Area forecast discussion, Jun 10, 11:57 AM CST, 2 hours 23 minutes before
AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE ST LOUIS MO 1257 PM CDT Tue Jun 10 2014 .SHORT TERM: (Through Tonight) Issued at 233 AM CDT Tue Jun 10 2014 Focus thru this period will be precip. Main question for POPs will be pinning down the timing and location of precip thru tonight. Ongoing precip will continue to move nwd early this morning and shud only be impacting the nrn tier or two of counties of the CWA. After sunrise, this area of precip shud continue moving nwd and begin to dissipate as low level forcing weakens. By mid day, believe there will be enuf breaks in the clouds to allow insolation. This shud quickly allow TSRA to develop just ahead of the sfc low which will continue thru the afternoon. The threat for TS shud diminish quickly with sunset as the boundary layer decouples and low levels warm. Expect a def zone to reform over nern portions of the CWA as the low pulls newd out of the region. As for temps thru the period, have made only minor changes to the prev forecast, trending twd the cooler MOS. Going forecast may be too cool for the srn half to third of the CWA. However, confidence is not high enuf to raise temps attm due to expected rapid increase in cloud cover by late morning. With the widespread rainfall last night and expected thru tonight, believe patchy FG will be likely across much of the area. However, the local WRF suggests a stratus event across the nrn third or so of the CWA with boundary layer mixing continues thru the night as the sfc ridge builds into the area. Tilly .LONG TERM: (Wednesday through Monday) Issued at 322 AM CDT Tue Jun 10 2014 Not much change from the prev forecast thru this period. Mdls are in relatively good agreement thru the entire period. A s/w approaching the NW coast this morning is progd to bring a cdfnt and TSRA to the region on Thurs. A lot of questions remain regarding how much precip the region will receive with this fnt as an MCS will probably develop across the cntl Plains and move ssewd on Wed into Thurs, pushing the sfc low and forcing with it. Still, can not rule out isod to sct TSRA with the fnt and therefore kept low POPs going for now. After a rather large sfc ridge builds into the region, the next chance for precip will be Sun into Mon as a trof sets up over the wrn U.S. allowing SW flow over the region with a quasi-stationary fnt lingering across the area. Mdls differ exactly where this fnt will set up and how it behaves as a result of the convection. With the upper ridge building into the region, believe the fnt will remain largely across the nrn portions of the CWA or even further N across IA, but some storms may drift further S and have kept chance POPs going for now. Not too much change in temp forecast thru the period either. Kept seasonally cool temps going thru the end of the week. With mdls suggesting height rises across the area by Sun and Mon, have gradually warmed temps thru this period. Tilly && .AVIATION: (For the 18z TAFs through 18z Wednesday Afternoon) Issued at 1242 PM CDT Tue Jun 10 2014 KCOU and KUIN have struggled to improve from IFR thus far today thanks to wrap-around showers and low cigs associated with a surface low over southwest Missouri. This low will lift northeast this afternoon and this evening across the St. Louis metro area along the quasi-stationary front in place across the region. Metro TAF sites have managed to improve to VFR at issuance time, though feel this improvement will be short-lived as showers once again overspread the area ahead of the low, along with thunderstorms this afternoon thanks to destabilization that has occurred due to breaks in the cloudcover, and additional lift that will be provided by the aforementioned low as it moves northeast. There are already showers and thunderstorms moving northward over central and southeast Missouri, so feel that activity should become fairly widespread over the next couple of hours, with the best chance for thunder at area terminals during the late afternoon and early evening. Some small hail will be possible with some of the stronger storms. Expect thunderstorms to wane after sunset due to a loss of heating and also due to the low lifting out of the area, though some lingering light showers/drizzle may stick around through at least midnight. Despite the precipitation gradually ending, ample boundary layer moisture tonight and light/variable winds will allow fog to develop, thus expect IFR conditions to once again set in across the area tonight, before gradual improvement can occur toward the end of the forecast period on Wednesday. Specifics for KSTL: Improvement to VFR expected to be short-lived this afternoon as showers and thunderstorms are expected to overspread the area. Currently expect the best window for thunderstorm activity for KSTL to be between 21Z and 00Z this afternoon/this evening thanks to a combination of diurnal destabilization and the surface low moving northeast across the metro area. Small hail will be possible with some of the stronger storms. Expect activity to gradually wane later this evening as the low lifts northeast, though lingering light showers/drizzle may impact the terminal through the night. Also expect a return to IFR conditions due to ample boundary layer moisture and stratus wrapping around the back side of the low, which should gradually improve through the day on Wednesday.
