Snow is easing off over the north so warnings should be gone by early morning. Chance of flurries or showers remain for most of the interior today.

Winds currently picking up over the inner south coast. Guidance is marginal for Vancouver warning.

Extended range has changed for the worse with more cloud for south coast than earlier runs. Other models are in fairly good agreement. SCRIBE 30% POP for Thursday may be overdone.

Northwesterly gales for most of the coast today are expected to ease off this morning, except for off West Vancouver Island where gales will persist into tonight. Westerly gales through JDF are expected to ease slightly today, before picking back up to gales this afternoon. A ridge building over the coast will maintain northwesterlies through the short range period, but wind speeds are expected to graduallye ease. The next system will approach the North Coast wednesday, and has the potential to bring storm force southerly winds to sections of the north coast. However, the GEM GLB was the strongest with this feature, so have left strong gales for now.

Northwest wind gusts up to 38 kt observed at YVR and the strong gusts are expected to last until 21Z, so kept wind warning going on. A weak upr disturbance may bring isolated showers to south coast inland sxns this evening, then the clearing trend overnight may give chance to frost for some south coast regions. Sunny skies are expected over much of the coast tomorrow.

Long Range Discussion: Models are in fairly good agreement over the long range. Low pressure system over Gulf of Alaska on Wednesday will track across the Yukon Wednesday night thru Thursday. Associated frontal system will grive precip to the North Coast Wednesday and Thursday. GFS looks to be the driest model on Thursday, with GLB having a bullseye over North Vancouver Island, while NAM has the bullseye over the Central Coast. The ridge tilts Northwards on Thursday night, keeping the North Coast dry through Friday daytime. However, models agree on another low moving into Alaska on Friday night, giving precip to the North Coast. Ridge will keep the south coast dry thru the weekend with temps in the mid to high teens for the weekend.
