Area Forecast Discussion
National Weather Service North Platte NE
1234 PM CDT Wed Jun 2 2021

.SHORT TERM...(Today through Thursday)
Issued at 303 AM CDT Wed Jun 2 2021

The main focus in the short term is the chance for isolated
thunderstorms this afternoon/early evening. 

An upper level trough will extend from the Great Lakes southwest
into north Texas. Northerly flow aloft will exist across Nebraska.
This afternoon, an area of 0-3km most unstable capes from 500-900
J/kg will extend across areas east of Ainsworth, North Platte and
Hayes Center. 850-700mb lapse rates will be near 9C/km. These
areas can expect a slight chance for showers and thunderstorms
developing 19Z, lasting until 01Z. Coverage looks isolated and a
few storms could become briefly strong. Highs today will mainly
range in the upper 70s, with low 80s parts of the northeast 
Sandhills. 

Tonight, a thermal ridge will develop across the Central and
Northern High Plains. 850mb temperatures across western NE will
warm to 17-19C with a light southwest wind developing. Expecting a
fairly strong inversion in the low levels with lows from the low 
to mid 50s. 

Thursday, the upper ridge across the western U.S will build into
the region. This will signal a strong warmup into the mid to upper
80s which will be 5 to around 10 degrees above normal. Dry
conditions and mostly sunny skies expected. 

.LONG TERM...(Thursday night through Tuesday)
Issued at 303 AM CDT Wed Jun 2 2021

The upper ridge will flatten out from the Desert Southwest into
the Central Plains on Friday, with most highs near 90, and even
near 95 at Valentine. 

On Saturday and Sunday, the northern stream will extend from the
Pacific Northwest and Northern Plains, while a weak closed low
remains across TX into OK. Very warm temperatures will persist
with highs 90 to 95 Saturday and upper 80 to around 90 Sunday. A
weak surface trough Sunday afternoon could trigger a few storms
late Sunday afternoon/evening across eastern areas. However, 
chances look too low for any mention at this time. 

Monday into Tuesday, upper ridging will build slightly along with
an increase in dewpoints as southerly breezes transport Gulf
moisture into the region. Highs 85 to 90. There will also be a
slight chance for thunderstorms.
