SYNOPSIS

19/852 AM.

Dangerously hot temperatures will continue all week. Coastal areas likely peaked Tuesday, while valley and interior areas continue to peak through Friday. Dense coastal fog may is possible early Friday morning. Temperatures lower significantly over the weekend, but remain well above normal into next week.

LONG TERM (SUN-WED)

19/221 AM.

After the 5-10 degree drop Saturday along with some possible coastal fog Sunday morning, temperatures will slowly start to increase again starting Monday through the middle of next week. Not expecting temperatures to be as hot as this week, but still 15-20 degrees above normal, with a less than 5% chance of reaching 100 in the valleys.

As for rain chances, the GFS and EC deterministic runs are dry through the 28th, looking at their respective ensembles and ensemble AI projections, rain chances were pushed back to the 29th or 30th of March at the earliest. Even then, projections are still very light in accumulations, and not even close to significant at this time.
