High pressure to our south will remain an influence on our region for next 24 hours with drier weather in store. A warm front crosses today though with a 500 mb trough hovering aloft. It may be an SPS is hoisted across the higher ridges of Pocahontas and Randolph today. Temperatures will be much warmer than yesterday thanks to this warm front with the lowlands reaching the mid to upper 50s in spots. The mountains of course will be a bit cooler ranging from the mid 30s to the lower 50s. Lows Wednesday night will be on the colder side with 20s and 30s expected area wide as a quick, but dry cold front moves through.
Lake induced/enhanced showers continue early this morning as west- northwesterly flow prevails under broad upper-level troughing. Some of the steadier/heavier showers early this morning could fall as snow, primarily across the higher terrain, with minor accumulations possible, but a transition to largely rain showers area-wide will be the case today as temperatures rise into the upper 30s and low 40s by the afternoon.
VSBYs and/or CIGs for KALW/KPSC may drop to MVFR conditions or lower from the low clouds and/or fog/mist. We will continue to be under the influence of a ridge over the next day, that will continue our pattern of dry and light conditions save for some mountain rain showers over the Cascades. Abundant upper level moisture coupled with the increases influences of an incoming trough will bring overcast skies through the night.
- Trending warmer for the remainder of the week. Cross sections otherwise show moisture confined to the lowest 7k feet and minimal forcing, thus, minimal impacts. Northwest flow strengthens between Canadian high pressure over western Quebec and high pressure off the Gulf coast. The low-level jet strengthens to about 40-45 knots but forecast soundings depict mixing just shy of these 850mb winds, resulting in westerly wind gusts near 30 mph. Highs today will creep even warmer than Tuesday, further thawing the weekend's snowpack.
Another clear, chilly night on tap with several spots around the area already falling to the freezing mark as of 05z.
Some spots along the coast, particularly along the Treasure Coast, may only see lows falling into the low 50s.
110 AM PST Wed Nov 12 2025 Updated at 108 AM PST Wed Nov 12 2025 * Unseasonably warm temperatures today through Wednesday * Strong, gusty winds in Central Nevada Thursday * A drier, warmer weather system will impact the state late this week according to latest model runs No Changes are planned this morning as forecast remains on track.
High pressure to our south will remain an influence on our region for next 24 hours with drier weather in store. A warm front crosses today though with a 500 mb trough hovering aloft. It may be an SPS is hoisted across the higher ridges of Pocahontas and Randolph today. Temperatures will be much warmer than yesterday thanks to this warm front with the lowlands reaching the mid to upper 50s in spots. The mountains of course will be a bit cooler ranging from the mid 30s to the lower 50s. Lows Wednesday night will be on the colder side with 20s and 30s expected area wide as a quick, but dry cold front moves through. A shallow warm sector will only allow for high temperatures to remain in the 50s across the lowlands.
(Tonight through Thursday) As mid-level ridging become settled over the center of the country, quiet weather conditions and a gradual warming trend will take place through the short-term forecast period. Expect afternoon highs in the mid to upper 70s Wednesday afternoon, inching into the low to mid 80s by Thursday afternoon.
- Trending warmer for the remainder of the week. Cross sections otherwise show moisture confined to the lowest 7k feet and minimal forcing, thus, minimal impacts. Northwest flow strengthens between Canadian high pressure over western Quebec and high pressure off the Gulf coast. The low-level jet strengthens to about 40-45 knots but forecast soundings depict mixing just shy of these 850mb winds, resulting in westerly wind gusts near 30 mph.
A bit more progressive pattern aloft this morning continuing to feature a W CONUS ridge and E CONUS trough, with the trough axis having pivoted offshore into the W Atlantic allowing some ridging aloft to build northward over the peninsula from the N Caribbean/S Gulf. At the surface, high pressure centered over FL and the NE Gulf has led to light winds and continued dry conditions, with another cold morning across the area owing to efficient radiational cooling with freezing temps particularly over parts of the Nature Coast that remain cloud-free, and chilly 30s and 40s elsewhere.
443 AM MST Wed Nov 12 2025 - High pressure remains in control keeping warm and dry conditions across the area. Ridging remains the dominant feature over the Intermountain West though this will start changing as a long wave trough approaches from the west. There will be an increase in mid and high cloud cover thanks to an upper level jet that will ride up and over the ridge which may temper high temperatures some.
- A trough will move into the area later this weekend with chances for precipitation and cooler temperatures. Upper level ridge axis will slowly translates eastward across the Front Range Wednesday and Thursday with upper level flow becoming a little more westerly each day. This will result in slightly warmer temperatures with downslope winds expected. Temperatures today and Thursday will climb into the 60s with a few areas across far eastern Wyoming and western Nebraska seeing highs peaking in the low to mid 70s by Thursday afternoon.
More widespread precipitation will arrive late this afternoon into Thursday as the low approaches the area. The general indication at this point is for the low to reach the Oregon/California coast.
305 AM PST Wed Nov 12 2025 * High confidence that a trough of low pressure will bring gusty winds and increased precipitation chances to the region late Thursday through the weekend, but low confidence in details and impacts.
522 AM CST Wed Nov 12 2025 Updated at 522 AM CST Wed Nov 12 2025 - A moderate risk of rip currents is expected along the Lower Texas Coast through this evening. A deep 500mb trough across the Great Lakes and eastern CONUS gradually swings into New England into the weekend, with high pressure building across Deep South Texas.
High pressure will keep conditions dry and mild today.
Westerly wind gusts between 25 and 30 mph will limit the perception of the warmer temperatures. Lows tonight to range from near 30 north to the lower/middle 30s south. Mid-level ridging will begin to build into the Ohio Valley and Great Lakes late in the week into the start of the weekend.
656 AM EST Wed Nov 12 2025 Another area of low pressure will move through the region today and Thursday, which will bring additional rain and snow showers. High pressure builds into the region for the weekend, with drier weather for the area. Temperatures will trend a bit warmer throughout the remainder of the week. Precipitation type is a bit more uncertain for tonight as the lake temperatures are still warm and with steep low level lapse rates thanks to heating from the lakes, surface temperatures down wind of the great lakes may warm into the mid 30s, producing rain in the lower elevations. Lake effect will continue through Thursday with rain likely in the lower elevations and possibly a mix across higher terrain.
Meanwhile, a 500-hPa ridge will be in place over the Pacific Northwest, turning flow aloft southwesterly. Tangible weather resulting from subsidence under the ridge will be twofold: first, it will keep an inversion in place over the Columbia Basin, leading to patchy/areas of fog through the morning hours where light winds and a sufficiently moist boundary layer are present; second, it will lead to warm afternoon temperatures where the inversion breaks, most notably in central and northeast Oregon.
401 AM MST Wed Nov 12 2025 - Warmer than average temperatures (5 to 15 degrees) and dry conditions continue through Thursday.
Lake induced/enhanced showers continue early this morning as west- northwesterly flow prevails under broad upper-level troughing. Some of the steadier/heavier showers early this morning could fall as snow, primarily across the higher terrain, with minor accumulations possible, but a transition to largely rain showers area-wide will be the case today as temperatures rise into the upper 30s and low 40s by the afternoon. some patchy refreezing in colder interior locations where surfaces remain wet could make for some slick roads tonight/ Thursday morning. A much quieter stretch of weather is on tap to wrap up the workweek as mid and upper-level ridging builds into the Great Lakes.
Winds out of the SW will bring a return of some surface moisture and warmer temperatures into the area as Gulf modulated air is able to creep in.
(Today through Thursday) A weaker, but still present eastern CONUS trough will remain in place through the period. At the surface, high pressure will center over the eastern Gulf and result in a more maritime easterly low-level flow pattern. Even with these changes, we'll still remain a few degrees below normal on the lows and highs through Thursday.
348 AM MST Wed Nov 12 2025 - High pressure remains in control keeping warm and dry conditions across the area. Ridging remains the dominant feature over the Intermountain West though this will start changing as a long wave trough approaches from the west. There will be an increase in mid and high cloud cover thanks to an upper level jet that will ride up and over the ridge which may temper high temperatures some.
201 PM EST Wed Nov 12 2025 Warming trend through the week with high pressure in control.
By this weekend, as the warming trend continues, much of Deep South Texas will be in the low 90s, well above normal for this time of year. Forecasts models continue to slow and stall the cold front mentioned in the previous forecast packages northwest of the CWA. Generally favorable conditions are expected on the waters off the lower Texas coast this week.
146 PM EST Wed Nov 12 2025 Another area of low pressure will move through the region today and Thursday, which will bring additional rain and snow showers. High pressure builds into the region for the weekend, with drier weather for the area. Temperatures will trend a bit warmer throughout the remainder of the week. Precipitation type is a bit more uncertain for tonight as the lake temperatures are still warm and with steep low level lapse rates thanks to heating from the lakes, surface temperatures down wind of the great lakes may warm into the mid 30s, producing rain in the lower elevations. Lake effect will continue through Thursday with rain likely in the lower elevations and possibly a mix across higher terrain.
High pressure keeps dry conditions in place through the weekend. Clear skies continue with high pressure across the area and a very dry air mass in place with PWATs around a half inch.
Issued 200 PM CST Wed Nov 12 2025 Tonight through Thursday night: West to northwest winds will decrease into the evening as the low pressure pushes east with higher pressure pushing in and reducing the pressure gradient across the CWA. This will come as ridging overhead pushes in Thursday keeping conditions largely clear across the CWA.
A mid-level high over the southwestern Gulf with ridging over South Texas will promote dry conditions and above average temperatures throughout much of the upcoming forecast. Confidence for a cold front to bring rain to portions of our CWA is waning with the latest model runs regarding a Pacific low bringing a front through the region. Recent global guidance is showing the low opening up and getting embedded into the overall flow as it approaches the Rockies from the west and staying just north of the Southern Plains. Resulting in the cold front stalling north of our region, thereby further limiting rain chances for South Texas.
Continued mild and dry through most of Thursday in Idaho, but cooling in Oregon Thursday as a weakening Pacific cold front comes inland. The supporting upper trough off the coast has formed a closed low near 39N/139W. The low is headed for southern California while the northern portion moves rapidly eastward along near the Canadian border. The trough will be weakest as it passes through our area, and the cold front will also weaken Thursday night but still be able to scour the weak inversion.
909 AM PST Wed Nov 12 2025 * High confidence that a trough of low pressure will bring gusty winds and increased precipitation chances to the region late Thursday through the weekend, but low confidence in details and impacts.
1132 AM MST Wed Nov 12 2025 - Warmer than average temperatures (5 to 15 degrees) and dry conditions today and tomorrow.
An upper-level ridge develops over the central Plains to end the week.
- Warmer and more humid for the rest of the week. High pressure and southerly winds will lead to a continued warming trend through the weekend.
Ridging crests over the region today, keeping warm, dry, and overall quiet conditions in control. Flow aloft switches to southwesterly this evening as the ridge axis pushes east and a trough digs down the West Coast. A modest 70-80 knot southwesterly jet ahead of the trough will nose into the region, bringing increased warm air and increased upper level moisture. Areas where clouds stick around into the afternoon, particularly for areas south of I-70, could see afternoon highs a few degrees cooler than deterministic guidance suggests. And enjoy those aurora! Attention turns to a low pressure system currently making landfall in Southern California.
(Rest of Today and Tonight) The upper level trough that brought anomalous cold conditions across the Southeast to start this work week continues to lift off to the northeast. Under mostly sunny skies, expect afternoon temperatures to rise into the low to mid 60s which is near the climatological normal for this time of year.
Elevated Westerly Winds this Afternoon Across Inland Southeast GA (Through Tonight) A weak southeast moving cold front will pass to the north of the area this afternoon and evening. High pressure ridging will remain in place across area through the night. The center of the high Tonight will be just to the west of the area, providing a light west/southwest flow.
1245 PM EST Wed Nov 12 2025 High pressure will hold over the Mid South and Southeast through the rest of the week. High pressure will remain over the deep south through tonight. A weak Appalachian surface lee trough will exist in the overall WSW flow. The low levels will stay dry, however, so no precip is expected.
A few light showers in association with a warm front that is traversing across the region are moving north across west- central Washington and continue to move northward this morning. Showers will increase overnight into Thursday as the low approaches the area. The general indication at this point is for the low to reach the Oregon/California coast.
Issued by National Weather Service Reno NV 1114 AM PST Wed Nov 12 2025 Updated at 1112 AM PST Wed Nov 12 2025 * Unseasonably warm temperatures through Thursday * Strong, gusty winds in Central Nevada Thursday with patchy blowing dust * A drier, warmer weather system will impact the state late this week according to latest model runs (This afternoon through next Wednesday) WEATHER PATTERN OVERVIEW: Satellite imagery this afternoon is showing a mass of mid and high level clouds over northern and central Nevada this afternoon. An upper level trough will appear on the west coast of the United States on Thursday.
An upper trof over the interior eastern states moves off into the western Atlantic through Thursday as an upper ridge progresses into the central CONUS.
Upper-level ridging will prevail over the western and central Gulf Coast region through the end of this week. Overall trends with the model guidance continue to show upstream weather pattern will dig trough farther west this weekend.
Over the weekend, cooler and wetter conditions anticipated. Hard to believe we are nearly halfway through November and temperatures are still in the 50s and 60s across much of the High Country! Daytime highs look to land 5-15 degrees above normal through the end of the work-week, as an area of high pressure remains settled over Arizona.
1250 PM EST Wed Nov 12 2025 High pressure will hold over the Mid South and Southeast through the rest of the week. High pressure will remain over the deep south through tonight. A weak Appalachian surface lee trough will exist in the overall WSW flow. Trended forecast on the cooler side of guidance and results in mainly in the 30s areawide (warmest in urban areas). Pockets of sub-freezing temperatures across the rural Piedmont will be possible.
(Tonight) At 19Z, high pressure was sitting over the northeast Gulf of America with westerly flow now advecting warmer and more moist air/higher dew points into the deep South, mainly just south of the TN Valley. A weak trough axis at the surface was moving southeast through MO with a weak ridge following behind. The trough basically becomes ill-defined tonight with the ridge becoming more merged with the high over the Gulf.
1020 AM MST Wed Nov 12 2025 - Warmer than average temperatures (5 to 15 degrees) and dry conditions continue through Thursday.
700 PM EST Wed Nov 12 2025 - Gradual warming as high pressure settles over Florida, but a few cool mornings remain in store through the weekend. Winds have relaxed, veering from west to northwesterly up north to northerly down south at 5 to 10 mph around the high.
652 PM EST Wed Nov 12 2025 High pressure will hold over the Mid South and Southeast through the rest of the week. High pressure will remain over the deep south through tonight. A weak Appalachian surface lee trough will exist in the overall WSW flow. Trended forecast on the cooler side of guidance and results in mainly in the 30s areawide (warmest in urban areas). Pockets of sub-freezing temperatures across the rural Piedmont will be possible.
723 PM MST Wed Nov 12 2025 - Warmer than average temperatures (5 to 15 degrees) and dry conditions Thursday.
Thus, made some adjustments to hourly temperature trends this evening to show the cooler trend, which ultimately resulted in lowering overnight lows and is more closely aligned with MOS guidance. This should put overnight lows in the low 40s across the Nature Coast with low/mid 40s for interior areas and low/mid 50s for coastal areas from Tampa Bay southward.
342 PM MST Wed Nov 12 2025 - Warmer than average temperatures (5 to 15 degrees) and dry conditions today and tomorrow.
604 PM EST Wed Nov 12 2025 Warming trend through the week with high pressure in control.
640 PM EST Wed Nov 12 2025 High pressure keeps dry conditions in place through the weekend. Key message(s): - None Winds continue to diminish this evening as the pressure gradient relaxes ahead of building high pressure.
This afternoon satellite and model analysis showed the Great lakes under northwesterly flow aloft with an upper level low over Labrador and upper level ridging over the intermountain west. Some snow could mix in overnight for inland areas but little if any accumulation is expected with temperatures remaining above freezing. P expect sunshine with temperatures moderating into the low to mid 40s across the U.
pdf - Extended Dry Spell through Weekend Creating Fire Weather Concerns No major updates needed this evening, some minor adjustments to the low temperatures tonight due to good conditions for radiational cooling. (Through Tonight) A weak southeast moving cold front will pass to the north of the area this afternoon and evening. High pressure ridging will remain in place across area through the night. The center of the high Tonight will be just to the west of the area, providing a light west/southwest flow.
This is in response an approaching upper level trough and southwest flow aloft that will keep mountain showers through the day today before becoming widespread Thursday as the trough and associated frontal system pass through the Pacific Northwest.
With surface ridging and light winds, combined with seasonably warm lows, 4F to 10F above (44F to 55F), some radiational fog may be possible overnight. /DC/ Upper-level ridging will prevail over the western and central Gulf Coast region through the end of this week. Overall trends with the model guidance continue to show upstream weather pattern will dig trough farther west this weekend.
221 AM EST Thu Nov 13 2025 - Trending warmer through the remainder of the week.
1210 AM EST Thu Nov 13 2025 Unsettled weather remains in place today as upper level low pressure continues to move overhead.
936 PM MST Wed Nov 12 2025 - Warmer than average temperatures (5 to 15 degrees) and dry conditions Thursday.
1204 AM EST Thu Nov 13 2025 - Gradual warming as high pressure settles over Florida, but a few cool mornings remain in store through the weekend. Winds have relaxed, veering from west to northwesterly up north to northerly down south at 5 to 10 mph around the high.
1240 AM EST Thu Nov 13 2025 High pressure will hold over the Mid South and Southeast through the rest of the week. All in all, expect fair and dry weather today with seasonable high temps within a few degrees of normal, from the low 60s N to around 70 S. Lows should be a little cooler than this morning, 33-40 as the low levels decouple and winds abate toward nightfall. High pressure will hold to our W and SW, while in the mid levels, we'll stay in a generally NW steering flow but with a slight veer to NNW as mid level low pressure deepens over the Canadian Maritimes.
Winds will likely become gusty by the afternoon as a Lee cyclone develops to the west, tightening the surface gradient.
Through tonight: Continued dry and warmer than normal through the period. There will be a few more clouds around today than there were yesterday but temperatures will top out nearly ten degrees warmer than normal in the mid to upper 70s over most of the CWA. Tonight a stronger >1024mb high to our northeast will ridge back to the southwest across our CWA.
- One More Warm Day: Today will be unseasonably mild before a cold front arrives tonight. - Active, Unsettled Pattern: A change in the weather pattern will bring cooler temperatures and chances for precipitation, starting tonight and continuing through the weekend. Outside of the fog, high pressure will give us one more unseasonably mild day, with high temperatures running 10 to 15 degrees above average for mid-November. The main weather story changes tonight as a cold front moves into the region from the Pacific Northwest.
