Dry, windy conditions are expected to pose a risk of wildfires across Maryland on Wednesday, with highs in the mid-50s in the Baltimore area.

A red flag warning is in effect from noon to 8 p.m., with relative humidity low around 25 percent, winds expected to gust to 30 mph, and relatively dry brush. Such a warning means "critical fire weather conditions" are occurring or will soon, according to the National Weather Service.

Lows were expected in the 30s overnight, rising a few degrees past 50 in the afternoon. Baltimore-Washington International Thurgood Marshall airport may have tied its record low for April 3, reaching 27 degrees early Wednesday, according to preliminary data.

High pressure is forecast to keep sunshine overhead. Breezes could be about 10-15 mph, with gusts of 20-30 mph.

Thursday is expected to bring one more day of sunshine, with calmer winds and highs again in the lower 50s, before a rainy system arrives overnight. 

A 60 percent chance of rain is forecast Friday during the day.
