Temperatures that are starting off mostly in the middle and upper 30s in some cases will either hold nearly steady, or slowly fall later Friday. Then at night, under a mostly clear sky, it will be quite chilly with lows in the 20s.
Saturday and Sunday, temperatures are still expected to do an “about face” across much of the Northeast and in the Mid Atlantic states as the wind shifts to the southwest. There should be a surge of air mild enough to push most temperatures into the upper 40s to around 50 Saturday, and mostly the upper 40s around here on Sunday. But also Sunday, the winds should start to pick up quite a bit in the afternoon out ahead of the next, approaching arctic cold front.
This should drag some much colder air into the area on Sunday night, and most temperatures on Monday will be no higher than the mid 30s in the afternoon.
As a trough of low pressure in the upper atmosphere does some additional digging next week, we will be stepping down into an even COLDER weather pattern, with most temperatures no higher than 30 on Tuesday, and the 20s on both Wednesday and Thursday.
