Unseasonable warmth is forecast across a large portion of the Lower 48 this week. High temps will soar to 30-40 degrees above normal, with some areas as much as 50 degrees above normal. Dozens of daily temp records could be broken.

How warm will it be where you live this week? Check weather.gov.

With a high risk of excessive rainfall issued across southern California on Wednesday, do you know what that means?

Excessive Rainfall Outlook High Risk Days indicate potential for extreme impacts from flash flooding.

For more information about High Risk Days: www.wpc.ncep.noaa.gov/qpf/eroclimo/
A level 4 out of 4 high risk for excessvie rainfall is in place across a large portions of southern California, just north of Los Angeles for Wednesday. High Risk Days are a BIG DEAL. High Risks are only issued by WPC on about 4% of days, but account for one third of all flood-related fatalities and four fifths of all flood-related damages. Graphic showing the WPC Excessive Rainfall Risk Categories: no area/label, marginal, slight, moderate, and high. Each has a description. High risks mean widespread flash floods expected. Areas that don't normally flood could. Lives and property are in greater danger.

Heavy rainfall will result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations this week (Dec. 22-26) across portions of California. Mud and debris flows will be possible across foothill and mountain areas, including recent burn scars.
weather.gov
Be prepared for debris flows. Heavy rain can cause debris flows in minutes, potentially burying homes. Areas with low vegetation or recent wildfire burns are especially at risk. Have a plan for your family and be ready to follow instructions from local officials. Listen & watch for rushing water or mud or unusual sounds such as trees cracking or boulders knocking together.

Wildfires can spread quickly — by the time one is nearby, you may not have much time. Have an evacuation plan, and prepare an emergency supply kit ahead of time. Listen to local officials for emergency information and any evacuation orders.

A damaging windstorm today will contribute to Extremely Critical fire weather conditions. Wind gusts up to 100mph, temperatures near 70F, and relative humidity near 10% will yield high-end fire weather environment along/near the Front Range. Stay aware& follow instructions from emergency officials.
An infographic titled "Key Messages for Friday Dec 19 Fire Weather" from the National Weather Service's Storm Prediction Center, updated Dec 19, 2025, at 9:11 AM MST. It warns of "Extremely Critical Fire Weather Conditions for portions of the Colorado Front Range into far southeast Wyoming." Overview: A damaging windstorm today will contribute to Extremely Critical fire weather conditions. Wind gusts up to around 100 mph, temperatures near 70F, and relative humidity near 10% will yield high-end fire weather environment along/near the Front Range. Timing: Wind gusts of 40-70 mph and relative humidity of 15-30% are already occurring this morning. Critical and Extremely Critical fire weather conditions will continue through the evening with strong winds likely continuing overnight. Safety Actions: Use caution with any potential ignition sources. Stay aware and follow instructions from emergency officials.

Strong winds – especially starting on Wednesday – will not only bring plenty of precipitation, but also strong winds across the areas highlighted on this map. Strong winds will push further east into the northern Plains and Midwest on Thursday. See what to expect at weather.gov

It looks as though the🔥Heat Miser🔥has taken over the latest outlook for Christmas week (Dec 23-29)! There is a high probability of warmer-than-normal temperatures for most of the US. Alaska, the Pacific Northwest, and New England have a better chance of seeing "classic" Christmas weather.
A map titled "8-14 Day Temperature Outlook" issued by NOAA, valid for December 23 - 29, 2025. The map shows a high probability of above-normal temperatures across the vast majority of the contiguous United States. A large area of deep red, indicating a high likelihood (80-100% chance) of above-normal temperatures, is centered over the Southern Plains, covering Texas, Oklahoma, and surrounding states. This heat extends outward in shades of lighter red and orange to the Southeast, Midwest, and Southwest. Small areas in the far Pacific Northwest (Washington state) and the Northeast (New England) are shaded in blue, indicating a probability of below-normal temperatures. An inset map of Alaska shows the entire state covered in blue (below normal), while Hawaii is shaded in orange (above normal).

A second Pacific cold front will cross the Pacific Northwest Wednesday followed by another atmospheric river event. These will mean additional periods of gusty winds, mountain snow, and heavy to excessive rainfall with a renewed flooding threat. Make sure to check weather.gov for the latest.
Map showing forecast 72-hour precipitation totals across the Pacific Northwest and northern Rockies from Dec 16–19. Heaviest rainfall appears along the Washington and Oregon coasts, with lighter amounts inland across Idaho, Montana, and Wyoming. Map showing forecast 72-hour snowfall totals across the Pacific Northwest and northern Rockies from Dec 16–19. Significant snowfall is indicated in the Cascades and Rockies of Washington, Idaho, and western Wyoming, with lighter snow elsewhere.

Additional atmospheric rivers are expected to impact the West later this month. Given the significant river flooding already impacting Washington and Oregon, a continued risk of flooding and landslides is expected across the region through at least late December.
NOAA National Weather Service forecast updated December 11, 2025, details "Atmospheric Rivers affecting the Pacific Northwest and California into late December," specifically December 19-25, 2025. The text warns of heavy rain, high-elevation snow, high winds, and persistent flooding risks. Map (a) shows high and moderate risks for heavy precipitation and snow across the region. Map (b), the "8-14 Day Precipitation Outlook," indicates a high probability of above-normal precipitation for most of the western U.S.
