849 FXUS64 KHGX 032333 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 533 PM CST Sat Feb 3 2018 .AVIATION... Precip in the process of exiting the region to the east. However, ceilings and visibility will continue to diminish in its wake. Expect a mix of IFR/LIFR conditions until late Sunday morning. A weak front will bring a bit of drier air and mix the llvls out and transition things back into VFR territory between 18-21z. 47 && .PREV DISCUSSION... /ISSUED 408 PM CST Sat Feb 3 2018/ A forecast that is neither dramatic, nor terribly quiet. Today looks fairly dreary, but should clear out tomorrow with warming ahead of a weak cold front. Look for another cold front to come through midweek with some rain chances and potentially a thunderstorm, then a more dynamic front at the end of the week, which has a little better shot of bringing some heavier rain with it. May have to keep an eye on rainfall potential with this one, but for now there doesn`t appear to be enough "juice" in the atmosphere to cause any substantial issues. NEAR TERM [Through Tonight]... The radar shows scattered, light showers across much of the area, though our western edges look like the back edge of those showers are beginning to arrive. Water vapor shows dry air and/or subsidence expanding north as the morning`s shortwave exits, and so rain up there should continue to draw down. Showers near the coast may linger into the early evening while another subtle shortwave works through, but it shouldn`t linger too late. Later tonight, expecting some fog to crop up, particularly over the waters (see marine section to come shortly) and near the coast. However, continuing moisture and whatever may still be on the ground from rain today will help contribute across much of the area. Could be some potential for dense fog, and the HRRR buys fully into this idea and crushes Southeast Texas with low visibilities. But thinking that winds will stay up enough to promote a little more mixing and keep that from happening, and keep only patchy fog in the forecast for now. Perhaps the more interesting part about tonight will be temperatures, which are likely to hold roughly steady or even increase tonight as warm air advection kicks in, and 850 temps increase from 7-10C to 15-17C. Continuing clouds should also help this trend as clearing isn`t expected to come until tomorrow. SHORT TERM [Sunday Through Monday Night]... Sunday looks considerably warmer with clearing skies through the day. This should be a pretty brief warmup as this comes along with a very weak cold front that will knock temperatures back into the 60s for highs on Monday along with increasing clouds and some small rain chances, particularly on Monday night once winds have turned onshore and we see a bit of isentropic lift. Along with the turn to onshore flow, we should see dewpoints increase, and as boundary layer warmth improves, a bit of instability may emerge. It`s not progged to be a lot, but may be enough to squeak out a rumble or two of thunder before daybreak, with the best chances near the coast. The surge in dewpoints will also keep Monday night lows up. LONG TERM [Tuesday Through Saturday]... Look for shower and thunderstorm potential to continue through the day Tuesday and into Tuesday night as the next cold front pushes its way in. Not expecting a ton of action as the setup with the upper trough and jet is a bit awkward, and the best instability looks to be to our east, making significant weather more of a threat there. After the front, we should dry out and see temps take a dive for a couple days, with highs in the 50s and lows that may flirt with freezing well north of Houston Wednesday night into Thursday. For Friday, we`re looking for another brief warmup into the 60s, but will be chopped down by yet another front Friday night or Saturday morning. This next front looks more dynamic, and the Euro hints at some heavier rain potential, while the GFS again focuses to our east. At this time it doesn`t appear to be a real big hassle, but could bring an inch or so of rain around and east of Highway 59. They key limiting factor to anything significant appears to be precipitable water given a limited time to recover after the midweek front, only reaching to about 1.5 inches and fairly modest instability again. As long as that scenario holds, not too much to this front either - but some localized issues may develop in the easternmost portions of the area should those parameters end up being of better quality. && .PRELIMINARY POINT TEMPS/POPS...
