High pressure will slide across the region today and Wednesday in the wake of Monday’s recent snowstorm, bringing cold temperatures and breezy conditions to the region. The minimum temperature tonight will threaten the daily minimum temperature record of 20°F (-7°C) set in 1881, highlighting the unusual nature of such intense cold in Boston so far into April. As the high pressure system pulls away, temperatures will moderate and clear skies will give way to clouds and rain on Thursday as a cold front pushes into the region. In its wake, cooler temperatures and clearing skies will return and persist into the weekend as high pressure again settles into the region.
Elsewhere across the nation, relatively tranquil weather will dominate, with precipitation pushing through the Great Lakes, Ohio Valley, and Deep South Wednesday into Thursday before approaching the Northeast. Behind the system, cooler temperatures will overspread much of the eastern United States, while warmth will persist across the west.
