   Made the isolated dry thunderstorm area slightly smaller. This was
   due to decreasing confidence about storm coverage. However, there
   will likely be at least a few storms with a threat for lightning
   ignitions, which warrants keeping most of the isoDryT area.

   ...Synopsis...
   On Wednesday, a closed upper-low is forecast to persist over eastern
   Canada while high pressure builds over the western CONUS. Meanwhile,
   a compact shortwave trough is forecast to approach the northern
   California coast from the southwest by evening, as it moves around
   the periphery of high pressure.

   ...Oregon...
   The timing of the aforementioned shortwave trough appears a bit late
   to help initiate more widespread thunderstorm development across
   northern California and Oregon.  Nevertheless, isolated thunderstorm
   development appears possible across Oregon, as daytime
   heating/mixing should erode much of the convective inhibition. 
   Given that thunderstorm development will occur within a well-mixed
   boundary characterized by surface RH values <20% and PW values
   <0.75", isolated dry thunderstorms will be possible.
