1232 AM CDT Fri Sep 23 2022 (This afternoon through Friday night) Warm and dry weather will persist through the short term, as upper level ridging continues to dominate the weather pattern across Southeast New Mexico and West Texas. Given little, if any, change to antecedent conditions, tonight will be similar to last night with breezy south winds yielding lows a degree or two above normal for the first night of fall, generally in the lower to middle 60s for all but the mountain areas, where lows in the 50s are possible.
356 AM CDT Fri Sep 23 2022 (Issued 356 AM CDT Fri Sep 23 2022) Today through Saturday: High pressure will continue to shift east with light southerly winds today. The upper level low over Montana will slowly shift east with an area of upper level divergence setting up over us late this afternoon into tonight.
(Today and tonight) Upper troughing over the northern Rockies will continue to shift southeastward today, helping flatten the persistent upper ridge anchored over Texas. A warmer day is therefore expected as drier air is pulled northward across the region. Even as the upper ridge begins flattening, continued elevated thickness values with dry SSW surface flow will boost temperatures 5-10 degrees above seasonal averages this afternoon. A narrow plume of midlevel moisture stretched along the top of the ridge in tandem with the passage of a mild upper vort max may generate a few light sprinkles across the southern Panhandle near dawn Saturday.
Today: Warm air advection will increase in the surface - 700mb layer as a deep upper trough traverses the Northern Plains and Upper Midwest. Due to the widespread clouds, spotty light rain, and steady S/SSE breeze, it will feel on the cooler side today with highs only in the upper 50s to low 60s.
1227 AM CDT Fri Sep 23 2022 (Tonight through Friday) A surface front continues to push southward tonight, and is currently near TOI, where winds are calm and dewpoints still in the lower 70s. Deep-layer ridging will become centered further southeast over the Texas Gulf Coast through the day Friday. Highs will range from the upper 70s far north and in the higher elevations east to readings in the mid 80s far south and across the southwest.
Pesky lake clouds continue with an an overall increase in clouds ahead of approaching trough. (Issued 356 AM CDT Fri Sep 23 2022) Today through Saturday: High pressure will continue to shift east with light southerly winds today. The upper level low over Montana will slowly shift east with an area of upper level divergence setting up over us late this afternoon into tonight.
Max temps should be in the 80s most of the plains, with mid to upper 80s over the lower Ark River valley, and around 80 on the Divides.
Zonal flow will begin to transition to an upper level ridge that will bring a warming and drying trend to southern Oregon and northern California this week. Key Points: * Frost will be possible this morning and tonight for traditionally colder areas east of the Cascades as well as for the higher terrain. Meanwhile, east of the Cascades, expect some frost for many of our traditionally colder areas as well as some of the higher terrain. Temperatures will be near to slightly above normal today, continuing to increase as the ridge of high pressure continues to build in through the weekend.
Much drier is just off the surface and will scour out the low clouds and fog with a little mixing. An upper level trough passing north of Colorado will bring breezy west to northwest winds to parts of the area today. Lows across northeast Colorado should fall into the lower to mid 40s. A few cooler spots may see upper 30s. Saturday, Colorado will be on the eastern periphery of strengthening upper level ridge with NW/N flow aloft. Temperatures will be a little above normal over the lower elevations with highs in the low 80s.
953 AM EDT Fri Sep 23 2022 A cold front has passed through the CWA this morning, ushering in drier air. For today, we will see a break in the near to record temperatures from yesterday with highs in the lower to upper 80s across southeast Alabama and southwest Georgia and the upper 80s to lower 90s across the Florida Big Bend and Panhandle.
(Today through Saturday Night) Issued at 407 AM CDT Fri Sep 23 2022 An upper ridge continues to be centered over Texas this morning and northwest flow is over the Great Lakes. Also, an upper low is located in the northern Plains. The upper low will track along the Canadian border today and tonight and through the Great Lakes Saturday. The upper ridge will shift westward Saturday and Saturday night toward the Four Corners region. Drier air is over the region with dew points mainly in the lower to mid 50s. High pressure will be over the area today but a cold front will move from the Plains toward Arkansas tonight. Lows tonight will be in the lower 60s to around 70 degrees and in the lower 60s to lower 70s Saturday night.
High pressure continues to build across the region into the weekend with dry conditions and a gradual warming trend. In addition, Fort Ord and Bodega Bay profilers indicate an surge of drier air at the low levels (below 5000 feet). This is expected as we have high pressure building into the Great Basin, bringing warmer temperatures and drier conditions.
Today through Saturday night Dry and pleasant today with light winds and sunny skies as ridging begins to build over the southwest US. Warmer temperatures are expected today with highs generally in the 70s. Even warmer Saturday with above normal temperatures in the upper 70s and lower 80s as ridging intensifies. Slightly warmer nighttime lows generally in the 40s.
535 AM EDT Fri Sep 23 2022 High pressure should maintain dry weather through Saturday.
1026 AM EDT Fri Sep 23 2022 High pressure will extend across the area today and move off to the east on Saturday.
645 AM CDT Fri Sep 23 2022 Upper level low pressure will track eastward across the Northern Plains today. A cold front will move southeast across the area this morning on the backside of the system. Temperatures will actually be warmer today behind the front. High temperatures will be a few degrees warmer with another day of deep mixing. By mid to late week, the flow will decrease as upper level ridging builds eastward from the Rockies ahead of a long wave trough progressing eastward into the Pacific northwest and western Canada.
In wake of this boundary, expect mostly sunny conditions to continue, with northeast winds bringing in cooler and less humid conditions across most of the region, especially in comparison to the past few days. The exception will be across our most southwestern zones in East Texas, where highs will top out in the mid to possibly upper 90s, as the intrusion of cooler and drier air will be more limited due to the front becoming stationary just west of our CWA. Upper ridging will remain over the region today, but begins to flatten out as we move into the evening hours. Dry conditions will also continue, but the center of the upper ridge will start to push into the Southwest region of the CONUS during the day.
650 AM EDT Fri Sep 23 2022 Roller coaster of temperatures in store, reaching the peak Saturday before trending cooler.
621 AM CDT Fri Sep 23 2022 (Today and tonight) Upper troughing over the northern Rockies will continue to shift southeastward today, helping flatten the persistent upper ridge anchored over Texas. A warmer day is therefore expected as drier air is pulled northward across the region. Even as the upper ridge begins flattening, continued elevated thickness values with dry SSW surface flow will boost temperatures 5-10 degrees above seasonal averages this afternoon. A narrow plume of midlevel moisture stretched along the top of the ridge in tandem with the passage of a mild upper vort max may generate a few light sprinkles across the southern Panhandle near dawn Saturday.
Canadian high pressure will shift east of the region today, with developing return flow and WAA resulting in increasing clouds and perhaps a few sprinkles in central WI late in the afternoon.
Redevelopment this afternoon into the evening appears confined to the Devils Lake basin with the stronger forcing of the upper low and across the tri-state area into west central MN. The areas most likely to see higher amounts will be the Devils Lake basin with redevelopment of activity this afternoon as the center of the weakening upper wave approaches and also across the southern valley and west central MN as 500mb PVA pushes east on the base of the broad trough. Highs will hold in the 50s in MN today with some low 60s expected in eastern ND however with gusts to 30mph on south winds it will feel rather raw and cooler given the shower activity and dampness.
554 AM CDT Fri Sep 23 2022 (Today through Saturday) With the front now to our south, a pleasantly cool and dry airmass is filtering south through Central AL with dewpoints in the lower 50s across our north. This orientation will result in beautiful conditions today beginning with morning temps in the 50s north to mid 60s south warming up into the lower/mid 80s by the afternoon with mostly clear skies, but the best part will be the low humidity. Efficient radiational cooling tonight will lead to area- wide lows in the 50s and perhaps and few readings in the upper 40s in the cooler valley locations. Slightly warmer on Saturday once boundary layer winds become southeasterly, but without any moisture return another sunny, dry day is forecast.
717 AM EDT Fri Sep 23 2022 High pressure should maintain dry weather through Saturday.
600 AM CDT Fri Sep 23 2022 (Today through Saturday) Subtropical Ridge remains overhead today with weak ridging at the surface. A strong thermal ridge also lingers. An inverted trough moving onshore the lower Texas coast tonight will move farther west over central/southern Texas and northeastern Mexico on Saturday splitting the Subtropical Ridge. The moisture and weakening of the thermal ridge leads to "cooler" high temperatures well shy of any records on Saturday, though still above normal.
Water vapor imagery this morning shows Fiona continuing to lift north across the North Atlantic and is beginning to phase with a sharp trough digging across the New England States. Meanwhile, back to the west an upper level is churning across the Northern Rockies and sliding east into the High Plains. Thereafter, ridging across the western Atlantic will build back to the west briefly.
Surface temps currently in the upper 30s to mid 40s are the lowest seen across Southeast Michigan since May. Strong height rises ensue today allowing high pressure to build directly over the region. The departing thermal trough and abundant sunshine will bring highs to the mid 60s today with lighter winds. Midlevel ridge axis passes overhead this evening with the next trough quick to move in overnight into Saturday. Chances for light showers increase through the day on Saturday as the trough moves in, but will cap PoPs at slight chance to chance wording as low-level moisture will be limited and most of the activity will be directed across northern Michigan where the better jet forcing will reside.
on back side of upper low that is now in western ND. This spotty light precip will diminish before midday as the low continues to track eastward. JKL An upper low over eastern Montana is dominating our weather this morning with scattered showers, isolated thunderstorms and gusty winds over southern MT and north central WY. Look for the showers to dissipate from west to east this morning as the upper low moves eastward, such that much of south central MT should have dry weather by 6 AM MDT and southeast MT closer to noon MDT.
632 AM CDT Fri Sep 23 2022 (Now through Saturday) Mid-level ridging centered over Texas will continue to provide subsidence across Deep South Texas through much of the period. However, a 500mb inverted trough over the Southwest Gulf of Mexico will under cut the ridge as this feature moves westward towards the Northeast Mexican Coast. At the surface, high pressure across the Gulf of Mexico will maintain light to moderate east to southeast winds. Highs today and Saturday will range from the 80s at the beaches, the lower 90s near the coast and the mid to upper 90s farther inland.
High pressure centered aloft over Texas will continue to build eastward over the region for the next few days, while at the surface, flow remains out of the northeast as Fiona moves near Bermuda.
214 AM PDT Fri Sep 23 2022 Fair weather and a warming trend is expected this weekend as high pressure strengthens over the region.
648 AM EDT Fri Sep 23 2022 High pressure will extend across the area today and move off to the east on Saturday.
High pressure in the mid levels will flatten some today.
555 AM CDT Fri Sep 23 2022 (Today through Saturday Night) Issued at 407 AM CDT Fri Sep 23 2022 An upper ridge continues to be centered over Texas this morning and northwest flow is over the Great Lakes. Also, an upper low is located in the northern Plains. The upper low will track along the Canadian border today and tonight and through the Great Lakes Saturday. The upper ridge will shift westward Saturday and Saturday night toward the Four Corners region. Drier air is over the region with dew points mainly in the lower to mid 50s. High pressure will be over the area today but a cold front will move from the Plains toward Arkansas tonight. Lows tonight will be in the lower 60s to around 70 degrees and in the lower 60s to lower 70s Saturday night.
653 AM EDT Fri Sep 23 2022 Cooler and drier high pressure will build into the area through tonight as the cold front moves well away from the area. Fair weather will continue Saturday with dry high pressure remaining over the region.
Dry weather with warmer interior daytime temperatures are forecast through the weekend. Highs are forecast to peak in the lower to mid 90s for most valleys.
621 AM CDT Fri Sep 23 2022 (Today and Tonight) Above normal temperatures will persist across the area again today, as upper level high pressure resides over the area.
629 AM CDT Fri Sep 23 2022 An upper level trough currently located over the Northern Great Plains will push eastward today bringing a chance for showers across our area today. Highs will vary across Kansas with portions of south-central and central Kansas seeing highs in the 70s and 80s while highs may reach the low 90s in far southern Kansas. Temperatures should rebound with highs in the mid 80s in central Kansas and highs in the low into the low 90s.
630 AM CDT Fri Sep 23 2022 (Today through Saturday afternoon) Temperatures will remain warm with widespread 80s and 90s over the next few days thanks to persistent ridging overhead and above- normal boundary layer temps. Drier low-levels will aid in radiational cooling patterns for the overnight time frames leading to "cooler" mornings with more lows in the 60s with 50s across the northern tier of Lea and the high terrain above 4000ft. We'll see a slow expansion of the ridge to the east with the center displaced over N TX instead of the Rio Concho by Sat, but this will have little effect on the ambient weather pattern.
08/DML High pressure at the surface and aloft will linger over the region through Saturday.
417 AM CDT Fri Sep 23 2022 Upper level low pressure will track eastward across the Northern Plains today. A cold front will move southeast across the area this morning on the backside of the system. Temperatures will actually be warmer today behind the front. High temperatures will be a few degrees warmer with another day of deep mixing. By mid to late week, the flow will decrease as upper level ridging builds eastward from the Rockies ahead of a long wave trough progressing eastward into the Pacific northwest and western Canada.
555 AM CDT Fri Sep 23 2022 (Today through Saturday) Cool start to the morning so far with a few areas already in the upper 40s, and most of the mid state in the low to mid 50s. Westerly winds around 10 mph will mix the low levels a bit, and dewpoints should get down to the low 40s and even upper 30s.
546 AM CDT Fri Sep 23 2022 High pressure at the surface and aloft will linger over the region through Saturday.
(Rest of Today) Northeast flow is advecting cool and drier air into the the region this morning thanks to a high pressure cell over northwest Indiana. Temperatures will climb into the lower 70s by midday and into the mid to upper 70s for afternoon highs.
802 AM EDT Fri Sep 23 2022 Cooler and drier high pressure will build into the area through tonight as the cold front moves well away from the area. Fair weather will continue Saturday with dry high pressure remaining over the region.
While the wind shift indicating a weak cold front appears to have progressed as far south as Interstate 10 over southeast Louisiana, any significant cooler/drier air appears to be lagging well to the north, much closer to Interstate 20. That should keep much of the area in the lower and middle 90s for highs.
121 PM EDT Fri Sep 23 2022 High pressure will settle across the central Appalachians through tonight.
(This evening through Saturday Night) More record breaking heat will be possible tomorrow afternoon even with the deep/strong ridge weakening a bit. With slightly better onshore winds setting up tomorrow, there is a very slight chance of isolated showers for the far SW parts of the CWA (mainly in and around Matagorda Bay) as low-level moisture be- gins to pool across the Middle and Lower TX coasts (in response to the passage of an inverted trough).
High pressure continues to build across the region into the weekend with dry conditions and a gradual warming trend. Temperatures are running a few degrees warmer than 24 hours ago in most urban areas and 5-15 degrees warmer in the hills. In addition, Fort Ord and Bodega Bay profilers indicate an surge of drier air at the low levels (below 5000 feet). This is expected as we have high pressure building into the Great Basin, bringing warmer temperatures and drier conditions.
The exception is northeast Mississippi where there is more sun than clouds allowing temperatures to warm into the low 70s. Unfortunately, warmer temperatures are expected to return over the weekend.
An occluded low pressure system continues to spin over the Dakotas this afternoon. Isolated rain chances continue with light showers along and behind a surface pressure trough over south central to southeast North Dakota as well as near the center of the low over north central North Dakota. Precipitation chances wane late this evening while the upper low phases with the jet stream aloft and exits east. There is still reasonable confidence in near or above normal temperatures mid-week as the broad ridge shifts east, but the strength of the multiple waves depicted in deterministic guidance will impact the degree of warming on any day.
High pressure will build across the state beginning Saturday. This will bring a return to dry conditions, with drier air producing chilly overnights and warmer afternoons.
1156 AM CDT Fri Sep 23 2022 (Now through Saturday) Mid-level ridging centered over Texas will continue to provide subsidence across Deep South Texas through much of the period. However, a 500mb inverted trough over the Southwest Gulf of Mexico will under cut the ridge as this feature moves westward towards the Northeast Mexican Coast. At the surface, high pressure across the Gulf of Mexico will maintain light to moderate east to southeast winds. Highs today and Saturday will range from the 80s at the beaches, the lower 90s near the coast and the mid to upper 90s farther inland.
(through Saturday) High pressure centered to the north this afternoon will build further south toward the area Tonight, which will push the cold front into south FL. A trough has formed along the coast, which is helping to enhance onshore winds at the beaches. This trough will likely remain in place through the night keeping winds gusty at the beaches. A few showers will be possible over north central FL this afternoon and evening, due to convergence and moisture associated with coastal trough. Due to the onshore flow, lows Tonight will have a wide variation with readings falling into the upper 50s over inland SE GA, while holding in the lower 70s at the coast. The high will build more toward the northeast during the day on Saturday.
Little change is expected through the short term, as the upper ridge will continue to dominate the weather pattern across the area, with associated subsidence yielding continued dry conditions for Southeast New Mexico and West Texas. Tonight, clear skies and light winds will lend to efficient radiational cooling, with lows once again expected to drop into the lower to middle 60s, with middle to upper 50s possible across the higher terrain and portions of Southeast New Mexico and the northwestern Permian Basin. Despite the ridge aloft flattening by Saturday due to passing troughs to the north, temperatures will remain fairly stable, though may be a degree or two warmer than today, with highs in the lower to middle 90s across the lower terrain and upper 80s in the mountains.
147 PM EDT Fri Sep 23 2022 Drier conditions and cooler temperatures will persist through Saturday.
236 PM CDT Fri Sep 23 2022 Through the weekend, broad upper ridging will retrograde to the west and become highly amplified as a significant upper trough digs across the Midwest and into the Great Lakes area.
It will remain on the very warm side - temperatures are likely to be about the same as today or a smidge warmer, with 90s common during the mid to late afternoon.
With high pressure in control, the end result will be a clear, calm, and dry night as temperatures fall into the mid to upper 50s by early Saturday morning.
As the low level wind profile continues to veer, rain showers will become more focused across portions of MO, leaving the area dry this evening.
258 PM MDT Fri Sep 23 2022 The mid-level trough to the north was moving to the upper Midwest this afternoon while high pressure began to build over the eastern Pacific.
A significant warming trend will develop across the region as high pressure expands into the Southwestern States. Most of the warming temperatures today were across inland areas as there was a light onshore trend that kept areas closer to the coast similar or even cooler than yesterday.
1219 PM CDT Fri Sep 23 2022 (Today and tonight) Upper troughing over the northern Rockies will continue to shift southeastward today, helping flatten the persistent upper ridge anchored over Texas. A warmer day is therefore expected as drier air is pulled northward across the region. Even as the upper ridge begins flattening, continued elevated thickness values with dry SSW surface flow will boost temperatures 5-10 degrees above seasonal averages this afternoon. A narrow plume of midlevel moisture stretched along the top of the ridge in tandem with the passage of a mild upper vort max may generate a few light sprinkles across the southern Panhandle near dawn Saturday.
Scattered showers near and north of the Highway 54 corridor today.
Weak high pressure building into the Deep South with lower dew point airmass filtering into N FL then C FL Saturday for more comfortable feels like temps. High pressure building into the region will keep northeast winds across the waters with evening surges possible through the weekend.
Although we did see a "cold front" this morning, afternoon high temperatures were still able to reach the upper 80s to low 90s for everyone today. As high pressure continues to be the dominant feature, this heat will continue.
124 PM EDT Fri Sep 23 2022 Roller coaster of temperatures in store, reaching the peak Saturday before trending cooler.
209 PM MDT Fri Sep 23 2022 Upper low responsible for recent wet weather continues to depart to the east and skies have cleared across nearly all of southeast MT as of 2pm. Otherwise, heights will gradually rise and dry weather will persist over the next 36 hours, downstream of ridge axis along the Pacific coast. Temps tomorrow will be similar to today with highs in the low-mid 70s most places. Lighter winds anticipated Saturday night, which should be the cooler of the next two nights. The weather will continue to be dominated by a strong upper-level ridge over the western US.
