.DISCUSSION...High pressure will continue to build into Utah
today. This will maintain very warm and mostly dry conditions at
the burn site. Humidities will bottom out near 10% this afternoon
with poor overnight recovery. Despite the dry airmass, cannot rule
out some cumulus buildups and weak, isolated, high-based showers
this afternoon. Midlevel moisture will increase a bit for
tomorrow and linger into late week, resulting in a slightly
greater chance of diurnal high-based showers and thunderstorms.
These would produce little to no rainfall but may result in brief
and isolated gusty outflow winds and isolated dry lightning.
Outside of showers and thunderstorms, winds will remain relatively
light today and tomorrow, with some gusts to around 20 mph near
ridgelines. Winds look to increase for Tuesday which could result
in marginal critical fire weather conditions.
