Office of the State Climatologist of Oregon @laoneill25 - housed at Oregon State University @OSUCEOAS! Oregon climate, weather, and impacts.

Joined July 2010
The latest reservoir storage numbers are in for Oregon, and ... we're doing pretty well overall, especially compared with the last 4 years! The outlier is Cougar Reservoir, which has substantially altered operations in 2022 to increase flows on the mainstem Willamette.

Western Oregon was hit by a "flash drought" over the past 2-3 weeks, according to OR State Climatologist @laoneill25. Warm temps and east winds “sucked record amounts of moisture from the soil." Impact to farming, drinking water, wildfire, etc. Story: https://t.co/vHd9UsXR6A

🔵 Since January 1, much of Arizona and New Mexico have observed normal to well-above-normal precipitation levels. Dry conditions expanded in western Oregon and Washington in response to short-term dryness and very low streamflows. https://t.co/YL48ikIX2d

Although signals point to drought development, the good news is that most of Oregon's reservoirs are doing fairly well this spring. Good reservoir storage cannot mitigate all drought impacts, but it can provide valuable water supply during a dry summer.
Streamflows and soil moisture in western Oregon and Washington have dropped rapidly over the last 3 weeks due to poor precipitation and excess evaporation. The drought monitor tomorrow will start depicting these concerning trends. #orwx #wawx

Way back in April 11, 1904, Oregon had one of its warmest April days on record, with 80s and 90s in western Oregon. The map shows the daily highs available then. These types of hot days typically occur during offshore wind events with a strong high pressure ridge to the north.

Why and how do non-native invasive plants contribute to wildfire risk? OCCRI director @efleishman discusses with Time magazine. https://t.co/f4cTf9wgBi

Fast-growing and quick to burn, multiple species of non-native, invasive grasses contributed to the devastation in Maui.

In conclusion, it will be a historic heatwave for Eugene, and for other parts of western Oregon based on the historical climate records we have.

The forecast low temp Monday night is 67°F, which would be the 2nd warmest night on record. 5/

Since 1938, the Eugene airport has recorded only 96 days with a high temp of 100+°F out of about 31,000 days. If the forecast holds, 4% of the warmest days in Eugene's recorded history may occur this week. 4/

As forecast, the 4 days with 100°+ will tie the longest streak in recorded history at the airport (going back to June 1938) with 2015 and 1981. A 106°F temp on Monday would tie its 3rd highest recorded temp, with only 1981 and 2021 having warmer temps (of 108° and 111°). 3/

Western Oregon is headed for a heat wave over the next week that is forecast to be intense and long. Will it be historic? Short answer, yes, but not like June 2021. 1/

April was a much wetter and cooler month after record to near-record dry and warm conditions from early January into early April. Learn more in Oregon's May Water Supply Outlook Report: https://t.co/WOVXWfr7Y1

Reservoirs in NW Oregon boosted by a wet April and good snowpack, but those elsewhere are doing poorly. In those areas, storage levels are critically low and well below storage levels at this time last year. #ordrought #drought #orwx

Great to see @CoCoRaHS highlighted in one of the nation's top newspapers.

Called the Community Collaborative Rain, Hail & Snow Network, the nonprofit network has volunteers that measure and map rain, hail and snow in all 50 states.

❄️☔️📹A lot of folks are curious about how much precipitation and snowpack we've received, how this affects the current drought, and whether this pattern will continue. We address these questions in our latest video update. #orwx #cawx

“I think the real story here is that we used to get snow more often in April in Portland and now we don’t.”
opb.org
Climate scientists say Monday's snowstorm in the Portland metro could be related to climate change in the region, but global trends show it could be unrelated.

The # of sub-freezing days is indeed becoming less frequent during spring (March-April-May) compared with earlier in the 20th century. Subfreezing days in April are now infrequent compared with historical conditions.

The trend in Portland, OR is for fewer days with min temperatures at or below freezing. This shows a time series of the # of sub-freezing days/year at the Portland Airport since 1940. Avg was about 40-45 sub-freezing days/yr in the 1940's, and now ~30 days/yr, a reduction of >20%
