.DISCUSSION...High pressure will be centered near the Four Corners

area Wednesday through Thursday. This will maintain very warm

temperatures over the burn site while midlevel moisture gradually

increases into the area. On Wednesday, cumulus buildups will be 

possible near the ridgelines, but shower activity is not expected.

By Thursday, isolated high-based showers and thunderstorms will 

be possible during the afternoon and evening with the main threat 

being briefly strong and gusty microburst winds with little to no

measurable rain expected. Outside of showers and thunderstorms, 

winds will remain relatively light Wednesday and Thursday, with 

typical terrain-driven diurnal flow directions. 



Looking ahead, as the airmass continues to moisten, shower and 

thunderstorm chances will increase into the weekend and next week,

with an increasing potential for wetting rain.
