Is this what you are looking for?
Does anybody have a good temp and dew point map for Tuesday?

Perfect. Thank you.

Do the temps not seem a little cool for a severe weather outbreak north of about Bham. Looks like it will be about 70 in HSV, or is that underdone?

If the NAM and GFS were right about having temps as cool as they have them overnight with every other time they have them during a severe weather threat, there would never be any tornadoes in history past 5:00pm. That's all I will say...

MOS/MEX guidance has highs of 74-78 for HSV and MSL Monday afternoon. Those are often much closer to reality in situations like this than the map-based operational models that always magically decouple the boundary layer right at sunset because of their parameterization schemes relation to solar radiation and such.

Just now noticed. Wow... think I have never seen that on day 3. Correct me if I’m wrong

We've seen up to Moderate Risks on the Day 3 more than a few times over the years, including over your specific area....

Can't say I'm particularly impressed with the 12z NAM. The evolution of the shortwave kicking NE and leaving behind rising heights is too reminiscent of 12/23/15. Overall, the evolution is very similar to that event in my opinion. Granted, that was still a localized significant event, but spatially, that it was a bust.

I am NOT saying that about this situation. I'm just comparing the overall evolution of the 500mb trough.

It also had a horrible handle on the sfc low. I think it's a bad run. The 3km NAM also limits the threat to South AL? Very odd.
