New AVIATION

SYNOPSIS
Issued at 311 PM CDT Thu May 2 2024

The main MCS has moved off to the east; however, some development ongoing behind the outgoing MCS is working its way east through the Houston Metro. Expecting this activity to die down by the evening hours. Flash Flood Warnings have been replaced with Areal Flood Warnings as we continue to receive reports of flooded, washed out, and impassable roads. Another round of showers and storms will be possible overnight into Friday morning. Overnight activity is not expected to produce nearly the amount of rainfall that has been observed over the last 24 hours. Rainfall totals will generally be 0.5"-2" with isolated 3-4" totals possible.

SHORT TERM
(This evening through Friday Night)
Issued at 311 PM CDT Thu May 2 2024

Complex forecast continues tonight into Friday morning...while the main MCS has moved east out of the area, a surface boundary lingers in its wake. This is observed with the current line of showers training east through the Houston Metro. For tonight into Friday forecast PWAT values still remain elevated, but the depth of moisture availability is more shallow than what has been available over the last 24 hours. Activity for tonight into Friday is expected to be more scattered in coverage, as opposed to the organized structure that moved through SE Texas today. While that does provide a note of positivity, this is also where the uncertainty lies. Tonight's activity is projected to occur after midnight into Friday morning, and will be heavily dependent on where smaller scale boundaries, pockets of stronger moisture convergence, and higher PWAT values set up, so it is difficult to say which locations will see the isolated higher amounts. At this point current thoughts are that the most likely area for higher totals will be concentrated south of the I-10 corridor. Rainfall totals are expected to generally remain in the 0.5"-2.0" range with isolated amounts of 3.0-4.0" possible.

With the additional expected rainfall, uncertainty of where higher amounts will fall, and the saturated soils from today's rainfall, the decision has been made to keep the Flood Watch in effect through Friday afternoon. Austin and Colorado Counties have been removed from the Flood Watch.

Areal flood warnings are in effect and rivers are forecast to continue to rise (read more about that in the hydrology section below). Please continue to avoid driving through flooded roads, do not drive around barricades, and pay attention to instructions from local officials with regards to any evacuations.

Rainfall chances will continue to decrease through the day Friday.
Friday night will feature mostly cloudy skies with lows in the upper 60s to low 70s.

Adams

LONG TERM
(Saturday through next Wednesday)
Issued at 311 PM CDT Thu May 2 2024

On Saturday afternoon, there is a chance for showers and thunderstorms mainly for far N/NW areas, elsewhere it should remain dry as a shortwave tough moves mainly north of the area.
Another more significant mid/upper tough will move across northern portions of the area on Sunday and will bring a better chance for showers and thunderstorms to SE Texas - mainly along and north of I-10.

Early next week, the focus shifts to drier and warmer weather, with above normal temperatures expected all week. By Tuesday, max temps will reach 90 inland and heat indices will peak in the 95 to 100 degree range. Expect the heat to build during the week with max temps reaching the mid 90s and heat indices peaking in the low 100s by midweek.

AVIATION
(00Z TAF Issuance)
Issued at 642 PM CDT Thu May 2 2024

So far, so good. This afternoon's activity has moved out/dissipated over SE TX at this time with VFR conditions currently in place. But will be expecting a return of lower (MVFR) ceilings as this evening progresses. Hi-res models seem to be backing off from previous fore- casts of the return of strong/organized activity developing late to- night...with only scattered activity progged in its stead. So, have gone ahead and tweaked the TAFs to these trends. Starting a mention of VCSH overnight to VCTS by Fri morning/early afternoon for now. S to SE winds will remain somewhat elevated at 4-9kts tonight...11-19 kts by tomorrow afternoon. 41

MARINE
Issued at 311 PM CDT Thu May 2 2024

Seeing an outflow boundary affect the upper coast early this afternoon, but these NW winds are temporary, and moderate onshore winds will return and prevail through the forecast period. In general, the onshore winds will remain around 15 kts to occasionally 20 kts.
Will continue the caution statement for the evening hours tonight with seas 5 to 7 feet over the offshore waters and 3 to 6 feet over the nearshore waters.

There is a chance for showers and storms, some could become strong, through Friday morning. During the weekend, most of the rainfall is expected to remain inland. Tranquil weather conditions expected next week as mid to upper level ridging builds over the region.
