High pressure currently over the western states will gradually weaken through this period, leading to a cooling trend and a return of marine layer low clouds and fog. Low clouds/fog are absent due to the Santa Ana winds which also brought warmer conditions west of the mtns this afternoon. High pressure will remain aloft for the Thanksgiving holiday, leading to communities seeing highs about 5 to 10 degrees above normal. An area of low pressure off to the west will will help bring in high clouds across the region as well. The flow will become more zonal as high pressure weakens over the southwestern U.
- Drier and cooler conditions prevail for the rest of the of the week. - Rain returns to the forecast this weekend with an approaching cold front/upper level disturbance from the west.

A weakening cold front is expected to bring a chance for light rain primarily to Del Norte and northern Humboldt counties on Thanksgiving Day. A cooling trend follows for the weekend with dry conditions and a chance for freezing temperatures during the morning hours.
- Scattered showers and thunderstorms today ahead of an approaching cold front.
With this low coming in from the northwest, this will help produce a slightly better chance of moisture for the Snake Plain and bench areas. Winds do pick up with this low passing through, but nothing widespread and of significance it appears right now.
429 AM CST Thu Nov 27 2025 - Much cooler and drier air will continue to surge into the area for the remainder of Thanksgiving Week. In the near term, cold high pressure ridging southward through the lower MS Valley will bring continued dry conditions with below normal temperatures.
- Scattered showers and thunderstorms today ahead of an approaching cold front. A cold front currently over central FL associated with a system in the eastern US will push through the area later today as a longwave trough digs into the eastern half of the country. Afternoon high temps will be in the low to middle 80s. The front should clear the peninsula early this evening, and behind the front much cooler and drier air will filter into the region.
Breezy winds will make it feel even cooler this morning, with wind chills in the teens.
* A pattern shift will bring cooler temperatures to the region over the weekend.
Well above normal temperatures are expected again on Thanksgiving Day before cooling develops over the weekend as an upper low approaches the area. A weak ridge will slowly slide off to the east today and hgts will fall from 582 dam to about 579 dam during the day.
- A cold front will bring light snow and gusty north winds to much of the area Friday through Friday night. Otherwise, most locations will see a partly sunny Thanksgiving with warmer than normal temperatures, generally peaking into the 40s across lower elevations. The northwest flow will give way to a trough that will drop south out of Canada into the Pacific northwest tonight, approaching Wyoming by Friday morning. Near the surface, an associated cold front will move north to south across Wyoming beginning mid-morning. The placement of the trough will keep snow most widespread east of the Divide, though a lack of more robust moisture (PWATs in the 0.

A cold front passing through the region is producing a band of light to moderate rain that is now impacting sites PSC/PDT/ALW, with precip ending before 20Z. /issued 312 AM PST Thu Nov 27 2025/ A pacific warm front was draped roughly along the Columbia River overnight. By midday the low pressure off the coast will be moving inland, increasing pops across the WA and OR Cascades again to 80-95%. The rest of the week is a relatively dry period for much of the lowland areas.
Until then however, temps are quite mild for late November with upper 40s to mid 50s in place across the lower valleys this afternoon. Looks like precip will mostly be limited to the higher terrain of the central mountains, along the Montana Divide and into the eastern highlands. Cooler temps tomorrow will support snow as the dominant precip type in these areas but this system won't have much moisture with it so with QPF generally around a tenth or less, snowfall amounts are likely to be an inch or less for most areas that do see precip. Not expecting much, if any, precip to fall in the lower valleys tomorrow although a stray shower or two is certainly possible. Temps Friday will be about 5- 10 cooler than today with them continuing to trend down as we move into the weekend.

123 PM MST Thu Nov 27 2025 - Two cold fronts will move through the area this weekend, bringing much colder temperatures and chances for minor snow accumulations. Some of this precipitation may become a mix (rain/snow) as a surge of warmer temps in the mid-levels move in and helps surface temperatures soar into the 50s for many locations. As the front passes through, widespread snow is possible as winds shift to the north which allows a surge of cold Canadian air to move into the CWA, making temperatures plummet Friday night as lows bottom out in the low teens to possible single digits in a few areas. A train of troughs will move through the Intermountain West to give renewing snow chances on an almost daily basis.

-Relatively cooler and drier conditions have settled in courtesy of a nighttime cold front passage. The last Friday of November opened with cooler temperatures and windy conditions across the Florida Keys. A rapidly moving cold front passed over the island chain yesterday, and brought a burst of 25 knot sustained winds, dew points in the 50s, and layers of stratus clouds across the eastern waters. High pressure over the eastern CONUS will keep breezes fresh to strong across the nearshore and offshore waters. From synopsis, a cold front across the area will maintain fresh to strong north to northeasterly breezes, and Small Craft Advisories will likely extend through Saturday night. Another cold front may be on the horizon for the middle of the week, reflected in the breezes turning around the clock ahead of it.
206 PM CST Fri Nov 28 2025 - Strong cold front set to move through Saturday with some light snow possible across central KS.
A cold front will bring a brief band of precipitation through the area with snow levels around 4000-5000' today. The cold front will clean out the inversion and mix out the fog in the valleys by this afternoon, with breezy west-northwest winds.
1254 PM EST Fri Nov 28 2025 -Slightly cooler temperatures and dew points after yesterday's cold frontal passage. From synopsis, a cold front across the area will maintain fresh to strong north to northeasterly breezes, and Small Craft Advisories will likely extend through Saturday night.

627 PM CST Fri Nov 28 2025 - Strong cold front set to move through Saturday with some light snow possible across central KS.
Large, positively tilted trough continues to dig down over the Rockies, coming out into the Plains tonight. Main low will be well to the south, but inverted trough will extend into our southern counties for a while tonight and tomorrow. Short range guidance is not handling the currently extend of MVFR conditions well compared to obs/satellite and I am not as confident based on trends that prevailing VFR will arrive farther north before the low pressure system brings near low stratus into the region and I made more pessimistic adjustments to better reflect current trends. The best chance for prolonged VFR conditions may not arrive until much drier low level air advects in behind the low pressure (winds shifting to the northwest) late Saturday afternoon and evening, otherwise the pattern will continue to support highly variable ceilings.
-Slightly below average temperatures and dew points continue tonight after yesterday's cold frontal passage.
- Gusty north-northeast winds are expected this evening and Saturday night following a cold frontal passage.
