As the high pressure center becomes established atop our region, temperatures are expected to be 3-5 degrees warmer compared to yesterday afternoon. The slightly warmer temperatures, coupled with moderate humidity once again this afternoon, will make for yet another uncomfortable afternoon outdoors. The immediate Dallas/Fort Worth Metroplex is likely to remain in the lower 80s tonight. A mid-level ridge will continue scorching North and Central Texas, which is slowly moving its way east to reposition itself across portions of the Southern Plains.
201 AM EDT Fri Jun 28 2024 High pressure building across Pennsylvania and New York tonight will bring quiet weather that should last into Friday. A warm front will lift north Friday night with increasing chances of showers. Showers and thunderstorms are then expected Saturday and Saturday night as a cold front advances south into the warm and humid airmass that will be in place across the Upper Ohio Valley. Positioning of the high will support weak warm, moist advection amid mostly clear skies to raise area temperature about 5 degrees above the daily average solidly into the 80s. Broad ascent may increase mid- to high-level clouds and even offer low probability of showers Friday night as a warm front approaches.
119 AM EDT Fri Jun 28 2024 - Cloudier, warmer, and a bit more humid on Friday. Meanwhile, visible satellite was showing thick cirrus heading this way in WNW upper flow around the lower Mississippi Valley ridge. The NAM, for instance, rapidly brings dew points into the lower 70s by early afternoon across our southern counties.
621 AM CDT Fri Jun 28 2024 (Today through Saturday afternoon) While the upper ridge overhead is being flattened some by a trough cruising through the northern Rockies, this nudges the center of the ridge (and low-level thermal ridge) more over our area. With the ridge center displaced a bit further east on Saturday, the low level thermal ridge falls a few degrees Celsius and high temperatures return to similar values from what was seen yesterday, albeit still quite hot. Under the mild subsidence from the ridge, the only storm chances remain confined to the western high terrain and the higher elevations of southeastern New Mexico both this afternoon and Saturday afternoon.
Hot and muggy conditions persist with afternoon highs in the low to mid 90s with peak heat indices ranging from 102-107 degrees.
With a very weak steering flow in place, localized flooding may become a concern this afternoon over the low lying and poor drainage areas. Overnight low temperatures will range from the low to upper 70s.
341 AM PDT Fri Jun 28 2024 Mild, mostly dry weather likely Friday, followed by warmer temperatures Saturday.
641 AM CDT Fri Jun 28 2024 (Today through Saturday Night) An upper level ridge is working its way eastward toward Arkansas this morning. The upper ridge will be over Arkansas Saturday and will remain in place through Saturday night. High pressure and subsidence will keep dry conditions over the state through early Saturday. A cold front will drop out of the Plains into north Arkansas Saturday evening. Warm conditions will continue today but warmer conditions are expected Saturday. Lows tonight will be in the 70s and in the lower 70s to near 80 degrees Saturday night.
- Quiet and cooler for the weekend, with highs in the mid 70s to lower 80s. Today and tonight: A mid/upper-level low and associated trough from southern parts of Alberta and Saskatchewan into the northern Rockies and adjacent High Plains will track southeast into the northern Plains and upper MS Valley by tonight.
This is due to a persistent trough over the Pacific Northwest, which has turned mid-level flow back to westerly. Small variations in the northern stream trough will allow flow to turn more southerly at times over the next several days.
602 AM EDT Fri Jun 28 2024 High pressure builds today, then slowly exits to the east through Saturday.
Afternoon highs the next few days will top out in the lower to mid 90s, but heat index values will reach into the 100-105 range.
The high pressure sitting across our region will weaken a bit. This means slightly cooler temperatures for the weekend by a couple of degrees.
321 AM MDT Fri Jun 28 2024 KEY MESSAGES: 1) Breezy conditions are expected today behind a cold front, with gusts up to 50 mph accelerated by rain showers.
627 AM EDT Fri Jun 28 2024 High pressure brings fair weather today into Saturday morning. Low pressure tracking east across Quebec will lift a warm front into the area late Saturday bringing rain.
611 AM CDT Fri Jun 28 2024 Hot temperatures return today and will last through Saturday as a strong upper level ridge dominates weather patterns.
The coastal pressure gradient will continue to enhance diurnally driven NW winds this afternoon as Pacific high pressure builds into the interior thermal trough. Surface RH's will be slightly elevated as this trough sustains marine influence for coastal counties through the weekend, with interior valleys not expected to drop below 20- 25% min daytime RHs.
A ridge axis analyzed across Central Florida has resulted in light to gentle east to southeasterly breezes along the Reef with more southerly flow located closer to South Florida. A lack of shower activity and cloud cover will allow for temperatures to reach highs into the lower 90s this afternoon. From synopsis, the low level ridge axis currently across the Florida Keys will shift north today through Saturday.
(Today through Saturday) A 500mb ridge centered over northern Texas will be the dominate feature for Deep South Texas through the period. However, a weak inverted mid-level trough moving under the ridge, combined with precipitable water values around two inches, will result in isolated seabreeze showers and thunderstorms today.
Still looking for the highest chances of showers and storms across the higher terrain along the Appalachians. Discussion: Some very weak short wave energy moving across the area early this morning may support a few showers mainly south early this morning, but heights will be rising today as upper ridging builds. Highs today will generally be in the lower 90s across valley locations.
The highs today will still manage to hit 90 deg or the lower 90s for most areas.
639 AM CDT Fri Jun 28 2024 (Today through Saturday Night) High pressure will continue to reign over SE Texas today with onshore flow continuing to funnel in moisture. This moisture will continue to be trapped under this dome of high pressure, continuing the streak of hot and humid days. Lows for tonight and Saturday night will continue to be on the warmer side as temperatures drop into the upper 70s to around 80Â°F As the streak of heat continues, please remember to practice heat safety! Stay hydrated, avoid strenuous activity at the hottest part of the day, and LOOK BEFORE YOU LOCK! Also, for pets.
508 AM MDT Fri Jun 28 2024 -Breezy today with cooler temps.
Last nights 500 mb upper air map placed the upper high over northern Sonora with westerly flow over the area.
206 AM PDT Fri Jun 28 2024 Mild, mostly dry weather likely Friday, followed by warmer temperatures Saturday.
(Today through Saturday) Upper ridging building eastward early this morning, but is elongated northeast to southwest from Baja California to Texas to Arkansas, instead of the east-west formation that has been forecasted. A shear axis or weak trough extended from the Carolinas to near Mobile to the western Gulf of Mexico. The ridge just to the northwest is forecast to strengthen a bit while the shear axis weakens.
618 AM CDT Fri Jun 28 2024 (Today through Saturday) A 500mb ridge centered over northern Texas will be the dominate feature for Deep South Texas through the period. However, a weak inverted mid-level trough moving under the ridge, combined with precipitable water values around two inches, will result in isolated seabreeze showers and thunderstorms today.
1255 PM CDT Fri Jun 28 2024 (Today through Saturday Night) An upper level ridge is working its way eastward toward Arkansas this morning. The upper ridge will be over Arkansas Saturday and will remain in place through Saturday night. High pressure and subsidence will keep dry conditions over the state through early Saturday. A cold front will drop out of the Plains into north Arkansas Saturday evening. Warm conditions will continue today but warmer conditions are expected Saturday. Lows tonight will be in the 70s and in the lower 70s to near 80 degrees Saturday night.
Lift is currently provided by the slowly moving mid level trough which will continue to move out of the area through tomorrow (trending forcing downward on it's way). Temperatures today and tomorrow will be in the low to mid 90s. Heat indices will reach 100 to 104 for all but the higher elevations of North GA.
351 PM EDT Fri Jun 28 2024 Bermuda high pressure will dominate again as a lingering front retreats northward with increasing heat through the weekend.
1032 AM MDT Fri Jun 28 2024 -Breezy today with cooler temps.
(This afternoon through Saturday night) A rather pedestrian forecast continues under the influence of an upper ridge elongated W-E and and centered over the great state of Texas this afternoon. As was the case yesterday, instability this afternoon looks minimal, and CAMs struggle to develop convection over the higher terrain. Saturday, the ridge shifts east, taking the focus off West Texas and Southeast New Mexico. CAMs once again are not very enthusiastic in developing convection Saturday afternoon, keeping better chances west and out from under the ridge. Another LLJ develops Saturday night, but temperatures may come in a couple of degrees cooler than tonight simply because Saturday is not expected to be as warm as today.
(Now through Saturday) Rinse and repeat, the summertime theme! Subtle troughing remains in place over the southeastern US with upper ridging remaining to our west.
High pressure is now situated to our east, so we're picking up some return southerly flow that is sending our temperatures soaring while also slowly increasing our dew points.
1020 AM CDT Fri Jun 28 2024 Temperatures across the Mid-South have warmed into the low to mid 80s with dewpoint values ranging from the low to mid 70s. This is resulting in heat index values in the low to mid 90s. Temperatures are still expected to warm into the low 90s today which should yield heat index values near 100 degrees across most of the region. JPR Hot temperatures return today and will last through Saturday as a strong upper level ridge dominates weather patterns.
A cold front is expected to bring slightly cooler and drier conditions to start off the work week, but building high pressure will allow the return of temperatures near the century mark by mid- week. Deep moisture continues to pool across the area with PWAT's rising to around 2" today as ridging builds aloft.
1235 PM CDT Fri Jun 28 2024 (Today through Saturday) A 500mb ridge centered over northern Texas will be the dominate feature for Deep South Texas through the period. However, a weak inverted mid-level trough moving under the ridge, combined with precipitable water values around two inches, will result in isolated seabreeze showers and thunderstorms today.
Tonight and Saturday Afternoon satellite imagery shows an upper low centered across northeastern MT today while closer to home, we have some fast moving cirrus clouds streaking across the region. High pressure continues to build over the area and temperatures are running slightly below average today. The heat returns with avengeance tomorrow as the upper ridge really amplifies overnight and into the day Saturday. Expecting daytime highs in the upper 80s to lower 90s across the lower valleys tomorrow.
Hot conditions will continue through Saturday as ridging continues to amplify over the Mid-South. A cold front will bring increasing rain chances to the region starting Saturday, with the potential for strong to severe thunderstorms across portions of the Missouri Bootheel and northeastern Arkansas.
1146 AM CDT Fri Jun 28 2024 (Today through Saturday Night) High pressure will continue to reign over SE Texas today with onshore flow continuing to funnel in moisture. This moisture will continue to be trapped under this dome of high pressure, continuing the streak of hot and humid days. Lows for tonight and Saturday night will continue to be on the warmer side as temperatures drop into the upper 70s to around 80Â°F As the streak of heat continues, please remember to practice heat safety! Stay hydrated, avoid strenuous activity at the hottest part of the day, and LOOK BEFORE YOU LOCK! Also, for pets.
A ridge building over the region today will keep the weather nice through tomorrow.
Looking into the weekend, more moisture is on the way thanks to the high pressure reconsolidating to the east over Northern Texas introducing moist southeast flow instead of the dry west/southwest flow that we currently have in place.
1052 AM CDT Fri Jun 28 2024 (Today through Saturday afternoon) While the upper ridge overhead is being flattened some by a trough cruising through the northern Rockies, this nudges the center of the ridge (and low-level thermal ridge) more over our area. With the ridge center displaced a bit further east on Saturday, the low level thermal ridge falls a few degrees Celsius and high temperatures return to similar values from what was seen yesterday, albeit still quite hot. Under the mild subsidence from the ridge, the only storm chances remain confined to the western high terrain and the higher elevations of southeastern New Mexico both this afternoon and Saturday afternoon.
/NEW/ /Through Saturday/ With the upper ridge settled directly overhead, hot and dry conditions will prevail through the remainder of today and Saturday.
/Issued 109 PM CDT Fri Jun 28 2024/ /Through Saturday/ With the upper ridge settled directly overhead, hot and dry conditions will prevail through the remainder of today and Saturday.
As we go toward daybreak, activity should wane in the wake of the MCV as subsidence spreads over the area, and a dry period may occur as a cold front sags southeast through southern WI. A secondary cold front will move through during the afternoon hours, and with the morning cold front providing clearer skies and leaving some 60 to 65 degree dewpoints behind, SBCAPE should build to 1500 J/kg in an environment marked by 30 knots of effective shear.
243 PM EDT Fri Jun 28 2024 High pressure will move off the New England coast tonight.
230 PM MDT Fri Jun 28 2024 The area of low pressure bringing increased winds to the area today will gradually progress east into the Dakotas tonight. Temperatures tonight will be cooler than last night with lows in the 40s to lower 50s.
Friday will stay dry and cooler than normal as colder air exits east and a ridge begins to build. The ridge's strength will peak on Saturday bringing a sharp warm up from Friday with temps 5-10 degrees above normal. Light- moderate winds on Saturday ahead of an approaching cold front late Saturday night. The cold front comes associated with an upper trough bringing slightly wetter weather with building clouds and precipitation.
A drier southwest flow will be over northern Arizona the next couple of days, thanks to persistent troughing across the northwestern U. Subtropical high pressure over the southern plains will gradually build west later this weekend, leading to a transition back to south/southeasterly flow.
1052 AM PDT Fri Jun 28 2024 Mild, mostly dry weather likely Friday, followed by warmer temperatures Saturday.
The DCAPE in the sounding is around 1400 J/kg and the RAP keeps the higher values north and west of Tucson, but still holds on to 1000 J/kg in its forecast for 23Z. CAMs continue to have storm develop starting at 1pm over the higher terrain and continuing into the evening. Last nights 500 mb upper air map placed the upper high over northern Sonora with westerly flow over the area.
Low level moisture will allow for a more widespread cloud deck to develop overnight into Saturday morning keeping low temperatures a couple degrees warmer than those seen previous nights.
Southwesterly flow will continue across the region today and tomorrow as the ridge axis remains just south of the region.
144 PM MDT Fri Jun 28 2024 KEY MESSAGES: 1) Breezy conditions and scattered heavy rain showers will wind down by midnight tonight as the low pressure system departs into North Dakota.
Along the Reef, light to gentle east to southeasterly breezes have reestablished themselves after a period of variability this morning and with the gradual northerly drift of the ridge axis over Central Florida. Tonight and through tomorrow, breezes will back to the east and freshen slightly as the ridge axis over Mainland Florida drifts north.
1235 PM CDT Fri Jun 28 2024 Temperatures across the Mid-South have warmed into the low to mid 80s with dewpoint values ranging from the low to mid 70s. This is resulting in heat index values in the low to mid 90s. Temperatures are still expected to warm into the low 90s today which should yield heat index values near 100 degrees across most of the region. JPR Hot temperatures return today and will last through Saturday as a strong upper level ridge dominates weather patterns.
(This evening through Saturday) Upper level ridging will remain firmly in control as we head into the weekend. 850mb temperatures, however, are forecast to be a couple degrees cooler on Saturday compared to today.
(Tonight through Saturday night) An upper-level ridge over Central Texas will slowly lift to the north this weekend, as an inverted mid-level trough moves across the southern Gulf. Heat Advisories may be needed for the eastern counties, however confidence is low on the spatial and temporal coverage of the higher heat index values.
128 PM EDT Fri Jun 28 2024 High pressure will move off to the east today. Southerly flow around the departing high will bring warmer, more humid air back into the region.
/NEW/ /Tonight through Saturday Night/ Mid level ridging will remain firmly in control of the weather across North Texas through the weekend with hot and humid conditions expected to continue. There will be a weak cold front to our north across Oklahoma where convection will likely be scattered throughout the late afternoon/evening.
This is likely due to the lower levels remaining relatively dry. This is because the tropical disturbance nearing the Yucatan Peninsula is pulling further away from the Keys and ridging is being allowed to settle back in across the area.
406 PM CDT Fri Jun 28 2024 (This afternoon through Saturday night) A rather pedestrian forecast continues under the influence of an upper ridge elongated W-E and and centered over the great state of Texas this afternoon. As was the case yesterday, instability this afternoon looks minimal, and CAMs struggle to develop convection over the higher terrain. Saturday, the ridge shifts east, taking the focus off West Texas and Southeast New Mexico. CAMs once again are not very enthusiastic in developing convection Saturday afternoon, keeping better chances west and out from under the ridge. Another LLJ develops Saturday night, but temperatures may come in a couple of degrees cooler than tonight simply because Saturday is not expected to be as warm as today.
837 PM MDT Fri Jun 28 2024 A warm and dry evening is expected as a weak upper-level ridge develops over the forecast area in response to an approaching upper-level trough anticipated late Saturday. The next upper-level trough and associated cold front will move across the Pacific Northwest, reaching southeast Oregon around 6 PM MDT.
This combined with southerly flow will help keep temperatures on the warmer side, only falling into the low to mid 70s.
A cold front is expected to bring slightly cooler and drier conditions to start off the work week, but building high pressure will allow the return of temperatures near the century mark by mid- week. Abundant moisture in the low levels remains in place overnight and expect another round of stratus and possible fog to develop during the predawn hours over the Coastal Plain and eastern Midlands which is expected to spread into the central Midlands.
The coastal pressure gradient will continue to enhance diurnally driven NW winds this afternoon as Pacific high pressure builds toward the interior thermal trough. Many interior valleys are currently in the high 80s to low 90 degrees already, and temps are expected to continue to climb for the next hour or two. NW winds 5-15 mph are forecast across the interior through late Saturday night, with gusts reaching 20-30 mph on exposed ridges. Surface RH's will be slightly elevated as this trough sustains marine influence for coastal counties through the weekend, with interior valleys not expected to drop below 20 to 25 percent min daytime RHs.
631 PM CDT Fri Jun 28 2024 (This evening through Saturday) Upper level ridging will remain firmly in control as we head into the weekend. 850mb temperatures, however, are forecast to be a couple degrees cooler on Saturday compared to today.
804 PM EDT Fri Jun 28 2024 High pressure will cross the region tonight, then slowly exit to the east Saturday.
450 PM PDT Fri Jun 28 2024 Mild and mostly dry weather on Friday will be followed by warmer temperatures Saturday.
High pressure aloft will dominate the weather picture over the West for the foreseeable future. A weak trough to our northwest and a big ridge to our east will jockey for position over SoCal this entire coming week. The ridge will gain the upper hand and bring the hot weather. An Excessive Heat Watch is now in effect for all desert regions, where temps will rise to about 113-116 in the lower desert, up to 106-109 in the high desert.
Saturday will feature the ridge axis slowly nudging its way northward across the peninsula, favoring a more typical easterly flow for areas south of I-4, with shower/storm chances greatest late afternoon into the evening, while areas to the north will likely have lighter flow remaining a bit more out of the W-SW with greatest shower/storm chances a bit earlier in the afternoon before gradually diminishing into the evening. Southwesterly flow will continue across the region today and tomorrow as the ridge axis remains just south of the region.
959 PM EDT Fri Jun 28 2024 High pressure will cross the region overnight, then slowly exit to the east Saturday.
Cold front moves through Saturday night and leaves a relatively cooler and drier air mass for the end of the weekend and start of the next work week. With southerly flow and cloud cover overnight, expect temperatures to only drop into the lower to middle 70s. A longer period without rainfall in our south could lead to some locations near 100 degree heat indicies given that dewpoints are expected to climb into the lower to middle 70s. Cold front begins to move through our CWA Saturday night, but by then, forcing appears more limited and thus coverage in precip will be more limited too.
202 PM PDT Fri Jun 28 2024 Mild and mostly dry weather on Friday followed by warmer temperatures Saturday.
911 PM CDT Fri Jun 28 2024 A warm night is on the horizon as current temperatures are in the low to mid 80s with light south/southeast winds at the surface under mostly clearly skies across the Mid-South as we sit under amplified mid-level ridging. Tomorrow's afternoon highs will skyrocket into the mid to upper 90s as mid-level ridging continues to build across the region, leading to dangerously hot conditions.
625 PM CDT Fri Jun 28 2024 (Tonight through Saturday night) An upper-level ridge over Central Texas will slowly lift to the north this weekend, as an inverted mid-level trough moves across the southern Gulf. Heat Advisories may be needed for the eastern counties, however confidence is low on the spatial and temporal coverage of the higher heat index values.
611 PM CDT Fri Jun 28 2024 Hot conditions will continue through Saturday as ridging continues to amplify over the Mid-South. A cold front will bring increasing rain chances to the region starting Saturday, with the potential for strong to severe thunderstorms across portions of the Missouri Bootheel and northeastern Arkansas.
