HEADLINE: Two discrete areas of thunderstorm activity in the tropics are resulting in uncertainty on the mid-latitude pattern. One area of thunderstorm activity over the Indian Ocean is associated with a strong Madden Julian Oscillation (MJO) event. The second area of enhanced thunderstorm activity over the West-Central Pacific is associated with an atmosphere evolving towards an El Nino. If the Indian Ocean thunderstorm activity becomes the main pattern driver, it could result in less cold down across the U.S. for a brief period. But if the West Pacific thunderstorm activity continues to roar and influence the pattern, it would likely remain cold over the East.
