.DISCUSSION...Moisture will begin to trend upward today and peak 
in the mid to late week period. This will lead to mainly terrain
based storms with gusty outflow winds over the next several days
before we transition to more widespread storms with better 
chances of wetting rainfall. Temperatures will relate to this
pattern...staying above normal into early next week before 
cooling down with the added cloud cover and precipitation.

OR THUNDERSTORMS...
