This is for the wave/storm in the HR 90-102 range. I figured we are close enough to the time period for a thread. We could make a new one for the later time period (3/2 to 3/4) if the model runs hold.
Yeah, tbh it's not far off from the GFS through HR 144. GFS had .6 to -.7 QPF. GGEM at HR 144 has .5 to .6 or so. And with good ratios that should still be a very nice snowfall.
12z GGEM HR 108: http://weather.gc.ca/data/model_forecast/235_100.gif 00z GGEM HR 96 http://weather.gc.ca/data/model_forecast/134_100.gif You can clearly see what the trend is as we get closer. Look at the difference in the HP.
GGEM with .60 QPF in IA for the wave on the 28th as 16 mm= 0.62 qpf or so. That would be 8+ with ratios. http://weather.gc.ca/data/model_forecast/134_100.gif
I don't mind people who want warmer weather but like every post is talking about how things are going to trend warmer etc all based on what he wants and not what the models are showing.
18z GFS ensembles are a mix bag as one would expect 150+ hours out. Out of the 12 members: 4 have 1.00+ QPF for Chicago. 4 have .1-.25 QPF for Chicago. 4 have .25-.5 QPF for Chicago. This is a big increase over the 6z and 12z GFS ensembles though.
12+ for Chicago by HR 189. Big thing is we need to get that system to phase and lift farther north. The one for the Feb 28th timeframe. If we can get that and delay the high coming in a bit it could allow the next system to follow the same type of path. 18z GFS shows just that. We'll see if the 0z can continue the trend or if its just a blip in the 18z run.
Yup. 18z GFS showing less suppression this time around. Maybe it can move a tad north just a bit to help us out? 18-24 for W/C IA. 6-8 up towards DBQ towards Chicago (with 12+ not far off) and then 2-4 for most of C/S. WI. Just need a tad less suppression and a bit more phasing to help us out. 100+ hours out yet.
