723 AM EDT Mon Jun 24 2024 (Today through Tuesday) The week will start off with continued unsettled weather across South Florida as mid-level troughing dives down across the eastern US, pushing out any influence of mid-level ridging over the area. This, along with extra lift from the mid-level troughing, will result in another day of scattered to numerous showers and thunderstorms, primarily initiating along sea breeze boundaries. Storm motion will remain slow with weak winds in the low to mid levels, which will lead to localized flooding concerns for poor drainage areas or locations that see multiple rounds of storms. The overall synoptic and mesoscale setup will not change much on Tuesday aside from the mid-level troughing over the area slightly weakening.
603 AM CDT Mon Jun 24 2024 (Today through Tuesday Night) Ridging over the Desert Southwest/Texas should continue to dominate the weather pattern early this week. Tuesday also appears to be borderline as well, though slightly warmer.
An upper level ridge will rebuild into the region today and Tuesday for warmer and drier conditions.
657 AM EDT Mon Jun 24 2024 Showers and thunderstorms tapering off as a cold front crosses this morning.
Upper level ridging influences will strengthen and become main weather player tonight through Tuesday.
809 AM EDT Mon Jun 24 2024 A strong U/L ridge over the southern plains will extend over the Florida peninsula through Tuesday, but will slowly retrograde toward the desert southwest.
607 AM CDT Mon Jun 24 2024 (Today and tonight) Upper level high pressure centered near El Paso today and tonight with a significant extension of the ridge eastward across Texas will keep the weather fair but hot across the forecast area.
Additional thunderstorm chances (15-30%) on Tuesday as a cold front moves through the area.
With dewpoints mixing into the low to mid-60s, heat indices are forecast to be around the mid to late-90s, later in the day.
Issued 431 AM CDT Mon Jun 24 2024 Today through Tuesday night: High pressure will shift ewd today with sly winds developing this afternoon.
Temperatures will climb to the upper 90s and lower 100s this afternoon nearly everywhere minus the higher terrain.
Temperatures will heat up a few degrees as high pressure builds overhead. High pressure will strengthen over the desert southwest with a new high center consolidating nearly overhead over the next 36 hours.
79 Previous Discussion: /Overnight through Monday Night/ The large scale weather pattern will remain unchanged to start the work week with a mid-level ridge anchored from the Desert Southwest to the Lower Mississippi Valley. /Issued 308 AM CDT Mon Jun 24 2024/ /Tuesday Onward/ Upper ridging will shift westward by midweek, with amplifying northerly flow present through the Central Plains.
A strong U/L ridge over the southern plains will extend over the Florida peninsula through Tuesday, but will slowly retrograde toward the desert southwest.
Otherwise, skies are expected to be mostly sunny today and Tuesday, allowing for warmer temperatures to work back into the region. With the high moisture content already present, heat indices could climb into the 105-110 range this afternoon, with slightly warmer temperatures possible Tuesday afternoon.
Upper level ridging will continue to spread eastward along the Gulf Coast today. Tonight, if we do get a little rain, some shallow ground fog may be possible, but given the low coverage didn't add to the forecast now. As it fades to a remnant trough on Tuesday, it will be just enough to interact with the diurnal cycle to help generate a few more isolated to scattered showers/storms on Tuesday as well.
621 AM CDT Mon Jun 24 2024 (Today through Tuesday Night) The upper level ridge is centered over Texas and affecting the central and western parts of the country. An upper trough will move through the northeast U. The southern ridge will expand into the Rockies Tuesday.
From synopsis, high pressure over the western Atlantic and low pressure over the Bay of Campeche will maintain gentle east to southeast breezes through tonight.
Temperatures will be around 10 to 15 degrees above average Today with widespread triple digit highs across the lower elevations.
603 AM CDT Mon Jun 24 2024 (Today and tonight) The 500mb subtropical ridge across the southwest and south central United States will continue to provide subsidence across west central Texas today through tonight.
620 AM CDT Mon Jun 24 2024 (Today through Tuesday) The upper level ridge centered over and northwest of the area will continue to produce for most locations a dry forecast through the short term. Beneath the ridge is a pool of elevated moisture across the Coastal Plains and there is a 10-20% chance of stray to isolated tropical showers and thunderstorms in forecast this afternoon across this area.
- Chances for precipitation and cooler temperatures look to arrive for the second half of the week. After doing some digging in the climate data, the high of 104 was actually one of the top 5 highest temperatures recorded in the month of June for Greybull. Unfortunately the heat will remain for one more day before we see slightly cooler temperatures for Tuesday.
545 AM EDT Mon Jun 24 2024 Dry and cooler weather is expected today under building high pressure.
646 AM EDT Mon Jun 24 2024 Dry and cooler weather is expected today under building high pressure.

1226 PM CDT Mon Jun 24 2024 A weak cold front remains located from Central Arkansas southeastward through the Mississippi Delta into Central Alabama.
The high pressure will again dominate the forecast over the next two days and with the large amount of dry air seen through the upper levels being the main driving factor.
353 PM EDT Mon Jun 24 2024 Dry and cooler weather is expected tonight under high pressure.
/Issued 1223 PM CDT Mon Jun 24 2024/ /Through Tomorrow Afternoon/ The summer heat is upon North and Central Texas as an upper-level ridge has settled atop our region. This ridge, which spans across much of the Southern Plains, will help keep precipitation at bay. Tomorrow, temperatures will be a few degrees warmer compared to today, thus, more widespread 105+ heat index values are expected.
Upper ridge continues with above normal temperatures and dry conditions.
Upper ridging will continue to build today, with light winds aside from some higher gusts over the Reeves County plains and Lower Trans Pecos into the eastern Stockton Plateau. While warmer than yesterday, Heat Advisory criteria is not expected to be reached today. Tuesday continues the warming trend as ridging continues to amplify. Tuesday night will once again feature a warmer than average night, with lows again mostly falling into the 70s or above.
With strong ridging occurring aloft, still not enough confidence to include mentionable PoPs at this time, but did include silent PoPs (10%) for portions of northwest AR and into parts of far southeast OK through about 7 PM. Some CAMS suggest potential for a few showers/storms this afternoon in the higher terrain of far E OK and NW AR, but will not include any mention as coverage should remain very low.
(Tonight) Upper level ridging over the Plains looks to build east over the region tonight.
1240 PM CDT Mon Jun 24 2024 (Rest of today through Tuesday) Sunny, cooler and less humid day across Middle Tennessee today thanks to a cold front that moved through the region last night, with current temperatures in the 80s and dewpoints in the upper 50s to mid 60s. Highs will only reach the mid 80s to low 90s today thanks to this cooler and drier airmass, with lows tonight quite nice for late June in the upper 50s on the Plateau and 60s elsewhere. Unfortunately, this cooldown will be shortlived as upper ridging aloft builds back in. Thankfully, the lower dewpoints will help to make it feel not quite so hot tomorrow.
302 PM EDT Mon Jun 24 2024 High pressure will build overhead tonight bringing a clear and cool summer night.
The synoptic pattern remains unchanged with an area of high pressure continuing to sit overtop the state. With the 500mb temperatures continuing to reach above the 90th percentile per NAEFS/GFS, not expecting to see this high pressure weaken in the short-term period.
/16 (Now through Tuesday) An upper level ridge currently stretches southeast over the northern Gulf of Mexico, north-central Gulf coast, with a mean upper level trough along the East Coast. A weak cold front continues to move south over the forecast area, with isolated convection along and south. Tonight through Tuesday, guidance is advertising moisture levels dropping as northerly flow on the west side of the East Coast upper trough re-asserts itself, with precipitable h20 levels of 1. Guidance is also advertising the upper ridge building a bit.
Ridging will begin to build back into the Northern Rockies on Tuesday, resulting in warm and dry conditions.
Current surface analysis shows the low over eastern SD, with a weak cold front stretching into southwestern SD.
257 PM EDT Mon Jun 24 2024 A brief respite in the heat and humidity today, before warmer and more humid air quickly builds back into the region on Tuesday.
Not much change in the overall weather pattern through Tuesday with an upper level high pressure maintaining an influence on S TX weather. Models indicate the center of the high pressure will shift slightly west Tuesday with a weak inverted trough moving west around the southern periphery of the high, but the high pressure will maintain a subsident airmass across the area and keep rain chances low (5-20%). Abundant moisture will remain in the lower levels with PWATs remaining around 2 inches through Tuesday. The current Coastal Flood Advisory ends at 7 pm this evening and am not planning on extending it given the low chance of minor coastal flooding at the next time of high tide Tuesday morning.
1230 PM CDT Mon Jun 24 2024 (Today through Tuesday) The upper level ridge centered over and northwest of the area will continue to produce for most locations a dry forecast through the short term. Beneath the ridge is a pool of elevated moisture across the Coastal Plains and there is a 10-20% chance of stray to isolated tropical showers and thunderstorms in forecast this afternoon across this area.
The higher PW values and more robust CAPE are once again located in Yavapai County and southern Coconino County.
- Widely scattered 10-25% areal coverage thunderstorms possible through the Highway K-96 corridor of west central Kansas between about 9 pm and 3 am. Temperatures have been a little slow to reach the high 90s and 100 degree mark in the eastern counties, however with still a little time in the day for temps to rise, and the mid 60s dew points in the area, the heat advised counties seem well justified.
1236 PM CDT Mon Jun 24 2024 (Today through Tuesday Night) Ridging over the Desert Southwest/Texas should continue to dominate the weather pattern early this week. Tuesday also appears to be borderline as well, though slightly warmer.
Storm motion will remain slow with weak winds in the low to mid levels, which could lead to localized flooding concerns for poor drainage areas or locations that see multiple rounds of storms.
There is a slight chance of showers and thunderstorms for the mountains into the high desert for this afternoon and early evening with lesser chances for Tuesday afternoon. WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO Temperatures at 9 AM today were running 3 to 7 degrees cooler than yesterday for the valleys, mountains, and High Desert. Temperatures along the immediate coast and in the low deserts at 9 AM were a mix of about the same as yesterday to a degree or two warmer. High temperatures today are expected to be 2 to 5 degrees cooler than yesterday west of the mountains with no significant change in the deserts.
140 PM EDT Mon Jun 24 2024 Dry and cooler weather is expected today under building high pressure.
An area of high pressure over west TX this morning will expand over the region and will be influenced under high pressure and subsidence for the foreseeable future. Highs today will be in the low to mid 90s with heat indices between 105-109 degrees. Afternoon highs will range in the low to upper 90s across the region with heat indices climbing into 105-109 range with some locales in the southern Coastal Bend/northern Brush Country possibly exceeding 110 degrees briefly.
(This evening through Tuesday) An upper level ridge centered over Chihuahua is expected to persist through the short term period, gradually edging northward into Tuesday. The influence of this ridge should continue the upward trend in temperatures, with Tuesday's highs exceeding 100 degrees F off the Caprock and across the southern South Plains. Westerly flow aloft should turn NNW by Tuesday evening as the center of the upper-level ridge moves over Las Cruces.
with upper level ridging firmly in control over the southwestern U. Rinse and repeat for Tuesday afternoon, with temperatures ticking a couple of degrees warmer than today. Highs will be in the 98-103 range, with the highest readings across the Concho Valley and Big Country.
A mid and upper level ridge is currently centered from roughly southern Arizona into central/southern Texas. The ridge is expected to build over the southwestern states through Tuesday.
Westerly flow gives way to a ridge of high pressure on Tuesday. While dry (low relative humidity) conditions continue, winds will relax under the ridge.
(Tonight through Tuesday night) The upper level ridge centered over and northwest of the area will continue to produce for most locations a dry forecast through the short term. Beneath the ridge is a pool of elevated moisture across the Coastal Plains and there is a 10-20% chance of stray to isolated tropical showers and thunderstorms in forecast this afternoon across this area.
1158 AM CDT Mon Jun 24 2024 (Today through Tuesday Night) The upper level ridge is centered over Texas and affecting the central and western parts of the country. An upper trough will move through the northeast U. The southern ridge will expand into the Rockies Tuesday.

/NEW/ /Through Tomorrow Afternoon/ The summer heat is upon North and Central Texas as an upper-level ridge has settled atop our region. This ridge, which spans across much of the Southern Plains, will help keep precipitation at bay. Tomorrow, temperatures will be a few degrees warmer compared to today, thus, more widespread 105+ heat index values are expected. /Issued 308 AM CDT Mon Jun 24 2024/ /Tuesday Onward/ Upper ridging will shift westward by midweek, with amplifying northerly flow present through the Central Plains.
Pattern Synopsis/Pattern Forecast: Mid/upper level ridge in the process of building east across the area early this afternoon as its surface reflection pushes off into the northern Ohio Valley. Surge of pre-system warm, moist advection and eventual passage of cold front set to bring a round of showers and thunderstorms into the region later tonight. Actual cold front set to cut west to east across our area during the morning and early afternoon, with that timing at least theoretically supporting the potential for additional destabilization. PATTERN SYNOPSIS/FORECAST: Longwave troughing will continue chances of active weather before a ridge of high pressure builds overhead promoting quieter weather by mid-week. Low pressure tracks along the northern U.
Hot and muggy today, with afternoon highs in the low 90s, except mid 90s possible across the north where less cloud cover is expected.
Although showers are widespread any thunderstorms have struggled which could be due to the warmer temperatures aloft as revealed in this morning's 12z sounding. As the trough that has been the main driver of our active weather retreats east and away from Florida over the next day, our winds will in result shift to the west southwest. Thereafter, towards the end of the week the ridge will move northward and we will return to our more typical summer pattern with east to southeast flow and near normal PoPs of around 30%. From synopsis,high pressure over the western Atlantic and low pressure over the Bay of Campeche will maintain gentle east to southeast breezes through tonight.
(Rest of today through Tuesday) Sunny, cooler and less humid day across Middle Tennessee today thanks to a cold front that moved through the region last night, with current temperatures in the 80s and dewpoints in the upper 50s to mid 60s. Highs will only reach the mid 80s to low 90s today thanks to this cooler and drier airmass, with lows tonight quite nice for late June in the upper 50s on the Plateau and 60s elsewhere. Unfortunately, this cooldown will be shortlived as upper ridging aloft builds back in. Thankfully, the lower dewpoints will help to make it feel not quite so hot tomorrow.
Discussion: An upper and surface ridging will build back into the Tennessee valley and southern Appalachians. These values are also near the lowest 10 percentile.
Near normal high temperatures are expected on Tuesday as Deep South Texas remains under the influence of mid/upper level ridging centered over West Texas and New Mexico, with highs mostly in the 90s.
This has pushed temperatures in the central and western Midlands up several degrees in the past hour with readings in the low to mid 90s already. High temperatures this afternoon will be in the upper 90s with low tonight falling into the low to mid 70s. Upper level ridge building again as long wave trough axis off the coast. The CAM models are suggesting scattered thunderstorms will focus near the frontal boundary/trough in the southeast Midlands and coastal Plain. Overnight lows continue to range in the low to mid 70s.
336 PM EDT Mon Jun 24 2024 A cold front moving into the area will bring thunderstorms to the area this evening.
A ridge axis extending from the western North Atlantic has begun to sag southward across the Florida Peninsula this evening. Some portions of the Upper Keys received almost 2" of rainfall within a short period of time due to the slow movement of these showers that developed along a cloud line, while up to 1" of rainfall in portions of the Lower Keys from another cloud line.
At the surface, a ridge of high pressure will remain centered across the southern Appalachians and provide light/variable winds, which will work in conjunction with clear skies to allow temperatures to fall into the lower 60s (E) and m-u 60s (W) by sunrise.
Temperatures will be around 10- degrees above average again on Monday with widespread triple digit highs across the lower elevations.
953 PM EDT Mon Jun 24 2024 A brief respite in the heat and humidity today, before warmer and more humid air quickly builds back into the region on Tuesday.

Hotter temperatures will return Tuesday as an upper level ridge builds overhead, accompanied by southwest flow aloft.
923 PM EDT Mon Jun 24 2024 High pressure will build overhead tonight bringing a clear and cool summer night.
High pressure aloft continues to build over the region, maintaining warmer and dry conditions through Tuesday.
847 PM CDT Mon Jun 24 2024 Forecast remains on track with cool overnight lows thanks to the cooler and drier airmass we saw today. Those cooler temps in the early morning hours wont last long though as daytime highs climb right back into the 90s Tuesday.
640 PM CDT Mon Jun 24 2024 (Tonight) Upper level ridging over the Plains looks to build east over the region tonight.
627 PM CDT Mon Jun 24 2024 (This evening through Tuesday) An upper level ridge centered over Chihuahua is expected to persist through the short term period, gradually edging northward into Tuesday. The influence of this ridge should continue the upward trend in temperatures, with Tuesday's highs exceeding 100 degrees F off the Caprock and across the southern South Plains. Westerly flow aloft should turn NNW by Tuesday evening as the center of the upper-level ridge moves over Las Cruces.
While the frontal passage didn't bring much relief in the way of cooler temperatures, it did at least bringing a considerably drier airmass (reflected by dewpoints in the 50s). The high pressure will again dominate the forecast over the next two days and with the large amount of dry air seen through the upper levels being the main driving factor.
730 PM EDT Mon Jun 24 2024 A brief respite in the heat and humidity today, before warmer and more humid air quickly builds back into the region on Tuesday.
