A Flash Flood Watch continues until 8pm MT Thursday for El Paso and Teller counties. The threat for thunderstorms, some could be strong, will continue through the evening.
There is plenty of moisture in the low levels of the atmosphere. That combined with a moderate amount of instability and slow winds aloft will allow thunderstorms to not move quickly. The slow movement and high amount of moisture in the atmosphere means that the thunderstorms could produce heavy downpours.
Thunderstorms should beging to diminish after 9pm MT. Overnight skies will remain partly cloudy. Low temperatures will drop to the 60°s across most of southern Colorado.
There will be a chance of isolated thunderstorms over the mountains and near the Palmer Divide Friday. Otherwise, most of southeast Colorado will have mostly sunny skies. High temperatures will be in the upper 80°s to upper 90°s.
An upper-level high pressure dome will be centered over the central United States for the weekend and next week. As long as southern Colorado remains under the influence of the upper-high, temperatures will remain 6°-10° above normal. Expect to see high temperatures in the 90°s with a few 100°s not out of the question, especially in southeast Colorado. - Meteorologist John Dissauer
