A cold front moving through Southeastern Colorado today will boost the probability of rain for all of our area, but that does not necessarily mean everyone will see the rain.
The moisture is present, though not as abundant as expected. Along a cold front, wind convergence, or blows into a central area along the cold front, and that provides an increase in the rising motion needed to generate the rain. Add to that an upslope breeze this afternoon, and the mountainous areas just west of I-25 and the Palmer Divide see an increased risk for flash flooding that includes the Waldo Canyon and Black Forest Burn Scars.
In the higher elevations where the upslope breeze influences the development of the rain, over an inch of rain could fall. Other areas along and east of I-25 will see less than a quarter-inch of rain. As mentioned, some locations could miss out on rain completely.
Temperatures will be held down a bit by the extra cloud cover and the rain. Highs will be in the upper 70's and lower 80's along the Palmer Divide with mainly 60's in Teller County. Highs will be in the mid-to-upper 80's from the Arkansas River south to the New Mexico border and west of I-25. For the Southeastern Plains, expect highs in the 90's.
