Trader consensus on Seattle's April precipitation at the Sea-Tac Airport (CLISEA station) reflects a dry start, with just 0.69 inches recorded through April 10—below the climatological normal of about 1.1 inches for the first third of the month—tempered by uncertain forecasts for the remaining three weeks. NOAA's spring outlook from late March signals a 40-50% chance of below-normal totals across western Washington, influenced by persistent upper-level ridging and neutral ENSO conditions limiting Pacific storm tracks. Model ensembles like the GFS and ECMWF show subdued frontal activity ahead, aligning with April's historical decline in wet days from 45% to 33%, yet late-month surges remain possible, keeping 3-3.5 inches (31.5%) narrowly ahead of 2.5-3 inches (29.5%). Watch NWS updates and new CPC guidance for shifts.

The resolution source for this market will be NOAA, specifically the figure for April 2026 when the "Monthly summarized data" for "Seattle City Area" is selected with the variable set to "Precipitation" at the https://www.weather.gov/wrh/climate?wfo=sew link once that figure is finalized for the whole month of April 2026.
If the reported data falls exactly between two brackets, this market will resolve to the higher bracket.
The resolution source for this market measures precipitation to 2 decimal places (e.g., 1.54), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
