A VERY ACTIVE SPRING WEATHER PATTERN WILL CONTINUE ACROSS THE

HEAVY RAINFALL THAT MAY LEAD TO FLASH FLOODING. AN ENHANCED RISK
FOR SEVERE WEATHER IS FORECAST FOR MUCH OF KANSAS TODAY WITH A
BROADER SLIGHT RISK SOUTHWARD TO PARTS OF OKLAHOMA AND NORTHWARD

CHANCES FOR A FEW TORNADOES ACROSS KANSAS. ON MONDAY, THE THREAT
SHIFTS EASTWARD TO THE MIDDLE-MISSISSIPPI VALLEY, INCLUDING STATES
SUCH AS IOWA, MISSOURI, AND ILLINOIS. LARGE HAIL, STRONG TO SEVERE
WINDS, AND STRONG TORNADOES ARE POSSIBLE. AN ENHANCED RISK IS
FORECAST ON MONDAY WITH A 45 % RISK OUTLINED FOR DAMAGING WINDS
ACCORDING TO SPC. STAY WEATHER AWARE AND HAVE A WAY TO RECEIVE

IN ADDITION TO SEVERE WEATHER, THE RISK FOR FLASH FLOODING WILL
ALSO BE PRESENT. WARM AND MOIST AIR IN THE SOUTHERN PLAINS WILL
ADVECT NORTHWARD WITH A STRENGTHENING AREA OF LOW PRESSURE.
FRONTAL BOUNDARIES WILL INTERACT WITH THE UNSTABLE AIR MASS AND

MONDAY. FOR TODAY, MULTIPLE ROUNDS OF STORMS COULD IMPACT EASTERN
KANSAS, WESTERN MISSOURI, AND SOUTHERN IOWA AND NEBRASKA. A SLIGHT
RISK FOR EXCESSIVE RAINFALL IS IN EFFECT FOR THESE REGIONS. 2-3
INCHES OF RAIN COULD FALL, WITH SOME AREAS SEEING LOCALLY HIGHER

EXCESSIVE RAINFALL. TURN AROUND, DON'T DROWN. ON MONDAY, THE FLASH
FLOOD THREAT SHIFTS EASTWARD TO EASTERN IOWA AND NORTHERN ILLINOIS
AS THE COLD FRONT MOVES ACROSS THE REGION. ANOTHER SLIGHT RISK FOR
EXCESSIVE RAINFALL IS IN EFFECT. THE URBAN AREAS AROUND CHICAGO
WILL BE WATCHED AS THESE AREAS WILL BE MORE SUSCEPTIBLE TO FLASH
FLOODING IMPACTS.
IMPULSES OF ENERGY EMBEDDED WITHIN A LARGE UPPER-LEVEL TROUGH
MOVING ACROSS THE WEST WILL BRING HEAVY MOUNTAIN SNOW IN HIGH
TERRAIN. WINTER WEATHER ADVISORIES ARE ACTIVE ACROSS MOUNTAIN
RANGES OF MONTANA, WYOMING, AND COLORADO. HALF A FOOT OF SNOW TO A
FOOT ARE POSSIBLE IN THE HIGH ELEVATIONS. THIS SNOW IS BENEFICIAL
TO THE WEST THAT UNDER-ACHIEVED THIS WINTER. THE TROUGH IN THE
WEST WILL BRING COOLER TEMPERATURES TO THE REGION WITH HIGH
TEMPERATURES IN THE 40S AND 50S ACROSS THE INTER-MOUNTAIN WEST FOR
SUNDAY AND MONDAY. LOW TEMPERATURES WILL DROP INTO THE 30S ACROSS
PARTS OF THE WEST, WITH TEENS AND 20S POSSIBLE IN MONTANA.
PARTS OF NEW MEXICO WILL SEE AN EXTREME RISK OF FIRE WEATHER WITH
A CRITICAL RISK EXTENDING INTO WESTERN TEXAS. WEST OF THE DRY
LINE, DEW POINTS IN THE SINGLE DIGITS AND TEENS, COMBINED WITH
WIND GUSTS INTO THE 30S AND 40S AHEAD OF A STRENGTHENING AREA OF
LOW PRESSURE, CONDITIONS WILL BE VERY FAVORABLE FOR FIRE SPREAD.
AVOID BURNING AND LISTEN TO LOCAL AUTHORITIES FOR GUIDANCE.
SIMILAR CONDITIONS WILL BE SEEN ON MONDAY.
