Temperatures were in the 70s and 80s yesterday over Montana and during the overnight hours, the first of two strong cold fronts swept through dropping temperatures sharply and forcing snow to break out. These snows were falling earlier in the day yesterday over British Columbia and Alberta as the cold air rished south on the […]
The models continue to throw the BLUE paint bomb on a large swath of the Lower 48 with the latest 6-10 day off the Climate Prediction Centre showing a particularly cold look. This way this is shaping up with a powerful ridge pumping all the way to Alaska and the fact the Arctic Oscillation is […]
Often during October, when a major cold shot drops into the heart of the Lower 48, a heatwave is going on over California. This time around will be no exception. The reason? a highly amplified pattern with a major dip in the jet which has arctic air forced south will have warm air lifting north […]
Tonight’s run of the ECMWF now has next week’s very cold air pushing south of the US-Canada border and this could mean an early snowstorm as well as 15-30 below normal temperatures anywhere from Montana to the interior Northeast. While the arctic hound comes acalling next week down the spine of the continent, often during October cold blasts, a strong ridge […]
Thought I would touch on a few points regarding the pattern into NEXT WEEK for both the United States and Canada. Noticed me talking about Typhoon Jelawat? Well this system is going to recurve but unfortunately it won’t miss land. The southern Japanese island of Okinawa looks to be yet again a target and powerful Typhoon […]
Yet another monster low has formed and can bee seen spinning just south of Alaska, set to bring yet another round of powerful, potentially damaging winds onshore over South-Central Alaska. The GFS shows pressure falling all the way into the mid-950s in mb, incredible. I wonder if this depth is record challenging for September? The centre of this monster is expected to strike […]
The pattern is now undergoing major changes with the return of a more positive NAO/AO with modeling showing the flattening out of the jet which will push the cold air back up into Canada and allow maritime air to flood the Lower 48 for the most part. This will however send in storms as we progress […]
Computer models show now-strong Hurricane Miriam taking a path which brings it ashore along the central Baja coast late this week. What’s significant is not so much the storm hitting this part of the world but the potential rainfall it could bring to the Northwest of Mexico/Southwest US as well as the Southern Plains. This […]
We’re now entering deeper into autumn with winter fast approaching. October is pushing ever closer and this transitionary month can be a critical telltale month as to what we may expect later down the road. It was Joe Bastardi a few years back who said to me that often (not always), where the wettest weather and trough sets up […]
A cold upper low passing over the Great Lakes Friday night brought the first snows to parts of northern Minnesota and Wisconsin with several reports of a trace to as much as 1-2 inches which of course melted quickly due to warm ground. Following a cool day Saturday, clear skies, light winds became established thanks to a lobe of colder air coming down […]
