The stormy weather in the Northwest continues. Between Wednesday night and Friday another three impressive storms will likely move through. Each will bring a period of heavy rain and mountain snow to the Cascades on west along with strong winds especially for coastal areas. The first storm will bring the heaviest precipitation and wind from northwest Oregon through Washington. The next two storms will aim the heaviest precipitation and the strongest winds in Oregon. The third storm is likely to bring a cold front south through central California Saturday with a period of rain for the Bay Area on east with a round of heavy snow and strong winds in the Sierra from just south of Tahoe on north. Farther south, precipitation will diminish to showers or lighter amounts of mountain snow. No precipitation is likely in Southern California.
The satellite picture from early Wednesday afternoon shows the first two storms.
The first is centered around 50N and 145W with an impressive cold front stretching out ahead of it. The second storm is developing south of the western Aleutians with the upper-level disturbance out to west of the date line and north of 40 north.
The rain of late and the expected rainfall over the next few days will push streams and rivers higher and higher. There is the threat from flooding and mudslides. In addition, the heavy snow accumulations in the Cascades will affect travel and bring increasing danger of avalanches.
Here are the accumulated precipitation amounts from this morning through the daylight hours of Saturday. These totals are very impressive.
And if that was not enough, additional storms are likely into next week.
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.
