/Issued 117 AM CDT Wed Jun 26 2024/ /Through Thursday/ A cluster of storms in southern Oklahoma has exhibited a weakening trend as it continues moving south late this evening. Most (if not all) of this activity is expected to dissipate prior to reaching the Red River, but low (20%) PoPs have been introduced through the morning hours in the event a few showers or storms are able to survive the journey into North Texas. We`ll have additional opportunities for showers and thunderstorms throughout the day. The first will be associated with a complex of thunderstorms that has developed from Nebraska into Iowa and Missouri. This system will continue moving south and may skirt portions of eastern North and Central Texas later today. Additional thunderstorm development may occur with any outflow boundary from the dissipating cluster of storms in Oklahoma, mainly during peak heating this afternoon. A few strong to marginally severe storms with hail and gusty winds will be possible, especially during the afternoon hours, but marginal deep layer shear will preclude a greater severe weather threat from materializing. Low storm chances will linger into Wednesday night across our eastern zones with the passage of another weak shortwave, but rain chances should shut off as mid-level ridging builds in again on Thursday. Aside from the rain chances, summer heat will continue to plague the region. High temperatures will range from the mid 90s to around 103 degrees with heat index values between 105-110 for most locations. While there is some bust potential with the current Heat Advisory today given the potential for rain, no adjustments will be made due to the uncertainty in location and coverage of storms through the afternoon. Heat Advisory criteria will be met for most locations again on Thursday, so expect an extension through Thursday at some point tonight or later today. Barnes

/NEW/ /Thursday Night Through Tuesday/ The upper ridge, which has been centered west of the Lone Star State the past few days, will briefly deamplify while shifting to the east Thursday night through Saturday. Increasing subsidence will keep the weather rain free and continued hot with highs ranging from the middle 90s to around 103. Dew points will also stay in the 70s overall, except for some brief afternoon mixing into the upper 60s across the west. Therefore, afternoon heat index values will still average between 105 and 110 for most locations. The brief deamplification of the ridge will be a result of a strong shortwave sweeping across the Northern and Central Plains. The passage of the shortwave will also send a cold front southward through the Central Plains Saturday. The front is progged to stall over Oklahoma on Sunday, but it will be a source of lift for thunderstorms. A few storms could briefly reach the northeast zones as they propagate southeastward on the periphery of the upper ridge, mainly Sunday afternoon. High pressure will become centered near the ArkLaTex early next week, keeping the hot and humid weather in place as we start the month of July. Temperatures and heat index values will be very similar to this week. Therefore, a Heat Advisory will likely remain for part, if not all of the region early next week. One thing that could become an issue as we move deeper into summer will be the threat for fire starts as fine fuels begin to dry under the extreme heat. The good news is that this time of the year, wind speeds are typically light, keeping the threat for significant fire spread low. Recent high humidity has also helped to keep the overall threat for fire starts and spread low but humidity can change quickly with even subtle airmass modification and wind shifts. Again, there is no immediate fire threat expected with this forecast package, but the threat may start to creep up across parts of North and Central Texas as we move through July. 79

/Issued 117 AM CDT Wed Jun 26 2024/ /06Z TAFs/ A cluster of storms in southern Oklahoma has recently exhibited a weakening trend as it moves south. Most (if not all) of this activity should dissipate before crossing the Red River later this morning, but a stray shower or storm can`t be ruled out in North Texas through the morning hours. Additional storms will be possible throughout the day, mainly across eastern North and Central Texas, but this activity is expected to remain east of the terminals. MVFR stratus is expected later this morning, but will likely remain patchy across D10. Otherwise, VFR will continue through the period with southerly winds near 8 to 12 knots. Barnes
