For those of you who love winter, it may get underway very soon for the upper midwest, according to the latest GFS model. The potential system appears to originate from the Yukon territories and dive southeastward towards the US. However, I do not think it will be cold enough for snow south of I-94, but areas like Grand Forks, Winnipeg, and International Falls could have a very interesting end to summer. Now, this is two weeks out and a lot can happen, and consistency needs to be seen before any possible scenarios are looked at. This does fit the idea that was put here by Weather Advance and other meteorologists that September may be warmer than normal, however, we will probably begin to see a temperature crash as September comes to a close. Even if this does not happen, it is definitely a very ominous sign to be talking about a possibility of snow in September before summer has even ended, and is a sign that the el nino over the central pacific is maturing and will help to lead to a cold winter across areas mainly east of the rockies. Regardless, this is an indication that summer will be coming to an abrupt end as the natural seasonal changes begin to occur, and as that happens, unlike last year, where pressures were low over the US, the pressures will flip over North America, and the US is going to experience higher than normal pressures. The reason for that is the surrounding air masses over the atlantic and pacific will be warm, and that forces pressures to lower over those areas, and stuck in the middle, the US must see an appreciable pressure rise due to this, and as we all know, cold air in the winter is associated with higher pressures simply because cold air is dense and sinks, causing pressures to rise. Interesting times ahead.
