Pattern Muddy March 2021

What a beautiful day today in the SE with temps of mainly high 40s to mid 60s, sunny skies, breezy N winds, and dewpoints way down in the teens to low 30s! Enjoy!
 
that first possible severe threat looks more confined to the gulf coast, given the deep vortex to our NE BECD4D4F-F30C-4D2C-B7BD-BD600734CD58.png9B06380F-C770-4E75-8EE5-149427AAFF26.png
 
Still warm or normal for much of the SE

The map is warmer in the SE largely because 3/14-20 is progged to be a transition period with warmth hanging on early in the SE. Later we'll have to see if the SE ridge ends up holding the cold back from especially the deeper SE. I'm hoping the MJO turns out to be the deciding factor and it won't. So, we'll see. I'm thankful models aren't anywhere near all knowing because otherwise there'd be no reason to have forecasting discussions like this.
 
I will rejoice in the fact that the averages are higher and below average is still mild ! So boom .
Yep, and that’s probably gonna be the last “legit cold” and that’s probably like upper 40s/low 50s and low 30s/mid to upper 20s at the coldest, but it could easily change to warmer, either way a cool shot in late March isn’t bad anymore, and we’re warming up quickly average wise, it’s just climobro !!!
 
What a great day! We don't see a RH as low as 18% very often but we have it thanks to the 18 dewpoint, which is even lower than what was progged..so look out below tonight when the winds lighten!

It doesn't get much better than this here in early March for outdoor activities from my perspective. I love the ~32 degree drop progged from today's highs, thanks to the 18% RH! The high teen dewpoints are about 10 colder than what the GFS progged:

Hold the normal to below stuff through easter weekend then all the spring. By that point it's hard for us to frost/ freeze
 
Sucks each time we ridge something wants to cutoff and N/S stuff wants to dive SE
Anyways quite a impressive ridge on the v16 66575145-3F9E-45E5-8A95-FFFE717A4461.png1E9D3640-EBAF-4567-9DB6-34726E00BFF0.png
 
I’d rather the cold signal get held back a bit more to late March, cool days in late March/early April are pretty good, problem is we switch to summer after that lol with nothing in between (which I don’t mind but some do)
 
I've for a long time been a big radiation fan and my time walking around dusk in Hogtown on good rad. nights intensified my appreciation of it further. You want to see some first class radiation? Feast your eyes on this at Augusta:

6 PM AUGUSTA-BUSH CLEAR 57 17 21 NW6
7 PM AUGUSTA-BUSH CLEAR 47 25 42 CALM
8 PM AUGUSTA-BUSH CLEAR 41 29 62 SW5

16 degree drop in 2 hours thanks to a 21% RH at the start!

Also, note how much the dewpoint rose, which is common in these radiational situations during the evening.

Glenn Burns in Atlanta talking about a big cool down coming in after the warm up next week... he also mentioned moisture... not that this has worked out this year... and he’s probably wrong.. but what the heck?‍♀️

I’m hoping for another cooldown (at least as good as the current one) to make it to the SE after the warmup due to the favorable Pacific factors of -EPO/-WPO/MJO (despite no -AO, -NAO, or +PNA bring progged on GEFS). But to even just hint at possible wintry precip in ATL from this seems a bit overdone as of now at least from what I’ve seen on model consensus and considering it would be during the last half of March. I’m not saying it is anywhere near impossible as it has happened well into April, but it becomes pretty rare once past the midpoint of the month.
 
If we do see anything wintry I needs to happen at night. I wouldn’t entirely rule out something just the chances are slim. The models have pulled everyone in all year just to let us down. So of course the models will do it one last time.

The models just aren’t “smart” enough to really know far in advance what really is going to happen. So, they do a lot of psyching as a result. The secret to avoid the letdowns is to just not believe them more than a few days out since they’re so bad. But as I’ve said, them being bad actually makes the forecasting challenge so much more interesting.
 
Looks like the GFS finally got a idea with the northern stream energy, it’s been holding it to far north while the v16 has agreed with other models, it’s clear the v16 is better 4F4EF08A-5243-4E07-82A3-DEC85524880C.pngA571206A-4963-4E0F-AE92-53778866D064.png
