NWS St. Louis, MO wrote its last area forecast discussion before the first event at Jun 26, 12:06 PM CST, 2 hours 24 minutes earlier.
Area Forecast Discussion...Updated Aviation National Weather Service Saint Louis MO 106 PM CDT SUN JUN 26 2016 .SHORT TERM... (Today and Tonight) Issued at 306 AM CDT Sun Jun 26 2016 Like yesterday, the main focus today will be on convective trends and coverage. The vast majority of convection thus far this morning is centered through IA, with a small trailing portion in NW MO which has actually shown a recent weakening trend. This activity/MCS is being largely driven by a weak low amplitude disturbance and 30+ kt southwesterly LLJ. I'm not sure whether anything will bodily move into NE MO this morning, however there is a rather apparent outflow progressing to the east/southeast and this boundary combined with the LLJ should be enough to support at least some scattered activity within the NW third of the CWA through around 15z or so. The other quandry this morning is what will happen across southeast and east central MO into southwest IL. The overly wet GFS and some iterations of the HRRR have showers and thunderstorms developing in this region between 10-12z. While I can't totally discount this solution there is currently a severe lack of clouds where the activity is expected to evolve. Additionally the 10 member NCAR short-range ensemble has only 1 member with any development and it is rather meager. At this point I will carry some slight chance pops thinking some spotty development is at least possible. Otherwise it will be another hot and humid day with afternoon heat indices in the 100-103 range across parts of eastern MO into southwest IL. The main action is expected this afternoon. Morning clouds that exist should thin and this should promote good heating and a moderately unstable and uncapped air mass along and ahead of an advancing cold front. The combination of convergence/lift with the front and a more NE-SW oriented pre-frontal trof should lead to the development of scattered to numerous thunderstorms from central MO into central IL between 19-21z, with the activity shifting to the south-southeast through the late afternoon and evening hours along and ahead of the advancing boundaries. Southern MO and southern IL will remain the primary area for precipitation for the remainder of tonight. Can't quite figure out the NAM with all its precipitation across northern MO but the main boundary will reside to the south. Glass .LONG TERM... (Monday through Saturday) Issued at 306 AM CDT Sun Jun 26 2016 The initial front will continue to ooze south of the CWA on Monday however the air mass remains quite warm in its wake and we should see another seasonably hot day, albiet with less humidity. A secondary cold front will then begin pushing into northern MO and central IL in the afternoon advancing south of the area on Monday night. Cooler and drier conditions will then prevail Tuesday and Wednesday as a prominent surface high builds southward through the central U.S.. An amplified upper air pattern will be in place at midweek featuring a rather broad, deep upper trof over eastern NOAM and upper ridge centered through western NOAM. The long wave pattern remains status quo through the end of the week and into the weekend with and northwest flow aloft dominating. Temperatures should remain at or below average for late June-early July. We will have to closely monitor a series of short waves within the northwest flow Wednesday into Friday and potential impacts to MO and IL. At this time it appears the first several in the series will mainly impact parts of the central Plains into western MO. A stronger short wave and attendant front will bring perhaps the best threat of showers and thunderstorms in the Friday/Saturday time frame. Glass && .AVIATION... (For the 18z TAFs through 18z Monday Afternoon) Issued at 1243 PM CDT Sun Jun 26 2016 Primary concern continues to be thunderstorms this afternoon into the early evening. The primary threat area is expected to be along and south of the I-70 corridor. Most likely scenario is that the current storms southeast of Kansas City and southwest of St. Louis will continue to strengthen and become more widespread as the afternoon progresses. Some strong storms with wind gusts in excess of 35kts are possible Storms should begin dissipating by 01-02Z and think there will only be isolated to widely scattered showers by 06Z...primarily over the eastern Ozarks. Some guidance is hinting at late night fog...but am not very confident in fog development so have not mentioned it in TAFs at this point. Elsewhere and otherwise, expect VFR conditions outside of thunderstorms. Specifics for KSTL: Expecting thunderstorms currently moving into central Missouri to increase in coverage and continue moving east into the vicinity of the terminal late this afternoon. Some strong storms with wind gusts in excess of 35kts are possible. The storms should continue moving east into early evening and should also dissipate as we lose daytime heating. Some guidance is hinting at late night fog...but am not very confident in fog development so have not mentioned in the Lambert TAF. Otherwise expect VFR conditions outside of thunderstorms.
