High Pressure Builds In

A large, dominating high pressure system is building into the Finger Lakes from the west.

This high will be with us into the weekend, keeping our weather mild and dry.

There are a few clouds passing through the region on the front side of the high this morning. No rain is falling from any of these.

As the clouds move out, sunny skies will take over and remain in place for much of the day. Only a few fair weather clouds and some thin cirrus clouds will develop from time to time.

North and northwest winds will blow at around 5 mph today, with gusts peaking around 15 mph. The winds behind last night’s front will keep the humidity low with highs reaching the low and mid 80s.

Tonight will be mostly clear, though some occasional cirrus clouds will continue to be possible. Low temperatures tomorrow morning should range from near 60 to 65 degrees.

Thursday and Friday will be similar days, with plenty of sunshine, a few clouds here and there, and no precipitation. Temperatures will remain in the low and mid 80s. Of the next three days, tomorrow seems the warmest by a degree or two.


Weekend Weather & Beyond

Saturday will simply continue the trend we are setting today.

There should be plenty of sunshine and no precipitation. Winds will be light, though their direction will change to the southeast.

A southeast flow tends to warm the northwestern half of the region, so mid or even upper 80s could be possible. Further southeast, low to mid 80s are more likely.

Uncertainty begins to creep up on Sunday. Some models bring a cold front in on Sunday, resulting in cooler temperatures. The European model, which in most cases is the one I find more trustworthy, delays the front until Monday morning.

If the front holds off as the Euro indicates, temperatures Sunday will continue to be warm, with at least mid and upper 80s, but also perhaps a couple places reaching 90 degrees. If the front is moving through though, 70s would be more likely.

Whether the cooler air comes in on Sunday or Monday, it will eventually come. Showers and thunderstorms will accompany its arrival, though the timing of the front will dictate how much rain we see.

Temperatures during the first half of next week should stick to the 70s. The coolest day looks to be Wednesday when seeing highs in the upper 60s is not completely out of the question.
