Big system, bigger drop
A huge temperature drop will follow our departing storm system. For Thursday afternoon, after having temps reach their pinnacle in the mid 60s, they’ll plummet into early Friday morning into the low 20s. In about a 12 hour stretch, I’m looking at around a 40-45° temperature drop in that time. Looking into the record book, the largest temp drop on record during the Fall months occurred in Oct. 2018 at 47°.
Temps ultimately drop back into the upper 20s for highs and 10s for lows. At times the wind chills will drift down into the single digits Friday and Saturday. This is the new norm. We’ll stay down at chilly levels for a while.
