SYNOPSIS
Upper level low off the British Columbia coast will continue to move southeast ending up over Western Washington Saturday. Weak front spinning out of the low moving through later this morning and early this afternoon. Low remaining in the vicinity Sunday before moving east Monday. Weak upper level trough over Western Washington Tuesday and Wednesday. Upper level ridge will try to build into British Columbia Thursday.

SHORT TERM /TODAY THROUGH SUNDAY/
Satellite imagery shows upper level low made good progress Thursday moving out of the Gulf of Alaska and is now west of Haida Gwaii. Weak front spinning out of the low off the coast. Doppler radar picking up the leading edge of the precipitation associated with the front just reaching the north coast at 4 am/11z. Skies still mostly clear over the southern portion of the area with mostly cloudy skies north.
Temperatures at 4 am were in the mid 40s to mid 50s.

Weak front reaching the coast later this morning moving through the interior late morning/early afternoon. Showers associated with the front along the north coast will spread inland over mainly the northern portion of the area this morning into the early afternoon. The front is pretty narrow so expect the duration of the shower activity to only be a few hours at best.
Temperatures aloft cooling during the day with the upper level low continuing to move towards Western Washington. This combined with increasing cloud cover will keep highs in the upper 50s to mid 60s.

Upper level over Vancouver Island tonight moving over Western Washington Saturday. Air mass becoming unstable with lifted indexes 0 to -3 and lapse rates plus 7 or 8C. Models have the 500 mb temperatures by 00z Sunday in the minus 26c to -28C range.
Little in the way of daytime heating Saturday but convective temperatures are only in the mid to upper 50s. Showers developing tonight as the low approaches with showers and a chance of thunderstorms Saturday for the entire area. Snow levels as low as 4000 feet so we could see some snow, will not really accumulate, on the higher passes, Washington, Chinook, Cayuse, that are open this time of year. Lows tonight in the mid to upper 40s. Highs Saturday in the mid 50s to lower 60s, a good 10 degrees below normal.

Low weakening Saturday night with the low drifting into Eastern Washington Sunday. Shower activity decreasing during the day Sunday. Chance for thunderstorms also decreasing Saturday night into Sunday. While lapse rates remain near plus 7C, lifted indexes go positive and the flow aloft becomes northerly on the back side of the low. It still going to be a cool day for Father's Day with highs only a couple of degrees either side of 60.

LONG TERM /MONDAY THROUGH THURSDAY/
Extended model solutions not showing as much consistency as earlier in the week. The general idea is northerly flow aloft on the back side of the low Monday with a very weak trough carving out over the area Tuesday and Wednesday then a weak ridge trying to build into British Columbia late in the week. The theme of all this is weak. Weak onshore flow in the lower levels, weak trough, weak ridge. Air mass remaining slightly unstable for most of the period. With none of the features being able to take over the pattern will keep a chance of showers for almost the entire period. Ensemble solutions leaning towards the ridge winning out in the latter part of next week for some dry and warmer weather. Slow warming trend with highs Monday in the lower to mid 60s warming to the mid 60s to mid 70s by Thursday. Felton

AVIATION
VFR. As a front progresses inland this morning, conditions along the coast will deteriorate to MVFR/localized IFR in low clouds and showers. A line of showers will move inland throughout the day with a 20% to 30% chance of thunderstorms in stronger showers that develop. Gusty outflow winds are possible near thunderstorms. Cloud cover will persist through Friday evening ahead of another round of showers and thunderstorms on Saturday, with forecast models hinting at convergence zone showers later on.
Surface winds will remain generally out of the S/SW throughout the day 12 kt or less.

KSEA...VFR this morning with increasing clouds ahead of an approaching front. Showers will pass the terminal between 18z/Fri- 03z/Sat, with brief MVFR conditions possible in heavier shower activity. Thunder is possible after 18z (25% chance) but confidence is not high enough to add to TAF. Thunderstorms look more favorable near KSEA on Saturday. S/SW surface winds roughly 8 to 12 kt persisting throughout the day.

MARINE
Although a weak frontal system will move across area waters throughout the day today, conditions will be fairly quiet for the next few days. The primary concern will be any thunderstorms that develop, with roughly a 20% to 30% chance of thunder activity in stronger showers that develop each afternoon through the weekend.
Heading into early next week, surface ridging offshore and lower pressure inland is expected to produce varying degrees of onshore flow. Seas are favored to remain between 4 to 6 feet through the period, with winds likely staying below SCA criteria throughout.
