Any Californian who has simply had it with May’s gray, soggy chill had to hate the Memorial Day weekend. Rending asunder holiday plans of grilling at the park, or maybe some beach time, the final days of the month continued a statewide stretch of unseasonably cold, wet weather. On Sunday and Monday, precipitation fell and temperatures dropped, establishing daily records across the southern two-thirds of the state, from Modesto to Death Valley (0.04 inches of rain Monday).
