What the forecast actually says

What is an Area Forecast Discussion?

Area Forecast Discussions are the real forecasts, written 3 to 4 times daily by NWS meteorologists reading the models and interpreting what they mean for your area. They offer far deeper insight than any weather app, but they're written in dense meteorological shorthand. Plaincast uses Anthropic's Claude to summarize them into plain English, side by side with the annotated original.

Synopsis

Hot temperatures will continue for the next week along with daily chances of afternoon and evening showers and thunderstorms.

Discussion

Ahh the monsoon. It never fails that what looks like an active day 24 to 48 hours out in the model world ends up to be much less. Today is a good example as drier air has punched in from the east with no storms on radar as of 230 pm. The CAMs are also been struggling today. Although its been a slow start to the convection, still looking at widely scattered storms developing in the 3-5 pm with generally movement to the west northwest into this evening. Main threat from any storm will be strong gusty winds, brief heavy rain and blowing dust.

Enough moisture will be around for the next 7 days for daily chances of showers and thunderstorms with day-to-day variability on areal coverage of storms.

High temperatures so far this afternoon have been in the upper 90s east to the 109 lower deserts. Extreme Heat Warning remains in effect until 8 pm this evening. Slightly cooler tomorrow with above normal high temperatures continuing all next week with the end of next week seeing highs like we have seen yesterday and today.
