A very cold low pressure system will bring an extended cold snap to the region along with some gusty winds. High temperatures will struggle to pass the 60 degree mark along coastal sections for the next few days and nighttime lows will drop way down into the 40’s. [Current seasonal high temperatures are right around 66 degrees for LAX airport].

Discussion

A cold low pressure system will bring significant cooling to the region and possible showers and high temperatures may struggle to rise above the 60 degree mark later this week. Arctic air is plunging into the southern Rockies and Northern Plains over the next couple of days and at the same time, we’ll cool off significantly here in southern California.

7:00 AM | **Brutally cold Arctic air plunges into the region and there will be several inches of accumulating snow to accompany it**

6-Day Forecast

Today

Mostly cloudy today with increasing winds and decreasing temperatures and the likelihood for snow by later this afternoon, temperatures will peak in the 40's this morning and then will drop sharply towards freezing this afternoon

Tonight

Cloudy, bitter cold, periods of snow, some of which can be heavy at times, lows by morning in the upper single digits

Wednesday

Cloudy, bitter cold with more snow, temperatures holding steady in the single digits, accumulations by nightfall on the order of 4-8 inches

Wednesday Night

Mainly cloudy, cold, some evening snow still possible, lows near zero

Thursday

Mostly cloudy, still brutal cold, highs near 10

Friday

Partly sunny, very cold, near 15

Saturday

Mostly cloudy, still very cold, upper teens

Sunday

Partly sunny, very cold, near 20

Discussion

A brutal Arctic air mass will plunge into the region later today and temperatures by tomorrow morning are likely to be in the single digits. Snow will accompany this invasion of Arctic air beginning late this afternoon and continuing through Wednesday with several inches likely on the Plains on the order of 4-8 inches. To make matters even worse, strong winds will generate even lower wind chill values than the actual air temperatures during the next few days. Temperatures remain bitter cold late this week and weekend although there will be some slight modification in the extreme cold.

2:30 PM | *An incredibly cold Arctic air mass to cross country this week and it could eventually lead to problems in the Mid-Atlantic region*

Discussion

The calendar has turned to December and the signs are there for a very winter-like pattern across much of the nation during the next couple of weeks – the likes of which we haven’t seen in quite some time for this early in the winter season. An incredibly cold Arctic air outbreak is now gathering itself just above the US/Canada border region in southwestern Canada and it is about to plunge into the Northern Plains and Rocky Mountain region with painful results and temperatures some 40 degrees below normal. Temperatures by Wednesday and Thursday won’t rise above zero in parts of North Dakota and Montana and overnight lows could bottom out at 30 degrees below zero (GFS surface temperature forecast map for Thursday evening courtesy weather.cod.edu). Denver will experience plunging temperatures on Tuesday and might not be able to climb above 10 degrees on Wednesday and Thursday. To make matters worse, snow and wind will accompany this Arctic blast across the Rockies and Northern Plains during the next 48 hours or so.

This Arctic blast will continue on a trek towards the eastern states and could lead to potential problems for the Mid-Atlantic region. The initial cold front will likely pass through the Mid-Atlantic region by Friday or so, but it will then get hung up in a southwest-to-northeast direction not far from the east coast. At the same time, an active pattern may then produce wave-after-wave of low pressure that will ride along the frontal boundary from the moisture-laden Deep South towards this region. This type of pattern could ultimately lead to significant ice around later this weekend or early next week or even accumulating snow. There are signs for a second Arctic blast next week that will again affect much of the country. Stay tuned.

7:00 AM | **Bitter cold Arctic air plunges into the region on Tuesday; snow accompanies the Arctic blast**

6-Day Forecast

Today

Mostly sunny, windy, warm, highs in the low 60’s

Tonight

Partly cloudy, windy, colder late, lows in the upper 30’s

Tuesday

Mostly cloudy, turning colder, windy, chance for some snow shower activity, temperatures drop all day into the 20's by evening

Tuesday Night

Mainly cloudy, breezy, bitter cold, some snow likely, lows in the single digits

Wednesday

Mostly cloudy, bitter cold, snow likely, near 10

Thursday

Mostly cloudy, still bitter cold, chance for more snow, near 10

Friday

Partly sunny, still very cold, near 15

Saturday

Partly sunny, very cold, near 15

Discussion

The big news this week will be the tremendous Arctic blast that will affect much of the country as it treks slowly eastward. The Pacific Northwest will be the first region to feel its effects, but the southern Rockies will experience plunging temperatures by later tomorrow and snow is likely to accompany this next cold blast. Temperatures by Wednesday morning will likely be in the single digits and highs will struggle to climb above 10 degrees during the second half of the week.

Discussion

Surface high pressure over the northern Plains will push a weak cold front through the region resulting in slightly cooler conditions for Turkey Day. Temperatures will rebound some on Friday as the cool air mass shifts to the east of the southern Rockies.

A storm system will bring us clouds for the holiday, but high pressure will return sunshine to the region for the weekend. A cooler air mass is likely to reach the southern California region by the middle part of next week.

A storm system will come close enough to the region to spread clouds our way for Turkey Day and it'll turn cooler on Thursday as well. Beyond that, high pressure will build into the area and the weekend is looking quite decent with sunshine expected on both days.
