New UPDATE, MARINE

SYNOPSIS
Issued at 1237 PM PDT Sun May 19 2024

Typical summer-like pattern to persist throughout the first half of the week. Temperatures are forecast to dip below seasonal averages by late week and into the upcoming weekend as an upper level trough impacts the region.

UPDATE
Issued at 907 AM PDT Mon May 20 2024

Satellite imagery shows stratus starting to clear across the lower elevations of the Central Coast, a trend expected to continue through the rest of the morning. Sunshine is expected across the region this afternoon with stratus impacts mainly confined to the coastal regions tonight, expecially near Monterey Bay. No changes to the forecast at this time.

DialH

SHORT TERM
(Today and tonight)
Issued at 307 AM PDT Mon May 20 2024

Stratus coverage is less widespread tonight with the Fort Ord profiler showing the marine layer nearly mixed out. That being said persistence is key and stratus has developed along the coastline of the Monterey Bay and San Francisco Peninsula. Similar to the past few days, stratus coverage is expected to dissipate by mid-morning with sunny skies through the afternoon. Gusty to gale force winds over the coastal waters should keep the marine layer well mixed and see stratus coverage limited to the coastline for the next few days.
There is a low potential (less than 10%) for drizzle in coastal areas tonight with up to trace accumulations possible.

Inland temperatures will remain seasonal to slightly above average with highs in the mid to upper 70s. A few locations across the North and East Bays may see highs reach the low 80s. Along the coast, stratus will continue to limit daytime warming with temperatures slightly below average in the upper 50s to low 60s.

LONG TERM
(Tuesday through Sunday)
Issued at 307 AM PDT Mon May 20 2024

Over the coastal waters, gustier, northerly winds continue through the end of the week. The marine layer will stay fairly well mixed for the next few days with stratus confined along the coast and minimal stratus impacts inland. Slight warming trend through mid- week caused by weaker onshore flow and increasingly northerly winds inland remains on track. Ensemble guidance and the NBM are in agreement that Tuesday will be the warmest day this week with temperatures reaching into the mid 80s. There is fairly good agreement that high temperatures will stay in the mid 80's but NBM 90th percentile does show a few sites in the North Bay reaching the upper 80s (88-89 degree range). In comparison to yesterday's forecast, Tuesday high temperatures have increased by a few degrees from the low to mid 80's to predominantly in the mid 80s. Minor heat risk is expected throughout most of the Bay Area and Central Coast (Santa Cruz Mountains, Salinas Valley, portions of the Monterey Peninsula) Monday through Wednesday as slightly above average temperatures persist. People who are incredibly sensitive to heat should take precautions while outdoors and remember to drink plenty of water.

Temperatures will cool down by the late week as a stronger upper level trough moves inland Friday/Saturday. This systems looks fairly dry with ensemble guidance indicating very low chances of accumulating precipitation with it. CPC guidance continues to indicate predominantly below average temperatures and slightly above average precipitation through the end of May.
