407 AM MST Mon Nov 8 2021 Latest surface analysis shows cold front has pushed across most of northeast Colorado early this morning. We'll be left in a cooler, post-frontal environment today, likely shaving off about 20 degrees from yesterday's near record warmth. Latest model trends have shown the airmass to be a little cooler and deeper, and we expect a gradual increase/thickening of high level cloudiness. Mountain areas will see less cooling, on the order of 5 to 10 degrees from the highs observed yesterday. Skies should clear sufficiently later tonight to allow lows to drop below freezing in most areas. Mid and upper level moisture will increase from west to east ahead of the trough by the afternoon. A Denver cyclone, may help to keep slightly cooler temperatures west and north of Denver.
High clouds will increase this afternoon into tonight, while a weak cold front will approach from north late. Temperatures will peak in the lower to middle 80s for most locations, even a few upper 80s where downslope flow is maximized over eastern Briscoe, Hall and northern Motley Counties. Current NWP suggest the cold front will edge into our northerly zones around 09- 12Z Tuesday. It will be cooler Tuesday, with Highs ranging from low 70s north to near 80 south, about a 10 degree cool-off across the north.
/issued 237 AM CST Mon Nov 8 2021/ An anomalous ridge will build over the Mid-South through today with 500 mb geopotential heights increasing up to 588 dam (97th percentile of climatology). This will result in above normal temperatures across the CWA the next few days with southerly flow resuming as the surface anticyclone finally shifts to the east. A deep trough is taking shape in the western CONUS at this time and will eventually lead to our next rain chances as a late week cold front moves across the Mid-South.
209 AM MST Mon Nov 8 2021 The overall weather pattern will be unsettled, cooler, and windy this week (compared to last week), with periodic chances of rain/snow.
532 AM CST Mon Nov 8 2021 Aside from a bit of cirrus to our west, latest observations show clear skies across the region, in addition to northwesterly winds and temperatures in the low 40s. Should see largely quiet conditions prevail Tuesday, with temperatures forecast to be a touch cooler than Monday, despite winds becoming easterly/southeasterly.
622 AM EST Mon Nov 8 2021 Dry and warmer weather can be expected under high pressure for the first half of the week. Rain is expected to return with a late week cold front.
320 AM CST Mon Nov 8 2021 Aside from a bit of cirrus to our west, latest observations show clear skies across the region, in addition to northwesterly winds and temperatures in the low 40s. Nonetheless, will certainly be cooler than what we experienced this weekend. Should see largely quiet conditions prevail Tuesday, with temperatures forecast to be a touch cooler than Monday, despite winds becoming easterly/southeasterly.
The lower levels of the atmosphere remain quite dry so precipitation chances are non- existent for much of the area. Lift over this area comes from low-level convergence along the stalled surface front associated with the jet working in conjunction with a low amplitude mid-latitude trough arriving later in the day. Meanwhile, temperatures will remain mild, though afternoon highs are expected to be a bit cooler in response to cloud cover. Meanwhile, the stalled front to the north will be driven southward across the region as the trough moves overhead resulting in slightly cooler temperatures.
639 AM EST Mon Nov 8 2021 High pressure has settled over the region and will maintain dry weather through the middle part of the upcoming week.
Early morning analysis showed a surface cold front making steady progress southeastward across the area, which will mark the start of a cooling trend as we go through the work week.
410 AM EST Mon Nov 8 2021 High pressure will persist through Tuesday and as a result, expect dry weather to continue along with plenty of sunshine and above normal temperatures. Readings range from the low to mid 40s up north to low to mid 20s for our central and southern zones. Westerly flow aloft will advect in a weak disturbance which will lead to an increase in clouds towards Tuesday morning and drag a weak cold front across the area. Due to cloud cover and this front, temps on Tuesday will be a few degrees cooler than today but still above average in the low to mid 50s.
/Issued 1105 PM CST Sun Nov 7 2021/ /Overnight through Tuesday/ Mid level ridging will remain in place across the Southern Plains to start the week, keeping North Texas warm and dry with no significant weather to speak of. By late this afternoon, as broad troughing overspreads the western U. Clouds will overspread most of the region by Monday night, which will act to limit radiational cooling and should result in overnight lows about 5-10 degrees warmer than tonight.
Made some slight changes to the trends in temps and dewpoints through the afternoon, but did not change the highs or lows for temps. High temperatures will warm several degrees above normal this afternoon into the lower 70s for most areas. Given the dry atmospheric column, the lower end of guidance was favored for afternoon dewpoints.
Near the surface, a weak cold front is pushing southeast across southwest Kansas. A fairly quiet short term period with northwest flow aloft and high pressure extending across the CWA from the east. Mainly clear skies and light southerly winds will lead to mild morning low temperatures in the 40s ahead of a cold front approaching from the northwest. Behind the cold front expect winds to turn out of the north becoming a bit more breezy seeing winds around 10-20 mph throughout the afternoon and evening hours. Afternoon high temperatures will be cooler seeing mainly 60s with possible low 70s for far southeast counties depending on how quick the cold front pushes through south central Kansas.
Otherwise, mid level ridging over northeast Mexico will continue to provide subsidence across deep south Texas today through Tuesday. At the surface, high pressure across the Lower Mississippi River Vally this morning and is expected to slowly slide eastward through the period. Water levels will likely approach minor flood category again for the lower Texas coast this evening, with high tide at 9:19 pm.
335 AM CST Mon Nov 8 2021 High pressure at the surface and aloft will continue to slowly migrate east into the Appalachian Mountain chain today.
(Today and tonight) Surface observations early this morning indicate a cold front is slowly moving southward into NW KS.
317 AM CST Mon Nov 8 2021 A seasonably warm day is ahead with temperatures climbing into the low 70s across the area under a mostly clear sky and deep southwesterly flow.
/issued 346 AM EST Mon Nov 8 2021/ The upper-level pattern remains highly amplified in the wake of a rather strong area of low pressure that continues to move out to sea. As the ridge moves closer and the gradient relaxes, winds have begun to subside, moisture has continued to fade, and skies have cleared. As the high continues to propagate eastward, the winds are expected to shift accordingly. This gradual veering should lead to the eventual return of warmer air and, eventually as the winds transition to ESE, additional moisture.
639 AM EST Mon Nov 8 2021 Warm, dry high pressure will dominate the weather across the region through the middle of the week.
Cloud cover and cooler temperatures are in store for the rest of the region followed by dry and warmer conditions during the second half of the week as broad high pressure builds over the desert southwest. This is likely due to a bit faster translation of the upper low bringing the AR. 1 continues to show some very high wind gusts, that would push over High Wind Warning criteria (>70 mph) but only at the highest peaks.
851 AM EST Mon Nov 8 2021 Dry and warmer weather can be expected under high pressure for the first half of the week. Rain is expected to return with a late week cold front.
430 AM CST Mon Nov 8 2021 (Issued 427 AM CST Mon Nov 8 2021) Today through Tuesday: Today will be our last day in the 60s, as a cold front that is currently positioned from roughly Marquette, MI to La Crosse will slowly move southeast this morning and into the afternoon hours today. Expect highs in the low to mid 60s as a result. We'll remain on the cool side of the boundary with cloud cover overhead, and highs will be about 10 degrees cooler.
416 AM MST Mon Nov 8 2021 High pressure over the region with nearly zonal flow aloft this morning. Mild weather for early November is expected for today and Tuesday with the developing ridge and downslope flow.
There is a weak cold front (more of a wind shift line) in nw IA that will push slowly across the dvn forecast area later today. Tuesday, under clouds and a northeast wind, we have the potential to be much cooler than forecast.
Calm before the storm today with forecast focus on the approaching system for Tuesday as an organized trough of low pressure ejects inland from the coast.
542 AM EST Mon Nov 8 2021 Dry and warmer weather can be expected under high pressure for the first half of the week. Rain is expected to return with a late week cold front.
Another quite warm and pleasant afternoon is expected today with highs reaching the upper 60s to even low 70s across the area as mid level ridging remains in place. A cold front will slowly nudge its way southward into our area by later tonight, shifting winds from southerly to northerly and bringing ample cloud cover. Lows tonight will be a couple degrees cooler, but will remain well above normal thanks to cloud cover.
A sunny sky will be prevalent today with deep layer ridging and increasing thicknesses resulting. Highs should reach the lower 70s for all valley locations, with just a few upper 60s atop the highest portions of Lookout Mountain and the Cumberland Plateau areas. West-southwesterly flow aloft will return to the region later tonight and persist through Tuesday night, as an amplifying mid-level trough tracking east-southeastward from northern CA into the southern Rockies suppresses the subtropical ridge to our south.
Some of the high-res models and forecast soundings suggest patchy fog developing early Tuesday morning. High temperatures will again top out in the low to mid 80s w/the exception of the far eastern areas where higher dewpoints will keep highs in the 70s.
Temperatures will peak in the lower to middle 80s for most locations, even a few upper 80s where downslope flow is maximized over eastern Briscoe, Hall and northern Motley Counties. Current NWP suggest the cold front will edge into our northerly zones around 09- 12Z Tuesday. It will be cooler Tuesday, with Highs ranging from low 70s north to near 80 south, about a 10 degree cool-off across the north.
337 AM CST Mon Nov 8 2021 Weak cold front is making fast progress across the forecast area early this morning and will reach central Wisconsin by sunrise. With increased clouds and northwest winds, highs today will be several degrees cooler than what they were over the weekend, ranging from near 50 in central MN to the upper 50s for southern MN and western WI.
A weak cold front will bring a low chance for a few showers Tuesday into Tuesday night, along with slightly cooler air. 06z surface map indicated a high pressure ridge stretched from eastern TX into the Appalachians, while a low pressure trof extended from NW WI into the central Plains. This allowed light south to southwest gradient flow locally and 2 am readings several degrees warmer than previous mornings, in the mid/upper 40s. Aloft, upper ridging was nosing into the Great Lakes with southwest 500 mb flow prevailing across the Midwest. Highs likely a couple degrees warmer than yesterday and fall into a 65-70 degree range. Tonight the front slowly works into the northern CWA but lingering dry air behind the ridge precludes any pops. The increased cloud cover will keep highs a few degrees cooler in the low to mid 60s.
520 AM CST Mon Nov 8 2021 A seasonably warm day is ahead with temperatures climbing into the low 70s across the area under a mostly clear sky and deep southwesterly flow.
A gradual cooling trend takes place this week as high pressure diminishes.
417 AM CST Mon Nov 8 2021 Currently, temperatures are generally in the low 40s and falling gradually under a blanket of cloud cover. Dry conditions are expected on Tuesday, as high pressure drifts eastward.
High pressure will settle into the region for most of the week with pleasant weather expected. Current temperatures are in the upper 50's to low 60's and will slowly warm up into the low to mid 70's under sunny skies this afternoon. Broad high pressure has settled in over the southeast U. Winds decrease to around 10-15 knots by mid week as high pressure moves over northern Florida.
Precipitation has been generally light, however some local areas may reach the freezing mark this morning and create some slick spots in the Heron, Noxon, Troy and Libby areas.
Temperatures for tonight are expected to be slightly warmer as low level cloud coverage increases.
(Today and tonight) High pressure will keep warm and dry weather settled across the area for today and tonight. Otherwise, lows will be a bit warmer for tonight as they settle into the middle 50s tonight.
A patchy-areal coverage of fog is expected (mainly in river valleys and near large bodies of water), with a similar coverage of frost anticipated in southern TN where temps will be closer to freezing. Over the course of the day, the mid-level ridge noted above will shift southeastward across the local area, providing sunny and dry conditions. At the surface, a broad ridge of high pressure will remain centered over the TN Valley, with light/variable flow and no thermal advection allowing afternoon temps to warm into the lower 70s. West-southwesterly flow aloft will return to the region later tonight and persist through Tuesday night, as an amplifying mid-level trough tracking east-southeastward from northern CA into the southern Rockies suppresses the subtropical ridge to our south.
334 AM CST Mon Nov 8 2021 High temps well above normal and gusty winds will continue today ahead of a shallow cold front which is currently through NW KS.
South winds will develop Tuesday night and with the mixing lows will be 5 to 10 degrees higher than tonight in the low to mid 30s.
A closed upper low and deep troughing extends south through the western Atlantic. This ridging and high pressure is helping advect in some much cooler and drier air to the area through mid-week.
High pressure continues to build into the area beneath rising heights aloft. Thus, still looking like a nice and slightly warmer day amidst light vrb/sly flow.

1144 AM CST Mon Nov 8 2021 (Today and tonight) High pressure will keep warm and dry weather settled across the area for today and tonight. Otherwise, lows will be a bit warmer for tonight as they settle into the middle 50s tonight.
Big bubble means no trouble around here with strong high pressure firmly in control over the northern Gulf. Unfortunately, the ridge will slowly begin to flatten out by Tuesday afternoon with more zonal flow as the next system moves over the rockies.
This is due to strong warm air advection and very dry airmass ahead of a weak cold front stretched across northern lower Michigan into Wisconsin. Lows tonight will remain mild in the low to mid 40s. High pressure will quickly clear skies out Tuesday night allowing temperatures to fall into the 30s.
High pressure continues to build into the area beneath rising heights aloft. Thus, still looking like a nice and slightly warmer day amidst light vrb/nly flow.

An upper level ridge extends over northern Mexico and Texas with anti-cyclonic flow. The low level flow is from the southeast this afternoon. The upper ridge will progress across Texas tonight and Tuesday. The combination of warm advection and mostly cloudy skies will mean a much warmer morning Tuesday. Low temperatures will be near 10 degrees warmer than they were today. Tuesday night the upper pattern will begin transforming and a trough will move toward Texas. There will also be a cold front moving into West Texas. Ahead of this front the low level jet will increase across South Texas.
234 PM CST Mon Nov 8 2021 Generally zonal flow is present across a majority of the CONUS this afternoon, outside of a positively tilted upper trough over the East Coast. A vorticity maximum over the Upper Midwest has pushed a weak cold front southward, currently stretching from northeast to southwest across the forecast area. Temperatures have warmed into the low 70s to the south of this front, with mid 60s present to the north. While temperatures will be a bit cooler, the overall air mass will not be too much different behind the front.
328 PM EST Mon Nov 8 2021 High pressure will gradually build into the region through the middle of the week.
1026 AM MST Mon Nov 8 2021 The overall weather pattern will be unsettled, cooler, and windy this week (compared to last week), with periodic chances of rain/snow.
There's just enough lift in the low levels with moisture present that radar is picking weak echos across this area.
1103 AM CST Mon Nov 8 2021 Aside from a bit of cirrus to our west, latest observations show clear skies across the region, in addition to northwesterly winds and temperatures in the low 40s. Should see largely quiet conditions prevail Tuesday, with temperatures forecast to be a touch cooler than Monday, despite winds becoming easterly/southeasterly.
1025 AM MST Mon Nov 8 2021 The focus in the short term will be on the cooler and more seasonable temperatures expected through the middle of the week behind a cold front that is currently moving through the region early this morning.
SHORT TERM (Now through Tuesday Night): Quiet, slightly warmer than average but otherwise seasonal fall weather will prevail through the short term. Broad high pressure will shift a bit farther east but will still influence the CWA.
1217 PM EST Mon Nov 8 2021 Dry and warmer weather can be expected under high pressure for the first half of the week. Rain is expected to return with a late week cold front.
On the leading edge of the high pressure, an enhanced pressure gradient will keep our breezy winds going through sunset before weakening. Aside from any lingering sprinkles/flurries during the morning hours, Tuesday looks to remain fairly quiet as the high pressure continues to slowly slide eastwards resulting in northeasterly winds for areas west of I-29, and primarily easterly winds for areas east of I-29. Due to the high pressure remaining in the region and not seeing much sunlight until the afternoon, high temperatures tomorrow will be in the mid to upper 50s. There is some weak ridging that will be occurring during the afternoon hours, so it's possible temperatures end up being a touch higher into the lower 60s.
Surface winds in the the high teens earlier this morning are now 16 knots or less. From synopsis, a low pressure system located over the western North Atlantic will continue to push northeast away from the United States.
High pressure will lead to sunny/clear skies with above normal temperatures Monday and Tuesday. Discussion: Upper heights continue to rise across the eastern CONUS this afternoon as the Lower MS Valley H5 ridge axis extends northward into/through the OH/TN Valleys. At the surface, high pressure remains dominant and nearly centered atop the Southern Appalachians fostering light nly/vrb flow across east TN and southwest VA/NC, all amidst sunny skies. Otherwise, ample heating underway with temperatures pushing into the mid 60s for most areas, which will favor warmer overnight lows. On Tuesday, much the same as today as high pressure continues to dominate albeit with some suppression of the upper ridge axis given the passing northern stream trough across the Great Lakes.
1150 AM CST Mon Nov 8 2021 A seasonably warm day is ahead with temperatures climbing into the low 70s across the area under a mostly clear sky and deep southwesterly flow.
The increased cloud cover will result in a warmer night, with low temperatures ranging from the low 50s across the east to upper 50s across the west and in urban areas.
138 PM EST Mon Nov 8 2021 Dry and warmer weather can be expected under high pressure for the first half of the week. Rain is expected to return with a late week cold front.
116 PM CST Mon Nov 8 2021 At 18Z, high pressure was centered over MS, with ridge axes northeast and southwest. Aloft, water vapor imagery and stream flow analysis also indicated a deep layer ridge axis from the northwest Gulf through the TN valley. Low temperatures will fall closer to normal in the lower 40s for most areas. Tuesday will be similar to today with the ridge axes shifting east into the lower Appalachians and southeast U.
305 PM EST Mon Nov 8 2021 High pressure has settled over the region and will maintain dry weather through the middle part of the week.
Ludwig 1045 AM MST Mon Nov 9 2021 (09/18Z TAF period) VFR conditions are expected to prevail today as high pressure slides into the area.
326 PM EST Mon Nov 8 2021 The 12Z KKEY RAOB sampled falling heights at 300 and 200 mb, highlighting the anticyclonic wave break and the lengthening of the long wave trough axis noted on water vapor imagery. The low pressure system between North Carolina and Bermuda continues to pull further away from the Keys, which corroborates the rising heights between 925 and 500 mb sampled by this morning's RAOB. The lower tropospheric ridge will slide slowly east over the next several days.
1003 AM EST Mon Nov 8 2021 Warm, dry high pressure will dominate the weather across the region through the middle of the week.
(This afternoon through Tuesday night) Upper ridging is currently centered over much of the Gulf Coast. An upper trough begins to impact the West Coast Tuesday morning. High temperatures today and Tuesday will mostly be in the 70s and 80s across the area with temperatures slightly cooler on Tuesday due to a weak cold front/northerly wind shift.
1245 PM EST Mon Nov 8 2021 High pressure will gradually build into the region through the middle of the week.
1206 PM CST Mon Nov 8 2021 Weak cold front is making fast progress across the forecast area early this morning and will reach central Wisconsin by sunrise. With increased clouds and northwest winds, highs today will be several degrees cooler than what they were over the weekend, ranging from near 50 in central MN to the upper 50s for southern MN and western WI.
127 PM MST Mon Nov 8 2021 Quiet weather into early Tuesday as weak ridging in advance of a stronger wave moving into the Pacific northwest keeps dry weather over the area.
With southwesterly flow in the mid-levels and a cooler airmass moving east from the northern plains, this front will slowly drift towards an orientation north of and parallel to I-44. Surface and lower-layer moisture is modestly increasing today while a weak mid-level trough is expected to pass over Oklahoma early Tuesday. That, along with slightly cooler air will bring temperatures down closer to, but still above normal.
224 PM CST Mon Nov 8 2021 Warmer temps have moved into the area today thanks to upper level ridging, and highs are in the low 70s for most of the mid state.
Incoming snow storm has some pretty mild subtropical air, so snow levels will rise during the day tomorrow, but northwest wind after the low passes to the east will bring back snow showers for the end on Tue night. In the Snake River plain/eastern Magic Valley, measureable snow is only found in higher elevations than Rexburg in the I-15 corridor, and in the highlands around the INL and Craters of the Moon property, and it all appears to be less than 0.
