High pressure dominates most of the eastern half of the United States, but a cold front over the western Great Lakes is clouding our skies here in central New York. These clouds are going to prevent us from warming, and as a result we’ll have yet another day in the 40s. We haven’t seen temperatures stretch out of the 40s since before Halloween, but changes are on the way…
During the day tomorrow, the aforementioned cold front will stall and even begin to retreat north as a warm front, the leading edge to much warmer air. This will be in response to a developing area of low pressure on the western end of the front. This low is forecast to move into the upper Mid-West by Saturday evening. The upshot of it all is for an abundance of cloud cover tomorrow along with a few passing showers, but warmer temperatures. We should be back into the mid 50s for Saturday afternoon with much of the day being rain free.
The warm front is forecast to move well north of the region by Sunday morning, thus brisk south to southwest winds will import unseasonably warm air into the region. The combination of sunshine and brisk southwest winds should push temperatures to near or even above 70°. The unseasonably warm air should last into Monday.
Eventually all good things must come to an end, and a cold front will drag through the region by Tuesday. The latest look at our computer models shows the front coming through before daybreak Tuesday. With that transition will likely be showers and possibly some thunder. With the cold front moving through sooner and a quicker arrival of colder air we’ve also introduced some snow showers to go along with the rain showers on Tuesday. Chilly temperatures should last into Wednesday.
