New SHORT TERM

SHORT TERM
(Today through Tuesday Night)
Issued at 214 AM CDT Mon Apr 21 2025

The slow-moving boundary that pushed into the area yesterday has stalled along a line extending from southern Austin County northeastwards through NW Harris, Montgomery, San Jacinto and then up through Polk County. This boundary has been the focus of the majority of the showers and thunderstorms over the past 12-18 hours with MRMS data showing a large swath of 1-2" of rain with portions of northern Montgomery County, most of San Jacinto, southern Trinity, and western Polk counties receiving up to 3-5" of rain. While there has been a bit of a lull in the activity overnight with just some isolated showers popping up along the boundary, CAM guidance shows that activity is expected to grow again along and south of the boundary by sunrise. This boundary may continue to slowly meander further south towards the coast through the afternoon, which will bring the showers and thunderstorms along with it. So while yesterday most of the rain fell north of I-10, today its looking more like the more favorable area will be along and south of I-10. Rainfall totals today will be similar to yesterday where most area that get the showers and thunderstorms could see up to 1-2", but there could be isolated higher amounts. Minor urban and small stream flooding is possible, especially if the heavy rainfall ends up over an area of poor drainage. WPC has placed the majority of the I-10 corridor in a Marginal Risk (level 1 of 4) for excessive rainfall today. The showers and thunderstorms are expected to come to an end by this evening with the loss of daytime heating, but scattered showers and thunderstorms will return on Tuesday as a weak shortwave passes through.

High temperatures today will be in the low 80s for most of the area, with the College Station area likely getting into the mid 80s. Overnight lows will be in the mid-60s to low 70s tonight.
Southerly flow returns for the area on Tuesday lead to a slight bump in temperatures (highs in the low to mid 80s, lows in the upper 60s to mid-70s).

LONG TERM
(Wednesday through Sunday)
Issued at 1212 AM CDT Mon Apr 21 2025

Wednesday will be the best chances for showers/storms during the work week as an embedded shortwave trough pushes through the area.
Persistent onshore flow will help keep PW values near or above the 90th percentile (~1.59"), so there'll be plenty of moisture for the PVA to lift. As we have seen recently, with this amount of moisture in place, we could see some locally heavy downpours at times in any of the stronger showers/storms. The synoptic flow remains westerly to southwesterly through the end of the work week, which keeps us in line for additional passing shortwave impulses. As a result, you can expect rain chances to stick around...especially for areas north of I-10. Another shortwave trough looks to pass near the area on late Thursday into Friday. Going into the weekend, there are some hints that ridging aloft may begin to build in which would decrease our chances for rainfall.

Temperatures for most of the work week will be in the low to mid 80s for high temperatures and upper 60s to low 70s for low temperatures.
Going into the weekend is when we'll begin to approach the upper 80s once again as ridging aloft builds in. Based on some of the ensemble guidance and long-range NBM guidance, the warming trend doesn't stop there...

AVIATION
(06Z TAF Issuance)
Issued at 1212 AM CDT Mon Apr 21 2025

Scattered showers and thunderstorms continue around IAH and northward as a slow-moving frontal boundary pushes southward. MVFR ceilings are also prevalent or will become prevalent soon as low- level moisture steadily funnels in overnight. Showers and storms are expected to continue along the frontal boundary overnight and into Monday morning, and there's some indications for additional convective development during the afternoon hours along the I-10 corridor. MVFR ceilings are expected to remain in place through the afternoon hours before lifting back to VFR, but keep in mind that ceilings/visibilities will be locally reduced in and around showers/storms. As far as winds go, they are generally light and variable north of and near the frontal boundary. South of the front, southeasterly winds remain in place. Going into the afternoon, light easterly winds will develop along the frontal boundary before southeasterly winds return as the front begins to wash out.

MARINE
Issued at 1212 AM CDT Mon Apr 21 2025

Winds and seas will be on a downward trend overnight, but seas remain elevated enough for advisories/caution flags to be needed into Monday morning. Generally, light to occasionally moderate southeast winds will persist throughout the work week. The rip current risk still looks to remain elevated this week. After midweek, seas will briefly increase and may approach caution flag territory. Chances for showers and thunderstorms persist throughout most of the week as Gulf moisture interacts with various upper level disturbances.
