After a winter storm dumped about a foot of snow on some of San Diego County's mountain ranges, a warm-up is coming, but we'll see a few cold days and nights first.
San Diego County saw some of the coldest temperatures of this winter season -- and likely the year -- overnight Thursday, NBC 7 Meteorologist Dagmar Midcap said.
Multiple regions in Southern California, including Vista, El Cajon, Palomar Mountain and Lake Cuyamaca tied or broke their previous record-low maximum temperatures, according to the National Weather Service.
The cold night came as a powerful winter storm moved out of the San Diego region. The storm left behind at least 14 inches of snow on Mount Laguna and 6 inches of snow in Julian, according to the NWS' latest tallies.

While there is no more rain in San Diego's forecast through February, cold temperatures will remain. Although a warming trend is beginning, it'll take a few days before we reach average temperatures for San Diego this time of year.
Temperatures Thursday were expected to be about 5 degrees warmer than Wednesday, but it'll still feel cold to San Diegans used to 75 degrees most of the year. Highs were expected to remain in the low 60s for the coast, the valleys and the deserts, while the mountains see temperatures in the low 40s.
A frost advisory will again be in effect from midnight to 8 a.m. Friday for the deserts and valleys, including Escondido, El Cajon, San Marcos, La Mesa, Santee, and Poway.
By Saturday, temperatures will start to normalize. Highs will be 5 degrees below average in the mountains and valleys, about average in the valleys and about 5 degrees above average along the coast.
