623 PM CST Sun Feb 19 2023 ...New Short Term, Aviation... .SHORT TERM... /NEW/ /Tonight and Monday/ A second night of southerly flow should result in a more inland surge of nocturnal stratus, but the strongly veered flow should keep the bulk of the low clouds southeast of our area. However, our Brazos Valley counties may experience this deck and/or the associated patchy fog. The rest of the region will maintain a dense plume of mid/high clouds from the Pacific, which should keep Monday`s high temperatures only 15 to 20 degrees above normal. Many locations will reach 80F Monday afternoon with gusty mountain cedar winds. 25 && .LONG TERM... /Issued 311 PM CST Sun Feb 19 2023/ /Monday night through Next Weekend/ This week`s headlines include the unseasonably warm conditions through the first half of the week, mid-week rain chances, followed by cooler weather Thursday and Friday. Warm and breezy conditions are expected on Tuesday with temperatures 10-20 degrees above normal for mid February. Most locations will see highs in the 80s with south/southwest winds 10-20 mph gusting to 25 mph. These winds will continue to bring moisture into our area with mostly cloudy skies by Tuesday night. The combination of moisture and clouds will keep overnight lows in the 60s area wide. As advertised over the last few days, an active weather period will take place Wednesday as an upper-level trough moves across our state and a Pacific front moves eastward. Scattered showers and thunderstorms will begin to develop late Tuesday night into Wednesday morning as large scale ascent overspreads the region. Coverage of precipitation will increase during the day on Wednesday as the surface boundary brings additional lift over a moist airmass. Forecast sounding show decent mid-level lapse rates which will support the development of healthy updrafts for organized storms. Further destabilization during the afternoon hours may support the potential for strong/severe storms (mainly across the northeast), but at this time it appears most of the activity will be east of our area during this period. Continue to monitor the forecast over the next few days as details get refined. Otherwise, rainfall totals are expected to stay between 0.25-0.50 inch west of I-35 and 0.50-1.0 inch east of I-35. We can`t rule out some locally heavy rain, but the potential is low due to the progressive nature of this system. It is important to mention that some locations across the west may miss out any appreciable rainfall with this system. If they do, fire weather concerns will increase due to the dry and gusty conditions behind the front Wednesday afternoon. A shallow cold front is expected to arrive late Thursday with cooler weather behind it. Forecast high will go from the 70s/80s on Wednesday to 50s/60s on Friday. Breezy northerly winds are also anticipated to follow Thursday`s front. This front will linger somewhere near the Texas Coast and retract northward as a warm front sometime Friday and Saturday. This will trigger a few showers as early as Friday, but the best chances appears to be on Saturday and perhaps Sunday. Sanchez && .AVIATION... /NEW/ /00Z TAFs/ Concerns: virga-induced turbulence today, low-level wind shear potential tonight, and minor crosswind issues Monday. The lower reaches of our subtropical plume extend into the mid levels where virga has again produced some sub-cloud turbulence. This should be largely above 10kft AGL and not an impact to arriving/departing aircraft at the terminals. Guidance is keying on the 40-45kt wind potential near or below 1kft AGL overnight and into the daylight hours of Monday morning. However, unlike Sunday morning, steadier/gustier surface winds should assure a greater depth of veering/increasing winds. As this scenario is unlikely to meet criteria, LLWS will not be included with this TAF package, but arriving aircraft Monday morning (particularly GA) should be aware of these impacts on approach. Stratus will surge into Southeast Texas late tonight, but the strongly veered flow should keep this generally MVFR deck southeast of Waco. Westerly 925mb winds may reach 50kts Monday morning, some of the momentum from which will veer and increase surface winds. Veering to 230 with sustained speeds potentially topping 20kts, this would introduce some minor crosswind issues at DAL and on the diagonals at DFW. 25 && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
