Historic April Snowstorm for Southwest KS? All the major model runs are still pointing to a major accumulation of heavy, wet snow beginning early tomorrow morning over extreme western KS and developing southeastward during the day. The timing of the rain/snow line is the real challenge. Per the NAM model, we may see snow here as early as 3pm or so. The NAM shows a warm layer aloft centered around 750mb that will keep us from being snow until about this time… despite 850mb temps being about -1C or so several hours earlier. Man, the Canadian model QPF is still going nuts! Check out the 3-panel I put together from this mornings run:
Estimated 12-hr QPF for Dodge City:
ending 24hr: ~10mm (.39")
36hr: ~21mm (.83")
48hr: ~17mm (.67)
Storm total: ~48mm (1.89")
