Today through Friday night .
Clouds will increase through the day Thursday, ahead of the next cold front. Highs will reach the upper 50s to lower 60s in a pre-frontal environment. The front will push in late Thursday afternoon through Thursday evening. This front is not expected to be quite as strong as the one of Sunday night, but still has some punch to it. Winds will gust to 30 mph as the front moves through. Rain and snow will develop behind the front, with the start time mainly in the overnight hours (with the exception over the mountains which may see some precipitation as early as late Thursday afternoon). Temperatures will fall overnight with a mix of rain and snow turning to all snow by midnight for most locations.
The latest model trends this evening is hitting the Red Lodge vicinity with much higher precipitation, although some of it comes before snow levels drop. It is enough to boost our potential accumulations to 3-4 inches rather than the 2 inches we had previously. So areas that get heavier snow (closer to the foothills) will see some slush accumulate on the roads. The Beartooth Foothills also have some potential for similar enhanced snow overnight, but will depend greatly on the direction of the upslope flow, and how long that upslope lasts. At this time, the foothills near McLeod look to see an extended period of north to northeast flow, which should bring similar snow amounts to those seen in Red Lodge. More easterly flow favors other locations like Nye. Snow totals generally look to be in the trace to 2 inch category outside the mountains and foothills, but will have to keep a close eye of possible icy/slushy road conditions for the Friday morning commute. Additionally, there is a possibility of brief icy conditions in the 5-9 am time frame, as surfaces respond to the air temperature falling below freezing.
The system will linger through the day Friday, with cyclonic flow, but snow should become lighter with ground temperatures responding to a high April sun angle, leaving roads just wet. Have boosted PoPs again for Thursday night into early Friday thanks to model of some decent short term dynamics and surface convergence/upslope. Highs will struggle to get out of the upper 30s on Friday for may areas. Friday night will be drier as zonal flow takes over. BT/Gilstad
Saturday through Friday .
Little in the way of changes for the extended forecast period, with a progressive, unsettled pattern in place.
Weak upper ridging will bring dry weather across much of the region to start the day Saturday. The ridge will be moving eastward through the day, as an upper trough moves into the Pacific Northwest. The trough looks to spread moisture and pieces of energy across areas west of Billings in the afternoon. Low- level southeasterly flow will also bring in more moisture from the central plains. The increased moisture and lift should bring a few rain showers and mountain snow showers west of Billings Saturday afternoon/evening. At this time, much of the energy seems to shift north of the CWA, keeping eastern zones generally dry.
The upper trough will move across the region Sunday through Tuesday, bringing precipitation potential across the region for much of that time. Precip should be rain for the lower elevations and snow for the mountains. Snow levels decrease to near 5000 feet on Tuesday morning, but then rise again afterward.
On Wednesday, conditions should dry out as upper ridging builds over the region. But once again, the ridging appears short-lived, as another wave is progged into the region beginning Thursday afternoon, and continuing into Friday. This wave will bring another wave of mountain snow, and rain over lower elevations from Billings westward.
High temperatures will generally be in the 50s and 60s Saturday and Sunday, then 50s Monday and Tuesday, and 60s Wednesday and Thursday.
VFR conditions will prevail this morning, under increasingly cloudy skies, ahead of an approaching cold front.
The cold front will shift winds northwest across southeastern Montana, as it moves north to south across the region late this morning and early this afternoon. CIGS are expected to fall to MVFR/IFR levels as rain turns to snow this evening. MVFR to IFR conditions will prevail overnight and into Friday morning.
Mountains will become obscured this morning, and remain so through Friday morning.
