In the Seattle area, there were 60s near the water but low 80s over northeast Seattle away from the water. Mid 80s over the eastern suburbs.
What about today? An interesting situation.
The temperatures aloft, say at 5000 ft, are nearly identical to those of yesterday. But the offshore (easterly) flow is weaker. The north-south pressure difference is also weaker, so the cooling northerly flow that moderated Seattle yesterday will decline today. The figure below shows the temperatures and winds above Sea Tac for the past 24h. At 850 hPa (about 5000 ft) the temperature line (red) is almost horizontal. No change. But the strong low-level easterlies are gone.
So in this situation, one might expect that the eastern suburbs of Seattle will cool a bit (say to around 80F), while Seattle and the lower elevations will be similar or cool slightly.
Another summer-like day. Enjoy.
