Thereafter, the next cold front charges southeast and spreads another round of below-average temperatures through all states east of the Rockies this weekend into Monday. Some locations will be 10 to 20 degrees below late-March averages. Computer model guidance shows that another reinforcing surge of cold air will arrive in the Midwest and East during the early to middle part of next week. The culprit for the persistently cold weather this winter, now lasting into the start of spring, is a tendency for the jet stream to dip southward repeatedly to the east of the Rockies. This has allowed bouts of Arctic air to pour into the central and eastern United States. With the jet stream poking northward to the west of the Rockies, residents of California and the Southwest have seen persistently mild temperatures this winter. More of the same is expected there, with high probabilities of above-average warmth forecast to start the spring. Winter Storm Next Week? Although we are very confident in the forecast for below-average temperatures this weekend into next week, we have much less confidence in whether a storm system will tap into this cold air and produce significant winter weather in the East. While still nearly a week away, some computer models have suggested at times in the last day or so that there is a possibility of a strong coastal storm with wind, rain and/or snow affecting portions of the Eastern Seaboard as this second surge of cold air arrives. It is currently far too early to speculate on any details beyond that. In fact, its very possible that there ends up being no significant storm at all.
