For everyone on the east cost, be safe out there, nasty weather today

Severe storms are expected across parts of the Mid-Atlantic today, with damaging winds and an isolated tornado possible. A rare Level 4 out of 5 severe weather risk has been issued for parts of the region. MyRadar meteorologist @matthewcappucci.bsky.social breaks down the forecast.

A heat dome is expected to build across parts of the western U.S., sending temperatures soaring in the Southwest. Some locations could approach 100° nearly two months ahead of schedule, potentially challenging early-season records. MyRadar's @willcanowx.bsky.social breaks down the forecast.

How wackily dynamic is this system? Missouri is simultaneously dealing with tornado warnings AND snow squalls. Yep.

SUN PM update: D.C., Baltimore, Fredericksburg, Culpeper, Richmond, Virginia Beach, Norfolk, Charlottesville... be ready for multiple rounds of storms with possible tornado risk on MONDAY, March 16. PLEASE SHARE with friends/family!

🌪️A multiday outbreak of destructive winds and tornadoes looms Sunday evening through Monday. A very rare Level 4 out of 5 severe weather risk has been drawn in the Mid-Atlantic! @matthewcappucci.bsky.social has a briefing. myradar.com/videos/6398

Memphis, Jonesboro, Paducah, Paragould... some of our high-resolution models are hinting at the potential for a few discrete rotating supercells AHEAD of our squall line. This risk will be maximized near the Mississippi River. If this occurs, increasing risk of isolated significant tornado.

SERIOUS SEVERE WEATHER: The Storm Prediction Center has UPGRADED to a rare Level 4 out of 5 severe weather risk for Monday in the Mid-Atlantic. This includes Washington D.C., Richmond, Raleigh, Charlotte and part of South Carolina!

TONIGHT, Sunday night, March 15-16 – damaging to locally destructive straight-line winds with this squall line that will blast through the Mississippi Valley! These storms will contain 60 to 75 mph straight-line wind gust and likely a few tornadoes!

This is kind of wild... level 1 out of 5 marginal risk for hail AND Des Moines/Cedar Rapids are under a blizzard warning AND models are suggesting some of the initial hail-producing thunderstorms might also deliver freezing rain... M'kay.

Mid-Atlantic gang – MONDAY has an upper-echelon "parameter space" for rotating storms. That means the combination of storm fuel (instability) and spin (shear) is rare for this area, and could support supercells with a tornado risk.

Mid-Atlantic gang – Monday, March 16 is looking increasingly nasty weather-wise, with the potential for an upper-echelon severe weather event. SPC is considering upgrading to a Level 4 out of 5 risk, which hasn't happened since August 7, 2023. It happens 2-3 times per decade on average.

SUNDAY night, March 15-16, will feature the potential for a dangerous thunderstorm squall line in the Mississippi Valley. Here's our detailed writeup and the risk area:

A viral account claims there’s a 95% chance of a major earthquake in Los Angeles. But earthquake predictions like that simply don’t exist. Meteorologist @matthewcappucci.bsky.social spoke with the person behind the account and explains what real seismology says. https://myradar.com/videos/6397

SUNDAY NIGHT, March 15-16, will feature the risk of nocturnal dangerous storms in the Mississippi Valley. You'll want to keep your phone on/weather radios ready in order to receive weather warnings.

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. @myradar.bsky.social #weather #wxsky

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. @matthewcappucci.bsky.social has a briefing. myradar.com/videos/6396

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. @matthewcappucci.bsky.social has an update. myradar.com/videos/6395

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!

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!

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!

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. @matthewcappucci.bsky.social has a severe weather briefing. myradar.com/videos/6393

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. 📹: @jordanhallwx.bsky.social/MyRadar

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. @matthewcappucci.bsky.social has a severe weather briefing. myradar.com/videos/6388

NEW: SPC is now cautioning that INTENSE tornadoes (EF3+) are possible THIS EVENING in northern Illinois/Indiana/southern Michigan! Confidence is increasing in the potential for supercells to ride the warm front eastwards, gobbling up ample low-level spin and becoming dangerously problematic.

TEXAS-SIZED HAIL possible THIS EVENING (Tuesday, March 10)! This map does not show the likelihood of hail, but rather the MAX SIZE *if* rotating thunderstorms become established and can take advantage of the environment.

Warm fronts tend to impart extra low-level helicity, or twist, on storms, bolstering rotation. That, in tandem with an environment already supportive of spinning storms, supports several intense, long-track supercells in Illinois/Indiana with hail or tornadoes.

Today (March 10) will feature a VERY dramatic difference in only a few miles if you live near the shores of Lake Michigan. And if you live in Chicago, there is the CHANCE of some big hail.

TUESDAY, March 10 – IF a storm can become established on the south side of a stalled boundary in central Illinois, and root itself in warm air, oof... the environment would be VERY conducive to powerhouse tornadoes... perhaps in the EF2 to EF3+ range.

TODAY, March 10 should feature the risk of significant severe weather – including perhaps a few strong tornadoes and large, damaging hail – in Illinois and perhaps Indiana.

UPDATE: The SPC has upgraded a portion of Texas to an Enhanced risk (3/5, orange) for severe weather on Tuesday. As @matthewcappucci.bsky.social mentioned below, there’s a sneaky shot at some strong tornadoes (EF2+) around the DFW metroplex.

TOMORROW: A broad, multi-faceted severe weather event is likely Tuesday from the Midwest to the Rio Grande. Damaging gusts, very large hail and a couple tornadoes, some significant, are expected. Senior meteorologist @matthewcappucci.bsky.social has a severe weather briefing.

A few supercells are possible across parts of Arkansas, northern Louisiana, Mississippi and Alabama. Hail up to egg size is possible, along with a tornado or two. Senior meteorologist @matthewcappucci.bsky.social has a severe weather briefing.

We can't forget about the hail risk on Tuesday. Dual zones where hail could be large and damaging... both parts of the Corn Belt/Midwest and Texas:

MONDAY, March 9 – A Level 2 out of 5 Slight risk of severe weather covers much of Arkansas and northern/central Mississippi and Alabama. A warm front lifting north is introducing warm, humid air, and the amount of instability, or thunderstorm fuel, is building.

TUESDAY, March 10 has the potential to feature scattered to widespread severe weather across much of the Midwest, Corn Belt, Plains and even Texas. Some tornado activity is likely.

BREAKING: The Union City, Michigan tornado has officially been rated AT LEAST a 150 mph EF3 with winds of 150+ mph. Path length, width, start/end time etc. have not yet been ascertained, and it's possible the damage path may have been the result of multiple touchdowns.

A storm system rolling east is continuing to bring the risk of severe weather. In western NY, PA, OH, & WV, there’s a tornado risk. In Texas, a couple of supercells with hail up to egg size. @matthewcappucci.bsky.social has a severe weather briefing. myradar.com/videos/6385
