.DISCUSSION... Issued at 410 AM CDT Sat Jun 6 2020
 It will be significantly more humid through early
next week as dewpoints rise into the upper 60s to
lower 70s. Heat index values increase to 95 to 104
across much of the region both today and Sunday,
which will be just shy of advisory criteria.  An
upper level ridge will remain in place across the
region helping to contribute to the continued heat
wave we`ve been experiencing. Convection across
the central part of NE will move northeast this
morning, and likely weaken, with the remnants
remaining /just/ west of the forecast area this
morning. However, they could just clip our area
near the SD border by late morning and early
afternoon, then moving north into SD later today. 
Southeast winds increase into the 15-25 mph range
today, and could see gusts up to 35 mph north of
I-80. Another hot day with temperatures in the
lower to mid 90s. June 1-5 will set a record for
the hottest start to June at Omaha. This was
accomplished with no individual days setting any
maximum temperature records, but still an
impressive stretch of summer heat.  As discussed,
heat index values will be quite sultry today, but
the strong winds should help a bit in that regard.
Heat indices are forecast just below advisory
criteria, thus decided to hold off with a headline
at this time.  Nighttime convection is again
expected across central NE, and the tail end of
that could affect the NE/SD border before daybreak
Sunday. Otherwise, it`s a pretty muggy night with
lows only in the mid 70s.  Sunday will bring
similar weather to today, with southerly winds at
15 to 25 mph with gusts 30 to 35 mph. Highs again
in the mid to upper 90s, with afternoon heat
indexes just shy of advisory criteria.  More of
the same for Monday, although both temperatures
and dewpoints may be a couple of degrees cooler,
thus heat index values will also be slightly
cooler. This will also be the 8th straight day
with temperatures in the 90s for most locations. 
Regarding records, it appears that daytime max
records are probably still too high both today and
Sunday. However, the nighttime maximum mins may be
in jeopardy tonight at Lincoln and Norfolk with
the mid 70s lows.  We will see a dramatic change
in the weather by Tuesday as a cold front moves in
from the northwest. In fact, we start to see the
influence of that into northeast NE Monday
afternoon with increasing chances for rain there,
generally northwest of a line from Columbus to
Wayne. And then rain chances significantly
increase Monday night into Tuesday as the front
settles eastward. Northeast NE will also be in a
slight risk of severe weather Monday afternoon and
night. And there`s also the risk for locally heavy
rainfall in that area with up to a couple of
inches possible.  Farther east, the remnants of
Tropical Storm Cristobal will be moving up the
Mississippi River valley. All models however keep
the western edge of that moisture east of the
area, thus it likely won`t impact us. Tuesday will
however be a wet day with numerous showers and
storms, gusty northwest winds, and temperatures
sharply cooler in the 70s. The front will provide
welcome relief and some additional moisture. The
rain winds down Tuesday night, and the remainder
of the forecast will be dry and seasonable with
highs in the 70s and 80s.
