While a lot of uncertainly exists, it appears the weather pattern will change across the Ohio Valley after Matthew lifts north. The long-range models show a trough developing across the eastern half of the country, bringing with it a more prolonged period of cooler weather. High temperatures will likely fall back into the 60s with lows back in the 40s. If Matthew does happen to shift onshore into New England late this week or during the weekend, then it is possible even colder air will funnel in on the back side, sending temperatures into the 30s.
It is important to note though, if Matthew does stay out to sea, then the Climate Prediction Center believes warmer than average temperatures will return to our area and could stick around through the rest of autumn.
Isn’t it amazing how one storm can make such a huge difference? It is the “butterfly effect” in action.
