A strong high pressure ridge aloft produced temperatures above 100 degrees along with heat index values at or above 110 degrees for most of North and Central Texas during a couple of days in late June. Amid ongoing Heat Advisories, much of the region was placed under an Excessive Heat Warning between June 27-29, 2024.

Area Forecast Discussion National Weather Service Fort Worth TX 754 AM CDT Thu Jun 27 2024 ...New Aviation, Short Term... .SHORT TERM... /NEW/ Update: The previous forecast remains in good shape, so no major changes were necessary with this morning's update. Low chances for showers and storms will linger throughout the day, though most locations will remain dry. Otherwise, hot and humid conditions will continue across the region. Barnes Previous Discussion: /Through Friday/ Our evening thunderstorms near the Red River have dissipated, but some low rain chances will linger across our eastern zones through the morning as showers and storms continue to develop ahead of a weak frontal boundary. While most of this activity should remain just to our east, we'll carry some low (20%) PoPs in the event we see some development further west than what is currently being observed. Most areas will remain rain-free throughout the day, but with the front draped from NW to SE across the region, additional isolated showers and storms are expected to develop during peak heating this afternoon near and south of boundary. Afternoon temperatures will climb into the mid 90s to near 103 degrees with heat index values mostly between 105-110 degrees. A Heat Advisory remains in effect through this evening. Any convective activity should diminish with the loss of daytime heating during the evening hours. The axis of a mid-level ridge will shift back over the region on Friday which will shut off our rain chances. High temperatures will be in the mid 90s to near 104 degrees. We will meet Heat Advisory criteria once again Friday afternoon with heat index values between 105-110 degrees, so expect the Heat Advisory to be extended through tomorrow at some point today. While heat index values will exceed 110 degrees for a few locations both today and tomorrow, we will fail to meet the two-day criteria for issuing an Excessive Heat Warning outside of a handful of sporadic locations. Nonetheless, it's going to be hot, so ensure you stay hydrated and practice heat safety if spending any time outdoors. Barnes && .LONG TERM... /Issued 314 AM CDT Thu Jun 27 2024/ Update: The current forecast for this weekend through Independence Day is still very much on track (see detailed discussion below). In a nutshell, we will remain hot and humid through next week with a couple of low storm chances Sunday and possibly around July 4th. 79 Previous Discussion: /Friday Through Independence Day/ Mid-level ridging will continue to bake North and Central Texas into early July. The anticyclone will gradually reposition itself from its current location over the Desert Southwest into the Southeast U.S. by the middle of next week. Our 500mb heights will peak during the weekend into early next week as the dome transits the region, the cumulative heat yielding the highest temperatures toward the end of that period (Monday and Tuesday). This will mean clear nights and partly cloudy days as rich Gulf moisture lifts into a cumulus field. DFW's dew point soared to 77F during the daylight hours of this morning, just one degree shy of the record value for June 26. Thankfully, our daily max and min dew points will gradually decrease over the next several days as the heat builds and the mixing depth steadily increases. After many days with 70F+ dew points at peak heating, much of the region will see dew point values mix out into the 60s next week. That's not dry by any means, but max heat index values (while still within Heat Advisory criteria) will be less likely to reach 110 despite the hottest temperatures so far this year. The only decent chance for rain during the period will be Sunday across portions of Northeast Texas. A shortwave will skirt the Canadian border late in the week, sending a cold front deep into the Southern Plains. But the intensity of the ridge will slow its progress and prevent any associated precipitation from impacting areas beyond the low chances within the Ark-La-Tex. By July 4, North and Central Texas will be on the western periphery of the ridge. While heights will still be indicative of subsidence, the sea breeze may activate to our south, and another cold front to our north could disrupt holiday festivities in Oklahoma. Both areas will bear watching for potential impacts within our region. 25 && .AVIATION... /NEW/ /12Z TAFs/ VFR and east to southeast winds below 10 knots will continue. Winds will briefly be out of the southwest for a few hours this morning at KACT, but wind speeds should only be around 4 to 6 knots. Isolated showers and storms may develop across Central Texas and western North Texas this afternoon. This activity should remain well south and west of D10 terminals. While some activity is possible near KACT, the potential is quite low since coverage will be limited. However, we'll keep a mention of VCTS in the TAF for now. Any shower/thunderstorm activity will dissipate near sunset this evening. Barnes && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
