From supermoons to super warmth to eclipsed suns to missing suns, it's been quite the month for variances around here.
I thought I'd try a new tradition in the blog with a monthly recap of the best weather photos and events (See photo gallery link on the left), plus give the stats for the just-finishing month and where we're heading from here.
May began quite wet with 0.84" of rain falling across the first four days -- May 3 set a daily rain record with 0.75" -- with temperatures stuck in the 50s. But lo and behold the weather took a turn for the sunnier, as Seattle rattled off a 16-day streak of no measurable precipitation, highlighted by the first 80 degree day of the year on May 14.
Then another wet streak with just over an inch of rain over three days from May 20-23 -- another daily rain record on May 21 of 0.55" -- and then some spits of drizzle that brought five of the next eight days with a Trace or 0.01" of rain -- the true way that Seattle gets its rainy reputation, as that five days of rain and drizzle amounted to a total of 0.02" in the rain gauge.
Despite the mid-month warmth, the month will end up a touch below normal for temperatures and a touch above normal for rainfall.
But there were plenty of other big events this May.
We kicked off on the weekend of May 6 with the big Supermoon sighting, where the cloud just parted enough to see the show.
On May 18, what was supposed to be a dry day was anything but for some, as a freak Puget Sound Convergence Zone brought nearly 1/2 inch of rain to South Seattle, but nary a drop a few miles to the north and south. Had that storm hit Sea-Tac Airport (it didn't -- just a trace there) May's rainfall for the month would have been considered well above normal.
We turned our attention back to the heavens on May 21 as a rare annular eclipse graced the west coast, although clouds ruined the show over the Pacific Northwest.
Finally the clouds themselves were the show, as a round of strong thunderstorms moved through the Seattle area. (And Portland too!.)
The month ended on a rainy but fairly tranquil note.
June typically features a lot of days with morning clouds and then afternoon sunshine -- many times it's sort of the "false start" of summer that will get the moniker "Juneuary". The 30 day forecast for June is leaning toward a cooler but drier than normal month. Forecast models for the first 10 days would agree with the cooler part but actually maintain our showery pattern for a while.

General Spring in Review
Just to finish the month up, here is nice time lapse video of the spring around here in general:
