>> WE HAVE A COMMON STRATEGY, AND WE CAN'T ALWAYS SHARE THE DETAILS OF THIS STRATEGY TO THE PUBLIC, INCLUDING WHEN THE GATES OF HELL WILL BE OPENED, AS THEY SURELY WILL, IF ALL OUR HOSTAGES ARE NOT RELEASED.

HEAVY RAIN, FLOODING AND MUDSLIDES HAVE INUNDATED STATES IN THE SOUTHEAST THIS WEEKEND.

AS THAT SYSTEM MOVES OUT, MOST OF THE LOWER 48 WILL SOON FEEL THE TENTH POLAR VORTEX OF THIS WINTER SEASON.

THE NATIONAL WEATHER SERVICE FORECASTS THE FRIGID BLAST OF ARCTIC AIR WILL MOVE SOUTH THIS WEEK, PLUNGING TEMPERATURES.
