Significant severe weather is coming back on Sunday. Hurricane force damaging winds, and tornadoes will be the threat. Be sure to pay attention! I will be covering this event.

A quickly-intensifying storm system will bring a dose of meteorological March madness — with a blizzard, tornadoes, fire weather, damaging gusts, and an ice storm. The seasonal clash crescendoes Sunday and Monday.

Wow! This is the rapidly-rotating wall cloud as it spawned a tornado near Pontiac, Illinois on Tuesday as seen by @matthewcappucci.bsky.social.
The same storm would later produce "gargantuan" 6-8 inch hail and multiple strong, deadly tornadoes.
A clipper system is gearing up to bring snow to the Upper Midwest, northern Great Lakes, and Northeast. The storm will also bring strong winds of 40 to 60 mph.

We anticipate some thundersnow in Wisconsin tonight along an occluded frontal boundary. High-resolution models are also signifying some lightning potential with this activity:
Blizzard warnings now hoisted in North Dakota and along the shores of Lake Superior in Minnesota. Widespread plowable snows, but with 60+ mph winds!
Plan for scattered power outages. Truckers should be extra careful and know when it's not worth driving high-profile vehicles!
Gusts of 70-80 mph in parts of Montana and western North Dakota, with 60+ mph gusts in western Minnesota (maybe a few gusts to 70 mph)! Otherwise LOTS of folks get 50-60 mph winds into Friday.
WIND BAG of a system coming to the Upper Midwest and Great Lakes between Thursday night and Friday. This comes behind a strong low pressure system bringing snow and blizzard conditions to parts of North Dakota and the Upper Peninsula of Michigan!
Snowfall rates briefly exceeding 2 inches per hour are possible at times! Granted most of the snow will melt either immediately or quickly thereafter given warm ground temperatures.
There could be some isolated, sporadic lightning strikes as a result; any ground strokes would be disproportionately likely to strike tall human-made towers (radio, television, cell), skyscrapers and/or wind turbines.
Models are hinting at some instability, or thunderstorm fuel, and rapidly-dropping temperatures along the front should allow rain to flip to heavy, wet snow.
THURSDAY, March 12, 2026 could feature thundersnow in the Mid-Atlantic as the atmosphere cools FAST behind a front. It's the same front that brought tornadoes/melon-sized hail in Illinois. Now it's scouring out the warm air; Washington D.C. could go from 80 degrees to SNOW in 24 hours!
In severe weather, minutes can mean millions.
That’s exactly what we mean when we say MyRadar is built to keep you ahead of the storm.

That lead time gives organizations time to move vehicles, protect assets, and reduce operational exposure before the hail arrives.
Large hail causes billions of dollars in insured losses every year in the United States.
At 5:48 PM, MyRadar meteorologist @matthewcappucci.bsky.social documented a hailstone over 5 inches in diameter from that same storm, verifying the hail-producing core the model had already identified.
Yesterday evening near Buckingham, Illinois, MyRadar’s Hail Nowcasting model identified a hail core capable of producing 5+ inch hail.
The model initialized at 5:38 PM CDT, projecting the storm’s hail core location through 5:54 PM CDT — 16 minutes of forward projection.
"As I saw it coming, I said a quick prayer."
Scott, a resident of Lake Village, Indiana describes what it was like as a powerful tornado moved through Tuesday night.
MyRadar storm chaser @jordanhallwx.bsky.social spoke with him the morning after the tornado touched down.
A lengthy squall is pushing eastward along a cold front. It is affecting parts of the Midwest, the Mid-South, and Mid-Atlantic.
Damaging gusts and a few tornadoes are possible.

Just how big can hail get?
While storm chasing in Illinois, senior meteorologist @matthewcappucci.bsky.social encountered DVD-sized hail estimated between 5–6 inches in diameter — possibly large enough to challenge the state record.
Search & rescue crews sift through tornado debris in Kankakee, Illinois after a tornado tore through the area late March 10, 2026. Crews searched damaged structures and rubble overnight in the storm’s aftermath.

A FIVE INCH HAILSTONE has been found near Buckingham, Illinois by senior meteorologist @matthewcappucci.bsky.social as he frolics through farmland.
This may be the state record if confirmed!
Meteorologist @matthewcappucci.bsky.social reports tennis ball-sized hail just west of Cabery, Illinois.
⏱️ 22 minutes.
That’s how much lead time the MyRadar Hail Nowcasting model provided before this storm moved into Abilene, TX.
Our advection model tracks developing hail cores and projects where they’ll be before they arrive.
When storms intensify fast, that lead time can make all the difference.
Rotating supercells could produce hail and a few tornadoes in Texas/Oklahoma before transitioning into windy lines/clusters. Some of the hail may be large and damaging.
Meteorologist @matthewcappucci.bsky.social has a severe weather briefing.
An UPGRADED tornado risk has occurred in northern Illinois and northwest Indiana. If you live between Galesburg, Peoria, Kankakee, Bloomington, Champaign, Rochester or Renssalaer, Indiana, please review your severe weather plan ASAP!
NEW: A Level 4 out of 5 severe weather risk has been introduced in the red zone across portions of north central Illinois and adjacent western Indiana.
Several tornadoes, including a couple strong and/or long -track, are expected.
JUST IN: The SPC has upgraded parts of Illinois and Indiana to a Moderate Risk (4/5, red) with a 15% 'CIG2' hatch area.
This means storms have the potential to produce EF3+ tornadoes.
Take today very seriously.
Rotating supercells will form in Illinois/Indiana this evening. Where temperatures are warm, significant tornadoes are possible. Where they’re cool, large, damaging hail could occur.
