Boise, Idaho – Residents in and around Boise are in for a holiday surprise, as the National Weather Service (NWS) forecasts unusually warm temperatures for both Christmas Eve and Christmas Day. Several areas in the Treasure Valley could potentially set all-time record highs, a rare occurrence for late December in Idaho.
Along with the warmth, forecasters are warning of gusty winds and spotty showers, making it a mix of pleasant temperatures and winter weather hazards.
Christmas Eve Could Tie or Break Records
On Wednesday, December 24, Boise is forecasted to reach a high of 59 degrees, which could tie the existing all-time record set back in 1885. If temperatures rise even one degree above this level, it would establish a new all-time record high for the city on Christmas Eve. This would mark a significant anomaly for the area, where average December highs typically linger in the mid-30s to low 40s.
Nearby regions are also experiencing record-challenging warmth. Twin Falls, for example, is already forecasted to surpass its previous record high of 49 degrees, set in 2013, with temperatures expected to approach 58 degrees. Forecasters note that several smaller towns in the Treasure Valley are in similar situations, with potential record-breaking temperatures predicted not just for Boise, but across the surrounding region.
Christmas Day Continues the Warm Pattern
The forecast suggests that the unusually warm trend will persist on Christmas Day, Thursday, December 25, providing a rare warm holiday for Idaho residents. Highs in Boise are expected to remain in the upper 50s, while areas as far north as McCall could see highs near 43 degrees, exceeding the previous record of 42 degrees set in 2005.
These elevated temperatures are expected to remain above seasonal norms, offering the possibility of comfortable outdoor holiday activities, such as walks, hikes, or visits with family. However, forecasters caution that while temperatures will feel mild, the holiday weekend is not entirely free from hazards.
Gusty Winds and Spotty Showers Expected
In addition to the warmth, the Treasure Valley will experience gusty winds throughout Wednesday, particularly in exposed areas and along ridges. Spotty showers are expected to develop at times, primarily moving through the region from the west and southwest, continuing into Friday. Drivers and pedestrians should remain alert, as gusty winds can reduce visibility and create hazardous driving conditions in open areas.
Forecasters also advise that while outdoor activities are possible, residents should secure outdoor decorations, loose objects, and holiday displays, as strong wind gusts may cause damage.
Record Warmth in Historical Context
Meteorologists say that the potential for record-breaking warmth this Christmas is unusual for Idaho. Boise’s historical December records rarely exceed the mid-50s, and temperatures approaching 60 degrees represent a significant deviation from the norm.
The combination of record warmth and gusty winds is not just notable for residents’ holiday plans, but also has implications for local ecosystems and winter sports conditions. Snowpack in the mountains may see minor melting, and rivers could experience slightly elevated flows as a result of the mild spell.
Holiday Safety Recommendations
The National Weather Service urges residents to:
- Monitor local forecasts for updates on temperature and wind conditions
- Exercise caution while driving in gusty conditions
- Secure outdoor decorations and loose objects
- Be aware of spotty showers that may make roads slippery
Even with unusually warm temperatures, Idaho’s winter hazards are not entirely gone, and preparation is key to a safe and enjoyable holiday.
