Rain will become likely today as low pressure draws closer from Arizona. High resolution models suggest we will stay mostly dry through about 1 PM, aside from a stray shower. After 1 PM, rain will begin increasing, especially over the mountains and right along I-25. Rain over the Southeastern Plains will likely be in the form of scattered showers and thunderstorms, which means not all areas will see rain. Rainfall totals will likely be in the 0.25" to 0.50" range, though in some cases rainfall could go over an inch. It's important to remember that while the large-scale pattern does favor widespread heavy rain for much of Southeastern Colorado, local wind features associated with the terrain can make forecast exact locations of heavy rain and rainfall totals very difficult. Also remember the rain will not be constant. It will come in waves, so there will be breaks. That's especially true during the late night and early mornings.
Temperatures will be held down in the 60's and 70's area-wide, except in the Southeastern Plains where highs will be in the mid-to-upper 80's.
The large-scale pattern that favors widespread rain for much of our area will continue through Thursday. Again, small scale wind features due to terrain can make the exactness of the forecast extremely difficult.
