Good morning everybody!
We’ve got another bright and beautiful Monday morning to start off our work week! There are a few cirrus clouds over the area indicating some increasing moisture in the upper-levels of the atmosphere making its way into the region, and it appears like there may be a bank of stratocumulus clouds across the sound, indicating that there was a weak marine push that didn’t make it into the I-5 corridor. You can clearly see the low clouds on the visibile satellite image above. Regardless, expect dry conditions with highs on either side of 80 degrees today here in Western Washington, warmer as you go south towards the Willamette Valley and cooler along the coast, where we will be cooler and cloudier than yesterday.
These high clouds are ahead of a very weak low pressure system that will impact our area tonight. It is too weak to give us any rain, but it will help usher in a marine push overnight tonight into Tuesday that will cool our high temperatures on Tuesday back to the mid 60s to the coast and low 70s for the interior.
We begin a warming trend once again on Wednesday as a large ridge of high pressure moves into the area. As I’ve been advertising for a while, we will warm to our highest temperatures of the month on Thursday and Friday as this ridge settles overhead, with max highs near 90 in Western Washington and in the mid-upper 70s on the coast.
Our brief heat wave ends Friday night, and Saturday and Sunday look average for this time of the year, with morning clouds, afternoon sunshine, and highs in the 70s.
Have a great week!
