PROBABILISTIC HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE Springfield MO
900 AM CDT Wed Mar 30 2024

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/sgf for more weather and water
information.

...Current Conditions as of March 27th, 2024...

* River Levels...River levels were running generally near normal.

* Soil Moisture...Soil moisture was running near normal to below
  normal.

* Drought Conditions...Generally, Moderate Drought (D1) conditions
  existed across the northeast and Abnormally Dry (D0) conditions
  existed across much of the rest of the area. A few locations
  across far southern Missouri were not in drought conditions.

The next outlook will be issued during the last week of April.
