Plaincast — the National Weather Service forecast, 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 Houston, 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.

Discussion

The ridge that has been stationed over us since the first cold front of the season begins to weaken during the weekend. The pressure gradient will tighten this weekend, thus, bringing the possibility of winds around 10 mph with gusts up to 20 mph at times. Rain chances will remain low through Sunday due to precipitable water values of around 1" or less. Temperatures are still anticipated to reach the low to mid 80s inland while staying slightly cooler in the upper 70s along the coast. Increasing moisture transported from the Gulf raises the dewpoints back into the upper 50s to low 60s, decreasing our fire weather risk. Overnight lows sit between the mid 50s and low 60s inland while slightly warmer along the coast in the upper 60s and low 70s.

As we start the work week, an upper-level trough will meander south through the Plains while surface moisture continues to move in from the Mid Texas Coast, increasing precipitable water to around 1.5 inches. This is where we will see our chance of rain return, brining isolated to scattered showers mainly over areas west of I-45. Temperatures will be slightly cooler early next with highs in the upper 70s to low 80s. The overnight lows, on the other hand, are slightly warmer sitting in the 60s inland and low 70s along the coast lines. This is due to the previously mentioned additional moisture and increasing dewpoints.

Looking further ahead guidance continues to suggest a cold front dropping into the area around the Halloween time frame. But uncertain remains with the usual suspects of timing and intensity that far out in the models.
