BREAKING – A significant Earth-directed solar flare and associated coronal mass ejection (CME) just occurred on Friday evening. There is an increasing chance of geomagnetic storms and the potential for a display of the aurora borealis (northern lights) sometime Sunday night

Cherry-picking the most extreme model solution and then posting it with only “there are many possibilities!” isn’t meteorology — it’s social media engagement farming. Hurricane season begins tomorrow. Rely on reputable sources who impart value — not engagement farmers.

BREAKING: Widespread auroral displays possible in the northern/central U.S. and much of Europe! NOAA is now forecasting a *SEVERE* geomagnetic storm – reaching G4 level on the 1 through 5 scale – on June 2. That corresponds with Sunday night/Monday morning U.S. time.

Intrigued by tomorrow's potential for one lone rotating, and potentially tornadic, supercell near Temple/Killeen along the I-35 corridor. It's looking like we might see some redevelopment along the exhaust (outflow) boundary from the morning storms. 0-3km SRH over 200 m2/s2...

Lots of uncertainty, but a decent opportunity for much of the northern Lower 48 to catch the aurora borealis (northern lights). This would probably be SUNDAY night. A quick explainer:

SUNDAY, June 1 – sneaky severe weather/tornado threat from Dallas-Ft. Worth to Corsicana to Palestine and Crockett... worth watching from I-35 to east of Highway 287/19. Storms will be *very* isolated, and only one or two might form – BUT any storm(s) could become a supercell,

Wildfires burning in western Canada are triggering poor air quality warnings in the upper Midwest, advising people with heart or lung disease, older adults and pregnant people to limit outdoor activities. Meteorologists say that this weekend the smoke, and the fine particulate
