DISCUSSION

The last front brought some light rain to the coast and coastal range. Accumulation totals maxed out at 0.02 inches near Coquille. It will be another night of high clouds moving over the forecast area with the potential for some patchy fog. Dewpoint depression is around 1-2 degrees in Medford, Grants Pass and Roseburg and the visibility has lowered slightly here. However, the high clouds should inhibit fog formation. Plus the dry ground won't help here as it hasn't rained much over the last few weeks with drier air mixing to the surface daily.

An occluded front will eventually push into the forecast area on Sunday with a little more rain falling over the region. The coast will see the most rain with up to 0.25 inches around Brookings and North Bend. However, conditions will dry out significantly the farther one moves east. Medford might miss out on any rain and the east side will likely stay dry through Sunday into Monday. In any case, this is a low impact front with some wetting rain along the coast.

A ridge will begin to build again to start the work week and continue to strengthen into Tuesday. Stagnant air would be the impactful weather here as we could struggle to mix to 1000 feet above ground level here in the valley. A slightly higher sun angle and no fog could help prevent an air stagnation advisory, but we still have the lower winter sun angles and weak mixing. Plus wood burning could be enhanced with cold overnight lows. We're still forecasting near freezing and sub freezing temperatures through much of next week.

High temperatures will also be usually warm. Data shows EFI values around 0.7 to 0.8 between Wednesday and Friday, which suggests plenty of ensemble members above the climate mean around this time of year. We'll approach some high temperature records on Wednesday and Thursday near Alturas and Klamath Falls. Ensembles are pretty confident it will remain dry through the 7th, then things could start to change after that. We're currently forecasting a 30% chance of rain around 0Z on the 8th.

AVIATION...30/06

VFR ceilings of mid and high level clouds will persist through Friday evening. A very weak front will bring virga and perhaps occasional light showers to Coos and Douglas counties in the afternoon, but very little precipitation is expected at the surface, if any at all.

MARINE...Updated 200 AM PST Saturday, January 31, 2026

High and steep seas will remain in the waters and these conditions will be hazardous to small crafts through the day. Another occluded front will keep seas high and steep and hazardous to smaller crafts during Sunday. Another elevated swell group will move through the waters on Monday with swells around 12 to 13 feet at 15 to 16 seconds. Seas lower briefly on Tuesday before building again on Wednesday.
