Area Forecast Discussion National Weather Service Medford OR 1253 PM PDT Wed Apr 15 2026
DISCUSSION
The front is passing through the area this afternoon, with rain, gusty winds, and mountain snow. Steady rain will taper off as the front passes to the south and east later today, with showers continuing overnight, and potentially some isolated showers persisting into Thursday morning along the coast and the northern Cascades.
The cold air mass behind the front looks to bring cool overnight lows from tonight into Thursday morning and again from Thursday night into Friday morning. A Frost Advisory will be in place for the Rogue, Applegate, and Illinois valleys for tonight into Thursday, as lingering cloud cover looks to keep temperatures just above freezing concerns. Localized freezing conditions may be possible in some areas, notably in the southern Illinois Valley. A Freeze Watch covers the Thursday night-Friday morning timeframe, as there's some question how cold that night will get.
A number of hazard products are in place to further communicate the impacts of this active period. A Winter Weather Advisory for the Cascades from Crater Lake northward and above 4000 feet remains in place through Thursday morning. A Wind Advisory for most of Lake County as well as the Warner Mountains and areas north of Alturas in Modoc County highlights dangerous travel conditions in these areas.
An upper ridge will bring drier conditions and warmer daytime highs on Friday and Saturday. Long-term guidance shows a low pressure system approaching from the northwest. Details for this system remain coarse, with some variations between the ECMWF and GFS outcomes. This system may bring a southerly flow pattern that tends to focus precipitation at Curry County as well as parts of western Siskiyou County, per ECMWF imagery. Or it might bounce off a ridge and linger over the Pacific before moving inland on Monday, per GFS imagery. Initial snow levels are in the 5000-7000 foot range, which would limit winter impacts. Showers may continue beyond Monday, depending on how this system behaves.

.AVIATION (18Z TAFs)...
A front continues to pass through the region bringing rainfall, breezy winds, and ceilings just above MVFR. This will likely continue through early this afternoon, but we are expecting showers to become more isolated this afternoon with skies clearing behind the front. The big questions is how much clearing will occur tonight. At this time, we have omitted any visibility restrictions and low clouds overnight, and this may need further evaluation for subsequent TAFs. That said, at this time KRBG has the relatively highest probability for visibility restrictions at about 25% overnight.

Updated 1200 PM PDT Wednesday, April 15, 2026...A passing front will continue to bring breezy winds and steep seas across all waters through tomorrow afternoon. Isolated showers are possible tonight through tomorrow morning, and there could be an embedded thunderstorm tonight (20%-25%) around and north/northwest of Cape Blanco. Localized areas of very steep and hazardous seas are possible north of Cape Blanco tonight. Conditions improve late Thursday afternoon; however, a weak thermal trough may bring gusty northerly winds to the waters south of Cape Blanco late Thursday into Friday. Another active system may bring additional rainfall and steep seas this weekend.
