.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.
