Regional Weather Outlook 2-8-17

Corn Belt weather:

  • Light snow is moving across the eastern Corn Belt today, with snow moving out of IA, across IL, and IN, leaving a coating-3” in spots.
  • It’s a fairly minor event along the leading edge of strong cold high pressure coming into the region.
  • High pressure will work across the Corn Belt for the following three days and as it moves east on Friday, strong winds shift back to the south and temps will rise dramatically.
  • The next weather system doesn’t move in until Sunday, with low pressure over IL in the morning, bringing snow to WI and northern MI, and rain in IN, lower MI, and parts of OH, but there is a dry slot through part of IL.
  • It turns into a much bigger rain even over the rest of Sunday, where OH could see moderate to heavy rains, but overall, it hits 40% of the Corn Belt.
  • Another strong high pressure dome moves in after that on Monday-Tuesday, centered a little farther south over the OH River valley.
  • There won’t be any serious weather systems moving through next week, and with the only serious precipitation sticking in the Deep South, Monday-Saturday could be dry.
  • There may be a clipper system moving out of Canada into the Great Lakes, which could affect WI, MI, and northeast OH from Thursday-Friday.
  • Temps will be fluctuating, warm then cooling off, then warm before another strong Canadian high moves in next week, so temps in the early forecast are normal to above and then normal to slightly below over the second half of the ten-day forecast.
  • We aren’t done with cold weather yet even though we really haven’t seen a long stretch of winterlike temps.

 

Deep South weather:

  • Thunderstorms are still moving across the eastern part of the region, including NC, SC, and GA.
  • Another batch of light rains will move through KY, TN, NC, and SC, through tomorrow.
  • Rain totals over the next 48 hours will be .5-1.25” with 70% coverage in the eastern half of the region.
  • A strong surface high then parks over the region on Thursday night-Friday, cooling temps briefly before strong south winds take temps back up well above normal by the weekend.
  • The next round of precipitation develops on Sunday night in AR, western TN, KY, and northern MS, with a line of showers along an old frontal boundary totaling .25-.75” with 75% coverage from the MS River westward and 30% coverage to the east.
  • A lot of moisture comes together in TX on Monday-Tuesday, moving into AR and LA before slowly moving across the rest of the region Tuesday-Thursday and leaving behind good rainfall amounts.
  • Colder high pressure moves in to dry things out for the rest of next week on Friday-Sunday, bringing cooler than normal temps.

 

Great Plains weather:

  • Snow is leaving NE and SD this morning and a mostly dry pattern is emerging through the balance of this week.
  • High pressure is in control from this afternoon-Friday, then strong south winds start up behind it and really warm the plains up quickly, with high temps pushing into the 40s.
  • A system begins to move through on Saturday with cold air pushing back into the northern plains and possibly mixed precipitation in SD, NE, southeast WY, and northeast CO, with moisture equivalent at 1/3” in those areas.
  • It’s short lived on Saturday night-early Sunday, and then high pressure pushes back in Sunday afternoon.
  • That high pressure will be in control for most of next week and keep things dry, with the exception being TX.
  • Moisture circulates in TX Monday-Tuesday, totaling .25-.75” with 60% coverage; the panhandle will likely miss out.
  • There aren’t any strong systems in the western US so things look very calm in the upcoming forecast and it may be closer to the end of the month before the next system develops.
