Premium: Warming trend in the East will be short lived

/by

Weather news this week has been centered around the presence of a large ridge, building into the Central United States. This ridge will reach eastward to the Ohio Valley, with tremendously warm temperatures surging from the desert southwest into the heart of the country. In the East, however — especially the Northeast — this warm air will be short lived. An active pattern throughout the Northern jet stream will keep the upper air pattern very active, and the amplification of the pattern will allow colder air to surge into Southeast Canada and the Northeast.

Much of this will be centered around a cold front, which will move through the Northeast US on Thursday afternoon and evening. Temperatures will warm up throughout the East on Wednesday and Thursday. Thereafter, on Thursday afternoon and evening, an  impressively strong system in the mid and upper levels of the atmosphere will drop southward into Southeast Canada and eventually the Northeast, interacting with moisture and providing sufficient lift for heavy rain.

Premium: November Outlook and pattern evolution

Changes in the stratosphere have been well documented and explained over the past several days and, despite the fanfare, have not yet had their dramatic impact on the weather pattern across the Continental United States. But in due time, they will, and it will likely begin — ironically — at the very start of the month of November. A much more amplified pattern in the higher latitudes will kick off changes in the Pacific Ocean, starting with a much more amplified Pacific Jet.

This Pacific Jet stream will flood the United States with warm, maritime air as a large vortex forms in the Gulf of Alaska. This is an important development for several reasons moving forward, but in the interest of November alone, its short term significance will be verified by a surge of much above normal temperatures into the Central and eventually Eastern United States.
