When visibility is low and temp is 32-34 it will show up as freezing fog i believe

Regarding previous difference in maps discussion - I am wondering if the weatherbell map is 28km resolution since the maps I saw posted here had “gfs 0.25” and pivotal is 13km. That would be one way to explain output map differences.

I believe I had it explained to me a few years ago that they have discretion to issue warning because of the ice when forecasted to be more than a glaze.

I know I am several inches behind what others have reported in the area so this difference may be right. 4” today puts me at 20.9” for the month - I am missing some of my data so I don’t know what my season total is at the moment. I know there was at least one event (around the 10th maybe) that east shore & city had reports of an inch or two more than what I had as a heavy band just missed home to the south and east.

Yep 3k NAM is showing pretty strong push of warm air around 700mb that would really knock down totals across MD/southeast PA as sleet

Getting bigger flakes at home now but still a good bit of sleet mixed in - I only have 3.25” total so far

It at least flipped back to snow - but have been on the edge of this so far so not dumping but more moderate here

It is all about how far west the model runs are sending the upper level dynamics - the runs that are sending it west are the ones spitting out the higher numbers on the snow maps and the ones that are not look like this GFS map or the much lower HRRR solution. The upper level dry air showing up so well on current water vapor imagery already as well as the model runs worries me (as in need under banding for good snow or face dry slotting), but will have to see how things shake out tomorrow.

Wind picked up and it turned into a burst of best flakes of event for a few minutes but I’m back to sleet now on other side of the mountain

Looking at correlation coefficient imagery from the radars and mPing reports the ptype transition line is racing north and east much faster than I was expecting but with low track to our west honestly I’m not surprised... starting to wonder if more icing ends up occurring around here than was expected. Cold near surface will hold but aloft not looking likely.

Any reports of damage from around Duncannon to Halifax and just east? Radar struggles due to terrain in that area but looked like it was picking up on at least some rotation with that line that just went through.

KMDT only managed to fall to 16 overnight and that was briefly around 2 am when winds went almost calm for a little bit - as soon as the breeze picked back up temperatures climbed back to 20-21 degrees and stayed there the rest of the night. My snow took quite a hit yesterday from the sun and wind where I only have about an inch left in areas that the sun hits most of the day and about 4-5" depth in the some sun but more shaded areas.

haha that is my current running total as well - here are my records based on morning reporting times so dates may be slightly off from how others record: 11/16 - 8.0", 1/13 - 2.2", 1/18 - 1.7", 1/20 - 3.8", 1/30 - 2.4", 2/2 - 1.0", 2/11 - 1.1", 2/12 - 4.4", 2/21 - 5.0", 3/1 - 4.1", 3/2 - 3.3", 3/4 - 4.5" = 41.5"
