Will the highest temperature in Shanghai be 31°C on May 12?

Analysis

When forecasters can't agree, the smart bet is on the number they're NOT all pointing at. CMA is holding firm at 31°C, but Weather Channel caps at 28°C and AccuWeather lands at 29°C — a three-degree spread on a market that pays out on exactly one rounded integer. The atmosphere isn't cooperating either. Heavy overnight cloud, dew points near 20°C, and the threat of midday thunderstorms all put a natural ceiling on the afternoon climb. Morning overcast kills the early heating you need to push into the low 30s. Then there's the Pudong factor. The airport station that actually settles this market tends to run cooler than the city core thanks to marine influence — a headline forecast built on urban models can easily overstate what the resolving station records. The most honest read puts the likely peak at 29 or 30°C. Getting to 31°C needs everything to line up: CMA nails it, the storms stay away, and Pudong behaves like downtown. That's too many moving parts. Fade the 31°C bucket — the majority of forecasters are pointing you cooler, and there's nothing in the setup that gives you reason to argue back.
