DEWALDWhile that above statement shows 4-7 inches possible, most weather guidance shows 1-2 inches in the metro area should be expected. The NWS forecast (not the above warning, but the point forecast) should <1/2 inch. I'll check on the situtation further.
Regardless, it doesn't appear to be a big situation as the ground is still fairly warm. This past week we've seen temperatures at record high levels (74F), so any snowfall that should occur will melt or become slushy. The ground temperature (4" below the sfc) measured near 180th and Cornhusker Road (SW Omaha/NE Gretna) was still 48F.

SCHURRBy the way, at this point in the year, Eppley Airfield (official observation location), Offutt AFB, and Gretna have all recorded a trace of frozen precip this year (beginning on July 1st). All of the locations have picked up some hail (which counts toward snowfall totals) and the Gretna location had some ice pellets a few weeks ago.
