Baltimore hits 80 for fourth day in a row; rain, chill ahead

It's 80 degrees for a fourth-straight October day in Baltimore, but rain and a chill are coming.

Temperatures reached 80 degrees at Baltimore's point of record for the fourth day in a row early Thursday afternoon, but a significant chill and some rain are ahead.

Baltimore/Washington International Thurgood Marshall Airport reached 80 degrees by 2 p.m., according to the National Weather Service. BWI hit 83 degrees Monday and 84 degrees and 87 degrees the following two days, setting new record highs Tuesday and Wednesday.

The region had not experienced such prolonged warmth since Sept. 14.

It was Baltimore's longest streak of 80-degree October weather since 2013, when the month began with six consecutive days in the 80s or lower 90s. Before this month, Baltimore had not hit 80 degrees in October since Oct. 28, 2014.

High temperatures this week have been 15-20 degrees above normal for this time of year as a high pressure system off the southeastern U.S. coast circulates warm air in from the south and southwest.

A cold front is forecast to bring a dramatic change in weather pattern Friday.

Rain is likely during the day Friday as the front approaches, and showers could continue through the night. Temperatures are expected to peak in the lower 70s before falling to the upper 40s by early Saturday morning, a swing of more than 30 degrees in about 36 hours.

Rain clouds are forecast to clear out by Saturday morning.

Despite the sun, temperatures are expected to rise only to the upper 50s during the day Saturday and to the lower 40s by early Sunday. More seasonable highs in the 60s are forecast going into next week.
