Walt Disney World Weather Report for December 21st from @WDW_Weather

One more really nice (albeit warm day) before some more clouds roll in and the chance for showers impacts the weekend. Highs will once again be considerably above average and will top out somewhere in the low 80s.  Fog may develop overnight for the morning – but the low tonight will remain in the low 60s.  If I had to give you a temperature for say Wishes and Illuminations I would go with somewhere in the upper 60s (translation – really comfortable).

If you are flying in from the northeast plan on a couple of travel delays thanks to some rather heavy rainfall.
