Light snow continues to fall across the Cascades and the Siskiyous this morning. Not expecting any travel related issues. Here are the Crater Lake Steel Visitor Center and Mt. Ashland Lodge webcams.

Regional Air Quality and Upper Level Smoke Mapping 10/27/26 6 AM The first graphic shows the HRRR smoke modeling of upper level smoke and where it will be positioned by later this afternoon. The second graphic indicates the current air quality levels.

Highs today will remain below normal for this time of year. Most areas will be around 10-15 degrees below normal. Here is a look at the latest GFS model run projections.

We remain under a trough this morning with the potential for more lighter rainfall along the coast and inland locations later this afternoon. The low will continue to track east. Snow levels remain around 5,000 feet in elevation.

We could see light snowfall develop later in the week across portions of our region. Here is the NWS Medford snowfall forecast for higher elevations mainly above 5000 ft.

Another cool day is in store for the region as we remain under a trough and cooler air filters in behind the cold front. Highs will trend below normal based off the GFS model run.

With this incoming front we could see cold enough air to allow snow levels to drop to around 5,000 feet in elevation. Light snow is possible at Crater Lake National Park. Here are the latest estimates from the NWS Medford.

The airmass satellite imagery shows the low just offshore to our northwest. The front will progress inland later tomorrow. We will see clouds increase as it tracks to the southeast.

The European model is showing a wetter close out to the last week of October. Halloween is looking to be wet. The heaviest precipitation will be focused along the coast and into northwest Oregon and Washington.

Clear skies overnight have allowed temperatures to quickly drop overnight. Visible satellite imagery is only showing a few areas of high and mid level clouds off to the northwest as a new front approaches.

Precipitation estimates from the GFS model run indicate where we will see the heaviest precipitation develop heading into Sunday through Monday of next week. Our region looks to be on the southern edge of the more significant rainfall amounts.

It is going to be quite cold overnight across the region. Here is a look at what the GFS model is forecasting for lows. Widespread frost and freeze conditions are expected to develop.

The frontal boundary is now well off to the east. We are seeing areas of fog and low clouds across some of the western interior valleys. It is denser where some measurable precipitation was observed.

Updated European weather model accumulated precipitation estimates from now through late Tuesday 10/27. The bulk of the rainfall will arrive late Sunday into Monday of next week.

The 24 hour observed precipitation amounts show where the heaviest rainfall has been focused across the region. Northern California continues to be the focus as the low tracks to the southeast.

With colder air beginning to filter into the region today into this weekend we can expect to see frost and freeze conditions develop across the forecast area. This could begin as early as tonight for some west side valley locations.

As the center of the low continued to track to the southeast overnight we are seeing areas of showers develop across portions of the region. These are circulating counter clockwise around the low.

Frost and freeze conditions still look likely to develop on Friday night into Saturday morning. Many of the western interior valleys will see the potential for frost and damage to sensitive plants.

Updated precipitation estimates across the region based off the GFS model run. The heaviest precipitation about will be from thunderstorms that develop later in the day.

The Storm Prediction Center at NOAA has issued a general thunderstorm risk area in light green for today. This covers areas east of the Cascades and into portions of Siskiyou and Modoc counties.

Here is a look at the latest surface high temperatures across the region. We will warm up a few more degrees today with highs trending above normal for this time of year.

The low is tracking south into Northern California this morning. We are seeing clouds as well as some showers developing. Instability aloft later this afternoon and evening could generate a few thunderstorms mostly east of the Cascades.

The next low is developing off to our southwest. This will act as the trigger for afternoon and evening thunderstorms as it tracks inland into Northern California.
