A FROST ADVISORY IS IN EFFECT FOR DELAWARE AND OTSEGO COUNTIES FROM 2AM UNTIL 8AM MONDAY.
• Wide temperature range tonight; coldest east.
• Scattered frost possible in the Catskills; isolated frost possible elsewhere.
• Most of Monday is dry; best chance of late day showers is in Finger Lakes (30%)
• Seasonable temperatures for most of this week.
• Lots of uncertainty in the Wednesday through Sunday forecast; due to cutoff low pressure.
• Slight shift east or west of low pressure could increase or decrease precipitation chances.
• Keeping 30% chance of showers to account for uncertainty Thursday-Friday; 20% Saturday.
Another mainly clear and cold night is ahead for us tonight. The best chance of frost is east of Binghamton in the Catskills, but isolated frost is possible in the normally coldest valleys elsewhere, too. A Frost Advisory is in effect for Delaware and Otsego Counties from 2am through 8am Monday. Lows will likely range from the low 30s to mid 40s.
Clouds will increase Monday and most of the day looks dry. I have kept a slight chance of some late day rain showers in the forecast for the Finger Lakes, but most of the area will be dry through 8pm. Rain chances will increase to 60% overnight Monday with the passage of a cold front. A rumble or two of thunder can not be discounted. Highs will be in the mid 60s.
The cold front should push well east of the area overnight Monday. Clouds and rain will decrease as dry air, associated with an upper level low pressure, arrives through the day Tuesday. I expect mostly sunny skies Tuesday with highs in the mid 60s.
Unfortunately, at this time, there is a decent amount of uncertainty in the forecast Wednesday through Sunday. The uncertainty is caused by a ‘cut-off’ low pressure system that will meander in the southern Great Lakes and Ohio Valley. For now, I’m leaning toward the system being far enough to our southwest that it will not bring us showers each day. However, if this system changes positions, east or west, by just a few hundred miles, it would have big forecast implications for us. A shift farther west likely means lower chances of rain, but a shift east could bring more showers and unsettled weather. We’ll monitor the position of the low and update the forecast accordingly.
As far as precipitation chances, I’m going with 30% for Thursday and Friday and 20% Saturday. Highs will be seasonable in the mid 60s with lows in the 40s to near 50.
