Marine Weather and Tide Forecast for Lynden, WA

SYNOPSIS
A frontal system will cross over the area this evening into Sunday morning, bringing widespread lowland rain, gusty winds, high elevation mountain snow, and high surf conditions. A brief break late Sunday before another wet and windy system moves into the area late Monday into Tuesday. Active weather continues through the end of the week with multiple systems passing into the area.

SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/
Brief dry conditions this afternoon across much of the area will be short lived, as a potent cold front crosses over western Washington this evening through Sunday morning.

We'll start to see an increase in lowland rain spreading along the coast this evening with widespread rainfall through in the interior tonight. Additionally, there is some instability with the aforementioned front, with a 20-30% chance of isolated thunderstorms, primarily along the coast. Could see a lightning strike or two in the interior, but less of chance of thunderstorms (10-20%). As rain spreads throughout the region southerly winds will increase over much of the area. Latest REFS guidance shows a 50-70% chance of wind gusts over 55 mph along for areas along the coast. Therefore, a High Wind Warning continues to remain in effect for areas along the coast.
Elsewhere, A Wind Advisory is out for interior areas, seeing gusts anywhere from 45 to 50 mph at times. Due to continued foliage on the trees for many locations, localized power outages can be possible. Furthermore, clogged storm drains may occur when the period of gusty winds overlaps with steadier rain this evening. Give yourself extra time if traveling this evening. The wind will peak during the overnight hours into early Sunday morning, before steadily decreasing late Sunday afternoon.

Seas will rise rapidly tonight into Sunday, building to 22 to 28 feet along the beaches tonight. A High Surf Warning remains in effect tonight for these areas. Those participating in razor clam digs should exercise caution, as large waves and strong winds will make for dangerous conditions for the clam dig.

Widespread steadier rain will transition into a more post- frontal shower environment through Sunday afternoon, with most of the shower activity focused on the North Cascades and Olympics. The primary concern shifts to high surf conditions along the coast on Sunday. Snow levels generally around 7000 to 7500 feet will fall to 4500 feet, for some accumulations in the higher terrain of the mountains. Shower activity will decrease over the interior throughout the day. High temps in the mid 50s.

A break in the weather Sunday evening before another system rolls right on in on Monday for another round of widespread rain and locally breezy conditions. Most of the QPF, once again is focused on the Olympics.

LONG TERM /TUESDAY THROUGH SATURDAY/
Latest ensemble guidance a bit shaky on timings and strength of upcoming systems. A steady plume of moisture looks to become more focused along Vancouver Island and parts of western Washington on Tuesday into Wednesday for more widespread rainfall, warmer temps, and breezy conditions. Most of the precip is aimed along the Olympics and North Cascades, with most of the interior seeing showers at times. Active weather continues with additional systems at the end of the week for more rainfall and breezy conditions. It seems like we have entered the active weather season this November!

AVIATION
The narrow cold frontal rain band passing brought heavy rain and low visibility to the Puget Sound terminal. Strong southerly surface winds with gusts 35 to 45 knots are peaking in the interior at this hour. Winds will peak during the overnight period and gradually ease through Sunday morning. Showers will persist through Sunday morning, tapering later in the day. A few isolated thunderstorms will be possible in any heavier bands of showers, but confidence in occurrence remains too low for inclusion in any TAF at this time.

KSEA...Wind gusts to 30 to 35 kt will linger tonight before easing early Sunday morning. Otherwise, expect mostly VFR ceilings with lingering showers through the overnight period now that the main rain band is through. A low (10%) chance of a thunderstorm overnight, but likelihood is too low for TAF inclusion.

MARINE
An active weather pattern will continue over the next several days as a series of frontal systems move across the area waters.

A vigorous frontal system associated with a deepening surface low offshore British Columbia will swing across the waters tonight into early Sunday. This system will produce a period of storm force wind gusts over the coastal waters and gales across the interior waters tonight into early Sunday. Seas will build to 22 to 28 feet late tonight into Sunday before gradually subsiding again Sunday night into Monday. Isolated thunderstorms will be possible in the wake of the system tonight into Sunday morning and may bring brief heavy downpours, lightning, gusty winds, and reduced visibilities to the area waters.

Weak high pressure will briefly build over the waters on Monday before another deepening surface low moving northward into the Gulf of Alaska pushes another front across the area waters Monday night into Tuesday. Seas will build back towards 16-18 ft on Tuesday and persist in this range into Wednesday.

Additional frontal systems will move through the waters mid to late week, likely bringing more rounds of widespread headlines to the area waters.

HYDROLOGY
River flooding is not expected through the next seven days.
Multiple weather systems moving through the area in the next week. While current precipitation forecasts are not expected to cause flooding, this will saturate soils and raise base flows that could bring a concern with storm systems by late next week.
