Probabilistic Hydrologic Outlook National Weather Service Kansas
City/Pleasant Hill MO 1100 AM CST Thu Feb 29 2024
...2024 Spring Flood and Water Resources Outlook Number 2...
This Spring Flood Outlook is for the Kansas City/Pleasant Hill
Hydrologic Service Area (HSA) which includes the Kansas River,
Missouri River, and their tributaries, in northeast Kansas and
northern Missouri.
...Below normal flood potential through May along the Missouri River
from the Iowa border through Boonville...
...Tributaries which typically flood during the spring months will
likely experience minor to moderate flooding...
Outlook:
Through May, the probability of flooding along the Missouri River
from the Iowa border to Boonville is roughly 25 to 40 percent lower
than normal.
Spring minor flood probability values along the Missouri River from
the Iowa border downstream to St. Joseph, Missouri range from 20 to
30 percent. The stretch of the river from Leavenworth, Kansas
through Kansas City has a 10 to 20 percent chance of minor flooding
through May. Further downstream, Napoleon through Boonville show
probabilities of exceeding flood stage ranging from 50 to 55 percent.
Minor flooding is likely across tributary creeks and rivers which
typically experience flooding each spring. In addition, the
following basins have greater than or equal to 50 percent
probability of reaching moderate flood category: Upper Stranger,
Crooked, Wakenda, Grand from Chillicothe through Sumner, Blackwater,
and Big. All of these basins frequently experience moderate flooding
each spring.
Recent Conditions:
The majority of the Kansas City/Pleasant Hill HSA received below
normal precipitation the past 30 days. Most locations north and east
of a line from Atchison, Kansas through Kansas City, Missouri to
Sedalia, Missouri received less than 25 percent of normal
precipitation. Liquid precipitation amounts ranged from less than a
tenth of an inch across northwest Missouri to around an inch and a
half across east-central Kansas. The bulk of the region received
between a tenth and half inch during the past 30 days. During the
past 90 days, the vast majority of the local region received above
normal precipitation. Over half of the Kansas City/Pleasant Hill HSA
received between 125 and 150 percent of normal precipitation.
30-day mean temperature values ranged around 40 across far northern
Missouri to the middle 40s from east-central Kansas into central
Missouri. These values were 9 to 12 degrees above normal. For the
past 90-Day period, mean temperatures were also above normal with
values ranging 3 to 6 degrees warmer than average.
Present Conditions:
The latest U.S. Drought Monitor indicates around 80 percent of the
Kansas City/Pleasant Hill HSA is experiencing at least abnormally
dry conditions. In addition, around 10 percent of the HSA is
affected by moderate drought. Looking at the entire Missouri Basin,
around 65 percent of the basin is experiencing at least abnormally
dry conditions with roughly 25 percent reporting at least moderate
drought, and 7 percent severe drought.
Minimal snow cover is present across the local region. In addition,
much below normal snowpack is common across the northern Plains and
mountainous areas of the upper Missouri Basin.
7-Day streamflow values across the local region indicated below
normal streamflow conditions were increasing in coverage during the
past two weeks.
Future Conditions:
7-Day forecast precipitation amounts are expected to be less than a
quarter inch with above normal temperatures likely. The outlook for
the 8 to 14 day period indicates a pattern favoring above normal
temperatures and above normal precipitation.
Looking at the outlook period through May. There is no clear signal
regarding temperature for the local area. The greatest likelihood of
above normal temperatures will be across the northern third of the
United States. The precipitation outlook slightly favors above
normal amounts across the NWS Kansas City/Pleasant Hill HSA.
The final spring flood outlook will be issued on March 14.
--------------------------------------------------------------------
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
