Jul. 3--Get out the sunscreen and swimsuits.

The temperature should hit 100 on the Fourth of July for the first time this summer in the Tri-Cities.

A wave of warm air is moving across the state that should bring the high to just under 100 today under sunny skies in the Tri-Cities. After the temperature climbs to 100 on Saturday, it should cool a few degrees Sunday for a high of about 97. The weekend could end with thundershowers Sunday evening.

Even if you're traveling to Seattle for the holiday, you can expect sunny skies for most of the weekend. For Portland, the National Weather Service has issued a heat advisory with temperatures expected in the 90s there today and Saturday.

With the hot weather comes higher fire danger and the risk of heat exhaustion and heat stroke, warns the Washington State Department of Health.

It advises basic precautions, such as never leaving pets or children in a parked vehicle and drinking lots of fluids -- and that doesn't mean those with alcohol, caffeine or lots of sugar.

Save the most strenuous outdoor fun for early or late in the day at least until you build up tolerance for warmer temperatures, it advises.

The month is off to a hot start with temperatures in the Tri-Cities reaching 96 degrees Thursday at the Pasco airport and 97 at the Richland airport, according to the weather service.
