Long Term
(Thursday through next Monday) Issued at 251pm CDT Tuesday April 23 2024

Key Messages:

-Minor to moderate risk of heat-related impacts Saturday with heat indices around 105 degrees out west and around 100 degrees elsewhere

The long term looks to remain relatively quiet as it begins with a series of upper level short waves moving across the Great Plains. These shortwaves that will move through the area Friday, Sunday, and Monday. With above normal PWAT (Precipitable Water) values ahead of these short waves (1.7-1.9 inches) an isolated shower/thunderstorm cannot be ruled out each of those days. The caveat is that there isn't any surface forcing available to enhance the environment. The best chance looks to be Monday with Probability of Precipitation chances are around 20% or less in the Victoria Crossroads and Coastal Plains. With the gradient along the ridge tightening over our area, onshore flow will likely increase to Small Craft Exercise Caution to Small Craft Advisory conditions beginning Thurday evening through Sunday.

It will be hot through majority of the long term with high temperatures in the lower 80s to the east and upper 90s to the west. Feels like temperatures out west can potentially reach 105 degrees with lower 90s to the east. Gross I know, but this will unfortunately be the trend through next week.

Marine
Issued at 251pm CDT Tuesday April 23 2024

Weak to moderate southeasterly flow continues this evening through tomorrow night. Weak to moderate southeast flow Thursday is expected to strengthen to over 20 knots Thursday and continue impacting our local waters through Sunday. Therefore, Small Craft Advisory conditions will likely exist Thursday through Sunday. Onshore flow is expected to weaken to weak to moderate Monday and persist through the remainder of the period.
