Plaincast — the National Weather Service forecast, decoded into plain English

Plaincast

What the forecast actually says — NWS Area Forecast Discussions, decoded into plain English.

Plaincast decodes the National Weather Service's Area Forecast Discussion — the real forecast, written 3 to 4 times a day by the meteorologist on shift — into plain English. The discussion is where a forecaster explains their reasoning: which models disagree, what they are watching, and how confident they are. Below is the current edition for Pueblo, with its shorthand expanded. The full experience — an AI plain-English summary beside the annotated original — loads with JavaScript, and every one of the 68 forecast offices has its own edition.

Messages

Dry and warm today, with spotty critical fire weather conditions over and near portions of the higher terrain.

Temperatures ebb and flow through early next week with a slow increase in precipitation chances.

Cooler and wetter for the middle and end of the next week.

Short Term

Current water vapor imagery and upper air analysis indicates modest westerly flow in place across the region, with the center of a large upper high in place across the Desert Southwest, as occasional embedded waves translate through the stronger zonal flow across the Northern Tier. GOES blended total precipitable water imagery indicates very dry air in place across the eastern Great Basin into western and central Colorado, where current dew pts are in the teens and 20s, and even in the single digits (9F and 8F) at the Saguache and Leadville airports at this time. Water vapor imagery does indicate another slug of sub-tropical/monsoonal moisture in place across the Baja of California into the western Great Basin region at this time.

For today and tonight, westerly flow aloft increases through the day, as embedded waves continue to translate across the Intermountain West and into the Northern Rockies tonight. The embedded dry air mixes across the higher terrain into the I-25 Corridor and plains through the day, while mid level moisture slowly increases across western Colorado, leading to some convective clouds over and near the higher terrain for the late afternoon into the early evening. Westerly afternoon breezes for areas over and near the higher terrain will develop spotty critical fire weather conditions, mainly across the Central Mountains into the mid and upper Arkansas river valley and portions of the San Luis Valley. However, conditions are not widespread enough for any fire weather highlights at this time. Temperatures are expected to by some 5 to 10 degrees above seasonal norms, with highs mainly in the 90s across the plains, and in the 60s, 70s and 80s across the higher terrain. Clearing skies through the evening will lead to seasonal lows in the 50s to low 60s across the plains, and mainly 30s and 40s across the higher terrain.
