...More Hot and very dry conditions into July 4...

.DISCUSSION...A drier air mass is returning to the Northern
Rockies. The exception is southern Lemhi County and possibly along
the Continental Divide into early this evening where a few showers
or thunderstorm is possible.

Overall, a rather hot and dry air mass will continue over the
Northern Rockies from Orofino and Grangeville eastward across
western Montana through the 4th of July. Temperatures have dropped
a little from the extreme heat of the weekend, but again will
slowly creep upward through the end of the week. Record highs are
again possible in Butte, Missoula and Kalispell Friday.

Afternoon west winds each day will further dry the region. In fact
by late Friday and Saturday, breezy conditions may develop with
some impact to area lakes and possible fire severity.

The next threat of showers or thunderstorms may not be until early
next week. However, there is a split between the guidance..some
showing the heat and dry continuing and other guidance showing a
return to scattered thunderstorms. In any case, confidence is
rather low past Sunday. The threat of precipitation remains low
given the overall pattern may not change much.


.AVIATION...Some moisture and instability will linger over mainly
southern Lemhi County and along the Continental Divide of western
Montana. This may translate into isolated showers or thunderstorms
until early this evening, then clearing skies as a drier/more
stable air mass returns.
