This afternoon’s blowtorch has many from the Plains to Mid-Atlantic scratching their heads as exceptionally warm temperatures rocketing to mid-September levels and 20-30°F above normal for Dec 3. Today’s astonishing all-time record warmth is a byproduct of the weeklong wild pattern which has hammered California and the West. As much as 23.4 inches of rain feel at Brandy Creek, […]
