New Long Term

SHORT TERM
/Issued 214 PM CDT Fri May 3 2024/ /Through Tomorrow Afternoon/

A Flood Watch is now in effect for eastern Central Texas and the Brazos Valley. This watch will continue through Sunday morning as multiple rounds of heavy rainfall are expected.

The weather across North and Central Texas will remain fairly active as a warm and humid airmass remains established atop our region. As you step outdoors, the humid airmass remains evident with dew point temperatures in the upper 60s to lower 70s. Early morning convection across southern Oklahoma sent an outflow boundary southward, meanwhile, ongoing storms across Central Texas continue to push northwestward. These outflow boundaries will likely be the focus for isolated convection across North Texas this afternoon. Given a lack of strong flow, any convection is likely to remain highly disorganized and fairly short-lived.
Nonetheless, lighting and gusty winds will remain possible with any of the storms this afternoon.

Across eastern Central Texas, another remnant boundary continues to be the focus for occasional bouts of heavy rain through the rest of this afternoon. Considering the antecedent conditions, a quick 1-2 inches of rain can lead to flash flooding.

Storm chances should dissipate around or shortly after sunset as daytime heating comes to an end. This is when we'll turn our attention to the dryline across West Texas, where storms are once again expected. Although the dryline will likely be about 100 miles west of our region, storm motion this evening will be to the east with a few storms arriving to our western-most counties by 9-10pm. Given the storms will become increasingly displaced from the source of lift, expect storms to gradually dissipate trough the night. There is a low (~20%) chance of showers or storms approaching the I-35 corridor closer to midnight. Storms would be decaying, thus, the threat for severe storms would remain low.
Tonight, expect cloudy and above normal temperatures will lows remaining in the mid to upper 60s areawide.

Our next rain chances will arrive tomorrow as a cold front moves southward across our region. A shortwave trough will be migrating eastward, likely firing off thunderstorms along the leading edge of the front. At this time, the greatest rain chances will likely be beyond sunset tomorrow, however, a few isolated showers and storms cannot be ruled out between noon and sunset. Any storms that do develop in the afternoon could contain small hail and gusty winds. High temperatures tomorrow will be in the upper 70s to lower 80s with southerly winds continuing.

LONG TERM
/NEW/ /Saturday Night Onward/

An active weather pattern will continue Saturday night as a shortwave embedded in the subtropical jet lifts northeast across North and Central Texas. Thunderstorms will likely be ongoing at the start of the period across the Big Country, and will spread east across the region overnight into Sunday morning. A wind and hail threat may accompany these storms across the western half of the region Saturday evening, but convection will be weakening Saturday night while moving into a less favorable environment.
Despite the severity or lack thereof, the presence of a quasi- stationary surface boundary will maintain a threat for more heavy rain and flooding. This threat will be highest over Central Texas where heavy rains have already occurred, and where the front will most likely be located (and is currently exacerbating the ongoing flooding across the Brazos Valley and Southeast Texas). A Flood Watch has hence been issued through around midday Sunday for those Central Texas Counties who have experienced multiple rounds of heavy rain over the past several days.

Convection will move out during the morning hours Sunday, making for an overall decent day with highs mainly in the 70s. There may be a few rogue showers that pop up in the afternoon but those should be few and far between. Attention will then turn to a larger scale upstream trough, which will cross the Rockies Sunday night, then lift northeast through the Plains on Monday. Most of the ascent associated with this system will remain to our north, but we will still likely have isolated dryline-induced convection Monday afternoon and evening. Coverage may be low due to the presence of a capping inversion, but we will otherwise have a warm and unstable environment in place, and any storms which develop could become severe.

The passing of the shortwave will send a cold front south into the area Tuesday night. After a quiet Tuesday, the front will again provide a focus for convection starting Wednesday, as a longwave trough produces cyclonic flow overhead for the mid to late week period. Scattered showers and storms should develop in the afternoon and evening hours Wednesday and Thursday. Not all will receive rain, but just about any of the area could see a shower or storm. By Friday, the front will have sagged well south of the I-20 corridor, unfortunately focusing convection across the saturated Central and Southeast Texas. The front and trough will both shift southeast of the region on Saturday, providing dry weather and overall nice conditions in time for Mother's Day weekend.

AVIATION
/Issued 108 PM CDT Fri May 3 2024/ /18Z TAFs/

Concerns...Low storm potential this afternoon. MVFR/IFR expected once again tonight through tomorrow.

With the unsettled weather pattern continuing atop North and Central Texas, there will be a renewed chance of isolated storms within the D10 airspace this afternoon. Coverage will remain minimal, but some impacts to aviation traffic will be possible.
Any storms that do develop will dissipate after sunset as south winds persist.

The dryline, which will be across West Texas and the Texas Panhandle, will once again fire off thunderstorms this afternoon.
Storms are expected to remain west of the D10 airspace, however, any westward traffic may see impacts due to the afternoon and evening convection.

Ceilings will be deteriorating overnight, with MVFR around midnight, then IFR closer to 08Z. This trend is fairly similar across Waco where a similar airmass will be in place. The sub-VFR ceilings are expected to linger through tomorrow morning before improvements begin in the afternoon.

Storm potential tomorrow afternoon remains too uncertain to mention in the TAF. There is higher confidence in tomorrow night's convection, however, that is beyond this forecast cycle.
