Rachel and I were at work looking at the radar this evening and noticed something you don’t see every day. As storms approached from the north heading southeast a gust front was noticeable moving southwest. Radar isn’t really supposed to see this, but I’ll tell you why it did.
First you have to understand these storms were tall. That means warm air from the ground was lifted high and chilled. The cold air was more dense than its surroundings and began to drop like a rock! At ground level it’s a cool and dry breeze as the thunderstorm is taking aim
Not many reports of wind damage, so it was probably a moderate gust in the 30-40 mph range. Just an educated guess.
As the cold air traveled along the ground it picked up dust, pollen and bugs. That broken and weak bowed line on the radar screen represents it.
