A slight cooling begins Sunday
Warmer than normal conditions prevailed again for the Coachella Valley this afternoon as Palm Springs hit a high temperature of 94°. The average for this time of year sits at 80°. With the high of 94° Palm Springs tied the record of 94° set back in 1956.
The reason conditions have remained warmer than normal is because of an area of high pressure sitting now to the northeast. This ridge has warmed temperatures across California up to 20° above seasonal averages.
Low temperatures this evening will stay mild with most areas reaching into the lower 60's. This will be a common trend with warm and sunny afternoons, followed by cool and clear evenings.
A very slight cooling trend takes place tomorrow. Slight, as in, hardly noticeable. A semi cut-off low to the south will bring a period of onshore winds Sunday through Monday allowing temperatures to cool by a couple degrees. For coastal areas this could bring back some areas of low clouds and fog for the morning and evening hours.
Overall, temperatures will stay above normal through the week. By the time we get into Thursday and Friday cloud cover will increase more with temperatures seeing more of a cool down.
