We'll start today's update with a look at the downright insanely hot temperatures in the Pacific Northwest.

According to the National Weather Service in Portland, Oregon, a new all-time record high temperature was set on Sunday at 112°F, which broke Saturday's all-time record high temperature of 108°F. Before this past weekend, the warmest temperature on record was 107°F set in July of 1965 and in August of 1981.

Could this be the third day in a row that the all-time high temperature is broken? Our high-resolution temperature map (Maps > Temperature) shows the scene on Monday afternoon and it will be yet another blazing day.

The OpenSummit hourly forecast for Seattle, Washington has a high temperature of 106°F on Monday, while the forecast for Portland, Oregon tops out at 115°F. This is scary hot for an area of the country where air conditioning is not common.

Keep an eye on the Twitter accounts for NWS Seattle and NWS Portland to see just how high the temperatures climb on Monday afternoon.

Elsewhere across the Western United States, cool and active weather in the southern Rockies will continue to help reduce the wildfire threat through the upcoming week, while some moisture finds its way into the West Coast and the northern Rockies later in the week.

Forecast for Monday, June 28

The main story for Monday will be the record temperatures in the Pacific Northwest but we can't forget about the exceptionally low temperatures in New Mexico. Taos will only reach into the mid-60s on Monday afternoon.

New Mexico will also be the focus for widespread precipitation on Monday, especially into the southern half of the state. Colorado will receive limited thunderstorm activity on Monday afternoon, mainly focusing on the higher elevations along the divide.

Forecast for Tuesday, June 29

Not much change for temperatures come Tuesday as the tale of two stories is featured on the map below. Above-average in the Pacific Northwest and below-average in the southern Rockies.

Increasing moisture in the atmosphere across the Southwest and southern Rockies will fire up afternoon thunderstorms on Tuesday. The San Juan mountains will receive the best coverage in Colorado, while the bullseye continues across the eastern half of New Mexico.

Forecast for Wednesday, June 30

The ridge of high pressure that has been dominating the Pacific Northwest will gradually begin to shift north and east on Wednesday. This will help to bring some relief to areas along the coast, while areas in eastern Washington, northern Idaho, and western Montana receive the bulk of the heat.

This shift in the pattern by the middle of the week will help to usher in more moisture for Colorado, New Mexico, Utah, and Arizona. The California high country could also get in the action, though coverage will likely be limited to the highest elevations.

Forecast for Thursday, July 1

Much of the same is expected on Thursday. Blazing temperatures will continue across the Pacific Northwest and the northern Rockies, while cool and active weather focuses on the southern half of the Rockies.

For precipitation on Thursday, we'll likely be looking at another day of scattered afternoon thunderstorms from east to west across the Western United States, with the higher elevations receiving the bulk of the coverage.

Forecast for Friday, July 2

Am I beginning to sound like a broken record? Hot in the north, cool in the south. That will remain the case on Friday and into the holiday weekend. I'm loving this weather for my home in the high country of Colorado.

Typical afternoon thunderstorms will remain the name of the game on Friday. If you're a mountain biker, be thankful for all of this precip in the Intermountain West but do your best to avoid muddy trails. If you're trying to bag high peaks, wake up early this week and try to be below treeline by 12-noon. 

Outlook for Sat, July 3 – Mon, July 5

The upcoming holiday weekend will continue to feature above-average temperatures for the Pacific Northwest and the northern Rockies, while below-average temperatures remain in place for much of Colorado, New Mexico, and even into Arizona.

Afternoon thunderstorms will fire up each day, mainly focusing on areas along the Continental Divide in Colorado and New Mexico on Saturday, June 3, followed by an increase in thunderstorm activity for areas in Montana and Wyoming on Sunday, July 4, and into Monday, July 5.

Overall, plan for active weather during the upcoming holiday weekend if you live/play in the Intermountain West. My favorite resource to track daily thunderstorm activity is the high-resolution current and forecast radar in the OpenSummit app so download today if you haven't already.

Thanks for reading! Next update on Wednesday (6/30).
