Area Forecast Discussion National Weather Service Houston/Galveston TX 421 AM CST Thu Jan 23 2020

SHORT TERM (Through Friday).

Showers and embedded thunderstorms have pushed off to the southeast and into the coastal waters. Light winds and wet ground in its wake will lead to some fog development early this morning and portions of the area could very well end up in a dense fog advisory in the next few hours . we'll keep an eye on the obs. Otherwise, expect fog and cloudiness to mix out during the mid and late morning hours. Light westerly winds will become nw and increase as a cool front and drier airmass makes it way thru the area. Mclr skies and seasonable temps are expected tonight and Friday as surface high pressure builds into the region. 47

LONG TERM (Friday night through Thursday).

The medium and long range period will be one of unseasonably warmer weather with periodic rain events primarily focused on Saturday night/Sunday and Tuesday.

Energy rotating eastward from a parent broad upper low over Baja /western (mainland of) Mexico will travel up the Texas coastline this weekend. A clear Friday evening and early Saturday will become cloudier from the southwest to northeast . with light precipitation around Matagorda Bay . during the day Saturday as this energy and main shallow open wave trough travel up the coast. An overcast end to Saturday with increasing probabilities for either light rain, drizzle or showers over the southern half and maritime regions late Saturday through Sunday. The highest rainfall amounts are predicted to fall over the Gulf, or just north and east of the lower level trough apex Sunday. While all southeastern Texas counties will pick up precipitation this looks to be a more wet day the further south you go; from around a quarter of an inch across the northern counties to between a half of an inch to an inch across the coastal counties. Weekend temperatures will start out in the near normal overnight 40s but will only cool into the much more mild 50s Sunday morning per the overcast and wet weather brought on by warm air advection. Days will warm into the upper 60s to lower 70s . or be around 10 degrees warmer than normal per late January standards.

Sunday's rain will come to an end by that evening; skies partially clearing out by Monday morning. The next shortwave trough will approach from a higher latitude . swinging into west Texas from the lower Rockies late Monday. Weak transitory ridging will make for a pleasant and dry Monday with morning temperatures falling on either side of 50 F and the afternoon warming to around 70 F. The approach and passage of the western upper shortwave trough on Tuesday will increase rain chances for showers and maybe some thunder. Have not totally bitten on high POPs on Tuesday mainly due to the significant differences between the very wet GFS and the very dry Euro. The tie-breaker Canadian is also dry so have trended POPs downward from the high deterministic GFS but yet higher than the dry Euro-weighted ensemble; low end chances for showers and isolated storms Tuesday. A cold front Wednesday will veer winds around to the northwest and introduce a cooler and drier mid-week air mass. The late period passage of a long wave trough does not look wet and will likely only fortify this Wednesday-Friday cooler and drier regional air mass. So, the period ends dry with subtle Thursday cooling, lower humidity and north winds. 31

MARINE.

Areas of fog may develop early this morning in the wake of last nights weather system, but should should dissipate toward mid morning. Seas remain quite elevated and will be very slow to fall today so will maintain a SCA for the Gulf waters and a beach hazard statement to cover high surf and the risk of rip currents. Westerly winds this morning will become northwest as a cold front pushes off the coast later today. Onshore flow should resume late Friday as high pressure moves to the east. Unsettled weather can then be expected late Saturday into Sunday as a coastal low develops off the coast . then tracks east. 47

AVIATION.

Low cigs and areas fog should redevelop over the I-45 TAF sites in the next few hours. Exactly how low is questionable, but guidance suggests IFR & possibly LIFR. Expect gradual improvement as we head into the late morning hours as we get some mixing. Would anticipate eroding cloudiness and VFR conditions areawide by early afternoon. Light west winds this morning will become northwest and increase to 10-20kt as a cool front makes its way into the area. Mclr skies are expected tonight and Fri. 47
