A comparison between the Climate Impact Company constructed analog and NOAA/CPC probabilistic forecast for meteorological winter 2023-24 is, not surprisingly, reasonably similar. NOAA/CPC expands drought in the West-central/Central U.S. this autumn season. The Southeast/East Coast are at risk of tropical cyclone strikes the next couple months.

The North Atlantic basin is becoming ripe for a sudden uptick in tropical cyclone activity after Ernesto. ECMWF indicates many ALERTS for tropical cyclone development for later in August to mid-September. During this time, several to as many as 5 hurricanes may emerge.

Extreme rain has been produced by an unusual weather system on the East Coast of Australia during the past 1-2 days. An elongated cold front stretching northward from a polar vortex south of New Zealand joined forces with an inverted subtropical low-pressure trough off the Queensland Coast to produce an excessive rainfall event affecting Coastal Queensland and Coastal New South Wales.

Verification for July 2024 CDD for selected Europe cities were, on average, warmer than forecast. The strongest (warm) anomalies were in Vienna and Milan although Paris, Berlin, and Munich were each moderately warmer than normal. The Europe-East forecast maintains the warmer than normal signature.
