DISCUSSION

Issued at 1212 PM CDT Sat Oct 31 2026

Above normal temperatures and mostly dry conditions are expected for Halloween festivities and Sunday into early Tuesday. A potent low pressure system swings through the Southern Plans Monday into Tuesday, kicking up a warm and breezy Monday, before sending a cold front through Deep South Texas on Tuesday with cooler temperatures and a brief medium (30-40 percent) chance of rain into Wednesday. Near normal temperatures are expected Thursday into the weekend. Another frontal boundary attempts a southern run late Friday through Saturday, with another brief low to medium (20-30 percent) chance of rain Friday and Saturday. Overall, rather seasonal conditions are expected to kick off the first week of November.

Persistent easterly flow across the Gulf and elevated astronomical tides continue to narrow beaches during high tide cycles through the weekend with conditions expected to improve Sunday into Monday. A Coastal Flood Statement is in effect through tonight. Patchy to dense fog developed last night across the ranchlands and may develop again tonight with light to near calm winds. Cloud cover may prevent any dense fog from developing or settling in.

AVIATION

18Z TAFS · Issued at 1212 PM CDT Sat Oct 31 2026

VFR conditions are expected to generally prevail through the TAF period, with a southeasterly breeze this afternoon and patchy fog expected late tonight.

MARINE

Issued at 1212 PM CDT Sat Oct 31 2026

Marine conditions continue to improve through the remainder of this weekend into early next week. Breezy winds across the bay may bring a brief period of Small Craft Caution conditions Monday afternoon. A cold front on Tuesday with breezy northerly winds may also kick up occasional SCEC conditions across the Gulf. Light onshore flow returns late week with another frontal boundary possible next weekend. The best chance of showers or isolated thunderstorms occurs with the frontal passage Tuesday evening through Tuesday night.

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.
