Spring has had a difficult time showing its pretty face here in the Portland area through mid-April, not so much due to very cold air but of a lack of any warm air. Well, that ended abruptly this week. The Portland Airport (PDX) had not seen a maximum temperature of 70°F. or higher since October 28, 2017. With much anticipation, forecasts were finally calling for high temperatures reaching into the 70s, which did finally occur on April 23rd when it…
TEMPERATURES For the second consecutive late-winter month, the second half was cooler than the first half, the opposite of what is Normal. Only 2 days this month managed to reach ≥65°, with 65.0° on the 11th and a monthly Maximum of 70.3° on the 12th, the latter being the warmest temperature since 83.9° on Sept. 28, 2017, nearly 6 months ago, hinting at Spring finally kicking into gear. However, the coolest Maximum Temperatures didn’t occur until the 22nd-24th with readings…
TEMPERATURES Following one of the area’s warmest Januarys, February continued the mild winter weather through much of the first half. Old Man Winter finally decided to show his face for the second half, not only with temperatures but also with snowfall. Only 1 Minimum Temperature ≤32° was recorded in the first half, reaching 29.4° (13th). Subsequently, 6 consecutive days reached ≤32° from the 18th-23rd, with the month’s Minimum Temperature falling to 22.0° on the 23rd. Splitting the month in half,…
TEMPERATURES January was quite mild, in fact, one of the warmest on record. We had no Minimum Temperatures that even reached freezing this month as the low was only 35.5°. Though 16 days did manage to fall to ≤40°, Mins stayed above 40° from the 9th-17th. On the Maximum side, one day did manage to just reach 60° and 16 total days were ≥50°. When looking at the first and second halves of the month, temperatures averaged almost exactly the same…
With the end of January now upon us, it has certainly been a mild month in the Portland area. In fact, the Portland Airport (PDX) recorded its second-warmest January Mean Temperature since records began there in 1939, nearly 80 years ago! Only 4 days in the month averaged below the 30-year Normal, the greatest of these having just a -3.0° departure. When combining the longer-term record of the official downtown station locations with a Period of Record (POR) back to…
i just stepped outside and happened to look up and see this iridescence from a contrail. .
TEMPERATURES Average Temperatures were fairly steady throughout the month with a difference between the Maximum and Minimum of only 8.2°. The Average Max/Min/Mean Temperatures December 1st-15th vs. 16th-31st: 44.7°/36.6°/40.6° vs. 43.6°/35.2°/39.4°. There was no unusual warmth or cold – the month only featured 5 days reaching Maxima ≥50° and most of those just barely, while Minima reached ≤32° on 9 days, including 7 in a row from 20th-26th. The greatest diurnal temperature range was just 12.9° (12th, 19th, 27th), the…
TEMPERATURES A steady monthly temperature pattern occurred. The Average Maximum/Minimum/Mean Temperatures for November 1st-15th vs. 16th-30th were almost exactly the same: 52.0°/42.4°/47.2° vs. 51.9°/42.4°/47.2°. The month’s warmest weather waited until Thanksgiving time when the Minimum Temperature only dropped to 54.9° on the 22nd, several degrees above the Normal Maximum Temperature for the date. This warmth was balanced just a few days prior when the Min. Temp. dropped to 33.8° on the 19th (the low for the month), the coolest temperature…

Splitting the month in two, the Average Max/Min/Mean Temperatures for Oct. 1st-15th vs. 16th-31st were thus: 61.7°/44.7°/53.2° vs. 61.9°/48.1°/55.0°. This was mainly due to a persistent end-of-month easterly wind that funneled in mild air through the Columbia River…
TEMPERATURES: The normal steady monthly decline in temperatures occurred through this September. The Average Maximum/Minimum/Mean Temperatures for Sept 1st-15th vs. 16th-30th were thus: 82.9°/59.1°/71.0° vs. 68.1°/51.8°/60.0°. There were 5 days with Max. Temps. ≥90°, all occurring over the first 11 days of the month. A brief warm-up occurred at month’s end with 2 days reaching ≥80°, otherwise Maximum readings mostly stayed in the 50’s and 60’s over the latter half of the month. As far as Minimum Temperatures, there were…
