SHORT TERM
(Today through Sunday)
Issued at 224 AM CDT Sat Jun 21 2025
Summer officially arrived yesterday. And like most people, we think summer moved in much earlier and as usual, it will overstay its welcome. Highs will move into the mid 90s again today and this will be a common theme throughout the next few months. There will be a few times that we could flirt with the century mark, but that should be a little ways down the road. Heat index readings will be in the 100s though, and this is quite common since it is summer. We have fallen back to a diurnally driven convective cycle and a more normal precip percentage(30-40%) daily. There will be some increase in these numbers every other day or so as additional features swing through. The flow for us will become more SE to NW as the Bermuda High becomes well established and acutally becomes more centered over the western Atlantic even nudging into the east coast over the coming days. The deep tropical moisture moving around this ridging will move directly into our area bringing whatever is in this flow over us. This is not a good thing during the highest probabilities of tropical cyclone season such as August/September but these odds are not as high in June/July. This does not mean it can't or won't happen, we just don't see anything on the horizon at the moment.
LONG TERM
(Sunday night through Friday)
Issued at 224 AM CDT Sat Jun 21 2025
We may not see any tropical cyclones at the moment, but we difinitely see tropical waves(easterly waves) moving over the area and one of these looks to move through Tuesday. These simply boost our precip chances and can be breezy when interacting with the Bermuda High. We will keep with the normal chances of sh/ts into the first of the week but lift those chances for Tuesday, and this may come in during the morning hours around sunrise, especially along the coast. After Tue, precip numbers fall again to a more normal value. With these deep moisture waves moving through, there is always a chance to see waterspouts approaching the shoreline. These are normally weak and land normally disrupts their circulation unless there are stronger upper level processes involved. But each summer a few manage to just cross the coast before dissipating and can cause some wind damage. Otherwise, the rain can be beneficial from time to time as the heat ramps up.
AVIATION
(12Z TAFS)
Issued at 224 AM CDT Sat Jun 21 2025
VFR through this cycle. There is a low chance of TSRA by late afternoon/evening which could temporarily drive these levels lower.
MARINE
Issued at 224 AM CDT Sat Jun 21 2025
Easterly to southeasterly winds less than 15kt is expected throughout this fcast. There is a chance of sh/ts each day and night. Some of these could become strong causing winds to shift and rise abruptly.
