760 FXUS64 KFWD 042032 AFDFWD Area Forecast Discussion National Weather Service Fort Worth TX 332 PM CDT Thu Jul 4 2024 ...New Long Term... .SHORT TERM... /Issued 1243 PM CDT Thu Jul 4 2024/ /This Afternoon though Friday Night/ Hot and humid conditions continue this afternoon but changes are on the way. Temperatures at this hour have climbed into the lower 90s with heat indices just above 100 degrees. We`ll top out with actual air temperatures just above 100 later this afternoon. Farther to our north, a cold front is draped across northern Oklahoma and will continue to slide south through the afternoon as stronger ridging shifts eastward and a shortwave digs through the Central Plains. Scattered thunderstorms will develop later this afternoon to our north and drift toward the Red River after dark. The consensus among the short term guidance is that robust convection to our north will send an outflow boundary southward after midnight with the main line of storms weakening. Renewed convective development will occur along this boundary and the actual cold front on Friday morning mainly north of I-20. This activity should drift south through the I-20 corridor through midday with additional storms developing farther south later in the day. We will also be watching the low potential that thunderstorms don`t actually weaken overnight tonight and drift southward, entering North Texas after midnight and continuing through the early morning hours. Given this is the lower probability scenario, we`ve raised PoPs on Friday to 40-60% across the I-20 corridor with PoPs shifting southward through the day. Most of the shower and thunderstorm activity will be diurnally driven with a decrease in activity Friday evening and night. Along with the increased rain chances and cloud cover, temperatures will be considerably cooler than the last several days with highs topping out in the lower 90s in most locations. Some areas closer to the Red River may remain in the 80s. A period of cooler and more unsettled weather looks to continue into early next week. Dunn && .LONG TERM... /NEW/ /Saturday Through Next Week/ After two full weeks dominated by oppressive ridging, a significant pattern shift is underway. Texas will spend the next several days underneath a col between a pair of ridges, one in the West and another over the Southeast. This will mean increased cloud cover and rain chances with below normal daytime temperatures. This extended period of unsettled weather will continue throughout the upcoming week, during which we may also see impacts from a tropical system. The aforementioned frontal boundary may linger on Saturday, a weak disturbance aloft aiding in renewed development throughout the daylight hours, more likely south of the I-20 corridor. With the weakness aloft, another frontal system will dive into the Central Plains this weekend. Although well north of us, its associated surface low will return southerly winds to North and Central Texas on Sunday, dissolving what`s left of our aging front. This warm advection and increasing insolation will push daytime temperatures back closer to normal values on Sunday. With little inhibition, a few afternoon showers and storms may develop Sunday afternoon within the deeper moisture across East Texas. The more organized convection will be associated with the frontal boundary in the Central Plains, the resulting MCS making a surge at North Texas late Sunday night into Monday morning. Despite seasonally tepid inflow, guidance is still convinced this will occur. If so, it could bring widespread rain to the region on Monday, which would then be a remarkably mild day. Hurricane Beryl will spend the weekend crossing the Gulf of Mexico along the northern edge of the Bay of Campeche. With weak steering flow, there remains appropriate spread among ensemble members. But with the West Coast ridging extended deep into the tropics, it`s becoming increasingly likely that our col will be the favored direction. Despite reasonable uncertainty at this time scale, guidance is coming into better agreement with a landfall near the mouth of the Rio Grande Monday morning. Beryl`s remnants would then spread northward, bringing enhanced rain chances to North and Central Texas Tuesday and Wednesday. It`s too early to discuss amounts or locations, but this should further diminish our negative mid-level height anomalies, maintaining our unseasonally mild/wet pattern. 25 && .AVIATION... /Issued 1243 PM CDT Thu Jul 4 2024/ /18Z TAFs/ VFR will prevail this afternoon and evening with south winds around 10 kt but a cold front will approach the region later tonight. Thunderstorms should develop along a cold front to the north of the D10 airspace later this afternoon with most of the activity remaining tied to the frontal boundary. This front will slide southward into North Texas on Friday with scattered showers/storms becoming more likely Friday morning through midday. A wind shift to the north-northeast will accompany the frontal boundary. Outside of any convective areas, VFR will prevail. Dunn && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
