watch out for drifting tonight.

be very careful when you disagree with him he will curse you out and start screaming at you. Wright Weather Board!!!~!

RGEM is like the NAM.

snippets from Chicago NWS Forecast attention this weekend focuses on the major winter storm expected to have significant impacts across a good chunk of the southern and eastern CONUS. Locally, our area is expected to remain along the northern periphery of this large and expansive storm system, which naturally adds question marks with regards to how far northwest impactful wintery precipitation will fall. This is especially the case considering that a sharp north- northwestern cutoff in precipitation could occur over, or near parts of northwestern IL. Nevertheless, forecast confidence continues to increase in accumulating snowfall falling across much of central into northeastern IL and northwestern IN, most notably during the Saturday night and on Sunday timeframe. While a majority of the heavy precipitation with this system is expected to fall south of our area, as mentioned, chances continue to increase that much of our local area will experience some accumulating snowfall late Saturday through Sunday. The snow may come in two separate waves, with the first potentially coming Saturday afternoon into the evening, and a second coming Saturday night and on Sunday. Interestingly, with the Arctic airmass remaining in place across our area, the thermodyamics profile in which this snow will be generated within will feature a very deep Dendritic Growth Zone (DGZ), likely in excess of 10,000 ft. This will in turn foster a higher than average liquid-to- snow ratio than is typical for our area, with 20-25+ to 1 ratios certainly in play. Accordingly, even a tenth to two tenths of an inch of QPF that falls could result in a few inches of dry fluffy accumulation. While confidence does continue to increase in at least parts of our local area experiencing some accumulating snowfall Saturday afternoon into Sunday, uncertainty remains with the specifics. For example, as noted above, one of the main question marks that remains is how far northwest into our area accumulating snow will extend. This as the precipitation looks to fight with drier air trying to advect into the region from the Arctic high to our northwest. The other question resides around the extent of lake enhanced snowfall along the south-southwesterly periphery of Lake Michigan Saturday night into Sunday. Low-level thermodynamic conditions do look favorable for this, and there is concern that this could result in higher snow amounts along and near the lakeshore into Sunday. Stay tuned for forecast updates!

going down swinging Alek with almost 9 inches enjoy!!!

It is the NAM (useless) I wonder if DocATL will check back in!!!!

Lock it in X

12z X

18z Euro backed down from 12z toss it!!!!

hopefully no Winter Weather Advisories will be issued NWS has had a tough run in here. and toss the 18z GFS

chicago NWS The next item of interest is the threat for accumulating snow sometime late Saturday into Sunday. A significant winter storm is expected to impact a large chunk of the central, southern, and eastern CONUS this weekend, and we will largely reside along and near the northern periphery of this storm. In spite of this, there continues to be signs that the expansive precipitation shield to our south may expand northward across our area sometime Saturday into Sunday. While model and ensemble guidance does continue to trend in this direction, it is important to note that considerable uncertainty continues with the specifics of this system. This is especially the case considering that some complex interactions are likely to occur with a few separate waves transitioning through the larger aggregate trough in the west. Nevertheless, if snow does end up making into our area but not for DocATL, very cold temperatures will support high ratio (20+ to 1) fluffy snow which would make for widespread hazardous travel across the area through the second half of the weekend. Stay tuned!

As soon as Doc mentioned that the Chicago folks can leave the Euro stopped

To buckeyes point

12z NAM fantasy long range nice jump north from 6Z

10pm Milwaukee update Snow is beginning to move into the region late this evening. Area of banded snow that has been discussed over prior forecasts is materializing from central Iowa east to the Wisconsin- Illinois border, with lighter and more disorganized activity apparent into west-central Wisconsin and southeast Minnesota. Banded snow is blossoming along a band of 925-700 mb frontogenesis that continues to sharpen to the northeast of a developing surface low near Omaha, NE. With most pronounced surface pressure falls apparent to the east of the low, expect that the newly-developed surface low will track over south- central Iowa and northwest Illinois through the overnight period. Already beginning to play out in radar trends, this will put our southernmost counties (particularly those near and especially south of I-94 & US-18) in line for the greatest banded snow potential through the overnight hours. Have thus maintained the ongoing Winter Weather Advisory as-is, with the expectation that the higher end of the forecasted 2 to 5 inch totals will materialize closer to the Wisconsin-Illinois border. Will continue to monitor through the overnight hours. Budget extra travel time if commuting tomorrow morning, particularly over the southern part of the area.

Not for Oklahoma and Arkansas.

eye balling 2-3 inches here worst is over

one of the better 30-45 minutes burst of snow and wind in a long time.

wait 5 minutes

why cant we get storms like this GFS fantasy storm

Enjoy

12z Euro pounds us with 2-4 inches on Saturday

technically our week of winter occurred in the fall.

looking forward to our 7 days o winter in early Feb!!!!
