WRF Showing Rotating Updraft Potential

This image shows the maximum updraft helicity. In other words, it shows the spinning of thunderstorms as they form, which could create a tornadic situation.
There is an abnormally high rate of helicity in Kentucky and Southern Indiana, which greatly worries me that the tornado risk may be a bit underestimated with instability around 1000 j/kg.

I agree about snowday. Craig does a good job with his site but the people on there are just nasty. A live chat makes sites become places where venom is exchanged. Live chats turn more away than they bring in.

My new personal favorite model, the UKMWFS is predicting 6-48 inches of snow from the OK panhandle to New England. What impresses me the most is the remarkable consistency it has had today. 10 straight runs! This storm is still 2 days off so some changes are possible. I am very confident that winter storm watches will be out tonight. Stay tuned for this particularly dangerous event.

Do you happen to have a link to the model? Thanks.

Hello ERN WX.Are you serious about this winterstorm?

ERN WX said...

Sorry, Andrew there is no UKMWFS. I made it up last year for today. Everyone else asks me to show them it so don't worry. However, a UKMET/ECMWF/GFS blend has worked well for me lately. I sincerely apologize for any confusion. Sorry, Mike, no snow.

No big snowstorms until late October. That will be for the North Plains.
