More March Maddness

It would be a wicked March across much of the U.S. as more Pacific storms are getting together in the tropical regions and could be big weather makers in the next two to three weeks.

These two images show two storms which are forming along a major oscillation called the Madden-Julian oscillation. This area of moist low pressure is usually active toward late February and early March for about 40 to 50 days a year. It can mostly be seen across Indonesia and sometimes even Hawaii.

Two major disturbances are forming in the Equatorial Moisture Fetch which could develop across the western U.S. within the next 10 to 15 days. These storms could very much resemble what is happening across the west right now with a strong pacific system which moved across southern California and is now moving across the Rockies.

If these two disturbances move in we could see some heavy March snow across many regions of the country and we may make up for the lack of snowfall across the Great Lakes region.
