Area Forecast Discussion . UPDATED National Weather Service Portland OR 949 AM PDT Fri Aug 14 2020
Updated aviation discussion
SYNOPSIS. Temperatures start heating up across the Pacific Northwest today as an upper level ridge builds into the region from the Great Basin. Northerly flow will become breezy this afternoon and evening, further drying out the forecast area and elevating fire weather concerns. The sharp warming trend continues Saturday with high temperatures likely to reach 100 degrees for some inland valleys and potentially as high as 90 degrees for some coastal areas. Hot weather will continue into Sunday, then onshore flow will gradually increase for a slow cooling trend early next week.
SHORT TERM. Today through Sunday . Say goodbye to cool weather this morning, as we sharply transition into a very hot and dry weather pattern today and Saturday. The upper trough which had kept the region mild has moved east, already approaching the Dakotas. This is allowing a hot upper level ridge of high pressure to build into the region from the Great Basin. The air mass aloft will warm quickly today as a result, from around +12 deg C early this morning to +17 to +19 deg C by early afternoon per the 09z HRRR run. Additionally, thermal low pressure is strengthening along the coast near the OR/CA border, inducing more of a northerly component to the low-level flow.
The increasingly offshore flow will likely take full advantage of the warm air mass, mixing down dry adiabatically to the surface from 850-900 mb and allowing high temperatures to approach 90 degrees for our inland valleys this afternoon. The dry northerly flow will also result in very low RH possibly down into the teens Coast Range eastward this afternoon, while north winds gust 20-30 mph in the Willamette Valley and across the Coast Range ridges. The combination of very warm, dry, and breezy conditions are elevating fire concerns. As such, a Red Flag Warning remains in effect for the Fire Wx Zones 603/604 this afternoon and evening, which looks to be in good shape based on latest guidance.
Overall, we made very few changes to the high temperature forecast either Saturday or Sunday, as it looks to be in good shape and in line with latest guidance. The sharp warmup will continue into Saturday, aided by downsloping low-level northeasterly flow which will even heat up coastal areas. Strongly considered adding the North Coast to the Heat Advisory as a result, as places more than a mile or so from the beach could reach the 90s if offshore flow is persistent enough. However, after looking at latest high-res guidance such as the 1.33 km UW WRF and 4 km UW high-res ensemble, it appears offshore flow will not be strong enough to hold off a shallow sea breeze much longer than midday Saturday. Still would not be surprised to see KAST and KTMK reach 90 degrees, but this would only be for a couple hours - not really long enough for significant impacts. Coastal areas should cool off nicely Saturday night as a southerly wind reversal develops along the coast with gradually increasing stratus.
Any relief the coast sees Sat night won't extend very far inland, and inland areas will remain very warm and dry overnight. Hotter urban areas such as the Inner Eastside of Portland may only see low temperatures reach the lower 70s Sat night, offering little overnight relief for those without access to air conditioning. More rural valley locations could see a little more overnight relief due to more efficient radiational cooling, but this will only be enough to get them a few hours with temps in the 60s. Overall, the existing heat and fire wx headlines look good and will make no changes. Inland valleys will likely see back-to-back days with highs near 100 degrees and the above-mentioned very warm night in between. The heat will induce thermal low pressure to build north across western Oregon, leading to hot, dry, and unstable conditions each day which could pose control problems for any current or existing fires in the area. The instability may be enough to trigger a thunderstorm or two in the Cascades Sunday afternoon as moisture slightly increases in southerly flow aloft. Further fire wx information can be found below and in the Fire Weather Planning Forecast (FWFPQR).
Interestingly, some potential for smoke from the Mosier fire to drift westward Sat and Sat night, affecting areas in the Hood River Valley, western Columbia Gorge, and parts of the eastern Portland metro area. But, this will depend on status of the fire by that timeframe. For now, will put areas of smoke in forecast. Weagle/Rocket
LONG TERM. No Changes Previous discussion follows. Sunday night through Thursday . Upper flow is southerly Sunday night into early Monday. Models still showing some weak instability drifting northward Sunday night, though best instability is east of the Cascades. But, even so, can not rule out a thunderstorm over the Cascades Sunday night. Will keep 20 pct PoPs for such in the forecast. But, air mass is quite dry, and would not be surprised if just end up just seeing some mid-level clouds with a few virga over the Cascades at that time.
Weak surface high will build along the coast Sunday night and Monday, giving some light onshore flow to the lower elevations. but, looks like this will be a rather shallow marine layer, with only a slight relief for inland areas on Monday. Will trend high temperatures back to the 60s and 70s along the coast, but lower 90s still a good bet farther inland. At least trend is starting, and will see slow cool down through rest of next week, with highs generally in the 80s inland, and 60s on the coast. /Rockey.
FIRE WEATHER. No changes Previous discussion follows. The breezy north to northeast winds in parts of the region, combined with low humidity, will join forces to boost potential of fire spread on Friday afternoon and evening. Highest potential will be in the Willamette Valley and nearby areas of the east slopes of the Coast Range from about McMinnville southward. Good bet will see winds gusting 20 to 30 mph along with afternoon humidity down to 18 to 25 percent in those areas. As such, will upgrade Fire Weather Watch to a Red Flag Warning for those areas. Rest of the region will be dry and locally breezy, but think not as windy. Even so, finer fuels could carry a loose fire.
Though northerly winds ease Friday night, will maintain very warm and dry air mass for Saturday and Sunday. The elongated ORCA low, aka the thermal low of southwest Oregon, will sit over the Coast Range on Saturday and Saturday night, then slowly shift eastward on Sunday, before reestablishing itself east of the Cascades on Monday. Models continue to highlight enhanced instability with high haines air. So, have posted a Red Flag Warning for dry and unstable conditions over the Coast Range and Willapa Hills on Saturday, and essential I5 Corridor and Willamette Valley eastward for both Saturday and Sunday. Main concern with dry and unstable conditions is that with dry fuels, the air mass will be supportive for any existing or new fire to becoming plume dominated. /Rockey
AVIATION. VFR the next 24 hours with mostly clear skies. Marine stratus looks to remain offshore, but could see some stratus along the coast Saturday morning. Given the dry air mass aloft conditions will not be impacted. Gusty northerly winds around 20-25 kt possible across the region through midnight tonight.
KPDX and APPROACHES . VFR the next 24 hours with clear skies and gusty northwesterly winds to 20 kt possible between 20-04Z. /64
MARINE. High pressure will remain over the waters through Sat, with thermally-induced lower pressure over the south Oregon coast. Winds have slowly begun to increase through the morning and should become 15 to 20 kt with gusts up to 25 kt by Fri afternoon. Strongest winds will be observed in the central waters out to 60 NM. Winds will likely remain elevated to small craft level winds through Sat afternoon. The central waters are expected to drop off first with the north Oregon/south Washington waters persisting into very early Sun morning. On Sun, a disturbance will move north from the east Pacific. This disturbance will cause winds to reverse and become southerly. This direction shift is expected to last through Tue morning when high pressure builds back in.
While the main swell will be 4 to 6 ft through much of the period, an increased wind wave component will likely cause seas to build slightly this afternoon. This pattern will repeat on Sat afternoon - mainly in the central waters. Seas will then ease to near 3 ft with a 10 second period on Mon where they will persist through the rest of the period. -Muessle
