BTRWx's Thanks Giving Posted February 20, 2019 Share Posted February 20, 2019 MyFoxDC's Mike Thomas pointed out that soundings are looking better than some of the model depicted precip-types fwiw. You can confirm it on PivitolWeather. Link to comment Share on other sites More sharing options...

Seems reasonable given where we’ve been the last 48 hours. Do they still use their boom and bust scenarios that allow them to cover every outcome and never bust? 1 1 Link to comment Share on other sites More sharing options...

Yeah, it’s a pretty brutal way to go about it. They should really just make a forecast. 3 Link to comment Share on other sites More sharing options...

WesternFringe Posted February 20, 2019 Share Posted February 20, 2019 In my experience here in the Shenandoah Valley, the HRRR does poorly until the moisture has cleared the Alleghenies. It's almost as if it can't decide how much will make it over, but since it runs every hour it starts to show better results once it samples how much precip actually did make it over. * *Official Weenie Handbook Rule #3241 1 Link to comment Share on other sites More sharing options...

Yep, they give me a 50% chance of 2-4”, 25% chance of less than 2”, and 25% chance of up to 7”. Way to go out on a limb and actually make a forecast. 1 3 Link to comment Share on other sites More sharing options...

It's called probabilistic forecasting. And if they fall outside their core ranges, they'll grade themselves lower. 2 Link to comment Share on other sites More sharing options...

Random Chaos Posted February 20, 2019 Share Posted February 20, 2019 I just took some surface readings of the Chesapeake Bay with my IR temperature gun - not the most accurate, but gives a good idea: 26-27F. Ground is still a bit mushy (not frozen) but the grass is getting very cold too - sub-25F everywhere I checked. Even though the air temperature is still reading 36.4F. I don't know how well calibrated the temperature gun is, but I've used it before and it seemed pretty accurate in warmer weather. 2 Link to comment Share on other sites More sharing options...

Bob Chill Posted February 20, 2019 Share Posted February 20, 2019 Sub freezing at 31 now. Nice to have a multi hour stretch sub freezing before onset. Can make a big difference if rates are light at the beginning. Also, stop looking at the hrrr until precip is overhead or at least close. It uses radar data at initialization and generally does really bad or is very inconsistent when onset is still a number of hours away. Honestly, I've never found the hrrr that useful with winter storms. Globals do far better in general. 10 2 Link to comment Share on other sites More sharing options...
