Day 1 - wow

So the 12Z information is coming in. I'm having a moment here.

250 mb - a good jet streak is evident at Albuquerque, NM. 90 knots is what it appears to be. That will provide plenty of ventilation for storms that go.


500 mb - 80 knots coming in there. And the approaching temperature is -14, as compared to -10 at Dodge City.


700 mb - 35 knots, but on this one the big story is the crazy cooling coming in--from +8 to -1.


850 mb - soundings all over the place show deep, substantial moisture.


Surface - there's a low in southwest Kansas with a warm front northeast from it and a dryline to the south. Where the two meet is called the triple point, and that's an area of tremendous convergence and shear. That's where we're going.

SPC has a slight risk of severe thunderstorms for the area, with a hatched area (10% chance of EF2-EF5) centred on the triple point. I suspect that, later today, they will upgrade to a moderate risk. In addition to tornadoes, possibly strong, today, the tremendous cooling and thus destabilization coming in tell me that there's a good chance of very large hail. Stay away from it.

Follow us along on Spotter network. We're called Winnipeg chasers.

I'm quietly optimistic about today.
