New AVIATION, MARINE

SYNOPSIS
Issued at 1237 PM PDT Tue May 21 2024

Summer-like pattern to persist through Thursday. Temperatures are forecast to dip below seasonal averages by the upcoming weekend as an upper level trough impacts the region.

SHORT TERM
(This evening through Wednesday)
Issued at 1237 PM PDT Tue May 21 2024

The broad tilted upper level troughing pattern over California has brought some weak offshore winds over interior areas, causing some warmer temperatures and drier conditions. The offshore flow will help inhibit some of the marine layer from reaching inland tonight into Wednesday morning allowing for another blue sky morning for interior regions. On the other hand, the weak onshore flow along the coast will bring some low clouds along the coastal areas, especially near Monterey Bay and Salinas Valley tonight. Models show interior regions will be on the drier side this evening with minimum relative humidity values between 14-30%.

Overnight temperatures are relatively the same as last night with minimums in the mid to upper 40's to low to mid 50's. Some isolated areas will see a slight increase 2-3 degrees higher. Temperatures will start to trend cooler on Wednesday, but still will be relatively warmer than usual with inland max temperatures in the low 80s to high 70s, as coastal areas will see temperatures in the upper 50s to 60s. The onshore flow along the coast will increase on Wednesday, which will help increase some relative humidity values between 20-55%.

LONG TERM
(Wednesday night through next Monday)
Issued at 1237 PM PDT Tue May 21 2024

The low pressure system that sits in the northwest, will drop south a bit on Thursday and will move across the Pacific northwest over the weekend, which will bring stronger onshore flow and cooler temperatures. Thursday will start to see max temperatures in the mid 70s inland and upper 50s to 60s along the coast. Friday through the weekend, max temperatures are expected to drop between 5 to 7 degrees below average over the weekend with mid 50s to low 60s coastline and upper 60s to low 70s inland. With the stronger onshore flow, expect the gloomy mornings pattern to continue along the coast, with slow clearing in the mornings. Ensemble models show no impactful precipitation associated with this trough as it moves through our area this weekend, but if precipitation does occur this weekend, expect the best chance to occur near the coast. On Sunday into Monday, a weak ridging will develop over our area bringing back some slightly warmer temperatures.
