The pattern has flipped around across the hemisphere with mid-latitude amplification flattening out with the NAO/AO going positive but as a result, rather than dealing with unseasonable cold and snow, the storm train off the Pacific has cranked into high gear for the Pacific Northwest following a record dry spell. If you live in the […]
The Pacific jet has significantly strenghened over the past few days and over the next 7 days, we will see one storm after the other slam the Pacific Northwest but this unsettled weather with wind, rain, surf and mountain snows, extends down the coast. Expect soaking rains down through San Francisco and likely even Los Angeles. As […]
Any storm which threatens the Northeast is a worry following Sandy and the damage and exposure brought to beaches, as well as the weakness to trees, power and property. For many days now, models have shown a Pacific disturbance crossing the country which will deepen a trough already established over the East. This feature will draw energy in as it moves offshore and is set to develop […]
As forecasted here from well over a week ago, as the western trough deepened and slid east, so the ridge pumped up the East Coast. The combination of sunshine and enough southwest wind forced temperatures to warm to levels more typical of September and not mid-November. This of course is in stark contrast to the […]
We live in very interesting times. With the NAO/AO now positive, we’re seeing the atmosphere do what I’ve been hoping for and that is the building of cold over the source region during November. Given the negative trend in the NAO ensembles and the forecast of a return to negative later this month, this reload at a time […]
The arctic air which entered Montana first will slide across the Dakotas today and Minnesota, Wisconsin tomorrow. The arctic air is moderating as it pushes east and if you live in the East, this never reaches you! By Tuesday, the amplification starts to flatten across the country with the flow turning zonal. The door to the arctic […]
There is a very large temperature spread currently between Montana and the Mid-Mississippi Valley. While temperatures are running 20-30 below normal over the Northern Rockies, it’s 10-20 above normal further east. This sharp divide is courtesy of a vigorous storm system and it’s potent cold front. Along the front, warm air is being driven northeast […]
As stated in my previous post, the stage is being set for an increasingly large temperature contrast this weekend both locally, ahead and behind a sharpening cold front and across the country. While snows and potentially blizzard conditions continue for some, warmth, gusty southwest winds and strong to severe thunderstorms will be the weather talk […]
There is a wild pattern setting up across the United States with a major trough developing over the Rockies while ridging is pumping unusually warm air north through the Plains today, Ohio Valley Saturday and East Sunday. The big player is a major storm system intensifying over the Northern Rockies heading NE, the backside of the circulation […]
It has been an unbelievable past 10 days for the Northeast and especially New Jersey and Greater New York City where the hardest impacts from Sandy were felt and will continue to be felt for a long time to come. So, it was Sandy last week and now it’s Winter Storm ‘Athena’. A Nor’easter which began to get […]
