Heat Wave Expected to Bring Near-Triple-Digit Temperatures to Roseburg This Weekend
A heat wave is expected to build across southern Oregon this weekend, bringing sunny, dry conditions and highs near 97 in Roseburg by Sunday. Forecasters say temperatures may remain well above normal into early next week.
ROSEBURG, Ore. — A stretch of warmer and drier weather is expected to build across southern Oregon through the rest of the week, with Roseburg likely to see its hottest temperatures of the year so far by Sunday.
The National Weather Service forecast calls for sunny skies and a high near 84 on Thursday, followed by another high near 84 on Friday. Winds will increase Friday afternoon, with north winds around 8 to 13 mph and gusts up to 20 mph possible.
The bigger change arrives over the weekend.
Saturday is expected to be sunny with a high near 92 in Roseburg. By Sunday, temperatures are forecast to climb to around 97 degrees, with clear skies continuing Sunday night and lows only falling to around 65.
Forecasters say a strong ridge of high pressure will build over the western United States, allowing temperatures to rise several degrees each day into the weekend. The heat is expected to peak Sunday through Tuesday, with many areas running 20 to 25 degrees above normal for early to mid-June.
Some inland areas west of the Cascades could reach the upper 90s or triple digits early next week. Medford and Grants Pass could approach 105 degrees, while parts of western Siskiyou County may climb even higher.
Along with the heat, humidity levels are expected to drop each afternoon. Fire weather officials said the warming and drying trend will bring low minimum humidities during the peak of the heat wave, though widespread critical fire weather conditions are not currently expected. Gusty afternoon breezes could still create localized concerns, especially Friday.
The marine forecast also points to rougher conditions along the southern Oregon coast, where a strengthening thermal trough is expected to bring gusty north winds and steep to very steep seas through the weekend. The worst marine conditions are expected south of Cape Blanco.
Forecasters said the ridge may begin to weaken by the middle of next week, but temperatures are still expected to remain above normal. There is also a slight chance that the breakdown of the heat wave could bring some thunderstorm potential around Wednesday or Thursday, mainly over far northern California and areas east of the Cascades. Confidence in that part of the forecast remains low.
For Roseburg, the next several days are expected to stay dry, sunny and increasingly hot. Residents should plan for rising afternoon temperatures, especially for outdoor work, recreation and pets.
