000 FXUS64 KHGX 090307 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 907 PM CST Thu Mar 8 2018 .DISCUSSION... Another quiet and cool weather night is in store for Southeast Texas. Just making a couple insignificant changes to the grids on the evening update. 42 && .PREV DISCUSSION... /ISSUED 615 PM CST Thu Mar 8 2018/ AVIATION... VFR. Cirrus continues through the overnight hours with a weakening southeasterly wind. A tighter statewide onshore pressure gradient will strengthen Friday`s southerly winds with lower level saturation at around 4-5 k ft thickening and lowering decks to low end VFR by the early evening hours. 31 PREV DISCUSSION... /ISSUED 352 PM CST Thu Mar 8 2018/ DISCUSSION... We are aware of the smoky conditions across parts of the metro area and southeast Texas today, but have several conflicting reports as to where its is actually coming from. Satellite and radar are not showing any signals either as they can sometimes help in these situations. Based on steering flow, it`s likely from somewhere east of the area. Good news is that wind directions will continue veering to the southeast tonight as high pressure moves away, so theoretically we should see some improvement IF that was indeed the origin. Otherwise, look for a benign wx night with just a slow increase in llvl moisture returning from the Gulf. We may start seeing some weak isolated waa shra pop up on radar throughout the day Friday. Speed max embedded in the upper jet will be making its way around the ridge and into into south cntl Tx Fri evening and night putting us in the LFQ for a time period. There have been some run-to-run model consistency issues as to whether we`ll see an enhancement of shra/tstm coverage thru the night into Sat morning. This set of model runs is drier than the past several. Texas Tech WRF isn`t excited whatsoever. We lowered POPs a touch, but fcst confidence isn`t there to make drastic changes. Though there`s some instability, don`t have a big concern for strong/severe tstms attm. As llvl flow veers to the sw thru the day Sat, moisture availability will diminish and capping comes into play ahead of the cold front that`ll be pushing thru late Sat night and Sunday morning. That should limit precip chances ahead of the front. Main issue will be strong winds in the wake of the front with 40kt 925mb winds noted. ECMWF is showing a disturbance riding down the nw flow aloft during the day Sunday. Other than virga, one would think that column moisture would be too low for much in the way of precip, but POPs will definitely need to be upped if the ECMWF soln holds in future runs. Low and mid level ridging will prevail into midweek keeping dry, but slightly below normal conditions in place. Onshore flow resumes during the second half of spring break along with a gradual warming trend. 47 MARINE... Winds are continuing to slowly weaken/shift to the SE this afternoon as high pressure moves further to the east. Will let the SCEC across the coastal waters expire as planned. Otherwise, generally light/moderate onshore winds will prevail through Fri. The approach/deepening of the next system over the southern Plains will help to tighten the gradient by Sat. This should result in increased wind speed Sat with Caution/Advisory flags possible at that time. The next cold front is forecast to move into the coastal waters early Sun. Strong northerly winds to develop in the wake of the front and Caution/Advisory flags are likely once again Sun night/Mon. 41 && .PRELIMINARY POINT TEMPS/POPS...
