Area of low pressure still churning over the state, currently over southeastern Colorado today. With the system again overhead, we will see the threat of thunderstorms returning to the High Country, as well as the Plains over southeastern Colorado. Over the Denver Metro and Boulder, only a slight chance of storms, as the system will be to our south, keeping …

Not much change in the overall pattern for today. A large dome of high pressure remains across Colorado. One change that has happened, however, is a weak low pressure circulation across southwestern Colorado. This small scale circulation is embedded in the large dome of high pressure (see below).
