June is Gone and Summer has Arrived!

The first official day of summer has come and gone and so has the month of June. Here in the Northwest June is tends to be a spring month, not a summer month. June did bring with it some very summery weather including the hottest day I have recorded since the all time record high was set back in July of 2009. That was also the first triple digit heat I have recorded in nearly two years, the last time was, July 30th, 2015.

After a cooler than average trend that began in December last year and continued through last month, June emerged a tad warmer than average and a touch on the dry side as well.

June produced two days in excess of 90° at my location including that scorcher on the 25th when the mercury when stratospheric at 103.6°. That toasty warm daytime high was helped by a relatively warm overnight low of 63.1°. That was the warmest overnight low of the year. Despite the blistering heat mark set last month June was not without its chilly moments. True to form, the late spring weather did produce four nights in the 40s including the chilliest night on the 5th when the bottom came at 43°. The coldest daytime high arrived on the 12th when I failed to reach 60° for the first of two sub 60s in a row. The 12th was 58.1° followed by a crisp 59.4° on the 13th. June gave us 17 days above 70°, seven of which busted out over 80°, two days above 90°, and the aforementioned single day above 100°.

Rainfall came in light of my 16 year "normal" but well within typical June fluctuations. The bucket caught 1.46 inches of rain. June had some scattered thunderstorm activity that probably pushed nearby stations well above 2 inches, but my station seemed to avoid those downpours this time 'round. The soggiest day came on the 15th when I saw 0.51 inches and that was one of just two days where I recorded more than 1/4 inch.

The ever so fickle, Miss Spring was in control of June with bouts of both chilly and hot weather. We enjoyed a delicious 16 days of sunshine against just 8 days of rain, most of which was drizzly in nature. Heading into July it looks like we will have rather typical summer weather for the next several days. The NWS in Portland has this forecast this morning.



The metro Portland-Vancouver region enjoys some of the best summer weather on this planet. Temps don't like to get above ninety much and triple digits are worthy of front page headlines. We simply bask in mildly warm, mostly sunny days for the next 75 days or so.

Summer has arrived so soak it up my friends, soak it up.

Summer Season is here, but Summer is not.

The merry month of May is in the books and statistically is was pretty darn 'normal'. Overnight lows averaged almost dead 'normal' and the average daily high was about a degree above 'normal'. Rainfall came in well under normal but May is a month with a wide range of variance so it was really pretty typical. The Memorial Day Weekend was pretty nice with mid eighties on Saturday and Sunday and a mild 76° on Monday. June is starting off cloudy and damp and that is typical as well. For most of America, June kicks off the summer season. Here on the west side of the Cascade mountains, June remains firmly in the grasp of spring and her volatile moods.

Temperatures were literally a roller coaster ride on the chart. On May 4th we had a nice sunny 83.1° for the high and it was followed by a chilly 59.5° on Cinco de Mayo. So went the whole month.

The only hot day was the 22nd when my thermometer topped at at exactly 90° the only reading to breech the nineties all month. I had eight days with a reading in the eighties or better and ten days that failed to reach 60°. The warmest overnight low came on the 4th with a summerish 56.5° and the coolest temperature came the morning of the 1st when it was a nippy 37.9°. That was one of four mornings that dipped into the thirties overnight. Such is the fickle nature of spring time in the Northwest. The chilliest daytime high was a cool 52° on the 13th.

As for the rainfall it shows up as below average but really May is often beset with light thunderstorms and scattered showers. My rainfall was light but other ares very near me probably recorded above average rainfall. I had nary a day above 1/4 inch of rain and just 8 days with precipitation. That said there were a couple of days where the region had strong thunderstorms including one that triggered an alert from the "Emergency Broadcast Network". That alert was for the northern part of Clark County where serious lightning strikes, flash flooding, and golf ball size hail were coming down. I got light showers during that event. Another amazing light show went on for nearly two hours to my south, but again the rain from that one missed me. So 1.24 inches was my bucket total for May well under my 3.25 average. The wettest day was the 16th with 0.24 inches.

June will likely be a roller coaster for the first half before we see a summer pattern develop. Such it is in late spring. May and June tend to be unpredictable. But the next sic weeks will deliver long, long, long daylight as we move into that period where we have 18 hours of light, dawn to dusk. Cloudy or not, that is good stuff :)
