A board, upper-level high over Texas is creating a dome of hot air for much of longhorn state and the southeast.
This high will not be moving much the next few days meaning Acadiana will continue to bake in the hot and humid conditions.
The only good news is slightly drier air is moving over south Louisiana helping to drop heat indices below heat advisories levels but it will still be dangerously hot with feel like temperatures topping out between 102-106° Sunday afternoon.
The drier air is also helping to keep rain chances on the low side at just 10-20% for a few rogue showers on Sunday.
The heat rolls on into next week as highs Monday and Tuesday will be in the low to mid 90s with heat indices between 102-105.
Wednesday the upper-level high should slide back to the west allowing a trough to build down into the southeast producing a decent chance for scattered showers and storms Wednesday afternoon/evening.
On and off showers/storms will continue into Thursday as the trough digs farther south towards the coast.
Thanks to the rain and extra cloud cover that should help to cool off our temperatures for the second half of the work week as highs Wednesday through Friday will be in the upper 80s to near 90.
Beyond Thursday the long range models differ with the Euro going back to a hot and dry pattern while the GFS keeps afternoon showers in the forecasts.
Right now I am going with a blend of the two calling for highs near 90 with a 30% chance for a few isolated showers in the afternoon next weekend into the following week.
