HEADLINE: U.S. WEATHER MILD AND FAIRLY QUIET OVER NEXT 10 DAYS, NORTHERN BRAZIL TRENDS A BIT WETTER…
North America: The mid-day GFS is similar to the last several runs, with little/no rainfall from TX Panhandle north to the Dakotas through day 10, and 1-2″ of rain south of a line from Oklahoma City to Springfield, primarily with a days 2-4 rain chance.
South America: This run is a little quicker to return more rain chances close to climo in north central Brazil around day 10 and is otherwise little changed.
Note: Due to the arrival of my second child tomorrow morning, WeatherTiger forecast product issuance will be suspended 12/13 through 12/22. We anticipate a return to normal forecast delivery schedules during Christmas week. See you all on the other side!
