.KEY MESSAGES...

 - Higher terrain snow will continue in Southwest Montana through

   Central, and North-Central Montana, decreasing tonight before
   dissipating early tomorrow morning.

 - Daily chances for showers and thunderstorms throughout the rest
   of the week.

.DISCUSSION...

 - Meteorological Overview:

A large upper level trough with multiple embedded upper level
lows will continue to create impactful weather across the CWA
today. Northerly to northeasterly winds through the lower to mid-
levels will combine with forcing from the troughing across the
region to result in continued widespread precipitation today. This
stratiform rain will persist through tonight into early tomorrow
morning. Mountain snow will continue in Southwest Montana through
late this morning. Precipitation amounts look greatest near
Glacier NP, where northerly to northeasterly mid- level will be
most orthogonal to terrain. Those with interests in and near
Glacier NP should be aware of the risk for rockfall and creek and
stream rises through tomorrow morning.

The upper level trough moves out of the CWA tomorrow, ending the
persistent stratiform rain. However, there will be daily chances
for showers and thunderstorms throughout the rest of the week, as
instability in the atmosphere persists. Despite this, shear
remains low at this time, inhibiting the development of severe
thunderstorms. Temperatures will have a warming trend, peaking
early next week with highs in the mid to high 80s with the
building of an upper level ridge. - AM and Dzomba

.AVIATION...
29/00Z TAF Period

Wet and breezy conditions are found across North Central Montana
terminals (KGTF, KLWT, KHVR, KCTB) this evening as a band of
heavier wind and rain pivot through the area from the north.
Expect MVFR to IFR conditions to prevail through much of the
overnight across the plains as precipitation moves through and
ceilings lower. SW MT terminals (KBZN, KWYS, KEKS, KHLN) will
generally remain MVFR this evening, but some IFR conditions due to
lower ceilings will arrive overnight tonight. Precipitation
remains fairly persistent across SW MT after 12z, but becomes more
showery across the plains allowing for some opportunities for VFR
conditions. Ludwig

.HYDROLOGY...
Periods of rain will continue to affect the CWA from today
through Monday. Widespread rainfall amounts of 1 to 3 inches are
still expected by Monday.

In the Glacier Park region, rainfall is expected to be a bit
heavier, possibly up to 4 inches. Additionally, with some high
elevation snow still left, the combination of rainfall/snowmelt
could lead to some flooding on the east side of Glacier National
Park. Thus a flood watch has been issued for this region starting
on Sunday. Should later forecast today decrease the projected
rainfall amounts, the flood watch might be cancelled.

Additional flood statement might be needed if rainfall amounts
start to exceed 3 inches elsewhere across the CWA. Brusda
