New SYNOPSIS, SHORT TERM, LONG TERM, MARINE

SYNOPSIS
Issued at 205 AM CDT Sun May 5 2024

- The next round of showers and storms has arrive and will continue into this afternoon. Some storms may become strong to severe with gusty winds and hail possible.
- Flood Watch remains in effect for counties along and north of I-10 through 7pm this evening. Generally expecting up to 1-3" of rain within the Watch area with locally higher amounts of up to 4-8" if and where training storms develop.
- Moderate to Major River Flooding will continue for at least the next several days along parts of the Brazos River, Trinity River and West Fork/East Fork of the San Jacinto River.
- Hot and humid weather will be in place for the majority of the upcoming work-week

SHORT TERM
(Today through Monday Night)
Issued at 205 AM CDT Sun May 5 2024

Showers and thunderstorms, some strong to severe, have already begun to develop north of Montgomery County. We can expect an increase in the coverage of these showers and storms through the next several hours producing a quick downpour of 0.5" of rain or less, gusty winds, and maybe even some hail. The main concern will come during the early morning as a now-developing MCS moves through the region from west to east bringing with it heavy rainfall and a chance of strong to severe thunderstorms. MCS looks to pass through the B-CS area between 4am to 5am, the I-45 Corridor between 6am and 8am, and then through Liberty/Chambers counties by 8am and 10am. Rain rates with the strongest storms within this MCS will be around 1-3" per hour, so the quicker it progresses through the area the better. The MCS will also bring the a threat of strong gusty winds, hail, and cannot out-rule a brief tornado either. SPC maintains a Marginal (level 1 of 5) for Severe Storms across the region.

Once the MCS is through, the rain threat does not end. CAMs have been indicating a west-to-east band of showers and thunderstorms developing and training somewhere across the region in the wake of the MCS. Exact location of where this band of showers and thunderstorms develops will be determined by meso-features unknown at this time, but it is more likely to develop somewhere between I-10 and the Pineywoods region. Chance for showers and storms will continue into the afternoon/early evening hours before dying out.

A Flood Watch is in effect through 7pm for counties along and north of I-10. After all the rainfall we have received in the past week, the soils are very saturated. FFG (both 1 and 3 hour)
are around 2 to 3" for areas along and north of I-10 with Walker County into the Pineywoods region being especially susceptible.
Within the Watch area, generally expecting up to around 1-3" of rain through Sunday evening with isolated higher amounts of 4-8" possible. These higher amounts will most likely be seen where the strongest storms of the MCS move over and where the training line of showers and storms develop. The excessive rainfall outlook for today from the WPC has a Moderate Risk (level 3 of 4) for areas along and north of I-10, Slight Risk (level 2 of 4) for most of the rest of the area with an area of Marginal Risk (level 1 of 4)
for the counties around Matagorda Bay. There is ongoing moderate to major river flooding along portions of the Trinity River, Brazos River, West & East Forks of the San Jacinto River (more on this in the Hydro section below). Not only does this mean that the rainfall that happens today will be slower than normal to drain, but may also see additional rises of the rivers.

Please remember: - Do not drive through or play in flood waters. Never truly know how deep the water is, what is lurking in the waters, nor how fast the water is moving.
- Do not go around barricades. Even if the flood waters have gone down, the ground may not be stable.
- Do no return to homes until officials deem it safe.

Weak midlevel ridging moves overhead Sunday night into Monday, keeping the rain chances low. However, cannot out-rule a pop-up shower Monday afternoon due to lingering low level moisture and daytime heating. High temperatures Sunday will be in the upper 70s to low 80s with overnight lows in the upper 60s to low 70s.
Temperatures rise on Monday thanks to the ridging aloft and southerly flow at the surface with high temperatures in the mid to upper 80s and low temperatures Monday night in the low to mid 70s.
Heat indicies will approach the low to mid 90s on Monday - but this will only get worse as we head into the long term.

LONG TERM
(Tuesday through Saturday)
Issued at 205 AM CDT Sun May 5 2024

Southwesterly flow aloft, southerly flow at the surface bringing Gulf fueled moisture, and mostly sunny skies will lead to our first real taste of summer in SE Texas during the middle part of the week.
High temperatures Tuesday through Thursday will be in the low to even mid 90s for most of the region. Heat indicies will be in the upper 90s to near 100 degrees on Tuesday and Wednesday, and then even up to 105 degrees on Thursday. I even suspect that the very saturated grounds due to the recent rainfall may result in even higher dew points across the area making the heat indicies even worse. Our bodies have not acclimated yet to the heat and humidity, so these early season heat events end up being more troublesome.
While it will likely be below normal Heat Advisory thresholds, there may be a need for a Heat Advisory Wednesday or Thursday since these early season events can be more impactful. Either way, please be sure to stay hydrated and take frequent breaks if needed to be outside and while doing post-flood recovery efforts.

While rain chances will remain minimal through Wednesday, a slow moving boundary from the north will help bring increased coverage of showers and thunderstorms Thursday into Friday. Global models are currently hinting that this boundary is able to push all the through the region with high pressure settling in for Saturday. However, I am not super confident this boundary will actually make it all the way off the coast as we have been burned by this type of feature beyond Day 5 many times during this time of year.

AVIATION
(06Z TAF Issuance)
Issued at 1133 PM CDT Sat May 4 2024

Starting to become active in the CLL-UTS areas with several strong TSRA, and this increasing SHRA/TSRA trend can be expected overnight across the area along with lowering ceilings to mainly MVFR and possible IFR when in/near any storms. Locally heavy rain is possible too. Will carry lingering SHRA/TSRA in the TAFs for the morning and afternoon hours (roughly 12Z-24Z) along with some lifting ceilings. Confidence remains on the high side for the first 6 to 12 hours of the TAFS and on the low side for the last 12 to 18 hours of the TAF. Heading into tomorrow evening/night, will carry MVFR ceilings/visibilities for now.

MARINE
Issued at 205 AM CDT Sun May 5 2024

Can expect increasing showers and storms through daybreak with possibly line of strong to even severe thunderstorms moving through during the early morning hours today (between 5 and 10am). Scattered showers and storms will then be possible through the evening.
Onshore winds around 10 to 15kt with occasional gusts to 20kt will prevail through midweek with seas around 4 to 6ft. Small Craft may need to exercise caution levels at times. Because of the continued onshore flow, there will be a moderate to high risk of strong rip currents through the next several days. Drier, but much warmer conditions are expected through midweek.

HYDROLOGY
Issued at 401 PM CDT Sat May 4 2024

The Flood Watch has been extended to 7pm CDT Sunday evening and expanded to now include Austin/Colorado Counties. Additional heavy rainfall is expected in areas that have already received excessive amounts of rain over the past few days. At this time, we are anticipating an average of an additional 1-3" of rain with smaller areas of 4-8" possible within the watch area. With soils already saturated, this will likely lead to quick runoff and rapid responses along area rivers/creeks/bayous.

Moderate to major river flooding continues for parts of Southeast Texas, particularly along portions of the Trinity, San Jacinto, and Navasota rivers. The following river points are either at or forecast to go into Major flood stage:

- Trinity River (Riverside): Major Flood Stage - Trinity River (Liberty): Major Flood Stage - Trinity River (Goodrich): Major Flood Stage - Trinity River (Moss Bluff): Moderate forecast to go to Major - West Fork San Jacinto (Conroe): Major Flood Stage - West Fork San Jacinto (Humble): Major Flood Stage - San Jacinto (Sheldon): Major Flood Stage - East Fork San Jacinto (New Caney): Major Flood Stage - Navasota River (Normangee): Major Flood Stage

Remember to heed any instructions from your local officials and to never travel through flooded areas or roadways. TURN AROUND, DON'T DROWN. Please monitor updated forecasts via the NWS AHPS website and/or the new NWS NWPS webpage (https://water.noaa.gov/)
as the river flood threat continues.
