It's the longest day of the year, the summer solstice. And it is hot today. But our hottest days are still ahead, even though the days will start getting shorter. This is because of a climate idea called environmental lag. Earth has seasons because it's tilted 23 and a half degrees on its axis. As it orbits the Sun, the amount of light hitting us here in Colorado Springs changes. On the summer solstice, our half of the world, the Northern Hemisphere, is tilted directly toward the sun.

Today’s Forecast:The sizzle is on in southern Colorado this Father's Day weekend as a large and fairly strong ridge of high pressure moves north over the next several days. It will be hot today, with highs climbing to the 90s outside of the mountains. We're also closing in on the summer solstice, when the sun angle reaches highest in the sky. So, our UV index today will peak at a 12 - which means sunburn times will be very fast.

Today’s Forecast:High pressure is driving the weather bus heading into Father's Day weekend, and it's leading to warming temperatures. It will be very warm today, and hot this weekend. But just to put our heat into perspective, it was much hotter last year - today's record high of 97 was set in 2024 in Colorado Springs, and the record of 103 in Pueblo was also set just last year. We still have modest moisture around today.

Half a million bolts of lightning hit the ground in Colorado each year. And when a thunderstorm is moving through southern Colorado, you'll see the First Alert 5 team showing you those lightning strikes on radar. But lightning detection doesn't use radar. Instead, we rely on a system of radio antennas, like the one in this photo. And yes, these are similar to the radio antennas in your car. A lightning strike is nature's dramatic way of restoring balance.

Today’s Forecast:Wet roads to start the morning in the Pikes Peak Region following some weak overnight showers. The main story today though is a pattern change bringing in warmer temperatures and drier skies. While we do love rain here in southern Colorado, we've had plenty of it in the past few weeks and we're in good shape on moisture at the moment. Today, northwesterly upper level winds will bring weak moisture and energy through our skies in the afternoon.
