Area Forecast Discussion
National Weather Service North Platte NE
654 AM CDT Sun Jun 24 2018

.SHORT TERM...(Today and tonight)
Issued at 327 AM CDT Sun Jun 24 2018

A rainy end to the weekend is expected on Sunday as an upper level
low pressure system develops off the Rockies and very slowly moves
across Nebraska. The latest SPC guidance has lowered our severe risk
into the marginal risk. Despite this, severe storms are still going
to be possible on Sunday as instability increases by Sunday
afternoon and plenty of low level moisture will be present. The best
chance for severe weather will be southeast of a line from Oshkosh
to Valentine.

.LONG TERM...(Monday through Saturday)
Issued at 327 AM CDT Sun Jun 24 2018

Rain and thunderstorms continue into Monday as the upper level low
pivots over the central US. Severe potential not likely at this time
due to previous rain limiting the instability across the region.
While severe weather is not expected, heavy rain will be a concern.
Total rainfall totals will total between a half inch and one inch by
the end of Monday with locally higher amounts near 1.50 to 1.75
inches near the O'Neill area. Flash flooding could be possible,
especially over areas that are already saturated with rain from
Sunday. High temperatures will remain cool as well on Monday with
most locations only seeing temperatures in the mid to upper 70s.

Thunderstorms and rain showers will slowly taper off on Monday night
with a period of dry weather returning to the region. High pressure
builds back over north central Nebraska allowing us to dry out from
the recent heavy rain. Dry weather will continue through Friday
before isolated afternoon storms return on Saturday.

In addition to drier weather returning for much of next week,
temperatures will also rise well above average. Temperatures will
rise into the upper 80s across the north and the low to mid 90s
across the south from Tuesday through next Saturday. The warmest day
will be Thursday where afternoon temperatures will easily rise into
the 90s across the entire forecast area with the north seeing low
90s and areas south of I-80 approaching 100.

.AVIATION...(For the 12Z TAFS through 12Z Monday morning)
Issued at 654 AM CDT Sun Jun 24 2018

As an upper level low pressure system crosses the region through
tonight, scattered showers can be expected. A few thunderstorms
may also occur during the afternoon into the early evening hours
at the KLBF and KVTN terminals. VFR ceilings are forecast, while
visibilities may briefly fall below 5sm with any passing showers.
Prevailing winds should remain below 10 kts, except occasional
gust up to 20 mph with some passing showers.
