-3 tonight.

Plus 2 @ 4:30. Bit of dew on the vehicles, 89% RH. My beaten canola field receives a stay of execution but recovery will be slow and painful.

Dropping another degree or so into the Manitoba region (now all the way to practically Winnipeg) and south right to the US border. Appears centered around Yorkton and to south east in a significant area at least size of some "provinces"

Light frost on vehicles, even where weather stations are showing hovering just above the freezing mark. "Still" winds and usually coldest just as day breaks

Went from -1.1 at 5 am to -4.6 at 6 am! What the hell!

[furrowtickler]

That's what we seen here yesterday some areas dropped from -1 to -3 to -5 around 5:30 , just after sun rise . Seen it before , can be frustrating , but there was a steady -8 reported in the Glenbush to Mayfair area yesterday morning - not much crop checking to be done there now

[HappyFarmer]

Do I bother till wait till monday? It's a shame. I haven't had canola come up so nice in a while.

[furrowtickler]

Yes , I would wait. how much stubble where your canola is ?
Some canola fields here not touched much some fields are fried.
But I would also line up seed asap just in case and or matador to keep bug pressure off if you leave it.

Set an indoor/outdoor thermometer outside last night on a upside down 5 gal pail. It was an open area on the lawn. Reads -2.1 on the indoor and -1.1 on the outdoor. The metal sensor on the outdoor was off the pail and not touching the plastic. No idea really on the length of the freezing temps. Would the reading at 18" above the ground read colder than say 2" above? Aren't official weather stations taking there readings at 48" above the ground surface? A little bit concerned this morning, as readings may have been colder out in the field rather than the yard.
How is everyone else monitoring the temp when we have these situations, do you just go be the thermometer on the house?

[furrowtickler]

Yesterday morning local readings were 0 to -1 at "weather stations" and in my yard . Out in every field I went to it was -3 to -4 just above ground level from 4:30 to 6:30 . Again coldest readings were from sunrise till 6 or 6:30 depending on location .

[furrowtickler]

There were a lot of guys surprised on how much damage on some field at only 0 or -1 at their house. Even local weather stations as you said did not pick up the coldest air just above soil surface .
Damage here seems to be realy random , if it got wacked at the end of mid may frosts then again yesterday most is already gone . The other canola that has emerged after mid may frosts is highly variable - some ok some torched some not hardly touched. I think it realy deepened on the air temp just above soil surface for those 3 hrs or so .

Thanks furrow. Most of it had been zero tilled into field were the straw was taken off last fall. The rest field were worked black before seeding.

Ice in standing water , garden corn frozen, garden beans frozen. Soybeans just emerging look okay for the most part. I have not checked local reseeded canola. Was only 0.

[furrowtickler]

Surface temps on our black pea stubble were just below zero ,and on the wheat stubble -2 to -3

[blueversi]

Thermometer recorded a low of -5.6 here, was 0 at 10 pm. Definitely would have needed a sc****r for truck window at 6 this morning.

Canola appears to survive -3.5C, 90% okay at noon. Some obviously toast, randomly beside good ones. Seeded May 20-22, just emerged.
