A few showers and thunderstorms will be possible late each afternoon and into the early evening hours, favoring south-central Pennsylvania and the Middle Susquehanna Valley today, and the northern mountains of the state on Tuesday. After a mild start to the day with daybreak temperatures in the 50s to mid 60s, temperatures will steadily climb to the upper 80s to mid 90s, challenging record highs for the date at many locations. Select areas of enhanced heating and lift across the ridges of south-central Pennsylvania will help to form a few mid afternoon to early evening showers and thunderstorms from the Laurel Highlands to the Susquehanna Valley. A few of the thunderstorms later this afternoon could produce brief wind gusts of up to 45 mph. Rainfall accumulations should average below one tenth of an inch with most locations likely staying dry. Partly cloudy skies and dry conditions will follow for tonight with temperatures only slipping into the 60s for overnight lows. A near repeat of the potentially record heat and isolated to scattered late day showers and thunderstorms is expected on Tuesday. A strong cold front will bring showers and scattered thunderstorms on Wednesday, some of which could be severe in the afternoon and early evening across the southeastern half of the state. Cooler, more seasonable conditions will follow for the end of the week and into Memorial Day weekend. $$ Lambert
