Current early June rainfall accumulation in Seattle has already reached roughly 1.2 inches—near or above the 1991-2020 monthly normal of about 1.45 inches—yet long-range outlooks favor drier conditions for the remainder of the month as ENSO-neutral conditions give way to emerging El Niño, which typically suppresses Pacific Northwest summer precipitation. NOAA and Washington State Climate Office guidance highlight elevated odds of above-normal temperatures and below-normal rainfall through June-August, consistent with historical analogs where El Niño strengthens the subtropical high and shifts the storm track northward. Short-term model consensus points to mostly dry, stable high-pressure patterns after mid-month, though scattered showers remain possible and could add variability within the 1-2.5 inch range that currently dominates trader-implied probabilities. Resolution hinges on final NWS totals measured at Sea-Tac, with limited time left amplifying sensitivity to any late-month systems.
