Synopsis
Mild weather with clear skies may get an interlude of stratus tomorrow. Frost for low lying areas, particularly the interior, are possible overnight.

A low pressure system continues over the great basin while high pressure builds over British Columbia. The low will continue east in the next few days as diminished ridging settles in the CWA. The deformation of pressure will aid in offshore flow, continuing clear skies and dry conditions. Lighter winds, warm air aloft, and low level moisture will play a significant role in stratus and low cloud development in the near future. Low near the coast may be expected tomorrow as model soundings and HREF show considerable stratus. Mendocino and Humboldt coast could get socked in until the Thursday evening. Frost is expected overnight for Humboldt, Trinity, Mendocino and Lake interior valleys and some coastal areas. A frost advisory is in place from 1 to 9am PDT.

Friday through Sunday ensembles are in good agreement that inland temperatures will warm some each day with highs reaching the upper 80s by Sunday. At the coast each day the potential for stratus will increase as the high pressure builds and the flow weakens. As the temperatures aloft warm the threat for frost each morning will diminish.

As the previously mentioned ridge starts to break down, this will impact how quickly temperatures cool and whether or not we receive precipitation. A number of the ensembles bring a small amount of rain to the area Monday, but is not certain at this time. /EYS /MKK
