Geos Posted February 17, 2014 Report Share Posted February 17, 2014 Geos, just think it's funny that the pin points went down and then their graphic switched to area wide 4-6" Now I just saw that. Actually 2 miles down the road from me. The office downplaying this may well be the luck we need to get off the schneid of nickels and dimes. You can tell I'm somewhat superstitious. Well they got burned quite a few times going too high. Lol, that's probably the reasoning behind this forecast.

WildWisconsinWeather Posted February 17, 2014 Report Share Posted February 17, 2014 Now I just saw that. Actually 2 miles down the road from me. Well they got burned quite a few times going too high. Lol, that's probably the reasoning behind this forecast. A few times, though other times they were questioned and criticized yet got it right. New Year's Day was an example. One of my bigger qualms with them is going bullish so early with some events, and the fact that they now issue hour by hour timelines, which bust more often than not.

Tom Posted February 17, 2014 Report Share Posted February 17, 2014 Intensifying systems are always fun to watch on the radar as there is a higher probability bands wont fade away as they approach your area. Instead, they increase in intensity and maintain their strength. Quote Link to comment Share on other sites More sharing options...
Money Posted February 17, 2014 Author Report Share Posted February 17, 2014 If I were MKE/LOT I would probably upgrade the WWA to a WSW for 5-7 with isolated higher spots. Plus for the timing of the snow and how it affects the evening commute. Quote Link to comment Share on other sites More sharing options...
MarcusBeier Posted February 17, 2014 Report Share Posted February 17, 2014 Im confused with this storm, is it strengthening as it heads east or weakening? Showing higher totals the further west you go from me in SEMI suggests the latter but everyone is saying atleast some if not all models are showing some form of strengthening and lowering pressure as it moves east.

Tom Posted February 17, 2014 Report Share Posted February 17, 2014 I think the most snowfall amounts are going to be where this system starts going neg and places like IA/WI/IL/N IN are in prime spot for this happening. Folks in SE MI may not get as much bc the system looses its neg tilt as it lifts to the east. There are strong dynamics with this system and the high rez models are picking that up. We are within the 24 hour period and its time we start paying attention to the HRRR/RAP and other high rez models. Global models are good but they won't see the capacity this system may deliver. You can also see the 850's tank as this system goes neg and that will really increase snowfall accumulations tomorrow mid morning/afternoon hours. 1 Quote Link to comment Share on other sites More sharing options...

The Snowman Posted February 17, 2014 Report Share Posted February 17, 2014 Looking at 3 hour precip totals from the hires NAM, the QPF range from bare minimum to extreme maximum is 0.46" QPF to 1.10" QPF. For example, if a certain color on the map was green, and the precip range for that color was 0.25" to 0.5", the 0.25" would be bare minimum and 0.5" would be extreme maximum, since 0.25" is the least that can be in that shade of green, and 0.5" is the most. Basically, I added up those minimums and maximums for the whole snow event. 5" looking like the floor, ceiling probably around 8" at best. Good range, IMO. Definitely overperformer potential here. 1 Quote Link to comment Share on other sites More sharing options...

Tony Posted February 17, 2014 Report Share Posted February 17, 2014 With a neg tilt system many things are in play. With very high UVV's there can be intense convection so as I said before we can see lollipops of 10-12" Quote Link to comment Share on other sites More sharing options...
DominicR Posted February 17, 2014 Report Share Posted February 17, 2014 If this can over perform ORD could crack 70 out of this but not likely it will be close by tommorow night. We just need a a big one and a moderate one by late Feb/March or several more mod winter snows like this to break record. 1 Quote Link to comment Share on other sites More sharing options...
Iowawx Posted February 17, 2014 Report Share Posted February 17, 2014 Latest RAP is showing 1-2 inches per hour when the snow moves through.
