Extended Weather Outlook

The National Hurricane Center (NHC) is monitoring an area of low pressure just off of the eastern coast of Florida. This low will track westward across Florida and into the north-central Gulf over the next few days. Environmental conditions are favorable for some gradual development of this low and it could become a tropical depression by the middle to latter part of the week, so the NHC currently has given it a 40% probability of development.

Key Messages A surge of tropical moisture may bring showers and thunderstorms to SE Texas late this week. Slight Risk (level 2 of 4) of Excessive Rainfall for areas east of I-45 on Friday. Marginal Risk (level 1 of 4) of Excessive Rainfall for areas east of College Station through Saturday. What We’re Watching This heavy rainfall threat will greatly depend on how a disturbance over Florida evolves over the next several days. Actions Remain weather-aware and stay tuned for forecast updates!

Low Temperatures Tonight

High and low temperatures for Thursday.

Extended Weather Outlook For Southeast Texas Marginal to Sligh Risk of Excessive Rainfall Thursday through Saturday, mainly East of I-45.
