.DISCUSSION...High pressure will continue to build over the
Northern Rockies these next few days resulting in a pleasant
warming and drying trend. A few additional cumulus clouds will be
present on Tuesday afternoon as moisture begins to slowly increase
in the upper atmosphere. Some of these build ups could produce a
brief shower and perhaps an isolated lightning strike, but nearly
exclusively over the higher terrain.

Models continue to show better agreement with an increasing trend
in showers and thunderstorms between Wednesday and Thursday,
ultimately bringing better chances for more widespread
precipitation impacts to western Montana and central Idaho
valleys. But the activity each day will significantly diminish
each night with the loss of daytime heating. Temperatures will
steadily grow cooler but trend more towards normal for late
April. The forecast for next weekend is still a bit more uncertain
with forecast models sharing a fairly wide range of possibilities.
However all these solutions considered, it would appear as though
unsettled weather (persistent chances for precipitation) with near
normal temperatures may ultimately prevail. In other words, it
doesn`t look like next weekend will be nearly as nice as this one!

.AVIATION...Building high pressure across the region will make for
some nice fair weather flying. The biggest impact will be from
prescribed forest fire and agricultural burning causing smoke. The
smoke will not get thick enough to cause a reduction in flight
categories and will mainly be an inconvenience.

.MSO WATCHES/WARNINGS/ADVISORIES...
MT...None.
ID...None.
