@40/70 Benchmarknot sure hw much you're into datasets/updates but ERSSTv6 data has been released. Read through  a good bit of the paper...really interesting stuff. I know you don't do much with ENSO pre-1950 but it seems this version helps greatly with some of the uncertainty and error with SST data pre 1950.

If there are maps worse than snow maps...it's ice maps :lol: 

I would actually much rather snow maps than ice maps....ahhh I can't believe I said that. Someone put soap in my mouth 

I’m still wondering where these mid 30’s temps are coming from in seacoast NH with every piece of guidance cooked just above the surface. The GOM is broadly in the low 40’s and winds are predominantly with a significant easterly component so no answer there either.

This is a pretty complex situation. Almost looks like the wedge of cold is more focused up around 925mb and not even much wedging at the sfc. Hi-res has the coldest temperatures in the higher elevations versus within the valleys...opposite of what you would expect. Big key may be what happens with temperatures Friday night because there doesn't seem to be much room for temperatures to rise at all north of the boundary.

It’s from wetbulbing. If it were dry and sunny it would be much warmer.

Where are we at with the monthly departures at the major SNE climo sites? What is a good site for that? I had +1 to+3 F

The Daily Climate Reports I think may have that info.

EDIT:

I meant NOWdata

Here's BDL

May as well get some ZR while BDL is 80°.

Brian,  I have a question about solar insolation this time of year.  Although the models show the potential for a lot of ZR with temps around 29-30F here wouldn't solar insolation still play a big factor?  I would guess it is pretty hard to get an ice storm in the last days of March but maybe I'm wrong??

Well you know how dark and dreary it can be up here in these wedged CAD events. If the solar rad is low through dense overcast there won’t be much saving us even during the day. We had a decent icing event in April some years back too.
