Area Forecast Discussion National Weather Service New Orleans LA 628 PM CDT Mon Jun 14 2021

AVIATION (00Z TAF package).

Will carry VCTS at KMCB for the next few hours due to convection between KMCB and KJAN that is translating south-southwest. With the loss of surface heating, expect weakening of convection, and storms may not reach remaining terminals. Primarily VFR forecast through the forecast period. Threat for TSRA at terminals tomorrow is too low to mention in the forecast, but not zero, primarily after 18z. 35

PREV DISCUSSION. /issued 409 PM CDT Mon Jun 14 2021/

SHORT TERM (Tonight through Wednesday) . High pressure moving out of the NW is bringing drier air to the area. Although model guidance shows a significant amount of instability for today through Wednesday, the amount of drier air aloft will continue to supress much of the rainfall chances. We are outlooked for a Marginal Risk for severe weather on Tuesday. Confidence is low that we will experience the same conditions as we did with yesterday's event but there is still a possibility for a few storm to become severe if they do materialize. High temperatures remain in the low/mid 90s each day and heat indicies remain below advisory critera through at least midweek.

LONG TERM (Thursday and beyond) . There is now a high 70% chance that some type of tropical cyclone will form in the next 5 days. As this low moves northward through the western gulf , it is likely that a tropical depression will form. The biggest impact to the area as of now is still heavy rainfall. It is still too far out to obtain further detailed impacts, but will continue to monitor updates from the NHC on this disturbance.

MARINE . High pressure over the area will cause winds to stay below 10 knots and seas 1 foot or less through at least mid week. Friday, waveheights will begin to see an increase as well as winds as broad low pressure possibly bringing some form of tropical cyclone to the west of the marine area. It is still too far out to know the exact impacts of this disturbance, but confidence is expected to continue to improve as we progress through the week. /TDB/
