Sunshine, temperatures in 20s after single-digit lows early Friday

The "polar vortex" was expected to make a marked return to Baltimore on Friday, with single-digit lows in the suburbs and highs only in the lower 20s on the last day of meteorological winter.

Temperatures reached 11 degrees at Baltimore-Washington International Thurgood Marshall Airport, 13 degrees in the Inner Harbor, and 7 degrees in Westminster early Friday morning. A northwesterly breeze of 5-10 mph made it feel as much as 10 degrees colder.

Clear, sunny skies were forecast through the afternoon, with highs in the lower 20s but with a slight wind making it feel like the teens.

The forecast suggests a record could be threatened. The coldest high temperature here on Feb. 28 was 25 degrees in 1934; Baltimore missed a record low of 5 degrees, also set in 1934.

Clouds were expected to move in by Friday evening, with cloudy skies Saturday, highs in the lower 40s and lows around freezing.

A potentially icy or snowy system was expected to arrive Sunday. Rain could start Sunday afternoon, with highs again in the lower 40s, turning to a wintry mix Sunday night.

A wintry mix was expected to continue throughout Monday, with highs in the mid-30s, and then with a period of snow as temperatures drop back into the upper teens Monday night.

Cold was forecast to continue Tuesday, with highs below freezing and lows in the teens.

An earlier version of this post misstated the records for Feb. 28.
