421 AM CDT Mon Jul 1 2024 Today and Tonight: The upper-level ridge centered over East Texas this morning is analyzed around 596 dam at 500mb - or near max values for this time of year. Subsidence beneath this ridge will be the main driver again for dangerous heat across the Gulf Coast region today, but at least some drier air is moving into parts of our forecast area behind a weak cold front.
645 AM EDT Mon Jul 1 2024 High pressure builds in today with dry conditions expected for the first half of the week.
Slightly cooler air temps wl also be noted, w/ aftn readings in the mid to upper 80s for most areas, while Wrn to S/Wrn and Srn AR wl still see near-normal temps in the low 90s.
724 AM EDT Mon Jul 1 2024 High pressure will provide dry and comfortable weather for the first half of the week before an unsettled pattern takes hold to close out the week. ------------------------------------------------------------------- Slow height rises aloft and building high pressure will provide dry and comfortable conditions with lots of sunshine.
Temperatures will be in the upper 70s inland to the low 80s along the coast.
(Now through Tuesday) An upper level ridge will remain centered west of the area through Monday. A weak frontal boundary will sink toward the coast this afternoon resulting in the highest rain chances near the coast. Highs on Tuesday will range from the low 90s east of I-65 to mid and upper 90s west of I-65.
634 AM EDT Mon Jul 1 2024 High pressure and a cooler, drier airmass will remain in place across the region today. It will be cooler and drier. Ridging will still extend back into the middle Ohio Valley. Meanwhile, mid level ridging will build into the Great Lakes and Ohio Valley. Some high clouds will filter through the mid level ridge, allowing skies to vary between mostly clear and partly cloudy. Meanwhile, the mid level ridge will extend from the lower Ohio Valley northeast into the central/eastern Great Lakes.
700 AM EDT Mon Jul 1 2024 Cooler and drier air works into the region today behind a departing cold front.
739 AM EDT Mon Jul 1 2024 (Today through Tuesday) Monday will be warm and unsettled as a mid-level trough lingers over the region. At the surface, South Florida remains on the periphery of Atlantic high pressure with the ridge axis sitting around Lake Okeechobee. Mid-level high pressure begins to slide east from the southern plains towards the southeastern United States on Tuesday. The high will not build all the way into southern Florida, therefore allowing the unsettled, diurnally-driven storm pattern to continue for another day with a southeasterly wind flow.
620 AM CDT Mon Jul 1 2024 Today and Tonight: The upper-level ridge centered over East Texas this morning is analyzed around 596 dam at 500mb - or near max values for this time of year. Subsidence beneath this ridge will be the main driver again for dangerous heat across the Gulf Coast region today, but at least some drier air is moving into parts of our forecast area behind a weak cold front.
However, dew points have dropped into the 60s throughout much of the area already this morning and are expected to continue to fall into the upper 50s this afternoon- allowing it to feel much cooler than the past few days.
545 AM MDT Mon Jul 1 2024 Aviation Section Updated Expect unsettled weather to continue through midweek this week as broad upper level troughing remains in place, bringing daily chances for afternoon showers and thunderstorms across the area. A significant warm up is possible later this week as upper level ridging builds across the Western United States.
642 AM EDT Mon Jul 1 2024 High pressure builds in from the Great Lakes today, bringing less humid air. High pressure will bring a change in airmass today. A relief for most from the high dewpoints.
634 AM CDT Mon Jul 1 2024 (Today and tonight) Persistence is the name of the game today as another hot and dry day is expected across the region as the upper-level ridge slowly drifts towards the ArkLaTex region. Weather won't be too different overnight either with low temperatures ranging from the low to mid 70s on the Caprock and mid to upper 70s east of the Caprock escarpment although southerly breezes will remain around 10-15 mph.
Temperatures remain in the lower 80s and with the slightly less cloud cover, lows by morning should be in the middle to upper 70s for most locations. Models are showing highs Tuesday a bit warmer with highs in the upper 90s to 103 degree range.
Hernandez Previous Discussion: /Trough Tuesday/ Not much change to our sensible weather is expected today compared to this past weekend as we remain under a strong ridge overhead.
1034 AM EDT Mon Jul 1 2024 High pressure builds in from the Great Lakes today, bringing less humid air. High pressure is building into the forecast area from the north providing a significant airmass change. A relief for most from the high dewpoints.
Upper level ridging currently over the region will get pushed east today as a trough approaches from the west. At the surface, the CWA is currently between high pressure to the east and low pressure to the west. The low, and its associated frontal boundary, will be over the western part of the state to start today. The area will then see mainly dry conditions overnight through the day Tuesday as weak high pressure settles in behind the exiting front. High temperatures today will range from the upper 60s along the Sisseton Hills region, to the lower 80s west of the Missouri River. Highs on Tuesday will be in the upper 70s to the lower 80s. Tuesday evening, we are still in an upper level trough pattern and will continue in this pattern through the end of the period.
409 AM MDT Mon Jul 1 2024 Expect unsettled weather to continue through midweek this week as broad upper level troughing remains in place, bringing daily chances for afternoon showers and thunderstorms across the area. A significant warm up is possible later this week as upper level ridging builds across the Western United States.
1145 AM MDT Mon Jul 1 2024 - A cold front today brings cooler temperatures and rain chances, mainly across the northern half of Wyoming. A cold front moves through the area today. As a result, it will be noticeably cooler, especially compared to the highs yesterday that were in the 90s for many locations, with a few 100s noted. The best chances continue across the northern part of the state through the day as broad trough influences the area. Precipitation continues across the north tonight as the broad trough remains in place.
229 PM EDT Mon Jul 1 2024 - Cooler temperatures and dry conditions persist through Tuesday.
1232 PM CDT Mon Jul 1 2024 (Today and tonight) Persistence is the name of the game today as another hot and dry day is expected across the region as the upper-level ridge slowly drifts towards the ArkLaTex region. Weather won't be too different overnight either with low temperatures ranging from the low to mid 70s on the Caprock and mid to upper 70s east of the Caprock escarpment although southerly breezes will remain around 10-15 mph.
Dry and warmer tomorrow as ridging strengthens across the region. Ridging strengthens across the region tomorrow, allowing for warmer but near normal temperatures. Southerly flow returns in the low levels tomorrow, meaning dewpoints will be slightly higher.
1128 AM CDT Mon Jul 1 2024 Weather conditions are much more pleasant across the Mid-South today as drier air and cooler temperatures have settled over the region behind yesterday's cold front. Current temperatures range from the upper 70s to the mid 80s with dewpoints in the 60s, resulting in heat indices approximately 20-25 degrees cooler than at this time yesterday. There are some mid-level clouds streaming southeast across the Ozarks, but they continue to erode as they approach I-40 and run into the subsidence provided by the subtropical ridge.
Mid morning surface analysis showed a dry cold front along our Highway 82 corridor. This front has brought in slightly drier air knocking dew points in the lower 70s. Surface dew points in the 60s are expected across our northern zones this afternoon as the dry cold front continues to sag a little farther south into our CWA. /22/ Today and Tonight: The upper-level ridge centered over East Texas this morning is analyzed around 596 dam at 500mb - or near max values for this time of year. Subsidence beneath this ridge will be the main driver again for dangerous heat across the Gulf Coast region today, but at least some drier air is moving into parts of our forecast area behind a weak cold front.
129 PM EDT Mon Jul 1 2024 (Today through Tuesday) Monday will be warm and unsettled as a mid-level trough lingers over the region. At the surface, South Florida remains on the periphery of Atlantic high pressure with the ridge axis sitting around Lake Okeechobee. Mid-level high pressure begins to slide east from the southern plains towards the southeastern United States on Tuesday. The high will not build all the way into southern Florida, therefore allowing the unsettled, diurnally-driven storm pattern to continue for another day with a southeasterly wind flow.
355 PM EDT Mon Jul 1 2024 Showers and thunderstorms may accompany a cold front moving south across the Carolinas today.
Broad troffing exists over the region and with diurnal heating and modest instability, there are isolated showers developing over our west. Furthermore, snow levels look to fall to near 10,500 feet, which is enough for snow at the highest elevations of the Beartooth-Absarokas. and possibly the high reaches of Beartooth Pass. Temps will be a bit cooler than early July normals.
(Tonight through Tuesday night) An upper-level ridge over Northeast Texas will remain the dominate feature as it shift further east through the period. Broad subsidence associated with this ridge and relatively dry mid levels should keep rain chances near zero, once this current batch of convection clears out later this afternoon.
1106 AM EDT Mon Jul 1 2024 High pressure will provide dry and comfortable weather for the first half of the week before an unsettled pattern takes hold to close out the week. Slow height rises aloft and building high pressure will provide dry and comfortable conditions with lots of sunshine.
Again, dry conditions expected under upper ridging. (Tuesday night through next Monday) Upper level ridging will remain in control over west central Texas through the 4th of July holiday.
(This evening through Tuesday) Heat Advisory, marginal risk of severe thunderstorms, and elevated The mid-level ridge that was centered over northeast Texas begins to shift eastward over the ArkLaTex region this evening as a broad mid-level trough impinges on the plains. Breezy S/SW-ly winds with gusts to 35 mph along with very hot conditions are expected tomorrow as the lee-side trough deepens. In addition, strong to severe thunderstorms are expected to develop ahead of an approaching cold front by late afternoon and into the evening across northwest and northern Oklahoma.
113 PM CDT Mon Jul 1 2024 Mid morning surface analysis showed a dry cold front along our Highway 82 corridor. This front has brought in slightly drier air knocking dew points in the lower 70s. Surface dew points in the 60s are expected across our northern zones this afternoon as the dry cold front continues to sag a little farther south into our CWA. /22/ Today and Tonight: The upper-level ridge centered over East Texas this morning is analyzed around 596 dam at 500mb - or near max values for this time of year. Subsidence beneath this ridge will be the main driver again for dangerous heat across the Gulf Coast region today, but at least some drier air is moving into parts of our forecast area behind a weak cold front.
156 PM EDT Mon Jul 1 2024 High pressure will shift off to the east tonight through Tuesday.
The mid-level high and associated 500 mb ridge will slowly migrate eastward today and tomorrow but will maintain a nose into Texas, keeping our region under an easterly flow aloft. This will maintain overall subsidence and will help to moderate temperatures since we won't be baking underneath the center of the high pressure system. As the trough associated with Post Tropical Storm Chris moves westward over Mexico, skies over South Texas are expected to clear, with only Saharan dust resulting in lingering haze this afternoon across the region. This will result in a minor to moderate risk of heat-related impacts today and likely continuing tomorrow, despite the warmer temperatures.
Broad upper level troughing across the Northern Rockies will support a generally cooler than average period through the 4th of July.
1243 PM EDT Mon Jul 1 2024 Cooler and drier air works into the region today behind a departing cold front.
- Continued cooler temperatures and increased precipitation chances through mid-week across northern Wyoming. As the cold front is draped across Wyoming, rain showers and thunderstorms have been observed, as well as wind gusts along and behind the front of 30 to 40 mph, even higher in wind prone areas and from thunderstorm outflow.
158 PM EDT Mon Jul 1 2024 Cooler and dry to start the work week, then temperatures warm for Tuesday.
At the surface, the western periphery of the subtropical ridge extends into the Florida Keys. For the remainder of the forecast package, an upper level ridge is expected to be the main driver of the pattern. However, we will be teetering on the edge of Heat Advisories with highs in the lower 90s and dew points of 77 to 78 degrees.
225 PM EDT Mon Jul 1 2024 High pressure builds in today with dry conditions expected for the first half of the week.
Convection and cloud debris will keep highs tomorrow in the lower 90s with heat indices in the low 100s.
Again, dry conditions expected under upper ridging.
1226 PM CDT Mon Jul 1 2024 Weather conditions are much more pleasant across the Mid-South today as drier air and cooler temperatures have settled over the region behind yesterday's cold front. Current temperatures range from the upper 70s to the mid 80s with dewpoints in the 60s, resulting in heat indices approximately 20-25 degrees cooler than at this time yesterday. There are some mid-level clouds streaming southeast across the Ozarks, but they continue to erode as they approach I-40 and run into the subsidence provided by the subtropical ridge.
This likely will erode aways as the cloud field clears for better insolation and allowing the low and mid level lapse rates above 7. There is very small area of diffluence aloft that can aid in the storm development, but the lower levels will need to the heavy lifting (i. A few storms may be Severe Storm worthy in the late afternoon if the CAPE values are high, better inflow, shear, and cooler air in the midlevels (breaking the subsidence inversion).
255 PM EDT Mon Jul 1 2024 High pressure will provide dry and comfortable weather for the first half of the week before an unsettled pattern, with periods of showers and storms, takes hold to close out the week. ------------------------------------------------------------------- High pressure will maintain comfortable - i.
- Severe storms possible late Tue afternoon and evening along a weak cold front. Water vapor imagery currently shows upper troughing moving into the Northern Rockies and extending down into the Great Basin. Meanwhile, upper ridging is centered across the Arklatex region. At the surface, warm front continues to lift north and is currently situated from NW KS into southwest MO. Meanwhile, low pressure continues to strengthen over northeast CO/far western Nebraska. Upper trough is expected to continue tracking east and will be moving out across the Central/Northern Plains on Tue. This will allow a cold front to sag south which will likely be aided by outflow from overnight convection.
356 PM EDT Mon Jul 1 2024 Much drier and cooler high pressure will then extend into the southeast today through Tuesday. Post-frontal dry air continues to spill south into central NC this afternoon as dew points are currently hovering in the lower to mid 50s (N) to lower 60s (S). Light northerly flow will result in temps ranging in the low to mid 80s for much of the area. Tuesday night will be dry and clear with lows ranging in from the low to mid 60s.
142 PM PDT Mon Jul 1 2024 * High pressure will bring a significant warmup this week with a prolonged heatwave setting up over the 4th of July weekend.
207 PM EDT Mon Jul 1 2024 High pressure builds in today with dry conditions expected for the first half of the week.
The higher heat indices will be in the lower elevation areas of eastern OK and the lower values in the higher terrain of northwest AR. Tonight will be quiet with lows ranging from the low 70s to near 80 F. The big picture will feature an elongated ridge from central Texas towards North Carolina. Meanwhile, a trough will dig across the northern Plains. Specific humidity in the lower atmosphere will continue to run near the 99th percentile for this time of year.
Sfc analysis shows Atlc ridge axis extends westward across central FL producing a light south flow this morning.
Expect unsettled weather to continue through midweek this week as broad upper level troughing remains in place, bringing daily chances for afternoon showers and thunderstorms across the area. A significant warm up is possible later this week as upper level ridging builds across the Western United States. Broad troughing in place across the Northern Rockies will result in late morning through early evening scattered showers and thunderstorms today.
A sprawling and strong upper-level ridge has settled across the Eastern Half of the CONUS, amplifying the flow across the NE and leading to a weak upper-level low feature off the FL East Coast. At the surface, a the subtropical ridge has retreated slightly farther to the east, with very light easterly flow (much like regime 6) in place. As the upper-level ridge flattens out this weekend and the flow becomes more zonal once more, the subtropical ridge looks to build back to the west, bringing a WSW fkow back to the region.
223 PM EDT Mon Jul 1 2024 High pressure will build over the region on Tuesday.
The mid-level ridge responsible for our current bout of heat continues its transit from west to east through the southern tier of states.
Tuesday, the trough will progress eastward and out of the area.
- Cooler and drier conditions return Tuesday with chances for terrain based showers and thunderstorms along the Continental Divide and our southern mountains.

900 PM EDT Mon Jul 1 2024 A strong area of high pressure will pass north of the area through Tuesday before drifting offshore by Tuesday night.
/NEW/ /Tonight through Tuesday Night/ Mid level ridging will continue to dominate the weather pattern through the middle part of the week with temperatures above 100 degrees expected and little chance for rainfall. Nearly cloud free skies prevail beneath the ridge this evening, although an axis of higher moisture content across East Texas has lead to a few scattered showers and storms. Clear skies are expected tonight with temperatures again only falling into the lower 80s. The center of the ridge axis will begin an eastward shift later tonight and mid level heights will actually fall a bit through Tuesday and the middle of the week.
918 PM CDT Mon Jul 1 2024 Skies are mostly clear across the Mid-South this evening with temperatures in the lower 70s to around 80 degrees.
(The rest of tonight) As of mid evening the dome of high pressure a loft remained the main feature over eastern Oklahoma and northwest Arkansas. The big picture will feature an elongated ridge from central Texas towards North Carolina. Meanwhile, a trough will dig across the northern Plains. Specific humidity in the lower atmosphere will continue to run near the 99th percentile for this time of year.
645 PM EDT Mon Jul 1 2024 Much drier and cooler high pressure will then extend into the southeast today through Tuesday. Post-frontal dry air continues to spill south into central NC this afternoon as dew points are currently hovering in the lower to mid 50s (N) to lower 60s (S). Light northerly flow will result in temps ranging in the low to mid 80s for much of the area. Tuesday night will be dry and clear with lows ranging in from the low to mid 60s.
647 PM EDT Mon Jul 1 2024 - Cooler temperatures and dry conditions persist through Tuesday.
A cold front stalled over northern Utah has kept conditions mild and cloud with hot, dry and windy conditions further south.
616 PM CDT Mon Jul 1 2024 (Tonight through Tuesday night) An upper-level ridge over Northeast Texas will remain the dominate feature as it shift further east through the period. Broad subsidence associated with this ridge and relatively dry mid levels should keep rain chances near zero, once this current batch of convection clears out later this afternoon.
Showers and storms continue along a line from Rosco to Mobridge southwest through Murdo/Wind River to the Kakota area.
Showers and thunderstorms have pushed into eastern Idaho this evening following the passage of an upper trough axis.
1053 PM EDT Mon Jul 1 2024 High pressure will shift off to the east tonight through Tuesday.
824 PM EDT Mon Jul 1 2024 High pressure will shift off to the east tonight through Tuesday.
1018 PM EDT Mon Jul 1 2024 Upper ridge across the Mississippi Valley continues to place our region within an area of subsidence with a clear sky and no precipitation across the region. This general pattern continues tomorrow with increasing temperatures as ridging continues to shift eastward across the Tennessee Valley. Dry and warmer tomorrow as ridging strengthens across the region. Ridging strengthens across the region tomorrow, allowing for warmer but near normal temperatures. Southerly flow returns in the low levels tomorrow, meaning dewpoints will be slightly higher.
Temperatures this afternoon will reach the low to mid 70s. Tonight, upper-level troughing as well as a strengthening jet streak will reach the northern plains where WAA is strongest. The system will be slow to exit Tuesday morning to our west as a cold front becomes occluded over northwestern MN. Tuesday's highs temperatures will reach the lower 80s and then upper 70s across western WI where cloud cover will be more prevalent.
Look for highs in the low 90s with HI values nearing triple digits tomorrow afternoon.
634 PM CDT Mon Jul 1 2024 (This evening through Tuesday) Heat Advisory, marginal risk of severe thunderstorms, and elevated The mid-level ridge that was centered over northeast Texas begins to shift eastward over the ArkLaTex region this evening as a broad mid-level trough impinges on the plains. Breezy S/SW-ly winds with gusts to 35 mph along with very hot conditions are expected tomorrow as the lee-side trough deepens. In addition, strong to severe thunderstorms are expected to develop ahead of an approaching cold front by late afternoon and into the evening across northwest and northern Oklahoma.
705 PM EDT Mon Jul 1 2024 High pressure will build over the region on Tuesday.
Not helped by the warmer temperatures aloft. Strong mid level ridge over the deep South will build heights over FL increasing subsidence/drying aloft and this will gradually reduce coverage of diurnal convection. Max temps in the low to mid 90s is at or slightly above normal but the high dewpoints/humidity will produce maximum heat index readings of 102-107. Our weather will continue to be dominated by the strong upper high, characterized by H5 heights exceeding the 95th percentile of climatology.
1030 PM EDT Mon Jul 1 2024 High pressure will build over the region on Tuesday.
