11:40 AM | Cold air moves in today and accumulating snow is likely early tonight

Discussion

Colder temperatures will follow a cold frontal passage later today and precipitation in the form of a cold rain is likely to move in initially behind the front later today, but then it should change to snow by the time sunset rolls around. Snow is likely tonight in and around the Denver metro area and on its eastern side to Aurora with 1-3 inches of accumulation likely by late tonight. Snow may linger tomorrow in the mountains, but clearing skies are likely around Denver. Tonight’s temperatures will drop to perhaps the lowest levels seen yet this season with upper teens possible by morning.

7:00 AM | Unsettled and cool pattern sets up for a couple of days

6-Day Forecast

Today

Mostly cloudy, a few showers possible, windy, quite cool, mid 60’s

Tonight

Mostly cloudy, windy, maybe a couple of showers, cool, low 50’s

Saturday

Mostly cloudy, maybe another shower or two, windy, still quite cool, low 60’s

Saturday Night

Partly cloudy, breezy, chilly, upper 40's

Sunday

Mostly sunny, warmer, upper 60’s

Monday

Mostly sunny, warm, low 70’s

Tuesday

Partly sunny, warm, mid 70’s

Wednesday

Mostly cloudy, cooler, maybe a few showers, mid 60’s

Discussion

An unsettled weather pattern is setting up for the area for the next couple of days as upper level low pressure deepens in the western part of the country. Temperatures will hold at very cool levels over the next couple of days and showers are possible through tomorrow. High pressure will build back into the area early next week and temperatures will warm up noticeably. Another low pressure system may affect our weather by the middle of next week.

7:00 AM | Next cold shot could result in weekend accumulating snow and the coldest night yet this season

6-Day Forecast

Today

Mainly sunny, still pleasant, highs in the mid 60’s

Tonight

Partly cloudy, chilly, upper 30’s

Saturday

Mostly cloudy, much colder, rain or snow showers possible, upper 40’s

Saturday Night

Mostly cloudy, windy, very cold (perhaps the coldest night yet), periods of snow likely with accumulations on the order of 1-3 inches, upper teens for lows

Sunday

Mainly cloudy, cold, maybe a few snow showers, highs near 30

Monday

Mainly cloudy, still cold, but not as extreme, low 40’s

Tuesday

Partly sunny, milder, but still below normal, upper 40’s

Wednesday

Partly sunny, chilly, highs near 50

Discussion

A big change is underway in the overall weather pattern for the western part of the country as a deep upper level trough of low pressure is building into the region. The upper level trough will move into the Great Basin region by tomorrow and our temperatures will drop considerably by the weekend. Snow is likely to accompany this next cold shot from Saturday night into Sunday with some accumulations possible on the order of 1-3 inches and there is a good chance that Saturday night will turn out to be the coldest night so far this season with temperatures bottoming out in the upper teens. Temperatures will slowly moderate during the early part of next week.

3:00 PM | Quiet spell on the sun has been broken today, but current solar cycle continues to "underperform"

Discussion

While it was predicted by some scientists that this solar cycle (#24) maximum coming next year would be one of the weakest in decades, it might actually turn out to be even weaker than they thought. The sun continues to “underperform” in terms of the number of sunspots and this solar cycle appears to be continuing a recent trend of weaker and weaker cycles. In fact, the current predicted and observed size makes this the smallest sunspot cycle since Cycle 14 in February of 1906.

For the past week or so, there were no strong solar flares as the sun was largely devoid of any sunspots. Just today, the recent quiet spell on the sun was broken as a new sunspot emerged over the sun’s northeastern limb and it unleashed an M-class solar flare. The Earth was not in the line of fire for this particular solar flare given the current location of this new sunspot on the edge of the sun. In about a week or so, this seemingly active sunspot will turn squarely toward the Earth and we’ll continue to monitor all of its activity here at thesiweather.com.

7:00 AM | Looks like a cool weekend coming

6-Day Forecast

Today

Some fog and drizzle early then becoming partly sunny, cool, low-to-mid 60’s

Tonight

Mostly clear, cool, a few showers likely, lows in the mid 50’s

Friday

Mostly cloudy, maybe a shower or two, breezy, quite cool, low 60’s

Friday Night

Mostly cloudy, breezy, maybe a shower, quite cool, low 50’s

Saturday

Mostly sunny, breezy, quite cool, low 60’s

Sunday

Mostly sunny, breezy, still quite cool, low 60’s

Monday

Partly sunny, warmer, cool, low-to-mid 70’s

Tuesday

Partly sunny, warm, mid 70’s

Discussion

High temperatures will drop today compared to recent days as a deep upper level trough of low pressure builds into the western states. At the same time, surface low pressure will gives us a chance for some shower activity in the overnight and on Friday. The below normal temperatures will continue right through the upcoming weekend.

Discussion

A big change is underway in the overall weather pattern in the western part of the country as a deep upper level trough of low pressure is building into the region. Temperatures today and tomorrow will hold at moderately cool levels, but will respond this weekend by dropping to below normal levels under the influence of the deep upper level trough.

Discussion

Temperatures will drop dramatically by Thursday as a deep upper level trough of low pressure builds into the western states. At the same time, surface low pressure will arrive to increase the chances for showers and that threat will continue through Friday. The below normal temperatures will continue right through the upcoming weekend.

Monday

Discussion

Strong upper level ridging will continue to move from the southwestern US to the central Plains during the next couple of days and this will allow for a deep upper level trough of low pressure to build into the western states by the end of the week. Friday is likely to be the last “warm” day of the week as temperatures will respond this weekend by dropping to below normal levels.

The week started off on the hot side, but will cool off dramatically by the upcoming weekend. High pressure will slowly give way to a cold and deep upper level trough of low pressure with lots of clouds and maybe even some shower activity later this week. Temperatures by the weekend will respond by holding at well below normal levels.

Until then, temperatures will hold at rather pleasant levels for this time of year, but the dramatic change is coming.
