Area Forecast Discussion National Weather Service Houston/Galveston TX 1135 PM CDT Sun Apr 5 2020

AVIATION (06Z). Current VFR ceilings (high overcast) are expected to transition/ develop into areawide MVFR categories through the pre-dawn through mid Monday morning hours. A vicinity coastal warm front will keep VCSH around early on the day . the boundary's slow inland movement with afternoon warming will introduce VCSH for very light PM drizzle/showers for more interior terminals. While there will be occasional cloud breaks to VFR through the day, forecast calls for a late day lowering of ceilings back to MVFR and possible IFR by tomorrow evening over more southern hubs. 31

PREV DISCUSSION. /ISSUED 709 PM CDT Sun Apr 5 2020/

AVIATION (00Z) . Areawide VFR ceilings with periods of overnight/early Monday morning MVFR. Drier air working its way in from the east has kept the lower layers dry enough to preclude Sunday rain and lower decks, primarily VFR categories. This will be the trend through the early morning hours but, as winds begin to veer to the southeast, lower level moisture will increase through tomorrow afternoon. Anticipating a near or shortly after sunrise lowering of ceilings back down to MVFR and to remain at these levels through the entire day. A warm front moving onshore will assist in maintaining these lower ceilings and place in the mention of afternoon VCSH along and ahead of this inland moving boundary. 31

PREV DISCUSSION . /ISSUED 346 PM CDT Sun Apr 5 2020/

SHORT TERM [Tonight through Monday] .

Skies have been partly to mostly cloudy this afternoon with temperatures so far in a upper 60s to mid 70s range. Most of the inland areas will see lows in the low to mid 60s tonight while locations at the coast will struggle to fall below 70. Mostly cloudy to cloudy skies will be the general rule overnight, and some patchy fog could develop too. Not a whole lot of changes have been made to the Monday forecast as temperatures warm up into the upper 70s to lower 80s with most locations remaining dry (daytime heating could help to generate some morning showers and isolated thunderstorms in the afternoon, but as of now think 20% chances is all we need in the forecast). 42

LONG TERM [Monday Night Through Sunday] .

A return to unseasonably warm temperatures is in store during the coming week as a persistent upper ridge looks to build over the south central CONUS while an upper trough digs slowly to the south along the Pacific coast. As onshore winds redevelop behind an advancing surface warm front tomorrow, low-level moisture should increase once again across SE Texas. Global guidance indicates a return of PWAT into the 1.75 to 2.0 in range by Monday night, which would place values near or within the upper decile of previous observations for early April. Despite this, a messy precipitation forecast continues to be the story through mid-week. Have maintained greatest PoPs across the northern portion of the CWA with diurnal heading and the progression of any disturbances embedded within the prevailing ridge looking to be the main driver of scattered showers and isolated thunderstorms.

Look for a rising trend in temperatures through mid-week as the upper ridge continues to build, with highs on Wednesday potentially flirting with 90 degrees across the metro area (around 10-15 degrees higher than the climatological normal). Increasing precipitation chances come on Thursday afternoon and into as a surface cold front approaches the area, although timing differences with the passage of the associated surface low are still apparent across global guidance sources. Behind the departing cold front, lingering showers and a return to more seasonable temperatures appear to be in store for next weekend.

MARINE .

Seas have remained elevated and near advisory levels offshore today. Still anticipate a gradual fall, but have extended the caution flags near the coast and the advisory flags offshore into this evening if the decrease continues to take its time. East to southeast winds Monday and Monday night will turn to the south on Tuesday and then persist until a Thursday night-Friday period when the next cold front will be moving into the coastal waters. This is not expected to be a strong front with only slightly elevated northeast to east winds and building seas. At this time, it is looking like only caution flags might be needed for the offshore waters. 42
