The main reason that the daily average temperatures and liquid precipitation across the entire region was skewed warmer and drier was that for approximately the first 2/3 of the month, it was significantly warmer and drier than normal for all 4 climate sites and for all of the rest of Southeast Alaska as we remained under a dominant strong blocking ridge of high pressure for the vast majority of that time. The weather for about the last third of the month was much more normal for the Panhandle with frontal systems pushing through, some with associated Atmospheric Rivers, bringing cooler and wetter conditions to the entire region, moderating the final temperature averages and precipitation amounts a bit for the month to make them not quite as significantly warm and dry as they would have been if the trend that started the month had carried through to the rest of the month. According to the U. S. Drought Monitor, appreciable drought conditions were still being experienced over the southern third of the Panhandle toward the end of the month with only marginal improvements. As far as records are concerned for the month, on August 4th, Juneau Airport hit 82, which broke their old high temperature record of 80 degrees set in 1999. On that same day, Sitka Airport hit 79, which broke their record of 74 degrees set in 2009. On the 5th, Juneau Airport tied their old record of 81 degrees, which was originally set in 2017. On the 6th, Juneau Airport tied their record with 81 degrees, once again, which was originally set in 2023. Finally, on the 18th of the month, Juneau Airport, once again, tied a record high temperature. The record was 79 degrees, which was originally set back in 1977. Chambers $$
