Corn Belt weather:
- A storm complex centered in the eastern US is dragging moisture with it through the eastern Corn Belt today, including IN and OH, plus parts of eastern MI.
- A second wave of moisture comes through later today/this evening, just ahead of another blast of arctic air.
- Most of the second wave will be liquid moisture in IN, lower MI, OH, and down into KY.
- Snowfall is moving through MN and WI this morning before lifting northeast into parts of Ontario.
- Very strong north winds will wrap around the backside of the low tonight-Wednesday, setting up lake effect snow over MI, northern WI, IN, and OH.
- These lake effect zones could see significant accumulation, but the rest of the Corn Belt won’t see that kind of precipitation.
- High pressure then slides across the central Corn Belt, but it’s a “dirty high,” in that it will have some light snowfall with it that’ll work its way through 60% of the Corn Belt, totaling a coating to 2” possible.
- Most of that will fall in IL, IN, and OH, plus they’ll see some in MO and southern IA on Thursday morning.
- That snow moves east quickly and high pressure dominates through the rest of the week/weekend, Friday-Sunday.
- The arctic air and 0 degree temp line sneaks down to I-80.
- The backside of the high this weekend will see south windflow that will moderate temps Monday-Tuesday, but that’ll end fairly quickly as another strong storm complex works through the Upper Midwest on Tuesday afternoon-Wednesday.
- This brings snow to MN and WI, but they’ll just see winds further to the south.
- Wednesday night-Thursday will see a better precipitation chance right along the I-70 corridor, including MO, IL, and IN, with rain totals of .25-.75” and 75-80% coverage in those areas.
- The area could be in line for snow in the extended forecast in the western Corn Belt and rain in the east, January 14-15, if it can hold together as it moves closer.
Deep South weather:
- Things calm down a bit in the region after rains falling today move out by this evening.
- Thunderstorms start the day in NC, SC, eastern TN, and GA, with additional moisture at .25-.5” only.
- Dry tomorrow-Friday as snows in the OH River valley don’t appear to drop south at the end of the week.
- Temps push down close to freezing in MS and AL by the end of the week.
- Another storm complex moves through the coastal areas Friday night-Saturday, with coverage at 60-70% and totals of .25-.75” likely.
- The next system to move through the Deep South doesn’t come together until later next week as a system in the OH River valley doesn’t sag south, but there will be a cold front developing out of it and sweep through western and northern parts of the region Thursday afternoon.
- Rain totals will be .25” to a third, with 40-50% coverage in the region, with coastal areas likely more impacted by high pressure over the Gulf.
- The extended forecast isn’t showing anything that promises large amounts of rain later in the window, but there will be moisture just off the coast that will throw waves of moisture inland occasionally.
Great Plains weather:
- The plains look relatively quiet over the next 7-10 days after dealing with some lingering snowfall in the northern plains and Upper Midwest today and winds will subside by sunset tonight.
- The rest of the plains will see minor snows this week, with the best chance to come late Wednesday-Thursday as moisture kicks out of the central Rockies into the central plains.
- Snow totals may be 4” in eastern CO, but NE, KS, OK, and TX panhandle only see 1-2” of snow and no significant winds with it.
- High pressure sits over the plains from Saturday-Tuesday before snow comes back to the northern plains on Tuesday afternoon, including eastern ND and northern MN.
- Strong high pressure moves in later next week and keeps all areas basically dry, but a light coating is possible in NE and ND Wednesday night-Thursday, but that’s it.
- A system coming together out west on January 12-13 means the plains could be in line for another strong winter storm on January 14-15.
- Brutal cold temps will be the story this week in the northern plains through the first half of this week and freezing or below temps all the way down into TX.
- The cold does let up later this week as south winds kick up behind the high pressure dome, with next week looking seasonal as there aren’t strong systems moving through that can draw down the colder air.
