Was that first Euro 0?  The dot confuses me.  I am easily confused. Red bananas, yellow bananas, green bananas.

The GGEM is scorching lately.  It's 3rd first place finish in the last four events.  The OP Euro & EPS came in a flat footed tie for last.  The way this winter is going, a modeling consensus looks like it would work better.  No model or ensemble is running away with it.  On the flip side, the GFS is yet to have a 1st place finish.

Speaking of the GFS, the operational runs avoided the glue sniffing the off sounding runs did with snow for PHL.  So no snow table needed.  A tenth here, a tenth there for the ensembles.

Yeah we can go thru 12z today (25th).  Was easy.  Great job GFS with the fgen forcing said no one ever.

Well well well. One must be new here to be shocked that the GFS had the most inaccurate snowfall forecast for PHL with this event.  The GGEM which never had measurable snow from the 12z run on the 22nd (yes since Sunday) was the only model/ensemble to do so.

On the qpf side, I don't recall as much convection as this wreaking havoc with synoptic scale events.  But, here we are. The 0.96" at PHL was representative, but heavier convective induced rain fell just to the northwest.  Taking that into account as you like, the GGEM came in last and the GEFS which has not had a bad cold season came in 1st.

Better late than never.  The two precipitation events from this past week. Because the gap was less than 24 hours, I could not get the CoCoRaHs maps other than the early morning snow on the 1st.

January 31st event:

The GEFS has quietly having a decent season for it and came in 1st on the qpf side. What is more amazing the EPS came in last. Light event.  I was going to ignore the snow side because of a tenth here and there, but there was the UKWET with the (wrong) heaviest snowfall forecast of any model and it was even heavier elsewhere in Pennsylvania.

February 1st event:

On the 25th weather event of the cool season, the GFS finally came in 1st on the qpf side.  Okay tied with the ECMWF, but tied for 1st nonetheless.  It was right for the wrong reason as it (and the Euro) did not have precip with the 2nd wave until late in the ballgame.  The binary yes/no the UKMET &GGEM were more consistent and right about measuring.  Unfortunately when the GGEM is the wettest model, it has earned a last place finish. On the snow side the same fate occurred to the GGEM.  The quiet GEFS came in 1st.
