KEY MESSAGES

- Colder than normal temperatures through Monday morning; morning lows from the teens west to single digits below zero east.

- Increased winds along the western foothills Monday night and Tuesday; localized blowing snow possible.

- Another system may bring rain and snow showers Tuesday into Wednesday (moderate chance).

- Unsettled conditions continue Thursday into the weekend.

UPDATE

Dry northerly flow exits over the region this evening. With snow cover & light winds, temps have dropped quickly since sunset over eastern valleys. Already -5F at Baker, -3F at Miles City and -2F at Hardin as of 7pm. Have adjusted forecast lows down a few degrees accordingly. Flow aloft is becoming anticyclonic and this will yield warm advection and a modest increase in west winds along the western foothills tonight. Seeing ~20 mph gusts at Springdale now. Temps along the western foothills may have already bottomed out before gradual warming overnight. There is an area of fog/stratus in Carter County, and all indications are that this will dissipate overnight with the shift to light downslope winds. JKL

AVIATION

Other than a small area of fog/stratus in Carter County tonight (which should dissipate before 12z), VFR will prevail regionwide under building high pressure aloft. SW-W winds will turn breezy along the western foothills later tonight and Monday. Look for 25-35 knot gusts at KLVM-K6S0-KHWQ. This may cause localized blowing snow where there is snow cover, but confidence for BLSN affecting KLVM is low. JKL
