Remember, even if the Atlantic hurricane season ends up being below to near normal, it only takes one storm in your community to make it a bad hurricane season for you. Prepare this year like you would any other!

Many severe thunderstorms and tornadic supercells erupt from Texas to the Great Lakes.

Cannot believe this just happened. Close range intercept near Kankake, Illinois. Lost glass and grille.

Here are our Key Messages for Tuesday (3/10).

[NWS Weather Prediction Center @NWSWPC]

Confidence continues to increase on an expansive major winter storm impacting much of the southern and eastern portions of the Country Friday through Sunday. Key Messages are updated.

[Da'Vel Johnson @Da_VelJ]

After Monday's cold front, DC and the Northeast won't see 45 degrees for quite some time. 👎🏾

[Floyd Green @floydgreenja]

Good morning,

Most communities are currently without electricity,as a result you might be unable to get through to your families. We are hoping they will be able to send through calls and messages soon.

The amount of vegetation and power infrastructure loss will take months even years to recover.

The satellite derived wind field really puts the storm scale into prospective. Around half the Jamaica will see #hurricane force winds from #Melissa, but several parishes (Westmoreland, Saint Elizabeth, Manchester, Saint James, Trelawny) will see extreme winds over 95kts/110 mph.

[Da'Vel Johnson @Da_VelJ]

Preparation should be completed today as worsening impacts begin Sunday and Monday into early next week (10/26-10/30).

[Da'Vel Johnson @Da_VelJ]

With the model guidence showing more agreement this afternoon, it confirms that Tropical Storm #Melissa will produce near-historic amounts of rainfall and flooding for Jamaica, Hispanola, and eastern Cuba when it makes landfall as a major #hurricane.

[Dr. Robert Rohde @RARohde]

Hail is very non-uniformly distributed around the world.

For much of the world, you almost never see hail large enough to damage solar panels. The central USA does have some issues though.

Google DeepMind has been extremely impressive this year - these stats are consistent with what I've seen in some individual storm analyses. A few thoughts:
1) Beating NHC for track is quite impressive. AI could be a major tool to help track forecasts keep improving.
2) Given a lot of the AI intensity is basically bias correction, I expected it to be similar to SHIPS/LGEM. But it's actually much better and competitive with HAFS already.
3) We still probably need better, high-resolution training datasets to take these models to the next level.
