...MULTIPLE ROUNDS OF HEAVY RAIN AND THUNDERSTORMS EXPECTED FOR
THE CENTRAL U.S. THROUGH THE MIDDLE OF THE WEEK...
..SEVERE WEATHER LIKELY FOR PORTIONS OF THE DAKOTAS ON TUESDAY
...HOT WEATHER ACROSS THE PLAINS AND FIRE WEATHER CONCERNS
CONTINUE FOR THE WEST...
A GENERAL AMPLIFIED UPPER LEVEL FLOW PATTERN WILL BE IN PLACE
ACROSS THE CONTINENTAL U.S. THROUGH THE FIRST HALF OF THIS WEEK,
WITH A UPPER TROUGH SITUATED ACROSS THE NORTHWESTERN QUADRANT OF
THE COUNTRY, AND AN UPPER RIDGE AXIS ACROSS THE SOUTHERN PLAINS
INTO THE SOUTHEAST. AT THE INTERFACE OF THESE FEATURES WILL BE A
DEVELOPING LOW PRESSURE SYSTEM THAT WILL AFFECT THE NORTHERN
PLAINS TUESDAY INTO EARLY WEDNESDAY. HIGH INSTABILITY AND WIND
SHEAR PROFILES ARE FAVORABLE FOR THE DEVELOPMENT OF SEVERE
THUNDERSTORMS ACROSS THE DAKOTAS ON TUESDAY, WITH AN ENHANCED RISK
OF SEVERE STORMS IN THE LATEST SPC CONVECTIVE OUTLOOK FOR THAT
TIME PERIOD. THE MAIN THREAT WITH THESE STORMS WILL BE DAMAGING
STRAIGHT LINE WINDS FROM ORGANIZED LINES OF INTENSE CONVECTION,
WITH HURRICANE FORCE WIND GUSTS POSSIBLE WITH THE STRONGEST STORMS.
IN TERMS OF RAINFALL, THE GREATEST CONCENTRATION OF SLOW MOVING
STORMS WITH HEAVY DOWNPOURS IS FORECAST TO BE ACROSS KANSAS
THROUGH TUESDAY AFTERNOON, AND ALSO ACROSS KENTUCKY AND TENNESSEE
THROUGH WEDNESDAY, WHERE THE POTENTIAL CURRENTLY EXISTS FOR 2 TO
PERHAPS 4 INCHES OF RAINFALL IN SOME LOCALIZED AREAS. THERE IS A
SLIGHT RISK OF EXCESSIVE RAINFALL FROM WPC TO ACCOUNT FOR THIS,
EXTENDING FROM WISCONSIN TO NORTHERN GEORGIA. SOME LOCALLY HEAVY
RAINFALL IS ALSO EXPECTED FOR WESTERN WASHINGTON AHEAD OF A STRONG
PACIFIC STORM SYSTEM THAT WILL AFFECT THE REGION THROUGH TUESDAY.
IN TERMS OF TEMPERATURES, IT WILL REMAIN HOT ACROSS THE CENTRAL
AND SOUTHERN PLAINS THROUGH WEDNESDAY. FOR THE EAST COAST, A
SLIGHT COOL DOWN ALONG WITH LOWER HUMIDITY IS EXPECTED ACROSS THE
MID-ATLANTIC AND THE NORTHEAST THROUGH TUESDAY AS CANADIAN HIGH
PRESSURE BRIEFLY MOVES IN, BUT IT GETS HOTTER GOING INTO WEDNESDAY
AND BEYOND. ACROSS THE INTERMOUNTAIN WEST, FIRE WEATHER CONCERNS
WILL CONTINUE THROUGH MIDWEEK, WITH HOT AND DRY CONDITIONS ALONG
WITH GUSTY WINDS CREATING A FAVORABLE ENVIRONMENT FOR POTENTIAL
WILD FIRES.
