445 AM PDT Fri Jun 21 2024 Hot today and then even hotter on Saturday as high pressure builds over the Four Corners region.
Dry and a few degrees warmer today, with increasing clouds in the afternoon. Weak trough energy over the region today will result in some afternoon cumulus cloud build-ups. Trough energy exits east into Utah this evening, leaving a weak near-zonal flow across northern and central NV. High pressure builds in from the south on Saturday which will result in noticeably warmer temperatures across the region, with many locations warming by an additional 4-8 degrees as afternoon highs reach 90s in many areas and even low 100s in some of the lower elevation valleys such as Winnemucca and Battle Mountain.
Models are showing an upper trough over the Great Basin this morning to weaken and move eastward into Colorado by this evening into the overnight hours. There is plenty of CAPE progged for the CWA with the highest amounts over the northern border area.
613 AM CDT Fri Jun 21 2024 A ridge of high pressure will bring mainly rain free weather to the Mid-South through Saturday night with temperatures rising into the middle to upper 90s over the weekend.
Afternoon highs Friday will warm into the upper 80s to the lower 90s, which is near or slightly below normal for this time of year. Subsidence under a building ridge aloft will keep Friday through the weekend rain-free with a warming trend. /Issued 246 AM CDT Fri Jun 21 2024/ /Saturday Onward/ Over the next several days, the upper ridge will propagate westward from its current location across the Ohio Valley, eventually taking up residence over the Desert Southwest by midweek.
A ridge of high pressure will bring mainly rain free weather to the Mid-South through Saturday night with temperatures rising into the middle to upper 90s over the weekend.
609 AM CDT Fri Jun 21 2024 (Friday through Saturday) Quiet weather remains in the forecast to start our weekend, as upper-level ridging slightly bulks up to our east. Given the placement of the high pressure, there is at least some chance that some showers get pushed into our SE zones, so I have introduced some low-end PoPs to account for this chance. /44/ (Saturday Night through Friday) As the ridge builds and shifts west into the weekend, our already hot temperatures will continue to climb.
616 AM CDT Fri Jun 21 2024 (Today) Upper level ridging centered from the mid south region extends back to the west and across the southern plains.
558 AM CDT Fri Jun 21 2024 (Today through Saturday Night) An upper level ridge continues to retrograde west. Some dew points will climb into the lower 70s Saturday increasing the heat indices slightly. Lows tonight will be in the mid 60s to mid 70s and in the lower to mid 70s Saturday night.
Although ridging aloft will continue to expand southwest over the area today, sufficient moisture and modest low level forcing should support some scattered showers or isolated storms with heating by early afternoon.
/NEW/ /Through Saturday Afternoon/ High pressure will continue to build across North and Central Texas through the first half of the weekend. With subsidence in place, temperatures will climb to the lower to mid 90s today and mid 90s tomorrow. /Issued 246 AM CDT Fri Jun 21 2024/ /Saturday Onward/ Over the next several days, the upper ridge will propagate westward from its current location across the Ohio Valley, eventually taking up residence over the Desert Southwest by midweek.
(This afternoon through Saturday) A 596dam ridge is situated over the Tennessee Valley with deep easterly flow across the area. The ridge will slowly shift westward through tomorrow, but temperatures will trend gradually warmer over the next couple of days with highs in the mid to upper 90s under mostly sunny skies.
/Issued 101 PM CDT Fri Jun 21 2024/ /Through Saturday Afternoon/ High pressure will continue to build across North and Central Texas through the first half of the weekend. With subsidence in place, temperatures will climb to the lower to mid 90s today and mid 90s tomorrow.
Strongest sunshine of the year will couple with the heated air mass coming in from the south and temperatures should soar into the lower and middle 90s for elevations in the Southern Hills less than 6000ft and the eastern Magic Valley. The overnight lows on Sat night in the southern hills stay very warm, especially at the inversion top, where they will stay in the 60s, and even the low 70s. As of right now, the low temperatures, high temperatures, and the climatic temperatures have not produced the need for any headlines, although it is very close.
However, warm temperatures will persist across the higher elevations where temperatures will only dip into the upper 60's to upper 70's. Stratus will also return to the region this evening, yet will penetrate less inland overnight as high pressure compresses the marine layer.
An area of low pressure (Invest AL92) near the northeast Florida coast continues to move west-northwest towards the northeast Florida and Georgia coasts. However,the low is expected to continue to move to the north of central Florida with the same impacts expected for east central Florida regardless of development. As the trough axis passes from SE to NW across the area, winds will shift out of the south and southeast during the day and seas will gradually subside below 7 feet offshore by afternoon.
(Rest of Today) High pressure continues to tell the tale across the TN Valley today. The high to the north should nudge this and further weaken the boundary to the south of the area by this afternoon. Highs are forecast to reach the low to mid 90s by the mid-afternoon hours.
(This evening through Saturday) An upper-level ridge centered over Texas is expected to gradually move westward during the short term period. Tomorrow morning, as the ridge becomes more firmly established over the CWA, the southeasterly low-to-mid level flow that has sustained Today's moist environment will begin to slowly become southwesterly. Saturday's morning lows are expected to be mild, but warming from downsloping winds should return high temperatures to the low to mid 90s.
Afternoon temperature maximums will reach the low-to-mid 90s with light easterly winds. /16/ (Friday through Saturday) Quiet weather remains in the forecast to start our weekend, as upper-level ridging slightly bulks up to our east. Given the placement of the high pressure, there is at least some chance that some showers get pushed into our SE zones, so I have introduced some low-end PoPs to account for this chance. /44/ (Saturday Night through Friday) As the ridge builds and shifts west into the weekend, our already hot temperatures will continue to climb.
Temperatures today will be a few degrees warmer than yesterday, but even hotter temperatures will arrive this weekend with locations in the Treasure Valley seeing a 30-70% chance of highs 100F or warmer both days.
(The rest of today) Deep layer ridging continues to spread in from the east today.
1231 PM CDT Fri Jun 21 2024 (Today and tonight) Warmer and drier conditions are expected today under a rebuilding upper-level ridge over West Central Texas.
Tomorrow looks even hotter as the upper ridge remains in place and 850mb temps heat up a tad, so expect highs to be a degree or two above today's readings. Also not anticipating any popups tomorrow due to the strength of the upper ridge, but as always in our summertime regime one or two could occur.
Good setup for severe weather with strong trough overhead, surface CAPES of 1000-2000 J/kg, Bulk Effective Shear 35 to 50 kt and PWAT's around 1 inch with higher values over SE MT.
1231 PM CDT Fri Jun 21 2024 (Today through Saturday) The center of the Subtropical Ridge begins to shift to the southwest toward Texas today. With the Ridge approaching, subsidence is still minimal while a tropically moist airmass remains. The Subtropical Ridge moves nearly overhead on Saturday bringing a subsident airmass while another tropical disturbance deepens over the southwestern Gulf of Mexico. NHC shows a 60% chance of tropical cyclone development.
(This evening through Saturday) Hotter tomorrow with widespread readings of 95 to 100 deg F, with southeastern Oklahoma rising into the low 90's. There remains quite a bit of uncertainty on whether the cold front, which is currently stationary over Nebraska, enters northern Oklahoma late Saturday or stalls north of the KS/OK state line.
Lingering showers/isolated storms this evening will end due to loss of diurnal heating but additional showers could impact mostly coastal areas later tonight as weak coastal troughing develops. Lows tonight should mostly be near to slightly above normal in the lower to mid 70s. Highs Saturday should be a bit warmer as the flow begins to turn southerly, generally ranging from the mid to upper 80s closer to the coast (with peak heat indices in the lower to mid 90s) to lower to mid 90s inland (with peak heat indices near 100 degrees). Mid level ridge will push to the west as a northwest flow develops across our area through early week.
With a trough exiting the region, mid and upper level stability has increased through the day, while the sunshine has warmed and destabilized the lower levels. Once the storms move east of the Continental Divide and catch up with the upper level trough, they will blossom into much stronger storms.
1220 PM CDT Fri Jun 21 2024 A ridge of high pressure will bring mainly rain free weather to the Mid-South through Saturday night with temperatures rising into the middle to upper 90s over the weekend.
301 PM CDT Fri Jun 21 2024 Tonight and Saturday: Deep layer ridging will continue over our region during the near term. The combination of high pressure ridging and a persistent dry airmass will keep our weather relatively dry through the end of this weekend.
(Tonight) Dry conditions are expected overnight as ridge continues to drift southwestward across the local area.
1221 PM CDT Fri Jun 21 2024 (The rest of today) Deep layer ridging continues to spread in from the east today.
1251 PM CDT Fri Jun 21 2024 (Today through Saturday Night) An upper level ridge continues to retrograde west. Some dew points will climb into the lower 70s Saturday increasing the heat indices slightly. Lows tonight will be in the mid 60s to mid 70s and in the lower to mid 70s Saturday night.
Unlike the past few days an upper level ridge, currently located over the Tennessee Valley, has started to build in across central Texas. This feature should help to suppress most chances for rain today and tomorrow and allow warmer temperatures to occur. A high pressure system will develop across the southwestern U.
(Tonight through Saturday night) Upper air analysis this morning showed a high centered over TN with a ridge axis extending back over TX into northern Mexico. High pressure at the center is centered over northeastern TX and winds across our CWA were mostly from the east. The upper ridge will push back toward the west through this period. A little less cloudiness tonight will allow temperatures to be a few degrees cooler than they were this morning. High temperatures Saturday will be a few degrees warmer than today getting back to near normal.
1158 AM CDT Fri Jun 21 2024 (Rest of Today) High pressure continues to tell the tale across the TN Valley today. The high to the north should nudge this and further weaken the boundary to the south of the area by this afternoon. Highs are forecast to reach the low to mid 90s by the mid-afternoon hours.
Surface ridging currently over the Mid-South will continue to gradually shift eastward across the Mississippi River into the Southern Great Plains by tomorrow afternoon, boosting temperature maximums/minimums into the upper 90s/mid-to-upper 70s.
Unlike the past few days an upper level ridge, currently located over the Tennessee Valley, has started to build in across central Texas. This feature should help to suppress most chances for rain today and tomorrow and allow warmer temperatures to occur.
(Thru Tonight) A quiet afternoon and night is in store with ridging aloft in control. Lows should be a touch cooler with less cloud cover around overnight. A low level thermal ridge over the central High Plains will expand east ahead of the boundary, allowing afternoon highs to climb into the low to mid 90s.
Temperatures will rise to around 10 to 15 degrees above average this weekend with widespread triple digit afternoon highs across the lower elevations.
1221 PM CDT Fri Jun 21 2024 (Today and tonight) The upper level high currently positioned over the ArkLaTex region will continue its westward progression into the South Plains region through the short-term period. As this high pushes closer to the region, expect thickness values to rise, influencing warmer temperatures than previous. Therefore, temperatures will remain cooler across areas where shower activity and cloud cover is expected, i. While areas elsewhere, can expect warmer temperatures in the upper 80s to low 90s as skies begin to clear. Shower activity is expected to come to an end by the evening hours as the upper level high expands over the region.
Expect much of the local area to remain dry tonight through Saturday as high pressure remains in control of the weather.
616 PM CDT Fri Jun 21 2024 (This evening through Saturday) An upper-level ridge centered over Texas is expected to gradually move westward during the short term period. Tomorrow morning, as the ridge becomes more firmly established over the CWA, the southeasterly low-to-mid level flow that has sustained Today's moist environment will begin to slowly become southwesterly. Saturday's morning lows are expected to be mild, but warming from downsloping winds should return high temperatures to the low to mid 90s.
633 PM CDT Fri Jun 21 2024 Tonight and Saturday: Deep layer ridging will continue over our region during the near term. The combination of high pressure ridging and a persistent dry airmass will keep our weather relatively dry through the end of this weekend.
545 PM CDT Fri Jun 21 2024 (Tonight) Dry conditions are expected overnight as ridge continues to drift southwestward across the local area.
/NEW/ /Tonight through Saturday Night/ Mid level ridging will continue to build across the Southern Plains through Saturday with hot and dry conditions expected.
553 PM CDT Fri Jun 21 2024 (Thru Tonight) A quiet afternoon and night is in store with ridging aloft in control. Lows should be a touch cooler with less cloud cover around overnight. A low level thermal ridge over the central High Plains will expand east ahead of the boundary, allowing afternoon highs to climb into the low to mid 90s.
Synoptic setup remains more or less the same, with an extension of upper high pressure across the Carolinas extended up out of the Deep South. Over the next 24 hours, the center of the upper anticyclone will shift slowly off to the SW, but will remain close enough to keep a light NW to N flow across the region at mid/upper levels. Expect a few showers to develop over the higher terrain as indicated in some of the CAMs, which will be carried over from the previous forecast. High temps will be about three degrees warmer than Friday, but even with the increase in dewpoint, the apparent temp should stay well short of Advisory criteria.
952 PM CDT Fri Jun 21 2024 (This evening through Saturday) Hotter tomorrow with widespread readings of 95 to 100 deg F, with southeastern Oklahoma rising into the low 90's. There remains quite a bit of uncertainty on whether the cold front, which is currently stationary over Nebraska, enters northern Oklahoma late Saturday or stalls north of the KS/OK state line.
Fairly quiet weather on tap this afternoon through early Saturday a a weak trough exits the region. Saturday afternoon and night, low pressure moves into the BC coast from the north Pacific and troughing digs across the Pacnw.
607 PM CDT Fri Jun 21 2024 (This evening through Saturday) Hotter tomorrow with widespread readings of 95 to 100 deg F, with southeastern Oklahoma rising into the low 90's. There remains quite a bit of uncertainty on whether the cold front, which is currently stationary over Nebraska, enters northern Oklahoma late Saturday or stalls north of the KS/OK state line.
754 PM CDT Fri Jun 21 2024 (This evening through Saturday night) Impressively strong upper level ridge centered around TN encompasses nearly 2/3's of the country. The ridge has been and will continue to drive drier air into the region as the afternoon and evening progresses. Models show the center of the broad ridge to be just north of the CWA midday Saturday.
Temperatures are warm currently in the 80s which is about 2-5 degrees warmer than yesterday this time. Temperatures will remain warm tonight falling into the low to mid 70s. Tomorrow looks even hotter as the upper ridge remains in place and 850mb temps heat up a tad, so expect highs to be a degree or two above today's readings. Also not anticipating any popups tomorrow due to the strength of the upper ridge, but as always in our summertime regime one or two could occur.
A few factors greatly hindered our convection today: the low stratus w/ capping, dry mid level air in our west, and a lack of forcing. Good setup for severe weather with strong trough overhead, surface CAPES of 1000-2000 J/kg, Bulk Effective Shear 35 to 50 kt and PWAT's around 1 inch with higher values over SE MT. Arthur Upper level ridging will settle in over the Northern Rockies on Saturday, resulting in hot and dry conditions with several locations nearing record highs.
Ridging at the sfc & aloft continue to build in, with RAP/evening 00Z upper air analysis indicate 595DM H5 ridge centered over the the Mid-South. /DC/ Tonight and Saturday: Deep layer ridging will continue over our region during the near term. The combination of high pressure ridging and a persistent dry airmass will keep our weather relatively dry through the end of this weekend.
Synoptic setup remains unchanged with deep upper anticyclone centered over the Mississippi Valley and extending well into the Mid-Atlantic. Over the next 24 hours, the center of the upper anticyclone will shift slowly off to the SW, but will remain close enough to keep a light NW to N flow across the region at mid/upper levels. Expect a few showers to develop over the higher terrain as indicated in some of the CAMs, which will be carried over from the previous forecast. High temps will be about three degrees warmer than Friday, but even with the increase in dewpoint, the apparent temp should stay well short of Advisory criteria.
(Tonight) A strong ridge of high pressure at the sfc remains layered across much of the region, as lingering clouds continue to diminish this Fri evening. Current temp trends are mainly in the lower/mid 80s although with dew pts in the mid 60s/near 70F, overnight lows look to fall predom into the upper 60s/lower 70s for most spots. Otherwise, mostly clear/quiet wx conditions look to prevail into the daytime hrs Sat as high pressure remains intact over the mid TN Valley.
Looks like the ridge is going to win out of the weak disturbance that is currently in southeastern Georgia.
1221 AM CDT Sat Jun 22 2024 (Tonight through Saturday night) Upper air analysis this morning showed a high centered over TN with a ridge axis extending back over TX into northern Mexico. High pressure at the center is centered over northeastern TX and winds across our CWA were mostly from the east. The upper ridge will push back toward the west through this period. A little less cloudiness tonight will allow temperatures to be a few degrees cooler than they were this morning. High temperatures Saturday will be a few degrees warmer than today getting back to near normal.
A large upper level ridge remains across much of the Southeast with high pressure sitting underneath this ridge. Forecast highs this afternoon will once again rise into the low to mid 90s.
131 AM EDT Sat Jun 22 2024 Moisture will increase across the area over the weekend as low pressure approaches from offshore.
/NEW/ /Overnight through Saturday night/ Isolated showers that formed on the southern periphery of a ridge aloft have dissipated with the loss of surface heating. After a seasonably hot and humid day with highs in the lower and middle 90s, temperatures will cool steadily overnight, reaching the lower and middle 70s by sunrise Saturday. Temperatures will be slightly warmer on Saturday (highs generally in the middle 90s) with building heights and plenty of sun. Overnight lows will be mainly in the lower and middle 70s, but a few spots across the urban heat island of the metroplex may not fall below 78 degrees. A stout 597dam upper ridge currently centered over the Tennessee River Valley will shift westward over the next several days.
(Today and tonight) High pressure continues to slowly build back over West Central Texas, which will generally bring warmer and drier conditions to the area.
226 AM MDT Sat Jun 22 2024 - The overall weather pattern will begin to trend towards a warmer and drier one starting today. The weekend starts pleasant with seasonable temperatures and mostly clear skies, as a potent area of high pressure builds back into the region.
(Today through Sunday afternoon) The warmer and drier trend will continue into today. Upper ridging continues to retrograde west across the region and strong subsidence will keep any chance for rain in the Davis Mountains if we even see that.
Strong high pressure, both at the surface and aloft, will remain in control of the weather across the region through tonight. Then for tonight, mostly clear skies will exist as lows fall into the low and middle 70s.
(Thru Tonight) A quiet afternoon and night is in store with ridging aloft in control. Lows should be a touch cooler with less cloud cover around overnight.
1226 AM CDT Sat Jun 22 2024 (This evening through Saturday) An upper-level ridge centered over Texas is expected to gradually move westward during the short term period. Tomorrow morning, as the ridge becomes more firmly established over the CWA, the southeasterly low-to-mid level flow that has sustained Today's moist environment will begin to slowly become southwesterly. Saturday's morning lows are expected to be mild, but warming from downsloping winds should return high temperatures to the low to mid 90s.
(Today through Sunday Night) An upper level ridge will be over Arkansas today and centered over Texas on Sunday. A cold front will be able to move into north Arkansas Sunday afternoon. Highs today will be in the upper 80s to mid 90s and Sunday will be in the lower 90s to near 100 degrees. Some dew points will climb into the lower 70s Sunday, increasing the heat indices slightly. Lows tonight will be in the lower to mid 70s and in the 70s Sunday night.
Mid-level ridging over the ArkLaTex will act to hold this axis of deeper moisture over the state through the weekend. Showers are ongoing to the north of Cape Canaveral, and this trend should continue over the next few hours as we reside just south of weak low pressure.
(Today through Sunday) The center of the Subtropical Ridge drifts to the west over Texas today and Sunday while another tropical disturbance approaches the northeastern Mexico coast on Sunday. NHC has a 50% chance of tropical cyclone development. The airmass is subsident underneath the Ridge with most areas remaining rain free.
(Today through Sunday) A strong 596 DAM H5 ridge stretches from the Tennessee River Valley westward to the TX Panhandle this morning. At the surface, high pressure will be in control and should continue to limit surface winds across the region. With higher heights and thicknesses, expect above average temperatures with most locations climbing into the middle and upper 90s with heat index values warming into the lower to mid 100s or just shy of heat advisory thresholds.
Offsetting a more significant increase in temperatures, especially for western and northern parts of Oklahoma, will be continued redevelopment of mid/high level cloud cover within plume of elevated moisture ahead of northern/central plains upper level trough. Attention then turns toward weak frontal boundary that pushes into northern Oklahoma late today/tonight in response to the passing central plains trough.
