miamarsden8 Posted February 15, 2021 Share Posted February 15, 2021 After the kuchera euro, if we are to trust they fixed the bug, 12 inches is possible in Cincy. I am terrified of another NW shift though, it's getting too close to those lower amounts for me. Link to comment Share on other sites More sharing options...
RCNYILWX Posted February 15, 2021 Share Posted February 15, 2021 New thread same stormMy response to your WxBell Kuchera issue response lol: Oh yeah agree, maybe they liked the publicity with those going viral on Twitter? Was probably a begrudging change made more urgent because Pivotal came out with Kuchera maps for the Euro.

Would be nice to get that QPF with a good clipper. Hope it pans out or even over achieves, tomorrows high is only 6 degrees coming off an overnight low forecast at -1. Not sure what to think with the surface low so far from the cold sector, I'd take improved ratios over more QPF any day, easier to shovel and disappears quicker when it does warm back up.

It's expected to start in 5 hours. We are really entering the nowcast portion of the event. Time to start watching the pressure falls and where things establish and move.

Always, when in relation to QPF amount. typical snowfall at 10:1 gives 10 inches of snow to 1 inch of precipitation. Get that to 20:1 ratios and you're looking at 20 inches of snow from the same precipitation. Last snow here we had 50:1 ratios, which would equate to 50 inches of snow per the same QPF. Way different thermal profiles here though, but should be in the 12:1 to 20:1 for most with exceptions for a few. Link to comment Share on other sites More sharing options...

So if that's the case, I'd argue Cincys total is probably closer to 12 than the forecast 6-9. My call of 6-10 might be lower that it should be.

Probably should not assume 20:1 ratios there, it's all about the thermal profiles throughout the atmosphere amongst other things I am not qualified to speak for.

Because at 15:1 even that's absurd. Link to comment Share on other sites More sharing options...

I wish I could answer that with an educated response, but I cannot and will not try to. Probably should not have earlier, but I'm drinking myself to sleep tonight and felt pretty smart Hopefully it produces for you regardless, enjoy it and treat it like the last is all I can suggest.

This is the part of the discussion that Jim mentioned earlier from CLE: Source: https://forecast.weather.gov/product.php?site=cle&issuedby=CLE&product=AFD .NEAR TERM /THROUGH MONDAY NIGHT/... The big weather story for the near term period is the significant Winter Storm developing across the south central CONUS and Gulf Coast region. This Winter Storm will bring heavy snowfall and big travel impacts Monday into Tuesday. Quiet weather is expected for this evening. Below-normal low temperatures eventually reach the lower and middle teens overnight. High and mid level clouds and moisture will increase this evening ahead of the initial mid level wave of energy in the broader southwest flow aloft. Forecast confidence is high along with good agreement in model guidance of widespread light snow developing southwest of our region tonight. Isentropic lift will allow snow to gradually overspread our CWA from the south and west after midnight tonight. We are expecting this quick hitter of primarily light snow to impact the Monday morning commute. Bursts of moderate snow should occur as moderately- strong ascent manages to be maximized in a cloudy DGZ at times. Fresh snowfall by midday Monday is expected to reach 1 to 3 inches. That system will be out of the region by midday and will be followed by lingering light snow through the afternoon as weak isentropic lift occurs and some slight lake-enhancement of snow happens generally south and especially southwest of Lake Erie. Additional snow accumulations should be less than one inch Monday afternoon. Daytime highs should range from the upper teens in the far west to the mid 20`s in the far east. There have been some changes and adjustments for the main winter storm system impacting the region Monday evening through Tuesday morning. Guidance has shifted the track northwest along with higher QPF and available moisture. Forecast models have also shown a slightly stronger system and a very favorable track to bring heavy snowfall to our area Monday night. The Monday evening travel commute may be highly impacted and challenging as the snow quickly ramps up. We are highlighting the 5 pm to 5 am time frame as the worse conditions and the heaviest snowfall rates. We may see a decent deformation zone develop tomorrow evening as this system gets fully developed and bands of heavy snow with rates 1 to 2 inches per hour potentially. The other wild card will be the increasing northeasterly low level flow and surface winds tomorrow night coming across the long fetch of Lake Erie. We may see some lake enhancement of heavier snow as well near the lakeshore areas from the Cleveland metro area to the Toledo area. Our overall snowfall forecast totals are widespread 8 to 12 inches with lower amounts closer to east central Ohio and the higher amounts further northwest and lakeshore areas. There is some potential for pockets of higher amounts over 12 inches especially if we have some lake enhancements or true lake effect snow showers as this system pulls away Tuesday morning. 1 Link to comment Share on other sites More sharing options...
