Severe weather is likely in areas that are in the yellow and dark green. Strong heating will result in weak to moderate instability by afternoon and isolated to scattered strong to severe storms will be possible. A slight risk has been placed for the Northern corner of the state which could bring damaging wind, hail, and severe thunderstorms. A marginal risk has been placed for much of the center of the state, including the Pittsburgh area and areas north of the city, and a thunderstorm risk (mostly isolated, non-severe storms) has been placed for much of the eastern half of the state. Thunderstorms may be isolated and or may pop up randomly in some areas and will more than likely not produce anything damaging.
Any storms that are able to develop could pose a threat for locally strong wind gusts and perhaps some hail. Given the conditional and isolated nature of the threat, low-end severe probability appears appropriate at this time. Because of the instability of a very moist and unstable airmass due to a cold front that is dropping across the southeastern region, storms may or may not be isolated and severe. The areas in a slight and marginal risk have a greater chance of seeing severe weather.
