SHORT TERM. (Through Late Friday Afternoon) Issued at 312 AM CDT Thu May 13 2021
The ridge axis extending from the Great Lakes region southwestward into Kansas will slowly slide to the southeast over the next 24 to 36 hours. So clear and dry conditions will prevail with slowly moderating temperatures. Highs today will be in the mid to upper 60s with lows tonight in the 40s.
By Friday, as the surface ridge slowly shifts east of the region, winds will back to the south once again. The latest HREF, as well as NAM and GFS model runs are still indicating a warm front will develop across northern Kansas into central Missouri with a complex of showers and storms developing on the nose of a 35 to 40 kt low level jet over eastern Nebraska late tonight. The complex will slide southeast into portions of central and northeast MO as well as west central IL, as it weakens by Friday afternoon.
LONG TERM. (Friday Night through Wednesday) Issued at 312 AM CDT Thu May 13 2021
Even though an active weather pattern sets up through next week, there will be plenty of dry time with temperatures near normal.
By Friday night, another warm front develops, extending from a surface low over eastern Colorado eastward along the Missouri/Arkansas border. However, the exact location of the front is hard to pin down as the ensemble and deterministic models have differing solutions on its location. Otherwise it will be another wet period as an MCS develops over eastern Kansas on the nose of a 30kt+ low level jet and slides east along the front on Saturday before weakening.
By Saturday night, the warm front will become nearly stationary across our forecast area. It will be a focus for several more rounds of showers and storms through next week as we remain in a persistent moist southerly low level flow. The moisture combined with low-mid level warm air advection ahead of relatively weak shortwaves will result in convective initiation along and just north of the front through next Wednesday, especially late Saturday night through Sunday.
AVIATION. (For the 12z TAFs through 12z Friday Morning) Issued at 603 AM CDT Thu May 13 2021
VFR flight conditions through the forecast period with light and variable winds. Could see some diurnal cu develop over the St. Louis metro area after 17z today, then dissipate by 00z Friday, so added mention to KSTL and KCPS TAFs.
