... Dense fog advisory in effect until 9 am CST Tuesday...
The National Weather Service in Houston/Galveston has issued a
dense fog advisory... which is in effect until 9 am CST Tuesday.
* Event... dense fog limiting visibility to a quarter mile or less.
* Timing... Monday night through after sunrise Tuesday morning. Fog
erosion timing may need to be adjusted based on latest
* Impact... restricted visibilities will create limited sight
distance when driving and motorists will need to use extra
A dense fog advisory means visibilities will frequently be
reduced to less than one quarter mile. If driving... slow down...
use your headlights... and leave plenty of distance ahead of you.

Area forecast discussion National Weather Service Houston/Galveston Texas 851 PM CST Monday Dec 22 2014 Update... two primary concerns with the forecast update tonight...fog /some potentially dense/ and timing showers and thunderstorms associated with incoming front. Surface analysis as of 7 PM placed the cold front surging through Texas roughly along a Texarkana to Temple to Ozona to Carlsbad nm line...with surface pressure rises behind the front on the order of 2 to 3 mb over the past 3 hours. The colder air associated with this front is lagging behind this boundary a bit as 30s and 40s ooze into the Texas Panhandle and western Oklahoma ... little immediate change in temperatures both ahead and behind the front in the middle to upper 50s to near 60. Because of this lag in colder air...low temperatures in the low 50s in central Texas to low 60s along the coast should be on track. Present timing for the cold front has it entering the Houston metropolitan area around 7-9 am Tuesday morning. Both inland and coastal areas are at risk for at least patchy fog development tonight. Generally clear skies and light winds along and south of the Highway 59 corridor have set the stage for a radiation fog event...with several coastal counties already reporting reduced visibilities from fog. Latest rap/hrrr runs show fog continuing to develop along and south of Highway 59 overnight and the previous forecast update handles this anticipated development well. Main question will be how dense fog will actually get /visibility at kbyy has already dropped below 1 mile/. Will continue to monitor trends for potential dense fog advisory later tonight. For more information regarding the update to the marine forecast...please see the marine discussion appended below. Regarding rain chances...regional radar mosaic as of 830 PM showed a complex of showers and thunderstorms over the Permian Basin developing along and behind the front. 00z model data continues to trickle in but the latest solutions still indicate that this activity will continue to spread east towards southeast Texas as the associated upper level system moves across the state. Rain chances will begin increasing along and behind the passage of the front tonight but best forcing for rain development will be along the 850 mb front...delaying highest rain chances around 3-6 hours after frontal passage. Current forecast handles the evolution of tomorrow/S rain...increasing from west to east during the day as the upper level trough passes...fairly well and no changes were made to ongoing rain chances. Huffman && Marine... surface dew points are in the middle 60s and water temperatures are near 60. Some patchy sea fog developed near Galveston earlier and feel some patchy fog could plague marine areas off and on through Tuesday afternoon. Not sure how widespread or dense the fog will become so will just call for areas of fog and watch trends. A strong cold front should reach Matagorda Bay by early afternoon...Galveston Bay around 3 PM and cross the coastal waters by 6 PM. Northwest winds will increase rapidly in the wake of the front and speeds should exceed 20 knots over the entire marine area by 00z with occasional gusts to gale force. A Small Craft Advisory has been issued for the marine areas for late Tuesday afternoon through Tuesday night. The strong offshore flow will drive water out of Galveston Bay and feel the upper reaches of Galveston Bay near Morgans pt and Manchester will suffer from low water issues. A low water advisory may be required late Tuesday night into Wednesday. Moderate to strong winds will prevail on Wednesday before speeds begin to decrease Wednesday night. An onshore flow will redevelop Thursday and strengthen on Friday. Another cold front will cross the marine area on Saturday night. 43 && Previous discussion... /issued 619 PM CST Monday Dec 22 2014/ Discussion... see 00z aviation discussion. Aviation... VFR conds will prevail at most taf sites through 06z with sky conds transitioning to MVFR ahead of a cold front. Kgls had a brief bout with low ceilings earlier in the evening associated with some sea fog just off the coast. Forecast soundings show a reasonably deep saturate layer that feel some light rain will be possible along and behind tuesdays cold front. Ceilings will also lower to IFR/LIFR in the wake of the front. Winds will become strong in the wake of the front as well so will carry a gust group again. VFR conds expected to gradually return after 00z Wednesday. 43 Previous discussion... /issued 535 PM CST Monday Dec 22 2014/ Update... quick update to grids to add mention of patchy fog for coastal areas this evening where afternoon visible satellite and Galveston webcams show a low stratus deck/fog bank sitting just offshore. Guidance depicts winds backing from the southwest to the southeast during the overnight hours and expanded fog mention to inland areas as this occurs...with areas of fog likely developing along the coast courtesy continued low level moisture advection. Huffman Previous discussion... /issued 355 PM CST Monday Dec 22 2014/ Discussion... quite a lot more sun across southeast Texas today than there has been these last few days...with temperatures responding accordingly. Not too many changes with the forecast as models remain in fairly good agree- ment with the timing of the advertised strong cold front. However we are seeing hints that a pre-frontal trough during the overnight/ very early Tuesday morning hours will help to shift winds/limit moist- ure for when the official cold front arrives. Not too comfortable with lowering probability of precipitation too much at this time...given the strong lift with the front itself so will keep with the mostly chance probability of precipitation already in the grids for frontal passage. Nice cool down prognosticated in the wake of this front by Tuesday night as the airmass builds down off the northern plains. Cool/dry weather Wednesday with light/moderate cold air advection will give way to warming temperatures/return of onshore by Thursday (christmas day) as high pressure moves off to the east. Excessive- tended models keeping with the steady parade of fast moving upper level longwave troughs across the U.S. For the rest of the week (on into next week). This should translate to a series of cold fronts for southeast Texas during this timeframe (one Friday then another next tues). All in all a fairly typical El Nino pattern for US. 41 && Preliminary point temps/pops...
