Gusty winds ovnite as an upper trough inland compressed the flow aloft over SWBC #YVR. Winds decrease next few hours as a ridge slowly builds onto the coast. Variable skies w/some higher clouds arcing over the top of the upr ridge offshore. Same thru the weekend. Breezy Sun

At this point, models suggest Sept will end on the dry side for the LM. 16.5 mm for YVR Sea Island so far this month. Normals are 51.9 mm at month-end and nothing that could produce, even cumulatively, 35 mm is in sight.

Salmon-y-pink sky near sunrise #YVR

That sunrise #YVR was due to ACC. A weak trough extending SW from a system moving thru N-Central BC may bring a few "surprise!" light showers in the next hour or 2 #YVR. Nada in the mdls. After that vrbl skies and dry until Sun PM w/a few more light shwrs. Damp E winds tmrw.

Earlier this week ensembles suggested that #YVR was going to stay on the dry side of an offshore upr trough. That's no longer the case, with mdls shifting the trough E and putting SWBC smack into the storm track after Wed. So anticipate rain and potential strong wind later nxt wk

Although some storminess looking increasingly likely later next week #YVR, uncertainties remain, as the system currently projected to be a major system off the W coast nxt Thu/Fri is currently a wave (ex TD-14-Pulasan) btn Srn Japan and S Korea.

SWBC under a SW flow w/an upr low Xing the BC N cst this AM. Shwrs/E wind dvlp erly PM #YVR as a trailing trof tracks inland. Vrbl skies Mon as a ridge builds overhead. Mainly sunny, warm Tue. Rain/wind by erly Wed as a sharp trough (dvlpg now 45N 170W) digs across the coast

Trend in the Euro Ensemble continues w/a stronger trough further to the E for later in the week but there's still a lot of variance in the development of surface features, so stay tuned #YVR

In spite of a building upper ridge over SWBC this evening and 500 hPa heights moving past 576 dm, there's still a few misty sprinkles about. Quillayute (UIL) sounding shows a daily record amount of water vapor in the local atmosphere.

Despite 580+ heights over SWBC (normally a guarantee of a dry warm day even in late Sep), the sheer amount of water vapour in the sounding producing warm-process rain #YVR. Second highest level ever recorded, since Sep 6, 1957. Should slowly dry this AM as the ridge builds to 585

Our new article in Nature's Scientific Reports shows that the latest climate models project even larger increases in persistent summer weather extremes:

With a 19° temperature and a 17.5° dewpoint it’s really soft out here #YVR. Eerie in a way
