I think I like this more.

Good stuff. Interesting is the position of precipitation bands compared to fronts and that shift in the wind e.g. from Kansas to Nebraska.

It will be interesting to see this potentially historic winter storm in your analyses.

And that tiny red dashed boundary over Montana and Wyoming – how did you catch that?
January 19, 2026 at 5:34 PM
Another fascinating map! 1) We said those dashed lines are kind of weaker fronts or troughs in either cold or warm air? What does darker vs. lighter blue mean? 2) How did you decide that front over SW US is a stationary one, i.e. how did you decide to orient the triangles and semicircles?
January 19, 2026 at 5:34 PM
Very probably that is it. Same happens for frontal systems in Canada’s far and nearly uninhabited north e.g.

Do you perhaps know when the WPC draws troughs such as these over the Gulf and south of Cuba, how do they detect them – no stations around, no kinks in the isobars?
January 18, 2026 at 3:58 PM
Which would make total sense, because an occlusion kind of is exactly that. Do you have any pointers on how would you identify it on a station-model chart without looking at any other maps, charts, or images?

I wonder if you would designate as occlusion that snow-producing line around that low above Ungava Bay. There’s another low near-by.

Always much appreciated! That waving front across the Balkans is really interesting and is a heavy precipitation maker (snow, sleet, rain, even freezing rain).

There’s also a ‘stationary front’over The Bahamas and another one not too far off from that first one in the Atlantic. Dunno how the WPC saw that one.

What a cute little warm front over the Mitten of Michigan.
December 29, 2025 at 3:26 PM
Airmass RGB GOES imagery shows distinct difference between the mass over land and just as you set foot over the Gulf. The boundary was drawn on WPC maps a few time slots ago, but has since disappeared.
December 23, 2025 at 2:31 PM
🙂 That's why I think it is important for everything, or at least as much as possible, to be drawn.
December 23, 2025 at 12:51 PM
If you look at the WPC NWS interactive surface analysis, it is a trough today. I think it was there yesterday as well. Often I come upon phenomena that might not fit the main conceptual models (cold, warm, occluded front etc.). So I wonder what is what.

… it, maybe we can see Christmas across the world through synoptic charts. BTW, thank you so much for creating them and posting them and doing so regularly – they are a revelation and a joy to see. I cannot wait for the next one. Love them.
December 22, 2025 at 4:43 PM
You know what else? I’m not sure I would be good at curving, bending these fronts the way you do. I wonder if I should just trace them across kinks in the isobars or if there is more… And then picking the colour of a dashed line – hm… There is work here. Thank you for posting! And if you’re up to…
December 22, 2025 at 4:42 PM
What is that mass of cloud off coast of Mexico in the Gulf – some kind of a trough? It can perhaps only be seen a tiny bit on the map above.
December 22, 2025 at 3:22 PM
When I check a map for those dashed lines, which were something like weak boundaries in either cold or warm air?, I wonder if I would have been able or if had I had drawn them if the map were given to me. I am sure I would have missed them. Yikes.
December 22, 2025 at 12:06 PM
I forgot that I asked below these maps, and you often overlay fronts over MSLP/precip rate/relative topography. Sometimes some phenomena are easy to spot, at other times…
December 15, 2025 at 10:55 AM
How do you make the isobars so smooth? 🙂
December 15, 2025 at 10:53 AM
Google seems to be beating both.
December 15, 2025 at 10:53 AM
When you overlay fronts on a map such as this, you use other maps as well to diagnose their position?
December 14, 2025 at 3:24 PM
Have you seen the announcement on the new MO modelling system?
