More info in a short while. This just looks like a pause after we dialed in, almost the entire new pattern change in 1 day. This happens alot. Markets don't go up X/day in price in weather markets. They go up in huge XX surges in 1 day, when everybody sees the same thing at the same time and all want to buy(sell) on the same day......then have pauses, corrections or smaller increases(decreases) of X on all the other days...........as everybody waits for the latest weather updates to trickle in,  with individual model updates around the clock and NWS rain/temp outlooks(their interpretation of the already release model updates).

Here's their last 7 day rainfall forecast (most of it in the next 5 days, before the DOME takes over this weekend, lasing several days, then backing out, much farther west next week.

7 Day Total precipitation below:

What we know with certainty. That includes the market already dialed it into the current price.

1. The rains above will completely shut down at the end of this week. 

2. The very impressive heat dome will last several days with 100 degree heat in the Plains to WCB and NO RAIN ANYWHERE for those several days.

3. That dome backs west after that and the most bullish weather will definitely be in the WCB, closer to the dome.

What we don't know and will determine where the price goes.

1. Rain amounts this week. This is a minor factor that will cause a short term, knee jerk reaction that lasts a few hours.

2. After the dome retreats/retrogrades ,what will be the pattern? This means everything. The European Model extended forecast has been extreme bullish for the WCB for the rest of July with high heat and almost no rain. The ECB, however could have decent rains and not much heat. 

Also, their could be ridge riding perturbations coming around the periphery of the dome that models can't forecast, especially in the potential northwest flow dropping into the Midwest. 

The market has gone from being skeptical last week to believers this week because of how impressive this huge dome will be early next week( though is only lasts for a few days)

Here it is, for next Tuesday(1 week) from the 12z GEFS which is still not thru week 2 yet. That is very unlikely to be able to stay there. If that was in the forecast suddenly, we might be limit up today. Chances of it staying as a "Dome of Death"  appear to be around 10% (wild guess). 

What the market cares about for NEW INFORMATION IN PRICE DETERMINATION is where that feature migrates to and parks itself.

The latest guidance takes it more into the Southern Plains instead of the Southern Rockies. 

This was the last 12z Canadian ensemble AVERAGE model with it's individual  ensembles included so you can see the uncertainty of where that dome could go in 2 weeks.
