Severe Weather's “Second Season” Severe weather doesn't vanish in the wintertime. In fact, there's a secondary severe weather peak in the fall and early winter. MyRadar meteorologist Matthew Cappucci breaks down this eerie “second season”.

🌀Cyclone Fina is strengthening as it approaches Darwin. Direct eyewall impacts are likely. 300+ millimeters of rain and winds of 130 to 170 km/h are imminent.

Cyclone Fina is now over the Cobourg Peninsula as it closes in on Darwin, Australia.

Doppler radar velocities suggest its eyewall is intensifying toward low-end Category 2 strength.

(Note: we have Australian per-station radar in the app!)

Concern is growing that Darwin could see significant freshwater flooding from Cyclone Fina.

Up to 10 inches of rain has fallen near Menard, Texas. Water is entering homes in the Harris Hollow section of town.

Yikes! Dust Storm Warning for Midland-Odessa and points east along I-20.

60 mph gusts lofting dust will reduce visibilities below a quarter mile.

Texas, Oklahoma Storms Torrential rains are continuing in Texas and part of Oklahoma. Flood watches are in effect. There’s also a marginal risk of an isolated tornado. Meteorologist Matthew Cappucci has a Thursday afternoon...

Meteorologist @matthewcappucci.bsky.social has a Thursday afternoon update.

Quarter-sized hail with a severe thunderstorm in the northwest Phoenix metro.

A flood watch remains is effect in Hill Country through Thursday night.

Keep in mind that rainfall totals will vary significantly over short distances... AND the topography could funnel water/locally enhance flooding.

In Texas, isolated severe weather is possible.

Thunderstorm fuel is sufficient to brew a couple severe storms that grow tall enough to "feel" the jet stream.

Those storms may mix jet stream momentum to the surface in the form of locally damaging gusts.

Hefty rainfall totals in Texas over these next 36 hours. Confidence is increasing in a corridor of 4+ inches of rain, perhaps around Brownwood, Brady, Fredericksburg, Junction, Menard or nearby in Hill Country. A localized 6-7 inch zone can't be ruled out.

One thing fostering heavier rainfall in Texas this evening and Thursday will be divergence, or spreading of the air aloft.

That spreading upstairs creates a vacuum effect of sorts that lifts air (and moisture) from below.

That moisture then falls as extra-heavy rain.

Increasing risk of scattered flooding in central Texas between Wednesday evening and Friday morning:

NEW: There is an increasing risk of a couple supercells, with isolated tornado potential, from northwest Tennessee and western Kentucky to southern Illinois and Indiana and southeast Missouri.

More heating than initially anticipated is leading to a bit more available storm fuel.

Polar night has arrived in Utqiagvik, Alaska, the nation's northernmost town. The sun was slated to set at 1:36 p.m. Tuesday afternoon, and won’t return until January 22.

TUESDAY, November 18th could feature a few locally severe storms in southern Illinois, southern Indiana, western Kentucky, the Missouri Bootheel or extreme northwest Tennessee.

A warm front lifting north will induce some low-level vorticity, or twist, and a few thunderstorms will form near a low.

The same storms yielded 19 reports of winds over 75 mph. There was also large to giant hail – softball-sized hail (4 inches) fell in Bloomington!

The other EF4 hit Washington *county*, passing through New Minden and Hoyleton and killing two people. It tracked 10.59 miles in just over 9 minutes. That means it had an incredible forward speed fo 60 to 70 mph!

The outbreak produced 77 tornadoes, including two EF4s in Illinois. One touched down just east of East Peoria and then hit Washington, Ill. (Tazewell County) with winds over 190 mph. It tracked 46.4 miles and killed three people.

On this date in 2013, a top-tier tornado outbreak tore through Illinois and Indiana. SPC had issued a rare high risk – a level 5 out of 5 – of severe weather, and was anticipating initial rotating supercells that would spawn tornadoes and then merge into a destructive wind-producing squall line.

A hefty dose of moisture in southern California with this next atmospheric river... but it could even bring some flooding.

An atmospheric river will soak central and southern California over the next several days, with the heaviest beginning Saturday morning.

2 to 3 inches of rain is possible in Southern California, with 2-3 FEET+ of snow in the Sierra Nevada above 6,000 feet!

The sunspot that gave us epic auroral displays is finally rotating away from us – but not before spewing another big flare.

This one's associated energetic shockwave (coronal mass ejection) is likely aimed away from us, so it won't cause more big geomagnetic storms.

8:30 PM ET Aurora update:

YouTube video by MyRadar Weather News What the Colors of the Northern Lights Really Mean

Ever wonder why the northern lights shimmer in green, purple, and red?

The colors aren’t random — they reveal which gases in our atmosphere are colliding with solar energy.

Believe it or not, there is actually a science behind what the aurora will visibly look like at your location IF a high-end geomagnetic storm materializes as forecast:
