Area Forecast Discussion National Weather Service Saint Louis MO 349 AM CDT Thu Jul 2 2020
SHORT TERM. (Through Late Friday Afternoon) Issued at 337 AM CDT Thu Jul 2 2020
In the very short term, patchy areas of dense fog and stratus will gradually lift and scatter out by mid morning. Otherwise with upper level ridge parked just to our west and an axis of vorticity entrenched north/south across forecast area, will see isolated/scattered showers and storms develop, especially from late morning and into the afternoon hours today and again on Friday. As for high temperatures, they will be near normal in the mid 80s to low 90s both days. With surface dewpoints in the low to mid 70s today, it will remain rather humid with heat indices between 95 and 100. Lows tonight will be in the upper 60s to low 70s.
LONG TERM. (Friday Night through Wednesday) Issued at 337 AM CDT Thu Jul 2 2020
Upper level ridge will weaken a bit over the region through the holiday weekend, so the Fourth of July will be a bit warmer, but remain dry for the holiday festivities. Otherwise, upper ridge looks to build back in and will allow for warmer temperatures, more humidity and diurnal chances of showers and storms Sunday through next Wednesday.
AVIATION. (For the 06z TAFs through 06z Thursday Night) Issued at 1230 AM CDT Thu Jul 2 2020
Primary concern for the rest of the night remains fog and stratus development, bringing conditions down to IFR for a good portion of the area. Lowest cigs/vsbys are still expected generally along and east of the Mississippi River, though latest guidance is now showing some IFR fog over parts of central Missouri as well. That being said, model guidance has been very consistent in developing fog and stratus along and east of the Mississippi River overnight, so confidence is high that this will occur. Expect cigs/vsbys near airport minimums along and east of the Mississippi River, this includes KUIN, KSTL, KSUS and KCPS. Visibility should improve within a couple of hours of sunrise, but ceilings will likely be slow to rise above 1,900 feet. There also continues to be a chance of thunderstorms, mainly on Thursday afternoon.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
