DISCUSSION (Today through Friday)... Key Points:

* Only minor impacts expected the next several days - Limited frost/freeze potential tonight/Sunday morning - Breezy winds on Tuesday coupled with low RH for eastside

Further Details:

We will see a weak trough pass through the PacNW today and will bring a front through the region. This front will likely bring very little rainfall for westside areas and is already showing signs of diminishing this morning. The bigger story is behind the front as colder air settles over the forecast area tonight, especially in the agricultural sense given the growing season is underway. At this time, eastside areas have the best shot of seeing temperatures below freezing which is not uncommon for this time of year. For example, normal lows for Klamath Falls this time of year is in the upper 20s. Northern Klamath and Lake counties may be in the upper teens to lower 20s for overnight lows. Westside areas where sensitive vegetation may be an issue will need to be monitored as temperatures could be down around 32-34 overnight Saturday into Sunday morning. Lower elevations on the westside have around a 10-50 percent probability for temperatures below freezing (similar to yesterday's forecast), but the areal coverage for these temps below freezing has shrunk. Meaning less areas have this probability now, especially lower elevations. Normal lows for Medford this time of year is around 38. The potential for freezing temperatures would only be a couple hours around sunrise.

The pattern aloft turns mostly zonal into early parts of next week. A slightly stronger trough than the one today enters the region Tuesday into Wednesday. Rainfall from this system will likely produce higher amounts albeit still on the lower end overall relatively speaking for this time of year. Tuesday in particular will see breezy wind speeds for eastside areas. This will be combined with low RH values in the 20 percent range with precipitation likely not amounting to much on the eastside. That said, it should be noted minimum RH values have come up slightly for Tuesday with less areal coverage of 20 percent. Given the lack precipitation we could see at least an elevated fire weather conditions Tuesday for eastside areas. To some extent, we could see these elevated conditions continue through Wednesday but at this time wind speeds may not be as high as Tuesday. Overall, the next several days will be noted by dry conditions and low RH values, especially eastside areas.

Marine
Updated 300am PDT Saturday, March 21, 2026...Small craft conditions begin this morning for all areas. A thermal trough strengthens today, bringing gusty north winds and steep to very steep seas to the waters from Cape Blanco south. Brief gales are possible for areas from Gold Beach south in the late afternoons and early evenings today and tomorrow. A Hazardous Seas Warning has been issued for later today and goes through early Monday for areas south of Cape Blanco, with small craft advisory conditions north of Cape Blanco.

The outlook is for conditions to briefly improve Monday afternoon and evening. Advisory strength winds are likely on Tuesday as a cold front swings through the waters. Gales are also possible if the front is strong enough, especially for areas from Cape Blanco northward on Tuesday.
