Our next chance for stronger storms will come in the latter half of Tuesday. We’re pretty confident that we’ll have a good environment to support strong to severe storms north of Pittsburgh, but we’re less confident that storms will be able to develop to utilize it. SPC has expanded the Marginal Risk (1/5) a bit farther south, and the Slight Risk (2/5) now clips parts of our northwest PA counties. Stay tuned for updates.
