Zooming in on that map, I can sortof see where stemwinder would be north of that path.  Still too close!!!

And the 6z GFS has a coastal thing for that March 4 - 5 frozen.

Ens means don't like the early March threat. Means have the low passing N and W with redevelopment too late/far N. Likely looking at a thump to something sort of deal if the looks at HL hold. Pretty certain the HECS depicted on yesterday's 12z gfs was a one and done blip. Still signals across the means going thru mid March that we aren't done tracking and the weeklies keep hope alive thru early April. Pretty much playing out as expected...backloaded if we are going to score with a delay in spring arriving. Never a doubt lol.

Wow,  I think maybe the warm front is on the move and although the temp here hasn't gone up yet, the fog has rolled in like mad from the north.  Vis down to about 1/10th of a mile.

I ended up with a high of 44 and 0.02" of precip yesterday despite all the stuff that blew overhead.

Currently a damp and foggy 40 after a low of 39 and with dp 40.

If the 6z NAM is right about temps today, then ChescoWx and Kamu might see mid-60s to near 70 while Redsky and Birds69 don't get out of the upper 40s

Forecast was for the front to finally pop up and off the mountains by the early afternoon.

Currently still in the 30s/40s in the CWA.

I lived right where this hit about 6 years ago. Went right over my old condo. Good thing I moved!

Wow.  Small world.  I found a video someone posted showing some of the damage.

 

Adding updated PNS issued yesterday afternoon.
