![]() soil temperature and humidity, soil cover and vegetation, local windblown accumulations, whether there was snow on the ground already, etc.Īll these factors, besides the strictly meteorological ones, have great influence on the snow accumulation on one's own doorstep. However, these methods do not take into account some surface characteristics that will also influence how deep the snow accumulation will be. I wonder though, would this American method, taken from the heart of a big landmass, apply equally in our climate? ![]() To get the amount of snow, you would multiply the calculated amount of precipitation with the derived ratio. View NAM weather model forecast map image for Kuchera Ratio in Continental US on. Tmax is taken from the lowest 500mb above the surface and is entered in Kelvin. Less or equal to -2c: Kuchera Ratio = 12 + (271.16 - Tmax) Greater than -2c: Kuchera Ratio = 12 + 2(271.16 - Tmax) Our purpose is to keep the Gulf Coast Hurricane Center informed and safe during each hurricane season and. One for Tmax over -2 celsius (+/-) and one for under -22c. Gulf Coast Storm Tracker, Hattiesburg, Mississippi. The Kuchera Method has separate formulas to calculate the ratio. The rate of ratio change then drops off into 10s F as the way snow pellets are formed at those temperature means there is less aeration. Once temps reach the mid 20s F, ratios of 1:15+ are possible given less drifting. stay safe and get your sledge bought before they all sell out!!! that flies in opposition of other mainstream sources. To my mind the GFS seems to make a poor job of creating a coherent forecast. BBC weather seems to be following more or less the ECMS tracking. they have already sent snaps to us off vast mounts of snow over 7-8 days already.īelow, both models are agreeing to wintry weather by Saturday the 6th February. Spare a thought for Amanda Owen and Clive at the Yorkshire farm afar at Ravenseat, where most of my relations live not far on the high town called "Richmond", off scotch corner,M1 A1. I will still need to see it in Lancashire to believe snow will fall, But Im more hopeful than a few days ago, But honestly this will possible cripple the covid vaccine turnout, if towns and citys get heavy snow, along with stranded vehicles and other problems. GFS has it sinking south, while ECM has it steady increasing the chance of blizzards almost anywhere as mean winds are associated with is up to 27mph. Theres also a huge low pressure system 952mb with very tight icobars off the Atlantic. So here are the two maps from ECM and GFS for one day this weekend. see more about saving your garden birds at the RSPB site!!! The small birds remain to be feeding heavily in our gardens, and will totally rely on us to keep them alive through this 10 day freeze. Where the freeze will be tempered some what by the mini climate that surrounds North West Britain. I dont have to tell you what heading they were on do I.?.yep WEST out to the coasts of Blackpool or Liverpool or even Ireland. ![]() This morning at 8am, I saw what looked like a scene out of "The Day After Tomorrow", many flocks or skeins of birds were filling the sky at around 1000 feet. I recently noticed a good comment from an animal lover and bird enthusiast about noting nature pointers, which mainly are actually more certain than computers. Both models have been very far apart recently but todays Windys shows not a lot of difference for Saturday this week. The page will refresh upon selecting a new season.Finally both ECM and GFS seem to be on same page as todays longer range forecast from Susan Powell from the BBC earlier today.
