Evening Update (9pm MDT): No changes to the forecast for the short
term. Expect pleasant weather to continue as expected. Bigelbach

PREVIOUS DISCUSSION: The upper ridge will move over Montana
tonight with mostly clear skies. A shortwave will push a cold
front into the region on Wednesday, and through northeast Montana
Wednesday night. Mostly expecting gusty winds with the frontal
passage but could see a few showers in the evening.

Upper ridge builds back into the Rockies and high plains for the
end of the week as storm system begins to take shape off the
northern California coast. Dry and warm conditions expected for
into the weekend.

The California system will begin moving through the Great Basin
late in the weekend bringing the potential for some rain to
eastern Montana for early next week. Still a large spread in the
model solutions so amount and type of precipitation are still
uncertain. Ebert



Expected Flight Category: VFR

Synopsis: High pressure over the region will lead to continued
pleasant flying weather. A mostly dry cold front moves through
tomorrow, presenting some possible VCSH and some LLWS concerns,
but otherwise conditions remain VFR for the region.

LLWS: In advance of the cold front, vertical wind shear at 230
degrees and 30 kts at 2000 ft AGL will be possible over GGW
between 2 am and 6 am tomorrow morning.

Winds: South to southeast winds at 5-10 kts will turn to the
northwest and increase to 10-20 kts with gusts to near 30 kts by
tomorrow afternoon.




Flood warnings remain in effect for the Milk River and its
tributaries until further notice.

The Milk River continues to slowly rise from Dodson through
Nashua. The main concern is from Saco to Glasgow where Moderate
Flood Stage is expected to hold into next week.

The Frenchman Creek looks like it has crested, but due to high
water levels a Flood Advisory is still in effect for this in
northeast Phillips County.

Water levels on Beaver Creek continue to drop but with high water
around Saco the Flood Warning remains in effect.
