Up to 50m people could be affected by back-to-back bomb cyclones that will release rain, snow and powerful winds across most of the country from California to New York

Damaging winds, hail, isolated tornados, and floods are threating to impact more than 50 million people from California to New York over the weekend and early into next week.

The back-to-back bomb cyclones are forecasted to create atmospheric rivers. Atmospheric rivers are long narrow regions of moisture in the atmosphere 'like rivers in the sky' that release rain or snow to the earth, according to the National Oceanic and Atmospheric Administration.

A storm is considered a bomb cyclone when its minimum air pressure drops 24 millibars or more within 24 hours; this next storm could decrease by 50 millibars potentially becoming a 'double bomb.'

Thanks Metmom. Yes, the MSM is who are sensationalizes the meteorological terms. Your average NWS discussion is like watching paint dry...

.SYNOPSIS... A warm front will pass north of the region tonight, then drop south late Monday as low pressure begins to rapidly develop south of Long Island. Strong low pressure affects the region Monday night into Wednesday. Weak high pressure will briefly return Wednesday night and Thursday before another large and slow moving low pressure system impacts the area Thursday night into next weekend.

.NEAR TERM /THROUGH MONDAY NIGHT/... Sfc analysis shows a developing warm front across PA. As high pres over the cwa drifts offshore, the warm front will approach tngt and provide a focus for rainfall. The models have been in good agreement centering the best rain chances and highest amounts across the nrn half of the cwa, and this consensus was followed for the fcst.

With the warm front progged to be just north of the area on Mon, low clouds and lgt rain or dz invof the front will be a fcst challenge. For now, we have trended the fcst towards the NAM, but not all the way as the NAM does tend to hold onto too much llvl moisture at times. The srn third of the cwa is expected to break out of the clouds by aftn which would allow temps to shoot up into the mid 70s. Where the clouds and lgt pcpn do not clear, temps will stay in the low 60s and even upr 50s. Most of the area attm is expected to break out by late aftn per the model consensus, but with a sharp boundary the consensus may not be good enough. As previously mentioned, the fcst has been hedged cooler with the NAM, and a temp bust on either side is possible.

Pwats will increase to around 200 percent of normal on Mon ngt. At the same time, an h5 low over the midwest and one over Canada are progged to merge and approach the area. This scenario would result in the blossoming of hvy rainfall across the area. Model time heights, particularly the NAM, show deep, intense lift which would support hvy rainfall rates given the moist environment. Given this scenario and the potential for additional rainfall as the storm intensifies on Tue, a flash flood watch has been issued.

Embedded tstms possible Mon ngt, but attm they are expected to be elevated with the llvls stabilizing, so the SPC outlook of mrgnl or less looks appropriate.

Winds begin to increase late Mon ngt as the low begins to deepen south of LI. Speeds however are expected to remain blw 25-30 mph thru Mon ngt.

It is so bad that ... the fans in San Franfreako are covering themselves with plastic bags to watch the football game in the outdoor stadium. You can see it on TV!

Bomb cyclone is at least 40 years old: https://journals.ametsoc.org/downloadpdf/journals/mwre/108/10/1520-0493_1980_108_1589_sdcot_2_0_co_2.pdf

LOL!! I heard the pipes screaming as my bomb cyclone passed through them🌀🤣

[palmer]

Three inches is almost an entire months worth of rain here in the northeast.

Except we are talking about the west coast where an inch of rain a day in October is not uncommon.

[metmom]

CA to NY is a a small part of the forecast?

[RinaseaofDs]

A porcelain punisher. A toilet terrorist.

[metmom]

True that.

It’s like listening to Mr. Spock describe something.

[TigersEye]

No. The NE is a small part of the area from CA to NY.

How many “wind turbines” will be destroyed by the “bomb cyclones?”

I trust the WX Bell team over anyone else, Downs, Deleo and Bastardi know their stuff and don’t agendize it. I am a subscriber.

[Polar Vortex!!!]

Is that where all the Polar Bears with their Coca-Cola bottles become like a Sharknado?

[Shady]

We are almost a rain forest anymore, I’ll take it, no droughts here!

[CFW]

In other words, “Winter will be arriving this coming week”!

Thanks for the link. I’ve honestly never heard the term before.
