Hail in Nebraska, June 13, 2018

Area Forecast Discussion
National Weather Service North Platte NE
618 AM CDT Wed Jun 13 2018

.SHORT TERM...(Today and tonight)
Issued at 335 AM CDT Wed Jun 13 2018

For Wednesday...thunderstorms will be the main story across much of
the forecast area. The best chance for thunderstorms will be late
morning and early afternoon. Current thinking is that severe threat
is low. However, the latest SPC guidance has included locations west
of US-83 in a marginal risk. Therefore, the potential is there for
some storms to reach severe criteria. By Wednesday evening, the
thunderstorm potential will have shifted east and locations east of
US-83 will have a chance to see a thunderstorm as well as some much
needed rain. Heavy rain and localized flooding is not expected as
these storms will be fairly fast moving and only a tenth or two of
new rainfall is expected. With rain and clouds present much of the
day, temperatures will remain on the cooler side once again. Overall
highs will only rise into the low to mid 80s by Wednesday afternoon.

All storm potential will have moved east of the forecast area by mid
evening as high pressure begins to build back into the area.
Overnight low temperatures drop into the low 60s.

.LONG TERM...(Thursday through Tuesday)
Issued at 335 AM CDT Wed Jun 13 2018

A dry start to the extended period is expected as surface high
pressure continues to build and slide across the central US. In
addition to drier weather, temperatures are also expected to rebound
back into the 90s on Thursday and lasting through the weekend.
Generally, high temperatures will be slightly cooler across the Pine
Ridge region where highs only rise into the low to mid 80s.

A weak system will bring another chance of some showers and
thunderstorms to the western forecast area (west of US-83) on Friday
night. At this time severe weather chances remain low. A better
chance of storms arrives on Sunday night as a cold front drags
across central Nebraska. Have put in likely PoPs for this timeframe
as models seem to be in good agreement about this system. Severe
weather looks possible on Sunday night as warm daytime temperatures
combined with the front moving across the region and plenty of
instability will produce a favorable environment for strong storms.
Will continue to monitor this system over the next couple days.

Rain and thunderstorm chances continue into the beginning of next
week. However, shower development is still uncertain and only a low
chance PoP is warranted at this time. After the passage of the cold
front on temperatures will plummet across much of north central and
western Nebraska. Highs will only rise into the low to mid 70s on
Monday and mid to upper 70s on Tuesday. After several days of
temperatures in the 90s, this will be a welcome relief from the
heat.
