A strong ridge of high pressure will build over Northern New Mexico and the Texas Panhandle this week. This will lead to increasingly warm weather through the end of this week and likely continuing into early next week. Summer ridges in this region generally indicate a very warm air mass, and this one is expected to last for a good portion of July. Some isolated late afternoon and evening thunderstorms may take the edge of the heat locally, but in general very warm and dry weather is in the forecast. Temperatures over the lower Arkansas Valley are expected to remain in the upper 90s and probably reach or exceed 100 degrees in many locations, especially toward the end of the week and into the weekend. From Climate records, June 26 is the median day when it first hits 100 degrees in Pueblo, and WFO Pueblo is currently forecasting the first of possibly several days of 100 degree weather this weekend. It will be quite comfortable in the mountains, with temperatures in the 60s and 70s. The below graphic is the Climate Prediction Center's 6-10 and 8-14 day outlook for the United States; note the expectation for well-above average temperatures over the Southern Rockies for the next couple of weeks. It certainly looks as though Summer is here for a while in Southeastern Colorado--enjoy the heat!
