KEY MESSAGES

  • An active weather pattern early next week will bring rain and breezy conditions to the region, including on Election Day.

SHORT TERM

THROUGH SUNDAY · Issued at 215 PM CDT Sat Oct 31 2026

A weak mid-level shortwave trough will drift across the Mid to Upper Mississippi Valley region today through Sunday. This system may result in occasional patchy light rain or sprinkles at times. However, forcing for ascent will be limited and rainfall amounts will remain light with only a trace to possibly a few hundredths anticipated. Temperatures this evening for trick-or-treat activities will be holding in the low/mid 50s north to upper 50s/low 60s central and south. For Sunday, a seasonably mild day is expected with highs in the mid 60s for most areas.

LONG TERM

SUNDAY NIGHT THROUGH FRIDAY · Issued at 215 PM CDT Sat Oct 31 2026

Forecast focus remains on the evolution of a longwave trough early next week into Wednesday. A synoptically driven mid-latitude system is progged with a Colorado low deepening as it tracks into the Great Plains on Monday. Impressive moisture transport ahead of this system is expected with PW values around 1.5" or near the 99th percentile and a daily max for Nov 2nd. NBM precip chances ramp up Monday PM into Tuesday (50-90%) as the upper low pushes out of the Southern Rockies into the Central Plains. Well above normal highs in the mid 60s/low 70s are forecast for Monday/Tuesday, which is still 5-10 degrees below records. It will also be breezy with southeast to south winds gusting 20-30 mph. For rainfall potential, the NBM 72-hr exceedance probabilities of 1" ending 12z Thursday remain around 50-80% for most locations.

Wednesday onward, behind the main synoptic system there will be periodic lower end chances for rain, but amounts should be under a quarter inch. Temperatures will be slightly cooler with highs in the 60s and lows in the 40s, albeit still above normal for early November.

AVIATION

18Z TAFS THROUGH 18Z SUNDAY · Issued at 1145 AM CDT Sat Oct 31 2026

Occasional patchy light rain or sprinkles are possible today, but with little in the way of measurable precipitation. Overcast skies (ceilings between 4000-10000 ft AGL) can be expected through tonight into Sunday AM, with prevailing VFR anticipated.

Help & About

Forecast discussions

Each National Weather Service forecast office writes an Area Forecast Discussion: the forecasters' own account of the reasoning behind the forecast. It says what the weather models show and where they disagree, how confident the forecasters are, and what could change.

Offices issue one at least twice a day, early morning and afternoon, and update it as things change. It's written in sections, usually a synopsis, the near and long term, and the outlook for pilots, mariners and fire weather, ending with any watches, warnings and advisories in effect. Forecasters write in a shorthand of their own; the NWS glossary explains most of it.

Reading them here

  • Choose an office from the list or the map to read its latest discussion.
  • Search by city, state or office code, and sort the list A–Z or by distance, which asks for your location.
  • Above each discussion is the forecast where you are, once you've shared your location. Switch it to the forecast at the office.
  • Signed in, follow the offices you read most to keep them under Following.
  • A discussion's product header has the details of its bulletin, and a badge marks one the office has sent again with corrections.

With your AI assistant

The offices, their discussions, forecasts and alerts are also an MCP server, so an assistant like Claude can read them for you. It needs no sign-in and changes nothing. Its address is 

https://wxd.app/mcp
  • In Claude, under Settings, then Connectors, add a custom connector with that address.
  • In Claude Code, run claude mcp add --transport http forecast-discussions https://wxd.app/mcp.
  • In another client, add a server reached over streamable HTTP at that address.

Then ask, say, what the Tucson office thinks of the weekend.
