Sunday Weather: More Afternoon Showers

Temperatures this morning were the coolest I have seen in about a week. We had a lot of 40's early. Dewpoint temperatures are starting to drop, which means humidity is decreasing as moisture in the atmosphere becomes less abundant. Lower humidity to feed the afternoon upslope breeze means showers will be less abundant.

The upper level low pressure circulation is moving through southern Colorado and northern New Mexico this morning. Rain and high-elevation snow have been falling over southwestern Colorado behind the low. In our area, we have been dry. The upper low could still provide a few showers to us this afternoon, but we will be growing more dependant on the afternoon upslope breeze to generate the showers. With the primary source for lift being topography-dependant, showers likely will become more restricted to areas in or near the mountains. Humidity will also be on a downward trend beginning today, which means even those showers and thunderstorms that develop in or near the mountains will become less abundant. Expect high temperatures in the 60's and 70's today and tomorrow with 80's beginning to return to the Plains. A bigger warm up is on the way. I'll have those details in the seven-day forecast coming up.

A little more sun this morning will make for a more speedy warm up. By 10 AM, we're already in the 60's with 50's lingering in high elevations. Showers begin developing by noon in the mountains west of I-25, and temperatures will warm into the 70's along the Arkansas Valley and Southeastern Plains with 60's around Colorado Springs and in high elevations. By 4 PM, a few showers try to escape the mountains, but they will be much less abundant today than they have been.

The coverage of showers will continue decreasing tomorrow as humidity continues to drop off. Just enough of an upslope breeze will stay with us, however, that a stray afternoon shower cannot be completely removed from the forecast in and near the mountains. The farther away you are from the mountains, however, the less likely you are to see any rain. Lower humidity with fewer clouds and showers will also mean a warm up, which really revs up on Tuesday. That's when we will warm back into the 80's, and some areas will even make a run toward 90. The next chance for any rain comes on Friday when a system over the Pacific Ocean this morning approaches.
