Interesting that the AI ensembles wash out the troughing like the non-AI versions of the operational runs.

Extreme Heat Warning issued: URGENT - WEATHER MESSAGE National Weather Service Portland OR 913 PM PDT Thu Jun 11 2026 ORZ109>112-120-WAZ206-207-209-121900- /O.UPG.KPQR.XH.A.0001.260614T1800Z-260617T0600Z/ /O.NEW.KPQR.XH.W.0001.260614T1800Z-260617T0600Z/ Tualatin Valley-Portland West Hills and Chehalem Mountain-Inner Portland Metro-East Portland Metro-West Columbia River Gorge I- 84 Corridor-Inner Vancouver Metro-East Clark County Lowlands-West Columbia River Gorge SR 14 Corridor- Including the cities of Multnomah Falls, Tigard, Happy Valley, Washougal, Portland, Gresham, Sylvan Hill, Eagle Creek, Camas, Stevenson, Forest Grove, Chehalem Mountain, Oregon City, Cascade Locks, Vancouver, Salmon Creek, Rooster Rock, Lake Oswego, Beacon Rock SP, North Bonneville, Bonneville, Cape Horn, Troutdale, Sellwood, Fairview, Hillsboro, Skyline Drive, Sherwood, Evergreen, and Rockcreek 913 PM PDT Thu Jun 11 2026 ...EXTREME HEAT WARNING IN EFFECT FROM 11 AM SUNDAY TO 11 PM PDT TUESDAY... * WHAT...Dangerously hot conditions with temperatures between 95 and 100 degrees F expected. * WHERE...Portland Metro Lowlands, Western Columbia River Gorge, Portland West Hills and Chehalem Mountain, Inner Vancouver Metro, and East Clark County Lowlands. * WHEN...From 11 AM Sunday to 11 PM PDT Tuesday. * IMPACTS...Heat related illnesses increase significantly during extreme heat events. * ADDITIONAL DETAILS...Peak heating days will be Sunday and Monday with a slight cool down on Tuesday. Overnight temperatures will remain elevated Sunday night into Monday morning, and Monday night into Tuesday morning. Night time temperatures ranging from 63 to 67 degrees F will lead to poor overnight relief. There is currently a 20-30% chance that night time temperatures remain above 70 degrees Sunday night into Monday morning, and a 5-10% chance Monday night into Tuesday morning. PRECAUTIONARY/PREPAREDNESS ACTIONS... Drink plenty of fluids, stay in a cool place during the heat of the day, stay out of the sunshine, and check up on relatives and neighbors. For those without air conditioning, use fans to keep air moving. Keeps windows closed during the day and open at night, unless air quality is degraded. Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes. Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1. Stay cool, stay hydrated, stay informed. Monitor the latest forecasts and warnings for updates. If you do not have air conditioning in your home or lack shelter, you can call 211 for assistance locating appropriate shelter from the heat.

Mariners stink again!

Here's a screenshot of a video of damage from Merrillville. This is one of the more substantial damage pics I have seen from there up to this point. Based on the totality of the evidence from across Merrillville, I'd certainly be pretty confident in saying this tornado was at least EF-2. The question is whether there will be anything to justify a higher rating.

Big test for the new AI models coming up after the heatwave. Physics models are leaning on thermal runaway ridging, AI models cleanly swoop in the trough from the NW.
