IMPACT: A wintry mix moves in today, then transitioning to rain across south-central Pennsylvania

The next storm system is knocking on our doorstep. At higher elevations we will see a mix of snow. A brief snow/rain mix for the rest of the area before transitioning to all rain. Stay tuned for the latest.

Overnight skies were mostly clear to partly cloudy, causing temperatures to drop to the low to mid 20s this morning. HIGH PRESSURE, VERY STRONG HIGH PRESSURE AREA OVER THE NORTHEAST PROVIDING THAT COLDER AND DRYER AIR THAT IS PRESENT. Now you’ll notice the storm system moving through the Ohio Valley. THIS MOISTURE WILL RAISE EASTWARD. However, it will take a while for the atmosphere to become moistened and for this precipitation to fall. It looks like it will last until the early afternoon hours. SOMEWHAT LATER. FOR OUR EASTERN COUNTRIES. Everything is quiet at the moment. We will have partly cloudy to mostly cloudy skies. The clouds are getting thicker until this morning. TEMPERATURE 22 DEGREES. Luckily the winds are calm so the felt temperature is still quite cold, but it is 22°C. Here’s a look at your News Eight storm team’s forecast through 8 a.m. We have mostly cloudy skies and 26 degrees. It’s pretty frosty out there this afternoon. A snow-rain mix will develop starting in the west and moving east. TEMPERATURES IN THE MID 30S. IT MAY RAIN TONIGHT. We could still see a snow/rain mix north and west of I-81. TEMPERATURES ABOUT 34 DEGREES. RAIN PROBABLY TONIGHT. A LITTLE NORTH A MIXTURE IS STAYING AGAIN, BUT MOST OF THE AREA WILL HAVE THIS RAIN. THERE MAY BE SOME Isolated, Slippery Spots WHERE THIS MIXTURE WILL CONTINUE AND WHERE THERE WILL BE SOME ACCUMULATIONS. Temperatures will remain steady in the low to mid 30s for the remainder of the night. TOMORROW THE RAIN WILL CONTINUE IN OUR EASTERN COUNTRIES BY 8 OR 9:00 A.M. IN THE REST OF THE AREAS. Fog and drizzle are possible. It looks cloudy most of the day and rain will return in the late afternoon and early evening. TEMPERATURES IN THE LOW TO MID 40S FOR TOMORROW. NOW WE HAVE 27 IN CARLISLE, 24 IN LEBANON AND HARRISBURG, 25 IN YORK. And here’s a look at this storm system. Let me set aside time for you while we look at Predictor. So I would say this particular model is available much quicker than some of the others. BUT THIS IS 11:30 AM. THERE COULD BE SOME LIGHT PRAYER, BUT ALSO: WE HAVE VERY DRY AIR SO IT WILL TAKE A TIME FOR THIS HUMIDITY TO REALLY FILL OUT ACROSS THE WHOLE REGION. YOU CAN SEE WHERE MOST OF THE SUSQUEHANNA VALLEY WILL SEE RAIN AND MOST SNOW AND SNOW MIX WILL BE NORTH AND WEST OF I-81. But don’t be surprised if you see a few wet flakes at first before it turns into plain rain. It continues to rain overnight, but by 7:00 a.m. you can see that much of it is moving east, leaving behind cloudy skies. The next chance of rain will be during the late daylight hours on Monday and then Tuesday. We dry out. Looks like a pretty good day and it’s going to be a mild day. The mildest of the ten day forecast. So if we look at the rain-snow map for today, you can see that much of the area will be plain rain. Now there could initially be a mix of rain and snow, which quickly turns into rain. But in the north and west I expect 1 to 2 inches of snow. So on the ridges and primarily north and northwest of I-81 where we could see the best chance for accumulations. The ten-day forecast shows temperatures in the 40s for tomorrow. WE WILL BE IN THE 50S ON TUESDAY, BUT ANOTHER STRONG SYSTEM BRINGS A CHANCE OF RAIN AGAIN WEDNESDAY AFTERNOON. It looks like most of this shower activity will happen here early Thursday morning. Temperatures will trend colder and Thursday will be breezy and breezy. We have 30 seconds to go back on Friday and look at the temperatures as we head into the second half of the weekend. Another system is bringing in an even colder shot of Arctic air. Overnight lows will be in the teens and highs will be in the teens
