Loop below shows dew points into the final week of the month. Yellow/orange is more humid, even tropical air. Blueish color is the dry comfy stuff, like today. After Tuesday, GFS has literally no dry air through the 27th of the month. Similar Sept pattern to a few years ago.😭 pic.twitter.com/NIyhEytl8f
