Baltimore's latest 'first freeze' since 1994 forecast to come by Saturday

Temperatures are forecast to plummet by the weekend, bringing Baltimore its latest first freeze of fall since 1994.

Lows are forecast in the mid-30s early Friday, threatening a freeze, and the mid-20s by early Saturday, ensuring one. But in 90 percent of years, freezing temperatures would have already come by Wednesday’s date, according to the University of Maryland Extension.

The last time the first freeze did not come on or before Nov. 8 was in 2004, and in that year, it came Nov. 9. But in 1994, it didn’t arrive until Nov. 12.

So far this fall, 35 degrees has been the coldest reading at Baltimore-Washington International Thurgood Marshall Airport, the region’s point of record, coming Oct. 27.

Areas farther from Baltimore’s urban heat island, and at higher elevations, have already experienced their first freeze.
