Current Doppler radar data and surface observations are detecting light rain over a few spots across the Rio Grande and Coastal Plains. This activity is elevated in nature and very little of it is reaching the ground. It looks like a lot of precipitation but it is not. This light showery activity continues through late this afternoon mainly over the western half of South Central Texas with a mix of partly sunny to cloudy skies. There is even sunny skies over the Hill Country as of this writing with temperatures in the low to mid 60s and upper 50s to low 60s where clouds are dominating.
A cloudy night is in store for this evening into Tuesday morning with overnight lows ranging from the mid and upper 40s to low 50s a long the Rio Grande.
Tuesday starts cloudy and remains cloudy and cool with highs in the 60s. No rain expected through the period across the local area with the exception of a few sprinkles (opted not to show this probability due to low confidence)across the northwest part of Val Verde County.
Tuesday's night temperatures ranging from the mid 40s to the mid 50s along the Rio Grande.

The upper level low/trough will remain to our west for one more day on Wednesday before finally ejecting east across the southern Plains late Wednesday into Thursday. As it does so, there should be enough upper level lift and instability to overcome weak surface instability and a capping inversion, resulting in the development of scattered showers and thunderstorms across the area overnight into Thursday morning. As convection initially develops, a couple of the stronger, discrete cells may be capable of producing isolated large hail, and SPC has a Level 1/5 risk in place across much of the area to cover this threat.
The frontal boundary associated with this system will be pretty weak since the parent low/trough has spent so much time sitting out west, though dry, northwesterly flow is expected during the day Thursday across western portions of the area which could lead to an elevated fire weather threat. Otherwise, temperatures will warm to slightly above normal levels Thursday into the weekend as northwesterly flow sets up aloft behind the departing trough. This should also result in dry conditions until at least Sunday night when a longwave trough will begin to move in from the west coast. An initial wave from this system may bring some shower development across northern portions of the area Sunday night into Monday, with the best forcing appearing to remain further north of south-central Texas at this time. While beyond the current 7-day forecast, additional precipitation chances are expected closer to mid-week next week as the main system begins to push into the region.

Some -SHRA over the Hill Country to across and east of portions of I-35 corridor will gradually move east of our area this evening. Have VCSH mention at KAUS through 02Z. VFR flying conditions prevail tonight through Tuesday evening. There may be some lowering of clouds Tuesday afternoon into evening, however they will remain above FL035. Northeasterly winds 5 to 12 KTs become light at less than 5 KTs overnight, then southeasterly at 6 to 14 KTs on Tuesday.
