... Much cooler weather through Saturday... ... First widespread frost expected across the interior valleys Saturday morning... A deep trough of low pressure will drop into the Great Basin this weekend... and bring significantly cooler temperatures to northwest California. A dry air mass in combination with clear skies... light winds and longer nights will result in early morning temperatures well below normal for the valleys and along the coast Saturday morning. The first widespread frost of the season will be possible... with early morning temperatures expected to fall into the upper 20s to mid 30s. Even though the air mass is expected to warm on Sunday... it will still be quite cold in the morning. Those wishing to protect temperature sensitive vegetation should consider those preparations at this time and keep informed of later forecasts and potential advisories in subsequent days. 230 PM PDT Fri Oct 10 2008 ...
