WIND CHILL ALERTS FOR MUCH OF THE AREA THROUGH THIS AFTERNOON

WIND CHILL WARNING FOR LUZERNE AND PIKE COUNTIES THROUGH MONDAY EVENING

Good afternoon! And welcome to the coldest part of the week. It's an odd way to honor Dr. Martin Luther King Jr., but at least it will be bright! Mother Nature will throw us a couple of bones ahead of a bone-chilling forecast in addition to that sunshine. The same thing that will make temperatures feel much colder all day long, also got rid of this weekend's standing water. We're talking about those whipping winds that started howling Sunday afternoon. So, drivers only encountered some patches of black ice on secondary roads and in untouched parking lots Monday morning. We're thankful for that.

Let's talk about your weekend for a moment. Rising temperatures Saturday night changed snow and ice to plain rain across much of the area Saturday night, with mainly rain showers tapering off through midday Sunday. The exception was in the Poconos and northwestern New Jersey where ice had some commitment issues--flirting with rain, but not quite changing over to rain completely. Coincidentally, that's where high winds will continue to put power-lines in jeopardy. Tree branches coated in ice snapped off and fell onto power-lines in spots. Not a good situation given the Arctic chill that invaded our area. Our departing storm dragged Arctic air down into the mid-Atlantic and northeast Sunday afternoon leading to crashing temperatures. Early highs in the upper 30s dropped into the middle 20s by the afternoon, and the single digits overnight. So, for anyone out and about enjoying that total lunar eclipse, it was downright frigid. It's the same weather story for Monday as polar high pressure continues to interact with this weekend's departing storm. We'll turn the page come Tuesday as we lose those winds. And by Wednesday and Thursday, we'll start a new weather chapter completely as another rain-maker moves in from the west.

For now, it will be mostly dry with an Arctic chill married to whipping winds. Temperatures will feel as cold as -10 to -20 degrees for Martin Luther King Jr. Day, which is why the National Weather Service hoists wind chill alerts for the entire area through at least the early afternoon. It'll be even colder for our friends in the Poconos and northwestern New Jersey; perhaps as cold as -30 as winds gust slightly higher. A consequential snow shower or flurry can't be ruled out there for that reason, while skies are sun-splashed elsewhere. Don't be fooled by sunshine, of course. Air will be dangerously chilly despite the sunshine for anyone working or playing outdoors. Frostbite can form in just thirty minutes! Please wear plenty of layers until those 30-40 mile an hour wind gusts diminish overnight Monday. With that said, there is something pretty spectacular happening in the night sky Monday night. Admittedly, it's a tough sell given the forecast, but we know some of you will go outside anyways... The International Space Station will fly by from the southwest to the south at a maximum height of 41 degrees from 6:54 to 6:56 Monday night. Skies will be starry then. Forecasting a cuddle alert otherwise Monday night with temperatures tumbling into the single digits, still feeling sub-zero early on.

While you're cuddling, Venus and Jupiter will be tucked close together too. Jupiter will appear 2.5 degrees below Venus in the eastern sky pre-dawn on Tuesday. Check it out! The rest of Tuesday is still chilly with high temperatures stuck in the freezer. We lose the wind, though, so temperatures are 'what you see is what you get' temperatures. There will be plenty of sunshine for most of the day before some clouds build in late and by Tuesday night ahead of our next system marching our direction from the Great Lakes. There's some timing issues with this one... We think most of our precipitation comes Wednesday afternoon when temperatures lift out of the freezer and into the lower 40s. However, should precipitation start early than that, some freezing rain will be possible. That's in our forecast for now, just in case. A little bit of ice can go a long way! Otherwise, plan on increasing clouds Wednesday with rain developing in the afternoon and as late as the evening southeast of the Lehigh Valley. Colder air filtering in Thursday could change rain to snow briefly before precipitation tapers off. 

Warm wishes this MLK Day! Especially for those working outside. Be safe!
