Unsettled week ahead; watching for potential tropical development in northern Gulf

Posted
and last updated

Here's the set-up and a little breakdown of the pattern we're looking at for the week ahead.
Lows tonight: upper 70s
Highs Monday: lower-middle 90s

DISCUSSION:
In the short-term (thru this evening): an impulse of energy will likely help generate a round of storms late this afternoon and evening.

Models are in fairly decent agreement of that occurring.

Some of the storms may contain gusty winds, lightning and heavy rainfall.

Thereafter (rest of week): A leftover frontal boundary will linger across the Gulf coast for several days.

As that interacts with deep tropical moisture, it'll lead to a healthy scattering of showers and storms from Louisiana over to Florida.

As we talked about yesterday, we always have to keep an eye on old frontal boundaries sneaking into the Gulf this time of year as a weak surface low could always try to quickly spin up.

Possible? Of course, and that's why the hurricane center is highlighting the northern Gulf for potential slow development (20%).

Regardless of any development, heavy rainfall is going to be the main concern from this feature.

Who sees the most is still up in the air at this point with the Euro continuing to show concerning amounts for areas off to our east.

Bottom line: The forecast remains quite complex as it continues to evolve. Stay with KATC for the very latest.

Have a great week!
