SYNOPSIS

01/103 AM.

Quiet weather with near seasonal temperatures will prevail the rest of the week. Breezy west to northwest winds will occur across portions of the area at times. Light rain showers are possible late Sunday into Monday. Dry and warmer conditions can be expected through next week.

LONG TERM (MON-THU)

01/102 AM.

For the extended, 00Z models continue to exhibit good synoptic agreement. At upper levels, low will move across Central California on Monday then a ridge will develop over the area Tuesday through Thursday. At the surface, moderate onshore flow will continue.

Forecast-wise, main "concern" in the extended period will be Monday as the upper low moves inland across Central California. With this passage, there will be some low chances of measurable precipitation (10-20%) with the best chances across the Central Coast. This low will be rather moisture-starved, so rainfall amounts, if any, will be only a few hundredths of an inch for most areas. However, the northwest corner of San Luis Obispo county could squeeze out around 0.10-0.20 inches as a worst case scenario. On Monday morning, there will be a decent chances of some patchy drizzle as the marine inversion deepens dramatically.

For Tuesday through Thursday, mostly clear and dry conditions are expected although there may be some continued coastal stratus and fog during the night/morning hours. With the ridge building overhead, a area-wide warming trend is expected. In fact by Thursday, temperatures will be topping out in the mid 70s to mid 80s.
