.SHORT TERM /THROUGH SATURDAY/...
Issued at 353 AM CDT Fri May 17 2024

A quiet forecast is in store for north central Nebraska through the 
majority of the short term. Weak upper level ridging and surface 
high pressure will keep conditions quiet while warm air advection 
into the region will push temperatures into the warmer end of 
guidance today. At this time, 850 mb temperatures in the 20 to 26 
degree C range will surge into western and southwest Nebraska during 
the day today. The latest trends suggest maximum temperature 
probabilities of hitting the upper 80s to be in the 50th percentile. 
While not exceptionally high, this combined with the continued 
warming trend and surge of WAA will increase confidence of high 
temperatures to easily rise into the mid to upper 80s with some 
isolated locations across extreme southwest Nebraska hitting 90 
degrees.  

A weak trough will track across the High Plains on Friday night 
bringing some cooler temperatures to the region for Saturday. High 
temperatures will drop down into the 70s, however, dry conditions 
will persist through Saturday afternoon. Increasing clouds are 
anticipated by late afternoon in advance of the next weather system, 
but any precipitation will hold off until later on Saturday
night. &&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Issued at 353 AM CDT Fri May 17 2024


Active weather will then arrive on Saturday night bringing 
significant rain chances as well as potential severe storms to the 
region through Sunday.

A shortwave will move into the region on Saturday night bringing 
with it the potential for rain showers and isolated thunderstorms. 
Minimal instability will keep any showers and thunderstorms from 
becoming severe, however, small hail and some brief stronger winds 
will be possible through sunrise Sunday morning. A secondary 
stronger upper level trough is then expected on Sunday afternoon and 
evening resulting in another round of thunderstorms, some 
potentially severe as a better region of instability arrives by 
Sunday afternoon. There is some concern that lingering showers from 
Saturday night may limit the severe potential for later in the day 
by creating a more stable environment. However, the latest model 
runs continue to suggest two separate rounds of convection  with 
current SPC guidance supporting the potential for severe storm 
development by Sunday evening. With this system still three days 
out, details are still being fine-tuned and changes will likely 
occur over the next couple of days. Those with outside plans on 
Sunday should stay weather aware and be prepared to make adjustments 
based on the latest forecasts. 

A series of disturbances will continue to impact Nebraska through 
the end of the extended period. At this time, severe weather risk 
remains uncertain, although, it appears that heavy rain may be the 
highest risk through mid-week. Stay tuned to later forecasts as 
threats become clearer due to these mid-week systems in the coming 
days.
