A severe thunderstorm watch has been issued for parts of Colorado, Kansas and Nebraska until 10 PM MDT

A "storm highway" is possible from the West to the South and East Coast next winter as El Niño supercharges the subtropical jet stream. Chances for extreme rainfall and severe storms will probably both be much higher than normal. Not looking like the best winter to head south!

Breaking News! Code: y-axis alert! As of July 5th, the Nino 3.4 sea-surface temperature anomaly has now crossed 1.80°C above the 1991-2020 mean. ' The Nino 3.4 SST is now 3.46 standard deviations above the 1991-2020 mean:

A surprise thundershower up in Fort Collins. Only lasted a few minutes. Some soft hail also. 330pm. #cowx @BianchiWeather @CBSJoeWeather @NWSBoulder @CReppWx

@CBSJoeWeather here's a pic of the smoke from the 300 acre fire west of Leadville near Hagerman Pass, taken by my brother in law who works at 12,000' on the west side of the pass.

Round two of large hail producing thunderstorms will affect the I-25 corridor from now through 2 AM, and will affect eastern portions of the southeast plains from around midnight through 4 AM. Very large hail, damaging winds, and even an isolated tornado will be possible. #cowx

#skstorm #ndwx may be producing a tornado now. Approaching Oxbow 7:10PM #stormhour

@MatthewCappucci Not all stations, CBS Colorado lets us chase the weather, and report in it. From fire to blizzards. This was today near Kiowa, CO. 1 met in the studio, I head out in the field.

TV news needs to be informative, entertaining or edifying. Doing the same seasonal packages we did in 1997 isn’t going to work. Plus it’s boring. There’s not a ton of original reporting left in local TV anymore. Find/tell some real stories and re-earn the public trust.

Most TV news stations are lazy. Mindless fluff is easy. “It’s hot — drink water” isn’t a story. Neither is a reporter interviewing people at a waterpark. Nor the bread and milk reporters or the big pile of salt reporter before a snowstorm. No wonder TV news is dying.

Tornado sirens going off in downtown Denver att 4:05 this afternoon. #COwx. Radar doesn’t indicate anything resembling tornadic activity downtown and no tornado warnings @StoryfulViral @JadenKnowles2 @CBSJoeWeather @CReppWx @KylieBearseWX

There has been quite the confusion about the arrival time of this CME! Here it is explicitly broken down by popular time zones. For North Americans, please note that when I say "Sunday night" in my posts, this INCLUDES Monday morning. Sunday night = June 8 UT day, Monday night = June 9 UT day. The G3 watch is for Monday UT day which is effectively Sunday night since 0 UT starts at 8 pm EDT. Official forecasts from NOAA SWPC are given in UT (Universal Time). This is the same as GMT, UTC, and Zulu time. Your aurora app may automatically convert the UT time zones to your local time zone, so be aware of that.

A G3 geomagnetic storm Watch has been issued for 8 Jun, and a G2 geomagnetic storm Watch has been issued for 9 Jun for the anticipated arrival of the CME that left the Sun on 6 Jun. Stay tuned for updates!

AR 4461 produced an M1.8 flare at 06/1401 UTC. This event was associated with a filament eruption and subsequent CME of which analysis and modeling is currently underway. An Earth-directed component is currently anticipated and would likely arrive on June 8th by rough estimates.

G2 geomagnetic storm levels reached following the likely arrival of the anticipated CME(s) from 3 Jun. Stay tuned for updates!
