Thunderstorms currently erupting across central KS into northern OK
are anchored by boundaries in their vicinity. Localized moisture
pooling, an uncapped and unstable atmosphere, and steep lapse rates
are all contributing to the upscale growth this afternoon. While some
of these parameters bleed into the western portions of this forecast
area, the local atmosphere is drier, and without much for storms to
hang their hats on, chances of storm development and/or maintenance remains
low. Additionally, a lack of deep layer shear and a large-scale
lifting mechanism keeps storm growth spatially and temporally at bay.
Note though that the chances of pop-up pulsy storms are not nil -
they just remain on the low side.
Better convection chances arrive late tomorrow through early
Wednesday. While the area has had a bit of a break from the unsettled
pattern this weekend, a few more days of unsettled weather returns.
Surface southerly flow returns for Memorial Day and coupled with
another unstable atmosphere and steep lapse rates during the
afternoon, storms will be possible. However, 0-6km shear remains
marginal at best for organized development and severe potential so
the storm mode of choice will likely be pulsy in nature. As a frontal
boundary and upper-level trough approaches the area late Tuesday,
storm organization as well as coverage will be on the increase. Shear
will remain in question with respect to severe chances though.
For the latter half of the week, should finally see a decent period
of dry weather as surface high pressure visits the area. The next
chance for precip could arrive next weekend as a boundary and
seemingly weak trough axis rotates through but the limiting factor
could be moisture. Too far out at this point to linger on the details
at this point. Temperatures will be rather seasonable for this time
of year, ranging in the 70s and 80s throughout the forecast period.

VFR conditions will prevail tonight through much of the day Monday
with occational mid and high level clouds moving across. However,
towards the later periods of Monday afternoon and into Monday
evening, thunderstorms may develop across eastern Kansas and western
Missouri. Otherwise, expect surface winds to remain from the south
overnight and through Monday.
