Warm Weekend Ahead, Rain By Monday

Thursday was a warm day, quite a comfortable day in my opinion. High temperatures reached the upper 60s to low 70s, a preview of warmer temperatures ahead. Thursday’s highs are below.


Warmer days are ahead...with highs of 75-80 degrees likely this Friday and this weekend. The forecast for Puyallup from Weather Underground is below.


Notice highs of 77+ degrees from Friday to Sunday, with cooling highs on Monday (near 70 degrees). Rain returns on Tuesday, with a chance of thunderstorms on Wednesday. Highs on Tuesday and Wednesday will drop to the 60s, barely cracking 60 degrees on Wednesday.

What isn’t shown on this forecast is diurnal sea breeze winds. In short, these are winds that increase during the day due to pressure differences between land (lower pressure) and water (higher pressure). The pressure differences are caused by the land heating faster than water, and since winds flow toward low pressure (which is created by heat), thus creating the sea breeze effect.

If you’ve noticed winds increasing in the late morning or afternoon on warm, sunny days, that is the sea breeze effect. 

In the days ahead, expect north to northwest winds gusting 20-25 mph. These winds peak in the afternoons.
