Residents and visitors to the river corridor can anticipate pleasant, warm conditions today before a shift brings showers and noticeably cooler temperatures midweek. Highs near 80 degrees today are forecast to transition to the low 70s by Thursday, a trend expected to persist through the upcoming weekend, accompanied by rain chances and stronger winds.

This morning began with cool temperatures in the 60s. The afternoon is set to bring highs near 80 degrees, with abundant sunshine and light breezes. As evening approaches, temperatures are expected to fall through the 70s under clear and calm conditions. Overnight, low temperatures are anticipated to be in the low 60s, maintaining mainly clear and calm skies. Sunscreen is still advised between 10 a.m. and 4 p.m. for those planning to be outdoors for more than 30 minutes.

The weather pattern will begin its transition on Tuesday, with a 10 percent chance of rain in the afternoon while highs remain near 80 degrees. The probability of precipitation will increase significantly by Wednesday afternoon, reaching a 30 percent chance, and then rising to a 50 percent chance from Wednesday night through Thursday. Any rainfall from this system is expected to be localized, with amounts likely near 0.10 inches in areas experiencing passing showers. Stronger winds will also accompany this system; gusts up to 30 mph are expected from the southeast on Wednesday. Thursday will see gusts up to 25 mph, with winds shifting to come from the southwest.

Following the midweek weather system, temperatures will undergo a noticeable drop. Highs that were near 80 degrees on Tuesday and Wednesday will fall to the low 70s by Thursday, a trend forecast to continue through the upcoming weekend. Nighttime and early morning low temperatures will also become cooler, decreasing from the 60s to the 50s starting Friday, setting the stage for some distinctly cooler weekend mornings.

Beyond the temperature and rain, forecasters indicate pollen levels will be "medium" to "low" this week. Predominant pollen types include ragweed, sagebrush, and chenopods. Individuals susceptible to allergies may find relief by showering and changing clothes after outdoor activities, keeping windows closed on windy days, and regularly vacuuming and dusting. Allergy medication can also assist in managing symptoms. Sun protection remains an important consideration, particularly between 11 a.m. and 4 p.m. Wearing a hat, light-colored clothing, and applying sunscreen are advised when spending time outdoors. The UV index is expected to be strong enough between noon and 2 p.m. that a sunburn could occur within 30 minutes of exposure. Finally, the air quality forecast for today and tomorrow is moderate, primarily due to ozone levels.
