Although this is titled quick snow update, we should include the beneficial rain as well, as it will be significant.

Snow develops late tonight out west and slowly transitions eastward on Wednesday. The greater OKC metro area will see rain up until late evening when it converts over to snow. I’ve included some maps for timing and amounts. The system exists the state Thursday morning.

I mentioned heavy rainfall will occur. This is the QPF map, meaning where it’s cold enough such as W/NW OK, we have to convert this liquid to snow at around a 10:1 ratio, so 1″ of liquid would be 10″ of snow. The rest of C/E OK will see rain, so these will be our rainfall totals in these areas.
