Chance of rain, cooler temps in store this week

This week’s temperatures will be cooler than the record breaking highs over the weekend and there is a chance of rain Wednesday night, National Weather Service meteorologists predict.

Sunday in Sonora reached a high of 88 degrees, breaking the 1950 record high of 85 degrees. 

The historic average temperature for the weekend dates was 69-70 degrees. 

Warm temperatures in the Mother Lode over the weekend ranged from 87 in Twain Harte and 86 in Columbia, to 92 in Copperopolis on Sunday.

Highs today will be around 75 in Sonora and Angels Camp, NWS meteorologist Jason Clapp said this morning.

There is a chance of thunderstorms over the High Sierra, but in the Tuolumne-Calaveras region, there is a 60 to 70 percent chance of light showers on Wednesday night into Thursday. 

Tuesday’s highs will be in the lower 70s to upper 60s. Wednesday highs will be in the mid-60s and Thursday will be the coolest day of the week, with highs in the mid- to upper-50s, Clapp said. 

Friday will be warmer, with temperatures reaching the mid-60s. Warmer temperatures will arrive this weekend, Clapp said.
