Front Packs Punch

Reality is checking back in after two days of September-like warmth in the Delaware Valley. After highs of 68 and 71, respectively over the past two days, today's high of 63 (likely high) occurred at 1 AM.  We're now in the 40's and we won't get anywhere back near 63 by day's end...and just as likely, by week's end.

The past 24 hours has seen a rather marked cooldown across the Eastern US as the fleeting warmth of last weekend's and yesterday's warm surge is replaced by the return of chill.   Temperatures between 7 AM yesterday and 7 AM today are anywhere from 30 to 35 degrees cooler as colder air marches east in the wake of the cold front.

Compared to normal, those temperatures are not that terribly cold.  Most locations in Ohio and Appalachia are in the upper 20's and lower 30's -- nothing atypical for mid November.  The core of chill this morning is in the Upper Midwest and Western Great Lakes.  Lows this morning in the Minneapolis area were in the teens for the first time this cold season...over ten degrees below average for Minneapolis and over fifteen degrees below average in some parts of Iowa, Illinois, and down into Deep South.  The core of cold in this upcoming pattern will not reside over us but will shove into Canada over the coming days.  While crisp at night, high temperatures each afternoon will be close to average (but a few degrees shy).  Not a cold pattern on the levels of last week by any stretch but a reminder that 71 on Monday is not coming back for a while.
