New AVIATION
SHORT TERM
(This evening through Saturday night)
Issued at 342 PM CDT Fri May 31 2024
Tonight through Saturday... Generally, a couple more upper level impulses will move through over the next couple of days. There is still a ton of model uncertainty in the timing of these storms. And in general, the models, especially the CAMs, are going to continue to struggle to pinpoint timing until storms are ongoing and start firing up (real-time to near-time weather basically). So, the timing is a factor that will remain quite uncertain over the next few days.
But overall, scattered to numerous showers and storms will be expected, especially during the afternoon and early evening hours with peak daytime heating. These storms will have the risk of hail and damaging winds (30-60mph), based on the lapse rates and instability available. Locally heavy rainfall will be a concern (PWs are quite high, climatologically) and could cause minor flooding or ponding on local roads and make visibility while driving difficult.
The localized flooding risk would be higher for urban or vulnerable locations, as is common for this time of year. Overall, stay weather aware over the next few days as we continue in this unsettled pattern for the atmosphere. MSW
LONG TERM
(Sunday through Thursday night)
Issued at 342 PM CDT Fri May 31 2024
Sunday through mid-week... Sunday and Monday, several more upper level impulses will be moving through the area. These will look pretty similar to the last few days, and there are still a lot of uncertainties in the models regarding timing of the best convection.
Generally though, scattered to numerous showers and storms will be expected, especially during the afternoon/evening hours on Sunday and Monday. On Monday, the bulk of the rainfall will be more for our northern areas, but this could change as we get closer. These storms will, based on model soundings, likely have the risk of locally heavy rainfall, small hail, and winds (30-60mph). Stay weather aware on Sunday and Monday of next week.
Tuesday through mid-week, conditions should be a bit drier as a weak ridge starts to build in over the area. Generally, rain chances will be lower. An isolated shower will be possible, but likely will not be severe at this time, looking at the models. Temperatures will be a little warmer though, as a result. Highs are forecast to be in the low 90s with lows in the mid 70s. MSW
AVIATION
(06Z TAFS)
Issued at 1122 PM CDT Fri May 31 2024
Rain and thunderstorms have completely cleared the area leaving VFR conditions. This should hold through the late night hours, with likely MVFR ceilings and visibilites at KBTR and KMCB early morning before sunrise. Daytime tomorrow will see widespread SHRA and VCTS in the late morning through the end of the period.
MARINE
Issued at 342 PM CDT Fri May 31 2024
Benign marine conditions overall. Generally, southerly to southeasterly winds will prevail with moderate to calm winds (10-15kts) throughout the forecast period. Showers and storms will be possible every day, especially in the afternoon and evening hours, through Tuesday which could produce locally higher gusts.
