Area Forecast Discussion
National Weather Service Medford OR
401 AM PDT Sun May 24 2026

.DISCUSSION...

Not much will change from Saturday as the upper air pattern
remains zonal with some weak embedded short waves. Just like
yesterday, we had to increase PoPs and the chance of thunder to
get some mention of thunderstorms in the forecast around northern
California. Any storms or showers that do from will be isolated
and fairly weak with limited lightning activity. In any case, it
will be another warm day as highs push into the 80's and perhaps
90 here in Medford. We've hit that 90 degree mark the last few
days at the office.

The weather pattern really begins to change on Monday as a deeper
trough in the Pacific approaches the coast on Monday morning. In
addition, a well defined cold front should push onshore by the
afternoon hours, which is a bit slower than what the models were
showing the last few days. The latest set of guidance shows this
front bringing wetting rain to the coast, although it will be
notably drier farther inland, even for some locations west of the
Cascades near the California border.

Winds remain the other topic of concern as this front moves into
Oregon. Forecast soundings continue to show deep mixing during the
afternoon hours with dry adiabatic lapse rates up to 600 mb east
of the Cascades. It looks very likely we'll mix down wind gusts
around 40 mph with some areas gusting to 45 mph. The extreme
forecast index(EFI) also made a concerning tick upwards with the
0Z ensemble run Saturday evening. It's now highlighting EFI wind
gust values of 0.99 to 0.90 across our forecast area. Values this
high denotes the ensemble wind gust forecast exceeding model
climatology for the time of year, which is unusual. Another
concern is the shift of tails around 1-2, which suggests about 10%
of the ensemble members are predicting wind gusts in the extreme
of model climatology for late May.

So what does this all mean for impacts? Wind gusts this strong
could produce isolated power outages. Also, any events outdoors
should plan for some stronger wind gusts in the afternoon and
evening. There are also some fire weather concerns as wind gusts
mixed with low relative humidity farther to the east will increase
the fire weather risk, especially in Lake County.

Eventually, this front and trough will push through Oregon Monday
night into Tuesday and temperatures will trend significantly
cooler with highs in the lower 60's in the Rogue Valley. Thats
about a 30 degree trend lower compared to forecasted highs today.

This low will become cutoff and bring us a continued chance of
showers and perhaps some embedded thunderstorms through most of
next week. Given the cooler and wetter airmass, we're not
concerned about major weather impacts from these showers or
thunderstorms. If anything, the rain from these thunderstorms
will be beneficial given how dry it has been this Spring and
Winter.

&&

.AVIATION...24/12Z TAFS...

Late tonight and early Sunday morning, expect areas of IFR/LIFR to
redevelop along the coast, mainly from Cape Blanco northward and
from Gold Beach southward. Conditions are expected to clear to VFR
around 18z. Elsewhere, expect continued VFR.

Cumulus build ups and isolated showers and thunderstorms are
expected in Siskiyou County east-northeastward into far southern
portions of Klamath and far southeastern Lake counties.

&&

.MARINE...Updated 345 AM PDT Sunday, May 24, 2026...Gusty north
winds will keep seas steep through Sunday morning. Wave heights
will be relatively low around 6 to 8 feet at 7 seconds. A cold
front will move through the waters on Memorial Day bringing rain
and increasing seas. Seas are likely to become steep again on
Monday afternoon, with the highest probability, strongest south
winds expected to occur north of Cape Blanco. Swell dominated seas
are expected to reach a peak on Tuesday at around 13 to 16 ft at
14 seconds.

High pressure offshore and lingering low pressure inland are likely
to bring increasing north winds on Wednesday with gales possible
south of Port Orford. Gusty north winds are likely to continue steep
to very steep seas Wednesday night into Thursday while a long period
west-northwest swell builds.
