10 Day AG-Weather Outlook
Issued: 01.31.16
Forecast period: 02.01.16 – 02.10.16
Focal Items:
- Plains blizzard Days 1-3
- Severe threat from the Mid South to the Ohio Valley Tuesday
- Impactful winter event developing late in the period
Summary: The forecast period will begin with strong ridging across the eastern half of the CONUS, while a significant trough digs across the west. That trough will lift northeast through the middle of the upcoming work week before re-amplifying over the upcoming weekend into early week 2 across the Plains and Ohio Valley region.
Sensible Impacts: A significant storm system will move off the Rockies and into the Plains Monday. The surface low will track northeast from SE CO Monday night into SW MI Tuesday night. To the north and northwest of the surface low, heavy snow and blizzard conditions will impact areas from CO, KS, NE, IA, MN, and WI. South and southeast of the surface low track, strong to severe thunderstorms will rumble through the lower MS Valley, TN Valley, and Ohio Valley Monday night into Tuesday night. All modes of severe weather will be possible, including tornadoes.
We’ll need to keep a close eye on the potential of a clipper system diving SE across the N. Plains and upper Ohio Valley over the upcoming weekend, but the bigger event appears to be a developing winter storm threat centered on the end of the period (2/8-2/10 time period). There are, obviously, a lot of details to sort through, but an impactful winter event is very possible across the Ohio Valley towards the end of the forecast period.
Temperature Anomalies: The period will open much warmer than normal, but transition cold, and eventually colder than normal by the end of the period across the forecast region.

Precipitation: A stripe of heavy snows (10″-15″) will fall from CO, NE, IA, southern MN, and WI with the initial early week storm. .5″-1.5″ of rain will fall across the Southeast, TN, and OH Valley regions (locally heavier totals where strong storm train). Overall, quieter times return mid and late week for the forecast region before the next potential strong storm develops late in the period.
