.DISCUSSION...
Issued at 124 PM CDT Mon Jun 2 2025

H5 ridging and surface high pressure will keep dry and warm
conditions in place across the region through Tuesday.
Temperatures will remain near to slightly above normal. Ongoing
high-level wildfire smoke from Canada will persist through the
afternoon into tonight, but will finally diminish by Tuesday.

A turn to unsettled weather will begin Wednesday and looks to
continue through the weekend. This will be caused by a frontal
boundary that will push southeast into the area and then stall
out from southwest to northeast through the heart of the
forecast area. This will result in a daily chance (40-80%) of
thunderstorms during this time. While the potential for severe
thunderstorms remains low/uncertain, the risk for areas of
potential flooding from training convection appears to be
increasing.

Aiding in the flooding risk will be elevated PWAT values from
the remnants of Tropical Storm Alvin in the eastern Pacific
Ocean being drawn northeast into the region ahead of the frontal
boundary. This extra moisture will allow for efficient rainfall
processes and higher totals. The latest QPF shows a broad brush
of 1.5 to 3.0" over the area between Wednesday and Sunday, with
locally higher totals up to 4.0" in southeast Missouri. While
the rainfall will be spread out over several days, the risk of
localized flooding will rise as rain continues to fall over
saturated ground. Temperatures will trend slightly lower during
this period due to clouds and rainfall coverage.
