Marine Weather and Tide Forecast for Hobart, WA

SHORT TERM /TONIGHT THROUGH WEDNESDAY/
Southwest flow aloft will allow for slightly warmer conditions today, with highs on track to reach the upper 60s to low 70s across much of the region today. Clouds will slowly increase along the coast tonight as the next system approaches.

Onshore flow will continue Monday as a weak and mostly dry front pushes inland. Most of the region will see little more than increased clouds and a few sprinkles, with clearing skies in the afternoon after the front passes. Temperatures will peak again in the upper 60s to low 70s for most inland areas, with highs in the low 60s along the coast.

Another weak front will lift north across western Washington on Tuesday, bringing increased clouds and chances of showers along the coast. Overall rainfall amounts will be light, with most areas expected to only see a couple hundredths of an inch of rain. Afternoon highs will again be in the upper 60s to mid 70s across the interior and low 60s along the coast.

A cold front will shift inland late Tuesday into Wednesday, bringing in a quick shot of light rain and cloudy skies.
Precipitation amounts will be light, especially south and east of the Puget Sound. The bulk of the moisture will be focused over the Olympic Peninsula and North Cascades, where up to a quarter inch of rain is possible. A majority of the lowlands will see accumulations of a few hundredths. Temperatures will once again reach the upper 60s to mid 70s across the interior and low 60s along the coast.

LONG TERM /THURSDAY THROUGH SUNDAY/
A cutoff low will approach the coast towards the end of the week, with light post frontal showers lingering over higher terrain on Thursday. The low pressure system will shift inland on Friday throughout next weekend, bringing in the most notable precipitation of the forecast period alongside breezy winds and cooler temperatures.
At this time, rainfall across the lowlands look to range between a quarter to a third of an inch of accumulation, with an inch or more of liquid over the Olympics and Cascades. This cooler storm system will also bring snow levels down to 5000-6000 feet, resulting in some light snow accumulations over the higher peaks.
Over the weekend, temperatures will peak below normal in the low to mid 60s for much of the region.

AVIATION
VFR conditions expected to prevail for the TAF period for all terminals, with the exception of KHQM. Cloud cover will increase overnight. Mid-to-high level cloud cover will impact the interior terminals, while low cloud cover will be limited to coastal terminals. Ergo, MVFR ceilings are highly likely along the coast starting around 9Z-12Z Monday, with the potential to drop down to IFR (30-40% chance). Conditions expected to improve along the coast to VFR after 18Z-20Z.

Northwesterly surface flow will turn more northerly overnight this evening along the interior terminals, with winds more westerly along the coast. Breezy westerly winds expected again along the Strait of Juan de Fuca this afternoon/evening.

KSEA...VFR conditions will persist through the TAF package. Mid-to- high cloud cover will increase overnight. Low clouds are not expected to impact the terminal, with guidance also having a low chance of MVFR ceilings (10-15%). Northwesterly winds (6-8 kt) will become more northerly overnight (4-6 kt). Southwesterly flow returns Monday between 18Z-20Z.

MARINE
High pressure over the coastal waters today will maintain northwesterly. A weak cold front early Monday morning will bring southwesterly winds, with winds turning more southerly Tuesday.
Generally calm conditions for the coastal waters as additional systems traverse the waters throughout the week.

Diurnally driven pushes of westerly winds down the Strait of Juan de Fuca will occur during the evening hours over the next several days with varying degrees of intensity. Today's push looks to remain below small craft strength, with sustained wind speeds around 15-20 kt for the central and east Strait. In addition, may occasionally see some gusts up to 25 kt. However, with probabilities being 20% or less in exceeding 21 kt across the Strait, decided to hold off on issuing a Small Craft.

Seas across the coastal waters will generally remain between 3-4 ft today, increasing to 4-6 ft on Monday. By midweek, seas will subside to 3-5 ft. A system at the end of the week will allow for seas to build towards 5-7 ft by the weekend.
