Area forecast discussion, Jul 3, 3:28 PM CDT, 2 hours 13 minutes before
Area Forecast Discussion National Weather Service Saint Louis MO 328 PM CDT Wed Jul 3 2019 .SHORT TERM... (Through Late Thursday Night) Issued at 327 PM CDT Wed Jul 3 2019 Thunderstorm activity, like the past couple of days, should weaken and eventually dissipate by late this evening due to the loss of daytime instability. The remnant MCV currently near the MO/KS border will continue to heat slowly to the east/northeast and this feature may have to be watched for possible additional activity overnight tonight. CAMs keep it fairly quiet associated with this feature overnight, but yet another MCV is expected to develop associated with overnight convection in eastern Kansas. This feature will propagate eastward through the day on Thursday, and could help provide a bit more focus for storms just downstream of it tomorrow across the northwestern half of the CWA. Given that this feature does not exist yet, the confidence in this scenario is not particularly high. Regardless, additional scattered storms are likely areawide due to moderate instability in an uncapped atmosphere. These storms, like today and the previous couple of days, should weaken and eventually dissipate during the evening hours on Thursday. This should provide a window of dry weather for 4th of July festivities. Little to no change in expected temperatures through the short-term forecast period. Persistence remains a very good forecast, with lows tonight and Thursday night mainly in the upper 60s to mid 70s and highs for the 4th in the mid 80s to near 90 degrees. Humidity will also remain high, so look for maximum heat index values to be in the mid to upper 90s during the afternoon. All in all, a very typical 4th of July is forecast for the bi-state area with seasonably hot/humid conditions and scattered thunderstorms in the afternoon and early evening hours. Gosselin .LONG TERM... (Friday through Next Wednesday) Issued at 327 PM CDT Wed Jul 3 2019 Summertime weather pattern will remain in place heading into early this weekend with seasonably hot/humid conditions and a chance of thunderstorms each afternoon/evening. The mid/upper level ridge begins to breakdown late this weekend allowing a slow-moving cold front to move through the CWA. This frontal passage will provide another chance of showers and thunderstorms from Friday night through early Sunday. A brief period drier and slightly cooler weather is likely to conclude the upcoming holiday week heading into possibly early next week. Flow aloft becomes more zonal however thereafter so expect temperatures to moderate back to near or just above normal along with an increasing chance for showers and thunderstorms. Gosselin && .AVIATION... (For the 18z TAFs through 18z Thursday Afternoon) Issued at 1156 AM CDT Wed Jul 3 2019 Scattered thunderstorms are likely this afternoon into the early evening hours. Any storms that directly impact a terminal will have the capability of producing gusty winds (30-40 mph most likely), small hail, and MVFR or IFR visibilities in heavier downpours. The threat for thunderstorms should wane this evening, with likely dry weather overnight tonight. Scattered storms may once again impact KCOU and KUIN Thursday morning so added a VCTS mention. Wind speeds should remain light outside of any thunderstorms or outflow boundaries, with the primary direction today likely south/southwest. SPECIFICS FOR KSTL: Thunderstorms have already developed just to the east/northeast of the terminal as of 1700 UTC. Scattered storms are likely in the vicinity of the terminal this afternoon into early this evening. Any storm that directly impacts Lambert Field will have the capability of producing gusty winds (30-40 mph), small hail, and MVFR or IFR visibilites in heavier downpours. The threat for thunderstorms should diminish this evening, with dry weather favored overnight tonight into Thursday morning. Scattered storms are forecast to redevelop midday on Thursday so added a new VCTS group to account for this next round of scattered storms. Gosselin && .LSX WATCHES/WARNINGS/ADVISORIES... MO...None.
