- Heat index values have climbed over 100 across areas south of the warm front this afternoon, and should fill in northward across much of the remaining advisory area over the next few hours. - A cold front will bring northerly winds and mild temperatures to the area Tuesday, slowly crossing the local area through the daytime hours.
138 AM EDT Tue Jul 2 2024 High pressure will shift off to the east tonight through Tuesday.
1138 PM EDT Mon Jul 1 2024 High pressure will build in through Tuesday, then exits across the Maritimes through Wednesday.
Tad warmer today area wide, and dry weather to persist. The upper level ridge will begin to build back in over our area, and winds will switch back to a up valley southwesterly flow regime. Should be a slightly warmer, slightly muggier day than yesterday was, but overall still pretty nice. Tonight will feature still mostly clear skies, light winds under the ridge, and dry conditions.
A drier and much warmer pattern will set up by the end of the work week.
1231 AM EDT Tue Jul 2 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.
(Today) Temperatures early this morning remain in the lower 80s in many locations as gusty south winds persist. Dangerous heat will continue today as upper ridge continues to dominate the overall weather pattern.
323 AM EDT Tue Jul 2 2024 High pressure brings dry weather into Wednesday.
The center of the mid-level ridge will continue atop North Texas today, keeping above normal temperatures in the forecast today and tomorrow. This afternoon's temperatures will be a few degrees warmer compared to yesterday. As the ridge weakens some tomorrow, temperatures will be a few degrees lower. /Issued 218 PM CDT Mon Jul 1 2024/ /Wednesday and Beyond/ North and Central Texas will remain under the influence of a stout upper ridge through the middle portions of this week keeping mostly sunny, hot, and dry weather through the 4th of July holiday.
(Today and tonight) An upper level ridge centered across the Southeast U.
Satellite imagery shows cumulus developing across areas that got a break from the mid-level clouds across the high country and east plains and Lincoln County. A weak cold front moves through early Tuesday morning with potential for development of low stratus behind it. Tuesday, the upper level trough remains over the region.
1040 PM MDT Mon Jul 1 2024 -Severe storms this afternoon and evening -Daily chances for showers and thunderstorms -Temperatures near average Wednesday, and slightly below average the rest of the week -Warmer and drier this weekend Upper level analysis has a trough over the Intermountain West with a ridge over the Central Great Plains, resulting in southwest flow over the forecast area. Temperatures will be cooler though, with highs slightly below average in the low 70s to low 80s. On Wednesday, the upper flow starts our more more zonal, but the main upper trough starts to dig over Montana and Wyoming ejecting an impulse across the forecast area in the afternoon.
Despite the cool start, the heat and humidity will be making a comeback today as an upper level ridge quickly builds over the Tennessee Valley and Gulf moisture returns from the south. Highs are anticipated to reach the low to mid 90s for most of the midstate with dewpoints rising back into the 60s to around 70. Wednesday looks even hotter and more humid as the center of the upper ridge settles just to our south, with highs in the mid to upper 90s and dewpoints rising further into the low to mid 70s. (Wednesday Night through next Tuesday) Another very hot and humid day is anticipated for July 4th with highs once again in the low to mid 90s and dewpoints remaining in the 70s.
Another trough embedded within northwesterly flow will provide modest atmospheric instability (CAPE 100-250 J/kg) and lift for shower and storm development.
314 AM EDT Tue Jul 2 2024 High pressure will be in control of the weather across the region through Wednesday.
- Warmer and dryer the remainder of the week and weekend with increasing fire weather risk. Otherwise, the backside of the low with a weaker mid level support trough with spark more isolated storms (30-40% coverage) Tuesday afternoon across the northern half of the CWA. Otherwise, expect the cooler than average temperatures to continue for Tuesday until the longwave trough pushes east and the main finger of the PFJ retreats back to the north. A strong upper level high will being to build from the desert Southwest with increasing convergence aloft toward the end of the week and especially over the weekend.
Winds are southerly and temperatures remain in the lower 80s. Temperatures Wednesday may be a degree or two cooler and again not anticipating any need for heat headlines. The short-term period will remain dry with upper level high pressure continuing over the region.
Look for highs in the low 90s with HI values nearing triple digits tomorrow afternoon. The upper high will slide back east overnight and reassert its dominance starting tomorrow.
336 AM EDT Tue Jul 2 2024 High pressure will build across the region through early this week, keeping the weather pleasant and dry through at least early Wednesday. The day will begin sunny, and increasing afternoon cumulus clouds are anticipated, especially over the higher terrain. A warm front lifts north into our region overnight, and we'll mainly just see an increase in clouds with this feature, as well as mild overnight temperatures.
Water vapor imagery highlights a broad mean-layer ridge over the Mississippi River Valley. A long wave trough has amplified off the Eastern Seaboard, while the ITCZ over the eastern Pacific finally has started to percolate.
Looking ahead at the remaining weather for today, things should remain quiet with the ridge over the southern CONUS. As the ridge continues to degrade, there are more opportunities for precipitation throughout the rest of the week.
KEY MESSAGES: - Dry and warmer today. ------------------------------------------------------------------- 500mb ridge axis will move over the region this afternoon. This setup will allow for dry weather, plenty of sunshine, and warmer temperatures.
1044 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.
Strong onshore flow overnight will generate a cloudy morning across western Washington, causing temperatures to be a few degrees cooler tomorrow. Tuesday is on track to be the coolest day of the foreseeable future ahead of much warmer and dry conditions with a strong high pressure ridge on track to develop over the southwestern US. Near-normal temperatures through Wednesday but a strong upper-level ridge looms upstream.
1204 AM CDT Tue Jul 2 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.
126 AM EDT Tue Jul 2 2024 High pressure will be in control of the weather across the area, bringing fair weather and increasing temperatures through Wednesday.
KEY MESSAGES: - Dry and warmer today. 500mb ridge axis will move over the region this afternoon. This setup will allow for dry weather, plenty of sunshine, and warmer temperatures.
221 AM EDT Tue Jul 2 2024 High pressure will pass over the region maintaining dry weather through Wednesday. It is a mostly clear night with high pressure centered over NY State, and extending over the Mid Atlantic region. Aloft, ridging builds in with rising heights.
206 AM EDT Tue Jul 2 2024 High pressure will build over the region today. A ridge of high pressure will build over the forecast area today. Under mostly sunny conditions and good mixing this afternoon, expect a warmer day with temperatures reaching the lower to mid 80s away from the shoreline. Along the immediate coast, temperatures will be cooler with a sea breeze developing by afternoon. High pressure will remain over the region tonight. The ridge will slide off the coast on Wednesday allowing a trough to approach from the west. Right along the coastline, southerly winds will be on the increase and keep things cooler as winds remain off the Gulf of Maine.
(Today and tonight) Mid to upper ridging which has been centered overhead the past few days will begin to shift slowly eastward today. In addition to the heat, a cold front will bring a chance for thunderstorms to northwest Oklahoma by mid to late afternoon.
1234 AM CDT Tue Jul 2 2024 (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.
229 AM EDT Tue Jul 2 2024 High pressure brings dry weather through Wednesday.
The persistent mid-level ridge across the southern CONUS begins to weaken slightly over the southern Great Plains as the center moves eastward slightly. Unfortunately, this slight shift of the ridge increases temperatures a few degrees across the area.
Isolated to scattered showers and thunderstorms will develop each afternoon through Wednesday, before drier and warmer conditions set in for the holiday weekend. For Tuesday and Wednesday, expect the chances for precipitation to decrease as temperatures begin to increase, all thanks to a building ridge of high pressure just off the West Coast. As the high strengthens towards the west, west-northwesterly flow becomes more enhanced, forcing moisture towards the south and east.
Conditions remain largely unchanged with high pressure continuing to maintain a hold over SE Texas. The abundant moisture trapped under the ridge of high pressure will combine with increasing temperatures and lead to heat indices reaching into the 105-110F range through the near-term period.
320 AM EDT Tue Jul 2 2024 Dry and relatively cool high pressure will remain in place today, before temperatures start warming back up tomorrow and beyond.
We will be hitting the low end for LAKE WIND thresholds on American Falls Reservoir, so we will see if the trend continues later today for the potential for any type of headline.
The surface inverted trough that sparked off last night and this morning's activity has shifted to our west. There is a mid level inverted trough still nearby but it remains to be seen if it can trigger new convection. High pressure over the western North Atlantic will maintain gentle to moderate easterly breezes across the Florida Keys.
Along the breeze isolated SHRA/TSRA are possible, with the highest coverage expected from the Treasure Coast terminals to MCO/ISM/LEE by 22z-02z Wed. The ECSB continues to make steady progress inland this evening, though with the warmer temperatures aloft, we have only observed ISOLD convection. The Atlc ridge axis draped across central Florida today will lift north of the local waters by midweek allowing dominant wind flow to be from the SE becoming enhanced (10-15 knots) each afternoon near the coast behind the sea breeze.
19z subjective analysis reveals a short wavelength ridge axis from northeast to southeast across the forecast area.
(Today through Wednesday) Upper-level (H500) ridging will gradually expand further over the southeastern CONUS, allowing for an easterly to southeasterly mean steering flow to prevail across South Florida.
355 AM CDT Tue Jul 2 2024 Today and Tonight: The strong upper-level ridge sliding east along the Gulf Coast will be directly overhead today, resulting in subsidence and weak flow as prevailing influences across our forecast area. The dry air mass which brought some refreshingly cooler temperatures to northern and central parts of the area this morning will be squeezed northward as an easterly wave moves into the area. The returning moisture also means low temps tonight will once again be about 5 degrees warmer than normal.
1246 AM EDT Tue Jul 2 2024 - Cooler temperatures and dry conditions persist through Tuesday. - Heat and humidity substantially increase Wednesday with dewpoints in the low 70s, highs in the upper 80s to low 90s, and (along the US 24 corridor) heat indices in the mid to upper 90s.
1134 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 main concern with this activity would be the potential for strong wind gusts due to the well mixed boundary layer and cloud bases near the freezing level.
Low and mid level ridging entrenched locally early this morning. Trailing cold front arrives Wednesday.
Water vapor satellite imagery early this morning shows a trough digging into the northern/central plains with widespread convection across eastern Nebraska and western Iowa. Meanwhile, a jet max will round the base of the passing upper trough, and much of Kansas will reside in the right entrance region of the jet max. A strong MCS is expected to develop across the High Plains Wednesday afternoon, but the eastward extent will be called into question given the lack of instability across the forecast area from shower and thunderstorm activity expected throughout the day on Wednesday.
1012 AM EDT Tue Jul 2 2024 Cool and dry high pressure will remain in control through tomorrow.
659 AM CDT Tue Jul 2 2024 Today and Tonight: The strong upper-level ridge sliding east along the Gulf Coast will be directly overhead today, resulting in subsidence and weak flow as prevailing influences across our forecast area.

625 AM CDT Tue Jul 2 2024 (Today) Temperatures early this morning remain in the lower 80s in many locations as gusty south winds persist. Dangerous heat will continue today as upper ridge continues to dominate the overall weather pattern.
A very broad area of high pressure will continue to dominate the South Central CONUS states through Wednesday. /KP/ Today and Tonight: The strong upper-level ridge sliding east along the Gulf Coast will be directly overhead today, resulting in subsidence and weak flow as prevailing influences across our forecast area. The dry air mass which brought some refreshingly cooler temperatures to northern and central parts of the area this morning will be squeezed northward as an easterly wave moves into the area. The returning moisture also means low temps tonight will once again be about 5 degrees warmer than normal.
611 AM EDT Tue Jul 2 2024 High pressure brings dry weather into Wednesday.
709 AM EDT Tue Jul 2 2024 Cool and dry high pressure will remain in control through tomorrow.
712 AM EDT Tue Jul 2 2024 (Today through Wednesday) Upper-level (H500) ridging will gradually expand further over the southeastern CONUS, allowing for an easterly to southeasterly mean steering flow to prevail across South Florida.
Two more cooler than normal days, along with scattered showers/thunderstorms will continue over the CWA. With an upper level trof slowly moving through the CWA over the next 2 days, we will have a chance for scattered showers/thunderstorms both days. The upper level ridge will try to move east of the CWA today. Thus there will be a small chance for a light shower through late afternoon, the North Central MT having the highest chances.
High pressure influence gradually wanes today as it shifts further east. Mid/upper clouds stream into the area through the day as Plains low pressure tracks toward the Midwest. Low and mid level ridging entrenched locally early this morning. Trailing cold front arrives Wednesday.

648 AM EDT Tue Jul 2 2024 Mild temperatures for July are expected today and Wednesday as high pressure builds in from the north. As the high moves offshore later this week, increasing heat and humidity could lead to dangerous heat indices developing by the weekend. Weak low pressure has formed along this frontal boundary, allowing for some isolated light showers to fall over the adjacent coastal waters. NE to ENE winds persist today and tonight, allowing for the cooler air to stick around. Lows tonight in the low-to-mid 60s inland, lower 70s at the coast. The subtropical ridge at 500 mb should remain centered across Alabama and Georgia, close enough for a warm convective cap to remain over the eastern Carolinas between 600-700 mb.

- A cool and pleasant Independence Day is expected in the wake of a strong cold front set to sweep across the area on Wednesday night. We should see a brief warm up on Wednesday w/ short wave ridging in advance of the next sharp trough. Substantial WAA at 700-mb will contribute to some questions w/ the eastward extent of the EML & thus the impact of capping on overall coverage of storms in some portions of the CWA, but the primary focus for Wednesday will be northern & eastern zones along the edge of the thermal ridge for potential thunderstorm development. Notable veering wind profiles in the low levels suggests a few tornadoes will also be possible if storms can remain at least quasi discrete.
920 AM EDT Tue Jul 2 2024 Mild temperatures for July are expected today and Wednesday as high pressure builds in from the north. As the high moves offshore later this week, increasing heat and humidity could lead to dangerous heat indices developing by the weekend.

Currently have an upper trough swinging across the Northern/Central Plains with upper ridging over the Southeast CONUS. At the surface, cold front stretches from southeast KS to south of KRSL and into the OK Panhandle. Still looking for storms to develop along the cold front late this afternoon or early evening. Confidence is high that this will result in an MCS coming off the High Plains Wed night. By Thu afternoon, upper vort max will be tracking across Nebraska with another cold front expected to be pushing south across the area. Still looking like a break from storms for both Fri and Sat as we get into northwest flow aloft with strong upper ridging over the Western CONUS.
