...New SHORT TERM, LONG TER
.SHORT TERM... (Today through Thursday) Issued at 424am CDT Wednesday Mar 29 2023
A weak mid level short wave trough moving across south Texas this morning will interact with an elevated moist layer to keep a chance of showers over the coastal plains this morning into early afternoon. Latest HRRR/HREF models show any sufficient elevated instability will be to the south of the area today, so did not include the mention of thunder in the forecast. Weak surface high pressure ridge will remain over the area today. With cloud cover in place, highs will be 7-10 degrees below normal over the coastal plains and near 15 degrees below normal for the LRD area.
Low level flow will veer to southeast and increase to 25-30 knots tonight. With weak low level warm air advection and isentropic lift, isolated showers are expected to form over the Brush Country this evening and across the inland areas overnight.
Low pressure will deepen over the southern high plains Thursday as a mid level trough moves across the central Rockies. The frontal boundary will move north of the region Thursday as a warm front. South-southeast winds will become breezy to windy over the coastal plains Thursday afternoon. Isolated streamer showers will be possible mainly across the northern counties Thursday. Mid level inversion will be strong to inhibit convection. Highs will be warmer Thursday with readings near normal.
With northeast winds around 20 knots over the Gulf waters and adequate swells with period of 7 seconds, the rip current risk will increase to high for today. The winds will be a little weaker as they veer to east-southeast this evening and then southeast on Thursday. The risk for rip currents will be moderate tonight into Thursday.
(Thursday night through next Tuesday) Issued at 424am CDT Wednesday Mar 29 2023
Warm temperatures will continue through the remainder of the week and into the weekend as southeast to southerly flow prevails over South Texas. Winds are expected to strengthen as the pressure gradient tightens over the coastal plains Friday.
Another mid-upper level shortwave trough on Saturday will send a second frontal boundary through South Texas. Models show this boundary stalling across the area, and with PWAT (Precipitable Water) values of 1.5-1.7", this should allow for isolated showers and thunderstorms. Best chances of precipitation for Saturday will be across the western and northern CWA. Further support will be provided by the RRQ of an upper-level jet along with low-level convergence as the trough lifts north.
The work week next week is expected to start off with a ridging pattern; however, embedded shortwaves will bring a slight chance of showers to the western CWA. Otherwise, temperatures will be on the rise again, and highs are projected to reach into the triple digits for locations in the Rio Grande Plains and Brush Country early next week.
Model guidance continues to show an increase in swell heigheights Friday which could lead to a moderate to high risk of rip currents.
Issued at 424am CDT Wednesday Mar 29 2023
Moderate to strong northeast winds will continue over the Gulf waters today with a Small Craft Advisory in effect until 4pm today for the offshore waters. The winds will become moderate easterly tonight and then southeast Thursday as a warm front moves north through the area with SCEC conditions (Small Craft Should Exercise Caution) over the offshore waters. Scattered showers are expected today with isolated showers possible tonight into Thursday. Winds may approach SCA (Small Craft Advisory) over the southern bays Thursday afternoon.
A moderate to strong onshore flow is expected Thursday night into Friday. A weak easterly flow will develop Saturday morning as a weak front moves into south Texas. Winds will become weak to moderate out of the southeast on Sunday.
