12Z Euro is way South like the UKMET. Always hard to beat the Euro/UKMET combo. Will definitely be interesting to see how this one turns out.
 
OTD in 1932 following what is still the warmest winter on record in most of the SE US, Ohio/TN Valley, and Mid-Atlantic, the 2nd of 3 storms produced snowfall in central NC. RDU observed snow on 3 separate occasions in March 1932, 2 of those times resulted in accumulating snow. The ground temps were undoubtedly an issue in these cases especially following a winter like that.

Anyone Have the 12z euro maps? My subscription ran out yesterday but I may need to re up if things continue to trend better. I'm sitting at 39 degrees as of 1:50 pm. Also got some Fluries around midnight last night and woke up to a minor dusting that quickly melted after sunrise.

The 12z Euro suite followed suit of other NWP models and has squashed our storm well to the south, may not be bad news as long as it doesn't become suppressed any further for south-central VA and NC but mid-Atlantic weenies will likely commence their canonical cliff jumping

If you're not a fan of severe weather, it's certainly not good to see this going into the meat of the severe season. Extreme-exceptional drought over the southwestern US and south-central high plains immediately adjacent to above-well above normal precipitation in the mid MS Valley will almost certainly provide a huge boost to the elevated mixed layer (mid-level capping inversion) & will increase potential instability. The Gulf of Mexico is also proverbially on fire which further solidifies low-level thermal and moisture advection underneath this presumed stronger EML & will boost CAPE (convective available potential energy) to go along w/ what would be more CIN (convective inhibition) if the capping inversion is more intense. This is a rare large-scale recipe that can support a huge tornado outbreak somewhere in the south-central plains, Dixie Alley, and the rest of the SE US thru April if the opportunity presents itself. We have a few priming ingredients at our disposal that are rarely observed in this part of the world and all that's missing is a triggering mechanism.
