Area Forecast Discussion National Weather Service Seattle WA 339 AM PDT Sat Jun 12 2021

SYNOPSIS. Unsettled weather pattern will dominate Northwest US weather through early next week as a series of systems will bring periods of widespread rain to the region. Heavy rain will be possible at times this weekend as sub-tropical moisture encroaches upon the region. Showers and potential thunderstorms will persist through Tuesday before a warming and drying trend takes hold from mid week onward.

SHORT TERM /TODAY THROUGH SUNDAY NIGHT/. Scattered showers continue across portions of Western Washington at this hour. The latest water vapor satellite imagery shows an area of dry mid- level air starting to encroach upon the region from the southwest which will cause shower activity to start to wane as reach daybreak and progress through the morning. This is consistent with the latest HREF trends that suggest a fairly nice Saturday with a mix of sun and clouds into this afternoon. Expect temperatures to rise into the low to mid 70s as a result.

Later this afternoon and evening, the long anticipated arrival of the long fetch of rich sub-tropical moisture will arrive in Western Washington. Expect increasing clouds late this afternoon with rain quickly spreading across the southwest interior and Olympic Peninsula this evening. Rain will spread across the entire area by Saturday night and will persist through late Sunday night as the moisture band slowly traverses eastward. Given that mean flow will be southerly, banding is likely. Strong difluence aloft on top of a potential record setting moist airmass with dewpoints rising into the low 60s and precipital water values 2 to 3 standard deviations above normal for June (1.25" - 1.5") will set the stage for a very wet 24 hour period. Rainfall rates will be abnormally heavy at times - potentially up to 1"/hour rates at times. This will yield hazardous travel conditions as visibility will be poor at times and water will pond on roadways. Urban flooding will also be possible, especially in poor drainage areas. If you have travel plans Saturday night and Sunday, be sure to plan for plenty of travel time and use your low beam headlights when driving through heavy rain. The heaviest rainfall will likely fall in the southern Puget Sound region southward into the Chehalis Valley, where 24 hour rainfall totals will likely range from 0.5 to 1". Isolated spots of 1"+ are not out of the question, particularly where the heaviest banding sets up. The heaviest rainfall will likely fall from the south Puget Sound region southward into the Southwest Interior (Lewis/Thurston Counties and south), where 24 hour rainfall totals will likely range from 0.5 to 1". Isolated spots of 1"+ are not out of the question, particularly where the heaviest banding sets up. At this time, the higher probabilities for heavy banded rainfall reside in the aforementioned areas.

While heavy rain will be the greatest threat on Sunday, it is important to note several limiting factors with respect to thunderstorm potential - 1) Widespread cloud cover across the region will prevent adequate destabilization, 2) the atmospheric will be saturated through the column which is not conducive for adequate cooling aloft. That said, a rumble of thunder wont be out of the question in far southeastern portions of the area (southern Cascades) late Sunday as a subtle upper level disturbance traverses the region. That said, the highest chances for thunderstorm activity Sunday evening will remain east of the Cascades where the environment wont be modified by persistent heavy rainfall and cloud cover.

LONG TERM /MONDAY THROUGH FRIDAY/. Areas of efficient showers will persist through the day Monday with periods of heavy rain possible. PW's will begin to decrease late Monday into Tuesday as slightly drier air filters into the region once again. This will cause shower coverage to decrease late Monday afternoon, potentially allowing some sun to peak through the clouds.

Operational model guidance continues to indicate the large upper low off of the coast becoming negatively tilted late Monday into Tuesday before ejecting a shortwave trough across the region. While this remains a constant - there remains a fair amount of uncertainty in the forecast that will have an effect on thunderstorm coverage and strength. The placement of the shortwave will be important - if the energy is too far south and east, the potential for widespread thunderstorms will decrease rather significantly for western Washington. The timing is important as well - upper level energy arriving a little later in the day on Tuesday will allow for the atmosphere to destabilize, allowing for enough CAPE to support thunderstorms Tuesday afternoon and evening. That said, the potential for thunderstorms remains for Tuesday and will continue to monitor the important fine details in the model guidance leading up to the event.

Wednesday will mark the beginning of warming and drying conditions for Western Washington as the ridge axis over the Great Basin shifts westward. Expect to see temperatures rising back into the mid to upper 70s, potentially approaching 80 degrees to close out the week.

AVIATION. Southwesterly flow aloft with frontal system stalling over the area Sunday. Ceilings 4000 to 6000 feet this morning becoming aoa 10000 feet this afternoon. Ceilings lowering to around 2000 feet with local visibility 3-5sm in moderate rain 06z- 12z Sunday with the onset of rain.

KSEA . Ceilings near 4000 feet this morning becoming aoa 10000 feet this afternoon. Ceilings lowering to near 4000 feet around 06z tonight with light rain. Ceilings continuing to lower overnight down to around 2000 feet with visibility 3-5sm in rain by 12z Sunday.

MARINE. Another frontal system will move through the coastal waters tonight then stall over the inland waters Sunday. The front will dissipate Sunday night. Weak high pressure will gradually build into the region early next week for lighter winds across area waters.

Small craft advisory winds over the coastal waters later tonight through Sunday morning. Possible small craft advisory winds over the northern portion of the inland waters Sunday.

HYDROLOGY. Minor urban flooding and ponding of water on roadways will be likely Sunday as persistent moderate heavy rain is expected. Rainfall rates will reach or exceed 1"/hr at times, with areas from the South Puget Sound southward through Thurston and Lewis Counties likely seeing the highest rainfall totals. 24 hour rainfall totals of 0.5 to 1" is expected, with isolated areas over 1" possible (most likely in the aforementioned areas). River flooding is not expected with this system.
