Tonight’s Forecast:

** FLASH FLOOD WATCH for SANGRE DE CRISTO MOUNTAINS, WET MOUNTAINS, RATON MESA until 3AM MONDAY **

There is an exceptional amount of moisture in Southern Colorado. With the passing of a cold front yesterday, we now have Easterly winds pushing all of that moisture up against the mountains. That will lead to strong thunderstorm development for this evening. These storms will be capable of producing heavy rainfall, strong gusty winds, and small hail. The greatest threat from this is likely to be the heavy rainfall, which is why there is a Flash Flood Watch for the Sangre de Cristo & Wet Mountains along with the Raton Mesa. The Eastern Plains look to miss out on the majority of the thunderstorms for Sunday, but the I-25 corridor should keep a close eye. These storms will come together to form a mesoscale convective system (MCS), or a large group of organized thunderstorms. The MCS will likely move south towards the New Mexico border into the overnight before eventually dying off.

Monday will be MUCH cooler than the past few days, with highs only in the 70s for the Pikes Peak Region and lower 80s for Pueblo. High pressure works down in from Canada and will not only bring cooler air, but once again push that moisture up against the mountains and fire off another round of storms.

Extended Outlook:

Tuesday and Wednesday look to bring a warm up in our afternoon high temperatures, but also a chance for an afternoon shower or T’storm. The majority of the thunderstorm activity should be held to the mountains for the middle part of the week. On Thursday, another powerful system will rumble through the state and bring a greater chance for late day showers and storms. Those chances will stay with us through to next weekend before finally clearing out next Sunday.
