PROBABILISTIC HYDROLOGIC OUTLOOK

NATIONAL WEATHER SERVICE GOODLAND KS

843 AM MDT TUE JUN 24 2025



In Table 1 below...the current (CS) and historical (HS) or normal

probabilities of exceeding minor...moderate...and major flood stages

are listed for the valid time period.



CS values indicate the probability of reaching a flood category

based on current conditions.



HS values indicate the probability of reaching a flood category

based on historical or normal conditions.



When the value of CS is more than HS...the probability of

exceeding that level is higher than normal. When the value of CS is

less than HS...the probability of exceeding that level is lower

than normal.

These long-range probabilistic outlooks contain forecast values that

are calculated using multiple season scenarios from 30 or more years

of climatological data...including current conditions of the

river...soil moisture...snow cover...and 30 to 90 day long-range

outlooks of temperature and precipitation. By providing a range of

probabilities...the level of risk associated with long-range planning

decisions can be determined. These probabilistic forecasts are part

of the National Weather Service's advanced hydrologic prediction

service.



Visit our web site weather.gov/gld for more weather and water

information.



The next outlook will be issued around July 25th.
