California’s heatwave forecast will be mortally rivaled in July 2006

The hot wave that began Friday in California could compete with the deadly seven-day heat event in July 2006, the National Weather Service said.

The valleys, mountains and deserts of Southern California are likely to see daytime and nighttime temperatures challenge records through at least Thursday, and humidity will make conditions feel 2 to 5 degrees warmer during the day.

Extended views prepared by the National Oceanic and Atmospheric Administration favor temperatures above normal that remain long after Thursday.

The excessive heat is the result of a large, strong high-pressure system centered over Arizona, which keeps the southwestern United States almost everywhere except within a few miles of the coast.

High pressure over southwestern California on Tuesday will reach a strength that only occurs about every ten years, says Eric Boldt, a meteorologist with the National Weather Service in Oxnard. This dome of high-pressure air blocks storm systems and creates construction heat over the southwest.

It was during the deadly heat wave of 2006 that Los Angeles County recorded its highest temperature ever: 1

19 degrees in the Woodland Hills on July 22nd.

The Times reported that offenders in Los Angeles, San Bernardino and Kern counties linked about 130 deaths to the heat, with diagnoses including hyperthermia and heat flux. However, government researchers later estimated that tolls in these counties were more likely to range from 350 to 450.

This time, California is throwing into the state heatwave with the ongoing COVID-19 pandemic as a kind of preexisting state.

The National Weather Service warned on Friday of the real potential for heat stress and heat flow with the current heat wave.

Valleys in the Los Angeles region can expect heights of 100 to 108 degrees, with low levels from 72 to 82. Elevations below 5,000 feet will amount to heights between 98 and 105 and low ranges from 65 to 75. High temperatures are 102 to 112 in the Antelope Valley, with lows from 70 to 80. Coastal areas can look for elevations of 82 to 92 and lows of 65 to 70.

Critical heat will occur between 11.00 and 19.00 daily, especially inland, says the weather service. Night temperatures do not cool enough to provide comfortable sleeping weather in many places.

Short elevations to critical fire conditions will be present daily during the period, with concerns about the risk of a new fire start from isolated dry lightning strikes. Plume-dominated fires can lead to rapid fire spread and locally unpredictable winds.

There is a risk of thunderstorms on Saturday, and again Sunday to Tuesday, when monsoon humidity is expected to return. Even if it’s not raining where you are, the humidity will probably provide the kind of unpleasantly harsh conditions that Californians are largely unfamiliar with. Heavy rain and floods could follow all thunderstorms.

Monsoonal rain in the southwest has at best continued to be disappointingly spotty, according to the latest US drought monitoring report, released on Thursday. Some parts of the southwest expect to receive half of their rainfall during the North American monsoon. Parts of Arizona and New Mexico endured temperatures that were 3 to 5 degrees above normal during the past week.

Although California’s drought conditions remained roughly the same, the extreme drought in the west expanded by almost 1.4%. Areas in the west that are estimated to be in moderate drought grew by 1.3% and areas with severe drought increased by almost 1%, according to data from the US drought monitor.
