Rainshadow6.6 10,569 Posted March 27 Author Report Share Posted March 27 Well the new GFS should be sending the GEFS flowers, both events since its implementation the GEFS saved it from a last place finish. The UKMET with the driest solution came in 1st. The next event the Ukie looks destined for either a 1st or last place finish. Quote Link to post Share on other sites

Rainshadow6.6 10,569 Posted March 29 Author Report Share Posted March 29 Well, a very good event for the new GFS. Much more consistency in the sounding runs (which started too dry) for the two previous events. Given there were convective elements with this one, maybe this one could be better than the previous GFS which was often too dry in scenarios like this. As suspected, the UKMET with its superfluous qpf thudded into last place. A wet bias model standing alone is not a very comfortable position to be. Quote Link to post Share on other sites

Rainshadow6.6 10,569 Posted April 1 Author Report Share Posted April 1 Come early May we will do the big look back and see how the models did as far as second place. This was really the cool season for the EPS which unless I am forgetting many events should come in first place. The race for second and for last will be interesting. Off the top of my head, neither the GGEM or UKMET have been gee whiz models this season either. Case in point with this event where they were too bullish on the warm conveyor belt precipitation early and (over)corrected too late. The OP EC was too west also, but was more accurate (or less extreme). A criticism I have read about the new GFS has been its more run to run inconsistency, even though with this event, the PHL predicted pcpn amounts were pretty steady, albeit too light. It ended with a solid second place finish. In the end it was the EPS that came in 1st and the UKMET will need a rescue boat event it was predicting to try to motor its way out of another last place finish with the next event. Just before go time for the EC & GFS: Quote Link to post Share on other sites

I don't know how many previous versions of the ECMWF you can grab, but I will match you with the other models. 12z yesterday, the 3rd would be as far back as we need to go. Yes and also start Wednesday with the 12z run today. Quote Link to post Share on other sites

Tricky as to a last run, but the ones that have measurable have it getting in before 12z or shortly thereafter. I will let you know about the next one, we will be busy.

Rainshadow6.6 10,569 Posted April 7 Author Report Share Posted April 7 UKMET was not available for every sounding run and not evaluated. Disappointing poor performance for the new GFS. Yeah the WEFy WEFS saved it from a last place finish again. You don't have the GGEM & ECMWF on board with measurable pcpn (they tied for 1st), you are in trouble. Like tomorrow's possible event, this was a triple conundrum to resolve as the band of predicted precip was narrow. First would the precip survive from the Great Lakes. Second, if it did, where would it go and how much would fall. Can't even give the GFS credit on a misplaced event as Wilmington traced out and the highest measurable in the entire state of Delaware was 0.03" in Blackbird. Quote Link to post Share on other sites

Rainshadow6.6 10,569 Posted April 7 Author Report Share Posted April 7 @tombo82685, I just looked at the 12z Euro. Scratch that remark. The EPS crosses the threshold. So, with the 12z run today let's go thru 00z/Sunday 8pm/Saturday with that warm frontal pcpn shot and then separate the next event on Sunday(?). Quote Link to post Share on other sites

Rainshadow6.6 10,569 Posted April 8 Author Report Share Posted April 8 Like Tueday's "event" yesterday was a triple conundrum to resolve. The band of predicted precip was not as narrow as the modeling depicted. First would the precip survive from the Great Lakes (yes it did). Second, if it did, where would it go (more north of PHL) and how much would fall (generally too much predicted throughout PA, ok for parts of central NJ). As it resolved, the GFS/GEFS came in tied for first and the GGEM which placed the heaviest precip band over PHL (before shifting it correctly farther north) came in last. We did miss one UKMET forecast in this sequence because of data transmission issues. It would not have come in first, might have come in last. The "big four" climate sites had either a trace or 0.01". Quote Link to post Share on other sites
