Everybody ready for the weather 'F-word?' Some pretty major talk of frost and freeze later this week up north, and temps will really sink -- down to the 40s -- as far south as St. Louis by Friday. So, will this trump any of today's info from USDA?

If it does get that cold long enough and it sounds like it could be for multple nites, than you could take off some bean bushels on those fields that are still pretty dark green. Top 4-6 inches on the beans could have bb's in the pods. As for corn, probably less noticeable. Ears are maturing and probably won't get cold enough to freeze that far down...MikeM

I just looked at the latest weather forecast for my area of SESD on Wednesday night and the local TV station is saying 37, weather.com is saying 34 and National Weather Service is saying 33. A frost will hurt the beans more than the corn at this stage of the game, although the later planted corn could still lose some bushels if it gets cold enough. There are a lot of grass grean bean fields that will take a beating around here with a frost on Wed. night. Some fields that were planted two weeks later than normal are now facing a frost about 10 days to 2 weeks earlier than normal. Not good if it happens.

Once it is forecast for that kind of a low, it will probably get colder and last longer. This is pretty much par for our course this year. the rain we needed and got a couple of weeks ago that helped out the later beans just ended up killing off the top end of those anyway. You have one variety that is safe for sure, John. Got the cutterbar ready on the beanhead?...MikeM

A lot depends on where the HIGH sets up and winds go calm. The EURO this morning drops that high from central N Dak on 0z Thursday to Milwaukee, WI on 0z Friday. This is a change from the previous run that dropped the high down into SE SD and then slid it east to Detroit. I would say N MN sees a hard freeze Weds nite, along with areas of central WI Thurs nite. Other areas will most likely have a good shot at frost, depending on winds. I'm in SW Wisconsin along the Mississippi and even here I'm guessing around 36F with patchy frost.

In my part of e-central S.D. most fields tthat are group 1.2 and lower and were planted in a reasonable time frame are
turning color. Later varieties are mostly still quite green. It all depends as always how low and how long. I will include our
latest forecast below.
THEN ATTENTION TURNS TOWARD WEDNESDAY NIGHT.
SFC HIGH MOVES RIGHT OVER THE NORTHEAST CWA. TEMPS SHOULD
CERTAINLY FALL TO FREEZING OR EVEN COLDER ACROSS MOST OF THE
REGION...THUS THE FREEZE WATCH WILL BE UPGRADED TO A WARNING
