.DISCUSSION...

Starting to see a few reports of precipitation making it to the
ground across the forecast area. Temperatures are below freezing
in a few locations and there have been a few reports of sleet
mixing in with the rain. With the strong warm air advection just
above the surface, expect precipitation will quickly change to
all rain and do not anticipate any impacts from the brief wintry
mix at the onset. Speed up and increased PoPs some based on the
latest radar and hi-res model trends. The 12z sounding from OHX
indicates a significant dry layer below 750mb and any
precipitation that makes it to the surface will be light.
Overall,rainfall amounts will be under a tenth of an inch for most
locations. Temperatures will struggle today under cloudy skies
with highs generally in the mid 40s.
