In addition, high temperatures will trend cooler in the west today, then areawide Tuesday, as a disturbance passes to the north of New Mexico. A fast-moving upper low will move east-northeast across the central Rockies thru tonight. The main story today will be widespread breezy to lcl windy conditions as stronger winds aloft approach within the base of the upper low. Ridge top winds will be howling with gusts up to 55 mph common on the higher peaks. Just enough moisture in the base of the upper wave may scrape the high terrain of far northern NM for a couple snow showers tonight. Widespread breezy west winds, cooler temps, and very low dewpoints are in store for NM on Tuesday.

Upper short wave trough along the central Gulf coast will move east and weaken tonight. This should bring a decrease in the high cloudiness late tonight. With light winds, low temperatures tonight will range from the upper 40s over interior se Ga to the lower 60s near the ne Fl coast.
/NEW/ /This afternoon through Monday/ High pressure at the surface will be transitioning east of the region through the the short term period as a strong disturbance migrates through the Central Rockies and into the Central/High Plains. Highs tomorrow will be around 5 degrees warmer than today (around 80 degrees).
An upper level trough will move across northern Utah today into Tuesday. High pressure will build into the region once again mid week. This is shown well in the new GFS and the high resolution models.
Tonight, a cold frontal boundary presently draped over north central through western Montana will transition through the CWA. This will lead to cooler temperatures for the region Tuesday with highs failing to reach 50 degrees in most locations.
Trended a little cooler than guidance in the east and near guidance in the west where winds aloft are expected to be a little bit stronger. It will be unseasonably mild with highs in the lower to middle 70s away from Lake Michigan. Leaned toward the warmer MAV guidance for highs based on the model cool bias in the day 2 forecast of high temperatures over the last few days.
Smooth flying is the story for the next 24 hours as high pressure remains settled in.
110 PM EDT Mon Oct 18 2021 High pressure will build across the region this week, resulting in dry conditions and warming temperatures.
Overall, upper ridging will maintain its hold over the region through the near term period. Meanwhile, at the surface, high pressure will continue to progress east over the region and settle over the Appalachians by Tuesday morning. Lows tonight will then be a touch warmer as we transition to easterly and eventually southeasterly flow (and moisture begins to increase). Therefore, temperatures in the upper 40s to lower 50s north of I-10 and the lower to upper 50s south are expected. Some spots over far interior southeast Mississippi and southwest Alabama could possibly see cooler lows, closer to the mid 40s. Highs Tuesday afternoon will likely be warmer as a gradual warming trend begins, with temperatures ranging in the mid 70s to around 80 degrees.
1126 AM EDT Mon Oct 18 2021 A surface analysis this morning reveals a continental high pressure cell centered over the Tennessee Valley. The system is supported aloft by a robust ridge extending northward from the Gulf of Mexico to Canada. The Florida Keys lie at the southern flank of the high pressure cell, which is migrating eastward. A weakening cold front was analyzed from the northern Bahamas across southern Florida to the southern Gulf of Mexico. A weakening cold front will become stationary near the Florida Keys this afternoon. Meanwhile, a robust high pressure ridge will build over the southeastern United States and Florida.
255 PM CDT Mon Oct 18 2021 An upper-level ridge will continue to progress slowly eastward across the Midwest through Tuesday, imposing persisting large-scale subsidence and dry conditions over the region. This subsidence will briefly be counteracted by a shallow, low-amplitude upper-level trough navigating the crest of the ridge Tuesday morning into afternoon; however, this feature will only be able to generate scattered/broken upper-level clouds during that time period. A low- level ridge will also be located to the east of the CWA, promoting south-southwesterly flow and weak WAA through Tuesday. Despite the WAA, Tuesday's high temps should be similar to today's, possibly a couple degrees cooler across southeastern MO and southwestern IL due to the upper-level cloud cover potentially lingering into afternoon and surface winds having less of a southwesterly component than today.
(This evening through Tuesday) A closed upper low, currently over the Intermountain West region, will track east into the Central rockies by tomorrow. Lee trough will keep low level southerly flow intact, with low level moisture increasing tonight. Temperatures will be warmer tonight with overnight lows in the 50s, with highs tomorrow in the low to mid 80s.
1207 PM EDT Mon Oct 18 2021 Cool, dry Canadian air will remain across the Carolinas for the next couple of days as high pressure slowly moves eastward.
Lows tomorrow night should respond with temperatures several degrees warmer than tonight.
Warm and dry conditions expected to continue through Tuesday, prior to a cold front arrival Tuesday night. Upper level trough currently east of the Reno NV area is expected to track towards the Salt Lake area this evening. In general warm and dry southwest flow out ahead of this trough is expected. With the warmer start to the day on Tuesday and continued south to southwest flow highs will likely be in the upper 70s to mid 80s. Winds will shift out of the north and a cold front is expected to move through after midnight Tuesday night. As a result morning lows will be much cooler with mid 30s in the northwest and mid to upper 40s in the southeast.
Further west over the western CONUS, a closed upper level low will move into the upper midwest and push the ridge eastward.
1235 PM CDT Mon Oct 18 2021 (Today and tonight) High level cloud cover will increase today downstream of upper low that has progressed onshore in northern California. This is expected to result in high temperatures a few degrees cooler than yesterday, but it will still be a fine day for the middle of October.
300 PM EDT Mon Oct 18 2021 Ridging will continue to keep central Indiana dry through the short term. as the dome of high pressure to our south drifts to the southern Appalachians, all the while blocking Gulf moisture while providing subsidence amid the lower levels. The associated mid- level ridge axis will slowly settle over the Mid-West by Tuesday night.
234 PM CDT Mon Oct 18 2021 Currently this afternoon, an upper ridge remains over the central CONUS, with the ridge axis over Missouri. Farther west, a potent upper trough is located over the Great Basin area. The approach of this trough has led to lee cyclogenesis across eastern Colorado. Between the lee cyclone to the west and high pressure to the east, a tight pressure gradient is contributing to strong southerly flow and gusty conditions across eastern Kansas. A south breeze will persist overnight, helping keep temperatures warmer than the past few nights. As low pressure lifts northeast into Nebraska tomorrow, south winds will once again gust to 25-35 mph. Temperatures should be a few degrees warmer than today, with highs around 80. Overnight Tuesday, the low pressure to the north will push a cold front towards the area.
635 PM CDT Mon Oct 18 2021 An upper-level ridge will continue to progress slowly eastward across the Midwest through Tuesday, imposing persisting large-scale subsidence and dry conditions over the region. This subsidence will briefly be counteracted by a shallow, low-amplitude upper-level trough navigating the crest of the ridge Tuesday morning into afternoon; however, this feature will only be able to generate scattered/broken upper-level clouds during that time period. A low- level ridge will also be located to the east of the CWA, promoting south-southwesterly flow and weak WAA through Tuesday. Despite the WAA, Tuesday's high temps should be similar to today's, possibly a couple degrees cooler across southeastern MO and southwestern IL due to the upper-level cloud cover potentially lingering into afternoon and surface winds having less of a southwesterly component than today.
The associated dry cold front will push through central and northern New Mexico Tuesday, resulting in slightly cooling and northwest breezes.
Will be watching cold front drop south- southeast from Canada overnight into Tuesday AM. Impacts in the short term will be minimal, though temps much cooler, with a dry cold frontal passage expected to bring much cooler weather to the area tomorrow. Cloudy and much cooler than today with highs 20 to 30 degrees cooler Tuesday, in the 40s and 50s.
305 PM MDT Mon Oct 18 2021 A low pressure circulation moving over the Great Basin will bring some light snow to portions of Lemhi County Idaho and over high terrain near the Continental Divide across southwest Montana this evening through Tuesday morning.
700 PM CDT Mon Oct 18 2021 This afternoon, we are seeing gusty south winds and a slight increase in upper level clouds as the upper ridge shifts to our east. This will force a cold front into the area by evening, but ahead of this we will see another warm and breezy day. Of additional concern is the westerly wind shift as the cold front moves into the area in the late afternoon/evening. Some light rain could also develop later overnight over northern parts of the area as the upper low ejects out over Nebraska.
652 PM EDT Mon Oct 18 2021 Cool, dry Canadian air will remain across the Carolinas for the next couple of days as high pressure slowly moves eastward.
Tonight's lows will be warmer than the previous, only dropping to the mid 50s overnight as low level moisture increases. It will be quiet Tuesday, outside of possible breezy winds again across the area as the surface pressure gradient tightens from a well-developed low pressure system traversing eastward into the Plains.
907 PM EDT Mon Oct 18 2021 A ridge of high pressure extending from the Upper Great Lakes to the Lower Ohio Valley will slide east over the next day or two.
Ridging will continue to keep central Indiana dry through the short term. as the dome of high pressure to our south drifts to the southern Appalachians, all the while blocking Gulf moisture while providing subsidence amid the lower levels. The associated mid- level ridge axis will slowly settle over the Mid-West by Tuesday night.
Overnight lows in the mid to upper 60s for most locations, as normally cooler inland/rural spots drop into the low 60s, except for the barrier islands of the Space/Treasure Coasts where it will be in the low 70s due to persistent east wind.
/15/ Tonight and Tuesday: Ridging surface and aloft will remain dominant through the period resulting in dry weather with cooler than normal temperatures again tonight followed by warmer temperatures topping out near normal Tuesday. Under mostly clear skies and a light wind, radiational cooling of our cool dry airmass will help temperatures bottom out in the low to mid 40s again.
The upper low causing these showers will intensify as it moves from western Utah tonight into southern Wyoming Tuesday, too far away to bring pcpn to our CWA. Our pcpn will come instead from the next Pacific trough that will come inland Tuesday night.
805 PM EDT Mon Oct 18 2021 A ridge of high pressure overhead will slide to the east over the next day or two.
838 PM EDT Mon Oct 18 2021 High pressure anchored near Tennessee is continuing to bridge into the Florida Keys and coastal waters. The stratocu deck which was around the Lower Keys earlier is beginning to push off to the southwest and will likely mix out overnight. The drier air, and near zero chance of rain, should persist through tomorrow evening, if not longer, as the aforementioned ridge begins to slide eastward towards the Atlantic. Overall, no changes are necessary to the afternoon forecast package, as conditions look to be a little cooler and less humid than the past week.
945 PM EDT Mon Oct 18 2021 High pressure center is currently along the GA/AL border and will continue to shift eastward overnight. The cirrus has interrupted the diurnal curve this evening (slowed it down) and temps are running a little warmer than forecast. /Issued 253 PM EDT Mon Oct 18 2021/ The short term will remain quiet with a high pressure ridge in place across the SE. Temperatures will largely stay around normal for this time of year with highs today in the low 70s. Temperatures will likely begin to climb back into the lower 80s in south and central Georgia beginning to tomorrow.
726 PM EDT Mon Oct 18 2021 High pressure and cooler weather triumphs through midweek.
If cloud cover persists long enough, NE FL lows may be slightly warmer than what is currently forecast. Clouds are expected to thin tomorrow, making way for a pleasant mostly sunny day with highs in the lower 80s. Upper short wave trough along the central Gulf coast will move east and weaken tonight. This should bring a decrease in the high cloudiness late tonight. With light winds, low temperatures tonight will range from the upper 40s over interior se Ga to the lower 60s near the ne Fl coast.
956 PM CDT Mon Oct 18 2021 The cold front continues to slowly sag into northwest North Dakota late this evening. This potential is the result of cold air advection intersecting a subtle theta-e ridge, and will essentially be cloud ceilings lowering to the surface if it materializes. The cold front is starting to move into far northwest North Dakota, where stronger northerly winds and surface pressure rises are being noted. Tonight, a cold frontal boundary presently draped over north central through western Montana will transition through the CWA. This will lead to cooler temperatures for the region Tuesday with highs failing to reach 50 degrees in most locations.
Similar to last night, the only real changes made to the gridded forecast was to tweak the marine winds upwards using some of the higher resolution guidance.
an upper level low pressure area currently spinning over western Utah is forecast to move into northwest Colorado tonight. South to southwest winds are expected at the surface with the highest speeds of 10 to 20 mph and gusty through about midnight. the upper low is expected to continue a northeast motion into western Nebraska by the end of the day then into northeast Nebraska overnight. A strong cold front will move through from west to east during the day with northwest winds gusting up to 40 mph expected, mainly along and north of the interstate. High temperatures are expected to range from the lower 60s to lower 70s in far eastern Colorado to the lower 70s to lower 80s elsewhere, warmest in the Norton and Hill City areas. Low temperatures drop into the lower 30s to lower 40s.
CMiller (Issued 249 PM CDT Mon Oct 18 2021) Tonight through Tuesday night: Tonight will be another clear and calm night thanks to high pressure overhead. Winds will pick up quickly on Tuesday out of the southwest as low pressure approaches from the Plains. High temperatures Tuesday will be similar or just a notch warmer than the highs today, in the lower 70s.
627 PM CDT Mon Oct 18 2021 High pressure continues over the area.
/Issued 253 PM EDT Mon Oct 18 2021/ The short term will remain quiet with a high pressure ridge in place across the SE. Temperatures will largely stay around normal for this time of year with highs today in the low 70s. Temperatures will likely begin to climb back into the lower 80s in south and central Georgia beginning to tomorrow.
Skies are clear across the Upper Midwest as the region sits on the northwest side of high pressure centered over the western half of Tennessee. Temperatures at 2 PM were in the lower to mid 70s with dewpoints in the mid to upper 40s. Tranquil weather continues across the region as high pressure sits to our southeast. An amplified 500 MB pattern continues through the short term with broad ridging across the Midwest. The ridge axis is along a line from eastern Michigan southwestward through Arkansas.
308 PM MDT Mon Oct 18 2021 Upper low currently over Nevada will track to the north and east over the next day and a half, eventually crossing southern Wyoming. An associated cold front will drop south through the region this evening and overnight. Latest ensembles have continued with the trend of the low tracking farther south. Temperatures on Tuesday will be much cooler, with highs in the 40s most places, and lows in the 20s to lower 30s Tuesday night.
757 PM EDT Mon Oct 18 2021 High pressure will prevail across the region most of this week.
634 PM CDT Mon Oct 18 2021 (This evening through Tuesday) Temperatures will warm a little tomorrow compared to today as we continue with the southerly flow bringing warmer air into the area.
Lows tonight will range from the low to upper 50s. /JNE/ Prior discussion below: Tonight and Tuesday: Ridging surface and aloft will remain dominant through the period resulting in dry weather with cooler than normal temperatures again tonight followed by warmer temperatures topping out near normal Tuesday. Under mostly clear skies and a light wind, radiational cooling of our cool dry airmass will help temperatures bottom out in the low to mid 40s again.
710 PM EDT Mon Oct 18 2021 High pressure will build across the region this week, resulting in dry conditions and warming temperatures.
650 PM CDT Mon Oct 18 2021 The cold front is starting to move into far northwest North Dakota, where stronger northerly winds and surface pressure rises are being noted. Tonight, a cold frontal boundary presently draped over north central through western Montana will transition through the CWA. This will lead to cooler temperatures for the region Tuesday with highs failing to reach 50 degrees in most locations.
Currently this afternoon, an upper ridge remains over the central CONUS, with the ridge axis over Missouri. Farther west, a potent upper trough is located over the Great Basin area. The approach of this trough has led to lee cyclogenesis across eastern Colorado. Between the lee cyclone to the west and high pressure to the east, a tight pressure gradient is contributing to strong southerly flow and gusty conditions across eastern Kansas. A south breeze will persist overnight, helping keep temperatures warmer than the past few nights. As low pressure lifts northeast into Nebraska tomorrow, south winds will once again gust to 25-35 mph. Temperatures should be a few degrees warmer than today, with highs around 80. Overnight Tuesday, the low pressure to the north will push a cold front towards the area.
632 PM CDT Mon Oct 18 2021 (This evening through Tuesday) A closed upper low, currently over the Intermountain West region, will track east into the Central rockies by tomorrow. Lee trough will keep low level southerly flow intact, with low level moisture increasing tonight. Temperatures will be warmer tonight with overnight lows in the 50s, with highs tomorrow in the low to mid 80s. The higher gusts and speeds are expected to be at KABI and KSJT.
1025 PM EDT Mon Oct 18 2021 High pressure will prevail across the region most of this week.
Low pressure is moving into the Rockies tonight and a brief ridge is over the area. The ridge won't remain long as satellite imagery shows the next trough moving towards the coast.
1144 PM CDT Mon Oct 18 2021 High pressure with some high clouds will continue over the area. Tonight Through Wednesday At mid-afternoon, weak ridging/quasi-zonal flow was noted at the mid and upper levels over Arkansas with strong surface ridging in place to the east of the region. This pattern was bringing fair skies and light winds to the area with surface dew points generally in the lower to mid 40s. This pattern will remain mostly unchanged tonight through Tuesday before a strong trough of low pressure pushes into the northern/central Plains Tuesday night/Wednesday. The approaching trough will cause the mid/upper flow to become southwesterly while surface pressures decrease and weak southerly low level flow develops. Highs on Wednesday will range from the lower 70s over the northern higher terrain to the lower 80s over the far south.
246 AM EDT Tue Oct 19 2021 Cool, dry Canadian air will remain across the Carolinas for the next couple of days as high pressure slowly moves eastward. As the high moves offshore Wednesday, winds will shift southwesterly and temperatures will rebound above normal.
244 AM CDT Tue Oct 19 2021 Water vapor satellite shows a vigorous upper level low spinning over the Great Basin and swiftly moving eastward over the Rockies. The upper jet associated with this upper low will pivot over the Rockies and assist in lee cyclogenesis over southwestern Nebraska this morning. As the surface cyclone slides northeastward, a cold front will begin to surge southeastward into Kansas this afternoon. Ahead of this cold front, the pressure gradient will remain quite tight keeping stout southerly winds across the region.
337 AM CDT Tue Oct 19 2021 An upper level ridge will remain over the area again today. An upper low will move across the northern Plains on Wednesday. The drier air mass will still be in place but with the cap weakening and lift from the front, there will likely be enough moisture in the lower levels of the atmosphere for some scattered showers to develop along the front during the afternoon hours, generally east of Highway 65. Highs are Wednesday will again warm into the lower to upper 70s with the warmest conditions across south central MO where the front will move through later in the day.

1057 PM CDT Mon Oct 18 2021 (This evening through Tuesday) Temperatures will warm a little tomorrow compared to today as we continue with the southerly flow bringing warmer air into the area.
106 AM CDT Tue Oct 19 2021 High pressure has shifted east into the southeast U. Highs should easily reach the lower to middle 70s in valley locations, and upper 60s atop the highest plateau areas.
1156 PM EDT Mon Oct 18 2021 High pressure will prevail across the region most of this week.
(This afternoon through Tuesday night) WV imagery shows the upper trough digging through NV, and forecast to eject to the South Dakota/Nebraska border by 12Z Wednesday. Otherwise, leeside troughing has developed excellent return flow over the area this afternoon, and a LLJ is set to develop overnight and bring 50F dewpoints or better as far west as KINK by 12Z Tuesday, keeping overnight lows 5-10F above normal. Tuesday, as the upper trough ejects north of the region, thicknesses are forecast to increase, ramping up afternoon highs to 5-10F above normal for a reprieve of cooler temperatures.
Low temperatures should reach the lower 40s tonight with some isolated cold spots in the upper 30s possible. High temperatures should be similar to today or slightly warmer with highs in the upper 60s/lower 70s. WAA on the backside of the southeast US High will warm daytime highs into the low/mid 70s.
A cold front will sweep through tuesday night bringing a few showers and temperatures closer to average for the end of the week. Today: Mainly quiet weather will continue this afternoon as upper level ridging builds into the area. At the surface, high pressure will continue to push east and a tightening pressure gradient will shift in. Tuesday and Wednesday: Tuesday morning will see lows in the low to mid 50s.
