TT-SEA

It definitely is now.

Canadian and GFS are much farther south with the weekend ULL. I like to see that.

Probably should.

GFS is way deeper with the Sunday trough. I like that. Too tired to make it to the ECMWF tonight. Not ignoring it if the heat wave disappears on that run... just sleeping.

Most everyone gets some rain tomorrow... except the new desert areas of Olympia and parts of Vancouver Island. http://www.atmos.washington.edu/wrfrt/data/current_gfs/images_d3/ww_pcp24.36.0000.gif

Clearly the inversion is gone because SEA went from 59 at noon to 76 at 5 p.m. Might still go a little higher. It will be interesting to see if it returns on Wednesday and Thursday or if there was just something different about the weekend trough.

Inversion appears to have broken in Seattle... temps warmed up quickly and the haze has cleared. Still sort of lingering to the east against the mountains though.

Welcome to central King County! We get all kinds of action here. Sometimes its annoying and sometimes its really fun. Summer rain and convection in a c-zone is fun. So is c-zone snow. I would LOVE an inch of rain tomorrow.

Hazy... looking forward to rain and an air cleaning tomorrow.

Still looks too far north and too weak to bring rain. Probably just sunny, pleasant days for most of the area.

Latest update... Nina looks more organized. http://www.ospo.noaa.gov/data/sst/anomaly/2016/anomnight.8.1.2016.gif

12Z ECMWF shows a heat wave out here next week while its cooler in Minnesota. Figures. I wanted cool and rainy while we were gone because we can't be watering. That massive vortex over AK has heat wave written all over it for the PNW. http://stream.ecmwf.int/data/atls02/data/data01/scratch/ps2png-atls02-95e2cf679cd58ee9b4db4dd119a05a8d-96ejB3.png http://stream.ecmwf.int/data/atls09/data/data01/scratch/ps2png-atls09-95e2cf679cd58ee9b4db4dd119a05a8d-IEjmub.png

Duvall and then also Jim's area are last to clear on days like this... clouds get pushed east and bank up against the hills there.

Side note... the ECMWF surface maps are BY FAR the best model in handling these inversions. It beats the WRF every single time. If the WRF shows sunny and the ECMWF shows cloudy then it will be cloudy here.

12Z ECMWF insists on a major c-zone tomorrow morning into early afternoon over King County. It shows some impressive rainfall in that time from Seattle to Snoqualmie Pass. Also shows back to sunny everywhere by Wednesday afternoon and Thursday looks spectacular.

You can see the seam along the I-90 corridor.

Very typical break up... a seam forms along I-90 and splits the low clouds to the north and south. Then it all clears from the west. Probably has to do with the hills running west to east along I-90.

And now the live shot from Seattle...

Here was the shallow fog layer moving into Seattle this morning at 6 a.m. It was totally clear all night until this point.

Always happens slower than models show. WRF thinks all the low clouds are gone at 11 a.m. http://www.atmos.washington.edu/wrfrt/data/current_gfs/images_d3/intcld.06.0000.gif

Clouds are dissolving now over the Seattle area. Sun should mix it out and the front coming in should help. Very ripe for a evening high at SEA again today... we will see.

Models do horrible with that type of inversion. Really shallow too since Seattle totally fogged in around 6 a.m.

Its been totally sunny here all morning... clouds stopped just to the west. Now breaking up pretty good even over Seattle. Low clouds patches will shrink from west to east up here.

No... ita a great cam where you can pull up images from any day. Very useful.

SEA is stuck in a cold inversion. And GFS MOS shows 67 tomorrow.
