Disturbance in the Caribbean

A pocket of spin, known as the Central American Gyre, could consolidate in the Caribbean. That might lead to a named storm forming this weekend or early next week. Odds are around 50 percent. MyRadar meteorologist Matthew Cappucci breaks down the setup.

This is the zone at greatest risk for an isolated strong tornado.

That's predicated on any lone, discrete supercells forming ahead of a main squall line.

That's always a wildcard in setups like this. The odds of it happening are low, but if it does happen, serious results.

Scenes of piled-up vehicles in Valencia, Spain today after yesterday’s devastating flooding.

We have a big area of humid air in the green, with dew points in the 60s. That marks the unstable, or juiced-up, air within which thunderstorms will blossom.

A pair of fronts – a dry line and a cold front – will kick that moisture upwards, causing severe storms on the Plains.

Don't look now, but even after today's risk, we've got more severe weather to talk about this weekend.

The Storm Prediction Center has highlighted threat areas for Saturday and Sunday too.

An Enhanced Risk has been issued for much of Kansas. a 10% hatched region for STRONG Tornadoes has been added as environmental conditions look conducive for development. Be sure to pay attention to all watches and warnings.

Snow already occurring near Donner Pass in the Sierra Nevada!

The Central Sierra Snow Lab averages 30 feet of snow per winter season.

they had 1" (2.5 cm) of in the last 24 hours and are expecting a bigger storm later this week. This vid was captured yesterday when rates were peaking.

Ahead of the line, winds will be changing speed and direction with height. IF, and that's a big IF, any storms are able to pop ahead of the line, they'd likely rotate and could produce an isolated significant tornado. However, it's unclear if storms will be able to fire ahead of the main line.

That's why tomorrow will likely be a "boom or bust" day, as is often the case in the cold season. Stay weather aware!

There is an increasing risk of severe weather across portions of the Plains tomorrow.

Kansas City has a "conditional" risk for an isolated significant tornado, as does the I-44 corridor northeast of Oklahoma City.

The setup is simple: a front is marching east into warm and humid air. Dry air behind the front will kick the moisture upwards into storms. Strong jet stream winds will add momentum, and any storms will be capable of producing damaging wind gusts.

Central U.S. fire danger

Warm, dry and windy conditions will lead to extreme fire danger for portions of the Plains, Corn Belt, Great Lakes and Midwest. MyRadar meteorologist Matthew Cappucci breaks down the risk.

Severe Storms On The Plains

A multi-day episode of strong to severe thunderstorms is possible across the central Plains on Tuesday and especially Wednesday. Damaging winds and large hail are the main concerns.

MyRadar meteorologist Matthew Cappucci has a severe weather preview.

MyRadar Winter Outlook

What will this winter hold? An emerging La Niña pattern will contribute to a warm and wet winter for much of the central and southern U.S.; the Pacific Northwest and northern Rockies could be colder and snowier. MyRadar meteorologist Matthew Cappucci examines.

There is an increasing risk that the Central American Gyre, or a broad zone if diffuse spin that will be present in the western Caribbean, could squeak out a storm next week.

If vorticity (spin) tightens, we could see a named storm form around Halloween.

Why is it so incredibly dry in the Mid-Atlantic?

Look at where the wind is coming from compared to average — much more out of the NW and not the S.

Fire danger and drought in the Northeast

Hardly a drop of rain has fallen across portions of the Mid-Atlantic and Northeast, leading to emerging drought and fire weather. MyRadar meteorologist Matthew Cappucci breaks down the latest.
