Here is my weekly weather quiz question for the last time What is the “PDSI?” Here is the correct answer. PDSI is the Palmer Drought Severity Index – an index used to gage the severity of drought conditions by using a water balance equation to track water supply and demand. This index is calculated weekly by the National Weather Service.

An Atmospheric River has been pumping a lot of moisture into California, but luckily not as much into Oregon The graphics for days 1-3 show the complex frontal system moving through Oregon Monday. The graphics for days 3-7 Wednesday through Sunday show complex frontal systems approaching the Pacific Northwest the pushing through Wednesday, Friday, and next Sunday..
Note: A check on the many groundhog predictions Friday shows they all predict an early Spring, But Spencer Butte Bob, My personal Groundhog, did see his shadow Friday morning (sunshine and clouds) in Eugene predicting six more weeks of winter. If our current weather indicates what the rest of Winter will be like then I’ll take it.
