From Downpours to Heatwave: Weather Update for Portland and Oregon

Portland experienced heavy rain and lightning strikes due to an unstable atmosphere caused by an upper-level low, but will see dry weather for the next 7-10 days. A rare May heatwave is expected for the next 1-2 weeks, with record-setting temperatures likely for Mother's Day weekend. The upper-level high position will cause easterly wind down off the Cascades and the Coast Range, increasing the risk of fire. The hottest Mother's Day on record was in 1973, and this year's forecast of 94 degrees could break that record.
