June was the first month since January to be drier than normal. Its 0.73 inches was less than half of the expected 1.73 inches. That said, at 27.31 inches the first 6 months of the year remain among the wettest first halves ever, and if we were to get normal precipitation from here on out, we’d be looking at a top ten calendar year.

With the exception of the North Cascades and perhaps a few spots elsewhere along the Cascade Crest, Western Washington fell in the 20% to 80% normal range, with the Skokomish and Yakima basins being driest.

The greatest 24-hour rainfall total of the month occurred on the 13th when 0.32 inches fell. There were 2 days above 0.10″ and 9 above 0.01″. “Heavy rain” was not reported, “rain” was reported once, and “light rain” 12 times.
