Regional Weather Outlook 2-24-17

Corn Belt weather:

  • A strong low pressure area has been responsible for a lot of rain and snow so far and will be bringing more, with the heaviest snow accumulations today will be in northeast IA, southeast MN, WI, and across MI.
  • There won’t be much snow south of I-80, most of it falls to the north.
  • A cold front develops out of the low presssure circulation later this afternoon and sweeps through the eastern Belt, possibly bringing strong to severe weather later today, with gusty winds and small hail the biggest threats.
  • Rain totals could be .25-.75” in the eastern Corn Belt before all precipitation is done by tomorrow.
  • A long tail of wraparound moisture could bring some lake effect snow tomorrow morning to northern IN and southern MI.
  • Strong high pressure follows this in and bring some cold air back to the region, with temps near normal on Saturday, but strong south winds on the backside moderate temps quickly.
  • Next week will be a soggy one, starting with light moisture into the southern Corn Belt on Monday morning as scattered showers and a few rumbles of thunder show in MO, southern IL, western KY, and then expands into IL and IN.
  • Rain totals will be .25” or less, but this is a precursor to a stronger wave moving through Tuesday afternoon/evening-Wednesday bringing .5-1.5” over 50% of the Corn Belt, with most falling east of the MS River Valley.
  • An area of low pressure brings some snow to WI and upper MI but it’s not part of the bigger system bringing rain to the eastern Belt.
  • Strong high pressure moves in Thursday-Friday with temps back down to normal, more typical of February than April.
  • Looking at mostly light precipitation at the end of next week and into the weekend in the eastern Belt and Great Lakes, but snow/rain mix totals will be .03-.1” or less, and then it’s dry and sunny for the rest of the weekend.
  • A big low moves out of the northern plains late next Sunday afternoon, bringing several inches of snow to MN and WI with strong winds.
  • Behind that, most of the western US is clear, which means we settle in for several days of dry weather.
  • Temps over the next 10 days will be near normal.

 

Deep South weather:

  • A frontal boundary works through the Deep South late this afternoon-tomorrow, with the heaviest precipitation staying in the northern half of the region, including KY and TN.
  • Rain totals will be .25-.75” up north and farther south they’re looking at hit and miss action of .1-.2” there, with coverage in the region at 60%.
  • Strong high pressure parks over the Deep South by Sunday morning, knocking temps down a bit, at freezing or below down into northern AL, MS, and north GA.
  • The high moves off the coast and then moisture moves up the backside, with a system on Monday-Tuesday bringing .25-1” rains to 90% of the region, and there is a possibility of strong to severe weather in eastern AL, GA, and SC.
  • Another front wants to move through Wednesday afternoon-Friday, bringing heavy rains and a good chance to strong to severe thunderstorms, with totals of .5-2” and 75% coverage.
  • The biggest threat of severe weather looks like TN, AL, GA, and the Carolinas.
  • All of that moisture is off the coast on Thursday afternoon and high pressure is back in control and keeping things dry from late Thursday afternoon-Sunday.
  • A little moisture develops off the coast on Sunday night and it does look to push northward into Monday, keeping the door open for scattered showers over 60% of the Deep South, with thunderstorms possible over FL.

 

Great Plains weather:

  • Snow is still falling in NE, southeast SD, and northeast CO today, expecting another coating-2” in NE and northern KS, along with northeast CO before everything is done.
  • ND and most of SD is dry up north and things are also dry to the south in the plains, including TX, OK, and southern KS.
  • High pressure will then dominate the plains going through the weekend, bringing temps down dramatically from where they’ve been.
  • By Sunday, south winds up the backside will moderate temps a bit.
  • Next week, the plains will be a hit and miss deal as far as precipitation; for example, Sunday night-Monday will see scattered showers and thunderstorms in eastern OK, northeast TX, and possibly southeast KS, totaling .25-.5”, but the rest of the plains will see nothing, with the only exception being some light snow showers Tuesday afternoon in eastern NE and southeast SD.
  • Basically nothing then for Wednesday-Friday before another strong system tries to come together in the northern plains at the end of the week, diving across ND and northeast SD, bringing a coating-several inches quickly, but the rest of the plains from I-90 southward is completely dry.
  • Temps will be near normal as we won’t see the bottom drop out.
