Discussion
A cold frontal system passed through the region late last night and has ushered in the coolest air mass of the season so far and it will stick around into mid-week. In fact, temperatures late tonight should drop to the upper 30's in many suburban locations and frost is even possible in nearby places to the north and west like east-central PA, northeastern PA, and interior upstate New Jersey. Strong high pressure will expand eastward from the Upper Midwest later today and control the weather pattern around here right through the rest of the week.
