High pressure stretching from Eastern New York to Nebraska will slide south Thursday evening opening the door for a cold front to swing through on Friday. A strong dome of high pressure will rebuild for the weekend setting the stage for a sunny and dry weekend.

Another mainly clear evening ahead for Thursday as high pressure is in full control. Lows tonight won’t be as cold as they were last night. This morning’s low ended up at 46°, a few degrees cooler than I had expected. The big difference tonight is a wind shift turning southwesterly driving in some milder air.

The day on Friday will begin tranquil. The front I mentioned above will begin to move through during the early afternoon. I think the best potential for showers will be mainly to our east where moisture parameters and dynamics are more aligned, but we’ll definitely see thickening skies. Perhaps a sprinkle for Monroe County, but that’s about it.

Friday night will be by far the chillest night we’ve seen in months. All locations, expect near the lake, will see temperatures plummet into the low to mid 40s in Monroe County. Expect upper 30s south of the Thruway and even upper 20’s east of Lake Ontario.

Saturday and Sunday will both be mostly sunny. Saturday will be the cooler of the two days with those low morning lows expected, but temps will rebound nicely to the upper 60s. We’ll do a few degrees warmer on Sunday as readings will climb into the low 70s.
