FXUS64 KBRO 222012 AFDBRO AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BROWNSVILLE TX 312 PM CDT THU AUG 22 2013 .SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...THE 500 MB TROUGH AXIS THAT INFLUENCED OUT WX OVER THE LAST COUPLE OF DAYS WILL GRADUALLY WORK ITS WAY WEST TONIGHT AND TOMORROW. HOWEVER ANOTHER 500 MB INVERTED TROUGH AXIS NOW LOCATED OVER THE GULF OF MEX WILL PUSH WEST THROUGH FRIDAY NIGHT EDGING CLOSER TO THE TX COASTLINE. THE 12Z BRO SOUNDING INDICATES A PRETTY MOIST AND UNSTABLE AIRMASS IN PLACE OVER THE REGION WITH A >2 INCHES AND A CAPE OF 4763 J/KG. THE NAM AND GFS FORECAST SOUNDINGS MAINTAIN PWATS NEAR 2 INCHES THROUGH TOMORROW NIGHT WITH A LITTLE LOWER BUT SUBSTANTIAL CAPE VALUES RANGING GENERALLY FROM 2000 TO 3000 J/KG IN THE SHORT TERM. DESPITE DEEP SOUTH TX BEING WEDGED IN BETWEEN THE TWO TROUGH AXES BELIEVE THAT ENOUGH TROPICAL MOISTURE AND INSTABILITY WILL REMAIN POOLED OVER THE REGION TO INTERACT WITH THE DAYTIME HEATING TOMORROW AFTERNOON TO GENERATE ANOTHER ROUND OF ISOLD/SCT CONV. THE NAM GUIDANCE REMAINS ON THE WETTER SIDE VERSUS THE GFS AND WILL GO WITH A BLEND OF THESE TWO MODEL SETS FOR SHORT TERM POPS AS BELIEVE THAT THE MAV MOS MAY BE UNDERESTIMATING THE CONV POTENTIAL FOR TOMORROW. THE ECMWF MOS GUIDANCE WAS NOT AVAILABLE AT AFD TIME FOR ANY COMPARISON. SOME LOCALLY HEAVIER DOWNPOURS MAY BE A PROBLEM THROUGHOUT THE REST OF TODAY AND INTO TOMORROW AFTERNOON. BELIEVE THAT THESE CAN BE HANDLED WITH SPS/FLS ISSUANCES. THE NAM HAS A LITTLE COOLER BIAS VERSUS THE MAV MOS GUIDANCE SINCE THE NAM HAS HIGHER POPS. WILL GO WITH A BLEND OF THE NAM AND GFS MOS TEMPS THROUGH TOMORROW NIGHT. .LONG TERM /SATURDAY THROUGH THURSDAY/...AN INVERTED 500MB TROUGH ACROSS THE WESTERN GULF OF MEXICO SATURDAY WILL CONTINUE TO PROVIDE UNSETTLED WEATHER ACROSS SOUTH TEXAS THROUGH THE WEEKEND AS ABUNDANT MOISTURE ACROSS THE GULF OF MEXICO CONTINUES TO MOVE ACROSS THE AREA UNDER THE 500MB RIDGE ACROSS THE CENTRAL UNITED STATES. THE SEABREEZE SHOULD BE THE MAIN FOCUS FOR ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP SATURDAY AND SUNDAY. THE UPPER LEVEL RIDGE ACROSS THE SOUTH CENTRAL AND SOUTHEAST U.S. SHOULD PREVAIL THROUGH NEXT WEEK BUT MOISTURE WILL REMAIN HIGH ACROSS THE GULF OF MEXICO MONDAY AND TUESDAY SO WILL CONTINUE TO MENTION A CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH TUESDAY BEFORE SUBSIDENCE INCREASES WEDNESDAY INTO THURSDAY AND THE MOISTURE DIMINISHES ACROSS SOUTH TX. && .MARINE... TONIGHT THROUGH FRIDAY...BUOY020 CURRENTLY REPORTS SWELLS ONLY AROUND 1.5 FEET WITH NORTHEAST WINDS ONLY AROUND 5 KNOTS. A WEAK PGF WILL PREVAIL ACROSS THE GULF OF MEX THROUGH TOMORROW NIGHT WHICH WILL MAINTAIN FAIRLY LIGHT TO MODERATE E-NE SURFACE FLOW. ACCORDINGLY...THE GULF SWELLS WILL LIKELY REMAIN IN THE 1 TO 3 FT RANGE WITH NO SCA CONDITIONS EXPECTED. SOME ADDITIONAL SMW'S MAY BE NECESSARY IF STRONGER CONVECTION FORMS LATER TONIGHT THROUGH FRI NIGHT. SATURDAY THROUGH TUESDAY...LIGHT TO MODERATE SOUTHEAST WINDS WILL PREVAIL ACROSS THE COASTAL WATERS SATURDAY AND SUNDAY WITH HIGH PRESSURE ACROSS THE NORTHEAST UNITED STATES AND WEAK LOW PRESSURE ACROSS THE SOUTHWEST GULF OF MEXICO. THE PRESSURE GRADIENT WILL REMAIN WEAK ACROSS THE WESTERN GULF OF MEXICO EARLY NEXT WEEK.

Knocked 3 degrees F off today's highs across the board for land areas. Also extended slight chance PoP's out to 20Z to handle current trends. && .DISCUSSION...Updated for latest aviation discussion below. && .AVIATION...A few light, passing showers may still occur for the next couple of hours at the terminals. Winds remain on the breezy side. Per satellite trends and RAP/BUFKIT forecast soundings, not expecting BRO to break out of MVFR ceilings this afternoon for any appreciable amount of time. MFE already at VFR; lower confidence for HRL, but think CIG's will eventually raise/scatter out for a few hours. Short-term guidance rather insistent on bringing IFR ceilings into BRO and HRL early this evening, with MFE more likely to remain MVFR further inland. SE winds stay elevated overnight as pressure gradient tightens locally. Winds kick up to gusty mid- morning on Wednesday. CIG's lifting to MVFR probable. && .PREV DISCUSSION... /issued 642 AM CDT Tue May 1 2018/ DISCUSSION...Updated for latest aviation discussion below. AVIATION...Low clouds continue to spread across the region, trapped underneath a drier inversion. LLVL jet continues to race through the region, with 40 to 50 knot winds from 2000 to 8000 feet. Some mixing of gusty winds down to the sfc is expected today, with gusts approaching 25kts. Current low cigs will lift through the morning, with VFR conditions expected this afternoon. There is some light drizzle in the area, which will let up later this morning. Windy conditions are expected to continue overnight tonight, with southerly winds of 15G25kts expected to continue. PREV DISCUSSION... /issued 410 AM CDT Tue May 1 2018/ SHORT TERM (Now through Wednesday): H5 trough continues to drift across the intermountain west, with the latest ridge well off to the east of our area. Dry air continues to draw into the region above 5000 feet, keeping a strong cap on the atmosphere. Surface low pressure developing across western KS is increasing the gradient and inducing a LLVL jet along the coast. 40 to 50 knot winds are noted between 2000 and 8000 feet, racing northward. The strongest core of the jet is above the inversion, so mixing of the strongest energy will be held back some today. Tighter sfc gradient will still mean some gusty winds during the afternoon. Ample moisture trapped under the cap and daytime heating will cause some bubbling up of showers along the coast, although wind shear will inhibit any meaningful development. Any showers that can form will be very weak and brief, not enough to keep my flowers alive. Low pressure remains across Kansas tonight, keeping the gradient tightened up along the coast. The llvl jet will shift slightly offshore tonight, keeping the breeziest conditions offshore. Another warm and mostly cloudy day expected Wednesday with moisture still trapped underneath the inversion. Will keep an eye on light shower chances for tomorrow morning, but threat looks too low for overall forecast for now. LONG TERM (Wednesday Night through Monday): 500mb low/trough across the southwest United States and northwest Mexico Wednesday will become elongated Thursday before developing into a shortwave trough on Friday and moving eastward across the state Saturday. Rain chances should remain to the north and west of the CWA Wed night through Thursday before convection across southwest Texas and northeast Mexico begins to develop and move into the far western portions of deep south Texas Friday. Showers and thunderstorms are expected to increase across the area Saturday as a weak cold front moves southward across south Texas. Rain chances will diminish Sat night into Sunday as the upper level trough moves eastward and northwest flow aloft brings drier air into the Rio Grande valley. Breezy conditions will continue Wed night into Thursday before the pressure gradient weakens across the lower Texas coast Friday. Temperatures will be near normal Wed night through Friday before becoming slightly below normal this weekend as the increase in clouds and rain chances limits diurnal heating across deep south Texas. MARINE (Now through Wednesday): Advisories expire at 5AM, and will not be extending as winds remain in the 15 to 20 knot range, and are forecast to remain there through the day. Southeast flow continues to move northward towards developing low pressure in Kansas. LLVL jet will shift just offshore overnight, and with some nocturnal marine mixing, will bring breezy conditions for the open Gulf waters tonight and possibly into Wednesday. Will likely need to reintroduce Advisories for the Gulf waters for the overnight hours. Breezy conditions will keep wave action up today, with waves above 5 feet and a significant chop on the Laguna. Wednesday night through Saturday...Moderate to strong southeast winds will prevail across the coastal waters Wed night into Thursday before the pressure gradient weakens across the lower Texas coast Thurs night. Moderate southeast winds will prevail across the western Gulf of Mexico Thurs night into Friday. A weak cold front will move into south Texas Saturday and winds will back to the east and diminish. Small craft advisories will likely be needed for the Laguna Madre on Thursday and for the offshore waters Wed night through Thurs night before winds and seas diminish Thurs night into Friday. && .BRO WATCHES/WARNINGS/ADVISORIES...

A 500mb low/shortwave trough across Baja California tonight will allow low to mid level moisture to increase across central Mexico tonight into Wednesday. Some of this moisture will reach the Rio Grande valley Wed afternoon as the surface ridge across south Texas today moves eastward Wednesday allowing an onshore flow to return tonight into Wednesday. Rain chances will remain south and southwest of deep south Texas Wednesday. Below normal temperatures today will return to near normal tonight and continue to be near normal through Wednesday. .LONG TERM (Wednesday Night through Monday): The weather quickly transitions from comfortable autumn and a clean airmass to warmer and somewhat more humid to close the week and dominate the weekend into early next week. The end of November warm-up won't be enough to dent a notably below average month, the first such month since January and notable for the departures from normal which will settle in around 3 to 4 degrees below the 1981-2010 averages. Before the above to much above average air arrives...the Valley and northeastern Mexico will see a rapidly dampening 500 mb short wave move through. The vigorous closed wave arrives on the northwest Mexican coast east of the southern Gulf of California Wednesday evening, then moves quickly through northern Mexico overnight and early Thursday before shearing out across the Valley and western Gulf later Thursday and Thursday night. The system will induce sufficient lift for scattered showers favoring the Lower Valley and especially the Lower Texas Gulf waters, with much lesser chances of measurable rainfall along/west of US 281/IH 69C. The best chances are Wednesday night into Thursday morning before activity energizes nicely later Thursday and Thursday night over the warmer waters beyond 20 nm out and peaking over the Gulf out toward the shelf. Zonal flow takes over Friday through Saturday with Deep South Texas and the RGV on the warm side of the carved-out atmospheric "bowl" that will produce unsettled late autumn weather traversing the eastern Rockies and central Plains. A developing 500 mb trough across the central Rockies Sunday will slide into the central Plains Monday, with southwest flow aloft increasing warmth in the column and bringing temperatures potentially threatening 90 to inland locations of the Rio Grande Valley each day. The next decent front should follow Monday night and Tuesday...but details are uncertain now and will defer to future forecasts for expected outcomes. For the sensible weather...made only a few tweaks to rain chances and timing Wednesday night and Thursday but the main change was to push up low temperatures several degrees given modest southerly flow and plenty of cloud cover for most areas, with the only 50s possible across the Zapata/Jim Hogg ranchlands where skies may be partly cloudy and winds light. The light winds and higher dewpoints will support some fog development. Fog thickness is uncertain this far out so only went with patchy for now. Temperatures will pop over 80 for most areas (except the immediate coast) Thursday as skies become partly to mostly sunny from west to east. The only exception may be the southeastern Cameron County coast where pesky clouds and a few showers are likely to hang on through the day. Any rain shifts into the Gulf overnight Thursday, and with just enough southerly flow expect fog to be kept to a minimum as temperatures and dewpoints climb. Would not be surprised to see some areas hold at or just above 70 by Friday morning, but with partly cloudy to mostly clear skies (perhaps some low overcast toward daybreak) only raised a few degrees into the 60s for all areas...also in line with guidance consensus. Friday through Sunday could see afternoon temperatures approach 90 in a few spots depending on sunshine and how much dry/downsloping air slides off the Sierra Madre above the surface. Model guidance may be struggling to handle the late summer-like atmospheric profile and keeping forecast high temperatures a bit too low. Blends are lower still, so disregarded and forecast is closest to the warmer GFS MOS each day. A weak wind shift line briefly turns winds to the north Saturday afternoon (which may enhance the downslope component) before southeast flow quickly returns overnight and continues through early Monday. With the Saturday "front" in name only and the return flow right behind in just six to twelve hours, Sunday and Monday minimum temperatures were raised significantly...with most areas remaining well in the 60s (cooler across the ranchlands where drier air will make brief appearances Saturday and Sunday afternoons) through daybreak both Sunday and Monday. Bottom line? Keep those warm weather clothes close by. December comes in like a lamb. && .MARINE (Today through Wednesday): Seas were near 5 feet with north winds near 12 knots at buoy020 early this morning. Light northeast winds will prevail across the coastal waters today with surface high pressure across south Texas this afternoon. Winds will veer to the southeast tonight as the surface ridge moves eastward. The pressure gradient will increase across the lower Texas coast Wednesday as low pressure develops across the Texas panhandle and the surface ridge across the eastern Gulf of Mexico allows winds to veer to the south and increase. Moderate south to southeast winds will prevail across the western Gulf Wednesday. Wednesday night through Saturday night: Southerly flow will pick up especially beyond 20 nautical miles where the marine layer is marginal (sea surface temperatures in the mid to upper 70s) and there may be a window through Friday night where caution conditions for winds (15 to 20 knots) and seas (building back to 6 feet) develops. For Wednesday night, showers are likely over the offshore leg and have raised chances to account. Did not include thunder with this forecast but instability over the warmer water toward the shelf along with decent forcing could make this reality...and will let later shifts evaluate. Precipitation will exit stage right steadily on Thursday with fair weather the rest of the way. Closer to shore, analyzed SST between 66 and 70 will set up enough of a marine layer to keep winds below caution levels through Friday and seas in the moderate range, with perhaps a window of caution (15 to 20 knots) Friday night ahead of the wind shift that only sneaks into the waters mainly north of Mansfield on Saturday. The slightly lighter winds Saturday and Saturday night will improve waves/seas in all waters but probably not until Sunday for improved boating/fishing for most. && .PRELIMINARY POINT TEMPS/POPS...
