Discussion

A mid/upper ridge axis extended from the Lower Mississippi Valley area NNW across the Central Plains while a stationary front was bisecting Kansas early this afternoon. Low clouds and fog were observed north of the front impacting much of northern and western Kansas. This frontal boundary is progged to meander over the area through tonight before mixing northward as we move into the day on Friday. This is expected to result in another round of low ceilings and areas of fog developing along and north of the boundary again tonight. We may also see a sharp temperature gradient, especially where low clouds persist. Some elevated showers and thunderstorms will be possible across parts of central and northeast Kansas this evening and tonight, aided by a developing LLJ. PWATs are progged to rise to 1.25+ inches supporting efficient rainfall. We could see a strong storm or two with gusty winds and hail given elevated CAPE above 1500 J/KG this evening. The initial development could be over central KS before the activity focuses further north across northeast KS where we will see a higher potential for some pockets of excessive rain.

A brief lull is expected late tonight in early Friday over southern KS while some storms linger across northeast KS early on Friday. Increasing probabilities for rain will return as we move through the day as a negatively tilted shortwave trough lifts northeast towards the area. With steep mid-lvl lapse rates progged early in the period, some embedded thunderstorms are also possible at times, especially across northern KS later in the day. Some drier air could be wrapped in southeast KS, limiting rainfall as we move into the evening and overnight hours as the system quickly lifts north of the area. Some low pops were maintained on Sat but lingering clouds should keep temperatures near climate normals with highs mostly in the 60s.

Shortwave ridging will return to the area on Sunday with mostly dry weather conditions anticipated during the day. With some breaks in the clouds, afternoon highs may rise into the lower 70s in some areas while parts of central and western KS will see more seasonable highs in the 60s. Another robust mid/upper trough is progged to build over the Rockies late Sunday/Sunday night. Showers and thunderstorms are expected to become more numerous Sunday night as the exit region of the upper jet builds over the Southern Plains. The pattern may support a few strong/severe storms as we move through the day on Monday but given the potential for more widespread activity and potential training, pockets of heavy rain may be a bigger concern. High pops were maintained Mon night into Tuesday as numerous showers are anticipated under the upper low. A cold front will usher in more seasonable air as we move into Wed-Thu with highs in the low to mid 60s. Some low pops were maintained on Wed due to uncertainty in the timing of the mid/upper trough. Dry weather conditions are expected to return by late Wed into Thu.

Concerns: 1) MVFR in NC KS then LIFR again after 6Z 2) Showers move in gradually close to end of period

A stalled front is expected to have minimal movement which means there very well will be a repeat for late tonight into early Friday morning for lower clouds and fog potential across north central Kansas. Otherwise MVFR conditions are anticipated to persist for KGBD, KRSL and KSLN. KHUT is on the edge of the cloud cover which cleared out then built back in. The thought is that there will be improvements this afternoon then build back in Friday morning.

Rain showers with scattered thunderstorms will gradually move in from the south on Friday. There wasn't a mention put in for now but will be with upcoming issuances as the highest chances are from 21-7Z.
