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 Indianapolis, 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.
Dry yet pleasant fall weather continues through much of next week with above normal afternoon highs
Patchy fog will occur in low lying areas late night/early mornings through Sunday morning
A wetter pattern may take shape for the Halloween weekend
Quiet weather with above normal temperatures will continue through much of next week, with rain chances returning around Halloween.
Subsidence from upper ridging and surface high pressure will continue to provide dry conditions through Sunday. Winds will remain light. High clouds will spill across the ridge into the area at times.
Look for highs around 70 to the lower 70s today and in the lower to middle 70s Sunday. Lows will be in the 40s (did cut guidance for lows tonight in favored cold areas given what has happened recently).
An upper trough across southern Canada will help suppress the upper ridge south on Monday, which will allow a surface cold front to sag into central Indiana on Monday. The front won't get much farther south as upper flow will become near parallel to it. Generally only high level moisture will be available, and upper support is nowhere nearby. Thus, dry conditions will persist.
Additional upper waves moving through the flow, mainly to the northwest of the area, will bring the front back north and out of the area Tuesday into Wednesday. Again, little to no local forcing and no moisture will keep the area dry.
Highs will be in the lower to middle 70s Monday and Wednesday. Behind the front on Tuesday, highs will be around 70 to the lower 70s.
