Cold Start In Roseburg Gives Way To Weekend Warmup, Then Rain Returns Early Next Week

ROSEBURG, Ore. — Frosty conditions started the day Friday across Roseburg and parts of Douglas County, but a warming trend is expected through the weekend before wetter weather moves back into the area early next week.

The National Weather Service said a Frost Advisory remained in effect until 9 a.m. Friday for the valleys of Coos and Douglas counties. In Roseburg, Friday’s forecast called for areas of frost before 8 a.m., followed by mostly sunny skies and a high near 64.

Temperatures are then expected to climb through the weekend. Roseburg’s forecast shows a low around 40 Friday night, followed by a high near 74 on Saturday. Clouds will begin increasing Saturday night, with a 20% chance of rain after 11 p.m. and a low around 49.

Sunday is expected to stay mostly mild, with a 20% chance of rain and a high near 70. Rain chances increase Sunday night, when Roseburg has a 40% chance of rain and a low around 49.

A wetter pattern is expected to settle in by Monday. Roseburg’s forecast calls for rain likely Monday with a high near 68 and a 60% chance of precipitation. Rain remains likely Monday night, with a low around 46.

The unsettled weather is expected to continue into the middle of next week. Rain is likely Tuesday, mainly after 11 a.m., with a high near 64, followed by more likely rain Tuesday night and a low around 47. Wednesday also brings a strong chance of rain, with a high near 59, before conditions begin to ease later in the week.

By Thursday, Roseburg’s forecast shows just a slight chance of rain with partly sunny skies and a high near 62.

Forecasters said the broader weather pattern across southwest Oregon will shift as a slow-moving low pressure system approaches. While Friday morning brought freezing temperatures and frost to many inland valleys, high pressure is expected to bring a brief warmup before the system increases chances for showers and possible thunderstorms early next week.

The National Weather Service said isolated thunderstorms could develop as early as Monday afternoon, with thunderstorm chances continuing Tuesday. It is still too early to say exactly which areas will be most favored.

Winds are also expected to increase in parts of the region, especially in the Shasta Valley and east of the Cascades, where gusty southerly winds are forecast Sunday through Wednesday.
