New SHORT TERM, LONG TERM, MARINE

SHORT TERM
(This evening through Monday night)
Issued at 325 PM CDT Sun Apr 20 2025

Onshore flow continues to feed moisture into the area which has helped several spotty showers form today. Chances for these spotty showers will continue into the evening hours before we see better rain chances on Monday. These increased rain chances come as a frontal boundary comes to a slow just to our north and west and stalls out. It is also a little bit gusty out there today due to the surface pressure gradient, but this will start to ease as we head into the evening and overnight hours.

Taking a look at some CAM forecast soundings for Monday, I would not be surprised to see a storm or two drop some near severe hail or have some locally strong wind gusts. 500MB temperatures are ~-12C, DCAPE is ~500-700J/Kg, and lapse rates look to be plenty supportive. The only noticeable issue is the lack of shear, but a few strong to near severe storms cannot be ruled out.

LONG TERM
(Tuesday through Saturday night)
Issued at 325 PM CDT Sun Apr 20 2025

Tuesday will continue to see scattered rain and storm chances throughout the day, with PoPs peaking in the afternoon hours around ~60-70% especially for the northern half of the CWA A couple disturbances from Texas will move through our area throughout the long term period, or at least through Thursday, before we quiet down some into the weekend.

Late Tuesday evening an MCS looks to fire back in western Texas that will move this way. Both the globals do show this MCS making it into at least a portion of our CWA during the day on Wednesday.
Additionally, any residual outflow boundaries or sea/lake breeze boundaries will serve as some lift for showers and thunderstorms to fire at random across the area. Overall, following a very dry couple weeks for us we do look like we are heading back into a more active pattern.

AVIATION
(18Z TAFS)
Issued at 1225 PM CDT Sun Apr 20 2025

VFR conditions will persist through this afternoon, but heading into the evening hours we will see the return of lower cigs. This brings MVFR and eventually IFR conditions overnight due to the lower ceilings. Possibility of some patchy fog, mainly for MCB area, around daybreak bringing some IFR vis.

MARINE
Issued at 325 PM CDT Sun Apr 20 2025

Winds have backed down some from earlier this morning which allowed the Small Craft to fall off at 10am. We will continue to see winds come down as the pressure gradient eases late this evening and overnight. Otherwise onshore flow will continue through the next several days, but remaining on the lighter side as we don't really see any organized systems roll through. Several rain and storm chances through the week however, which could bring locally higher gusts and waves at times.
