Low clouds and foggy conditions are sticking around the positions of Southern Arizona Friday morning.
The Tucson office of the National Weather service says fog is blanketing parts of Santa Cruz and Cochise Counties and that radar shows low clouds lingering in some parts of metropolitan Tucson.
Visibility is reduced to about a quarter mile or less in foggy areas.
Conditions are to improve later today, the agency said.
Friday's high temperature in Tucson is expected to be about 46 degrees, dropping to 28 degree overnight.
A hard freeze warning is in effect from 3 a.m. to 9 a.m. Saturday. The high will be about 52 degrees.
The forecast calls for temperatures to rise to normal levels next week.
