Hot temperatures will continue through the end of the week, with daily chances for showers/thunderstorms across the higher terrain through the weekend.
545 AM EDT Thu Jun 6 2024 Showers and isolated thunderstorms will end this morning as a cold front exits the region. A secondary trough will result in a few more scattered showers and possible thunderstorms this afternoon and evening. An unsettled weather pattern is then expected through the weekend under a persistent upper trough. Partial clearing and dry weather is then expected into early afternoon as surface ridging briefly builds in. KEY MESSAGES: - Persistent upper trough maintains an unsettled pattern - Cooler temperatures expected ------------------------------------------------------------------- Isolated evening showers and thunderstorms should end tonight as the reinforcing trough completes its passage.
545 AM CDT Thu Jun 6 2024 - Scattered showers possible this morning, followed by cooler afternoon temps.
601 AM CDT Thu Jun 6 2024 (Today) A weak cold front will drift south into the area this afternoon and evening.

KEY MESSAGES: - Persistent upper trough maintains an unsettled pattern - Cooler temperatures expected ------------------------------------------------------------------- Isolated evening showers and thunderstorms should end tonight as the reinforcing trough completes its passage.
534 AM CDT Thu Jun 6 2024 Today and tonight: Low pressure will begin to shift east as a cold front pushes south across the area today. Storms will gradually shift southeastward as the cold front continues to sag.
636 AM EDT Thu Jun 6 2024 A weak cold front moving through the region today will result in the potential for a few showers. High pressure and a drier, cooler airmass will settle into the Ohio Valley tonight into Friday. Shower activity has just about ended across our area early this morning as the initial cold front moves east of our area. Any lingering shower activity across our southeast should taper off heading into this evening as the cold front moves through.
(Today) Early morning analysis shows a short wave at the tail end of a longwave trough becoming partially closed off across the region. However, showers may expand in coverage as a cold front associated with the mid/upr short wave crosses the area along with the advent of daytime heating. Although, the low-lvl Td gradient will lag behind the front so that we won't begin to experience the true dry air advection until Friday.
As the ridge flattens Friday into the weekend, the warming trend will curb and some moisture will move into the area, increasing the threat of convection.
955 AM EDT Thu Jun 6 2024 Humidity and storm coverage will increase today before a weak cold front moves through early Friday.
639 AM CDT Thu Jun 6 2024 (Today through Friday Night) Fntl bndry was situated acrs eastern AR early this mrng, along with a corresponding upper trof. The aforementioned upr trof/fnt wl cont to work to the east today. This wl allow aftn highs to top out in the mid 80s to the lower 90s.
556 AM CDT Thu Jun 6 2024 (Today and tonight) The upper pattern isn't much to write about this morning as a broad dome of high pressure jostles east toward New Mexico resulting in rising heights and anemic northwest flow over much of our area. The lower levels meanwhile turn more interesting thanks to a fetch of moist southerlies aiding in PWATs around 130 percent of normal and a weak cold front forecast to settle near I40 later this afternoon. One factor that may help sustain convection after sunset is a modest theta-e ridge and LLJ expanding over the South Plains in response to low- level winds backing SE and moistening.
602 AM CDT Thu Jun 6 2024 - Breezy northwest winds with gusts up into the lower 40s possible. Strongest gusts are expected along the Buffalo Ridge given their elevated elevation.
430 AM MDT Thu Jun 6 2024 Updated Aviation Discussion Mainly sunny, warm and dry conditions with relatively light winds are expected today as upper level high pressure strengthens south and west of the area.
344 AM MDT Thu Jun 6 2024 Mainly sunny, warm and dry conditions with relatively light winds are expected today as upper level high pressure strengthens south and west of the area.
1140 AM CDT Thu Jun 6 2024 (Today through Friday Night) Fntl bndry was situated acrs eastern AR early this mrng, along with a corresponding upper trof. The aforementioned upr trof/fnt wl cont to work to the east today. This wl allow aftn highs to top out in the mid 80s to the lower 90s.
This morning's thunderstorms have exited the region, and northerly winds are reinforcing the cooler and drier air compared to yesterday.
1225 PM CDT Thu Jun 6 2024 (Today and tonight) The upper pattern isn't much to write about this morning as a broad dome of high pressure jostles east toward New Mexico resulting in rising heights and anemic northwest flow over much of our area. The lower levels meanwhile turn more interesting thanks to a fetch of moist southerlies aiding in PWATs around 130 percent of normal and a weak cold front forecast to settle near I40 later this afternoon. One factor that may help sustain convection after sunset is a modest theta-e ridge and LLJ expanding over the South Plains in response to low- level winds backing SE and moistening.
221 PM EDT Thu Jun 6 2024 Another cold frontal passage by late afternoon or evening promotes isolated showers and thunderstorms through midnight.
(Rest of today through Friday night) Issued at 1115044 AM CDT Thu Jun 6 2024 After a very warm and humid Thursday, passage of a late day cold front will bring cooler and less humid conditions.
Dew points have dipped into the lower to middle 60s in north central and northwest TN. A cold front in southern IL and MO will arrive later tonight, shifting the wind to the northwest. Morning lows will be in the lower to middle 60s.
2) Cooler and drier weather moves in overnight. This will allow temperatures to drop several degrees cooler than last nights lows.
314 PM EDT Thu Jun 6 2024 * Less humid air arrives tonight in the wake of a cold front.
(This afternoon through Friday night) The short term synoptic pattern is generally dictated by the dominant upper ridge overhead, set to slowly meander eastward through Texas tomorrow. The main headlines under this pattern will be the continued heat, with high temperatures exceeding the triple digits both today and tomorrow afternoon region-wide except the higher elevations and Heat Advisories are in effect today for most zones along and west of the Pecos River. The low-level thermal ridge remains at a similar location/intensity for tomorrow, albeit maybe a degree C cooler, and as such, more Heat Advisories are likely for tomorrow as well. Aside from the heat, the other focus in the short term is on largely diurnally and orographically driven convection across the higher terrain today and tomorrow.
Mainly sunny, warm and dry conditions with relatively light winds are expected today as upper level high pressure strengthens south and west of the area.
/Issued 1232 PM CDT Thu Jun 6 2024/ /Through Friday/ Quiet weather will close out the work week as a mid-level ridge gradually builds over the region.
In addition to these two features, a weak surface trof extends from southeast Louisiana into northeast Alabama and crosses Wayne and Choctaw counties. This weak surface trof is anticipated to linger near this position through the early evening hours. A more well defined cold front meanwhile approaches from the north and eventually catches up with the weak surface trof, with the frontal boundary then moving into the coastal counties on Friday and stalling. Lows tonight range from the upper 60s inland to the lower/mid 70s near the coast. Highs on Friday will be mostly in the lower 90s.
1131 AM CDT Thu Jun 6 2024 (Today through Friday) An upper level ridge builds over our area today into Friday bringing a drier airmass aloft.
1114 AM CDT Thu Jun 6 2024 (Rest of Today) A trough at 8h and 5h across AL into southeast LA will shift southeast of the area today. Dew points will remain in the upper 60s to near 70 this afternoon ahead of the cold front which is still in central IL and MO.
Slightly cooler temperatures today with a further cool down into the weekend. (This evening through Friday) Mid day temperatures running anywhere from 3 to 15 degrees cooler than yesterday depending on location. Overnight lows tonight are expected to be about 1-5 degrees cooler than last night, and highs Friday look to be about 3-6 degrees cooler than today.
- A cold front passage on Friday morning will increase PoPs(40%) immediately along the International Border, with a wetting rain accumulation through Friday night(at least a tenth of an inch) remaining low (<10%). Friday, a quick-moving cold front will move through the region, bringing a low chance for precipitation along the International Border and keep temperatures near to slightly above-normal.
Ridging aloft will continue to build through the short-term range with mostly rain-free conditions persisting across South Texas. In regards to the temperatures, these will be running a few degrees cooler at 850 mb allowing for surface temps to run slightly cooler during the daytime on Friday. The combination of the slightly drier air and cooler temperatures will in turn limit the spread of Heat Advisory conditions tomorrow.
Severe possibilities are very minimal as CAPE values wonât exceed far past 500 J/kg and dewpoints are in the high 40s. Tomorrow: The winds are expected to slightly decrease tomorrow as the low continues to evacuate eastward, with northwesterly/westerly winds averaging in the 10-15 mph range, with some 20-30 mph gusts still possible.
400 PM EDT Thu Jun 6 2024 An unsettled weather pattern is expected the remainder of the week and through the weekend under a persistent upper trough, resulting in periodic chances of isolated to scattered showers. -------------------------------------------------------------- Update at 345 PM focused on upping PoPs a bit into the 30-55 percent range from much of the region as these scattered showers cross, supported by troughing at the surface and aloft. KEY MESSAGES: - Persistent upper trough maintains an unsettled pattern - Cooler temperatures expected ------------------------------------------------------------------- Isolated evening showers will end tonight as the trough exits east.
(This evening through Friday) A cold front will continue through the area today, with scattered showers and thunderstorms expected to develop through the afternoon and evening. The front will move slowly east of the state by midnight tonight, with a high pressure to the west meandering through the south tonight through Friday.
Otherwise, expect warm temperatures tonight, with overnight lows mainly in the low to mid 70s. High pressure will be centered over the area tomorrow, with hot and dry weather prevailing. Expect highs tomorrow afternoon ranging from the mid/upper 90s east, to the low 100s west.
Elsewhere, cumulus is maturing along the higher terrain of western Nevada into Mono County where MUCAPE values of 250-500 J/kg reside. Eastern Pacific troughing will allow for a few degrees of cooling Friday and over the weekend, which will alleviate the heat risk somewhat but temperatures will remain well above average.
1025 AM MDT Thu Jun 6 2024 Mainly sunny, warm and dry conditions with relatively light winds are expected today as upper level high pressure strengthens south and west of the area.
1222 PM CDT Thu Jun 6 2024 (Rest of today through Friday night) Issued at 1115044 AM CDT Thu Jun 6 2024 After a very warm and humid Thursday, passage of a late day cold front will bring cooler and less humid conditions.
1238 PM CDT Thu Jun 6 2024 Today and tonight: Low pressure will begin to shift east as a cold front pushes south across the area today. Storms will gradually shift southeastward as the cold front continues to sag.
132 PM EDT Thu Jun 6 2024 Latest surface observations and KTBW VAD wind profile show low level flow has become more southwesterly as Bermuda high pressure continues to shift further out into the Atlantic and its associated ridge axis shifts southward. We are also seeing cooler temperatures around 500mb ranging from -7 to -10C. For our Friday we are seeing an upper level trough push across the state. As we go through the weekend the trough that will push through on Friday will dry us out in the mid levels allowing for mostly dry and hot conditions.
1215 PM CDT Thu Jun 6 2024 - Scattered showers possible this morning, followed by cooler afternoon temps.
1231 PM CDT Thu Jun 6 2024 - Breezy northwest winds with gusts up into the lower 40s possible. Strongest gusts are expected along the Buffalo Ridge given their elevated elevation.
For tonight, the slightly drier air will lead to lows in the lower 70s in the east, but moisture and low clouds will lead to continued to upper 70s to near 82 degrees in the Rio Grande Counties. Tomorrow night skies should be mostly clear for all areas with lows in the lower to middle 70s for most of the area.
Temperatures are heating up quickly in the deserts this afternoon- current temps are in the low-100s in the lower deserts and near 100 in the High Desert. Highs will cool a few degrees in the mountains and deserts tomorrow as the ridge axis weakens and moves eastward. Slow cooling develops this weekend and the ridge axis continues to move eastward and a longwave trough approaches the West Coast.
An Excessive Heat Warning remains in effect for the lower elevations through 8 PM Friday. This is due to a strong ridge of high pressure aloft, which is taking afternoon highs nearly 20 degrees above normal across the San Joaquin Valley, Sierra Nevada Foothills, and Kern County Desert.
Northwest flow continues today with an area of high pressure moving in from the northwest. The upper level low center will sag into the Great Lakes region and increase winds aloft as well with 850 and 700mb winds valued between 35 and 40kts can be found especially across the north this afternoon. With the influence of the upper level low, some cumulus clouds can be found in the northeast, but with high enough clouds bases, not expecting any rainfall out of these clouds. Beneath the persistent upper-level northwest flow, some ridging will nudge southwesterly winds into the state by midday. An H85 trough will build in the Plains Friday evening and contain the low level jet in Kansas, veering into Missouri overnight.
146 PM EDT Thu Jun 6 2024 Humidity and storm coverage will increase today before a weak cold front moves through early Friday.
Strong high pressure will slowly move east with hot temperatures expected for the next few days. Tonight through Friday night A strong ridge of high pressure will slowly shift eastward, allowing an increase in mid-level moisture and instability.
133 PM EDT Thu Jun 6 2024 A weak cold front moving through the region today will result in the potential for a few showers. High pressure and a drier, cooler airmass will settle into the Ohio Valley tonight into Friday. Generally tranquil weather is expected today between a cold front to the east and high pressure to the west. Any lingering shower activity across our southeast should taper off heading into this evening as the cold front moves through.
140 PM EDT Thu Jun 6 2024 An unsettled weather pattern is expected the remainder of the week and through the weekend under a persistent upper trough, resulting in periodic chances of isolated to scattered showers. KEY MESSAGES: - Persistent upper trough maintains an unsettled pattern - Cooler temperatures expected ------------------------------------------------------------------- Isolated evening showers will end tonight as the trough exits east.
312 PM EDT Thu Jun 6 2024 Unsettled weather continues through this evening as a cold front moves across the area.
(This evening through Friday Night) Quiet weather is anticipated to continue into the weekend, as upper-level ridging continues to meander over Texas.
-A cold front during the overnight hours should turn the humidity dial down tomorrow.
1217 PM EDT Thu Jun 6 2024 An unsettled weather pattern is expected the remainder of the week and through the weekend under a persistent upper trough, resulting in periodic chances of isolated to scattered showers. KEY MESSAGES: - Persistent upper trough maintains an unsettled pattern - Cooler temperatures expected ------------------------------------------------------------------- Isolated evening showers will end tonight as the trough exits east.
- High temperatures will be in the lower 70s to mid 90s. Low temperatures will be in the lower 50s to upper 60s. An upper trough extends from Canada to the Midwest and northern and central Plains. The previously mentioned upper trough will move further east on Friday with another upper trough beginning to move over the northern Plains. High temperatures on Friday will warm up into the low 80s to mid 90s as winds increase out of the south.
413 PM EDT Thu Jun 6 2024 A cold front will approach from the northwest tonight and move through Friday morning.
Around peak heating, expect to see isolated to widely scattered storms develop along this front with the highest chances in western Oklahoma and westward.
232 PM PDT Thu Jun 6 2024 Quiet weather is expected over the next couple days as high pressure builds over the region.
621 PM CDT Thu Jun 6 2024 (Through Tonight) A weak cold front is currently situated south of the KS/OK border. Overnight lows will range from the lower 60s in far northeast OK and far northwest AR to mid-upper 60s elsewhere. Latest forecast model data suggests Friday stays mostly dry as mid/upper-level ridging builds over west TX/east NM. Contrary to previous forecasts, the brunt of the wave is now expected to remain north of the forecast area, but the southern periphery of the trough may clip portions of northeast OK and northwest AR.
830 PM MDT Thu Jun 6 2024 Mainly sunny, warm and dry conditions with relatively light winds are expected today before a weak cold front brings a return to near normal temperatures across the Plains. A weak cold front will move through North-central and Central Montana tonight which will cool Friday's high temperatures to seasonal averages for those locations. A disturbance flattening the high pressure ridge over the area will keep a threat for periods of mountain wave turbulence in the moderate westerly flow aloft.
756 PM EDT Thu Jun 6 2024 An unsettled weather pattern is expected the remainder of the week and through the weekend under a persistent upper trough, resulting in periodic chances of isolated to scattered showers. -------------------------------------------------------------- Update at 345 PM focused on upping PoPs a bit into the 30-55 percent range from much of the region as these scattered showers cross, supported by troughing at the surface and aloft.

Hot temperatures will continue through the end of the week, with isolated showers/thunderstorms across the higher terrain through the weekend.
908 PM EDT Thu Jun 6 2024 An unsettled weather pattern is expected the remainder of the week and through the weekend under a persistent upper trough, resulting in periodic chances of isolated to scattered showers. The showers will largely end by midnight, with at least a brief period of clearing in most locations before additional clouds begin to arrive by sunrise as troughing settles across the Great Lakes.
Highs on Friday look to be about the same or only a degree or so cooler, with less overall cloud cover especially in west central NV compared to today. Elsewhere, cumulus is maturing along the higher terrain of western Nevada into Mono County where MUCAPE values of 250-500 J/kg reside. Eastern Pacific troughing will allow for a few degrees of cooling Friday and over the weekend, which will alleviate the heat risk somewhat but temperatures will remain well above average.
559 PM CDT Thu Jun 6 2024 (This afternoon through Friday night) The short term synoptic pattern is generally dictated by the dominant upper ridge overhead, set to slowly meander eastward through Texas tomorrow. The main headlines under this pattern will be the continued heat, with high temperatures exceeding the triple digits both today and tomorrow afternoon region-wide except the higher elevations and Heat Advisories are in effect today for most zones along and west of the Pecos River. The low-level thermal ridge remains at a similar location/intensity for tomorrow, albeit maybe a degree C cooler, and as such, more Heat Advisories are likely for tomorrow as well. Aside from the heat, the other focus in the short term is on largely diurnally and orographically driven convection across the higher terrain today and tomorrow.
713 PM EDT Thu Jun 6 2024 A cold front will approach from the northwest tonight and move through Friday morning.
Latest forecast model data suggests Friday stays mostly dry as mid/upper-level ridging builds over west TX/east NM. Contrary to previous forecasts, the brunt of the wave is now expected to remain north of the forecast area, but the southern periphery of the trough may clip portions of northeast OK and northwest AR.
Current upper air analysis depicts a ridge over western CONUS with a upper low centered over the Great Lakes region. A strong jet streak (100kts+) is located along the ridge and into the trough entrance resulting in a northwesterly flow over the Northern Great Plains (MT, ND, SD, NE, MN, IA). At the surface, an area of low pressure is centered over Manitoba and Quebec with high pressure located over the Rockies and into Northern Great Plains.
A weak upper trough is moving slowly into SW Oregon which is the triggering mechanism for mainly slight (10-20%) chances over the east side this afternoon and tonight. The NBM has been fairly consistent with advertising temperatures 3 to 7 degrees warmer than today west of the Cascades, well into the 90s for the western valleys and near 90 over the east. Friday's storms should be slightly more numerous and extending further west into the Cascades versus today with a more significant trough approaching.
608 PM CDT Thu Jun 6 2024 (This evening through Friday Night) Quiet weather is anticipated to continue into the weekend, as upper-level ridging continues to meander over Texas.
High pressure will bring hotter temperatures over the next several days. Water vapor this afternoon showed an upper level low SW of the Baja Spur with dense cirrus shield over the area under E-SE flow aloft. The cloud cover hasn't put any dent in the high temperatures with a few areas near record highs. The upper low on Friday will be closer to the Baja Spur with moisture increasing a bit for a little better chance 10%-30% of showers/storms across parts of Greenlee, Graham and Cochise counties.
(Rest of tonight) Lingering cloudiness from earlier today has given way to mostly clear skies this Thu evening, as a weak cold front draped west to east drops into mid TN. This front will continue to move thru the central TN Valley overnight, allowing lows into early Fri to drop mainly into the lower/mid 60s.
613 PM CDT Thu Jun 6 2024 (Rest of today through Friday night) Issued at 1115044 AM CDT Thu Jun 6 2024 After a very warm and humid Thursday, passage of a late day cold front will bring cooler and less humid conditions.
633 PM EDT Thu Jun 6 2024 Another cold frontal passage by late afternoon or evening promotes isolated showers and thunderstorms through midnight.
