Central Pennsylvania is gearing up for a wet and potentially stormy start to the week as the remnants of Tropical Storm Chantal merge with an incoming cold front. The National Weather Service is predicting widespread showers and thunderstorms, particularly on Monday and Tuesday, with a high likelihood of precipitation across the region.
Residents can expect scattered thunderstorms to develop Monday afternoon and into the evening. The northwestern areas face a marginal risk of severe weather, with forecasts indicating the possibility of heavy rainfall. The heat index is also expected to rise into the 90s in many valleys south of the northern tier, leading to humid and uncomfortable conditions.
Temperatures are forecasted to reach the mid-80s to around 90 degrees on Monday, accompanied by increasing moisture and cloudiness throughout the day. Specific counties, including Lancaster, Dauphin, and Lebanon, are noted as particularly vulnerable to significant rainfall due to the storm dynamics at play.
As the cold front progresses, unsettled weather will persist into Tuesday, and thunderstorms will remain a possibility, increasing the risk for torrential rain and isolated flooding in several areas. While temperatures will drop slightly, the humidity is likely to remain high, creating a heat index that could approach 100 degrees in parts of the southeast.
Looking ahead, the extended forecast suggests a shift toward a more variable weather pattern for the rest of the week. Wednesday appears to offer a reprieve with lower chances of precipitation and only isolated showers anticipated, especially in the southern regions. However, conditions may again become stormy from Thursday through Friday as warm and humid air remains dominant.
Residents are urged to stay vigilant, monitor up-to-date local forecasts, and be ready for potentially severe weather conditions over the coming days.
