.DISCUSSION...High pressure will remain over western Montana and
central Idaho through the rest of the work week. A steady trend
towards warmer temperatures is expected, with Thursday likely
being the warmest day of the week. In fact, many valley locations
are expected to reach near 60 degrees by Thursday afternoon. Lots
of sunshine is anticipated through this period, though a slight
increase in clouds is possible Thursday afternoon into Friday as a
low pressure system passes to the south. Low elevation snow will
continue to melt under the warm afternoon temperatures, though
cool overnights should keep the melt from becoming a problem.

Forecast models continue to show a system moving through the ridge
over the weekend, which will bring precipitation to the region. It
should remain warm enough that valleys remain rain and mountains
see snow. Models differ in terms of the amount of moisture
that will occur however. This will have to be watched in coming
days as rainfall could further increase low level snowmelt and run
off. Another possibility is to see the first isolated lightning
strikes of the season.

.AVIATION...VFR conditions will continue across western Montana
and central Idaho with generally clear skies and light winds.
Patchy fog will be possible once again Tuesday morning, primarily
across northwest Montana and in the vicinity of KGPI.
