Looking at the weather pattern today, the one item that really caught my eye was a huge storm expected to move across the eastern Gulf of Alaska to western Canada Thursday into Friday. So let's take a quick look at the evolution of this storm.
The early afternoon satellite picture of the Pacific shows the beginnings of the storm southwest of the Aleutians out around the dateline.
The 12Z GFS shows that storm as modeled for 4 p.m. Tuesday, again just west of the dateline.
As the storm moves east, all models quickly intensify this storm, and by Thursday evening, we have a roaring 958 mb low in the eastern Gulf of Alaska west of southeastern Alaska and west-central Canada. This storm will then move inland later Thursday night.
Fishermen, take this as a warning. It is going to get very ugly to be out on the water Thursday into Friday in these heavily fished waters. Even though the cold front will weaken tremendously before coming into Washington state, large swells are likely to develop across the Northwest waters.
The first graphic shows wind waves and swells for Thursday evening.
The second graphic is the forecast for wind waves and swells for late Friday.
Another strong storm for this time of year is modeled for the Gulf of Alaska in the Sunday/Monday time period. This would be the storm that is now Typhoon Roke, headed to Japan.
As of the end of June there had been no named storms in the Eastern Pacific basin.
This is some serious and dangerous heat. Outdoor activity is just not at all recommended during the daytime.
A strong ridge of high pressure in the West brings the highest heat of the season so far to a large area.
Combine the cold with the wind and some precipitation and there is a real danger of hypothermia.
Any shower and thunderstorm can contain heavy downpours, heavy enough to cause temporary, low-lying ponding.
According to all long-range models, the warmest area in North America compared to average will be over the Northwest.
