The high pressure system that has been keeping our weather in check for the past several days will slowly loosen its grip on central New York. It looks like we’ll squeeze in one last day of sunshine and warmth before changes arrive.
When discussing the weekend forecast, we’ve been disclosing that there is a good amount of uncertainty. For one thing, computer models have been going back and forth between when the greatest chance for rain should arrive, moving it from Sunday to as early as Friday. The scene that is most likely to play out is this: a disturbance in the jet stream will drop over the Great Lakes today, tracking just to our north by Friday night. Closer to the surface, a cold front will move through central New York by late Friday, meaning a better chance for showers and thunderstorms Friday afternoon.
With the faster movement of everything, our weekend weather is looking better, albeit a bit cooler. Since this cooler air will be travelling over a warm Lake Ontario we are going to respect the potential for a bit of lake effect showers early Saturday. The set up isn’t the best so we are going to keep the chances low for now.
Outside of this lake effect our weather over the weekend will be dry but feel a bit fall-ish as a cool area of high pressure builds into central New York. Temperatures may not climb out of the 60s both Saturday and Sunday.
A nice day Monday will be followed by another cold front Tuesday with more showers and thunderstorms.
