Corn Belt weather:
- Mostly dry over the corn belt today, as the region finds itself inbetween systems.
- Another round of moisture is developing in the mid to lower mississippi valley tonight and will lift northeast tomorrow. The circulation strengthens tomorrow afternoon-night as moisture works through up the MS River valley into the Ohion Valley
- tomorrow night through Friday, the low moves across IN, bringing rain to the eastern Corn Belt, east of the MS River valley Thursday night-Friday night, with rain totals of .25-.75” with 75% coverage east of the MS River and nothing to the west.
- Another low kicks out of the central plains on Saturday with light rain and snow over the Upper Midwest, including MN, northern IA, and WI, totaling .3” or less, but a second low comes out of the plains and follows the exact same track from KS into MO on Sunday.
- Moisture moves through MO and southern IA before tracking east and becoming more powerful, affecting the eastern part of the country, bring .25-1.5” of rain over the entire eastern US.
- Heavier rains fall Sunday night-Monday in southwest IN, western KY, and southern IL, totaling 1-2” of rain with very strong winds.
- Combined from Sunday-Tuesday, rains amounts in the Corn Belt should be .5-1.5” and coverage will be 75%.
- The active pattern will keep going with another system behind it, coming out of the plains on Wednesday, into IA, and MN with .25-.75” rains and 75% coverage, tracking east into the Great Lakes on Wednesday night-Thursday with the same kind of totals with 60% coverage.
- That last system does begin to draw down some colder air by the end of next week, meaning the next system in the extended forecast will be snow on January 29.
- Temps will be normal to above normal over the next 7-10 days, but we’ll still pay for it with more cold air through the rest of the winter season.
Deep South weather:
- A line of showers and thunderstorms exits the Deep South We could still see some rains of .25-.5” as the action leaves the southeast.
- Much stronger action develops later this week with a significant line of thunderstorms developing in the western third of the Deep South through Friday.
- Heavy rains and severe weather roll through MS, AL, and into western TN Friday into early Saturday before marching across the rest of the region.
- Combined from tomorrow-Friday afternoon, rain totals will be .5-2” or more with 85% coverage, with the heaviest rain totals of 1-2.5” out in the western part of the region, and the lower totals out east in GA and NC/SC.
- The rains continue Saturday-Sunday before turning into a massive circulation Sunday night-early Tuesday over the entire region, so totals from Saturday-Tuesday will be 1-2.5” rains over 90% of the Deep South.
- A system late next week up north swings a cool front through the Deep South with nothing more than sprinkles and then high pressure finally follows that in Friday-Saturday with some drier air.
- Temps will be normal to above as south flow off the coast fuels the moisture but it also brings warm temps.
Great Plains weather:
- Moisture starts to develop over TX today totaling .25-.5” but it doesn’t get farther north, so the rest of the plains look good through Wednsday.
- The plains stay dry Thursday-Friday before a little light moisture moves out of the Rockies on Friday-Saturday, bringing mostly sprinkles to eastern SD and eastern NE.
- Moisture will develop in the Four Corners area of the desert southwest, but won’t kick out right away, waiting until Saturday night-Sunday to move into OK and KS with totals of .25” or less, but there is good circulation so coverage in those areas will be 60% before it moves east and gets bigger.
- The next system moves into the plains Tuesday night-Wednesday as low pressure moves into NE and KS with strong winds of 20-40 mph and higher, with the precipitation developing on the northwest side of the low.
- This will be in colder air, so it raises the possiblity of blizzard conditions in NE, northeast CO, southern SD, and northwest KS, but there is still plenty of time for this to change.
- As it moves east into the Corn Belt, high pressure follows it in and drags colder air into the region, but not necessarily an arctic push; it does take the freezing line down into OK and central TX next Thursday.
- The pattern may clear out after that as there isn’t anything dramatic showing up in the western part of the country after that.
- Temps in the plains are mostly normal to a bit above before the cold air takes it back down to near normal next week but likely not a lot below normal.
