Warmer than normal pattern to close out Summer 2026

Bend, Ore (KTVZ) – The mercury in the thermometer will once again top out in the 80s as we did over the weekend. Saturday the mercury hit a high of 81 and Sunday we topped out at 86. The last weekend of summer 2026 will be defined by a summer-like feel and we will maintain the above normal warmth through Thursday.

Tuesday will be mild and dry as afternoon high temperatures return to more seasonable ranges. Highs in Bend and Redmond will be around 75° with La Pine and Sisters hitting the low 70s.

Autumn officially begins at 5:05 pm Tuesday as the direct rays of the sun will be over the equator, (autumnal equinox) continuing their journey south to the Tropic of Capricorn. Equal parts daylight and darkness is also on the equinox.  The daylight hours be less than the nighttime hours beginning on Wednesday.

Wednesday will be another partly to mostly sunny day with high a few degrees cooler than Tuesday.  The afternoon high in Bend will be 74, which is the normal or average high for the 23^rd of September. Winds will be light and variable.

Thursday will bring back some of the warmth to Central Oregon as a cold front approaches. The southwest flow ahead of the front will allow the mercury to rise into the upper 70s and possibly the low 80s Thursday. This will also increase the wind speeds slightly so a breezy day is also in the cards.

Friday will see the passage of the front and associated moisture. I am expecting to see rain develop before the sun rises Friday and impact the morning commute. The rain will be light and widespread most of the morning and will begin to taper off as the front passes by early afternoon.

Highs on Friday will be lower than normal, only reaching the low to middle 60s.

Saturday and Sunday will also be on the cool side as high pressure keeps the region quiet and dry.

Please, Stay safe and smart.
