March 30, 2020 – Threat of showers persists across far northern California thru Tuesday, otherwise dry and milder this week. Chance of precipitation returns over the weekend.
Discussion
Mostly cloudy skies linger across the region early this morning. Radar indicates that most precipitation has retreated to far northwest California. Current temperatures are milder compared to 24 hours ago across most of the area and range from the upper 20s and 30s in the mountains to the upper 40s to mid 50s across the Central Valley.
Generally drier and milder weather is expected this week as the storm track lies to the north across the PacNW. Light warm- advection precipitation will linger across the northern half of the forecast area today (generally north of I-80), then retreat further north on Tuesday. Breezy southerly winds on tap across the Sacramento Valley today.
Dry and milder conditions forecast Wednesday and Thursday with northerly surface flow returning. Highs will return to around average by Thursday.
Extended Discussion (Friday through Monday)
Models indicating next Pacific frontal system spreads precip into NW portions of the forecast area Friday afternoon into evening, then across most of the CWA Saturday. Deterministic models then diverge late Saturday as EC drops next offshore system into NorCal Sunday. Ensembles support this solution so POPS look to increase again Sunday into Monday as next upper low impacts the area.
