(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kpqr 300317 afdpqr area forecast discussion national weather service portland or 817 pm pdt Mon may 29 2017 Synopsis A cooler weather pattern is in store for the rest of the week, with periodic chances for showers as a large trough of low pressure will remain over the NE pacific, and a series of disturbances lift NE across the pacific nw. Expect a little higher pops Tuesday, and then especially Wednesday night and Thursday morning. Short term Tonight through Thursday... Strong and relatively deep onshore flow remains over the pacific northwest this evening, and the clouds that cleared back to the coastal slopes of the coast range will spread onshore or reform again tonight and Tuesday morning inland into the west slopes of the cascades. Convection did develop over our oregon cascade zones this afternoon and evening and a threat will continue a few more hours. There is still some lightning to our south in southwest oregon. The model soundings and the models suggest that the threat of thunder will diminish overnight as this is not like our typical elevated convection scenario in the main part of summer following a hot day across the area, but nevertheless there could be a few showers spreading out to the northwest over the valleys and the coastal mountains overnight tonight into early Tuesday. Will stay with that idea for now. A broad low over the NE pacific will then push a decent short wave across the forecast area mainly the second half of Tuesday. Believe there is a better chance of showers at that point. Still, the main low level front stays offshore and it is the upper level part of the system that moves through. This disturbance will reinforce the onshore flow, and pressure gradients through the gorge will be stronger than those today. As a result, it will be quite windy through the gorge and over the cascade ridges Tuesday afternoon and evening. This will reduce the threat of any thunder Tuesday, though there is a small chance down toward willamette pass and north of mount adams Tuesday afternoon near the crest. Forcing for any showers in our forecast area for Wednesday is relatively weak. The next significant disturbance for our forecast area is Wednesday night into Thursday morning, and have bumped pops into the likely category for much of the area for that time period. The models indicate that there may be a weak frontal boundary moving through with that disturbance. Showers should start to ease late Thursday and Thursday evening. Tolleson Long term No changes. Previous discussion follows... Thursday night through Monday... Models in general agreement on swinging another shortwave through early Friday, as a longwave trough remains offshore. Wave is weak, and moisture is mainly low level, so will keep chances for showers with this feature limited to chance category, and will show a decreasing pop trend in the afternoon. |
Models remain in decent agreement showing shortwave ridging Fri night and early Sat for a bit of a break in the chances for showers. The next shortwave approaches Sat night and sun, but models begin to diverge in timing and intensity of the wave. GFS digs a deeper trough over the pacific NW sun, but this appears to be an anonymously deep and cool trough compared to GEFS ensembles. Similarly, the ec operational run appears to be weaker and faster than the ec ensemble mean, so overall believe something in between the two operational runs appears most likely. Will add in a slight chance for showers over the northern part of the forecast area from late Sun through early Mon for the passing trough. Aviation Typical late may early june pattern this evening. Coast is under ifr MVFR stratus while inland valleys are clear, and showers and few thunderstorms rumble over the high cascades. Weak south to southeast flow tonight may allow for a few showers to drift northwestward away from the cascades, but any threat of thunderstorms looks to remain over the crest and eastward. Now, with not much change to the marine layer that lies west of the cascades, will expect stratus to spread over most areas again tonight, though think will be mostly MVFR inland. Can not rule out occasional ifr with drizzle on the coast. Like Mon am, clouds will take until midday to early afternoon to break apart over the interior. Kpdx and approaches...VFR under clear skies this evening. But, will see increasing low MVFR stratus again late tonight between 08z and 11z. Like Mon am, will take until early Tue afternoon for stratus to break out toVFR conditions. Though 20% of a shower later tonight, will keep out of tafs. However, will showers and evening thunderstorms will continue in eastern approaches east of hood river until 07z. Rockey. Marine Quiet conditions continue with winds below 20 kt through Friday. Weak front moves through late Wednesday and another on Friday, doing little more than shifting winds to southerly starting Tuesday afternoon and keeping generally 5 to 15 kt southerly winds through Friday. Seas through Wednesday morning stay around 3 to 4 ft, building to 5 to 6 ft by Wednesday afternoon. Seas stay up around 5 to 6 ft through Friday. Next chance for winds above 20 kt will be next weekend as a broad upper-level ridge builds over the NE pacific and a thermal low sets up over northern california, generating gusty northerly wind pattern over our waters through next weekend. With gusty winds, may also get steep seas next weekend. -mccoy Pqr watches warnings advisories Or... None. Wa... None. Pz... None. Interact with us via social media: |
