light to occasionally moderate southeast winds become established today, and this southeast flow will then persist through the week. Expect winds to gradually strengthen later on in the week, and there may be times when small craft will need to exercise caution.

SHORT TERM
(Today through Monday Night)
Issued at 312 AM CDT Sun May 19 2024

The City of Houston experienced just its second 90+°F day of the year on Saturday, but there's plenty more where that came from! Before we get to that though...if you have any plans to hit the roadways later this morning, be aware of the potential of patchy dense fog. With light winds, saturated soils, and clear skies allowing for radiational cooling to drop temperatures to the dew points, we have a fairly decent fog setup. We are a bit drier this morning though thanks to the plentiful sunshine on Saturday, so the fog likely won't be quite as widespread. Locations west of I-45 look to have the best odds of patchy fog this morning. Any fog that develops will burn off by 9-10am. From there our attention turns to the hot temperatures once again. With ridging aloft still in place, we're expecting another day with high temperatures in the low 90s.
Heat index values will be in the upper 90s once again, but at least we'll have a noticeable southeasterly breeze this time around. That southeasterly breeze is a blessing for now (especially for those still without power), but will be part of our downfall later on in the week when you see what the additional humidity does to our heat index values.

Monday will be just about the same as Sunday, but a little bit breezier thanks to a tighter pressure gradient. A shortwave trough pushes through the Central Plains and generates surface low pressure on the lee-side of the Rockies. As the low deepens and nudges eastward, it tightens our pressure gradient further. It also places us in its warm sector, so we'll start to see our humidity climb further thanks to the enhanced moisture transport. This leads to heat index values seeing a slight rise into the 96-100°F range. The upward trend in heat index values don't stop there, so it remains very important to keep heat safety as a top priority...especially for those still without power. Overnight lows will increase from the low 70s tonight to the mid/upper 70s Monday night, so there's not much relief from the warmer temperatures. Be sure to take the proper precautions to protect yourself and your loved ones from the stresses of heat: drink plenty of water, take frequent breaks, avoid strenuous outdoor activities during the hottest part of the day, know the signs of heat stroke/heat exhaustion, and ALWAYS ALWAYS ALWAYS look before you lock your vehicle. Don't forget about your pets as well! If the ground is too hot for the palm of your hand, then it is too hot for their paws.

LONG TERM
(Tuesday through Saturday)
Issued at 312 AM CDT Sun May 19 2024

Heat continues to be the main concern in this forecast period. The area will remain on the northern edge of mid/upper level ridging, but a weakness in the ridge still looks like it could develop around midweek that could allow for possible showers/thunderstorms to enter the area (mostly in our northern counties where the weakness is strongest and an eastward moving disturbance/impulse skirts across the area).
Will close out the week and start next weekend on the dry side for now, but we will need to keep an eye on the strength of the ridge as any weakness on the northern fringes could allow for another chance of rain (again, mainly across our northern counties).

For high temperatures, will generally stick with around 90 to the low 90s Tuesday through Thursday, then trend upward a degree or two (around a 90 TO 96 range) heading into Friday and Saturday. Low temperatures will be on the warm side too, generally in a 72 to 77 or 78 degree range throughout the period.

Peak heat index values will be in the low 100s daily (generally 100 to 105), so make sure all heat safety precautions are being taken to stay safe!

(18Z TAF Issuance)
Issued at 1231 PM CDT Sun May 19 2024

VFR prevailing through the period. Included TEMPO for 12-14Z for a few sites for potential for patchy fog that could lead to MVFR VSBYs. Otherwise, high clouds expected with light SE winds.

MARINE
Issued at 312 AM CDT Sun May 19 2024

Light to occasionally moderate east to southeast winds today will become southeast tonight and Monday, and this southeast flow will then persist and gradually strengthen for the remainder of the week. Caution flags might be needed for the increasing winds and building seas.
