Pattern Muddy March 2021

Crazy how some would rather it be raining in the 40s and 30s then this sort of stuff. 73F here, about to grill some barbecue drumsticks

It has been amazing all week long here, too! But there's a huge difference between 60s/70s with dewpoints in the 10s-40s (like this week. which I've loved every bit of) vs 80s-100s with dewpoints in the 60s-70s, which you have implied you love, too.

Bottom line: DS for DF! If someone likes cold rain, that's fine. If someone likes 100s with dewpoints in the 80s, that's fine too.

Fro,
I love your map, but you'll love this one, which is the average of the last 20 runs of the CFSv2. Of course, the CFS generally sucks in accuracy:

Man that looks awesome, but I’ve seemingly noticed that the climate models love to spit out the H5 pattern that’s typically seen with the state of the ENSO, for example this winter they were showing the overall La Niña pattern with a SER this winter with a trough in the PNW/AK and instead we got blockbuster blocking
 
If only the EPS was actually dry

I would be more upset if I was staring at this in early March wanting warmth but averages are rising quick, I’ll take some 50s and rain, always light at the end of the tunnel, and typically with +PNAs you get some dry days under the trough, I’ll take it honestly (in fact we’re getting to that time of year where you can start getting convection under upper level troughs)
 
Ehh, gonna have to say those plots aren't too shabby... They helped me key in on the potential for cooler weather (anomaly-wise) late in the month a week or so ago, or at least that we weren't gonna have wall-to-wall torch as some hoped for. Looks to be panning out thus far.

La Nina forcing in April gives you +PNA/cool eastern US.

Bottomless cold rain ?

Thanks, Webb! I never knew that.

So, I decided to check KATL Aprils for lingering La Nina: 1950, 1955, 1956, 1971, 1974, 1975, 1985, 1989, 1999, 2000, 2008, and 2011 and sire enough it supports your finding.

I got the following for these 12:

- 4 solidly BN
- 3 slightly BN
- 1 NN
- 1 slightly AN
- 3 solidly AN

So, some advantage for BN side over AN side (7-4) but the sample size is pretty small. I need to expand back into the 1800s and would use your tables to do so if I do it.
