Area Forecast Discussion National Weather Service Fort Worth TX 657 PM CDT Fri Apr 30 2021 ...New Short Term, Aviation... .SHORT TERM... /NEW/ /Tonight through Saturday Night/ Water vapor imagery shows the slow moving upper low still to the west of the region with extensive cloud cover over most of the state. Showers and thunderstorms are ongoing across the Hill Country and while we have a little lull in the precipitation across North Texas, rain chances will increase again later tonight into Saturday. Model guidance suggests another wave of ascent will spread into North Texas on the east side of the upper low later tonight. Given the moist profile in place, we should see an uptick in precipitation around midnight. We'll maintain high PoPs throughout the period until this upper low moves off to the east, but it won't rain in all areas all the time. Additional rainfall amounts will be highest south of I-20 into Central Texas where some minor flooding could occur. With the upper trough beginning to move east on Saturday, there will be a low threat for severe weather mainly south of I-20. This will be dependent upon the amount of instability we'll have to work with given the extensive cloud cover, but low and mid level wind fields will strengthen given the proximity to the upper low. This may support a low end damaging wind or tornado threat in the strongest storms. Rain chances will taper off from west to east late Saturday night into Sunday. Dunn && .LONG TERM... /Issued 305 PM CDT Fri Apr 30 2021/ /Saturday Night Onward/ Showers and storms will likely be ongoing as we begin Saturday night, some of which could be strong to severe. In addition, there will be a heavy rainfall threat that may lead to minor flooding, especially south of I-20. The system responsible for this round of precipitation will be emerging out of the Mexican high terrain, moving to the northeast through tomorrow. With strong southerly flow induced by the system, plenty of moisture will be working its way northward into North and Central Texas. Moisture, large scale forcing for ascent and a warm front moving northward will lead to fairly high coverage of precipitation. There is still a bit of uncertainty in just how much destabilization will take place tomorrow afternoon, which would then have an effect on the overnight precipitation. At this time, the severe weather potential isn't overly large, but we'll continue to monitor the high-resolution guidance through the rest of today and tonight in case shear/instability values increase. With the system departing to the northeast, precipitation chances will be decreasing from west to east as westerly winds and drier air move in. By Sunday afternoon, winds across the region will become southwesterly, bumping our temperatures to near normal readings. Widespread 70s to mid 80s can be expected. The next upper level trough will be approaching the region on Monday, inducing southerly surface flow throughout the region. The development of a surface low across Oklahoma ahead of southeastward advancing front will overspread a fairly stout capping inversion throughout North and Central Texas. This capping inversion will likely keep widespread precipitation from developing much of the day. We'll need to monitor the area immediately ahead of the front as concentrated forcing for ascent may help a surface parcel tap into the 1500+ J/kg of energy above the EML. A redevelopment of showers and storms looks possible Tuesday afternoon, mainly across Central and East Texas. The location and amount of rainfall will depend on whether Monday's front stalls in our area, or closer to the Gulf Coast. Either way, precipitation probabilities were increased across the Brazos Valley Tuesday afternoon to account for this potential. A building ridge across West Texas will help push all rain chances well east of our region by early Wednesday morning, leaving behind a dry forecast the rest of the week. Highs each day will be a few degrees below average as northerly winds stick around through Thursday. By Friday of next week, southerly winds will once again return, leading to a gradual warm up as we go through next weekend. Hernandez && .AVIATION... /NEW/ /00Z TAFs/ Widespread MVFR and IFR conditions are expected to continue through the overnight hours into most of Saturday as our slow moving upper low will make only some eastward progress over the next 24 hours. We'll have periodic showers/VCTS in through the period with the main timing expected later tonight and again tomorrow afternoon/late evening. Outside of the areas of rain/storms, cigs are likely to fall below 1000 ft late this evening and remain there into midday Saturday. Brief MVFR may occur during the day before falling back to IFR Saturday evening. Dunn && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
