On this morning’s weather map, high pressure is anchored along and just off the Mid-Atlantic and New England coasts. Farther west, a cold front is evident across the western Great Lakes and Mid-West regions.
Over the next 48 hours, high pressure is forecast to become more elongated (getting stretched north to south) as it shifts off the East Coast. Meanwhile, the cold front will move east and should be located from southern Ontario, Canada to the Ohio Valley by Friday morning. Thereafter, the cold front should push through the region and eventually clear the region Saturday morning.
This scenario projects a faster frontal passage than what was indicated earlier this week, consequently, we’ve introduce the threat for a shower or thunderstorm late Friday with lingering showers possible Saturday. The weekend, overall, looks nice with dry weather (absent the early shower threat Saturday) and much cooler temperatures as high pressure re-gains control of our weather.
High pressure will stay in control early next week, but there is some question how long that will last. Some computer models bring showers into Central New York Monday afternoon, while others hold off until Tuesday. Naturally, as we close in on early next week, we’ll be able to fine tune the details.
