DISCUSSION

Key Points:

* Breezy west winds in East side with breezy NW winds in the Rogue Valley and Siskiyou County through Saturday afternoon. * Showers return this afternoon and move inland overnight. * Temperatures fall below normal beginning tomorrow and continuing through the middle of next week. * There is a frost/freeze concern east of the Cascades starting in more areas Sunday morning.

The latest max wind gust observations are in the 15-25 mph range got west side valleys and east of the Cascades. While we have low pressure moving towards our area, breezy conditions will be a regular impact the next two afternoons in these locations as well. Enjoy the warm weather this afternoon while you can, because these disturbances will cool down temperatures for the next several days.

First, we need to talk about the rain chances ahead. A cold front arrives tonight, and this will bring the beginning of our rain chances that last through part of the weekend. With cooling temperatures and favorable PW values near 1" at west side sites, tonight's rain has the best chance to be more widespread. However, it will still be light overall with forecast amounts near 0.25" for the Coos County coast and Cascades and ~0.10" for west side locations and <0.10" east between tonight through Friday morning.

Although showers will focus on areas west of the Cascades, another line will develop and move into Modoc County and portions of Klamath and Lake counties. Far east side has forecast CAPEs around 100-150 J/kg Friday afternoon, and there is a 15-25% chance of lightning during this time. This chance will stay in Modoc County through the evening. Into Saturday, most of the rain chances will be west of the Cascades with isolated showers east. Leftover showers are expected Saturday night into Sunday for Coos and Douglas counties before there is some dry time.

While the cloudier skies and rain chances remain Friday, a cooldown in temperatures begins. Highs will be in the 50s/60s for the coast, upper 60s to 70s for west side valleys, and mid-/upper 60s for east side. To put it into perspective, the highs the next few days will be comparable to early/mid-May temperatures. Checking back, we haven't had highs in the 70s since June 9th for Medford and June 10th for Roseburg.

Another concern on the temperature side will be cooler nights. It will begin Friday night from an arch including the Klamath Marsh to the Fort Rock and Christmas Valleys with the potential for frost. After, a freeze concern arrives Saturday night for most areas east of the Cascades with drier conditions and clearer skies returning. Northern Klamath and Lake counties currently hold a 60-70% to reach 28 degrees or cooler Saturday night, so this will be monitored to see how much rainfall comes to that area in the coming days. Getting into early next week, east side temperatures will still be colder, but afternoon temperatures will warm to only be 5-10 degrees below normal. There could be showers Tuesday for Douglas and Coos counties. -Hermansen

AVIATION...26/06Z TAFs

A front moving onshore tonight will bring light rain with IFR to LIFR conditions along the coast into Friday. Ceilings are expected to gradually lift to IFR/MFR Friday afternoon.

MVFR ceilings and local IFR will spread into the Umpqua Valley overnight with rain persisting through Friday morning, gradually lifting with a mix of MVFR/VFR in showers Friday afternoon. Elsewhere, inland areas will remain mainly VFR through Friday except for local MVFR west of the Cascades. There is 30% chance for MVFR ceilings at Medford (KMFR) between 13-18z. Mountain obscurations will also develop tonight and persist into Friday, especially for areas from the Cascades west. Gusty afternoon winds are expected for inland areas on Friday with strongest winds east of the Cascades (gusts 20 to 30 mph).

MARINE...Updated 115 PM PDT Thursday, June 25, 2026

Winds remain relatively weak today through Saturday night, while a frontal system brings periods of light rain. But, stronger winds in the offshore waters will bring a steep, fresh west-northwest swell Friday night into Saturday night.

Northerly winds will then be stronger early next week, especially south of Gold Beach. This includes a potential for gales in the southern waters Monday afternoon through Tuesday evening.
