and cool with occasional rain showers and some early and late flurries. Winds will remain from the southwest with speeds near or just over 10 mph. Top gusts should be around 25 mph for most areas and 30-35 mph along and west of I-390 in the western Finger Lakes.

Highs will only make it into the mid 40s. This is about ten degrees below average for this time of the year.

A few flurries will be possible Tuesday night, but overall, precipitation will start to become more isolated. Temperatures will reach their coldest point of the week, dropping to the low 30s. A few pockets could end up in the upper 20s.

Temperatures Rebound… Briefly

Wednesday may have an early flurry about, and clouds will likely persist into the afternoon. Eventually, though, some sunshine should start to break through the clouds as northwest winds pivot to a more westerly direction late.

Temperatures will nudge closer to average with upper 40s and low 50s. The wind may be blustery at times with speeds over 10 mph and gusts just shy of 30 mph.

Wednesday night will see temperatures in the upper 30s with partly to mostly cloudy skies. Thursday will also have mixed skies, and a few showers may also be possible during the morning.

Temperatures are the least certain on Thursday as a warm front moves into the region. Highs should easily make it into the 60s as long as the front makes it into the area, but could push into the 70s if it is even more progressive.

Friday has an even better chance of being very warm with highs at least in the 70s likely. The uncertainty is lower on Friday, but there is still some present.

Saturday, too, is looking uncertain, this time as a cold front moves into the region. The timing of the front will determine how temperatures evolve throughout the day, as well as the rain chances.

An area of low pressure may also develop along this front and could bring heavy precipitation to the area, either later Saturday or into Sunday.

Temperatures will take another dive and will be about as chilly early next week as they are early this week. The cool air looks to be a bit longer lasting, though, with highs not confidently returning to the 50s until late next week.
