This high will also bring in slightly drier air which will lower relative humidity (RH) values down to around 30%. Light and variable winds are expected this evening and night as the center of the high passes through the area. This will allow low temperatures to fall down to the 30s to up to the low 40s across south central South Dakota tonight. Upper level ridging continues to build across the southwestern CONUS. While the center of the ridge will remain in this area, the ridge axis will extend up to the international border, remaining mainly along the Rocky Mountains. This will place the Northern Plains downstream of the ridge and in an area of upper level subsidence. High temperatures will rebound to the upper 60s to the 70s and 80s beneath the ridge.
(Tonight through Monday night) Upper level ridging will keep conditions quiet today with dry weather and mostly sunny skies. Temperatures continue to be coolest in the southern Edwards Plateau and Hill Country each night with lows in the in the low 60s for these locations.
1232 PM CDT Sun Oct 6 2024 - Slightly cooler today due to weak frontal passage - Well above average high temperatures and mostly dry conditions will continue through this week. (Today through Monday night) Cold front which is currently just entering the far NW Panhandles will be surging across most of the area through 18 UTC, but will put on the brakes just south of the area given the parent upper trough will move across the great Lakes region well NE of the area.
A cooler and drier airmass is in place behind last evening's cold front and temperatures are much more seasonable today, topping out in the mid to upper 70s. Northwest flow remains in control of the region through the week with the mid-level ridge confined to far southwest US and northern Mexico.
Water vapor imagery currently shows northwesterly flow aloft over the Middle Mississippi Valley on the backside of a trough digging into the northeastern CONUS. Surface observations show that the cold front has cleared the CWA to southeast, with dew points dropping gradually areawide. Tonight, high pressure will edge into the area, causing winds to weaken and skies to remain clear. Most locations should see temperatures bottom out in the low to mid 40s, with some areas in northeastern MO and the Ozarks seeing values dip into the upper 30s. With the post-frontal airmass further entrenched over the region tomorrow, temperatures are expected to be cooler relative to today. The result is most locations seeing afternoon temperatures top out in the low 70s - right around climatological normals.
Overall, the forecast remains well on track with the upper ridge and weak disturbance pushing east.
In the upper levels the closed low over Ontario Canada continues to shift eastward and behind this ridging builds once again across the area through the work week. At the surface, high pressure also builds across Kansas and slides over northern Missouri and Iowa on Monday.
High pressure prevails across the western CONUS today. High pressure continues to dominate across the region throughout the upcoming week with the CWA staying in the northern fringe.
While Hurricane Milton has formed in the southern Gulf and is poised to move eastward towards Florida over the next several days, the big weather maker for us will be a strong cold front that is currently moving into far Northwest Arkansas. Did trend temps a little cooler overnight across our far northern zones but kept temps pretty much unchanged from NBM #s near and south of the I-20 Corridor given that the front will likely not make it to the corridor by sunrise vs what progs were suggesting yesterday.
215 PM CDT Sun Oct 6 2024 Weak ridging aloft will remain wedged into the region from the west. A closed mid/upper level low pressure system currently moving east across Ontario Canada, will continue to move east across southern portions of Hudson Bay into Quebec through Monday. Highs on Monday will range from the lower 80s north, where cooler air will begin advecting into the area behind the aforementioned cold front, to around 90 in the south ahead of it. In addition, with high pressure surging into the area in the front's wake, and what's now Hurricane Milton moving northeast across the central Gulf of Mexico, the pressure gradient will begin tightening across the region Monday.
1141 AM EDT Sun Oct 6 2024 High pressure will cross the region today. A cold front will begin to approach later tonight, then slowly cross the region Monday while low pressure tracks along the front.
(This evening through Monday) Little change to our weather the next 24 hours, as we remain under the influence of high pressure aloft. (Monday night through next Sunday) Upper level ridging will result in above normal temperatures and dry conditions across West Central Texas through this week.
The cold front has moved through much of the area today, but without much colder temperatures, at least initially.
1215 PM CDT Sun Oct 6 2024 - Breezy and very dry conditions will develop behind a cold front this afternoon, bringing elevated fire danger to areas north of Interstate 70 where there is a 20-50% joint probability for gusts greater than 25 mph and RH values less than 25 percent.
Short term forecast will focus on the return to above normal temperatures and dry weather for the foreseeable future, with a flat upper level ridge remaining firmly in place across the Intermountain West and High Plains.
/NEW/ /Through Tomorrow/ The weather across North and Central Texas will remain hot and dry through the next several days, even in the wake of a cold front that will arrive later today. This rather stagnant weather pattern is due to ridging across the southwestern CONUS, deflecting weather systems well north and east of our region. This evening's cold front will arrive without much fanfare given a lack of precipitation and no significant cooling the next few days. Temperatures tomorrow will likely only be 2-3 degrees cooler compared to today with light northerly winds continuing.
That front will be ushering in a cooler and drier air mass for the remainder of the work week.
A dry cold front has pushed through much of the area during the morning and early afternoon hours, bringing slightly cooler temperatures and shifting winds out of the north. Observed temperatures have been a few degrees cooler than yesterday, with temperatures in the upper 70 to low 80 degree range. As the afternoon progresses, temperatures will climb, ranging in the low to upper 80s, with the higher end of that range towards the MO/AR border.
The sunny and warming trend will peak on Monday as a trough works its way southward from B.
A ridge will begin to build in into the work week, causing well above normal temperatures mid-week for October. If you're wondering if we can at least expect some cooler nights, unfortunately, our chances of seeing temperatures below 32 degrees this week are less than 10%. With the ridge, chances of appreciable QPF this week are near zero as well.
1217 PM CDT Sun Oct 6 2024 (Today through Monday afternoon) WV imagery this morning still shows a weakness in the upper ridge in the form of an inverted trough that is having little effect on West Texas and Southeast New Mexico other than keeping highs a bit cooler each day than they otherwise would be. That said, highs this afternoon should be very similar to yesterday's, if not a degree warmer at ~ 7-9 F above normal. A cold front will approach the area but, like the last one, looks weak.
An upper- level low pressure system will approach the coast on Monday which could lead to a slight chance of afternoon and evening showers in the highest elevations of the Sierra Nevada.
(Tonight) Cold front will make steady progress southward through the local forecast area this afternoon through the early morning hours. Guidance continues to indicate several periods through mid week where mid level moisture will deepen on the periphery of the upper ridge and spread in or near the local region. While confidence may be trending upward in this occurring, the low coverage and variable placement will keep precip chances very low at this time. (18Z TAFS) Weak cold front moving across northeast OK and northwest AR may result in periodic N wind gusts approaching 20 knots.
203 PM EDT Sun Oct 6 2024 Warm and dry conditions persist until a cold front tracks across the region Monday.
This will be the last in a string of climatologically warm days for early October, as a secondary cold front will near the area overnight. Expect the cold front to be making its way through the Tennessee Valley as you head out for the morning commute.
Temperatures are currently running in the mid 60s to lower 70s across the lower elevations, with just a couple of degrees warming possible through this afternoon. Highs tomorrow will reach through the 70s to lower 80s for the lower elevations.
* Later this week a Pacific Northwest trough will bring a cooling trend that will bring near average temperatures with increased breezes and low chance for rain.
Breezy northeast winds were common in the wake of a cold front with northwest mid/upper flow observed across the central CONUS.
1034 AM PDT Sun Oct 6 2024 Quiet weather is expected through the middle of the week as high pressure builds into the Pacific Northwest.
Although upper level ridging will remain in place for Monday, a weak trough will be moving out of the Rockies onto the Central Plains. This will cause weak surface cyclogenesis in lee of the Rockies with a pressure trough extending southward into eastern New Mexico. The aforementioned upper ridge will weaken a bit on Monday leading to slightly cooler temperatures but still on the order of five to ten degrees above seasonal averages.
226 PM CDT Sun Oct 6 2024 - A cooler sunday (highs in the 70s) before the week warms back up to the 80s. A subtle ridge has built over the Rockies aloft with high pressure systems at the surface. Ensembles have the ridge and associated high pressures slowly moving east over the next couple days. After the recent cold front passage, highs today are forecasted to be much cooler than the last few days with nearly all of SW Kansas staying in the mid 70s. The weather the next few days will be homogeneous as the weak ridge and high pressures reach over the forecast area.
143 PM MDT Sun Oct 6 2024 Upper level ridging will keep the region mostly warm and dry through the week.
A cold front approaches tonight and will cross through Monday morning. High pressure presently sits to our north, yielding clear skies for most with some fair weather clouds developing over southern and eastern New Jersey. The cold front currently crossing the Upper Midwest and western Great Lakes will enter our region tonight and clear us on Monday morning.
1043 AM MDT Sun Oct 6 2024 - Cooler temperatures (highs in the 70s) expected today. Sunday will be a bit cooler thanks to CAA behind yesterday's cold front as the ridge builds back over the area both aloft and near the surface. Brief gusts of 20- 25 mph will be possible this afternoon primarily west of the Colorado border and south of US-40 in Western Kansas Overnight lows will be in the low to mid 40s. With a warm front setting up along the Colorado border, winds behind the front will become northerly with gusts to 25 mph while those ahead of the front will have southerly to southwesterly winds gusting to ~20 mph. Given the low confidence conditions occur, we have held of for now on any fire weather related hazard products.
211 PM EDT Sun Oct 6 2024 A few showers and thunderstorms will be possible this afternoon into early evening in eastern parts of the area as a cold front moves through the region. Dry conditions will return for the remainder of the upcoming week as high pressure builds across most of the United States. Associated relatively strong surface cold front currently pushing across Indiana to drop east-southeast across the area this aftn. Pressure gradient tightens with good low level moisture advection ahead of the front - with dewpoints in the lower to mid 60s. This will yield to dry conditions area-wide of the remainder of the short term period as drier air and high pressure settle into the region for the start of the workweek.
The warmest temperatures of the forecast period are expected on Monday as an upper level ridge becomes positioned over the northwest. The ridge will transit east on Monday evening, for a trough and front to arrive and keep rain showers in the forecast through mid week.
1227 PM CDT Sun Oct 6 2024 - Elevated fire weather conditions today with breezy winds and very dry air behind a cold front. A dry cold front will move through this morning, bringing somewhat cooler conditions and much drier air to the area.
319 PM EDT Sun Oct 6 2024 - Some clouds and turning cooler tonight - High pressure brings quiet weather Monday and Monday night - Cool and dry, then warmer with showers possible - Some clouds and turning cooler tonight Winds will remain strong for the next several hours and begin to diminish as we approach sunset due to the loss of daytime heating and correspondingly mixing. It will be a cool night with lows mainly in the lower to middle 40s. - High pressure brings quiet weather Monday and Monday night High pressure begins to move in on Monday which should trend conditions back to mostly sunny and calm the wind down as well.
Mid level WV and 500mb analysis depicts building ridge over the western US with the upper level low churning off to the east. Upper ridge will continue to build into the region through tomorrow into this week, tilting from north-south to northeast- southwest. Low- level thermal ridge will develop as the upper ridge remains overhead, bringing above average temperatures back into the region.
Drier air associated with this high will move into the area tonight. Temperatures are expected to remain in the low 40s to upper 30s, however dewpoints are forecast to be in the low 30s. This high will drive the weather tomorrow as well with highs in the 60s areawide. Another beautiful start to work week with lower humidity and cooler temps.
1246 PM CDT Sun Oct 6 2024 (Today through Monday Night) High pressure will continue to build in from the north through the short term period, and this will result in both increased deep layer subsidence and drying throughout the atmospheric column. The dry airmass will also support a fairly large diurnal range with highs easily climbing into the mid to upper 80s and even into the lower 90s around Baton Rouge both today and tomorrow, but lows will cool into the upper 60s and lower 70s tonight and even fall further into the upper 50s and low to mid 60s by tomorrow night.
1140 AM MDT Sun Oct 6 2024 - High pressure will keep dry conditions in the forecast with near record-highs expected.
(Rest of today through Monday) A cold front is poised to sweep across Middle Tennessee during the next several hours. Westerly winds will be around 5 to 10 knots during the day today, becoming northwesterly after 00Z and northerly around 06Z as a cold front moves through the area.
Dry and milder conditions are expected on Monday, following the passage of a cold front. This Evening/Tonight Currently this afternoon, a closed low is centered north of the Great Lakes with a cold front progressing towards the Ohio River Valley. With pretty weak support and strong high pressure to the west, this development will likely be limited. Monday By late Monday morning, the cold front is expected to have moved south and east of our area with expansion of high pressure from the Great Plains.
Freezing temperatures are unlikely (only a 5% chance in Ord, per NBM), but some areas north of I-80 could see frost develop in low-lying areas. Increased ridging aloft will allow temperatures to trend back into 80s by the middle of the week. There will be some weak perturbations under the ridge, but the lack of moisture should keep the region dry.
1200 PM CDT Sun Oct 6 2024 (Rest of Today) Early morning fog has since dissipated over the area, as high pressure continues to promote warm and dry conditions over the Southeast. A stalled frontal boundary will keep the richer Gulf moisture locked closer to the coastal region, while a second cold front nears the area from the northwest later today. Temperatures will remain on the warmer side of climatological norms, topping out in the upper 80s to lower 90s this afternoon.
234 PM MDT Sun Oct 6 2024 - Cooler temperatures (highs in the 70s) expected today. the center (ridge) of which extends northward from the northern Rockies to the Northwest Territories and Nunavut. Meanwhile, at lower latitudes (25-35N), an active southern stream jet in the Pacific will usher a positively tilted trough ashore the southern Pacific Coast /Baja, CA/ Mon- Mon night. will back to the west Mon-Mon night as the aforementioned southern stream trough progresses ashore the southern Pacific Coast. Upper ridge moves little through the week with dry conditions and above normal temperatures.
1212 PM CDT Sun Oct 6 2024 Weak cold front approaching OK/KS border this morning, and should push into northeast OK a little after Noon, and approaching I-40 by early this evening. (Today) A cold front will move south across the area this afternoon and evening.
(This evening through Monday) One more day of widespread Moderate to Major HeatRisk with isolated areas of Extreme HeatRisk in the higher elevations across the region. Tonight, temperatures are expected to remain very warm in the region's higher elevations with 70's to mid 80's expected while the valleys and coastal areas cool into the low-to-upper 60's.
1101 AM CDT Sun Oct 6 2024 Weak cold front approaching OK/KS border this morning, and should push into northeast OK a little after Noon, and approaching I-40 by early this evening. (Today) A cold front will move south across the area this afternoon and evening.
310 PM EDT Sun Oct 6 2024 (This afternoon through Monday) At a glance: - Warmer than average - An isolated shower possible along/south of Columbus A stationary boundary draped across the northern Gulf will allow for a few showers to continue across our far southern tier this afternoon, primarily along and south of a line extending from Columbus to Macon, otherwise yet another dry day on tap.
1140 AM MDT Sun Oct 6 2024 Updated Aviation Discussion Upper level ridging will keep us warm and dry through most of this week, with temperatures closer to what you would expect in early September instead of early October.
This should allow for cooler temperatures in the mid 50s for southeast New Mexico and the northwestern Permian Basin.
1231 PM CDT Sun Oct 6 2024 (Rest of today through Monday) A cold front is poised to sweep across Middle Tennessee during the next several hours. A dry cold front will move through the terminals overnight causing winds to shift to the north and bring some scattered mid level clouds.
Overnight, lows are expected to dip into the lower 30s prompting some frost headlines once again. The high pressure over the Midwest shifts east by midweek with thermal ridging building back into the region.
348 PM EDT Sun Oct 6 2024 A few showers and thunderstorms will be possible into early evening in eastern parts of the area as a cold front moves through the region. Dry conditions will return for the remainder of the upcoming week as high pressure builds across most of the United States. Associated relatively strong surface cold front currently pushing into west central Ohio to drop east-southeast across the area this aftn. Temperatures will be considerably cooler with highs in the mid and upper 60s. High pressure parks over the Ohio Valley for most of the upcoming week.
228 PM MDT Sun Oct 6 2024 - High pressure will keep dry conditions in the forecast with near record-highs expected.
147 PM EDT Sun Oct 6 2024 Above normal temperatures and mainly dry weather are expected through Monday as high pressure dominates. A cold front should move through Monday night with a few showers possible before high pressure brings cooler and drier weather for most of the week. Breezy conditions and hazardous marine and surf conditions possible mid week as tropical cyclone Milton likely brushes the area. Cooler and drier weather then on tap late in the week. Weak high pressure will remain situated across the area through the near term forecast period.
Lows tonight ranging from the low to middle 60s over most inland locations, upper 60s to around 70 at the coast.
240 PM CDT Sun Oct 6 2024 - Breezy and cooler conditions are expected today. Increased diurnal mixing, the tighter pressure gradient between the low pressure system to the northeast and high pressure to the west, and the secondary cold front have all worked together to bring gusts to 30 to 35 mph at times. This evening into tonight the low pressure system will continue to pull off to the northeast and high pressure will begin to build in resulting in weakening winds. Dry and mostly clear skies are expected to continue into the work week as high pressure builds into the Great Lakes Region. Patterson Issued 340 PM CDT Sun Oct 6 2024 Monday night through Sunday: The Great Lakes Region is expected to remain under the effects of high pressure through most of the week.
602 PM CDT Sun Oct 6 2024 - A cooler sunday (highs in the 70s) before the week warms back up to the 80s. A subtle ridge has built over the Rockies aloft with high pressure systems at the surface. Ensembles have the ridge and associated high pressures slowly moving east over the next couple days. After the recent cold front passage, highs today are forecasted to be much cooler than the last few days with nearly all of SW Kansas staying in the mid 70s. The weather the next few days will be homogeneous as the weak ridge and high pressures reach over the forecast area.
Lows tonight ranging from the low to middle 60s over most inland locations, upper 60s to lower 70s at the coast.
603 PM CDT Sun Oct 6 2024 (Tonight through Monday night) Upper level ridging will keep conditions quiet today with dry weather and mostly sunny skies. Temperatures continue to be coolest in the southern Edwards Plateau and Hill Country each night with lows in the in the low 60s for these locations.
1041 PM EDT Sun Oct 6 2024 There will be a chance for some passing showers and isolated thunderstorms overnight, as a cold front moves through the area. Behind this front, cooler air will move into the region during the upcoming week, although it will continue to remain dry for most of the time. We retooled the PoPs and weather for the next 3-6 hours with the pre-frontal showers and thunderstorms and then the cold front towards sunrise.
This will force a cold front into the northern portions of Alabama by sunrise. At the same time the inverted trough in place will slide to our west and wash out.
625 PM CDT Sun Oct 6 2024 Weak ridging aloft will remain wedged into the region from the west. A closed mid/upper level low pressure system currently moving east across Ontario Canada, will continue to move east across southern portions of Hudson Bay into Quebec through Monday. Highs on Monday will range from the lower 80s north, where cooler air will begin advecting into the area behind the aforementioned cold front, to around 90 in the south ahead of it. In addition, with high pressure surging into the area in the front's wake, and what's now Hurricane Milton moving northeast across the central Gulf of Mexico, the pressure gradient will begin tightening across the region Monday.
High pressure will bring mainly dry and warmer weather for today and Monday.
A decent temperature gradient still looks to take up residence tomorrow (Monday) with forecast highs in the low 60s further North due to quicker clearing and mid 50s further south.
214 PM EST Sun Feb 4 2024 High pressure and upper level ridging dominate the weather pattern through midweek with dry conditions expected.
As upper level ridging moves in through the day, we'll see the clouds from overnight begin to dissipate, leaving mostly sunny skies by late afternoon. (Monday night through next Sunday) An upper-level ridge looks to build in across the southern Plains for the start of the work week.
