A cold snap that's kept temperatures more than 10 degrees below normal this week is just about over, according to the National Weather Service.
Temperatures, which reached a high of only 49 degrees Tuesday, will climb into the mid to upper 50s today, the weather service said.
The warmer conditions and mostly sunny skies are being brought on by high pressure building over the west today, forecasters said.
A developing eastern Pacific trough will again increase cloud cover on Thursday and also bring a slight chance of showers to the southern Sierra Thursday night and Friday, forecasters said.
Temperatures will reach normal to slightly above normal levels Thursday and Friday, climbing into the low 60s, forecasters said.
