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...26/00Z TAFs

A front moving onshore this evening will bring light rain with IFR to LIFR conditions along the coast into Friday.

For areas south of the Umpqua Divide and east of the Cascades, gusty west to northwest breezes will persist through this evening. Gusts to 20 mph will be common around the Rogue Valley, but could reach 30 mph over the East Side.

All inland areas will remain VFR this evening, then ceilings will gradually lower, but remain VFR into Friday. The exception is that areas of MVFR ceilings and rain showers are expected to spread into the Umpqua Valley after 06Z this evening, and continue through Friday. This also will include obscuration of the southern Oregon Cascades after 06Z this evening and also the Siskiyou Mountains by Friday morning.

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.
