SHORT TERM
(Today through Monday)
Issued at 157 AM CDT Sun May 19 2024
After a good soaking along with some severe wx, we are ready for a break. A back door trough will be moving through today, this can actually be seen in radar returns this morning just to the NE of the area. We are calling this a trough since there is only weak air mass change, and the only change is found in PW values as they drop from around 1.4" this morning to around 1" by this afternoon. This won't stay around too long and we will be back to ruturn flow Monday. The only thing of concern will be fog this morning as the boundary moving in and conditions ahead of this boundary are ripe for radiation fog. There is only one variable that is not wanting to play along and that is a northerly wind that is supposed to be all the way to the coast by daylight today. The wind is not strong, but since it is bring a degree or two drop in dew pts, there is concern that fog will not form until right at sunrise(sunrise surprise).
This is by far the hardest fog to fcast, but if this looks to be the case just before sunrise, we will bring up a dense fog advisory for inland areas south of the boundary. Since this boudary will be at the coast tonight, fog should not be an issue tonight(famous last words).
LONG TERM
(Monday night through Saturday)
Issued at 157 AM CDT Sun May 19 2024
Warm and humid will be back for the next several days but then again it is the start of summer, so these conditions are not unusual. The only thing concerning concerning weather will be by the end of the week. But these MCS features look to stay to the north of the area by late Thu into Fri. It is possible that some of this could make its way to central LA/MS. But as far as it getting here, this does not look to be the case at the moment.
AVIATION
(12Z TAFS)
Issued at 157 AM CDT Sun May 19 2024
Some inland terminals could see very short duration IFR due to vis this morning around sunrise, but the remainder of this cycle should be VFR.
MARINE
Issued at 157 AM CDT Sun May 19 2024
Storms will slowly move south and east and dissipate today from the outer waters. Easterly and westerly winds across the frontal boundary will also become southerly to start the new work week.
Southerly winds will remain the common theme for the rest of the week and no other systems are expected to impact the coastal waters through the rest of the week.
