Area Forecast Discussion National Weather Service Houston/Galveston TX 547 PM CST Mon Jan 27 2020

AVIATION [00Z TAF Issuance].

Upper level trough continues to churn east across New Mexico and should reach Texas tonight into tomorrow morning. Surface low should deepen over north Texas tomorrow morning with a line of convection ahead of a dryline in central Teas. This line should push through the area during the day. Until then visible satellite imagery and obs show a stubborn low stratus cloud deck which may hold through the night. Warm advection will be enough to keep MVFR decks possible through the night with IFR possible in the morning mainly for KIAH/KCLL/KUTS/KCXO. To the south, ceilings should be MVFR but could be more BKN/SCT than BKN/OVC. OVC conditions do set in as the line of showers/storms approaches the area during the day. Ceilings do not improve until behind a cold front that pushes through Tuesday evening/night.

PREV DISCUSSION /Issued 352 PM CST Mon Jan 27 2020/.

SHORT TERM [Tonight Through Tuesday Night].

Clouds have been slow to clear across parts of Southeast Texas today resulting in cooler than expected afternoon highs (so far). Storm system and associated cold front are still on schedule to move into and across the area tomorrow. Before its arrival, look for clouds and possible fog development to return tonight with some showers and possible thunderstorms beginning to enter our northwest areas as early as around midnight but more likely after 3 AM. This activity will spread eastward during the day, and it should be all to the east of the I-45 corridor around or shortly after 6 PM when the cold front moves through the area. Look for cooler, drier and breezy/windy conditions Tuesday night and on into Wednesday morning. 42

LONG TERM [Wednesday Through Monday].

Behind the departure of Tuesday's cold front, moderate northwest winds and benign weather conditions will prevail on Wednesday. Highs should reach the upper 50s on Wednesday afternoon as CAA behind the front supplies cooler and drier air to SE Texas, while nighttime lows should dip into the mid to upper 40s inland and near 50 along the coast. Our next chance for precipitation comes late in the week as an upper trough/cutoff low digs into the southwestern CONUS by Thursday afternoon, allowing for a return to an onshore flow regime and periods of showers on Thursday night and into Friday morning. Rainfall chances still look to be best along the Interstate 10 corridor and along the coast, while amounts once again should be fairly low as PWAT values look to remain in the vicinity of 0.75 to 1.0 in. As this system kicks eastward by late friday, surface high pressure moves into the area in its wake which should provide a dry and seasonable weekend.

Cady

MARINE.

Could see some more fog development this evening and overnight ahead of the Tuesday storm system. Winds are expected to get close to caution levels across our offshore waters, so have gone ahead and hoisted caution flags for our 20-60 nm waters overnight. Winds are expected to come back down during the day tomorrow, then pick back up and swing around to the west and northwest after the cold front and associated showers (and maybe isolated thunderstorms too) move through the area in the mid to late afternoon through early evening hours. Behind the front on Tuesday night and Wednesday, caution flags and possible advisories will be needed for the Bays, and advisories will be needed for the 00-60 nm waters. These rough conditions will improve late Wednesday afternoon and on into Wednesday night as winds come around to the north and northeast and seas begin to come down. Thursday and Friday look wet again as the next system come into the picture. Still anticipating a dry weekend with mainly moderate northwest winds. 42

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
