Generally a rinse and repeat forecast today as high pressure sticks around through the daylight hours. Upper ridging and high pressure will eventually slide east marking the transition to more quasi-zonal flow aloft as upper troughing deepens to our north. An upper level speed max and mid-level disturbances will round the base of the deepening trough owing to another frontal passage and the chance for some rain on Sunday. High temperatures on Sunday will range from the low 80s across North GA to near 90 across south- central GA.
A fairly nice day today as high pressure shifts to our east. This will be in advance of a cold front that will be moving into the area by Sunday night. Adjusted highs a touch in in the north as the clouds and rain may keep the temperatures a bit cooler than guidance. Meanwhile, areas in the south may be a degree or tow warmer than guidance as rain may not move in here until late afternoon.
330 AM EDT Sat Sep 24 2022 High pressure should maintain dry weather today, though an increase in clouds is expected. Rain chances return tonight and Sunday with low pressure. Warmer high temperatures are expected today, though readings should still be around 5 degrees below average.
At the surface, a weak warm front will also lift northeastward through the CWA late tonight, leading to veering of winds with time through most of the lower troposphere. On Saturday morning, the warm front is expected to be shortly followed by a cold front passing trough the CWA. Pfahler By Sunday, the upper-level trough is progged to become closed and nearly stationary over Ontario/Quebec, downstream of an upper-level ridge across much of the western CONUS. Post-frontal low-level CAA throughout Sunday in the wake of Saturday night's cold front is expected to cool 850-hPa temps into the low-10s C, yielding cooler, seasonable high temps in the mid-70s to low-80s F with abundant insolation and deep mixing.
Increased cloud cover and a few degrees warmer today with an outside chance of showers mainly north of I-40 and along the Plateau and Appalachians. Because of the placement of the high and the flow, cloud cover has increased overnight and showers have developed north of us over much of the Ohio Valley. As a result, temperatures will be a bit warmer today with low 80s in the Valley south of I-40.
The lighter winds overnight combined with a fairly dry airmass will allow for strong radiational cooling, with lows mostly in the 40s expected over the plains and upper 20s and 30s in the high country. High temperatures will likely be a degree or two warmer than today, with another day of sun-filled skies. Issued at 1:48 PM MDT Fri Sep 23 2022 Saturday night and Sunday, an upper level trough of low pressure will cover the Central and Eastern U. with an upper level ridge of high pressure over the Western U. This pattern will allow a dry cold front to push across Northeastern Colorado Saturday night resulting in cooler temperatures across the plains on Sunday.
(This afternoon through Saturday) The normal to slightly-below-normal temperatures and dry conditions today are courtesy of the cold front passage yesterday and continued advection of low- and mid-level dry air out of the northeast/east. Highs tomorrow will be in the upper 70s to mid-80s across much of the CWA, which will be a tad warmer than today. The upper-level flow over the OH and TN River Valleys will transition from weak ridging today to quasi-zonal flow tomorrow. That said, I do have slight chance PoPs across far northwest GA pre-daybreak Sunday as models indicate increasing troughing over the aforementioned region on Saturday night and additional weak disturbances dropping south over north Georgia.
(This evening through Saturday) Through This Evening: A southern stream lead wave, coupled with a synoptic trough across the Northern Plains/Canadian Prairies, continues to quickly lift across portions of Kansas/Missouri early this afternoon. Apart from the far northern tier of counties (OK/KS border), temperatures have climbed into the low-90s and are expected to reach mid to upper-90s by late afternoon. Tonight: A weak cold front, currently observed across portions of the Oklahoma panhandle, will slowly drift into northern Oklahoma this evening into early Saturday.
(Today and tonight) The region will remain on the eastern side of mid to upper level ridging.
(Today and Tonight) The upper level ridge will remain over the area today, but will shift west of the area later tonight, as an upper level short wave trough drops southeast across the central and northern Plains states. Skies will be mostly sunny areawide, with afternoon highs in the low to mid 90s for most of the area.
Otherwise, a weak cold front will move southward across the region with winds becoming north throughout the day today. At upper levels, a ridge of high pressure over the western states coupled with a deepening trof across the eastern states will result in dry northwest flow today through Sunday night.
An upper ridge will then move eastward into the Northern Rockies tonight into Sunday night. This ridge will bring mostly to partly sunny skies, dry weather, and light winds to the area.
157 AM EDT Sat Sep 24 2022 High pressure will extend across the area today and move off to the east on Saturday. A cold front will cross the region Sunday. 01 given the amount of dry air in the low levels. This supports a slight chance for thunderstorms through the overnight hours as the cold front moves through Sunday morning.
The clear and dry conditions come courtesy of a strong upper level ridge now building over the area from the south. This ridge will build into Sunday, then slowly weaken as a long wave trough approaches the coast.
(Today through Sunday) This weekend, an inverted trough lingers from northeastern Mexico to over southern into central Texas, an upper level trough deepens east of the Rockies and an upper level ridge builds west of the Rockies. A surface to lower level ridge drifts off to the east today, then a cold front approaches our area late on Sunday.
315 AM CDT Sat Sep 24 2022 The upper level trough that brought rainy and cloudy weather to our region has moved off to the east. Highs today will return to the upper 80s and mid 90s across the region out ahead of a final piece of energy that will be dropping south and rounding the trough off to our east.
SW return flow increases through the day, so look for a warmer breeze to push our temps back to near climo this afternoon, and even a bit above normal tonight. Tonight another upper wave digs into the Upper Midwest, and starts to drive a cold front SE toward the Ohio Valley. Low pressure at the sfc and aloft will be positioned over the Great Lakes at 12z Sunday, with a sfc cold front draped southwest through the Ohio Valley. The sfc cold front is forecast to push through central KY and southern IN during the first half of the day, but will only bring spotty light rain. Temperatures will max out in the mid 70s to around 80 degrees on Sunday before cooler air pours in behind the front.
Ridging will amplify over the area today, leaving us with another day of dry and stable weather.
1231 AM EDT Sat Sep 24 2022 Cool high pressure will persist through the weekend.
KED Water vapor imagery currently shows an upper low situated over northern ND/southwest Manitoba with upper ridging spanning across central/southern TX. At the surface, ridging is centered over the Ohio Valley with some return flow across the Plains. A warm front extends from far southwest KS into western OK. One final piece of energy is forecast to dive down the backside of the trough Sat night and will allow the upper trough to finally start to push east. In addition, this will bring another shot of cooler/drier air for Sun. Deep upper trough will encompass the eastern CONUS to start the work week with strong northwest flow across the Plains. A weak cold front will move southward across central and southern Kansas later on Saturday.
Currently - High pressure has pushed southeastward into the eastern United States as Hurricane Fiona lifts rapidly northward into northeastern Canada. This high has pushed an early season front southward into Central Florida. The Keys are just beginning to feel the effects of the high with light winds shifting northeast to east. Some drier air ahead of the front has dropped dew points in the Keys into the lower 70s. Short Term Update - The high pressure over the eastern United States will build further southeastward off the mid Atlantic coast through the overnight period. Expect overnight lows in the lower 80s, dew points remaining in the lower 70s under mostly clear to partly cloudy skies.
More significant shower activity is expected tonight as an upper trough approaches and 850 mb warm advection and convergence increase. Temperatures will be around 10 degrees cooler than normal.
(Today and tonight) Upper level ridging over Texas will continue to flatten and shift westward today in response to broadening troughing over the Great Lakes region.
(Today through Sunday afternoon) The region continues to be under the influence of mid-level ridging aloft with broad expansion across the Lone Star state according to latest Upper Air analysis and WV satellite. Temperatures will remain on the warm side with 80s over the high terrain, 90s for a majority of the area, and even some 100+ located down in the RGV.
The clouds and showers will be out of our area by noon and the rest of the day should be sunny and on the warm side of the normal range with highs reaching into the low to mid 70s.
A stronger trough seen early this afternoon on water vapor imagery across the Dakotas will approach this evening. Additional scattered showers may develop during the day on Saturday as another trough rotates southward into the evolving longwave trough. High temps will depend on how the low clouds evolve with mid 60s to low 70s for much of the region with enough clearing, but these temps may be optimistic if low clouds persist for more of the day.
453 AM EDT Sat Sep 24 2022 A ridge aloft extending eastward toward Florida flattens out through the weekend as troughing builds over the southeast. At the surface, a frontal boundary remains stalled across the southern peninsula, with high pressure centered near the Carolinas.
The Tri-State area can expect temperatures to reach into the 80s Saturday but Sunday is expected to be cooler, only reaching into the mid 70s to low 80s. The cooler temperatures will be possible due to better mixing and a slightly lower dew point Saturday night.
1130 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.
1238 AM CDT Sat Sep 24 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. While the parent trough will remain well to our north, an impulse rounding its base will drive a cold front through the area on Sunday with a cooler and significantly drier air mass in its wake -- dry enough to necessitate lowering initialized NBM values by several degrees. Resultant instability will be on the higher side with CAPE values either side of 2000 J/kg. Forecast soundings show steep lapse rates in the lower troposphere with notably large dewpoint depressions.
Dry weather will accompany the warmer temperatures through the end of the week. High pressure will build over the west coast over the next few days bringing clear skies and above normal temperatures for the region. Max temps seem to reach a peak on Sunday with much of the lower valley seeing temperatures in the mid-upper 90's.
Sunday will start with clear skies and see temps climb into the 60s across the region with breezy NW winds as pressure gradient force increases and winds respond to high pressure building into the western high plains.
Quigley (Tonight through Saturday night) Ridging overhead will gradually weaken through the short term, with H5 heights falling from 592 dm to 588 dm by 12Z Sunday. Visible satellite imagery depicts a somewhat denser cu field today across much of the region, but with ample sunshine and soils continuing to dry back out we'll see another warmer than normal afternoon as highs will top out in the 90s for most locations, with a few spots sneaking into the triple digits near and east of I-35, potentially for the final time in 2022. With the weakening of the ridge and some slightly higher dew points in the afternoon, temperatures tomorrow should be a couple degrees cooler relative to today but still warmer than seasonal normals.
(Now through Sunday) Broad and weak 500 mb low pressure will be the dominant feature over the BRO CWFA during the period.
1215 AM EDT Sat Sep 24 2022 High pressure should maintain dry weather through Saturday. Rain chances return Saturday night and Sunday with low pressure. As the aforementioned low pressure continues to deepen over Lake Superior, return wsw flow should invoke warm, moist advection and support an increase in both temperature and cloud cover Saturday. Model ensembles indicate a trough is expected to persist across the Eastern CONUS through much of the upcoming week. Long range solutions begin to disagree somewhat thereafter given the track uncertainty of Tropical Depression Nine, but current guidance suggests the forecast area may reside within upper ridging and nwly flow, creating dry conditions and slowly moderating (but seasonably cool) temperature. The approach of an upper level trough will promote moist advection resulting in increasing cirrus overnight and mid-level decks Saturday.
259 AM EDT Sat Sep 24 2022 Cloudy skies across the region early this morning with pockets of showers as the lower levels of the atmosphere steadily moisten. Upper low currently over the upper Midwest will strengthen and track into the Great Lakes through tonight. it will carve out a deeper upper trough across the eastern half of the country. As moisture advects south into central Indiana tonight with the strengthening of the upper low. Could see some sporadic gusts approaching 20mph this afternoon as a weak surface wave tracks across the lower Great Lakes.
632 AM CDT Sat Sep 24 2022 (This evening through Saturday) Through This Evening: A southern stream lead wave, coupled with a synoptic trough across the Northern Plains/Canadian Prairies, continues to quickly lift across portions of Kansas/Missouri early this afternoon. Apart from the far northern tier of counties (OK/KS border), temperatures have climbed into the low-90s and are expected to reach mid to upper-90s by late afternoon. Tonight: A weak cold front, currently observed across portions of the Oklahoma panhandle, will slowly drift into northern Oklahoma this evening into early Saturday.
A cold front will cross the region on Sunday. This will bring a return to cooler conditions for much of the work week. Still fairly dry in the low levels, but some light measurable precipitation is occurring. Southerly flow and warm air advection on the back side of a high pressure system will allow temperatures to rise back into the lower to mid 70s. This will push a cold front across the region. A broad longwave trough over the eastern half of the U.
TONIGHT: Winds may stay quite breezy through the overnight as the surface pressure gradient remains enhanced as high pressure slides down the Western High Plains. Temperatures fall into the lower 50s with a few scattered cloud hanging around. The region will still be firmly planted under the increased mid-upper wind field associated with sharp northwest flow between upper troughing over Hudson Bay and riding over the Intermountain West. GFS/EC ensembles both support widespread 25-35 mph winds with the highest winds over the east James River areas. Have pushed guidance towards the highest values. All this said, latest GFDI values suggest very high fire danger west of I-29 in the afternoon as high temperatures climb into the lower 70s.
749 AM EDT Sat Sep 24 2022 High pressure should maintain dry weather today, though an increase in clouds is expected. Rain chances return tonight and Sunday with low pressure. Warmer high temperatures are expected today, though readings should still be around 5 degrees below average.
620 AM EDT Sat Sep 24 2022 (Today and tonight) The region will remain on the eastern side of mid to upper level ridging.
649 AM CDT Sat Sep 24 2022 (Today through Sunday Night) An upper ridge continues over the southern U. this morning with an upper trough over the Midwest. The high will shift to the western U. tonight and the upper trough will dip into the central and eastern states and this will continue on Sunday. A warm front will move into the state this morning. This will bring moisture and warmer temperatures to the area today ahead of the next cold front in the Plains. The cold front will move into north Arkansas late tonight and clear the southern border by Sunday evening.
532 AM EDT Sat Sep 24 2022 High pressure should maintain dry weather today, though an increase in clouds is expected. Rain chances return tonight and Sunday with low pressure. Warmer high temperatures are expected today, though readings should still be around 5 degrees below average.
Dry weather with warmer interior daytime temperatures are forecast through the weekend.
514 AM MDT Sat Sep 24 2022 Clear skies this morning along with a very dry air mass has led to efficient radiational cooling as temperatures are much cooler than they were yesterday. Just a signal that with the turn to autumn and a robust west to east oriented jet, any robust moisture surge we receive is not sticking around to long and quick to exit after a deep enough trough sweeps it out of here. The aforementioned upper level jet will relax today as a ridge of high pressure builds across the Great Basin with the ridge axis arcing up into the Intermountain West. By Sunday, high pressure remains parked out west and slides ever so slightly eastward.
555 AM CDT Sat Sep 24 2022 (Today through Sunday) This weekend, an inverted trough lingers from northeastern Mexico to over southern into central Texas, an upper level trough deepens east of the Rockies and an upper level ridge builds west of the Rockies. A surface to lower level ridge drifts off to the east today, then a cold front approaches our area late on Sunday.
625 AM CDT Sat Sep 24 2022 (Today and tonight) Upper level ridging over Texas will continue to flatten and shift westward today in response to broadening troughing over the Great Lakes region.
614 AM CDT Sat Sep 24 2022 (Now through Sunday) Broad and weak 500 mb low pressure will be the dominant feature over the BRO CWFA during the period.
Above-average temperatures with sunny skies and light winds expected as an area of high pressure continues to build over the region this weekend. Heights will continue to rise over the Desert Southwest this weekend as an area of high pressure builds with its center overhead. The same moisture flux that brought isolated showers and thunderstorms to the lower Colorado River Valley yesterday will once again bring very isolated convection to our southern zones this afternoon.
Drier and warmer weather is expected for this weekend, with isolated storm activity possible in southeastern Arizona. Tranquil weather conditions are currently taking place across northern Arizona this morning as high pressure begins to strengthen over the West. A drying and warming trend is forecast for today and Sunday, thanks to the amplifying ridge and light northerly flow, with isolated shower and storm activity confined to the White Mountains region.
528 AM MDT Sat Sep 24 2022 Upper level ridge extended from the southern Plains to along the Pacific with a upper level trough over The Upper Midwest/western Great Lakes. Sunday will be cooler, mainly east of the Laramie Range with high temperatures in the upper 60s to mid 70s.
Nearly all high-res guidance, indicate dewpoint temperatures in the low 30s and some even lower. Some limiting factors could be the length of time of the lowest RH values combined with the breezy conditions, but this should be watched as the primary concern for today. Another cold front will move through tonight turning winds to the north and ushering in cooler air for Sunday. An anonymously strong upper upper ridge will build into the western half of the CONUS leaving the central Plains under northwesterly flow aloft through the first part of the work week. After that a couple upper level disturbances will break down the ridge and zonal flow will return.
Temperatures managed to fall below 80 degrees for a few select locations along with dew points flirting with the lower 70s. High pressure will settle in across the Mid-Atlantic and southeastern states over the weekend.
Made just a few tweaks to T and Td to better reflect trending on the cooler side this morning (no complaints here!!!). Generally a rinse and repeat forecast today as high pressure sticks around through the daylight hours. Upper ridging and high pressure will eventually slide east marking the transition to more quasi-zonal flow aloft as upper troughing deepens to our north. An upper level speed max and mid-level disturbances will round the base of the deepening trough owing to another frontal passage and the chance for some rain on Sunday. High temperatures on Sunday will range from the low 80s across North GA to near 90 across south- central GA.
Overall benign weather is expected over the next few days as a ridge of high pressure builds into the area. This will bring a warming and drying trend with light east winds over the ridges. Then, a trough of low pressure will move through the area midweek bringing cooler weather back to southern Oregon and northern California, but widespread rain is not likely. The marine stratus should burn off later this morning (if it develops at all), revealing a sunny and warmer afternoon.
555 AM MDT Sat Sep 24 2022 Expect another day of dry, sunny, and warm conditions today with Colorado on the eastern periphery of a strengthening ridge aloft. Temperatures rise into the low 80s for the plains/urban corridor, 60s for the foothills/mountain valleys, and 40s and 50s for the mountains. A weak cold front moves through Saturday evening with moisture/precipitation expected with it. On Sunday, The high pressure ridge axis will be west of Colorado with a moderate northwest flow in place. The airmass will remain dry but cooler conditions expected following a cold front from the evening before.
So, will need to watch this area through the day for training cells, with the highest coverage expected over the Treasure Coast and Okeechobee County through tonight.
655 AM CDT Sat Sep 24 2022 Narrow band of showers continues to push east in front of the trough or wind shift line in NE ND. Westerly winds and upper clouds seem to erode the lower CIGs. Sunday will start with clear skies and see temps climb into the 60s across the region with breezy NW winds as pressure gradient force increases and winds respond to high pressure building into the western high plains.
511 AM CDT Sat Sep 24 2022 Today through tonight: A cold front is expected to begin approaching the forecast area from the north as we go through the weekend. For today, the low level ridge ahead of the front will support temperatures getting well into the 90s under mostly sunny skies, especially over the ArkLaMiss Delta region where heat indices will likely top out near 100 F.
Very tranquil weather can be expected over the coming days as an upper-level ridge builds over southern California, becoming the main synoptic feature for the region.
307 AM MDT Sat Sep 24 2022 Clear skies this morning along with a very dry air mass has led to efficient radiational cooling as temperatures are much cooler than they were yesterday. Just a signal that with the turn to autumn and a robust west to east oriented jet, any robust moisture surge we receive is not sticking around to long and quick to exit after a deep enough trough sweeps it out of here. The aforementioned upper level jet will relax today as a ridge of high pressure builds across the Great Basin with the ridge axis arcing up into the Intermountain West. By Sunday, high pressure remains parked out west and slides ever so slightly eastward.
