SYNOPSIS

01/838 PM.

Quiet weather with near seasonal temperatures will prevail through at least Saturday. A cooling trend will begin Sunday and there is a chance of drizzle or light rain showers late Sunday through Monday night. Dry and warmer conditions can be expected starting next Wednesday.

LONG TERM (TUE-FRI)

01/205 PM.

Cool conditions will continue into at least Tuesday as models are indicating the upper low finally getting nudged east. Although most of the ensemble solutions slightly favor Monday as the "best" chance of any precip, Tuesday may actually have a higher chance due to higher moisture content (increasing to 0.8") and slightly better instability with low passing overhead. This isn't really reflected in the current forecast mainly due to lots of uncertainty with the precise track of the low, but certainly can't rule out some scattered light showers Tuesday.

A weak high pressure ridge is expected to move over the West coast by later Wednesday and last more or less into next weekend with warming temperatures, possibly getting close to 90 in the warmer valleys by Friday.
