hlcater Posted December 18, 2022 Report Share Posted December 18, 2022 Loving the forecast for here. Solid floor of 3-5" with gusty winds even if the big low fails to deliver this far west. However, a shot at something more if this trends just right. Regionally, if not nationally, impactful storm trending to a near certainty at this point though. 3 Quote 2021-22 Snowfall: (Hiawatha) TOTAL: 10.2" (12/28: 3.0") (12/29: 0.8") (1/1: 6.4") Link to comment Share on other sites More sharing options...

Clinton Posted December 18, 2022 Report Share Posted December 18, 2022 EAX mentioning the possibility of a Blizzard. Focus then shifts to what looks like the most significant cold outbreak since February 2021. A very strong PV anomaly will move southeast out of British Columbia into Montana and Wyoming. As this anomaly digs southeast into the Plains, its associated cold front will plow south through the region. Strong forcing ahead of the wave with a building arctic air mass moving in will lead to widespread snow developing Thursday morning. As the surface low deepens rapidly with the wave taking a negative tilt over the area, the pressure gradient tightens substantially. Strong momentum transfer with the tight pressure gradient suggest very strong winds can be expected while snowing across the area. This has the potential to be a blizzard and we`ll have to really monitor trends. If this system digs a little further west and begins its occlusion further west, it will mean the difference between a couple inches of snow with strong and gusty winds vs much higher snow amounts and much stronger winds. Regardless, with holiday travel increasing heading into the start of Christmas weekend, major impacts are likely locally and throughout the Midwest. The other major impact with this system will be the dangerous cold. Have continued to trend temperatures downward. Thursday`s high will likely be overnight, while temperatures fall throughout the day. Add in the wind and wind chill values during the day Thursday will likely fall into the -20 to -30 range by the afternoon hours. It gets worse overnight into Friday morning where lows will likely range from -5 to -15 and wind chill values in the -30 to -45 range. There is a chance highs Friday will be below zero given the air mass and likely snow cover. Forecast currently depicts zero to 5 above for the KC area with subzero highs confined to northern MO. Temperatures begin to moderate Saturday with highs in the single digits to teens forecast. Upper- level ridging begins to build into the western states Christmas Day and that may help temperatures "warm" into the teens and 20s across our forecast area. 3 Quote Link to comment Share on other sites More sharing options...

Hoosier Posted December 18, 2022 Report Share Posted December 18, 2022 A good deal of the storm is actually not that cold here on the GFS. But this will depend on how quickly the surface low moves north. The GFS forecast soundings are phenomenal from a wind perspective. Not looking at gust maps but the actual forecast soundings/mixing depths which would suggest a window of 70-75 mph gusts here on Friday. 1 1 Quote Link to comment Share on other sites More sharing options...
