MANCHESTER, NH — When April showers freeze up, it puts the ice-y in dicey.
The National Weather Service has issued a winter weather advisory that remains in effect until 8 a.m. on Monday April 16 for Manchester and the surrounding region. Expect to hear the pitter-patter of a rare late-season wintry mix Sunday, propelled by a cold air mass which will keep temperatures below freezing over most areas. Light freezing rain is likely with areas of sleet and some snow as well Sunday.
A frontal boundary is slowly lifting north across northern New Hampshire and western Maine. Mixed precipitation will track northward across the area overnight Sunday. Temperatures are expected to remain near to below freezing overnight. Freezing rain and sleet are expected, but some snow may mixing in at times. The cold air will be slow to erode on Monday, and some mixed precipitation may linger into the daytime hours Monday. Untreated and elevated surfaces will be icy through the morning.
Deepening low pressure will cross New England Monday and Monday night, bringing a period of heavy rainfall to the region. Rivers are already running fairly high with snow melt, and the addition of heavy rainfall will increasing the flooding potential.
