Kentucky Drought Monitor

The Kentucky Drought monitor is a subset of the United States Monitor, issued every Thursday morning, based on drought conditions the previous Tuesday. The map below shows the current drought level around the state, and the percent of Kentucky land area in each drought level compared to the previous week.

HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE PADUCAH KY
1015 AM CST THU MAR 6 2014

...Spring Flood and Water Resources Outlook Number 2...

This outlook is for the NWS Paducah service area. It covers the time
period for late February through late May. It includes the mid-
Mississippi and lower Ohio Rivers and their tributaries for southwest
Indiana...southern Illinois...west Kentucky and southeast Missouri.

...Flood Outlook Highlights...

Flood potential remains average or near normal for this time of year.
Minor flooding is expected. Flooding in this region occurs mainly 
due to conditions of ground moisture...river flows...and expected 
precipitation. Ice jams are rarely a factor in flooding in this part 
of the country. Most flood events in this region are due to heavy 
spring rains.

...Current Conditions...

Snow...Frost and Soil Conditions...A warmup last week caused a lot 
of the snow in the upper parts of the Mississippi and Ohio River 
Valleys to melt. A storm earlier this week produced minor additional 
amounts upstream but left the local area with a broad swath of 2 to 
4 inches of snow and sleet with isolated higher amounts from the 
Missouri bootheel to Hopkinsville. 

Soil moisture in the Mississippi Valley is below normal for this 
time of year while near or slightly above normal in the Ohio Valley. 
Reservoir levels are near normal.

In the upper parts of the Mississippi River basin there is still 6
to 24 inches of snow with a water equivalent of 1 to 4 inches. In the
upper parts of the Ohio River basin there is generally only a few 
of inches of snow with a water equivalent of 1 to 2 inches.

Streamflow conditions are near to below normal across most of the 
area with the exception of west Kentucky where rivers are running at 
or slightly above seasonal normals.

Seasonally, winter was cold with precipitation totals with an inch 
or two of normal. Average temperatures from December through 
February were 3 to 5 degrees below normal. Precipitation was more 
variable ranging from 2 inches below to a little over one inch above 
normal in most locations. Snowfall has been a little above normal, 
especially when compared to recent years.

...Probabilistic Outlooks...

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.

...Weather Outlooks...
More tranquil weather is expected in the short term with only slight 
chances for rain in the coming week. Temperatures should moderate 
allowing snow and ice to melt.

The 8 to 14 day outlook for March 13 through 19 is for below normal 
temperatures and below normal precipitation. During this time, 
normal average temperatures are in the middle to upper 40s and 
rainfall during this time period is between three-quarters of an 
inch and one inch.

The outlook for March is for climatological conditions for
temperatures and precipitation, meaning equal chances of above,
normal and below normal conditions. Normal precipitation for March is
between 4 and 4 1/2 inches.  The seasonal outlook for March through
May calls for normal temperatures and above normal precipitation.
