NWS Topeka, KS wrote its last area forecast discussion before the first event at Aug 9, 5:48 AM CST, 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 648 AM CDT Fri Aug 9 2013 .SHORT TERM...(Today and Tonight) Issued at 350 AM CDT FRI AUG 9 2013 A large mid-level low remains anchored north of the Great Lakes region with a broad trough stretching across much of the northern and northeastern U.S. Within this mid-level pattern, a weak shortwave trough was present over northwestern Kansas. However, models show this wave shearing out and weakening today as it slowly progresses eastward toward the area. As of 09z, a stationary front was stretched along the Oklahoma/Texas border, which is a bit further south than models had previously shown. Along and north of this boundary an MCS had developed and was being supported by decent isentropic lift. This MCS was tracking east-northeast across Oklahoma and extended northward into far southern Kansas. As a result of this front being pushed further south of the region, models are actually in good agreement in keeping these widespread showers and thunderstorms focused primarily across southern Kansas this morning. However, a narrow convergence zone has set up generally along the I-70 corridor, helping to support the development of some scattered showers around that area. In general, models have been trending better with this early morning MCS, which limits the northern extent of which these showers and thunderstorms are expected to track. Best precipitation chances within the forecast area look to be focused across east central Kansas as this activity lifts northeastward toward the area this morning. Anticipate that these showers and thunderstorms will struggle to spread further north of the I-70 corridor as surface high pressure remains in place over Minnesota and Wisconsin, resulting in light northeasterly winds and ultimately drier air advecting into northeast Kansas. As a result, expect only some scattered light showers and isolated thunderstorms over the northern half of the forecast area today as a result of that convergence zone. Have increasing PoPs across east central Kansas through the morning hours and into the early afternoon as this MCS advances into southeast Kansas. Expect this activity to quickly diminish mid to late afternoon into the evening hours as this system weakens and isentropic lift diminishes greatly. By this evening, have only slight chance PoPs focused across far east central Kansas with dry conditions likely by the overnight hours. As for temperatures, expect some breaks in the cloud cover today, especially across far northern Kansas, due to the limited amount of precipitation. As a result, have bumped high temperatures for today up a couple of degrees into the low 80s. With cloud cover gradually diminishing from northwest to southeast across the forecast area tonight, overnight lows should be on the cool side once again with temperatures dropping into the low to mid 60s. .LONG TERM...(Saturday through Thursday) Issued at 350 AM CDT FRI AUG 9 2013 The details of the mid to long term forecast remain murky due to the rather poor model performance in resolving precipitation features over the past week. Despite the general uncertainty, a few things can be forecast with higher relative confidence. The first is that the general long wave pattern will see very little change with a deep trough over the eastern CONUS, a trough off the Pacific northwest coast, and weak ridging over the Rockies. Locally, this points to a continued northwest flow pattern with occasional weak disturbances moving nearby or overhead. This should keep temperatures through the period generally in the 80s with some day-to-day variation mainly depending on cloud cover. Timing of the individual disturbances is difficult, but can say with some confidence that the periods most likely to be mainly dry across the area are Saturday into Sunday. There also appears to be a fair chance for thunderstorms to impact the area between Sunday night and Monday night as some indications suggest that the warm front tries to surge north into Kansas with a low level jet focused toward northeast Kansas. It then appears that the surface high pressure to the northeast may strengthen and push drier air back into the forecast area by Tuesday, with precip chances decreasing accordingly. The main uncertainty through the period is not if it will rain, but where it will rain. Thunderstorms are likely within 300 miles of Topeka essentially every day of the coming week, but with a drier airmass to the northeast, an ever-present frontal boundary to the south and west, and slight variations to the track of weak upper level disturbances, minor changes in the weather pattern can make the difference between dry and very wet conditions across the forecast area. Barjenbruch && .AVIATION...(For the 12Z TAFs through 12Z Saturday Morning) Issued at 647 AM CDT FRI AUG 9 2013 For the 12z TAFs, while the bulk of the heavier precipitation is expected to remain well south of the TAF sites, scattered showers could persist around the TAF sites through the morning hours and possibly into early this afternoon. This area of precipitation is expected to weaken and diminish in coverage this afternoon into this evening as it shifts southeast of the area. Winds through the period will remain light out of the northeast with mid-level clouds gradually diminishing overnight into Saturday morning. && .TOP WATCHES/WARNINGS/ADVISORIES...
