.DISCUSSION...
Localized critical fire weather conditions will setup again today
across the Four Corners region thanks to gusty surface winds and 
dry conditions remaining in place. For the weekend, well above 
normal temperatures move in and persist through early next week as
high pressure moves overhead. Generally light winds are expected 
under the high so while it will be very hot and dry, critical fire
weather conditions are not expected. Some moisture will get 
entrained into the area Tuesday and beyond bringing some relief to
highs and increasing chances for showers and storms.
