Area Forecast Discussion...UPDATED

.DISCUSSION...
The forecast generally appears to be on track, in line with the
latest obs, but some small tweaks to PoPs will be made for the
morning update. It is noted that the latest HRRR runs seem to
develop more convection in our western half this afternoon than
the weak instability and lack of moisture in the 12Z OHX sounding
might suggest. Also, model PW values at CHA this morning appear
to have verified too high compared to the 12Z soundings around the
region. PoPs in the forecast will be reduced to a slight chance
for southern sections and the Plateau this afternoon.
