Regional Weather Outlook 1-24-17

Corn Belt weather:

  • A strong low pressure area will move out of the central plains and into the western Corn Belt later this afternoon, bringing snow into western IA and southern MN, moving across WI, northern IL, and into the Great Lakes region tonight-Thursday.
  • Snows will be heaviest across IA, southern MN, southern WI, and northern IL, where the totals could be 3-6” in spots, with rain mixing with snow along the southern edges of those areas.
  • The system moves northeast over the Great Lakes region and could bring some snow over northern IN and northwest OH Wednesday night-Thursday, but accumulations will be minor, maybe a coating up to 1” maximum.
  • Strong north winds on the backside of the low will draw down cooler air for a couple of days but it won’t be an arctic blast; those winds will stick around through the rest of this week and into the weekend.
  • High pressure will dominate from this weekend through next week; one strong surface high holds Sunday night-Monday before another moves through after that.
  • In between the two high pressure areas, a strong low pressure areas moves across Canada from Monday night-Wednesday, probably hitting the New England area more so than the Corn Belt but will likely increase winds over the Belt by the middle of next week.
  • After the next 24-48 hours, we are shifting into a drier forecast period.


Deep South weather:

  • A cool front stretching from low pressure in the Corn Belt may try to work through the Deep South, triggering a few widely scattered showers starting tomorrow night-Thursday, with no more than a few hundredths to .25” maximum with 60% coverage.
  • Behind it, high pressure takes control going into the weekend.
  • Next week, moisture will stay just off the Gulf coast, possibly hitting the FL peninsula, but that’s it because high pressure sits of the central part of the region Monday-Wednesday.
  • Some rain and thunderstorm action is possible in south TX at midweek but it doesn’t look to rotate up into the region, so the region is in for an 8-9 day dry stretch after the front moves through tomorrow-Thursday.
  • Temps will be normal to slightly above.
  • Most of the action showing up in the extended forecast seems to stay farther north or just offshore to the south in the Gulf of Mexico.


Great Plains weather:

  • Snow is moving across the central plains in the short term today-tomorrow, with the hardest hit areas including NE, where they could see 3-6” there; a coating to 1” possible in northeast CO; some snow could also hit northwest KS; 2-5” are possible in southern SD.
  • Snow showers may linger in NE and southeast SD tomorrow as the system moves to the northeast, but the rest of the plains clears out and is on the way to a nice pattern for the rest of the week.
  • Strong northwest winds will bring down temps a bit on Thursday-Friday but nothing major.
  • High pressure is then in play through the weekend and all of next week and there isn’t any significant precipiation through the end of this week and all of next across the plains.
  • Not seeing a lot in the extended forecast window either; maybe some precipitation moving across the northern plains around February 5-6, with light snows from the Canadian border down through NE.
  • A better chance of more significant precipitation moves in February 8-9, bringing significant snow or a rain/snow mix into SD, NE, and KS.
