000 FXUS64 KHGX 310227 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 927 PM CDT Thu Mar 30 2017 .DISCUSSION... Clear skies, light wind & dry atmosphere allowed for a decent drop in temps once the sun went down. Current forecast looks good and just updated grids to match current obs/trends for the evening update. Lingering dry airmass should allow for a quick warm-up on Friday. Looks like highs will top out around 10 degrees above normal. 47 && .PREV DISCUSSION... /ISSUED 652 PM CDT Thu Mar 30 2017/ AVIATION... No issues for tonight/tomorrow with VFR conditions prevailing. We could see some patchy fog tomorrow night/early Sat morning as on- shore winds/low-level moisture return to the area. 41 PREV DISCUSSION... /ISSUED 407 PM CDT Thu Mar 30 2017/ After yesterday`s storms, mostly sunny skies and light northwesterly winds greeted the region today. Temperatures as of 3 PM CDT had risen into the mid to upper 70s. With clear skies continuing tonight in the wake of yesterday`s system (now over Missouri), radiational cooling will allow for overnight temperatures to fall into the mid 50s to mid 60s. Surface analysis shows a slowly moving cold front dropping south across Oklahoma this afternoon, but the departure of the compact upper low over Missouri will result in loss of mid/upper level forcing for this feature and keep it well north of Southeast Texas overnight. Shortwave ridging will build into the region tonight behind this departing system, with the main axis amplifying east of Southeast Texas on Friday as another system approaches from the Great Basin. This amplified upper ridging will promote another day of dry and mostly sunny conditions on Friday, as well as near record to record high temperatures possible across much of Southeast Texas on Friday. Record high temperatures may be possible again along the Upper Texas Coast on Saturday. Upper flow aloft will become increasingly south to southwest on Saturday as a disturbance shifts from the Four Corners farther into New Mexico. Unfortunately, there is still considerable uncertainty regarding the Saturday and Sunday portion of the forecast as model guidance continues to remain somewhat out of phase regarding timing and placement of features. A surface low looks to develop over the Panhandles with an attendant dryline stretching into West Central Texas as a result, with speed and moisture convergence across West Central Texas associated with the developing surface low encouraging a few isolated showers across the western counties on Saturday morning. Farther west (across the Permian Basin and Low Rolling Plains), diurnal heating along the dryline looks to result in thunderstorm development... with lift from the approaching upper level system possibly resulting in upscale growth into an thunderstorm complex that moves across the state on Saturday night. This could serve as one round of rainfall for the region should this complex develop and actually make it to Southeast Texas. Rain chances will increase more on Sunday, however, as the upper disturbance digs into northern Mexico on Sunday and then sweeps into the region on Sunday night. Precipitable water values surge to 1.5 to possibly 1.9 by Sunday, increasing concerns for at least a locally heavy rain as upper divergence associated with the approaching disturbances promotes the development of numerous to widespread showers and thunderstorms. Several features are in place Sunday to confirm the concern for heavy rain and possibly flooding: a surface reflection/trough and approaching cold front associated with the upper trough that may help focus rainfall, high atmospheric moisture content, and rainfall that has been observed recently (generally across areas south of Interstate 10). However, model solutions from the GFS and European during this time show that some of the synoptic features necessary for a true Maddox heavy rain event (in this case, how the atmospheric moisture in the column is aligned) are out of phase... which raises concerns on the actual severity of the heavy rain threat. This is not to downplay the threat for heavy rain as the region will see rain on Sunday... but the mesoscale appears to be the bigger driver at this point for the materialization of this threat in the region. Adding further to the uncertainty to the forecast for Sunday is the wide spread in forecast rainfall, with SREF 3 hourly QPF plumes advertising a considerable spread anywhere from 0 to 2 inches throughout the day on Sunday. Increasing wind shear associated with the passage of this system may also promote a severe weather threat with stronger thunderstorms on Sunday. Regardless, the passage of this system Sunday night will push a cold front off the coast and end rain chances for the region at the beginning of next week. Dry and warm conditions will become established behind the front through mid-week, but an approaching front may bring low rain chances back into the forecast by Wednesday. Huffman MARINE... North to northwest winds have been coming down this afternoon, and so have the seas. South winds are still on schedule to come back to the area later tonight and tomorrow and strengthen tomorrow night and Saturday when caution flags and/or advisories will be needed. Increasing chances of showers and thunderstorms will accompany the moderate to strong onshore flow over the weekend, and elevated tides might cause some minor impacts over Gulf facing beaches. The next cold front moves off the coast Sunday night and on into Monday with a moderate to strong offshore flow expected to develop in its wake. Look for onshore winds to come back Monday night and Tuesday followed by the area`s next cold frontal passage on Wednesday. 42 CLIMATE...
