Today we will experience extreme weather at its finest.  Severe flash freeze is setting up to enter the region as soon as later this morning, when temperatures sweep west to east with a 20-30F temperature change in the next 18-20 hours.  It will happen suddenly with the change of the winds vector.  AS the warm balmy 50+ degree southwesterly winds will change to a violent northwest cold dry bone chilling cold arctic air howling over 30mph.  Rain will change to snow and temps will bottom out in the lower 20s.  BRRRR!!!!!!!!!Current MESO OBS
