On this morning’s weather map, high pressure is centered right over the region with a complex frontal boundary positioned over the upper Midwest and Mississippi Valley regions. Over the next 24 hours, high pressure will move from its current position to well off the New England coast. This will supply Central New York with a rather nice early-to-mid December day.
Meanwhile, the aforementioned frontal boundary is forecast to take up residence from the central Great Lakes southwest through to the south-central Plain States by Friday morning. This cold front is forecast to continue to advance east and should be right on our doorstep by early Saturday. Consequently, clouds will taker over this evening and tonight with showers likely developing sometime tomorrow, most likely during the afternoon.
Thereafter, there is some uncertainty as to whether or not the front stays to our north of sags to our south. This has major implications on temperatures for the day. Indications are we may catch a break with perhaps some limited sun early Sunday, before a stronger storm moving from he Plain States to the north-central Great Lakes results in afternoon showers Sunday and possibly steadier rain (and wind) Monday. With the storm track to our west and northwest, warmer air will likely surge back into the region Monday. Colder air will likely arrive Tuesday after the passage of the associated cold front.
