Saturday Weather Update

A Flash Flood Watch is in effect for El Paso, Pueblo, Teller, and Fremont counties and for the Wet Mountains and the Rampart Range until midnight Saturday night. The Flash Flood Watch includes, but is not limited to, the following cities: Colorado Springs, Manitou Springs, Black Forest, Pueblo, Pueblo West, Cascade, Woodland Park, Divide, Cripple Creek, Cañon City, Penrose, Florence, Wetmore, Texas Creek, Cotopaxi, and Avondale.

Weather Update: At 1pm, analysis of surface weather conditions shows weak low pressure over northern New Mexico. North of the low pressure circulation, the wind is blowing from east to west. As the wind blows upslope, it is transporting humid air upward. That vertical air motion has kept much of Southern Colorado beneath a cloud bank, though areas along and west of Interstate 25 have cleared enough to allow some sun to shine.

The upslope breeze favors the development of rain this afternoon and evening. The strongest rising motion associated with the upslope breeze will be on the eastern edge of the mountains, which brings about that potential for flash flooding. 

We know based on current weather conditions that a bout of heavy rainfall is favored. Exactly when and where is a little more tricky, but high-resolution computer models have favored heavy rainfall that will greatly increase the risk for flash flooding  over western El Paso County between 5 PM and 10 PM. That is not meant to suggest there is no flash flood risk during other times, but rather to say the 5-10 PM time frame appears to be the highest risk period. Stay with First Alert 5 on air and online for the latest weather conditions, and be prepared to take action if flash flooding threatens. Be especially weather aware if you are in areas prone to flash flooding.
