The story of this TAF package will be the approaching cold front. For the I-35 terminals thunderstorms and dropping cigs are expected ahead of the front beginning around 05z. The front should arrive between 08z-10z along I-35 with precipitation transitioning from a thunderstorm treat to rain showers behind the front with a stiff north wind of 15 knots gusting to 25 knots through most of Monday. At DRT chances of showers and thunderstorms begin this afternoon, with thunderstorms possible by 02z tonight.The front should arrive at DRT around 07z with gusty north winds and showers continuing well into Monday. && .PREV DISCUSSION... /ISSUED 526 AM CDT Sun Oct 14 2018/ SHORT TERM (Today through Tuesday)... Early morning surface observations show a frontal boundary located roughly along a Austin to Junction line. Showers continue to develop along this boundary, as well as farther eastward into the Highway 77 corridor and coastal plains. Elsewhere across south central Texas, cloud cover is expanding across the region with temperatures in the 70s ahead of the front with some 60s noted behind the boundary. The above mentioned frontal boundary will weaken and become increasingly diffuse today as southerly flow in the low-levels begins to slowly increase. Meanwhile, an upper level trough over the western U.S. will strengthen and drop southward. As this occurs, we will begin to see an increase in southwest flow aloft. This along with daytime heating should be enough to help initiate some isolated to scattered showers and storms today. With deeper moisture remaining over the coastal plains, we will keep the highest chance for rain across the eastern portion of our forecast area. The hi-res models also show some potential for a few cells to develop over the higher terrain of Mexico this afternoon, then move east toward Val Verde county. Should this activity make it into Val Verde county, we could see a strong to severe storm or two late this afternoon or early evening. The weather pattern will become increasingly active this evening and tonight as a strong cold front moves in from the north. We have followed the hi-res guidance with regards to timing and prefer a faster frontal passage vs. the global models slower timing. Strong frontal forcing will aid in the development of numerous showers and thunderstorms this evening and tonight, especially along and west of the I-35 corridor. Strong to severe thunderstorms along with heavy rainfall will be possible overnight into Monday morning, with the higher chances for severe weather remaining along and west of the I-35 corridor. Damaging winds and large hail will be the main severe weather concerns. Much colder temperatures can also be expected behind the front with many areas seeing falling temperatures throughout the day. High temperatures on Monday will struggle to reach the mid 40s in the Hill Country to near 60 in the coastal plains. Severe weather concerns will fade quickly on Monday behind the front. However, we will continue to see a very high chance for rain, with some locally heavy rainfall possible, mainly in the morning hours. High rain chances along with well below normal temperatures continue into Tuesday as warm air advection above the cold air near the surface results in widespread showers along with a low chance for a few thunderstorms. While we do not expect deep convection resulting in high rainfall rates, any additional moderate rainfall could result in some minor flooding. Rainfall amounts through Tuesday should remain in the 1-2 inch range along and east of I-35. Amounts west of I-35 will be higher, with 2 to 4 inches, with isolated amounts up to 6 inches possible. LONG TERM (Wednesday through Saturday)... The overall weather pattern is not expected to change much through the end of the work week. A deep trough in the mid and upper levels will remain to our west, while surface high pressure continues to funnel cold air southward into Texas. A reinforcing shot of cooler air looks to arrive Saturday as the operational GFS and ECMWF begin to show some disagreement with the mid and upper level flow pattern. We will keep a chance of rain in the forecast given continued warm air advection in the mid-levels. Temperatures will also remain below normal through the remainder of the forecast with cold air advection in the low-levels and a continued chance for rain. && .PRELIMINARY POINT TEMPS/POPS...
