WEATHER DISCUSSION - Wednesday February 05, 2024 -

SNOW IS NOT OVER YET...Colder air is now moving in with some lingering light snow showers this morning, with progressively colder air expected today, and really cold air tonight as more light snow moves in. On Thursday a strong storm moves through mainly later day - overnight, through Friday, with heavy snow expected, and it will be a colder and drier powder. This weekend could still go a couple of ways, lots of sun and chilly air, plus amazing conditions, or more clouds than sun, and some light and mostly non-accumulating snow, plus AMAZING conditions! Either way, you win with the conditions, and I am forecasting an in-between scenario, as high pressure ridging slowly builds in across the Pacific Northwest into early next week (through the 11th).

LONGER RANGE.

After a short break (from snow) early next week (mostly sunny), expect another round of snowfall mid and late next week, for about 3 days (through the 14th-15th), with frequent snowfalls expected, another 1 or 2 day break, then off and on snow through later February as we will then be mainly on the east side of high pressure ridging, with more sun mixed in with the snowfalls this time, and colder, drier air, as storms target the central US, so I am not expecting big totals from most of these systems (no mid-Pacific moisture connection or "atmospheric rivers" at this point, more over-land movement of systems). Meteorologist/ Chris Manly



WEATHER DISCUSSION - Monday February 03, 2024 -

THE TOTAL MOUNTAIN TRANSFORMATION CONTINUES...Deep moisture and strong dynamics continue as the pattern continues busy, with the snowfall continuing to bury the mountain in the best snow of the season. This will continue through Tuesday as a number of waves move through the large scale low pressure trough, tapping into good moisture from the Pacific Ocean. Plenty of wind will accompany the snow, with blowing and drifting expected, making measurements difficult to attain without the moisture equivalent being measured also, and coupled with temperatures during snowfall. Colder air moves in after lingering snowfall accumulations on Wednesday, with progressively colder air expected Wednesday, and really cold Wednesday night. On Thursday another strong storm moves through with heavy snow expected, mainly the 2nd half of the day but we will watch the timing. It will be a colder and drier powder. On a very cold Friday expect even colder and drier powder, maybe a few inches of it, as the last blast of this weeks action moves through. This weekend could go a couple of ways, lots of sun and chilly air, plus amazing conditions, or more clouds than sun, and some light and mostly non-accumulating snow, plus AMAZING conditions! Either way, you win with the conditions. I forecast an in-between scenario, as high pressure ridging slowly builds in across the Pacific Northwest.

LONGER RANGE.

After a short break (from snow) this weekend (8-9 Feb, mostly sunny), expect another round of snowfall next week, for about 3 days, with frequent snowfalls expected, another 2-ish day break, then snowy through mid February and beyond as we will then be mainly on the east side of high pressure ridging, with more sun mixed in with the snowfalls this time, and colder, drier air, as storms target the central US, so I am not expecting big totals from most of these systems (no mid-Pacific moisture connection, more over-land movement of systems). Meteorologist/ Chris Manly



WEATHER DISCUSSION - Sunday February 02, 2024 -

MASSIVE SNOWFALL... Lots and lots of snow thanks to strong dynamics, and a solid stream of moisture, for mostly continuous snow today and tomorrow, right through Tuesday and tapering off Wednesday... Expect a huge mountain transformation with daily snow all the way through next week, heavy at times, as low pressure shifts to focus on the Pacific Northwest. Multiple systems are expected through the weekend, with snow being heavy at times, and some drifting and blowing of snow. Daily snowfalls are expected through next Thursday or so.

LONGER RANGE.

After a short break next weekend (8-9 Feb, mostly sunny), expect another round of snowfall, for about 3 days, with frequent snowfalls expected, another 2-ish day break, then snowy through mid February and beyond. Meteorologist/ Chris Manly



WEATHER DISCUSSION - Friday January 31, 2024 -

TOTAL MOUNTAIN TRANSFORMATION... Expect a huge mountain transformation with daily snow all the way through next week, heavy at times, as low pressure shifts to focus on the Pacific Northwest. Multiple systems are expected today and through the weekend, with snow being heavy at times, and some drifting and blowing of snow. Daily snowfalls are expected through next Thursday or so.

LONGER RANGE.

After a short break next weekend (8-9 Feb, mostly sunny), expect another round of snowfall, for about 3 days, with frequent snowfalls expected, another 2-ish day break, then snowy through mid February and beyond. Meteorologist/ Chris Manly



WEATHER DISCUSSION - Monday January 27, 2024 -

We are under a big Pacific Northwest high-pressure ridge through Thursday, with mostly sunny skies. By Friday and through this weekend (on track with last forecast) expect a huge mountain transformation with daily snow all the way through next week, heavy at times, as low pressure shifts to focus on the Pacific Northwest. More details are coming, but February is roaring in like a lion.

LONGER RANGE.

Frequent snowfalls are expected in early February through the 9th/ 10th, with few breaks, snowy through mid February and beyond. Next Monday (3 Feb), low pressure starts digging into a LOT more Pacific moisture for heavier snowfall across southern Idaho, the PNW, and Bogus Basin. Meteorologist/ Chris Manly



WEATHER DISCUSSION - Thursday January 23, 2024 -

A strong and cold but mostly moisture-starved system will brush the area on its way south tonight through Saturday morning. Mostly just some clouds and periodic snow flurries are expected (no accumulation). AFter this, on Saturday the low drops south and a high pressure ridge starts building in, with chilly temperatures continuing as we are on the east side of a big Pacific Northwest high-pressure ridge, with mostly sunny skies. By next Wednesday and Thursday the ridge shifts and we have a chance for some snow late next Thursday through that weekend (first of Feb).

LONGER RANGE.

Frequent snowfalls are possible in early February, first several days, then another ridge (no snow), alternating with periods of snow again into mid-February. Don't worry, the snow is coming back. Meteorologist/ Chris Manly



WEATHER DISCUSSION - Friday January 17, 2024 -

Temperatures have remained cold and "snow-preserving" for Bogus Basin, so there remains a great base after some amazing snowfall thus far. Mostly sunny/ partly cloudy skies are expected through this weekend, with much colder temperatures as we are in a dry and unsettled pattern, low pressure east and high pressure west, some breeziness and wind chill at times the result, otherwise plenty of sun is expected. Some snow flurries are expected next Tuesday-Wednesday with a weak and mostly moisture-starved system brushing the area on its way southeast.

LONGER RANGE.

High pressure ridging (and tranquil snow-free weather) is mostly dominant through January 24 with mostly no snow and more sun (near to above average temperatures are expected mid-late next week. By around January 24-25, next weekend (Saturday snow) the jet stream starts cutting south into the west coast and delivering frequent snows to Bogus Basin and southern/ northern Idaho. There should be frequent significant snowfalls into early February. Meteorologist/ Chris Manly



WEATHER DISCUSSION - Monday January 13, 2024 -

Mostly sunny skies and chilly temperatures are expected today under building high pressure ridging aloft. Valley temperature inversions are expected (colder below, warmer above) under a mostly dominant high-pressure ridge over the Northwest US pretty much all week, except for late Thursday when a shot of flurries/ very light snow is expected into Friday morning, no accumulation or 1 inch is expected at this point. The good news is that temperatures remain cold and "snow-preserving", while there remains a great base after some amazing early-season snowfall in November and December. The SnoTel site shows just under 5 feet of depth and good water equivalent (16.4") as of this morning. The weekend remains chilly/ cold with a dry northwest flow on the east side of the big high-pressure ridge. Mostly sunny-partly cloudy skies are also expected through the weekend.

LONGER RANGE.

High pressure ridging looks to be mostly dominant through January 23 with mostly no snow and more sun (near average temperatures are expected as colder shots of air move in at times. After January 23 the jet stream starts cutting south into the west coast and delivering frequent snows to Bogu Basin and southern/ northern Idaho. Meteorologist/ Chris Manly



WEATHER DISCUSSION - Thursday January 9, 2024 -

Today things are looking mostly sunny and chilly with northwest breezes, more sun but increasing clouds on a less-cold Friday, then then some snow moves in Friday afternoon through overnight, a quick shot of moderate snowfall and a STRONG cold front as temperatures drop fast Friday night (near 32F then dropping to single digits at 10,000 feet), then Saturday looks Much colder than Friday, with some 10-20mph northwest breezes for wind chill. Sunday looks cold and mostly cloudy (partly sunny) with some flurries at times, clearing out Monday morning then becoming sunny/ cold Monday under building high pressure ridging aloft. Next Tuesday and Wednesday (14-15 Jan) look sunny and not as cold, with valley temperature inversions (colder below, warmer above) under a strong high-pressure ridge.

LONGER RANGE.

High pressure ridging fights to be dominant through January 21, with low pressure systems moving through carrying refreshing shots of cold air and maybe snow to freshen up the slopes here and there. After January 21 the pattern may start cutting south into the west coast and delivering frequent snows to Bogu Basin and southern/ northern Idaho. Meteorologist/ Chris Manly
