CAPE

I haven't done my Jan trip/snow chase to Rehoboth in awhile. Pretty scene there. https://www.visitdebeaches.com/live-webcams/rehoboth-beach-boardwalk-webcam/

The reason we couldn't is partly because of the massive vortex- our would be 50-50 low that was displaced SW of that position. The other part was the flow between the ridge out west and the TPV contributing to a lot of NS shortwaves feeding into the vortex. Even though it's weak, in a Nina the Polar jet tends to be busier and the STJ less prominent, so that's another contributing factor. As for blocking going forward, the ens runs were depicting a Scandi ridge retrograding into the NAO space, but have backed off on recent cycles. There are still hints, so we shall see on that possibility.

It does. Nice look at the surface. Getting significant HP to the north has been nearly impossible in our current pattern.

Getting breezy and it looks like its snowing with huge snowflakes as the snow comes out of the trees. Pretty cool.

This fits the trailing wave idea.

Refreshed snow scene. There is a pond there with the waterfall shrouded in ice and snow. Still a snow depth of 5-6 inches, with a bit more in areas with more limited sun exposure. Deep winter continues.

1/6/25: 9.3" 1/11/25: 1.2" Total: 10.5"

6z GFS gets close here but a little offshore. Any waves prior to that are strung out/suppressed.

The 0z EPS looks active between the 18th and 23rd, with potential for multiple waves. Best chance for frozen initially is to our northwest and then increases in the 21-23 window as the boundary moves southeastward. GEFS is fairly similar and gets cold air in place a bit sooner.

Reviewing the radar loop it looks like a few nice bands moved through here but also plenty of pixie dust.

1.2" here. I didn't stay up for any of it lol. I needed sleep. Was hoping to be pleasantly surprised but pretty much as expected.

Last few runs of the HRRR looking solid for much of the area.

The low flow dripping faucets need to be fixed. I can barely shower anymore.

The timing of the amplification and the orientation of the EPO ridge is key to getting the trough eastward sooner this run. Trough doesnt initially dig as far west. Boundary further east for the 20th potential.

28 My snowpack could use a refresh. Want some snow back on the trees for my hike tomorrow.

This is a pretty straightforward, general 1-2 deal for our region. Some places probably get less than 1 and some a bit more than 2. Southern MD/Lower Eastern shore/S DE best chance of approaching 3. Bob Chill is getting pummeled. 5-6". I'm never hyperbolic.

I like the following wave idea, given the way the pattern looks to evolve. Mentioned this in my post this morning. Based on current guidance the thermal boundary most likely will be to our NW for the threat around the 20th.

12z 3km NAM juiced up a bit

Americano, extra espresso shot with a choco edible. Oh yeah.

or coffee

12z HRRR eta- still snowing in eastern areas

This wasn't forecast to be some brutally cold airmass. Maybe 10 days out some op runs advertised Barney cold. Forecast high temps for here this week were upper 20s/low 30s, with lows in upper teens/low 20s. Exactly what transpired.

Yep western parts of the region got under the influence of HP that briefly shifted eastward, and will retreat today as our little storm moves in.

Again, the lows would have been lower if we could have managed to get HP overhead with calm winds and clear skies. The main culprit is the massive vortex locked in to the NE. Too much wind. Most days this week have had highs in the upper 20s here. Had a 31 Wed I think. No doubt in my mind there would have been some lows in the 8-12 range here with the snow cover and better radiational cooling conditions.
