ukie gonna be good for Hoosier

KLOT update (great writeup) https://forecast.weather.gov/product.php?site=LOT&issuedby=LOT&product=AFD&format=CI&version=1&glossary=1

I buy

i am going 4-8 with less in McHenry county

What about the GFS v16 with about 5 for you, are u not buying it?

yes but the 18z GFS doubled your snowfall and the 18z GFSV16 stayed the same so nice trends for you if u ignore the NAM

yes i am a little confused as I am under an advisory for 2-5 but my forecast is for 2-4 tomorrow and and 4-7 tomorrow night

KLOT update great read https://forecast.weather.gov/product.php?site=LOT&issuedby=LOT&product=AFD&format=CI&version=2&glossary=1

the 18z NAM moved back east (McHenry Snow is correct) and according to this model run he will bust high on his 1-2 inch prediction. The 3K NAM is slightly better.

LOL all the the same for my backyard and all show more then 1-2 inches for u. The next time u r optimistic about a storm will be your first time. Enjoy your afternoon.

Question why are they outliers when u have the GFSv16,GEM, RGEM , UKMET and both NAMS pretty much in agreement? They could all be wrong but please back up your statement.

12z HRW WRF-ARW Destroys northern cook county that small orange dot representing 30 inches of snow

NAM 54 hrs

yep its over

Enjoy ALEK

KLOT aviation update A lull in the IFR visibility reducing snow for many areas, except in NW IN and near the lake, has occurred this morning in wake of a leading band overnight into the morning hours. There is a more organized band of snow associated with a secondary upper level jet stream will lead to an uptick in snow at least for a couple of hours this afternoon across the northern IL terminals. Expect ceilings, which have increased to MVFR or even low end VFR to dip back into MVFR or a lower MVFR then currently. Vis may drop back to 3/4SM in this snow with medium-high confidence. Snow rates of 3/4" to 1" per hour may be possible in this band of dry snow.

ukie is liking the same areas

0z GFSV16 24 hr snowfall. I call challenge on the 11 inches over cook county and totals thru 2/16

KLOT The main axis of snowfall amounts in the 2-4" range has shifted a bit north, focused more around the I-80/88 corridors with this update, with amounts lowered to for our southernmost counties to an inch or less. PoP trends for Saturday morning are a bit unclear, as we`ll begin losing the better jet support, resulting in an overall weakening to the already modest mid-level f-gen. This may allow lingering light snow near/south of I-80 to dwindle, before additional ascent from an incoming shortwave pushes across our northwestern locales. Have trimmed PoPs south and east of I-57 as a result, and left the categorical/definites going elsewhere.

silly 18z NAM still thinks that the snow will reach into IL on Monday I guess the GFS hasnt informed it yet!!!
