SHORT TERM
(Today through Saturday)
Issued at 235 AM CDT Fri May 17 2024
Although there are a few storms remaining early this morning, any severe threat likely limited to borderline hail as main portion of shortwave is east of the area. Quite a bit of uncertainty regarding severe threat and heavy rain threat over the next 24 hours. Deepest moisture remains just offshore where dew points are in the mid and upper 70s, but drier air is over the northern portion of the area, where dew points are in the lower 60s. Next shortwave actually won't approach the area until the overnight period tonight into Saturday morning when precipitable water values will again approach 2 inches, as southerly surface winds pull moisture back into the area. Quite a bit of mid level dry air for much of the area until perhaps 06z Saturday, and would anticipate that instantaneous areal coverage during the day today should remain on the scattered side, with a significant increase in areal coverage during the mid to late evening hours. Drier air returns during the day Saturday.
Will keep the Flood Watch in place, as there was a fairly sizeable area of 1.5 to 3 inch rainfalls, and another inch or two on top of that overnight tonight could cause runoff issues.
Will not move off the NBM temperature forecast at this time, but the main question for high temperatures today will be cloud cover.
LONG TERM
(Saturday night through Thursday)
Issued at 235 AM CDT Fri May 17 2024
Upper ridging builds from Mexico into the Lower Mississippi River Valley beginning Saturday evening through much or all of the workweek. At present, it appears that any significant chance of precipitation beyond tomorrow morning is likely to wait until beyond the end of the forecast package, with at least some potential to remain dry through next weekend. Temperatures are expected to remain above normal through the forecast period.

Most forecast terminals VFR at issuance time, although thunder still being reported in the vicinity of most. Should see TSRA end at most terminals in the next hour or two, but expect ceilings to deteriorate to MVFR or IFR prior to sunrise. MVFR ceilings may remain at most terminals for much of the daytime hours. Main question during the day will be how much, if any, convective activity occurs. Most of the model guidance indicates convective development primarily beyond 00z Saturday, with some holding it off beyond 06z.
MARINE
Issued at 235 AM CDT Fri May 17 2024
Small Craft Advisory is already in place through tonight, which may be a bit overdone during the overnight period, but would prefer not to get into a situation of lowering it to Small Craft Exercise Caution and having to re-invoke an Advisory. Day shift can lower it this afternoon if it still appears that overnight winds will remain below advisory criteria. Beyond the first 24-30 hours of the forecast, a quieter wind and sea state appears to be in the cards.
