Somewhat cooler and drier air entered the state Monday evening, temporarily breaking the ongoing heat wave. Afternoon high temperatures fell back into the mid-90's for Tuesday and Wednesday. On Thursday morning temperatures dropped into the 60's. With the exception of the beaches, which enjoyed a welcomed sea breeze, inland counties observed hot, dry weather into the weekend. Late Sunday a weak frontal boundary passed southward through the state but failed to generate any widespread rains. Many sites report less than one half an inch of rain over the past month. The absence of wet weather coupled with 100 degree heat and high evaporation rates have all greatly stressed shallow rooted plants. Statewide temperatures for the period averaged five degrees above normal.
