Monday's dry and mild weather in Harrisburg is not a sign of things to come for this week.
Clouds will increase across the Harrisburg area on Monday, but temperatures will be trending in the opposite direction than on Sunday.
Instead of cooler air arriving, a southerly breeze will pump in milder air that will push temperatures to the 50-degree mark.
A high of 50 F in Harrisburg is more common in the middle of March than this time of year.
The end of the dry spell will coincide with sunset Monday as some rain will move through Monday night.
A bit of the rain may linger into Tuesday morning with clouds winning out over sunshine this day. The air will still be warmer than normal with a high in the upper 40s expected.
The air will not be cold enough for the rain to mix with or change to snow.
AccuWeather.com meteorologists are monitoring the possibility of whether the same can be said for Wednesday.
The quick passage of a cold front would be accompanied by a thin line of rain showers that day. The development of a storm along the East Coast, on the other hand, could bring steadier rain or snow to the city.

In either solution, the upcoming weekend is shaping up to be chilly.
Following a dip in temperature during the middle of the week, summerlike warmth will rebound across much of the Northeast by this weekend.
