New UPDATE, MARINE

SYNOPSIS
Issued at 153 PM PDT Mon Jun 17 2024

Dry and breezy conditions continue into Monday night. Better onshore flow and moisture return by midweek. Another warming trend on the way for the upcoming weekend.

UPDATE
Issued at 836 PM PDT Mon Jun 17 2024

The Red Flag Warning that was in effect for the North Bay Interior Mountains was allowed to expire at 8 PM this evening as relative humidity values over the region increase to 35-45 percent overnight and wind speeds reduce. However, while some moistening will occur tomorrow, there remains an elevated fire weather threat through Tuesday away from the immediate coastline/bayshore as breezy onshore flow persists. Smoke from the Sites Fire Colusa County is moving over the North Bay and part of the Bay Area this evening as transport winds over that region are out of the northeast. The ongoing forecast remains on track with no updates anticipated at this time.

SHORT TERM
(This evening through Tuesday)
Issued at 153 PM PDT Mon Jun 17 2024

Gusty northwest winds continue to mix down toward the surface this afternoon, as high as 30 mph in some of our higher locations over the interior coastal ranges and passes. The gusty winds combined with a dry air mass producing min RH values as low as 10 percent will persist for the remainder of this afternoon into the evening hours.
A Red Flag Warning remains in effect until 8pm for the North Bay Interior Mountains in Napa county. A positively tilted upper level trough will keep winds elevated wrt the normal diurnal trend overnight into Tuesday. Embedded weak shortwave ridging will help to ease surface winds Tuesday, especially inland away from the coast, however the Salinas Valley will reamin breezy as onshore northwest surface flow channels inland. Temperatures will remain near seasonal averages through midweek.

LONG TERM
(Tuesday night through next Sunday)
Issued at 145 PM PDT Mon Jun 17 2024

A warm up continues to highlight the extended forecast. Persistent upper level troughing over our region begins to shift east and flatten late Thursday into early Friday, continuing into the weekend. A weak ridge begins to build with the ridge axis just to our east over the Sierra Mountains Friday afternoon. An increase in heights and thickness will allow another round of heat to build, especially the farther you move inland from coastal areas.
Elevated areas of southern Monterey and San Benito county may see triple digit heat, along with portions of Contra Costa and Alameda county to the north on Saturday, which should be the peak of this round of heat.
