It looks like the region stays cold the majority of that next week. More rolling blackouts from TVA?

May not have to worry about that if it’s a crippling ice storm.

Nice to be able to track something.

My weather chanel app went from 1 to 3 inches Friday night 1 to 3 Saturday and 1 to 3 Saturday night to now it say 1 to 3 Friday night 5 to 8 Saturday and 1 to 3 Saturday night that would shut nashvegas for few days lol

Weather/Hazards Highlights...

Another day of lake effect snow is likely across the Great Lakes
Thursday, with potentially heavy amounts piling up downwind of Lake
Ontario after a snowy short range period too. Meanwhile, some
light to moderate rain is forecast across the Southeast Thursday,
while the low aloft could help produce some precipitation across
southern California. Then precipitation is forecast to spread
across parts of the Southwest, the southern/central Rockies, and
across much of the southeastern U.S. into Friday. With the cold air
in place, ice and snow are likely across much of the southern tier
in likely a notable winter storm. The precipitation, including
snow and ice, is forecast to spread east into the Carolinas and
Mid-Atlantic on Saturday, lasting until Sunday and potentially
spreading north into the Northeast. Model guidance has converged on
the potential for an impactful storm, but it will take additional
time to refine the details of precipitation amounts and type, so
continue to monitor forecasts. Elsewhere, precipitation could
increase across the Pacific Northwest and northern Rockies this
weekend as shortwaves move through.

Models have been very inconsistent and uncertainty is high for the latter periods, but there is general agreement that a system will
bring more precipitation to the area sometime in the Friday/Saturday/Sunday time frame. Right now models suggest a mixed bag of precip types, with both rain and snow possible, but given how far out it still is as well as the poor model agreement and consistency, we will need to monitor and wait for more clarity on
the details as we get closer.

Goes completely against the other discussion lol

Overnight ensembles are juicy. Lots to be ironed out but you can clearly see the classic CAD boundaries setting up. Hopefully the zr outputs end up being a lot of sleet.

 

the NBM shows the footprint well.

What the!?!

Random 3am wishcast thoughts, that I'm not rolling out of bed on a Monday AM to type at 3am:

1. Does the relative coarseness or smoothness of the resolution of the higher res OP Euro vs Euro AIFS impact how it resolves the the Baja low?

Example:

 

2. Although once the Euro AIFS locked in for the past weekend system it ticked NW, this is a different set up. The AIFS began to resolve the specific details in the shorter ranges and the room to wiggle there was NW with a s/w digging more. In this scenario does the cold high perhaps verifying stouter closer to go time do the opposite and work against the low wanting to cut poleward? 

 

3. And finally, here's some real weenie hopium: Does the fact that the Euro AIFS is trained on lots of old data means it is more likely to see more common scenarios, like the Miller A/B hybrid it depicts at 6z, than a once in every 50 years southern slider like Jan 1988?

 

 

Not gonna lie, I'm pretty set on a Miller A/B hybrid now (pretty much based on the Euro AIFS still trending more amped and north) with a low cutting up through the East TN Valley and hoping for less ice in that situation. I will take a cold rain over ice 100% of the time.

Ticked north a bit:

Here's a comparison on weatherbells graphics of the 6z Euro and 0z Euro:

Note the shortwave the higher res Euro picks up diving in through the Dakotas. That would work to keep some suppression in play

Here are the 6z EPS members for your viewing pleasure:

Still depicts a disruptive, plowable snow for most all of the state.

And I will add, we will probably make a run at zero or below those that have a snowpack for Monday morning next week
