Discussion
An approaching strong cold frontal system combined with a vigorous upper level low will help to generate numerous showers and thunderstorms this afternoon and evening throughout the Mid-Atlantic region. Some of the rain that falls will be heavy at times and some of the thunderstorms can reach strong-to-severe levels. Flash flooding is a serious concern; especially, in those locations pounded by yesterday's strong storms and heavy rainfall. Another 1-3 inches of rain can fall this afternoon and tonight as this cold front grudingly works its way through the region and there can be some shower/thunderstorm activity lingering in the area during tomorrow morning. Much more refreshing air will push into the region later tomorrow with a noticeable drop in humidity levels.
Elsewhere, very chilly air for this time of year invaded the Upper Midwest/Northern Plains on Monday with low temperatures this morning as low as the upper 30's in some spots (e.g., Hettinger, North Dakota). Minneapolis had its coldest high temperature ever yesterday for July 14th at 65 degrees and the "Home Run Weather" app index only reached a 5 out of 10 last night for the MLB Home Run Derby. Tonight's All-Star game in Minneapolis should be one of the coldest on record with temperatures likely to drop from the 60's into the 50's. This very chilly air mass for the middle of July will modify some as it heads into the Mid-Atlantic region later tomorrow, but temperatures here for the rest of the week will be below normal.
