New UPDATE
UPDATE
Issued at 729 AM CDT Mon Apr 29 2024
Canceling a portion of the severe ts watch. The remainder will stay through 9am.
SHORT TERM
(Today through Tuesday)
Issued at 209 AM CDT Mon Apr 29 2024
Severe TS watch for the NW valid now until 14z(9am).
Winds will begin to weaken today dropping below advisory thresholds.
But there will still be gusts to 25mph at times and even higher winds up to 40mph associated with the line of storms moving into the area from the west with a few areas along this line possibly severe.
All severe wx modes will be possible and heavy rainfall will accompany as well. The line will begin to speed up as it moves toward the area this morning. Rain rates along the whole line will be 2 to 4 inches per hour. Even though progressive for most areas, there could still be a quick 1 to 2 inches that could overwhelm low lying and poor drainage areas. Totals of 1 to 3 inches with locally higher amounts will be possible with this system. It will likely be a rainy day for most of the day for most of the area as a shield of light to moderate rain develops in the wake of this system and lingers into the early evening hours. As the gradient winds back off, it will cause the coastal flood advisory footprint to become smaller and wind relative headlines will begin to fall over the next 24 hours.
LONG TERM
(Tuesday night through Sunday)
Issued at 209 AM CDT Mon Apr 29 2024
The scenario of fronts moving as far east as Dallas and stalling only to retrograde will continue. This doesn't change a lot locally for much of the upcoming week, but there is a possibility that this front gets oriented east/west and stalls near our area by the end of the week. We will need to see how this plays out through the week but it could bring another good chance of rain to the area.

Mostly MVFR cigs this today but vis will move in and out of IFR levels as there will be +TSRA at most if not all sites today and this will be timed in the 12z taf set.
