Area Forecast Discussion National Weather Service Fort Worth TX 557 AM CST Sun Feb 11 2018 .AVIATION... /12Z TAFS/ MVFR conditions generally prevail across North Texas this morning with north winds 15-20 kt. The main concern through the next several hours will be the potential for some light freezing rain or sleet as a band of mid level forcing spreads across North Texas. Area radar imagery already shows scattered elevated convection from near Fort Worth extending back southwest to San Angelo. This is streaming northeast across the area and this trend should continue through midday. There is some very dry air beneath the cloud deck where the precipitation is occurring, so some evaporation is occurring before some of this makes it to the ground. We'll keep a TEMPO for some -FZRAPL through the late morning hours, although no significant accumulations are expected. Some very light accumulations of ice or sleet can be expected through late morning before temperatures warm above freezing during the early afternoon hours. Cigs should improve to VFR by midday with continued lifting through the afternoon hours. At Waco, similar trends with respect to cigs can be expected although now it is looking more likely that the heavier precipitation will remain to the north. We've removed the freezing rain and sleet mention from the Waco TAF. All precipitation will come to an end by early afternoon with VFR conditions prevailing this evening and tonight. Dunn && .SHORT TERM... /Issued 331 AM CST Sun Feb 11 2018/ /Today and Tonight/ A reinforcing shot of colder air moved into North Texas shortly after midnight accompanied by stronger north winds and temperatures falling into the lower 20s. Most of North and Central Texas is now below freezing with the exception of our far southern counties, but these areas too will fall to below freezing over the next few hours. Extensive cloud cover persists across the region as warm moist air lifts up and over the colder surface airmass. Our main concern for today will be the potential for some light freezing rain and sleet as mid level forcing for ascent spreads across North Texas. The air above the frontal layer remains fairly dry, but low and mid level water vapor imagery shows some increased moisture streaming in across Northern Mexico into the Big Bend region and into west-central Texas this morning. Later this morning, as the main trough axis swings into the Texas Panhandle, isentropic ascent in the 800-600mb layer will really increase across Central and North Texas. While the forcing is quite strong, moisture availability will remain marginal at best. Normally, this wouldn't be of any significant concern, however given the strength of the forcing within an area of steep lapse rates (>7.5 C/km), parcels that do saturate can quickly become buoyant resulting in convection. The strong ascent tends to find the moisture if there is any available. Over the last hour, we have seen some indication of this occurring to the west of San Angelo where spotty convection is now apparent on radar. As this forcing spreads eastward, it is likely that there will be at least some scattered convective cells that develop across parts of North Texas. That being the case, precipitation type should either be freezing rain or sleet given the extensive warm nose above the surface. If the convection is strong enough, then sleet would probably be favored, but if it generally lighter, then the warm nose would likely melt everything with only limited time for refreezing. This would support more of a freezing rain scenario given the surface temperatures in the upper 20s. Either way, there is some potential for icing especially on bridges and overpasses. Any heavier bursts of rain/sleet could cause some localized higher impacts. Concerning the advisory...we have decided to trim a good chunk off of the Winter Weather Advisory with this issuance. Our northwest and Red River counties will likely miss out on any precipitation given that deeper colder and drier air is in place and the best forcing should spread to the south. In our northeast counties, some light freezing drizzle earlier yesterday evening has come to an end and visibilities have improved with drier air moving in. Any additional precipitation later today should occur as temperatures rise to or just above freezing. This should mitigate any impacts in this area. We'll keep the advisory from the Metroplex southwest to Eastland/Mills/Bell counties. All of this precipitation should come to an end later this afternoon with skies clearing this evening. It will be another cold night with temperatures in the lower 20s northwest to lower 30s in the southeast. Dunn && .LONG TERM... /Issued 331 AM CST Sun Feb 11 2018/ /Monday Onward/ A cool and dry Monday will be in store as skies clear temporarily while winds come around to the east and southeast. The glimpse of sunshine will be short-lived, however, as moisture will be quick to return late Monday into Tuesday. This resultant blanket of stratus should keep temperatures on the warmer side Monday night with most areas holding above freezing. The warmer start to Tuesday and increased southerly flow/warm advection will cause temperatures to climb into the 50s or low 60s during the day despite cloudy skies. Some light rain or drizzle due to low-level ascent may also occur mostly east of I-35 throughout the day. The sun will remain scarce through the middle of the week as rich low-level moisture and resultant low clouds continue to stream northward. Some higher rain chances will occur on Tuesday night into Wednesday as ascent from low-level warm advection increases. The GFS and ECMWF have flip-flopped from yesterday's solution, and now the ECMWF is the wetter of the models through this time period. Have maintained PoPs around 30-40% and hopefully guidance will come into better agreement on rainfall potential in the next couple of days. In addition, because of the increased warm advection, temperatures will be several degrees higher on Wednesday. Highs in the 60s or low 70s will be likely as dewpoints climb into the 50s and low 60s. This will also mean a warm and humid Wednesday night with low temperatures only falling into the low 60s or upper 50s. Thursday should be the warmest day of the week prior to the arrival of another cold front late Thursday night or Friday morning. Depending on the front's arrival time, some pre-frontal warming could see high temperatures climb to 75-80 degrees Thursday afternoon. Rain chances will also accompany this front and they will be on the increase heading into Friday and through the weekend. However, there is still much disagreement on handling the shortwave that will be responsible for these conditions. The ECMWF maintains a much more open wave while the GFS keeps the low cutoff for an extra day. However, both of these solutions are trending more progressive over the past couple of runs. As a result, will go with some 30-50% PoPs Friday into the weekend, which at this point looks like a cold rain with temperatures mostly in the 40s. -Stalley && .PRELIMINARY POINT TEMPS/POPS...
