NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Feb 24, 5:47 AM CST, 4 hours 13 minutes earlier.
Area Forecast Discussion National Weather Service Fort Worth TX 547 AM CST Sat Feb 24 2018 .AVIATION... The primary aviation weather concerns this morning will be in the first 6 hours of the TAF cycle with periods of rain and thunderstorms and LIFR ceilings and visibilities at all sites. Elevated thunderstorms were ongoing across the western Metroplex TAF sites as of 12Z TAF issuance. These storms will reach DAL and Waco between 12Z and 13Z. A more organized line of storms (currently developing west of a Bowie to Eastland line)will move quickly across all TAF sites a bit later this morning. These storms will have a potential to produce some large hail and gusty winds. The only good news is that the storms will be fast moving and should clear all TAF sites by midday with rapidly improving ceilings and visibilities during the afternoon. The only issue this afternoon at the terminals will be a strong and gusty west wind between 13 and 17 knots which may cause some crosswind issues on north/south runways. Wind speeds will decrease around sunset and winds will become more northerly. VFR conditions are expected this evening and overnight with winds generally less than 10 knots. There will be a potential for some fog overnight due to clearing skies, light winds and a moist ground, but wind speeds should stay up enough to prevent dense fog from developing. 79 && .SHORT TERM... /Issued 328 AM CST Sat Feb 24 2018/ /Today and Tonight/ A surface warm front was analyzed snaking its way from near a Paris to Sulphur Springs to Mexia to Temple line early this morning, delineated more-or-less by the 60 degree isodrosotherm. To the north and west of this feature, winds remain light and out of the northwest with a completely saturated airmass in the lowest two thousand feet or so. This is resulting in a combination of widespread fog and drizzle across most of North and Central Texas. Based on current observations and short-term model guidance, we have elected to expand the Dense Fog Advisory a bit farther to the north and west. We may need to add the remaining three northwestern counties (Young, Jack, and Montague) at some point depending on observation trends. Radar mosaic imagery is already showing the development of another wave of showers and embedded thunderstorms just to our south and west. This activity seems to be associated with strong warm advection in the 850-700 mb layer ahead of an intense vort max barreling east of the Four Corners region at this hour. The TTWRF and most recent 06z 3-km NAM seem to be handling this ongoing activity the best, and show a continued expansion of thunderstorm coverage across roughly the western half of the CWA through sunrise. Recent data from the SPC mesoanalysis shows the MUCAPE values are increasing past 1000 J/kg at this hour (above the frontal inversion) aided by very steep mid-level lapse rates which are approaching 7.5 to 8.5 C/km in spots. In addition, effective deep layer shear values are increasing as a 130+ kt jet streak is starting to impinge on our region. These values are increasing past 55-60 kts across the Concho Valley. This parameter space will easily support elevated supercells this morning, developing perhaps as early as 5-6 AM as this activity continues to intensify to our south and west. Large hail, perhaps to the size of golfballs, will be the main threat with this initial activity considering the steep mid-level lapse rates and very strong shear. I can't rule out some stronger winds working their way to the surface this morning, but the temperature inversion remains quite robust, and it will take a good deal of momentum transfer to realize strong-severe wind gusts here. We will need to keep an eye on our south and eastern counties by mid-morning and onwards as this initial wave of thunderstorms starts to move towards the warm front. Storms may attempt to become surface-based at this point roughly south and east of a Sulphur Springs to Terrell to Temple line. As this occurs, the threat for damaging wind gusts and even a few tornadoes will ramp up. One mitigating factor here will be the time of day, as this morning wave will not give much, if any, time for robust destabilization out east. Still, an extremely impressive low-level wind field continues to drive mid and upper 60s dewpoints into our southeastern counties at this hour, and long, clockwise-curving hodographs with 0-1 km shear values pushing 35-40 kts are causes for concern. An additional area of showers and storms may actually develop behind this initial warm-advection-induced wave towards the mid- late morning hours across our NW as mid-level heights really begin to fall in advance of the incoming shortwave. How much the atmosphere is "worked-over" from the morning activity is in question, but this secondary activity will pose an additional large hail risk near and west of the I-35 corridor into the early afternoon. This wave of convection should tend to become more linear with time and spread east of I-35/35E after about 12-1 PM or so. As this activity presses east during the afternoon and early-evening, the severe threat will depend on how much the atmosphere has been contaminated by the morning wave. Given the thermodynamic-shear space, all modes of severe weather will remain possible, however. We have set the flood watch to expire at noon today for the two columns of counties west of I-35 as all the heavy precipitation should be east by then, with the watch continuing through 4 PM to the east. While this activity today will move at a good clip, very heavy rainfall rates will be possible, leading to additional instances of flooding. Breezy westerly winds will materialize this afternoon as convection clears the I-35 corridor, driving much drier air into the region. In fact, many of us from the Metroplex and points west will actually see the sun for the first time in many days! Relative humidity values will fall into the 20-30 percent range out west. This combination would normally result in an elevated fire weather threat, but with the recent rainfall, the fire weather potential appears low this afternoon. As skies clear tonight, some radiation fog is possible given the recent rains, but the signal was not strong enough to warrant an addition of fog to the overnight forecast. Carlaw && .LONG TERM... /Issued 328 AM CST Sat Feb 24 2018/ /Sunday through Friday/ A few showers may redevelop across the southern portions of the forecast area on Sunday as a shortwave moves east out of the Central Rockies and lifts moisture over the stalled cold front located near the the Texas coast. Precip chances will end Sunday evening as the shortwave moves to the east. Brief ridging aloft and dry air in the low levels of the atmosphere will result in a mostly sunny and mild day on Monday with highs in the 60s and lower 70s. The ridge axis will move east of the region Monday night while another low pressure system strengthens in the west. As a result, low level moisture and large scale upward vertical motion will both increase Tuesday through Wednesday, resulting in a chance of showers and thunderstorms. The upper trough should move east of the state Wednesday night and allow a cold front to push into the region through Thursday, bringing drier and cooler weather Thursday and Friday. There are some differences between the medium range models regarding the speed of the upper trough and cold front, so for now we will keep only chance PoPs in the forecast. Temperatures Tuesday through Friday will be near or above seasonal normals with highs mainly in the 60s and lows generally in the 40s and lower 50s. 79 && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.

Dense fog will be possible across most of North and Central Texas through 9 AM. Visibility will be reduced to less than 1/2 mile in many locations. Thunderstorms are expected across the entire region today. Locations along and west of the I-35 corridor will have the best chance of seeing some severe storms through mid morning with large hail being the primary hazard. The severe weather threat will continue through the afternoon, with the most favored area shifting east of the I-35 corridor. Large hail, damaging winds and a few tornadoes will all be possible. In addition, heavy rain will aggravate any ongoing flooding. All thunderstorms will move southeast of the region this evening. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Thunderstorm chances will return to all of North and Central Texas Tuesday through Wednesday night. A few strong storms will be possible. .SPOTTER INFORMATION STATEMENT... Spotter activation is possible today. The most likely time for activation west of the I-35 corridor will be before noon with the activation possible elsewhere generally from late morning through the afternoon.
