Record heat through early next week; Watching Lidia this weekend
August 31, 2017; 7:12 PM
We have a couple things to watch for through the weekend and into next week across the West.
More hot weather is expected through the weekend and into early next week across the Pacific West as an upper-level ridge dominates the weather pattern.
An offshore flow will largely continue across Southern California heading through Saturday which will make for very warm weather at the beaches and even hotter weather inland.
Many places in the Pacific West will challenge high temperature records over the coming days so this will be some intense heat yet again.
For Southern California, the hottest days coming up will be Friday and Saturday. By Sunday, temperatures are likely to fall a few since there will be an increase in moisture (more on that later) but they could easily jump right back up later in the week.
In the Northwest and British Columbia, the hottest days are more likely early next week. The ridge aloft is expected to bulge more to the north into British Columbia in response to a deepening trough near the Gulf of Alaska.
For places like Portland and Seattle, each day will be hot, but Monday and Tuesday (maybe even Wednesday), will likely be when afternoon temperatures are at their highest.
As of right now, our forecast calls for record highs in Portland on Sunday, Monday, Tuesday, and Wednesday. Impressive!
Remember, take the heat seriously! Try not to spend much time outdoors during the middle of the day and drink plenty of water. If you are outside, make sure to wear lighter colored clothing.
Folks should also be mindful that there will also be an elevated fire danger.
Aside from the heat, we will also have to keep an eye on Tropical Storm Lidia as it progresses north across Baja California through Sunday.
The current forecast track takes Lidia north across Baja California through Sunday morning, then hooks westward through Tuesday moving away from Baja California and Southern California. This matches up with most weather models.
However, it is important to note that the GFS weather model is much farther north with the track and actually brings Lidia, which will be a tropical rainstorm by Sunday, into Southern California. If this were to occur, then Lidia's moisture would play a much bigger role on Sunday.
However, this model is the furthest north and is the outlier at this time and the expected track at this time is shown in the graphic.
Regardless, some of Lidia's moisture will make into Southern California on Sunday and will bring an uptick in clouds and thunderstorm activity in the mountains and Upper Desert. As mentioned above, this will help bring a few degrees of cooling to the region.
