Area forecast discussion, May 22, 5:48 PM CST, 2 hours 45 minutes before
AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE ST LOUIS MO 648 PM CDT Thu May 22 2014 .SHORT TERM: (Through Late Tonight) Issued at 335 PM CDT Thu May 22 2014 Convection continues to increase slowly over eastern KS in advance of ill-defined shortwave. Expect this activity to track E-SE into the evening hours, working across mid MO/Ozarks and then tracking into SE MO, with activity then weakening late this evening with passage of shortwave and loss of daytime heating. Have continued some low PoPs after 06z which may be a bit overdone, however models do suggest some very weak shortwave energy breaking through ridge and trickling into the area during the predawn hours. Very narrow W-E band of showers draped across northern parts of the CWA attm should dissipate heading into the early evening hours as stronger convection develops over western and central MO. Still a bit unsure of where the northern edge of this primary area of convection will set up, but for now have pretty much maintained going forecast trends and gone with chance PoPs as far north as a KMJY-KSTL-KMVN line for this. Truett .LONG TERM: (Friday through Next Thursday) Issued at 335 PM CDT Thu May 22 2014 The threat for convection on Friday should be across central and southeast MO where more favorable low level moisture and instability will exist just north of the old frontal boundary. Drier and more stable conditions will be across northeast MO and IL on the southwestern periphery of the surface ridge moving slowly southeastward through the Great Lakes region. An easterly surface flow will bring lower surface dewpoints into this area Friday night leading to cooler low temperatures which should be at or slightly below normal for late May. The chance for showers/storms will continue across central and southeast MO on Saturday as weak shortwaves move east northeastward through the region, trying to break down or weaken the mid-upper level ridge over the area. Surface winds will become southerly on Sunday bringing warmer and more humid air into the region. The models generate more qpf across MO Sunday afternoon with better low level moisture and instability across this area. The models continue to generate showers and storms across our forecast region on Memorial Day as weak shortwaves are ejected east northeastward ahead of the slow moving upper level low moving into the Plains, and breaking down the mid-upper level ridge over our area. The GFS model sags a cold front southward into our forecast area Tuesday and Tuesday night as the upper level low weakens and moves southeastward through the southern Plains. The latest ECMWF model does not appear to bring this front southward into our forecast area, but is further north with the track of the the upper level low bringing it into southwest MO by Wednesday. The ECMWF model has convection ahead of this feature as it moves it very slowly eastward through southern MO. With plenty of model uncertainty will just include chance pops for much of the area for Tuesday through Thursday. GKS && .AVIATION: (For the 00z TAFs through 00z Friday Evening) Issued at 647 PM CDT Thu May 22 2014 Area of showers and isolated thunderstorms across northern MO and west central IL is expected to weaken as it shifts to the south the next few hours. Have left the St. Louis metro TAF sites dry for now. Additional storms are expected to develop the next few hours from central into southeast Missouri, so will leave the VCTS at KCOU. MVFR conditions are possible with the heavier cores. The cold front has moved south of the area and is expected to through the period. Dry and VFR conditions are expected. Specifics for KSTL: Area of showers and scattered thunderstorms north of terminal are expected to dissipate. Otherwise dry and VFR conditions are expected next 30 hours.
