It looks like one uncomfortable week for the Dweebs next week…..Retrogression in effect now as both the upper high north of Hawaii and the upper high over the Midwest begin backing up today. Upper ridge according to the latest guidance should be east-west along the Utah/NV border with the axis through the Bay Area by Monday afternoon. This is a Hot-Dry pattern for the high country with only afternoon cloudiness or high based storms possible. Our warmest temps of the year so far will begin Monday, then continue into Tuesday, Wednesday and beyond. High temps may approach upper 80s at resort levels, dependent upon cloud cover by Thursday. Unfortunately there will be days of little Zephyr wind and so it will feel uncomfortable into the evening hours for some folks…..We’ll see how the moisture stacks up as we get further into the week.
High based thunderstorms could begin as early as Tuesday afternoon as highs get into the mid 80s at 8000 feet. Then depending upon cloud cover, 87 or even 88 may not be unreasonable by Thursday/Friday depending upon if the ECMWF is correct with its height forecast over Mammoth. Nighttime lows will be in the 50s next week. The 10th of July is usually one of our hottest days of the year historically, with low 90s during some of the hottest years. However, 90 is not in the forecast at this time on that date.
In the Owens Valley, Bishop is expected to reach 103 to 104 next week. A record high of 110 occurred on July 10th back in year 2002. That was an all time high for Bishop. That record will remain this year. Coincidentally, Mammoth Lakes had a high of 91 on that same day. The all time record high for Mammoth Lakes as recorded by the Forest Service in town was 93 degrees. The Dweebs do not have the date of that record. However, odds are that it occurred early during the month of July (pre-monsoon) so possibly during the first week of July.
