Little changes needed as forecast on track with temps already into
the low to mid 80s north where a few CU have developed. Mid level
lapse rates remain stable suppressing shower chances will monitor
how the CU field evolves this afternoon to see if lapse rates
steepen and showers can form in the LOTW region.

.SHORT TERM...(Today and tonight)
Issued at 314 AM CDT Thu Jun 21 2018

A near carbon copy of Wednesday for today. Light winds all day as
a weak high pressure ridge moves over the Red River valley. 500 mb
low in SW Iowa will send high level moisture northwest across the
area, but thin enough to allow for sunshine to filter through
especially in far NE ND and NW MN. This area highs will be the
warmest with upper 80s once again with rest of the area 80-85. 925
mb temps about 2-3 deg warmer today than on Wednesday. Light south
winds tonight with high clouds and lows mostly lower 60s.

.LONG TERM...(Friday through Wednesday)
Issued at 314 AM CDT Thu Jun 21 2018

The upper level will be in transition with primarily a split flow
regime to start the extended period. The southern stream is expected
to set up over the central plains with impulses propagating through
the flow. This pattern continues through the weekend and into early
next week with showers and thunderstorms possible as the impulses
cross the area.

The pattern begins to shift by mid week with a broad upper level
trof lifting a bit farther north over the northern Rockies and
norther Plains. A system will cross the area which will help
increase precipitation chances. Otherwise...little change is
forecast to high temperatures...which are expected to remain in the
low to mid 80s through the end of the period.
