Discussion

After the two warmest days of the spring so far on Sunday and Monday, big changes are on the way for the eastern part of the country. An impressive cold front is moving west-to-east this morning towards the east coast and it will bring a significant rainfall to the Mid-Atlantic region along with persistently strong winds and isolated thunderstorms. The front will usher in much colder air to region by the end of the day and there is a chance that it will get cold enough for lingering rain showers to mix with or change to sleet and/or snow this evening with the greatest chance for this possible changeover in the western and northern suburbs. Temperatures by tomorrow morning will be below freezing in most Mid-Atlantic locations and patchy frost is likely early Thursday morning. This late season cold shot will be quite widespread with well below normal temperatures by tomorrow extending from Canada all the way down to the Deep South.
