Springtime has been with us for 91 days and even though today is a season-shift, we have been "experiencing" a summertime pattern since the first days of May. There was only one day in May that we noticed the daytime high under the average high for a specific day. Today is the longest day of the year and designates the official start of the summer solstice. The sun is positioned at its furthest northern point and will be directly overhead at noon. Elsewhere, the warmest part of the day is after noon when the sun is highest in the sky. The heat kicks-in due to the lag-time required for the ground and water to warm. North of the Arctic Circle there’s continuous sunshine for 24 hours. Sunset in Barrow, Alaska won't occur until August 2. Along the U.S.-Canadian border the sun appears for 16.25 hours and 13.75 hours in Baton Rouge.
