Area Forecast Discussion National Weather Service Houston/Galveston TX 355 AM CDT Thu Apr 22 2021

SHORT TERM [Through Friday Night]. Surface high pressure is in the process of moving east of the region. Easterly flow along the coast will continue to veer to more of an onshore direction & allow Gulf moisture to begin its return. Partly to mostly sunny conditions early in the day will become cloudy areawide during the afternoon as cloudiness overspreads the region from the southwest. The moisture column will take some time to deepen, and other than some spotty shra's doubt we'll see much in the way of precip until late tonight into Fri morning when we'll see increasing coverage under a strengthening llvl jet.

Large scale lift will increase Fri with the approach of the upper trof to our west. At the sfc, low pres will develop in vicinity of TX/OK Panhandles and the corresponding dryline stretching to the south will and track esewd toward cntl TX during the afternoon. Combination of the above should allow for precip to become widespread across the region as the late morning and afternoon progresses.

Sufficient shear, respectable helicities, somewhat steep mid level lapse rates, and diffluent flow aloft will keep all conditional storm modes/hazards in play during the afternoon into the mid-late evening hours Friday. SPC still has the whole CWA outlooked in a Slight Risk which is reasonable given a bit of model uncertainty in regards to exactly how everything plays out. Areas north of I-10, and more specifically along/north of US-105 may see the higher potential for more significant wx. As one gets further south toward the coast, capping could very well be a limiting factor. In regards to rainfall, expect average amounts of 1-2" north of I-10 with localized higher amounts with any training heavier cells. Precip totals will probably taper down further south to 1/4-1/2" at the beaches. Rain should be pushing out of the area after midnight as the system departs, though we may still see some lingering light precip along the wind shift as it edges toward the coast. 47

.LONG TERM [Saturday Through Thursday]

Some lingering clouds will be possible Saturday morning from Friday night's cold front, but skies will rapidly clear as high pressure builds to the north providing SE Texas an absolutely fantastic weekend. Mostly clear skies, low humidity, and daytime highs temperatures in the low to mid 80s will persist through the weekend. The low moisture values will allow for low temperatures Saturday night to dip down into the low 50s across the north and into the mid to upper 50s across the rest of the area. The high pressure will be fairly progressive as it gets to the Ohio River Valley by Sunday night. This ushers in a more southeasterly wind flow into the area increasing moisture, thus keeping the area a little warmer Sunday night (by around 5 to 10 degrees compared to Saturday night).

An upper level low will be swinging into the Pacific Northwest Sunday night as well. The high pressure to the east and developing low pressure to the west increases southerly flow into the area Monday into Tuesday continuing the warm temperatures, but increases cloud cover. The upper level low exits the Rockies Tuesday night causing a surface low to develop across the Central Plains. This will bring a chance of showers and thunderstorms for our area starting late Tuesday night/early Wednesday through Wednesday evening when the associated cold front moves through the area. There is still some uncertainty on the location/strength of this system and how quickly the front exits the area. But, like the past few system, it looks like areas to the north and east of our region, such as the Red River Valley and into Lousiana, will get the brunt of the precipitation. However, things may change as details come into better view.

AVIATION [12Z TAF Issuance].

As cloud cover increases throughout the day, cigs should gradually fall and probably into the 2500-4000ft range by sunset. Continued lowering overnight with MVFR conditions prevailing. Spotty shra will increase in coverage after 9z Friday followed by shra/tsra during the day. 47

MARINE.

Small craft should continue to exercise caution through the day today as wind speeds remain at around 15 to 20kts. The easterly flow this morning will become southeasterly by the late afternoon. Near advisory conditions will start in the late afternoon this evening as wind gusts climb to 25kts and wave heights approach 6ft. The moderate onshore flow will persist through the day on Friday continuing the need for caution flags or small craft advisories. The persistent onshore flow also bring in higher tides and a high risk of rip currents along Gulf facing beaches on Friday. Guidance currently brings high tide on Friday to about 2.5 to 3ft above MLLW. There will be a chance of showers and thunderstorms on Friday as an upper level low swings through the area. The threat of precipitation and the onshore flow ends early Saturday morning as a weak cold front moves through the coastal waters. High pressure builds in over the area for the rest of the weekend causing light and variable winds with wave heights between 3 and 5ft. Onshore flow returns on Monday as the high pressure slides to the east. This flow increases on Tuesday ahead of the next approaching upper level low that moves through the area on Wednesday.
