The National Weather Service issued a red flag warning for much of Southwest Idaho, including the Treasure Valley, Sunday. That means low humidity, warm temperatures and strong winds could create explosive fire potential today. The warning is in effect through 6 p.m. Monday.
All of Nevada, Utah, western Colorado, northwest Arizona, and parts of southern California also have red flag warnings.
The high temperature in Boise Sunday is forecast to be about 93 Sunday which would tie for the highest temperature of the year (June 4 was 93).
The Idaho Department of Environmental Quality issued a yellow air quality alert, indicating ozone levels will be slightly elevated Sunday and could be a health concern to a very small number of people who are sensitive to ozone.
Late this afternoon, a cold front will move through Southwest Idaho, bringing gusty winds. A wind advisory is in effect for 5 p.m. to 9 p.m. Sustained winds are expected to be 35 mph, and there may be gusts of more than 50 mph.
George Skari, a meteorologist at the National Weather Service, said the front will be dry no rain, thunder or lightning expected.
The cold front will knock down the high temperatures for the first part of the week. The highs Monday and Tuesday may reach only the lower-70s. The overnight lows will be in the 40s and 50s.
