SHORT TERM (Today through Monday).
A weak mid level disturbance has been producing isolated elevated showers and patchy sprinkles this afternoon across northern and eastern areas of the CWA. This activity should continue to weaken and move east through the remainder of the afternoon, with a lull in precip expected by this evening through most of tonight.
However, an upper level low currently across Arizona is forecast to dig southeast into Mexico tonight and then open and move east through the Big Bend and into South-Central Texas on Monday. Elevated convection could develop during the early morning hours across Val Verde County, spreading northeast through the Hill Country during the day as the energy gets stretched southwest to northeast. the GFS and ECMWF aren't too impressive with the mid- level moisture, however they under achieved with today's moisture and resulting elevated showers. We have went higher than NBM PoPs from Val Verde through the Rio Grande, forecasting isolated to widely scattered showers from the Rio Grande through the Hill Country, similar to several HREF members. Can't completely rule out an isolated thunderstorm or two through this region. Farther east, there could be some sprinkles or isolated showers into the I-35 corridor Monday afternoon and early evening, however we have left mention out for now.
Cool temperatures are forecast tonight, dipping into the mid 40s to low 50s. Slightly warmer tomorrow, into the low to mid 70s for most areas as a weak east to southeast low level flow resumes.
LONG TERM (Monday Night through Saturday).
A mid to upper level short wave moving across the Central and Southern Plains into the Middle Mississippi Valley on Tuesday and Tuesday night sends a cold front across South Central Texas. The cold front is forecast to push across the area early to mid afternoon and exit late afternoon. Behind the frontal boundary strong northerly winds are expected for the afternoon into Tuesday night as a strong surface high pressure builds across the Southern Plains. Northerly winds of 15 to 25 mph and gusts up to 30 mph are expected. Before the cool air spreads across the area on Tuesday night, highs are forecast to range from the upper 70s across the Hill Country to mid 80s across the southwest counties. As the night progresses, the dry and cool air takes over and provides an early feels-like fall night with temperatures in the lower 40s and 50s. Can't rule out some 30s over few spots across the Hill Country.
By Wednesday, temperatures are forecast to range from the mid to upper 60s across the Hill Country to mid 70s elsewhere. Late Wednesday night into Thursday, the surface high pressure pushes to the east and allows the return of southerly flow across the area. Increased gulf moisture pushes to the north and into the lower Rio Grande, where a few showers are expected early Thursday morning. The increased moisture and instability will lead to more shower activity during the day on Thursday through Friday as an upper level system moves over Baja California and then northern Mexico for the latter part of the work week.
This setup has the potential for strong to severe thunderstorm activity especially on Friday. At this time is hard to pin point those areas to possibly be affected as model guidance differ with the passage of the upper level disturbance and a frontal boundary over the weekend. Stay tuned for updates as the event gets closer.
