After an afternoon with many temperatures in the 80s to near 90 across the area, there will be some subtle changes on Wednesday.
However, the changes aren’t likely to be enough to keep the central Sound — particularly the Seattle metro area — from another pretty hot day.
For that, Wednesday is another Pinpoint Alert Day as KIRO 7 meteorologists say the heat stress for those attending the World Cup match on Wednesday will be in the moderate to high category, so hydration is a must!
Following morning lows in the 60s, I’m forecasting a high in the mid to upper 80s in Seattle Wednesday. The tricky part of the forecast is how much high cloudiness could move in through the day, shielding us from the sun somewhat. If cloud cover is thicker than forecast, temperatures won’t quite get as warm.
Elsewhere, the onshore flow off the Pacific will slowly pick up but highs will still be in the 70s to low 80s for the North Sound, the South Sound and south of Puget Sound.
A major weather change comes in with a transition day Thursday with more clouds and highs only barely getting into the 70s. Natural “air conditioning” with the flow of wind off the Pacific will be in full swing.
Then, as a trough of low pressure approaches the area, the clouds will bear rain as early as Thursday evening nearer the coast and through Friday areawide. Rainfall could be heavy in parts of the north Sound, north interior and coast, while lighter rain showers are likely across the central Sound. Still, for the second local World Cup match this week, it will be markedly different, with cool breezes and high temperatures only in the low to mid 60s. There is also a slight chance for a late- day thunderstorm.
Overall, this rainfall will be very beneficial for the region, if disruptive.
Showers will taper through Saturday but still some showers of rain will be around with highs in the 60s. A drier weather forecast is in store from Sunday into next week, but temperatures likely stay below average — in the 60s around Seattle.
