A frost advisory remains in effect for Delaware and Otsego counties as temperatures may fall into the mid 30s tonight. This is especially true for the eastern half of Delaware and Otsego counties. High pressure will result in quiet weather for most of the week ahead. Our next storm system will bring us some rain on Friday. It should be off to the northeast by Saturday, leaving us with a dry weekend. Temperatures this week will be seasonable with highs in the low to mid 60s.
Drier air continues to filter in from the east allowing us to see mostly clear skies. In fact, the air to our east is so dry that the dew points are in the 30s. Dew point is a way to measure how much moisture is in the air. This is important in our forecast tonight because when we have clear, calm nights like we will have tonight, our air will cool down to the dew point temperature. As a result, we will see areas of patchy valley fog. More importantly is the potential for the air to cool into the low to mid 30s in the Catskills. This is why the National Weather Service issued a frost advisory for Delaware and Otsego counties through 9am Monday. Further west toward Binghamton, dew points are in the low 40s. Therefore, most towns will bottom out in the low 40s tonight.
A large ridge of high pressure will control our weather for much of the work week. This will result in a mix of sun and clouds all week long with very little chance of rain through Thursday.
A weak front will cross the area Wednesday but it will only produce clouds. Rain is not expected until later this week when a more organized storm system moves across western New York.
Models are in excellent agreement regarding a storm system to deliver rain on Friday. The storm looks like it will be moving fast enough to pull the rain away from us for Saturday. Both days next weekend look dry. Overall, temperatures all week long will be seasonable with highs in the low to mid 60s.
