7:00 AM | A very nice weather pattern shaping up for the week and upcoming weekend

6-Day Forecast

Today

Mostly sunny, mild, highs in the upper 60’s

Tonight

Partly cloudy, cold, lows in the upper 40’s

Wednesday

Mostly sunny, pleasant, near 70

Wednesday Night

Partly cloudy, cool, near 50

Mostly sunny, pleasant, low 70’s

Friday

Partly sunny, warmer, mid 70’s

Saturday

Mostly sunny, pleasant, near 70

Sunday

Mostly sunny, mild, mid-to-upper 60’s

Discussion

A very pleasant week is in store for the region as offshore flow will persist bringing us dry conditions and mild temperatures. In fact, it’ll get downright warm and well above normal by late this week as high temperatures should surge to the middle 70’s by Friday as upper level high pressure builds into the region.

7:00 AM | Next disturbance brings us snow shower activity today, but nothing significant is expected

6-Day Forecast

Today

Mostly cloudy, breezy, snow showers likely, but not a significant event, cold, highs in the low-to-mid 30’s

Tonight

Mostly cloudy, very cold, snow showers still possible, lows in the middle teens

Wednesday

Mostly sunny, breezy, cold, mid 30’s

Wednesday Night

Partly cloudy, cold, low-to-mid teens

Thursday

Partly sunny, cold, upper 30’s

Friday

Mostly sunny, cold, near 40

Saturday

Mostly sunny, not as cold, mid-to-upper 40’s

Sunday

Partly sunny, mild, mid 50’s

Discussion

Another trough of low pressure will give us the chance for snow showers today and tonight, but unlike recent storms, this will not be a significant snowfall producer. While accumulations are possible from this system, they should be on the small side totaling an inch or less by later tonight. There are signs for milder weather to return to the southern Rockies later this week and weekend with high temperatures possibly surging to the middle 50’s by the time Sunday afternoon rolls around.

7:00 AM | The latest snowstorm pulls away from the region, but active pattern continues

6-Day Forecast

Today

Bitter cold start to the day, but mostly sunny skies will boost afternoon temperatures to the upper 30's

Tonight

Partly cloudy, very cold, lows in the lower teens

Tuesday

Partly sunny, breezy, cold, maybe some snow showers , but not a big deal, low 30’s

Tuesday Night

Mostly cloudy, cold, chance for some snow, middle teens

Wednesday

Mostly sunny, breezy, cold, mid-to-upper 30’s

Thursday

Mostly sunny, cold, upper 30’s

Friday

Mostly sunny, not as cold, mid 40’s

Saturday

Partly sunny, chilly, mid 40’s

Discussion

The major storm that generated more significant accumulating snow around here yesterday has pulled away and we’ll be dry today, but the morning will be bitter cold to begin the new week. Another trough of low pressure will give us the chance for snow showers on Tuesday and Tuesday night as the overall weather pattern remains quite active, but this does not look like a significant event. Late this week it looks like a drier and milder pattern will set up as high pressure builds in aloft.

7:00 AM | A pleasant week with dry and mild conditions

6-Day Forecast

Today

Mostly sunny, breezy and mild, highs in the mid and upper 60’s

Tonight

Partly cloudy, cold, lows in the upper 40’s

Tuesday

Mostly sunny, pleasant, near 70

Tuesday Night

Partly cloudy, cool, near 50

Wednesday

Mostly sunny, pleasant, near 70

Thursday

Partly sunny, pleasant, near 70

Friday

Mostly sunny, a bit warmer, mid 70’s

Saturday

Mostly sunny, still mild, mid-to-upper 70’s

Discussion

High pressure will promote dry and pleasant weather conditions around here for much of the week. High temperatures will come close to 70 degrees for the next few days and then should surge well up into the 70’s by late this week.

10:40 AM | **Major snowstorm continues today with 6-12 inches by midnight along with 40 mph wind gusts causing blowing and drifting**

Discussion

An intensifying storm over the Four Corners region this morning will bring another major snowfall to the Denver metro region with 6-12 inches likely by midnight. Snow will fall heavily at times right into early tonight and winds will become a significant factor as they’ll gust up to 40 mph out of the north causing some serious blowing and drifting. Roads will become snow packed and hazardous, and delays at Denver Airport are very likely. The snow winds down later this evening leaving us with dry, but cold weather to begin the new week although the overall weather pattern remains quite active.

4:50 PM | **Another major snowstorm for the Denver region from later tonight through Sunday afternoon with 6-12 inches possible**

Discussion

Another major snowstorm will hit the southern Rockies with significant snow from later tonight through Sunday afternoon. This storm will move to the Four Corners region by tomorrow morning and then track east from there while intensifying and the end result will be 6-12 inches in and around the Denver metro region by late tomorrow. Winds will gradually pick up in intensity overnight and can gust tomorrow up to 40 mph or so causing significant blowing and drifting. Roads will become hazardous during the storm and delays at Denver Airport are a very good bet. Drier weather will return tomorrow night and Denver, but it’ll stay on the cold side with additional snow threats next week as the active pattern continues.

7:00 AM | Dry weather pattern setting up; milder by early next week

6-Day Forecast

Today

Mostly sunny, windy and cool, highs near 60 degrees

Tonight

Partly cloudy, windy, cold, lows in the upper 40’s

Saturday

Mostly sunny, breezy, cool, near 60

Saturday Night

Partly cloudy, cold, upper 40’s

Sunday

Mostly sunny, pleasant, mid 60’s

Monday

Partly sunny, pleasant, mid 60’s

Tuesday

Mostly sunny, a bit cooler, low 60’s

Wednesday

Mostly sunny, milder, mid-to-upper 60’s

Discussion

High pressure will gradually build into the region over the next few days and promote a warming trend. By early next week, temperatures should reach well into the 60’s along with mostly sunny skies. Our overall weather pattern stays dry at least right into the middle of next week.

7:00 AM | Active weather pattern continues with several disturbances coming our way

6-Day Forecast

Today

Partly sunny, breezy, cold, snow showers possible, highs in the mid 30's

Tonight

Partly cloudy, cold, lows in the upper teens

Saturday

Increasing clouds, breezy, not as cold, upper 40’s

Saturday Night

Mostly cloudy, cold, chance for some snow, low 20’s

Sunday

Mostly cloudy, windy, chilly, chance for some snow, upper 30’s

Monday

Mostly sunny, windy, chilly, low 40's

Tuesday

Mostly sunny, chilly, near 40

Wednesday

Partly sunny, chilly, mid 40’s

Discussion

The major storm that generated significant accumulating snow around here has pulled towards the Great Lakes region and we’ll dry out some today, but it'll stay moderately cold and a few snow showers cannot be ruled out. There will be several disturbances coming our way over the next several days and each one will bring an enhanced chance for some snow beginning with the next system on Saturday night and Sunday. Precipitation amounts for the weekend system do not look too high, but gusty winds will follow early next week.

12:15 PM | It Ain't Over Till Its Over - winter that is

Discussion

A very interesting late winter weather pattern is forecast to evolve in the US over the next week or so. We often talk about “teleconnections” here at thesiweather.com and how atmospheric and oceanic patterns in one part of the world can have an effect on the weather pattern here in the Mid-Atlantic region. For example, the wintertime atmospheric pressure and sea surface temperature pattern in the North Atlantic can dictate whether cold air masses will penetrate into the central and eastern US from Canada and, if so, can they be sustained. One way to track the overall pattern in the North Atlantic is through an index called the North Atlantic Oscillation (NAO). If the NAO is negative, for example, a blocking pattern can set up in the northern latitudes (such as in the region between Hudson Bay, Canada and Greenland), and this typically results in cold air intrusions into the central and eastern US. In addition, the pressure pattern in the eastern Pacific can determine whether Canadian cold air masses can drop southward into the central and eastern US. One way to track the pressure pattern in the eastern Pacific is through an index called the Pacific-North American (PNA) pattern. If, for example, the PNA is positive then high pressure ridge is likely to set up along the US west coast and this typically pushes cold air masses into the US from Canada due to the circulation (clockwise) around high pressure.

Experienced snow lovers and “weather weenies” in the Mid-Atlantic region know that while there are no guarantees, the best pattern for cold and snow usually involves a couplet with a positive PNA and a negative NAO. We really haven’t had that couplet combination all winter, at least not more than for a couple of days at a time, but that may be about to change. All indications are that this type of “teleconnections” pattern will develop over the next week or so enhancing the chances for cold and snow in the Mid-Atlantic region by early March. While we have had a negative NAO reading at times this winter, the change to a positive PNA is quite a change in the eastern Pacific. It should result in a trough of low pressure to develop in the Gulf of Alaska and a corresponding downstream ridge of high pressure to form along the US west coast. This, in turn, should help to bring cold air southward into the US from Canada. One final note, experienced snow lovers and “weather weenies” also know that when the calendar flips to March, time is running short for snow as climatological temperatures begin to climb quite rapidly.

Stay tuned.

7:00 AM | Stays breezy and cool for the next couple of days

6-Day Forecast

Today

Mostly sunny, windy and cool, highs in the upper 50’s

Tonight

Partly cloudy, windy, cold, lows in the mid 40’s

Friday

Partly sunny, breezy, cool, near 60

Friday Night

Mostly cloudy, cold, upper 40’s

Saturday

Mostly sunny, cool, near 60

Sunday

Partly sunny, cool, low 60’s

Monday

Mostly sunny, cool, low 60’s

Tuesday

Mostly sunny, cool, low 60’s

Discussion

Areas of low pressure will keep the region quite breezy and cool for the next few days, but it appears a warming trend will begin early next week as high pressure arrives from the west. In general, it looks like temperatures will be close to normal next week along with relatively dry conditions as once high pressure arrives it will stick around for awhile.
