SYNOPSIS

Showers taper off early this morning. Ridging fills in behind the low with warmer temperatures and clearer skies by mid week.

DISCUSSION

A drier weather pattern starts today as showers taper off and move out of the area. High pressure will build through late week, bringing warmer than average temperatures but otherwise dry, seasonable, and mild weather. By Wednesday most interior valleys are forecast to be in the high 70s to low 80s. There is chance for the marine layer to finally clear out Wednesday, but this will likely return by late week. Confidence is increasing in much warmer interior temperatures this weekend into early next week as strong high pressure builds over the area. NBM is showing high probabilities for many of the interior valleys to see high temperatures over 90 by Sunday. Chances for over 95 are around 20- 40% for the warmest valleys. There is even a low-end chance (20%) for high temperatures over 100 degrees by Monday of next week for the valleys of southern Mendocino and Lake.

AVIATION...(6Z TAFs)

MVFR to VFR conditions are being observed at the terminals. Generally IFR to MVFR ceilings are expected at all terminals through the early morning. Inland areas are expected to see lifting and clearing as drier conditions move in. Coastal areas may see some lifting and partial or temporary clearing, with MVFR to VFR conditions likely by the afternoon. Breezy north winds of around 10 kts or lower are possible this afternoon.

MARINE

Light southwesterly winds are expected to become more northwest and eventually north today. Winds will generally be light at around 5 to 15 kts. Seas are dominated by a northwest swell around 7 feet at 13 seconds. There is also a second wave group of around 3 feet at 8 seconds. The waves remain dominated by a 3 to 4 foot wave at 12 seconds and a 2 to 4 foot wave around 5 to 8 seconds. The winds are generally expected to remain around 5 to 15 kt out of the north through the workweek. Late in the week a system moving by to the north may briefly switch the winds to the west or southwest. Over the weekend, high pressure returns and near gale to gale force northerly winds are expected to return. The waves are expected to remain fairly small, around 3 to 5 feet at 10 seconds. A new swell is expected to build to 4 to 6 feet at 14 seconds on Wednesday. MKK
