Larry Cosgrove weighs in... In what seems like an eternally bearish energy trading environment, a beacon of hope for more widespread wintry conditions... There are two issues to deal with for looking at the possibility of a back-loaded winter developing. One is the recurrent, broad, and strong subtropical jet stream, which continues to carry abundant energy and moisture from the equatorial regions into the western U.S. There is near-complete agreement from the computer schemes that this feature will eject three disturbances into the lower High Plains between now and Feb 5. The first, visible now on this satellite image, seems to be in the weak to moderate category. But the succeeding impulses look to have better dynamics to work with, and may trigger more and varied precipitation in the lower 48 states. Then there is the matter of snow cover. Despite repetitive cases of milder-than-normal readings in North America, the snowpack remains resilient and has actually pressed southward. If the storm sequence mentioned gets stronger, cold air pooling over the snow will be pulled southward. You will note that the CFS and ECMWF weekly outlines turn mild West vs. cold East as we move deeper into February. Yes, those schemes have had their issues so far this season. But there are reasons for a cold finish to winter.
