Area Forecast Discussion

National Weather Service Medford OR

244 PM PDT Sun Jun 28 2026



.DISCUSSION...Cool temperatures and cloudy skies continue today as 

an upper trough lingers over the area. Northerly flow aloft is 

keeping slight shower chances (20-40%) over the Cascades north of 

Crater Lake, but activity elsewhere should be minimal.



Overnight lows look to be on the cooler side again as well. 

Observations from areas east of the Cascades indicate a patchwork of 

brief frost/freeze conditions from Saturday night into this morning.

Current observations show either warmer temperatures, higher 

humidities, or a combination of both. The conclusion, at least for 

this discussion, is low confidence in hazardous conditions and no 

need for a Frost Advisory. However, areas where cloud cover 

decreases this afternoon would see more radiational cooling. 

Individuals with sensitive plants or animals may want to consider 

preventative actions.



The upper trough remains in place but weakens through the week, 

bringing a gradual warming trend but with temperatures staying below 

seasonal norms through Thursday. Shortwaves following the trough 

look to keep afternoon breezes just above normal speeds, especially 

over elevated terrain. Winds of 10 to 20 mph with gusts approaching 

30 mph may be present at higher elevations. Drier air aloft is 

minimizing thunderstorm chances through the forecast period.



Currently, Friday is showing a return to normal temperatures. A weak 

upper ridge looks to nudge daytime highs about 5 degrees above 

normal across the area. This would bring high 60s to mid 70s along 

the coast and high 80s to mid 90s to west side valleys. East of the 

Cascades would see temperatures in the mid to high 80s. A zonal flow 

pattern could keep uneventful seasonal conditions in place beyond 

next weekend. -TAD

.AVIATION...28/18Z TAFs...VFR levels continue across northern 

California and southern Oregon this morning. Clouds moving over the 

area from north to south are generally densest over Douglas and Coos 

counties, where 20-40% chances for light rain showers continue 

through the day. Cloud coverage decreases east of the Cascades and 

into northern California. Shower chances look to dissipate by 

tonight. -TAD

.MARINE...Updated 100 PM PDT Sunday, June 28, 2026...North 

winds continue to maintain strengthen today, and will result in very 

steep and hazardous seas from Gold Beach southward this afternoon 

and evening. North of these areas, incoming swell and north winds 

will maintain steep seas. A brief period of gale force gusts are 

possible south of Brookings and within 20 nm from shore today. This 

pattern will further strengthen Monday through Tuesday evening, with 

gales likely south of Nesika Beach. Elsewhere, northerly winds and 

strengthening northwest swell may continue steep seas through Tuesday 

evening and potentially into Wednesday. Winds ease slightly with 

improving conditions late in the week.
