![]() ![]() If that happens, expect a fair number of news headlines since that also happens to be the single hottest reliably recorded temperature on Earth. One searing statistic: the official recording site in Death Valley has a decent chance of tying (or even) breaking its all-time record high temperature of 130F. Additionally, the ECMWF ensemble is suggesting a relatively high probability that some places in the San Joaquin Valley could reach or exceed *all time* temperature records on Sunday, which are generally in the 114-118F range in that part of the state. On Sunday and Monday, however, numerous calendar date record high temperatures will likely be tied or broken across the Sacramento (locally 110F+) and San Joaquin (locally 115F+) Valleys, as well as the southeastern deserts (Palm Springs will hit 120F+). This will be a widespread heatwave across the entire Western United States, with record temperatures possible in some interior portions of the Southwest and California. Record temperatures are therefore unlikely in this pattern along the coastal plains. ![]() But you won’t have to go very far inland (only 10 or 15 miles) to see a dramatic increase in temperatures–so this will be a very “inland-aligned” heatwave (common earlier in the summer, unlike “coastally-aligned” events in autumn). The marine layer will still be greatly suppressed, so expect a minimum of coastal fog and genuine t-shirt weather even in the usual coastal cool spots. This will not be an extreme heatwave along the coast–the coastal parts of the SF Bay Area and Los Angeles/San Diego metros will certainly be warmer than usual, though not very hot. Each day will likely be hotter than the last starting tomorrow across the CA interior, with temperatures peaking between Saturday and Monday in most spots. ![]() As this ridge expands and strengthens, a major heatwave will develop from south to north across California into this weekend. Hotter and drier air aloft is making its way westward from the Desert Southwest, where Phoenix is likely to break (potentially by a wide margin) its record for the greatest number of consecutive days at or above 110F. Well, that anomalous coolness in California is rapidly disappearing as I type–a very strong and highly anomalous (2-3 standard deviation 500mb GPH anomaly) is expanding and deepening across the interior Southwest. Severe & prolonged heatwave focused across the SW interior, including CA Central Valley & SE deserts, peaks this weekend Depiction by ECMWF ensemble of very strong/potentially record-breaking ridge over the Desert Southwest this weekend. Speaking of that rapidly warming Earth: in great contrast to recent temperatures in California, the last week now appears to have been the warmest week on record globally–blowing well past previous records as record-shattering marine heatwaves in both the Atlantic and Pacific as well as record-breaking terrestrial heatwaves in regions ranging from the Canadian Arctic, Southern Europe and northern/eastern Africa, as well as parts of SE Asia persist. For more details on whats happening in that region, see analysis here: /Jl8oj6zlwJ- Zeke Hausfather July 11, 2023 We saw many regions setting new all-time records, with the North Atlantic in particular standing out. In fact, it appears that some areas along the immediate coast near the SF Bay Area and the SoCal metro areas (which, as I often point out, is cumulatively where the vast majority of Californians actually live) just experienced their coolest June since at least the late 1970s (a remarkable achievement in a rapidly warming climate globally). After a brief warmer lull in the late spring, anomalous coolness once again pervaded most of California during June. Although parts of the North Coast have actually been warmer than average during this period, most of CA was well below average and a few small but highly populated corridors along the immediate central and south coast were the coolest on record for such a period since at least 1979.Īs many have noted, the coastal parts of central and southern California have been remarkably cool since about January.
