Holiday Heat!!!

What to Expect

- Nice Fourth!!

- Very Warm

- Very Dry

It will be a great day to celebrate Independence Day! Saturday is looking very similar to Friday with very warm temperatures!


Sunday Changes
We get a bonus day Sunday with more sunshine and warm temperatures. Later in the day you may notice some clouds streaming in from the south as a disturbance sneaks under the area of high pressure that has kept us warm and dry the past few days. As moisture moves up from the south, the threat for mountain thunderstorms will increase. We will have the threat for showers across all of western Washington as early as overnight Sunday into Monday.

Big Changes Monday
A broad area of lower pressure will move over the region and bring us much stronger onshore flow at the lower levels of the atmosphere. This onshore flow will mean the end to the very warm weather as cool air from the pacific invades western Washington.


Extended
The threat for shower will be with us for at least the first half of next week. Later in the week we will return to our more normal morning clouds and afternoon sun. Highs will remain cool in the upper 60s to mid 70s.

Have a safe night and a great Sunday!

Northwest forecast from NWCN

Saturday

Hot as a Firecracker
Ho hum: another sunny day in the Northwest. Once again, the Fourth of July will be hot and dry across the region.

With high pressure still in command, look for sunshine and highs in most places in the 90s, with a few lower 100s in the Columbia Basin. A heat advisory is in effect for the lower Basin through the weekend, while the Willamette Valley remains under a heat advisory for Saturday. In addition, fire danger is rising too. A red flag warning for dangerous fire condtions is in effect for western Washington.

Changes are coming by next week. An upper-level low will replace the high, bringing cooler temperatures and a chance of showers. Monday into Tuesday, we'll see highs 10-20 degrees cooler, and a welcome chance of showers, especially in the mountains.

Have a good weekend and be safe out there.
