Sunny skies, longer days and high pressure brought mountain temperatures close to 40 degrees yesterday as light ridgetop winds blew southwest at 10-15 mph.  Today will be a supersized version of yesterday: sun, mountain temperatures reaching the mid to upper 40s and calm winds.  It'll be an SPF 40 day, although if you dare to expose your pasty white arms or legs, I'd lather on the hundred. Tonight we'll see a few high clouds roll in, but there's no precipitation on the horizon until Thursday. Maybe.

A dominating ridge of high pressure has once again parked it over southwest Montana producing cool nighttime lows and warm daytime highs.  Yesterday, skies were mostly clear but mountain temperatures struggled to break 30 degrees and winds were light out of the S-SW at 10-15 mph.  Currently mountain temperatures are in the low to mid twenties but will climb steadily into the mid to upper 40's F by this afternoon and winds will stay light out of S-SW at 5-10 mph.

A moisture laden cold front has swept over southwest Montana depositing 2-5 inches of snow in the upper elevations of our advisory area.  The southern Madison Range was the grand recipient of this storm picking up 4-5 inches of new snow while the northern Madison Range picked up 3 inches.  The northern Gallatin Range, Bridger Range and mountains around Cooke City only picked up 1-2 inches.  Temperatures have remained relatively warm with nighttime lows dropping only to the mid twenties while highs today with reach the mid to upper thirties.  Winds have been blowing 5-10 mph out of the N through much of our advisory area although stronger winds are being recorded in the Bridger Range blowing at 15-25 mph out of the N and in the Lionhead area at 20-30 mph out of the S.  Moisture will taper off today leaving mostly cloudy skies and warmer temperatures.  A ridge of high pressure will bring sunny skies and above average temperatures for the early part of the week.

This morning temperatures were in the mid to high 20s F with southerly winds blowing 15-30 mph.  Much needed snowfall should arrive this afternoon with an associated cold front.  Temperatures will reach the low 30s but start to cool later today.  Winds will calm midday then shift to the north this afternoon bringing cold air as moisture comes from the west.  This spring storm is moving fast but should deposit 3-5 inches of snow by tomorrow morning.

Yesterday's weather was sunny, windy, and relatively cool.  With continued wind and a few clouds overnight temperatures didn't drop too much and were near 20 degrees F this morning.  Winds were blowing 10-20 mph from the W and SW though they blew a bit stronger yesterday afternoon.  Today will be noticeably warmer than yesterday, but a few clouds and gusty winds will prevent temps from feeling too hot.  Winds will stay strong and gusty blowing mostly from the SW at 20-25 mph and mountain temperatures will reach the low 30s F.

Yesterday's storm deposited a few more snowflakes before skies cleared in the afternoon.  This morning temperatures dropped to the single digits F with westerly winds blowing 10-20 mph.  Around midnight winds increased in the Bridger Range and were gusting up to 30 mph at all elevations.  A ridge of high pressure is building over southwest Montana today.  Winds should stay about the same and temperatures should warm to the low 20s F by late this afternoon under mostly clear skies.

A trace to an inch of new snow fell in the mountains last night.  It's still flurrying, and Bozeman seems to have gotten more than the upper elevations.  Ridgetop winds are only 5-10 mph out of the west-southwest with mountain temperatures in the low teens.  This weak, somewhat pathetic system is being pushed out today.  I only expect another inch at best.  Winds will remain light and westerly with temperatures reaching the 20s this afternoon before dropping into the teens tonight.  High pressure returns tomorrow with sunny skies and above average temperatures through Friday.

Sunny skies have exited and a weak system resembling winter will roll in tonight. Mountain temperatures are currently in the high teens to low twenties with light 5-10 mph winds blowing east-southeast.  Speeds will remain light, but the direction will swing to the south then westerly as the system tracks over Montana. Temperatures will remain cooler and only reach the mid twenties today.  Clouds will increase bringing snow showers tonight. By morning 1-2 inches will fall in the southern mountains and only one inch in the north.  Looking further out, light snow ends tomorrow and high pressure returns on Thursday bringing sun and above normal temperatures.  Ouch.

High pressure and spring like conditions continue to dominate the weather pattern in southwest Montana.  Temperatures have remained well above average with highs in the 40's F and lows in the 20's F and winds have remained light out of the west at 5-10 mph.   Currently, temperatures are in the upper twenties to low thirties and winds have picked up slightly out of the west at 10-15 mph.  As the day progresses we should start to see increasing clouds with continued warm temperatures reaching into the mid to upper 40's F.  Southwest Montana could see a slight change in weather starting tomorrow.

High Pressure has once again parked it over southwest Montana creating spring like weather that feels much more like April than March.  Temperatures have been well above normal with highs in the upper 40's F and lows in the 20's F.  Winds have been light out of the S-SW at 5-10 mph.  Today will be a near carbon copy of yesterday with highs reaching close to 50 degrees and lows dropping into the 20's F by tomorrow morning.  Winds will remain light out of the S-SW at 5-10 mph.
