Evening weather forecast for June 20: Astronomical summer starts Tuesday and a stretch of dry summer

Описание: Today is the last day of Spring. Summer officially arrives early Tuesday morning, marked by the summer solstice occurring at 3:14 AM MDT. As if right on cue, summer weather will also settle in for the rest of the week, with dry and much warmer conditions.

The summer solstice is the longest day of the year, with 15 hours and 26 minutes of daylight. The sunrise in Boise will be at 6:03 a.m., with the Sun staying up until 9:29 p.m. After the summer solstice, we will very slowly see a decrease in daylight, as we head toward the autumnal equinox on September 22nd.

The summer solstice marks the northern-most point of the Sun's direct energy at 23.5° north of the Equator, also known as the Tropic of Cancer. It's also the North Pole's point of maximum tilt. This means that the Sun's warming and burning power is at its strongest tomorrow -- and over the next several weeks. Slather on the sunscreen, and limit sun exposure between 10:00 a.m. and 4:00 p.m.

Temperatures on Tuesday will rise to average levels for the date, with low and mid 80's expected for the Treasure Valley. Highs will be up to around 90° on Wednesday, under sunny skies. With a brush from some cooler air to our north, temps will "cool" just a touch on Thursday and Friday, with highs in the mid 80's. Expect breezy conditions both days.

Next weekend will be the summer weekend we've all been waiting for! Valley lows will be around 60°, with highs in the low to mid 90's.
