/Issued 432 AM CDT Fri May 17 2024/ Update: Convection overnight could not overcome the stable air currently in place across North and Central Texas. We could still see additional showers and storms later today associated with the exiting shortwave. The best storm chances will remain near the Red River. We will go ahead and cancel the Flood Watch that was in effect until 7 AM and leave the remainder of the forecast largely unchanged outside of some minor hourly grid adjustments. 79 Previous Discussion: /Tonight through Friday Night/ After a brief reprieve from showers and thunderstorms this evening, additional showers and a few thunderstorms will continue to move in from the west overnight. This activity will be moving into relatively stable air currently across North and Central Texas. Therefore, we don`t anticipate much in the way of severe weather, but we can`t rule out a strong storm with gusty winds or small hail. We will maintain the Flood Watch through the night, but most of the rain associated with the activity overnight will likely not cause too many additional flooding problems. Extensive clouds and patchy fog overnight will keep temperatures generally in the 60s. The only exception will be across the far west where clouds will partially clear, allowing for lows to fall into the upper 50s. Friday will be a much less active day than today with most locations not seeing any additional rainfall. However, we will maintain some low chance PoPs (20%-40%) generally north of I-20 due to the passage of a trailing piece of shortwave energy. Although clouds will linger for part of the day Friday, there will still be some afternoon sun, allowing temperatures to warm into the upper 70s to lower 80s. Temperatures will steadily fall after sunset Friday under a mostly clear sky. The clearing sky and wet ground will result in patchy fog, especially overnight through Saturday morning. 79

&& .LONG TERM... /Issued 359 AM CDT Fri May 17 2024/ /This Weekend Through Next Week/ After our period of unsettled weather, a rain-free interlude will begin this weekend with temperatures and humidity steadily increasing into early next week. A cold front may approach during the middle of the upcoming week, increasing cloud cover and reintroducing rain chances, but seasonally warm temperatures will prevail. The storm system that doused the region yesterday will finally pass east of our meridian Friday night, being replaced by ridging aloft. Positive mid-level height anomalies will prevail into next week, pushing daytime temperatures into the 90s. Combined with rich Gulf moisture, this weekend will remind us that the Texas summer is right around the corner. The heat and humidity will culminate on Tuesday when heat index values will top 100 in many locations. The rather strong early-season subtropical ridging over Mexico that will nose into the Lone Star State will keep the spring storm tracks to our north. However, a midweek shortwave emerging from the Rockies and transiting the Central Plains will manage to deamplify the ridge a bit, potentially sending a cold front in our direction. There is little agreement as to how far equatorward the boundary will penetrate, the eventual evolution perhaps governed by its associated convection. In any event, its proximity should by sufficient to return rain/storm chances to the forecast. However, the current forecast will maintain the plurality of southerly winds and seasonally warm temperatures throughout the upcoming workweek. 25 && .AVIATION...

/NEW/ /12Z TAFs/ Stratus has finally developed across portions of North and Central Texas early this morning along with patchy fog. Recent guidance is optimistic, keeping ceilings above 1000 ft, and in many cases above 3000 ft. We are inclined to believe that a bit of daytime heating through the near saturated boundary layer will result in temporary MVFR ceilings at all TAF sites, likely in the 13Z to 16Z time frame. Some visibility restrictions between 3 and 5 miles are also possible. By late morning, any low ceilings should lift above 3000 ft, eventually scattering during the afternoon. VFR conditions are expected this evening but some visibility restrictions due to patchy mist and fog will be possible again early Saturday morning, especially in Waco. A few showers and thunderstorms will be possible across portions of North and East Texas this afternoon and evening. Coverage will be too limited to include in this TAF package. A light west to northwest wind will prevail for much of the day, becoming southwest to south late in the afternoon. Wind speeds will stay below 10 knots through Saturday morning. 79
