Brooklyn residents are feeling the chill as they step outside this morning, with temperatures dropping into the low 20s for the first time this winter.

Temperatures tomorrow are only expected to drop more, with a low in the teens and sub-zero wind chills. Those who have to walk to school or work, or wait outside for public transportation are advised to bundle up.

Fortunately, Mother Nature will give everyone a bit of a break later in the week, warming things up to a not-so-freezing 30 degrees.
