NWS St. Louis, MO wrote its last area forecast discussion before the first event at Jun 14, 2:55 PM CST, 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 355 PM CDT Sun Jun 14 2015 .SHORT TERM: (Through Late Tonight) Issued at 350 PM CDT Sun Jun 14 2015 Diurnal heating of the very moist air mass across the region has yielded SBCAPES of 2000-2500 J/KG this afternoon and scattered to numerous showers and thunderstorms. Anomously high water content with PWs above 90th percentile at 1.8+ inches is resulting in very efficient rainfall production and have seen a few reports of rates in excess of 4 in/hr, however longevity has been only on the order of less than 30 minutes given scattered converage. There are no evident upper level features aiding current storms, thus expect them to follow a strong diurnally driven cycle with converage rapidly decreasing early this evening. From the later evening into the overnight hours have dramatically reduced pops the southern half of the CWA and highest in the chance range across the northeast third of the CWA along the periphery of the stronger southwestly and slightly confluent low level flow. Glass .LONG TERM: (Monday through Next Sunday) Issued at 350 PM CDT Sun Jun 14 2015 A very wet pattern is still in the offing for the upcoming week with the best apparent time frame for widespread heavy rainfall in the Tuesday-Wednesday Night time frame. A sw-ne oriented cold front will be enroaching on the northern CWA on Monday afternoon and slowly progessing southward Monday night into Tuesday when best indications are it will become quasi-stationary bi-secting the CWA. Meanwhile during this same time frame, a steady series of weak disturbances within the sw flow aloft on the periphery of the upper level high, combined with the moisture rich/buoyant air mass across the region and the front will result in increasingly widespread showers and thunderstorms. Instability and deep layer shear across the region on Monday afternoon and early evening will be sufficient for possible pulse storms and multicell clusters with a damaging wind threat, while the high moisture content will continue to support heavy downpours. Will probably eventually need a flash flood watch in the aforementioned Tuesday-Wednesday night period. Unknown is the impact of current TD#1 near the Yucatan. Models diverge on the speed and location but the general consensus is this will strengthen and track NW into TX then track north with the remnant low moving northeast along the periphery of the upper high centered in the southeastern U.S.. A general range of solutions has the center generally moving across southeast MO and southern IL on Thursday with greatest impacts along and to the right of the center. High level moisture however will provide a boost to the already high H2O content in the midweek time frame and the aforementioned heavy rainfall potential. Glass && .AVIATION: (For the 18z TAFs through 18z Monday Afternoon) Issued at 1114 AM CDT Sun Jun 14 2015 Overall pattern remains the same although any remants of a surfae have moved north of the area, along the MO/IA border with a continued northward movement. Fairly strong short wave kicking north from the TX panhandle may provide a little extra upper air support the next 24 hours. Radar shows scattered TSRA already forming across MO. VCTS for the most part with tempo's as the rain approaches a terminal. GFS beings precip back to almost all of north MO from 06 12z. THe NAM also but more of a St. Joe to Kirksville line. May put a VCTS in UIN about 08z to cover this possibility. Specifics for KSTL: Pretty much more of the same. Scattered TSRA already developing across MO so at least a VCTS will be in the terminal at issuance time. Will add tempo's as the rain approaches. Looks like most of the overnight chances will be north of STL so will leave it dry after about 03z. For now will bring in a VCTS again for Monday afternoon. A front begins moving into the state Monday afternoon so that my become the focus down the road. JPK && .LSX WATCHES/WARNINGS/ADVISORIES: MO...NONE. IL...NONE. && WFO LSX
