.DISCUSSION...Weakening thunderstorms have been moving across
northwest Montana early this morning. Heavy rain and diminishing,
albeit still present, lightning are the main threats with any
storms still hanging on come sunrise. Given the widespread
rainfall that occured yesterday, many valleys will wake up to
patchy fog, which could be more dense near rivers and in
particularly moist areas where rainfall was more plentiful. Fog
should burn off and lift by later this morning.

At the risk of sounding like a broken record, the pattern will
continue in this manner for the next several days. Mostly benign
mornings will be followed by afternoon and evening thunderstorms,
with the pattern continuing through at least Tuesday of next week.
Temperatures will be seasonable to slightly above normal with very
mild overnight lows.

A more organized cold front looks to sweep through the Northern
Rockies around Wednesday/Thursday of next week, which could be
the catalyst to a change in the pattern for the end of the week
into next weekend. We`ll have to see if this trend changes in the
coming days, but for now, the forecast seems drier and warmer by
Friday (June 16).


.AVIATION...Showers will continue through late this morning across
northwest Montana, possibly impacting KGPI through 10/1600Z.
Thundestorms are once again expected to redevelop after 10/1800Z
and persist through at least 11/0400Z, with the potential of
impacting all area terminals with a combination of heavy rain,
lightning, and gusty outflow winds during this time.
