KEY MESSAGES

Issued at 1257 AM CDT Wed Jun 17 2026

- Hot and humid conditions will build today over our north and west with best rain chances remaining from Lufkin to Monroe. Heat index will keep in check today, but loom large Thursday.

- The threat for excessive rainfall and potential flooding will linger over deep east Texas and north Louisiana with slow storm movement and soaked soils through mid to late week. - The potential for additional heavy rainfall and additional flooding may return to portions of our Four-State area with a weak cool front pooling the heat and humidity into the weekend.

DISCUSSION

Issued at 1257 AM CDT Wed Jun 17 2026

Quiet evening for us with fair skies likely to cloud up with more low status early around daybreak and into mid morning. It will be warming up for us again with southerly flow back in play. The winds will be brisk at times over our southern tier of Co/Pa adjacent to the action in the Gulf of America. The NHC is closely watching PTC One, which is largely unchanged at this point, but there is a big uptick in convection just offshore of the TX coastal bend. Daylight will enhance seeing the low level circulation, but for now lighter W/NW winds aloft will keep storm motion slow, until the anvils get up like spinnakers on a sail boat, moving storms more quickly with maturity. Low top development will have potential to bring excessive amounts quickly with still over 2 inch PWAT on both Lake Charles and Jackson soundings this evening, while Shreveport's was 1.77", thus showing the need for the Flood Watch to continue for now.

The heat will build areawide, but more the case over OK/TX and north of I-20 for LA/AR. The heat index will behave at least for today, but calculations for Thursday may require a Heat Advisory. However, a regardless of the coastal influences, a weak cool front will drop down over the MS River Valley and settle into to our area by early Friday for a soggy Juneteenth. This is due to the large area of convergence of SE winds south of I-20 and NE winds across AR and down to along I-20 into LA. So what we will see in a brief heat threat may be replaced by more flooding again with the WPC EROs shading more Slight risk and more Moderate risk for our area over the next 3 days. Then slowly relenting back to Marginal by early Saturday. The SPC elevates General severe risk to Marginal risk ahead of the cool front.

So a lot of rainfall remains our biggest threat along with a hot day on Thursday ahead of the sinking backdoor air mass, adding some compressional heating to build storms that will be capable of lingering overnight, through Friday and into early Saturday. So suffice it to say, stay abreast of the latest forecast and potential changes with the east meets west scenario. /24/
