Dangerous heat will continue until Friday and Saturday before slowly easing

The Central Coast is bracing for a sweltering weekend as a heatwave hits the region.

Today we had a delicate scenario for the high temperatures. We did indeed reach record values, but not exactly in the places where the climatology is kept. Suffice it to say that it was hot and record-breaking, but 2020 and 2022 were very hot and some of the records will be difficult to beat despite the hot forecast:

The most severe weather conditions are expected on Friday and Saturday, when temperatures will be 15 to 20 degrees above normal.

The reason for this heat wave is a high pressure system over Southern California. This system compresses the atmosphere, causing even higher temperatures. In addition, offshore winds push warm air from inland toward the coast, which further increases the heat.

I should also note that with the hot temperatures Friday, some models are showing some thunderstorm potential in the Ventura mountains and perhaps eastern SB County. The model also shows some scattered activity moving in from the south Saturday afternoon. The chances are slim, but not zero.

While temperatures will gradually drop from Saturday, the heat will continue throughout the weekend. One can expect temperatures between 40 and 45 degrees in the valley even on Saturday, offering little relief from the scorching temperatures. Nighttime lows will also remain unusually high, making it difficult to recover from the heat of the day.

Heat warnings and advisories

Heat warnings and advisories have been issued for much of the Central Coast, highlighting the dangerous and potentially deadly nature of this heatwave. Residents are urged to take precautions, stay hydrated and avoid strenuous outdoor activities during periods of peak heat.

Strong sundowner winds expected

Strong sundowner winds are expected on Friday evening, potentially affecting the entire south coast. These winds can spread wildfires quickly, so extreme caution is advised.

Gradual cooling next week

A welcome cooling trend is expected to begin on Sunday and continue throughout next week. Temperatures should return to near-normal levels by midweek. However, the forecast remains subject to some uncertainty as models indicate the possibility of persistent offshore winds. If this occurs, temperatures on the coast and in the valleys could be warmer than currently forecast.

Stay safe in hot weather

Remember to take care of yourself and your loved ones during this heatwave. Be mindful of elderly neighbors and those with health problems, and never leave children or pets unattended in the car.
