United States of America
It may be hot now over the heart of North America with 100s showing up over parts of Saskatchewan and Manitoba this week and to a lesser extent next week but there are strong indications of a significant hemispheric pattern change coming up in the next few weeks. September is sure to start off warm […]
At the moment, the sprawling upper high centred over the Plains is the dominant feature to the US pattern this week but there are noteworthy features causing headaches surrounding this wheel of heat. We have what was once Tropical Storm Fernand pushing copious amounts of moisture into the mountains of east-central Mexico which will cause flash flooding while […]
There are three noteworthy aspects to discuss across the Lower 48 not only today but through the next few. Taking centre stage will be the hot dome that will force temperatures this afternoon as well as Monday and Tuesday afternoon up towards or above 100 in several Upper Midwest locales including Minneapolis and Des Moines. […]
While a lot of focus shifts towards the building heat over the Plains in coming days, we also want to watch carefully the tropics and not one but two features may present big rains and an increased flood potential. While the upper pattern has changed in recent days which is helping ease the prolific Southeast rains […]
Think it’s hot now over the Dakotas into Minnesota, well it might be given the cool summer that it’s been but the secondary surge of heat which follows beginning Monday will comfortably beat what we have now. A low tracking along the US-Canada border will temporarily break the heat as it drops a trough down […]
After what has been a cool summer across the Northern Plains, the heat over the next 7-10 days will be centred over the Dakotas. Even today, highs are around the 100 degree mark over central North Dakota. Thanks t0 a system tracking along the International border, the heat pulls back Thursday and the cooling kicks in right across […]
As we continue progressing through August the pattern is shifting from mid summer into late summer and with the MJO pulse not only becoming more favourable for tropical development in the Atlantic, it’s also shifting the temperature profile across the US. We’re seeing it heat up considerably across the Northern Tier after a long spell of September-like cool with upper 90s […]
It’s been a cool summer from North Dakota to Florida and for Eastern areas, August has been downright chilly with temperatures averaging 4-8 degrees below normal. This comes on the heels of a cold and very snowy back end to winter and spring season. The NAO from the end of July turned negative and this along with saturated […]
We have a rather unusual upper level pattern currently over the Lower 48 and it is a fairly extreme one with a strong upper ridge pumping record heat north over the West while high pressure building down the East Coast has produced record cool days as far south as Atlanta where temperatures didn’t get out […]
