Overview

• Temperatures across Chicagoland and the Northeast are running 5–20°F below seasonal averages, with highs in the low 60s inland and 50s along the lakefront on Sunday.
• Gusty winds of 25–35 mph are affecting areas like Boston, with cooler air continuing to settle into the region through the start of the week.
• Light rain is expected to develop late Monday into Tuesday, followed by a stronger coastal low bringing wind, heavier rain, and highs in the 40s to 50s from Wednesday through Friday in the Northeast.
• The cool pattern is tied to a springtime weather trend of deep troughs funneling Canadian air into the U.S., resulting in unseasonable temperatures and stormy conditions.
• A gradual warming trend is forecast to begin by Memorial Day weekend, with highs rebounding to near-seasonal averages in the upper 60s to low 70s.
