Upcoming Pattern Could Lead To Long Term Cool Temperatures

          In the next several days, temperatures will remain about average, but as we head into next week, a new pattern is likely to set up that could but stubborn and last potentially quite a while. By the early part of next week, troughs will begin flowing down from Eastern Canada and effect the region. This will bring below normal temperatures to the Great Lakes and Northeastern United States for a quite a while because they will just continue to dip don into the area. There could be a day or two between jet stream/trough where we go back to average temperatures, but you won't have to wait long for another trough to find it's way down here.

          This is because of a few reasons, one if the NAO and AO are dropping negative, causing us to receive cooler temperatures and also because the high pressure system in the west in very persistent, and will likely not expand to grant us warm conditions like it recently did. Temperatures will likely be held to the 50's north and in the mountains to middle 60's in the south and lower elevations regions as highs. At night, temperatures could get into the 30's in the north and the 40's south, which is much below average from where we should be. Here is a map showing next week's weather pattern that could likely stick around for an extended period of time.
