As I mentioned yesterday, the updated monthly ECMWF long-range forecast model was just released to our in-house systems here at AccuWeather.
The model now goes out through January 2014. Keep in mind, the skill level diminishes greatly from the second month on, so please take this with a grain of salt, especially from October through January. Temperature anomaly forecast skill is also higher than precipitation.
Below are some of the highlights from this latest forecast by month....
--Warmer than normal for BC and the northern Prairies, including Newfoundland.
--Hotter than normal for southern U.S. Plains.
--Slightly wetter for the St. Lawrence Valley and Newfoundland.
--Drier in northern Ontario.
--Drier than normal for Gulf of Mexico, Florida.
--Much above-normal temperatures for most of eastern Canada.
--Much wetter for western BC.
--Wetter than normal for Manitoba and northwestern Ontario.
--Drier than normal from Nova Scotia to Newfoundland.
--Drier than normal along Texas coast and into Caribbean (lower tropical activity??).
