**Forecast models from NOAA and private sources converge on an overnight low in the upper 50s to low 60s for Seattle on August 22, driven by increasing cloud cover, light southerly flow, and marine air moderating radiational cooling.** Recent observations show highs near 80°F on August 20-21 giving way to overcast skies and a slight shower chance, which elevates dew points and limits temperature drops below historical averages around 56°F. The 58-63°F range captures the bulk of trader positioning because ensemble guidance shows minimal spread, with any clearing potentially allowing a dip toward 56-57°F while persistent clouds favor the warmer side. Official resolution relies on the Sea-Tac minimum, typically recorded near dawn under these synoptic conditions.
