  • A change in pattern will allow much colder conditions to spread over areas east of the Rocky Mountains.
  • A prolonged dry period is expected in the Northwest, while the Santa Ana winds are possible in southern California.

A big change of pattern will be felt in the USA. UU In the next week, with notable changes in many places.

will be due to a change in jet stream, with a strong high-pressure crest at the upper level, or bulge to the north of the jet stream, developing over the west and a deep depression at the upper level, or immersion to the south in the jet stream over the East.

Next, we take a closer look at what we should know about the weather next week.

1. The Early Week System will bring Rain, Snow to the Center, East of the United States

A low pressure system will advance first to the Pacific Northwest this weekend and then to the Plains on Monday. Rain and snow from the mountains will spread west this weekend and north of the Plains and the Upper Midwest starting Sunday night. [MORE:Thunderstormprincipleswillbecauseyourwindstormwinds)

By Monday, rain and thunderstorms are possible from the Great Lakes south to east Texas and the lower Mississippi Valley, with some snow behind the cold front badociated with this system on the north level.

Early forecasts of the week

(Outline on the map is expected precipitation and snowfall until Wednesday)

This system will continue following eastward bringing rain from New England to the south, with a mix of rain, snow, sleet and freezing rain in some of the highest elevations in New England from Tuesday to Wednesday.

Thunderstorms can not be ruled out in the south, and some severe storms can be mild. Develop from Monday to Tuesday.

This cold front may remain on the east coast and a wave of low pressure may develop along this limit by the end of next week. At this time, it seems that this system will be far enough from the coast to avoid impacts along the coast, but there is a possibility that there will be some rain or snow on the coasts of the Mid and Northeast Atlantic. week.

2. Large temperature changes ahead

Behind the system of the first week, temperatures will suffer a noticeable drop as the tilt to the south in the jet stream moves to the east and allows colder temperatures to rise to the south.

In front of this system, temperatures will be well above average from the plains to the east coast, but will return to almost -a-slightly -under half of the average week to late.

High temperatures in the Midwest and much of the Northeast will be in the 40s and 50s to start the week, but they will only reach 20 and 30 by the end of the week. Further south, the highs in the 60s and 70s will be replaced with temperatures in excess of 40 and 50.

Cold temperatures will also be cold, with widespread declines in the 1920s as far south as in northern Georgia. Record cold temperatures are not expected, but given the recent stretch of mild conditions in the central and eastern US. UU., This change in temperature will be a shock to the system for many.

3. Lake-Effect Snow will develop a week from mid to late

The next pattern change will also bring the possibility of mid-week lake effect snowfall.

Temperatures should be low enough in the Great Lakes region to combine with warmer water temperatures that result in the development of lake-effect snow.

Northern Great Lakes will see the possibility of snow with lake effect starting on Tuesday, while eastern Great Lakes will probably have to wait until Wednesday afternoon.

Configuration for possible snow with lake effect in the middle or end of the week.

There is a possibility of heavy snowfalls locally in some of the Great Lakes snow belts where the wind allows persistent snow bands to produce moderate to moderate snowfall. strong for several hours.

However, it's too early to determine where the heaviest snow will be, so be sure to return to weather.com for updates.

In addition, several disturbances can also bring multiple rounds of light snow to portions of the Great Lakes, Midwest and Northeast next week.

4. Santa Ana Wind Event Possible

An upper level low pressure area will slide south from the Pacific Northwest to the Great Basin on Sunday. This will allow strong winds to develop on land on Sunday portions of Southern California.

Then there is the possibility of a strong Santa Ana event happening in Southern California as late as Sunday night.

Possible wind configuration of Santa Ana in Southern California the first week.

A high pressure area will be strengthened in the Great Basin earlier in the week, resulting in the development of a moderate to strong offshore gradient. In addition, the highest level depression of low pressure may persist in Arizona and New Mexico, which could help set the stage for a more widespread wind event.

What this means is that strong sea winds are currently expected to develop for much of next week in Southern California. The combination of dry conditions and gusts of wind has led to the issuance of weather warnings for parts of the area from Sunday night until Thursday.

There are some uncertainties in the forecast models, and some indicate that stronger sea winds may not occur until mid-week.

Otherwise, temperatures will be cold to start the week, but warmer than average temperatures are expected in much of the region by the end of the week.

5. A dry and foggy period is expected in the northwest

. After the low pressure system mentioned earlier brings rain and snow from the mountain to the northwest this weekend, the drier conditions will begin to develop on Sunday night.

A high-level ridge strong high pressure will accumulate in the northwest early next week and will remain for at least the next weekend.

A high pressure ridge will bring a period of dry conditions in the west.

The result will be a stretch of dry conditions throughout the region, probably until next weekend throughout the west. Temperatures will also generally be within a few degrees of average by the beginning of December in most of the Pacific Northwest.

This dry stretch will be a welcome change for many. The National Weather Service office in Seattle noted that November recorded 24 days of rain or snow there, which simply did not reach the 25-day record. In addition, Seattle tied for the second number of days with at least 0.5 inches of rain in November, with 8 days.

However, mid-week fog areas may develop and in some areas, fog conditions may not dissipate completely. In addition, this could affect air quality in parts of the northwest.
