Monday: 5:30 PM
Some areas across the Delaware Valley received the first frost of the season early this morning.
Overnight and into Tuesday morning, I expect widespread heavy frost across the entire Delaware Valley, including all of DE and the coastal regions of NJ.
Areas of Interior Southern/Central NJ and the suburbs of SE PA, could see freeze warning criteria, as some of these locations will drop to between 28-32 degrees. The remainder of the Delaware Valley will see temps between 33-36, this mainly in urban and the immediate coastal areas of NJ and DE, but frost is likely there as well.
Tomorrow temperature rebound to the mid and upper 60's as the beginning of a milder period continues for much of the week. For Wednesday and Thursday expect highs in the Upper 60's to low 70's across the Del. Valley, we should remain dry both days.
I'll have more on Wednesday for the potential of another wet but this time a milder event, towards the end of the week and into the early weekend. Friday night and Saturday could be a washout, with 1.00" plus rainfall amounts.
