Weather

Turns out, as a matter of fact, the storm I predicted last week, is still on stage for next week. The Wednsday through Saturday time period. Where is the question. There looks to be a fairly strong storm come through the Pacific Northwest this weekend. What happens after that is very uncertain. Right now there are 3 main options. These are just the most likely ones. There are many more, less likely ones.
1) The storm splits, sends a piece of energy to the Desert Southwest, and a piece of energy across the Great Plains, to the Great Lakes. The storm ejecting to the Great Lakes drags a cold front across the U.S., with the Desert Soutwest Storm Lagging behind it, in the southern branch of the jet stream. After the cold front comes through, it then rides that storm up the Eastern Seabord.
Effects: A rapid warm up will most definetly be felt in the Eastern U.S. this coming week. Highs in the 60's will be common across the Mid- Atlantic. This is because of the warm southwest winds drawn out ahead of the cold front. The cold front comes through,brings rain, and ushers in colder air. The second storm, lags behind this one, and rides up the coast, bringin rain to south of the Mason Dixon line. (It's just simply to early for snowfall south of that line, outside of the Appalachians.)
2) The storm stays as one, and quite simply ejects towards the Great Lakes, dragging a cold front across the U.S.
Effects: Cold front in the East, Snowstorm in the Upper Midwest.
3) The Storm stays as 1 whole storm, and stays in the southern jet of the jet stream, but instead of riding up the coast, ejects somewhere between the East Coast and the Great Lakes.
Effect: Heavy Rain for the Mid- Atlantic to the Northeast, and a snowstorm in the Great Lake Region.
Here is my early forecast.
The NAO is going negative. I will save what that is for another post. But basically all it does is allows storms to ride up the coast, and blocks them from going through the Heartland. When the NAO is postive, it is the opposite. However, the NAO going Negative isn't set in stone that it will happen, or when. This storm is still a week away, but here is my best guess.
The Storm will eject into two pieces. The first will go quick and fast toward the Great Lakes, Ontario Canada Region. There will be a cold front dragged ahead of this Low, and will bring rain and colder weather to the Eastern U.S. The Second low will lag behind in the Southern U.S. The Front will stall along the coast, and the low will ride up the coast along the stalled front. Snow will fall from the West Virginia Appy's all the way up the Northeast. The Major Cities, should be spared a major blow, but some snow is likely. It will rain south of the Mason Dixon Line. One thing I am worried about is a possible ice storm for the Souther Appalachians, with marginally cold air in place, it is a posibilty.
This will most likely change, so check back later. If the NAO goes and stays Negative, the pattern pattern in the East may be changing. I will post about that in a later post.
