The preeminent ECMWF weather model is forecasting a record-breaking ridge of high pressure in the Northeast U.S. later next week đȘ
đĄÂ Called a "600 decameter ridge", these monstrous highs are a relatively rare summertime visitor to the central and western U.S. but have not been recorded over the Northeast U.S. â yet.
Because air expands and rises as it warms, this ridge pumps higher up into the atmosphere. The height of the ridge is related to the temperature of the atmosphere. In this case, the height of the 500 hPa pressure level is forecast to reach 6 kilometers or 3.7 miles.
â«Â Described another way, the ridge is forecast to be about as tall as 16 Empire State Buildings stacked on top of one another!
It remains to be seen just how hot it gets under this noteworthy ridge and if it indeed reaches 600 decameters, but 100+ degree temperatures appear possible for parts of the Northeast and Mid-Atlantic later next week...
