HAPPY VALLEY, OREGON WEATHER: FEBRUARY 2022

TEMPERATURES

February 2022’s area Average Temperatures were slightly below Normal, with the greater departures being with Average Minimum Temperatures. The month was a topsy-turvy one compared to most Februaries as the first half was quite a bit warmer than the second half. Maximum Temperatures were cool the first two days but then hovered around 50° through the 10th, followed by 3 days ≥60°, peaking at 63.3° on the lucky 13th before retreating to around 50° through the 20th. High Pressure in the northern Pacific that had been keeping cold air from infiltrating our area, retrograded, allowing cold, arctic air to plunge southward and westward through the Columbia River Gorge, suppressing readings into the mid-30s to low 40s from the 21st-25th before recovering back to the 50s to end the month. 

Except for a single day below freezing on the 6th, Minimum Temperatures mostly hovered around 40° through the 20th, then dropped to near freezing or below from the 21st-26th, bottoming out with 23.0° on the 23rd.

Splitting the month in two, the Max/Min/Mean Temperatures were thus: 

– 1st-14th 51.4°/38.3°/44.9°

– 15th-28th 46.6°/34.9°/40.8°


The greatest diurnal range was 23.7° on the 13th (63.3°/39.6°), the least was 4.6° on the 2nd (43.3°/38.7°)

PRECIPITATION

It was a below Normal month for rain and snow but would have been far-below Normal had it not been for the Atmospheric River that drenched the area at the end of the month. Only half of the month recorded measurable precipitation and just 1.40″ had fallen through the 26th by the 7:00 AM Observation time and there was a nice 6-day stretch with no precipitation from the 8th-13th. As the persistent rain began midday on the 27th, there was no stopping it through the end of the month and beyond, with 0.94″ accumulating by the 7:00 AM observation on the 28th. This gave a monthly total of 2.34″ at that time, with another inch-and-a-quarter falling by midnight to end the month. Snowfall was light but accumulated on 2 days, 0.1″ on the 21st and 0.5″ on the 24th, bringing the seasonal total to 9.6″.
