With high pressure to our south, the return flow around the back of that high will usher in some much warmer temperatures for our Sunday with highs approaching 80°. Skies will remain mostly sunny with some mid and high level clouds approaching overnight.
Clouds will thicken up on Memorial Day but showers will hold off until late in the day with the best shot at them across the Adirondacks into the North Country. Highs will be near 83°.
Tuesday is when summer will really show up with higher humidity, temperatures well into the 80s and scattered PM showers/thunderstorms. The best day for showers/storms will be Wednesday as it looks now.
Have a great weekend!
