The heat was on in June … partially. After a very cool period around the 10th of the month, conditions changed rapidly with a warm up that saw the first major heat spike of the year between June 16-19. The majority of the western US ended up warmer than normal during the month of June (Figure 1) with the southwest and Great Basin seeing conditions 3-5°F above normal. Isolated areas around the Salinas Valley, the Bay Area, the Olympics, and eastern Washington and Oregon saw a more normal June in terms of temperatures (Figure 1). The warm up has accelerated vine growth with most regions reporting average to slightly ahead of average phenology. For the rest of the United States, the month saw a flip-flop from May with the southeast seeing slightly below normal temperatures while the east coast was near normal and everything from the Plains westward was warmer than normal (not shown).
