(Tonight through Wednesday Night) An upper level low will slowly move east early Tuesday as weak short wave ridging builds in. Drizzle should dissipate as the morning goes on but the low clouds will stick around throughout the day. Weak southerly flow will warm things up a little bit tomorrow but the low clouds will also limit some of the warming, highs should be in the low to mid 60s. The rain will become more showery during the afternoon and evening on Wednesday with showers lingering into Wednesday night as the upper level low stays over us. As the low deepens Tuesday night we will see southerly winds amp up and wind gusts to 25 mph will be possible through mainly Wednesday morning. Highs Wednesday will remain cool in the low to mid 50s.
- Much cooler temperatures and gusty winds today. WV imagery indicates a deepening upper level trough of low pressure digging southeast through the Central Plains. Near the surface, a strong cold front is pushing southeast through south central Kansas into northern Oklahoma. Otherwise, the SREF indicates the upper level trough evolving into a closed low as it digs farther southeast through the Central Plains today and into the Deep South later tonight, giving way to a north-northwest flow aloft across the Western High Plains. Unseasonably cool temperatures are forecast today as cooler air surges southward through western Kansas, lowering H85 temperatures near to just below 5C by this afternoon.
636 AM EDT Tue Oct 28 2025 - A strong cold front is forecast to move through on Wednesday with the coldest temperatures of the season so far in its wake.
- A strong cold front will move through the region tonight and bring the next best chance for rain. - Strong gusty winds are expected Wednesday in the wake of the cold front. A steep ridge to trough upper-level pattern is set up from the West Coast to the Central Plains to start the period, with a 100+ knot jet angling from British Columbia/Alberta toward the Deep South heading into the daytime. A low pressure system will quickly develop at the base of the trough tonight into Wednesday morning. Resulting flow will bring a cold front and showers or storms through our forecast area primarily between about 6 PM this evening through 1 AM Wednesday morning. Strong cold air advection in the wake of the cold front and flow around the upper-level system will keep the boundary layer mixed and saturated.
546 AM CDT Tue Oct 28 2025 - A cold front moves across the area today bringing much cooler, below average temperatures tonight into the weekend. Attention for the rest of the day turns to the highly anticipated cold front which will move across South Central Texas during the daytime hours. Winds will quickly pick up behind the cold front today with sustained northerly winds from 15-25 mph and gusts as high as 30 to 40 mph.
310 AM PDT Tue Oct 28 2025 Offshore flow and strengthening high pressure aloft will bring warming through Wednesday with periods of gusty Santa Ana winds along and below the coastal slopes of the mountains through Wednesday with the stronger gusts to 35 to 45 mph today.
728 AM MDT Tue Oct 28 2025 KEY MESSAGES: - A ridge is building over the region today. A ridge of high pressure is building over the region today.
Pops continue to be tweeked as west edge of an enhanced rain band continues to move north and a bit west as bottom edge of 500 mb short wave trough moves into the southern RRV and took the rain a bit more west. 500 mb shows the 500 mb short wave lifted into southern Manitoba with an elongated short wave trough south thru the RRV. Main rain area is east of the 500 mb short wave trough over Minnesota and light rain will continue to advance north ahead of this slow moving short wave trough thru the day, eventually moving out of the far eastern fcst area late this evening as system hits the upper high over eastern Ontario and dries up as a separate 500 mb system develops and intensifies over Arkansas thru today.
- Reinforcing cool, dry air moves in late week behind a stronger cold front. Most noticeable will be the cooler temperatures with afternoon highs holding in the 70s on Thu-Sat with Fri being the coolest day in the low to mid 70s areawide which will be 10 degrees below normal.
Breezy northeast winds and slightly cooler temperatures are expected along and south of the Mogollon Rim today through early Wednesday. High pressure will be the name of the game over the coming week.
523 AM MDT Tue Oct 28 2025 - Chilly today with temperatures struggling to reach the lower 40s. - High pressure bring moderating temperatures through the rest of the week, with highs in the 50s and 60s. The H5 trough is quickly departing to the east taking cloud cover and precip with it. Cold temperatures will remain entrenched across the state, keeping temperatures much cooler than we've seen recently, only reaching the lower 40s for most areas. The rest of this week will be dominated by the building H5 ridge across the Rockies.
With a weak ridge moving over the area, dry conditions will continue and temperatures will warm across the area today. A weak front will follow the ridge, arriving late tonight into early Wednesday morning.
- A cold front brings cooler temperatures, gusty winds, and increased rain chances Tuesday night and Wednesday. A strong cold front looks to move through the area Tuesday night into early Wednesday morning, allowing low temperatures to drop into the mid 50s to low 60s.
This is in part thanks to zonal flow giving way to a building ridge along the West Coast and persistent light offshore flow across the region. Offshore flow typically brings in warmer and drier air which will help to suppress fog and low level cloud development this morning and keep morning temperatures warmer than they were yesterday. This change in temperatures is most notable across the higher elevations where temperatures are running around 10 to 14 degrees Fahrenheit warmer tonight than they were at this time yesterday. Morning low temperatures will generally be in the upper 40s to low 50s with portions of the interior Central Coast reaching the low to mid 40s.
-A cold front will usher in relatively cooler, drier, and breezy conditions for the middle of the week. Fairly benign sensible weather conditions will continue today, but northeast to east breezes will gradually increase while backing to the north as surface ridging strengthens. As the pressure gradient between the ridging and Major Hurricane Melissa tightens, breezes will continue to increase as we head into the middle of the week.

Beneath the ridge, a mid-upper low off the coast of Maine is forecast to retrograde toward the eastern Great Lakes and phase with a weaker mid-level low currently over eastern TN/KY. While we manage to stay mostly dry on Wednesday, the local area will remain in between deepening low pressure across the mid- Mississippi Valley and high pressure over eastern Canada.
- Warmer temperatures return late this week and for the weekend. Current KCYS radar loop shows snow and rain shower activity coming to an end early this morning as the progressive upper level trough axis has pushed southeast of the forecast area into the high plains. Areas along and west of the I-25 corridor received a dusting to half inch of snow, enough to make the higher elevation roadways icy. This snow will taper off here shortly with decreasing cloudiness behind the trough axis, due to increasing low to midlevel subsidence. In this pattern, high temperatures will struggle to reach 40 degrees for most of the area, with low to mid 30s for the high valleys west of the Laramie Range and teens/20s for the mountains.
- Rain returns to the area on Tuesday ahead and along a cold front. - Expect gusty winds and cooler temperatures behind the front on Wednesday, with dry and cool conditions continuing through the remainder of the week. An upper-trough will push a cold front across the region on Tuesday.
Cooler temperatures are forecast Tuesday night into Wednesday morning. Our latest low pressure system has been moving over the CWA early this morning. Tonight, we will see a weak ridge build in from the southwest, keeping the sky clear. There is a 20% chance winds overnight keep the boundary layer mixed and temperatures remain 5 degrees warmer than currently forecast. Wednesday, the ridge builds in farther.
900 AM MDT Tue Oct 28 2025 - Chilly today with temperatures struggling to reach the lower 40s. - High pressure brings moderating temperatures through the rest of the week, with highs in the 50s and 60s. With high pressure building quickly in behind the trough that brought gusty winds and snow to the region through Yesterday evening, the quiet weather will continue through the rest of the week. The H5 trough is quickly departing to the east taking cloud cover and precip with it. Cold temperatures will remain entrenched across the state, keeping temperatures much cooler than we've seen recently, only reaching the lower 40s for most areas. The rest of this week will be dominated by the building H5 ridge across the Rockies.

230 PM CDT Tue Oct 28 2025 - A strong cold front will move through the region tonight and bring the next best chance for rain. - Strong gusty winds are expected Wednesday in the wake of the cold front. Through Wednesday night: Latest surface analysis had a 1010mb low centered over northeast Texas with a warm front stretching across northern Louisiana and into our delta region. Local radars showed showers and thunderstorms along and north of the warm front. In addition, models suggest the possibility of a stinger jet rounding the closed low.
A few pockets of fog/stratus in mtn valleys this morning, otherwise a cold and clear start with widespread sub- freezing temperatures.
-A cold front will usher in relatively cooler, drier, and breezy conditions for the middle of the week. Synoptic analysis places a weak cold front approaching the southeastern Gulf, with tremendous dry air in its wake detected in satellite-derived total precipitable water products. GOES visible satellite imagery is highlighting mostly sunny skies outside of any isolated showers dotting the CWA, with land-based sensors detecting temperatures generally in the lower to mid 80s. Fairly benign sensible weather conditions will continue today, but northeast to east breezes will gradually increase while backing to the north as surface ridging strengthens. As the pressure gradient between the ridging and Major Hurricane Melissa tightens, breezes will continue to increase as we head into the middle of the week.
Highs today will end up in the lower to mid 50s, cooling into the mid to upper 40s by daybreak Wednesday. Northeasterly winds remain breezy at times this afternoon, making it feel even cooler outside.
Cold front and shower band are moving over the mountains, and onto the plains north of Denver, an hour or two ahead of schedule. The faster timing also means the end of the showers and clearing should be a bit faster, down to a few ridgetop flurries and showers exiting the eastern border areas by midnight. Tuesday will be quite a bit cooler. The NAM is curiously cooler and its MOS guidance seems 5-10 degrees cooler than what model soundings would support. It will be a little below freezing in most of this area tonight, and then colder on Wednesday morning. This combined with light winds and a cool airmass will lead to subfreezing temperatures Tuesday night and into Wednesday morning.
