.DISCUSSION...
Isolated showers and storms will occur again today as we've seen 
over the past few days. Gusty outflow winds and some brief heavy 
rain will be the main concerns. An uptick in moisture over the 
weekend and beyond will allow more widespread convection to form. 
Also, increased cloud cover and precipitation will cause 
temperatures to drop to more normal values. Critical fire weather 
concerns will be minimal over the next several days.
