TEMPERATURES January 2020 began with mild temperatures as the first 2 days reached just over 50° then to 60.4° on the 3rd, quickly cooling by the 4th. By the 8th of the month temperatures had returned to near-normal values, even dropping to freezing on the 14th & 15th, the coldest two readings of the month. After reaching 32.8° on the 17th, only 2 more Minimum Temperatures fell below 40° the remainder of the month. The middle of the month also…
TEMPERATURES December 2019 averaged about 2° above the Normal. The warmest weather came 2/3 of the way through the month when Maximum Temperatures reached over 50° from the 19th-21st, including a very warm Minimum Temperature for this time of year of only 50.7° on the 20th, the only Minimum Temperature that didn’t fall below 45° this month. Only one day managed to reach the freezing mark this month as Christmas Eve recorded the coldest Max. and Min. Temperatures with 38.7°…
TEMPERATURES November Mean Temperatures were almost exactly Normal, with Maximums running a bit above normal and Minimums a little below Normal. The first 2/3 of the month had fairly steady Maximum and Minimum Temperatures in the 50s/40s, declining through the remainder of the month. The month’s Average Max/Min/Mean Temps were thus: 1st-20th – 55.6°/44.6°/50.1°; 21st-30th – 45.9°/35.5°/40.7°. As happened in October 2019, the coldest Minimum Temperature waited to occur on the final day of this month, reaching 29.8°, one of…
It was a much drier than normal October in 2019 as the statewide average in Oregon was just 1.60″, only 65% of the 1895-2019 Normal of 2.46″. However, the persistent chilly weather, especially in the northern half of the state, was the more important story this month. Overall, it was the 4th coldest October in the last 125 years with a Mean Temperature of 43.2°, just 1.0° short of the coldest of all time which occurred exactly 100 years prior…
TEMPERATURES This October never saw any really warm weather and overall temperatures averaged about 3.5° below Normal for the month. The highest Maximum Temperature for the entire month was only 66.1° (6th) while 20 days remained ≤60°, with the month’s coolest Maximum being only 42.2° on the 29th, more typical of mid-winter. Mainly due to the first half of the month being mostly sunny and fairly dry, Maximum Temperatures averaged 5.5° warmer than the second half but the Minimum Temperatures…
TEMPERATURES Mean Temperatures were slightly below normal this month; Average Maxima were actually noticeably cooler than average (about 4°) but were balanced by milder-than-normal Minima. It was a typical September in that the warmest weather occurred at the beginning and mostly gradually cooled as the month progressed. The month would likely have averaged above normal had it not been for very chilly air invading the last few days. In fact, the Portland Airport (PDX) only made it to 52° on…
An unusual early-Autumn weather pattern that brought incredible late-September snows to the northwestern U.S. (over 40″ in parts of Montana and 14″ at Oregon’s Timberline Ski Area on Mt. Hood) also pushed very chilly air and valley rain all the way to the Pacific Coast. Under continuous cloud-cover, Maximum temperatures struggled to even make it to 50° in the Portland-Vancouver Metro Area, resulting in the coldest readings ever seen in, at least, 147 years. The Portland Airport (official records back…
TEMPERATURES August Maximum Temperatures averaged close to normal but they were off-set by Minimum Temperatures that averaged about 2° above normal. There were no extended periods of hot or cool weather. Three days reached ≥90°, one near the beginning of the month, the other two near the end of the month, culminating in a monthly Maximum extreme of 95.2° on the 28th, the second-warmest reading of the year, exceeded only by the 96.4° on June 12th. These 3 days of…
With a minimum temperature of 59° this morning at the Portland Airport (PDX), Portland’s third-longest streak with minimum temperatures of ≥60° came to an end at 17 consecutive days. This came close to the all-time record of 19 days ending on 8/1/1998, also recorded at PDX. Here are the Top-5 longest streaks for Portland stations located downtown and at the airport: Portland-Minimum-Temperature-Streak-60°-Tables Please click the above link to access a pdf version of the tables Note – the latest streak…
TEMPERATURES Though July averaged close to Normal, the month began quite cool as Maximum Temperatures for 3 of the first 6 days remained ≤70°; no day was >80° until the 12th, and the first day to reach ≥85° wasn’t until the 20th. Overall, there were just 5 days reaching ≥85°, only one of these attaining ≥90°, this being the monthly Maximum of 90.2° on the 26th. July Maxima ranged 35.2°, from the High Maximum of 90.2° to the Low Maximum…
