MAINE, USA — Like the Grinch, Mother Nature will try to steal Christmas with a nasty storm of heavy rain and strong wind. The jetstream will carve and dig deep into the Southern US Thursday guiding warm temps and deep moisture up the East Coast. A strong pressure gradient develops between a departing high and approaching cold front. A low-level jet will direct strong wind gusts into New England.
There will be a period of tropical downpours with potential thunder late Thursday night through Christmas morning. An inch or more of rain is likely at this time. Warm temps will melt a lot of snow and streams and rivers will need to be monitored for flooding. Street drainage flooding issues are also possible with basement flooding a concern too.
The wind is the biggest threat at this time, however. Surface winds could be maximized within the convective downpours on Christmas morning. Gusts may top 50 mph, potentially knocking out power.
