NWS St. Louis, MO wrote its last area forecast discussion before the first event at Jul 25, 8:50 AM CST, 1 hour 22 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE ST LOUIS MO 950 AM CDT Fri Jul 25 2014 .UPDATE: Issued at 950 AM CDT Fri Jul 25 2014 Complex of TSRA continues to maintain itself rather well on its backside over northeast MO and eastern IA, where lo level jet and better instability are feeding it. An isolated threat for large hail exists, but should decrease heading deeper into the morning. Overall health of TSRA complex should also begin to fail as we head into the afternoon hours, with strengthening cap of warm air to the west and weakening lo level jet. This rain should have a somewhat easier time of advecting in IL versus MO and updated the forecast accordingly, although will no doubt need to tweak expected coverage over the next couple hours. Also adjusted temps further down in IL, where readings should stay below 80F, but enough recovery expected in the west and south to maintain previous forecast. TES && .SHORT TERM: (Through Late This Afternoon) Issued at 330 AM CDT Fri Jul 25 2014 Convective trends and the extent of pops are the biggest forecast challenge today. Thunderstorms have blossomed within the last several hours across central Iowa at the terminus of a stout southwesterly LLJ, and along the eastern periphery of elevated instability, deeper moisture and steep mid level lapse rates. Short range guidance shows the LLJ slowly veering this morning, providing favorable moisture transport and forcing as the flow aloft and northwestely deep layer shear steer the activity east and southeastward. The HRRR runs since 01Z have been very emphatic supporting this scenario bringing showers and thunderstorms into northeast Missouri and west central Illinois. I have increased pops into the likely range in this area tapered to slight chances just north of interstate 70. Believe that most of this activity will be east of the MS river by early afternoon and exiting the CWA shortly thereafter. This activity will likely delay/impeed the northward retreat of the warm front, however in central MO there should be no issue where highs will be around 90. Glass .LONG TERM: (Tonight through Thursday) Issued at 330 AM CDT Fri Jul 25 2014 The warm front should have exited the entire CWA by early evening while the upstream cold frontal system will be slowly advancing and stretching from the upper MS valley into the central Plains. High heights aloft and warm mid level temperatures should suppress any surface-based storm development within the large warm sector spanning the CWA, however the area will remain subject to an elevated shower and thunderstorm threat. While there is no defined focus for thunderstorms, a westerly LLJ will be poised across the area in conjunction with steep mid level lapse rates and good elevated instability supporting a least a chance pop. These same unfocused conditions will exist on Saturday morning. The set-up should improve on Saturday afternoon. Strong surface heating should yield temperatures well into the 90s with dew points in the 70s. This will result in afternoon heat indices in the 100-104 degree range, just below advisory criteria. We will need to monitor this closely as just a bit higher dew points and/or temperatures and a heat advisory will be warranted. The aforementioned conditions along with the presence of steep mid level lapse rates will yield very unstable conditions during the afternoon/evening. There are indications that the combo of heating and a disturbance in the west northwest flow aloft should sufficiently weaken the cap allowing for robust thunderstorm development along the west-east oriented front stretching in the vicinity of far northern MO through central IL into the OH valley. How far west development occurs is uncertain but height falls/cooling aloft on Saturday night could aid this process. Deep layer shear and instability is quite favorable for organized severe with damaging winds the most apparent severe threat at this time. I have some low pops on Sunday ahead of the advancing front, but the overall threat of precipitation will be lower as compared to the Saturday night. Cooler and drier air will advect in earnest into the area on Sunday night with a large surface high settling into the Nation's midsection on Monday. An unseasonably deep upper trof over eastern NOAM through the first part of next week will keep the large surface high in control and allow for another period of below average temperatures as we exit July and head into August. Glass && .AVIATION: (For the 12z TAFs through 12z Saturday Morning) Issued at 519 AM CDT Fri Jul 25 2014 Cluster of thunderstorms over southeastern Iowa will continue tracking southeastward and will arrive at the KUIN TAF site by around 12z. VSBYS may fall to high end of MVFR range as the storms pass, but cigs will likely remain AOA 6K feet. Storms will move into more stable atmosphere as they approach the St. Louis metro TAF sites, and most model output suggests little or no precip there. With that in mind, will keep all St. Louis area TAFS dry. South winds will increase this afternoon. Specifics for KSTL: Thunderstorms approaching from the northwest should dissipate before moving into KSTL TAF site as they move into more stable air. High clouds will remain through at least midday...with south winds increasing to 10 to 14 mph by afternoon. Browning && .LSX WATCHES/WARNINGS/ADVISORIES: MO...NONE. IL...NONE. && WFO LSX
