Hail!!!!

I was educated yesterday, regarding severe weather in Southern Alberta. A couple of days ago a person was killed at the Big Valley Jamboree when a massive wind gust blew down the concert stage. The wind that caused the damage was called a "plough" wind, and preceeds a thunderstorm. It's basically a powerful downdraft wind that spreads out in all directions like water pouring from the faucet when it strikes the sink. It can reach speeds of 100kph, which is almost hurricane velocity, and 1/3 tornado velocity. The same downdraft blew through downtown Calgary, and tossed plywood sheets off of construction towers onto the streets. A 3 year old girl was killed when she was struck on the head by a piece of metal flying off a building!
A friend of mine was on the Bow River when the downdraft hit, and Calgary Fire Rescue pulled him and his family to safety. So, these downdrafts can be deadly, even though they don't last very long.

We experienced this twice over several days. No major damage occurred from the winds, but the thunderstorm last night brought hail, which basically pulverized my vegetables. Some of them look like they might make it through, which is encouraging, but all of them sustained pretty severe damage, except the tomatoes, which were getting out of control anyway.

I have come to the conclusion that I need a permanent system to deal with hail, which is a constant presence out here on the flat prairies. We very much need a shelterbelt around our house area, which of course takes time to establish. I also plan to build a metal framed mesh around my garden tires, made of bent 5 foot rebar with chicken wire stretched over it. The chicken wire should deflect most of the hailstones and reduce the damage significantly. It's also inexpensive, and lasts a very long time. The rebar will be bent in a curve or two bends (whichever works best), and tied to the chicken wire. I could also stretch plastic over this and make a very decent mini-greenhouse in the spring, perhaps starting the seedlings a week or two early.

I really pray that my plants will recuperate from the hail, which will surely knock them back in growth by a week or two.

The workshop/shed/barn project is progressing well, with tommorow being the excavation day. I staked out the 42 x 24 foot area and cut all the vegetation down to make it easier to see. I purchased some thick cable for the electrical circuit, and ran it out to the edge from the house. I want to be able to just dig the trench, bury the wire, and rebury it right away. I only have the machine for 1 day, so I have to be completely prepared!

Look for pictures as I complete the digging.
