Summary- The basic pattern consists of high pressure over the southwestern US and Great Basin/Rockies, with SW flow to the west of Oregon. This upper high is helping tropical cyclones to develop off SW Mexico and south of Baja Calif. Troughing still occurs in the westerlies, but the westerlies are displaced well to the north now during the early to mid-summer period. Moisture for TSTMS in the SierraNV continues somewhat limited. A pool of cooler than normal sea surface remains in the tropical region S thru WSW of southern Baja Calif. This will discourage intensification of tropical cyclones during July. It also contributes below normal moisture into Baja Calif, resulting in drier than normal conditions in Baja, NW Mexico, and S Calif during July. Monsoonal moisture is still present, but travels northward thru mainland Mexico, and into New Mexico, east Arizona, and the southern Great Plains. El Niño continues, but is subdued as is typical in mid-summer. Some redevelopment of El Niño is possible in mid-winter 2018, but forecasted results are inconclusive.
