(Today through Tuesday) Key Messages: - Slightly warmer temps continue to build in today and tomorrow.
957 AM EDT Mon Oct 21 2024 High pressure dominates the local weather pattern through the week, allowing for dry conditions to continue. Temperatures remain mild early this week before the next cold front pushes through by mid week, bringing near normal temperatures. Current sfc analysis depicts high pressure overhead with clear skies, calm winds, and temps in the 50s to around 60 F as of 10 AM. With the high still overhead, lows cool once again to the low-mid 40s inland and upper 40s to around 50F along the coast. At the surface, high pressure remains over the area early this week with dry weather continuing. Meanwhile, a ridge aloft continues to build across the eastern CONUS.
623 AM CDT Mon Oct 21 2024 Another dry week is expected as high pressure continues.
604 AM CDT Mon Oct 21 2024 (Today through Tuesday Night) High pressure is expected to control the weather pattern through much of the period.
Breezy northeasterly winds are expected again today as the high pressure builds to our north.
1017 AM EDT Mon Oct 21 2024 Another day dominated by the strong ridge of high pressure, and the forecast looks to be on track. Discussion: Currently early this morning, ridging is approaching from the west ahead of a closed upper low.
1003 AM EDT Mon Oct 21 2024 High pressure sinking south will keep broad southwest flow over the region through midweek.
Weak troughing passes through the Pacific NW today, bringing onshore flow to Northern CA.
314 AM MDT Mon Oct 21 2024 A cold front brings lower elevation rain with mountain snow along the northern Continental Divide today. Cooler temperatures settle in Tuesday through the rest of the work week.
High pressure aloft slowly building northward over New Mexico over the next several days. Satellite showing upper low now over central Colorado with the main trough extending down across SE New Mexico and west Texas. There may be another weak short wave northwest of the main trough but of little or no impact. Dry air becoming well established behind the main trough. This high mostly remains in place over northern Mexico and far southern New Mexico into this weekend.
616 AM CDT Mon Oct 21 2024 - Well above normal temperatures today, with highs in the upper 70s to the lower 80s (15 to 25 degrees above normal).
309 PM EDT Mon Oct 21 2024 Dry weather is expected to prevail through the week, as high pressure remains in control.
1248 PM EDT Mon Oct 21 2024 High pressure sinking south will keep broad southwest flow over the region through midweek.
115 PM EDT Mon Oct 21 2024 High pressure remains in charge, with sunny days and warmer afternoons into midweek.
109 PM EDT Mon Oct 21 2024 High pressure remains in charge, with sunny days and warmer afternoons into midweek.
1239 PM CDT Mon Oct 21 2024 Air temperatures have been rapidly climbing from the low to upper 70s over the past hour across the ArkLaTex, indicating highs in the mid to upper 80s as advertised.
1230 PM CDT Mon Oct 21 2024 (Today and tonight) As of 2 AM CDT, the upper low can be seen spinning over southwest Colorado on mid-level satellite water vapor imagery. Isolated thunder remains possible with the weak shower activity, but any storm that develops will be elevated and remain sub-severe with the better ascent and instability north of the forecast area and closer to the upper low. The window for instability will remain short with the setting sun and cooler surface temperatures, along with a loss of the better forcing aloft as the upper low ejects northeastward.
1235 PM CDT Mon Oct 21 2024 The short term forecast remains on track: High pressure with generally easterly winds dominates the region giving way to clear skies. Temperatures look to trend a degree or two warmer today throughout the CWA, with dew points following suit. /OAJ/ Dry and warmer conditions will remain the forecast theme over the upcoming week. With low and midlevel ridging persisting across our region, we'll see high temperatures continue to trend upward today and continuing through the work week. By the weekend, a mid/upper trough will push a cold front southward toward the area, but the front will stall as it approaches or moves into the area.
(This evening through Tuesday) Crystal clear skies remain over much of the eastern CONUS with a 1030mb ridge of high pressure centered over the Ohio River Valley. A 500mb ridge remains off to our southwest over far southern Texas and Mexico. With a dry easterly flow at the surface this afternoon, dewpoints will remain mostly in the 40s as high temperatures rise into the lower 80s areawide. We'll have one more chilly night tonight in some spots, dipping down into the 40s with a few warmer spots around 50 degrees. Dewpoints will increase into the 50s to near 60 across far southeastern counties, with highs continuing to warm into the low to mid 80s.

Conditions are comfortably warm this afternoon, with temperatures generally in the lower to mid 80s and dew points in the lower 70s. Expansive high pressure over the Eastern Seaboard continues to slowly weaken, with the resulting loosened pressure gradient corresponding to slackening northeasterlies. This high will continue to collapse throughout much of the work week, with a secondary strong area of high pressure expected to build in its wake. From synopsis, a broad high pressure system over the eastern United States will promote moderate to fresh northeast breezes through the end of the work week. As a strong, second area of high pressure builds across the Eastern Seaboard over the weekend, winds will increase once again, becoming fresh to strong.
833 AM PDT Mon Oct 21 2024 Weak cold front this morning and much better humidities today. (Today and tonight) The weak cold front moving through the region is evident on satellite with ample high clouds present. At the surface, high temps today a few degrees cooler than yesterday.
135 PM EDT Mon Oct 21 2024 High pressure and dry air over the eastern US will keep the forecast dry through the week. A series of cold fronts may push into the Southeast late this week and over the weekend bringing temps a little closer to normal, but rainfall is unlikely. Tonight: High pressure will continue to persist over the region with strong radiational cooling conditions expected. High pressure and upper ridging over the area are expected to remain over the area, keeping the area dry through the short term. Meanwhile, an upper trough over the central CONUS is forecast to move toward the region, but lift northward as it approaches, leaving relatively high heights over the forecast area. Upper trough continues trekking eastward and send a weak, moisture starved front through the Southeast.
Quiet weather continues as a weak upper level ridge moves over the southwestern U. which will bring back warmer than normal temperatures. By mid-week a small upper level trough moves over northern Nevada which may bring chances for precipitation then quickly move out as the ridge builds back up. Over the weekend, a stronger upper level trough is expected to move over northwestern U. to bring in cooler temperatures as well as some showers and snow. Tonight through Tuesday Some slight upper level ridging is expected to develop tonight and into Tuesday, keeping weather conditions quiet as well as light winds.
Light mountain snow is also expected over the higher terrain along the Rocky Mountain Front.
High pressure will build into northern Arizona over the coming week, bringing warmer temperatures and dry conditions. High pressure will be the primary influence on the weather in Arizona over the coming week.
The highest potential spread rates are located from Tulsa and points north and west from there. The upper low that been sitting over the Southwest the past few days is lifting northeast into the central Plains today. The forecast area will see some elevated shower and isolated storm chances sweep across the area tonight as the base of the parent upper trough sweeps across.
131 PM EDT Mon Oct 21 2024 High pressure dominates the local weather pattern through the week, allowing for dry conditions to continue. Temperatures remain mild early this week before the next cold front pushes through by mid week, bringing near normal temperatures. Current sfc analysis depicts high pressure overhead with clear skies, calm winds, and temps in the 50s to around 60 F as of 10 AM. With the high still overhead, lows cool once again to the low-mid 40s inland and upper 40s to around 50F along the coast. At the surface, high pressure remains over the area early this week with dry weather continuing. Meanwhile, a ridge aloft continues to build across the eastern CONUS.
1111 AM CDT Mon Oct 21 2024 (Today through Tuesday Night) Ridging over the East/Central CONUS will continue to bring warm and benign weather through the first half of the work week. While the mid/upper level ridge will be flattened by a disturbance passing through the Mid Mississippi River Valley, little change in thicknesses and southeasterly winds suggest continued warming through Tuesday. Highs should be in the 80s inland and upper 70s along the coast today, reaching the lower 90s on Tuesday. Lows for tonight/Tuesday morning will be in the lower 50s/lower 60s inland and mid 60s/lower 70s along the coast.
1133 AM MDT Mon Oct 21 2024 High pressure aloft slowly building northward over New Mexico over the next several days. Satellite showing upper low now over central Colorado with the main trough extending down across SE New Mexico and west Texas. There may be another weak short wave northwest of the main trough but of little or no impact. Dry air becoming well established behind the main trough. This high mostly remains in place over northern Mexico and far southern New Mexico into this weekend.
325 PM EDT Mon Oct 21 2024 High pressure today will exit off the coast on Tuesday.
1009 AM CDT Mon Oct 21 2024 - Well above normal temperatures today, with highs in the upper 70s to the lower 80s (15 to 25 degrees above normal).
(Tonight through Tuesday night) High pressure in control through the region will keep us in a quiet pattern through the short term period. the high tide this evening/tonight looks very similar, and the 1ft above predicted has held steady all day, so expect similar values for tonight.
(Rest of today through Tuesday) Models depict broad and deep high pressure dominating the eastern half of the CONUS, with SoFlo firmly enveloped in its southeastern periphery. Meanwhile, a mid level trough remains over the western Atlantic, which should remain in place during the short term. Tonight's lows will range from the low 70s over the interior and Gulf Coast, to the mid 70s over the East Coast.
Scattered high level clouds continue to move in from the south this afternoon and evening ahead of a upper level low moving through Nebraska into SD and MN. Another upper level wave moves in from southern Canada later tonight and into Tuesday which will bring increased precipitation chances, breezy conditions, and cooler temperatures. This secondary system is riding along a upper level ridge situated over the western United States. The front associated with the low pressure system works its way through the area sunrise on Tuesday bringing rain and instability to the area.
Discussion: The strong high pressure over our area will gradually edge east during the period, but will continue to be the main influence on our weather.
Current Water Vapor and upper air models show upper low over the central plains, with upper trough off the NW PAC coast. Surface map shows weak trough running through the western SD plains into NE, with a low pressure over western MT this afternoon.
1100 AM CDT Mon Oct 21 2024 Air temperatures have been rapidly climbing from the low to upper 70s over the past hour across the ArkLaTex, indicating highs in the mid to upper 80s as advertised.
119 PM MST Mon Oct 21 2024 High pressure ridging will lead to above normal temperatures for much of the next 7 days, with high temperatures returning to the nineties, up to 5-10 degrees above normal, during the second half of this week and this weekend. Longwave ridging will lead to above normal temperatures, with lower desert highs in the 90s beginning Tuesday.
1239 PM EDT Mon Oct 21 2024 High pressure today will exit off the coast on Tuesday.
A few high clouds will move over us this evening into the overnight as a trough kicks out of the Rockies into the Great Lakes. We will start to get some weak southerly flow late in the day as the high slowly pushes east.
1034 AM MDT Mon Oct 21 2024 Morning Update: Increased winds slightly with expected cold front moving through tonight.
200 PM MDT Mon Oct 21 2024 - Warm and dry today; cold frontal passage tonight.
Light northerly winds overnight shift to a light southeasterly for the afternoon/evening/ /16 (Now through Tuesday night) A combination of upper low pressure off the East Coast and upper level high pressure over old Mexico and the western Gulf of Mexico will create dry northwesterly upper flow over the Southeast into mid week.
1203 PM MDT Mon Oct 21 2024 - A few showers over the Pikes Peak Region this morning, then drier and breezy behind departing upper low this afternoon. As upper low moves into the central plains today, moisture and lift wrapping around the system will combine with rather steep lapse rates to generate a round of showers over the Central Mountains and the Pikes Peak Region, with most activity occurring this morning.
(Tonight through Tuesday night) An upper level ridge extends from Deep South Texas to the mid- Mississippi Valley and is forcing a low into the middle of the country this afternoon. The low level flow from the southeast will strengthen tonight and the airmass will become moister across the area. This will lead to increased overnight/morning cloudiness, but with the ridge aloft still no rain. With warm, moist advection and more clouds overnight lows will be warmer. Most places east of about Uvalde will be 5-10 degrees warmer Tuesday morning than they were today. Highs Tuesday will be a degree or two warmer however as clouds give way to mainly sunny skies.
The upper level low will move northeast of the area this evening leaving western Kansas under westerly flow aloft over the next few days. A few upper level impulses will move through the Northern Plains this week and help push a weak cold front through the area. These will be dry fronts with a wind shift to the north and slightly cooler temperatures.
1205 PM CDT Mon Oct 21 2024 Another dry week is expected as high pressure continues.
/SEC (Today through Tuesday) Key Messages: - Slightly warmer temps continue to build in today and tomorrow.
Issued by National Weather Service Hastings NE 1246 PM CDT Mon Oct 21 2024 - Scattered showers and thunderstorms are expected today as a storm system and associated cold front crosses the area.
146 PM EDT Mon Oct 21 2024 High pressure will continue to prevail over the Ohio Valley, resulting in sunny skies, light wind, and mild temperatures.
233 PM EDT Mon Oct 21 2024 High pressure dominates the local weather pattern through the week, allowing for dry conditions to continue. Temperatures remain mild early this week before the next cold front pushes through by mid week, bringing near normal temperatures.
108 PM EDT Mon Oct 21 2024 Another day dominated by the strong ridge of high pressure, and the forecast looks to be on track. Discussion: Currently early this morning, ridging is approaching from the west ahead of a closed upper low.
- Cooler air arrives mid week and for the weekend. A mid level closed low is lifting across the central plains this afternoon and will move northeast over Michigan late Tuesday as it weakens considerably. Models are indicating a cooler bubble of air, roughly 5 degrees lower at 850mb compared to today, arriving within the southwest flow tomorrow afternoon. Increasing mid-level moisture will also be moving in ahead of this low will also provide a boost in clouds by the afternoon. These two factors should help keep high temperatures a few degrees cooler compared to today and likely below the record highs for tomorrow. The weakening wave will be quickly followed by a deeper trough and an associated cold front being directed by a 120 knot upper jet.
1237 PM EDT Mon Oct 21 2024 High pressure persists over the region through midweek.
Daytime highs will climb into the lower to middle 80s, which is seasonably warm for the later stages of October.
A cold front brings lower elevation rain with mountain snow along the northern Continental Divide today. Cooler temperatures settle in Tuesday through the rest of the work week.
258 PM EDT Mon Oct 21 2024 High pressure will continue to prevail over the Ohio Valley, resulting in sunny skies, light wind, and mild temperatures.
(This evening through Tuesday night) Dry high pressure will remain planted across the area, suppressing rain chances and keeping relative humidity seasonably pleasant. Low dewpoints and clear skies will allow overnight lows to fall into the low to mid 50s north and into the mid 50s to lower 60s south, while afternoon highs will rebound into the low to mid 80s.
A trough to the northwest will continue to bring light rain showers across southeast Oregon and the West Central Mountains of Idaho. Rainfall amounts are expected to remain light, with only a few hundredths of an inch in the lower valleys and up to a quarter-inch on the mountain peaks. Breezy conditions are expected this afternoon, especially in southeast Oregon, as the pressure gradient tightens due to the inland movement of the trough.
A weak trough passing by to the north today brought some isolated light showers mainly to the Coast Range earlier this morning, as well as increased onshore flow and clouds. Gusty southwest winds are expected this afternoon over the Sierra Crest as a result of this troughing, and gusts of 20-30 mph will be possible into the early evening.
Issued by National Weather Service Grand Forks ND 1021 AM CDT Mon Oct 21 2024 - A cold front will bring a 20 to 60 percent chance of light rain across the northern half of the state mainly late tonight through Tuesday morning, along with breezy to windy conditions late tonight through the day Tuesday. The highest rain chances are closer to the Canadian border. This will bring the return of sub- freezing temperatures with most locations forecast to drop into the 20s.
(Now through Tuesday night) A combination of an upper low off the East Coast and upper level high pressure over old Mexico and the western Gulf of Mexico will create dry northwesterly upper flow over the Southeast into mid week.
1223 PM CDT Mon Oct 21 2024 (Today through Tuesday) An upper level ridge will build over our area today into Tuesday as an upper level low over the Central Rockies opens into a trough and moves over the Central Plains today to the western Great Lakes on Tuesday. The surface ridging that has kept the deeper lower level moisture over our western areas will drift off to the east allowing a moist southerly flow to return to all areas tonight into Tuesday. Although the moisture depth becomes shallower with no rain forecast as subsidence takes hold under the ridges, cannot rule out a few sprinkles in the early morning hours due to the low level jet.
344 PM EDT Mon Oct 21 2024 High pressure today will exit off the coast on Tuesday.
335 PM CDT Mon Oct 21 2024 - One more day of highs near 70 to our southeast before a cold front moves through. - Cooler temperatures but still above normal present for the rest of the week.
Strong heating will erode a midlevel cap in this area, but any activity is expected to be very isolated and short-lived given the lack of large-scale forcing with the exiting upper trough well to our north. Much cooler temperatures are expected tonight compared to last night, especially on the Caprock where the drier airmass, light winds, and clear skies will allow most locations to fall into the 40s by sunrise. On Tuesday, flow aloft will weaken and become more zonal as flat upper ridging builds to our south. Rising surface-500mb thicknesses will allow most locations to see highs in the 80s, with some locations off the Caprock reaching into the low 90s.
(This afternoon through Tuesday night) The upper low that brought us cooler conditions and cloudy skies continues to track north and east of our area, setting the stage for an upper ridge to gradually build. Tuesday is expected to be fairly warm thanks to increasing geopotential heights within the upper ridge.
This low should weaken as it heads towards the Atlantic seaboard and become more involved in the main westerly flow. At the surface, high pressure now situated over the Mid Atlantic was producing a light SE flow across the Tennessee Valley.
1231 PM CDT Mon Oct 21 2024 - Well above normal temperatures today, with highs in the upper 70s to the lower 80s (15 to 25 degrees above normal).
A nicely wrapped up upper level low pressure will move into NE through the afternoon into tonight. Right now tough to buy into the higher gusts with so little instability and while there is a dry layer in the lower levels it is not excessive. Otherwise southerly flow remains in place and overnight lows will be very mild in the lower to mid 50s.
Sunshine and warm temperatures are in place again today, as our area remains under the influence of an upper ridge of high pressure just to our east. Looking into the Plains, a increasingly moisture starved closed mid level low pressure is making its way slowly east through Kansas and Nebraska. Tuesday night, the upper pattern will see a strong trof build into the Midwest, with a surface cold front reaching our CWA in the evening hours northwest to west central Illinois by early morning.
257 PM EDT Mon Oct 21 2024 - A few showers possible later Tuesday into Tuesday night - Cooler with showers late week - A few showers possible later Tuesday into Tuesday night A southwesterly low level jet moves into the area Tuesday into Tuesday night. - Cooler with showers late week A couple of cold front will move through the region this week.
Today has seen the upper level ridge axis shift east into the Deep South, while an area of troughing pushes across the Central Plains. This trough's associated surface boundary will lose its organization as it drifts south and east, becoming all but indistinguishable on surface analysis by the time it arrives on the ArkLaTex's doorstep.
Tuesday will be a bit cooler in the wake of the low and "cold front".
Issued by National Weather Service Grand Forks ND 116 PM CDT Mon Oct 21 2024 - A cold front will bring a 20 to 60 percent chance of light rain across the northern half of the state mainly late tonight through Tuesday morning, along with breezy to windy conditions late tonight through the day Tuesday. The highest rain chances are closer to the Canadian border. Looking more into Tuesday's post-frontal air mass, continued cold air advection in the low levels amid unidirectional shear should help organize weak convection while squeezing out moisture to bring chance for scattered showers throughout the day Tuesday, aided by daytime heating in an October sun angle. This will bring the return of sub- freezing temperatures with most locations forecast to drop into the 20s.
The coasts and valleys will be a bit cooler today as offshore flow weakens, however, the interior areas will be warmer.
